Leaders in sustainable engineering design
Our high-performing buildings work because our people listen—to our clients, to each other, and to the natural world around us.
Collaborative approach that drives results
We work together with architects, building owners, developers, and other key stakeholders to ensure that projects get done right the first time—on schedule and on budget.
Designs that make an impact
From apartments and workspaces to schools and hospitals, we approach all projects with the same goal in mind: To help people live and work better, and learn and heal faster—all while restoring the planet.
Thermal comfort is about more than just temperature. There are actually six factors that influence how comfortable we feel when we’re inside a building. Thermal comfort is determined by air temperature, radiant temperature, air speed, humidity, metabolic rate, and clothing level.
A Net-Zero Energy building is one that produces at least as much energy through renewable sources as it uses in a year. Currently, there are very few Net-Zero buildings in the U.S., and most of them are small—but you’re about to start seeing a lot more of them.
