DCAS runs FELL in collaboration with the City University of New York's Building Performance Lab. The Field Equipment Lending Library (FELL) enables City staff to borrow energy-related field testing and diagnostic equipment to evaluate the performance of their buildings and identify operational issues. FELL staff can also help City staff select the correct tools to diagnose building issues and get trained to use them. To date, staff from 20 City agencies have borrowed equipment to help improve the performance of their buildings. FELL offers free courier delivery service to City staff throughout the five boroughs.
FELL resources are available to City staff and public facility building operators.
