Why Green Building Is Flourishing

Posted by Thu, Mar 26, 2015


In the fall of 2014 the US Green Building Council released an article with facts about the green building industry. Here are some of those facts that stood out, and what they mean to us. These facts are based on national and international data. Since Carlson Studio Architecture has been deeply involved in LEED certification in Florida since 2000, we can add our Florida perspective to the national data.

Here are some real time examples of LEED Certified, green building projects:


98281527_lido-shores-2c-web  On the residential side:

 1. USGC reports- 62% of firms building new single-family homes report  that they are doing more than 15% of their projects green

 2. By 2018, that percentage increases to 84% (per McGraw Hill Construction Company. Green Multifamily and Single Family Homes: Growth in a Recovering Market. June 2014)

3. In 2013 there were 1160 LEED certified residential units in place in Florida.

4. The LEED for Homes rating system is much different than all the other LEED systems. It is cheaper, and easier to use.

5. The system has been expanded to not only include single family homes, but also multi-family homes of low rise and mid-rise configurations.

13328059_lido-shores-2b-web  The Non Residential Side:

 1. USGBC reports - 41% of all nonresidential building starts in 2012 were green, as compared to 2% of all nonresidential building starts in 2005.

(per McGraw Hill Construction (2012). Green Building Market Sizing, drawn from Dodge Project Starts and Construction Market Forecasting Services, as of March 2012)

2. We saw saw a similar trend in Florida during the same time period.

3. In 2009 there were only 9 LEED certified commercial projects in Florida.

4. By 2013 there were 716 certified commercial projects in Florida, plus 182 projects K-12 and Higher Ed. Projects.

This last statistic shows significant traction through a very bad time of recession.

You probably know by now how much energy buildings use. Energy use in the United States looks like this:

  • Buildings use 41%
  • Industrial uses 30%
  • Transportation uses 29%

Buildings are one of the heaviest consumers of natural resources and account for a significant portion of the greenhouse gas emissions that affect climate change. In the U.S., buildings account for:

  • 38% of all CO2 emissions (per Energy Information Administration (2008). Assumptions to the Annual Energy Outlook.)

73% of electricity consumption (per Department of Energy 2011. Buildings Energy Data Book. Buildings Share of Electricity Consumption/Sales. Accessed October 26, 2011)


Green buildings consume less energy. Compared to the average commercial building, the LEED Gold buildings in the General Services Administration’s portfolio generally (per U.S. Department of Energy (2011). Re-Assessing Green Building Performance: A Post Occupancy Evaluation of 22 Buildings)

  • Consume 25% less energy and 11% less water
  • Have 19% lower maintenance costs
  • 27% higher occupant satisfaction
  • 34% lower greenhouse gas emissions

And where in the Country is green building doing well? USGBC says….

Top 10 States in the U.S.A. for LEED: Registered & Certified, per capita (as of February 2015)

  1. Illinois
  2. Colorado
  3. Maryland
  4. Virginia
  5. Massachusetts
  6. Hawaii
  7. California
  8. Georgia
  9. Minnesota
  10. (tie)New York
  11. (tie)Arizona

 Where is Florida on this top 10 list?

Lessons Learned From OUR LEED For Home Charrette

Posted by Fri, Mar 13, 2015

Tags: gold LEED, Energy Efficiency


LEED-Charrette-Render-1 Carlson Studio Architecture is currently designing a LEED for homes project in Michigan. As part of the design process we held a LEED design charrette with the contractors, material suppliers, designers and subcontractors of the project. This highly interactive, brainstorming session brought the entire team together to strategize the project. Getting a bunch of smart people together to think about the project holistically was important -some of the things that we learned are as follows:

Other Projects That May Interest You:


There Are 4 Areas Of Focus The Came From This LEED Charrette:

1. Landscape:

We learned there were many credits available in the landscape categories. This includes water conservation in the irrigation system and native plantings and native low impact design solutions. Since we are working on an existing site we may choose to remove some of the existing impervious surfaces and replace them with landscaping and/or pervious surfaces. The landscaping and irrigation credits will be important to us if we are to achieve our certification goals.  Mike Bruggink, Fen View Design, is the Landscape Architect.

