The program was developed to by National Institute of Standards and Technol-
ogy (NIST) to support LCC evaluations. BLCC is used to evaluate life-cycle
costs for a building and to evaluate the impact of energy and water cost saving
measures on life-cycle costs. BLCC allows users to compare life-cycle costs
for various energy and water conservation measures with user-supplied energy
and/or water usage rates and prices. It allows users to decide between construc-
tion options (e.g., whether to use a higher initial cost energy system to reduce
energy costs throughout the building life). Costs of different options can be
compared. BLCC computes life-cycle costs, savings-to-investment ratio, net
savings, internal rate of return, and cash fl ows for project alternatives. BLCC
complies with International standards related to building economics. Detailed
information on BLCC methodology is available from the Life-Cycle Costing
Manual (NIST Handbook 135) for the Federal Energy Management Program.
The BLCC program can be downloaded from the following website:

ures and Tables M1, M2 and M3 illustrate input and output information for
the BLCC Program.
