We believe sustainability is an outcome, not a point count. It’s a philosophy we use to increase our clients’ efficiency and productivity, maximize the return on their investments, and to create safe, healthy environments that support their commitment to their people. It’s also how we contribute to minimizing the impacts of climate change and building a better built environment. 


There are many goals in sustainable building design. Some aim to decrease energy consumption. Others focus on reducing the use of non-renewable resources, materials or processes harmful to the environment. And, most seek to increase efficiency and reduce operating costs. Some goals aim to enhance less quantifiable aspect such as: improving air quality, occupant comfort and health, encouraging research into alternative processes, responsible use of materials, and low energy transportation.

How we design building systems starts with our philosophy of establishing a project strategy that will deliver a sustainable building. There is no one silver bullet that delivers a sustainable performance; it requires myriad building systems to work efficiently together. Systems to be considered include:

  • Low carbon district energy solutions
  • Alternative Fuel Systems
  • Cogeneration
  • Wind
  • Photo Voltaic (Solar)
  • Geo-exchange
  • Energy storage (batteries)
  • Heat and energy recovery systems

We have deep experience designing building systems that meet or exceed industry benchmarks such as:

  • LEED – NC, EB&OM, CI
  • WELL
  • Net Zero
  • Living Building Challenge
  • Passive House
