Sustainability
As a member of the U.S. Green Building Council, CTA embraces sustainable building practices. We wholeheartedly accept our responsibility and leadership role in advancing design and building practices that promote efficient and healthly buildings and protect our natural resources.
New Technology
Necessity is the mother of invention. CTA is populated with professionals who are finding solutions before the questions are even asked.
An excellent example of CTA's dedication to new technology adaptation is Montana's Amsterdam Village. CTA has incorporated a membrane bioreactor (MBR) wastewater treatment system in to the design phase for this planned community. The MBR system returns water to near-drinking quality, reusing it for lawn irrigation and recharging the groundwater aquifer.
LEED Credentials
LEED stands for Leadership in Energy and Environmental Design - and at CTA we have increased our leadership by quadrupling our number of LEED-accredited professionals over the last year.
Walking the Walk
Our LEED accredited professionals, our energy conservation and alternative energy design solutions, and our on-going training in sustainable design practices demonstrate our commitment to protecting our environment.
Featured Sustainability Projects
Old Faithful National Park Visitors Education Center
Meets LEED credits for regional and recycled materials; and has specified low-emitting adhesives, paints and carpets
Gold's Gym Meridian
"Cellular Beam" structural systems and roof monitor day-lighting strategies
Star Sewer and Water District
A membrane bioreactor system (MBR)
Harney Hospital
Regionally available materials and an efficient heat pump mechanical system
USGS National Wetlands Research Center
Sustainable design elements and a leading edge storm water management system
Worland Middle School
HVAC system stores excess heat to use at night during occupied times
CTA Billings Office
Resurrected from a dilapidated warehouse, this 1920s renovation uses over 75% of the original building. Entwined throughout the new CTA Billings office are countless demonstrations of the design team's thoughtfulness and respect for the environment.
Green roof garden: Located just outside the second floor conference room. This 2,500 square foot green space serves as a thermal barrier from extreme temperatures and helps save on heating and cooling loads.
Operable windows: Providing soft, natural daylight. Perimeter lights by the windows have photo sensors that turn the lights off when enough daylight is available. Dimmers control light in the conference rooms, and the emergency generator runs on natural gas.
High efficiency condensing boilers: Five boilers operating at up to 98% efficient and modulating from 100% capacity down to 20% individual capacity. This eliminates starting and stopping of boilers, which is a large energy consumer.
Low-pressure cooling system: A variable air volume air-handling unit with 100% outside air capability and a three stage cooling system. The low pressure means that for a given air flow, less horsepower is being used than with your typical variable air volume air handling system.
Sustainable finishes and features:
- Crossville GeoStone Eco Cycle tile in the bathrooms:
- LEES 'Visio' Carpet: contains a high recycled content
- Sherwin Williams 'Harmony' line of low-VOC paints
- ABET Laminiti 'Tefor' line of plastic laminates cover the cabinet bases
- Wall coverings in the conference rooms are fused wood fibers in latex
- Countertops are made from wood fiber waste
- All sealers are water-based
- All steel parts are recyclable and contain recycled content
- Low-flow fixtures in all restrooms
