Careers with NBI

New Buildings Institute (NBI) works collaboratively with industry market players—governments, utilities, energy efficiency advocates and building professionals—to promote advanced design practices, innovative technologies, public policies and programs that improve energy efficiency. We also develop and offer guidance and tools to support the design and construction of zero energy / carbon neutral buildings.

Throughout its 20-year history, NBI has become a trusted and independent resource helping to drive buildings that are better for people and the environment.

We envision a transformed built environment that is carbon-free, sustainable, and energy-efficient and supports thriving economies that benefit all people and the planet. With this vision, we then set out to create the research that informs our tool and policy development aimed at creating market change.

We will continue to fuel innovation that accelerates adoption of “next” practice in energy performance by the energy efficiency and building industries. We are helping to create a future where the built environment represent an effective use of resources, a positive force against climate change, and a driver for local economies that creates jobs and saves money for homeowners and business on energy costs.
