Our Work > Buildings


We’re catalyzing massive market growth for buildings that are more productive, valuable, healthy, and safe for the people who occupy them, society, and the planet.

In the United States alone, we aim to reduce 390 trillion BTU’s for 4 billion square feet of space. This is the equivalent of decommissioning 17 coal-power plants. The buildings in which we work, live, learn, and play threaten our climate, our economy, and our health while also posing an increasing financial risk to owners and investors. As the biggest consumers of power, buildings can literally make or break the critical transition to a low-carbon energy future.


Pathways to Zero

We are catalyzing the market for superefficient and net-zero buildings and districts that vault NZE from niche to mainstream—demonstrating how going zero can save energy and money, reduce environmental impact, increase resilience, and better improve occupant health, comfort, and productivity.

We work in both developed and developing markets to increase demand for more productive buildings by demonstrating exceptional value—beyond energy cost savings—to owners, occupants, and the environment.

We are shifting the paradigm of building energy use from one focused on cost reduction, to one focused on energy productivity; supporting the global transition to a clean, cost-effective, renewably-powered electricity system.