2. SIPs (Structural Insulated Panels)

We learned that LEED encourages and rewards the use of sip panel construction in the LEED for homes standards. SIPs should help us obtain a very good HERS rating, create a well-insulated and tightly constructed building envelope, speed up construction and reduce waste. Rich Bloem of True North Homes has an extensive background in SIP construction.

3. Lumber

Our current LEED home is planned to be constructed of wood. In addition to the SIP panels which have wood faces, we plan to use wood floor joists and wood trusses to complete the building envelope. We plan to source all of these materials locally and regionally it's close to the site is possible. We did determine that FSC certified wood was going to be very difficult and expensive to get for this particular project and have decided to not pursue FSC certified would based credits. We did look at the advantages and disadvantages of open web wood floor trusses versus TJI style pre-engineered floor trusses.   There were representatives of each style of truss at the charrette which was incredibly valuable to the team. Because of the somewhat complex geometry of the floor framing systems we decided to go with the TJI style floor trusses on this particular project. Jed Nelson and Mark Paradowski, from Barry County Lumber Company where in attendance.

3. Plumbing

We are looking at using Kohler brand fixtures for this particular project. We learned that there are many options to choose from but this and other major manufacturers all do high-quality low flow fixtures that meet the highest standards in the LEED credits. We plan to use the best performing, low flow fixtures for this project. We also plan to supplement the gas fired water heater with solar thermal system(s) mounted on the roof to preheat the water and save us energy. Ross Genzink, Genzink Plumbing was in attendance.

We offer a simple but important checklist you can use when isolating certain elements that will make your home more "Green" and actually save you energy and money. Just use the button below:

Tips To Make Your Home Green



These are just a few of the things we learned in the integrated design process for this project. We look forward to completing the permit documents, bidding the project, and getting construction underway in the spring.

Designing, planning and constructing a LEED for homes project may be a challenge but it is one with invaluable foresight. As this process becomes more and more popular, both consumers and commercial entities will learn and experience all of the benefits and even more important, will play a role in turning around so many environmental issues including something as massive as the world's climate change challenges.

If you or your business is in the research phase of a creating or remodeling a structure, we strongly encourage you to do your homework and research. We are here to help you answer many of the critical questions that arise from such an undertaking and would like to offer you additional information or a no cost consultation.

Managing A Successful LEED Charrette

Posted by Mon, Mar 09, 2015

How To Manage A LEED Charrette - A Real Time Example:

We have completed our LEED charrette for our single-family home that we are designing in Michigan. Thanks to Rich Bloem and Alex Goosen from True North Homes (general contractor) for their assistance in putting the charrette together and facilitating the day.

Wikipedia definition of a Charrette: "While the structure of a charrette varies, depending on the design problem and the individuals in the group, charrettes often take place in multiple sessions in which the group divides into sub-groups. Each sub-group then presents its work to the full group as material for further dialogue. Such charrettes serve as a way of quickly generating a design solution while integrating the aptitudes and interests of a diverse group of people. Compare this term with workshop."

Need some other examples of successful charrette results? Check out these LEED projects:


LEED-Charrette-Render-1The first thing one needs to do for a successful charrette is manage the logistics. We met at a great venue called the Pinnacle Center in Hudsonville, Michigan and we were treated with a great conference room full of all the necessary AV equipment that we needed, as well as coffee, breakfast, lunch and breaks throughout the day to make the whole thing very enjoyable. Don't overlook the details and making the participants comfortable during the charrette process.

There are various considerations when executing a productive LEED charrette. Here are a few that we addressed and played a significant roll in the overall outcome.

Number 1: The Players

There were about 20 people who participated in the charrette. Most were there all day. Some came and went. The general contractor, the architect, the landscape architect and many of the subcontractors and material suppliers contributed to the successful day. We discussed all the features of the home and all the systems necessary to construct it in an open forum where everyone contributed. Some had experience in doing green homes and for others this is their first exposure to the process. Several of the participants have been working on preliminary LEED for Homes checklists for the project prior to coming to the charrette. 

