High Impact Technologies

High impact technologies (HITs) are cost-effective, underutilized energy-efficient building technologies. Through the High Impact Technology Catalyst program, the U.S. Department of Energy (DOE) identifies HITS and guides them through their early market introduction phases, ultimately deploying them to the broader market through partnerships with the commercial buildings industry.

The current HIT List is based on the evaluation of almost 500 building technologies. DOE initiate market transformation activities for these technologies with support from federal leaders, regional non-profits, utilities and efficiency organizations through the Better Buildings Alliance.

Looking to demo high impact technologies in your building?

The High Impact Technology HQ is a one stop shop for information associated with technology demonstrations in occupied, operational buildings. Many technology demonstration templates, resources and final results are dispersed across programs and partners. The HQ brings these resources together and will be updated frequently, as new opportunities, resources and outcomes become available.

Be recognized for exemplary practices producing high impact technology savings by joining a Better Buildings Alliance Technology Research Team or participate in an adoption campaign.

Hundreds of organizations are installing or upgrading their buildings for better energy performance and occupant satisfaction. The results have been tremendous. Since the first campaign launched in 2013, over 19 trillion BTUs have been saved -- with over 6 trillion BTUs and nearly $200 million in savings reported just in 2018 -- with even greater savings possible as replication continues into the future.

DOE partners with key stakeholder groups like BOMA, IFMA, ASHRAE, and the Building Commissioning Association (BCA) for strategic technical expertise and to access broader and more diverse networks of potential participants.

Together with supporting organizations, such as utilities and non-profits, both private and public sector building owners tap into a larger network of technical expertise and have the chance to be recognized in front of their peers for exemplary results.

Advanced Rooftop Unit Campaign
The Advanced RTU Campaign encouraged commercial building owners and operators to replace their old RTUs with more efficient units or to retrofit their RTUs with advanced controls. 

Interior Lighting Campaign
The Interior Lighting Campaign (ILC) is a recognition and guidance program designed to help facility owners and managers take advantage of savings opportunities from high-efficiency interior lighting solutions.

Lighting Energy Efficiency in Parking Campaign
The Lighting Energy Efficiency in Parking (LEEP) Campaign was a recognition and guidance program enabling facility owners and managers to take advantage of savings opportunities from high-efficiency lighting solutions in their parking facilities. Closed in 2017; members collectively saved more than $23 million annually. 

Smart Energy Analytics Campaign
The Smart Energy Analytics Campaign encourages the use of a wide variety of commercially available Energy Management and Information Systems (EMIS) technologies and ongoing monitoring practices.
