Building Technologies Office (BTO)’s overall goal is to improve the energy productivity of buildings without sacrificing occupant comfort or product performance. The goal is to use energy more productively and efficiently, not simply to use less energy. Progress towards achieving this goal will make building energy costs more affordable to the benefit of American families and businesses.

BTO research is focused on reducing energy intensity for major segments of the sector with the most opportunity for energy savings, while balancing the need to maintain occupant comfort and productivity, and product performance. This includes both new and existing buildings, both residential and commercial, including their energy-consuming and labor-saving equipment. The development of next-generation building technologies, including building materials, components, equipment, energy models and systems, is critical to increasing energy productivity in a cost-effective manner.

BTO’s Emerging Technologies (ET) program invests in the research and development to create the next-generation building technologies, tools and systems to enhance energy efficiency. The program focuses on the most energy-intensive technologies for residential buildings and in commercial buildings, where the opportunity for cost-effective energy savings is greatest. These technologies include air conditioning, space heating, water heating, lighting and sensors & controls, all of which are addressed in this FOA.

Achieving BTO’s priorities across the building technology landscape requires sustained, multifaceted innovation. With this FOA, BTO intends to fund high-impact, early-stage research in the following areas:
Topic 1: Flexible Building Technologies
Topic 2: Heating, Ventilation and Air Conditioning (HVAC) Technologies
Topic 3: Solid-State Lighting (SSL) Technologies