Number 2: Credits & The LEED Rating System

LEED-Charrette-Render-3For this particular home, because of its size, we need to achieve 100 credits in the rating system to obtain our goal of platinum certification. Are preliminary checklists were reflecting scores between 88 and 94 credits. The variation was coming mostly from the HERS score which was anticipated to be anywhere between HERS index of 30 and a HERS index of 44. Learn more about the HERS Index process. Alex Goosen is managing the HERS preliminary rating process, and Jamison Lenz is our LEED Provider from the Green Home Institute, Grand Rapids, Michigan. 

Number 3: Teams & Strategies

As a team we went through the entire LEED checklist and looked for synergies between various systems and other design and construction strategies to improve the home's design to a point where he could receive platinum certification. The design itself had already taken into account many passive design elements to make the process easier. The home is already set up with south facing roof to accept PV and/or solar thermal systems to improve the homes energy performance.

Step 4: Trouble Shooting

LEED-Charrette-Render-2One of the most interesting discussions of the day was about the homes heating and cooling systems. It was determined that there are more heating load than cooling load, but that it was important that both heating and cooling be provided. The initial basis for the design was a forced air system for both heating and cooling using highly efficient equipment. And there was a need to make the home more energy-efficient to get it from the gold to the platinum level of certification. The air-conditioning and heating sub-contractor provided great input, and practical analysis, as well as a specialist in renewable energy systems (such as PV, solar thermal and geothermal systems) provided his perspective as well.  After a great deal of discussion and various systems options, we decided to proceed in evaluating a radiant hydronic floor heating system for the first floor, supplemented with a forced air heating system for the second floor that would also serve as the forced air cooling system for the entire house. We will supplement both systems with solar thermal roof mounted water heating to preheat the water needed for the hydronic floor system and PV solar electric panels supplement the entire system including the forced air system cooling and heating. The PV solar system could be in the range of 5 KW to 10 KW. Solar thermal is yet to be sized but it will provide support to a natural gas fired boiler that will help maintain the water temperature under any conditions. Successfully integrating the systems together should improve our HERS score down to the low 30s or maybe better. Also we will integrate the domestic hot water heating with the radiant floor heating by having those two system share their heat energy which will be an important link to save energy.


A LEED charrette is a living and breathing process and each one may be different. After we completed this charrette we walked away having learned a few things:

  • Michigan has true net metering (you may know that Florida does not, shame on the sunshine state)
  • There are many options and heating and cooling systems in Northern climates
  • Forced air heating and cooling is most likely the least expensive first cost solution
  • Hydronic radiant floor systems provide an incredibly comfortable way to heat a home

The return on investment calculations that the subcontractor will provide will help us make a decision between first cost and lifecycle cost for the system that we end up selecting.

Certified Green Buildings Or Just Building Better

Posted by Tue, Mar 03, 2015

The Principles Of Good Design:

If you are looking to 

  • Design a green building or just an efficient building
  • Attain third part certification such as LEED
  • Incorporate principles of good design

You have come to the right place. Carlson Studio can help you. lakewood_ranch_plastic_surgery-resized-170There are many fundamental aspects of good design that we apply to all our projects whether or not they seek certification. Most of these apply to all building types, from homes, to schools, to office buildings, to churches. 

Some World Class Examples? Check out these projects already completed:


Designing beautiful and truly green, sustainable buildings requires experience, commitment and teamwork, and sustainability is applied to all aspects of a project, including site design, energy conservation, water conservation, materials and resources and Indoor Environmental Quality.

One of the key aspects to successful sustainable design is the use of the Integrated Design Process. The integrated design approach that we utilize in all our work allows us to provide high quality, high performance buildings for our clients. We look at our buildings as part of the greater “whole system”. A building is an expression of energy, materials & design (information). Buildings are not comprised of isolated components - each is comprised of systems that interact with other systems including the larger ecological systems and the human community. A “whole system” design leverages the complex and complementary interactions to reduce energy use and levy the smallest possible environmental impact, while enhancing occupants’ comfort and productivity.

