The Department of Energy and Environment (DOEE) solicits grant applications from eligible entities (called “Applicant” or “Applicants”). The goal of this Request for Applications (RFA) is to solicit applications for an entity to develop, pilot, and refine a program to help small buildings reduce energy consumption and improve indoor environmental quality by retuning, a process that makes existing energy systems operate more efficiently at low or no cost. The pilot is intended to support implementation of a permanent, self-sustaining program in the District of Columbia (the District). The following programs or offices of DOEE are administering this RFA: The Energy Administration - Data and Benchmarking Division (DBD) of DOEE will administer this RFA. The purpose of this grant is to pilot, analyze, and refine a Small Building Retuning Program for adoption by DOEE to assist buildings between 10,000-50,000 square feet in saving energy and complying with the District’s Building Energy Performance Standards (BEPS). One grantee will be selected to recruit and select a minimum of ten eligible properties, conduct building retuning investigations, implement complementary energy conservation measures, and develop policy recommendations to help small buildings comply with BEPS. Target buildings include houses of worship, affordable multifamily housing units, and mixed-use commercial properties.