The integrated design approach asks the members of the planning, design and construction teams to look at the materials, systems and assemblies from many different perspectives. The design is evaluated for first cost, life cycle cost, quality-of-life, future flexibility, efficiency; overall environmental impact; productivity and creativity, and how the occupants will be enlivened. The most important component of any building is the people who use it. This design approach allows us the freedom to maintain our tradition of diverse architectural solutions without limiting us to particular building types or styles. The strategies we implement result in creating beautiful buildings that are safer, healthier and more efficient 

The Important Strategies We Implement For Each Project:

Focus 1: Site

The building and the site can contribute to the beauty of the surrounding area, support a healthy, diverse biological community and contribute to addressing global environmental and economic challenges that we face.  Examples may include:

  • On-site storm water system and low impact development (LID) practices
  • Plant palette consisting of drought tolerant native and Florida friendly plant species
  • Water-wise low volume drip irrigation which could use a non-potable water source, putting the water on the root zone of each plant minimizing the evaporation rate
  • Pervious pavements, pervious trails, & grass parking help to reduce storm water runoff
  • Light colored hardscape reduce heat island effects created by most development
  • Light Pollution Reduction
  • Encourage Alternative Transportation

Focus 2: Water

The project can demonstrate a new standard of leadership in conserving our precious water resources. Examples may include:

  • The flush/flow fixtures reduce indoor water consumption.
  • On site reclaimed, storm water, or rain water can utilized for flushing of all toilets and urinals reducing potable water use
  • Motion Sensors on Faucets
  • Rainwater Harvesting for irrigation or toilet flushing
  • Water Efficient Landscaping

Focus 3: Energy

Reducing energy use saves money, and directly translates into reducing the emissions of carbon dioxide and other gases that are entering our atmosphere at historically unprecedented levels.  Examples may include:

  • A high performing building envelope saves energy and operating expenses.
  • Roof overhangs provide shade to reduce heat gain.
  • Self-dimming light fixtures adjust for the amount of daylight entering each space to provide an optimal amount of light.
  • Occupancy sensors in offices & other spaces turn on/off lights as needed
  • Timers shut down all the lights at night
  • LED Parking lights are more efficient than traditional
  • High Efficiency SEER DX equipment can stick an appropriate balance between first cost and performance.
  • Energy Recovery Ventilators reduce energy costs and improved indoor air quality and comfort
  • Expansive south facing metal roof provides area for future solar installation
  • Natural Day lighting saves energy
  • HVAC Equipment right sizing.
  • Non-CFC Based Refrigerants
  • Solar Thermal water heating

Focus 4: Materials & Resources

Better process and product design can reduce waste; better product and material selection can reduce harmful effects to our planet; and better life-cycle management can effectively reuse and/or recycle materials rather than discard them into landfills.  Examples may include:

  • Encourage Recycling during construction and during operation.
  • Construction Waste Management: Separate dumpsters used to sort and collect each building material during construction.
  • Collection of recyclables can be a feature in the daily operation of the building.  Design can include central collection areas for recycling.
  • Specify Local and Regional Materials
  • Recycled content in specified materials such as tile, toilet partitions, steel stud framing, etc.

Focus 5: Indoor Environmental Quality

The health and well being of the building user is of utmost importance.  Examples may include:

  • Views to the exterior and views to the natural scenery
  • Use of natural daylight
  • Low VOC Paints & Adhesives
  • Low Emitting Materials
  • Implement an Indoor Air Quality Management Plan, which prevents contaminants from entering the project during construction
  • Indoor Chemical and Pollutant Control
  • Walk off grates at main entrances
  • Carbon Dioxide Monitoring


Successful and cost effective sustainable design looks for synergies between all of the above ideas.   Each idea works in concert with other ideas in the design.

Alternative water technology at the LEED seeking Cancer Support Community

Posted by Wed, Jan 28, 2015

What do you do when your client doesn’t want to install water fountains in their project due to hygienic reasons? Well we dealt with this very issue on the LEED gold seeking Cancer Support HydrationStationCommunity’s (formerly The Wellness Community) Building Hope Project.

Early in the design phase the client made it very clear that people with compromised immune systems were uncomfortable with drinking out of typical water fountains. Of course the building code requires so many water fountains per person in any new construction project. The usual solution of avoiding water fountains is to provide a typical water cooler bottle service. But, being a green project and conscience about the environmental impact of shipping water bottles, we had find another solution.

Searching the internet we had little luck finding a suitable substitution, until we discovered UC Berkeley had recently installed “bottle fillers” called Hydration Stations on their campus. These bottle fillers are made by Haws Corp. a long time water fountain company, and were perfect for the Cancer Support Community. In order to meet Florida ADA code we add matching stainless cup holders besides the units to provide safe, clean water for the buildings occupants.

In addition to being hygienic we were also able to avoid exposing the cancer patients to harmful chemicals often leached out of plastic bottles. The units mount in or on the wall with full ADA clearance and access, saving valuable floor area and even have an LED light for illumination when in use.

From Haws Corp Website: “Daily, Americans use 60-million bottles of water, with only 2 out of every 10 bottles actually recycled.  By using the HydrationStationTM users will be able to utilize re-usable bottles and consequently reduce waste and its harmful effects on the environment. Several college campuses, including UC Berkeley, Georgian College in Ontario and Penn State, have already taken the initiative and supported a ban the bottle approach to water supply and have installed HydrationStations throughout their campuses.”

Design challenge: Creating a facility that symbolizes Hope

Posted by Wed, Jan 21, 2015

Tags: green, architecture, lakewood ranch, wellness

This project was done in 2011 but the story of the design challenge is timeless!

The Cancer Support Community (formerly known as The Wellness Community) wanted a new facility that would be a place of healing and a beacon of Hope to those affected by cancer.  How does architecture convey a sense of Hope to the buildings user?

Cancer Support Community Architecture

The design solution for the 11,000 SF facility was to create two structures connected together by a large arch that creates a covered courtyard.  The prominent arch stretching across the facility serves as an inspiring design element but also offers a compelling story of history and hope.  Known as the “Bridge of Hope”, the arch connects the 2 pavilions and is a tangible testament of hope to all who enter.  The abstract form allows for interpretation about what the symbol represents to each individual.  

The arch is a traditional architectural design element signifying strength and permanence.  The shape of this particular arch is much like a rainbow in the landscape.  The rainbow is a timeless symbol of hope (think Noah). Visitors gain an empowering sense of comfort from the structural strength when walking beneath the arch.  The arch is supported by 8 pillars that are old Florida hard wood Pine tree trunks, from trees that were several hundred years old and were originally harvested over 100 years ago when Florida was first harvested for its timber.  During transport down Florida’s rivers, logs would frequently be lost along the way and sink to the bottom of the Suwannee River.  This environment actually preserved the timber until it could be reclaimed recently for this project.  These tree trunks were stripped of their bark, but left a bit rugged and scared, in their natural state.  They stand at the entry and in the courtyard as if they were old friends, there to provide a since of comfort and longevity.

The arch structure above the tree trunk columns is constructed of laminate wood beams and tongue-and-groove decking, both of which are Forest Stewardship Council (FSC) certified wood.

The Bridge of Hope clearly defines the main entry of the facility so users are comfortably orientated when they arrive at the facility.  While the arch for does dominate the image of the facility, the rest of the building is scaled down to be welcoming and easily approachable.  It is more of a residential scale with simple one-story forms and familiar, simple pitched-roof shapes.  The project is designed to avoid any sort of medical or institutional feel and is instead full of friendly warm materials and spaces to provide the user a peaceful and comfortable environment that reminds them of home.

The facility sits in the natural landscape adjacent to a wetland preserve.  The “Bridge of Hope” stands as a symbol for all who work in and visit the Cancer Support Community.

This article appears in SRQ magazine’s March 2011 issue titled “Design Dossier".

Function of the building: Healing Center to deliver optimum care in the areas of psychological and social support to people affected by cancer – those with the disease as well as their loved ones and caregivers.

Sarasota Green Building Exemplifies Sustainable Design

Posted by Wed, Jan 21, 2015

Tags: green building, Sustainable Design, Green Design

Call it sustainable. Call it high performance. Building green is the common sense approach to improving operating efficiencies while decreasing environmental impact, and creating the healthiest environment for the building’s occupants.

Did you know that in the U.S., buildings account for:

    • 36% of total energy use / 65% of electricity consumption
    • 30% of greenhouse gas emissions
    • 30% of raw materials use
    • 30% of waste output /136 million tons annually
    • 12% of potable water consumption

With numbers like these, how can anyone be resistant to the idea of going green? The benefits to our environment are invaluable, and the result of sustainable design also benefits the bottom line; it's a win-win, no matter how you look at it.

Twin Lakes Park Office Complex – A Golden Example of Going Green

Twin Lakes Park Office ComplexOnce used as a dormitory for a professional baseball team, the Twin Lakes Park Office Complex in Sarasota, Florida was later refurbished to become as one of the “greenest” office buildings in the state. The project is recognized as the area’s first “green” office complex, and serves as a model for the simplicity and savings associated with going green.

Many environmental factors were taken into consideration for this project, including:

    • Erosion and sedimentation
    • Run-off reduction and storm water management on-site
    • Minimal site disturbance.

Sustainable DesignThe buildings’ orientation to the sun and strategic window placement ensures maximization of northern sunlight for day-lighting within the buildings, enabling heating from the sun during winter months and optimal shading during the summer.

Any electric lighting in the building is automated to monitor and adjust light levels, reducing energy waste. These lighting methods lead to a cost reduction of 40 to 60 percent.

Here’s a closer look at some energy-efficient features that make Twin Lakes green:


    • Pervious concrete sidewalks and patios minimize storm water runoff
    • Energy-Star reflecting roof reduces heat absorption and heat island effects
    • Contained construction/development area to a minimum to disturb as little surrounding land as possible and ensure maximum green space
    • Covered bike rack and shower/changing facilities encourage to encourage employees to choose alternative transportation for their commute to work, such as walking or riding their bike.

Water Efficiency

    • Uses 58% less water than a new code compliant office building
    • 28,000-gallon cistern collects rainwater for toilets and irrigation
    • Water efficient, native, climate tolerant plants used in landscaping
    • High efficiency irrigation system relies on cistern-collected rainwater
    • Super-efficient plumbing fixtures, such as low flow toilets, waterless urinals and motion sensor sink faucets, reduce water consumption

Energy Efficiency

    • Uses 45% less energy than a new code compliant office building
    • High performance building envelope and glazing system provides improved insulation and energy-efficiency
    • Photovoltaics (solar panels) generate 5% of building’s electricity
    • Solar water heating, natural day lighting and motion detection lighting reduce energy consumption
    • Geothermal HVAC cooling system saves energy and uses ozone-friendly refrigerants

Materials and Resources

    • 89.7% of existing structure of Building A maintained for reuse
    • Materials with recycled content used in both interior and exterior
    • Recycling room reduces amount of waste hauled to landfills
    • Materials manufactured locally or regionally minimize cost and impacts of transportation

Indoor Environmental Quality

    • Environmentally-friendly adhesives, sealants, paints and carpet
    • Carbon dioxide monitor
    • Separate exhausts in janitor closets reduce exposure to potentially
    • hazardous chemicals
    • Smoke-free environment
    • Natural day lighting and views of the exterior throughout

In addition to achieving the primary goal of reducing environmental impact with this green building project, the advantages of these upgrades are readily seen in resulting bottom line benefits:

    • Integrated design optimizes energy performance to be 50% more energy-efficient than standard buildings
    • Interior day-lighting methods decreased lighting costs by 40 to 60%
    • This facility is equipped to use 58% less water than a typical code-compliant office building

CSA Green Building – A Model for Sustainable Design

Posted by Sun, Jan 11, 2015

Tags: green building, Sustainable Design

Michael Carlson could give Kermit the Frog a run for his money.  Carlson, AIA, NCARB, LEED AP, principal and founder of Carlson Studio Architecture, wants Sarasota to know that being green is easier than you think.  At his firm’s corporate headquarters near Fruitville and Orange in downtown Sarasota, he’s living by example.

Carlson Studio ArchitectureFounded in 1997, Carlson Studio Architecture is celebrating its 18th year anniversary in March 2015. Carlson himself has lived in Sarasota for over twenty-eight years.  His first exposure to green building happened while he was an architecture student at Ball State University in Indiana.  There he worked with professors and classmates in the university’s Center for Energy Research/Education/Service.  But it wasn’t until 2000 that he fully dedicated his practice to sustainability.

Green Building Increases Value, Lowers Cost

The staff at Carlson Studio Architecture incorporates green design principles into every project.  According to Carlson, with the advances in building materials, the cost of a green project isn’t necessarily greater than the cost of a quality non-green building.  The nature of sustainable design is that it is long-lasting and low maintenance.  These attributes help to increase long-term value while decreasing cost associated with upkeep. 

“Sometimes a client will be cutting-edge green,” Carlson reveals.  “Other times, we might have a project where we’re ‘stealth green.’  This is when a client may not be interested in sustainable design, but we still can make simple, responsible choices without raising costs.”

Examples of “stealth green” specifications include low-chemical paint.  Even when a project isn’t destined to be green, low-VOC paint can be specified; it’s better for the environment and the health of the builders and future tenants. While all business owners are motivated by different reasons, Carlson believes that sustainable design is the right thing to do. 

“Architecture is more meaningful and purposeful when sustainability is a factor,” says Carlson.  “In the age-old discussion of form verses function, I work to join aesthetic and utility through sustainable design.

At Carlson Studio Architecture, about one-third of the projects are residential, leaving the remaining two-thirds devoted to commercial developments.  The firm concentrates on Sarasota, Manatee, DeSoto, Hardee and Hillsborough counties, but has completed projects all over Florida and a few out of state.

In designing his Sarasota headquarters, Carlson set out to renovate the historic Cheney Building to meet the LEED (Leadership in Energy and Environmental Design) silver designation for Commercial Interiors (CI). 

Sustainable Design

LEED-CI is the industry benchmark for green design and construction of tenant improvements.The focus is on proven contributors to employee productivity and well-being in four areas:

  1. Thermal comfort
  2. Access to daylight and views
  3. Minimizing interior pollutants and energy
  4. Water conservation techniques. 

The LEED certification process benefits the consumer in two ways:

  1. Third parties certify that buildings have met the criteria for environmental health
  2. The market begins creating products to meet these standards. 

The Cheney Building renovation began in January 2007.  Carlson Studio Architecture moved into the space in June 2007, and the project was fully completed in August.  LEED-CI Certification (Silver level) was achieved in December 2007.  The project was just the 3rd LEED-CI project in Florida at the time.

Green Building

According to the U.S. Green Building Council, a healthy workplace environment enhances individual well being and productivity while reducing employee absenteeism and operating costs.  Carlson’s team employed several resources to transform the 1930’s grocery store into a professional office complex that reduces environmental impact, maximizes occupant comfort and improves building performance:

  • Transparent interior walls enable each workspace to have access to the increased daylight and outside views afforded by the oversized windows and glass doorways that Carlson added.

  • Cork and Interface carpet tiles were specified underfoot.  Cork is a replenishable material since only the bark is harvested, while the Interface carpet tiles are chemically free, include recycled content and are carbon neutral.

  • All glues, sealants, caulks and paints are chemically free and produce low VOCs with no “off gassing,” (VOCs, or Volatile Organic Compounds, have been identified as cancer-causing agents).

  • To continue minimizing indoor pollutants, the office is cleaned with green housekeeping methods and non-odorous cleaning products.

  • Converted “low-flow” plumbing and other features help to conserve water and energy.  Carlson estimates that installing these conservation measures will reduce water usage by thirty percent.

“We promote green buildings and green interiors to our clients every chance we get – and now we made the same decisions about cost and materials that our clients make every day,” said Carlson.

While only the interior of Carlson Studio Architecture is being considered for LEED-CI certification, improvements were made to the entire Cheney Building.  With investment partner Victor Appel, ASID, Carlson replaced the roof with an Energy Star roof to maximize efficiency.  Adding extra insulation and high-performance glass also reduces energy use.

By way of their own practice, Carlson Studio Architecture is committed to quality design solutions that promote commercially-viable sustainability by minimizing the consumption of materials and maximizing their reuse, all while protecting the environment. 

With Carlson’s easy tips, we all can be a little greener without breaking the bank:

  1. Replace light bulbs with compact fluorescent bulbs and energy efficient T-8 fluorescent tube lighting (both are widely available).
  2. Use low-VOC paint offered by most name-brand paint manufacturers.
  3. Buy Energy Star appliances to increase the efficiency of your energy and even water use.
  4. Increase insulation, especially in the attic, and use an efficient air conditioning system. 

“Even small changes can make a big difference, and it’s easier than you think,” says Carlson. 

Sarasota architecture firm’s LEED-CI (Silver) green building offices demonstrate how easy it is to incorporate sustainable design into projects.

Sustainable Buildings - Certification Makes A Difference

Sustainable Building Certification

The next great debate in the building & design industries will not be whether to build green or not – it will be whether or not to build to third-party standards and seek a green building certification.

The advantages of green or sustainable building are both numerable and measurable. Sustainable buildings result in increased productivity. For example, studies published with the US Green Building Council report that

  • Students attending green schools produce 20% better test results than their peers in conventional classrooms
  • Patient recovery in green health care environments results in improved discharge rates of 2 days or more on average
  • Retail sales are higher and worker productivity in offices is reported to increase by 2-16% depending on the green features employees enjoy in their jobs.

Asustainable building certificationdditionally, operating savings for sustainable buildings can be as much as 50%, occupancy rates, as well as rent, are reportedly 3-4% higher. Building owners who choose green methods of construction or renovation are often rewarded by government with fast-track permits, energy rebates and other monetary incentives.

Sustainable design, also called “green” or high performance building, provides economic, human and community benefits as well as reduced environmental impacts.
So pretty soon, we won’t be talking “if” green … the conversation will shift to “how” green.

As sustainable architects here in Sarasota, our firm encourages our clients to build green – all right, we actually design green features into every project whether a client requests them or not because the reality is that it doesn’t cost any “extra” to include basic and practical sustainable building design principles like:

  1. Building orientation
  2. Natural daylighting
  3. Energy-efficient HVAC
  4. Low VOC paint
  5. Many other examples as well

In 2007, we purchased a 1930s era grocery store in downtown Sarasota for the purpose of renovating it to LEED Commercial Interior (CI) standards to become our firm’s new headquarters.  We divided the 4,400-square-foot building and occupy 2,400 square feet.  Our renovation costs were roughly $85 per square foot.  Our sustainability features included:

  • Double-pane thermal windows and doors
  • Added insulation
  • Energy star rated reflective roof system
  • Energy efficient HVAC
  • Low energy fluorescent lighting
  • Low flow plumbing fixtures 
sustainable buildingWe consciously made the choice to seek LEED certification for the project – over and above the fact that our building decisions met the criteria – for two reasons.  If we are going to encourage our clients to seek certification, we should walk the walk.  And we recognize the investment payoff that third-party certification represents.  We chose the LEED system, over other available systems, because LEED standards are rigorous.  Anyone can say they built green, but everyone knows that if LEED says it’s green, it’s certifiable.

Our commissioning fees and extra costs for construction measures we chose were $8,900 including our USGBC membership based rate of applying for certification.  (The USGBC lists fixed rates for certification fees ranging between $1,250 and $22,500, depending on square footage and USGBC membership status). This added a $3.71 cost per square foot to our renovation, approximately 4% to the budget, but we have seen our investment pay off through marketing and branding exposure as well as real property appreciation.  

Other certification systems may be cheaper and easier, but because they don’t have the brand power of LEED, some detractors say they offer a less verifiable way of certifying the green-ness of a sustainable building project.  But these other systems, including the National Association of Home Builders’ new program, Energy Star, Florida Green Building Coalition and the newest arrival, Green Globes, are generating increased buzz about how green to go.  Meanwhile the common denominator is a shared desire to validate sustainable building design.

Our industry is transforming itself not only because the health of the planet is at stake, but because there is sufficient momentum and incentive to move in this direction.  Regardless of which certification method is selected, green standards are here to stay.
