The Building Life-Cycle Cost Program

The Building Life-Cycle Cost Program BLCC 5.3-07 is a program developed by the National Institute of Standards and Technology (NIST) to provide computational support for the analysis of capital investments in buildings.

The BLCC computer programs conduct economic analyses by evaluating the relative cost effectiveness of alternative buildings and building-related systems or components. Typically, BLCC software is used to evaluate alternative designs that have higher initial costs but lower operating-related costs over the project life than the lowest-initial-cost design. It is especially useful for evaluating the costs and benefits of energy and water conservation and renewable energy projects.

Building Life-Cycle Cost

The life-cycle cost (LCC) of two or more alternative designs are computed and compared to determine which has the lowest LCC and is therefore more economical in the long run. BLCC also calculates comparative economic measures for alternative designs, including Net Savings, Savings-to-Investment Ratio, Adjusted Internal Rate of Return, and Years to Payback.

The software can evaluate federal, state, and local government projects for both new and existing buildings.

BLCC also contains a module for evaluating non-profit and for-profit projects in the private sector.

While the BLCC programs are oriented toward building-related decisions, they can be used to evaluate alternative designs for almost any project type in which higher capital investment costs result in lower future operating-related costs.

Analyze Energy and Water Conservation

BLCC5 is programmed in Java with an XML file format. The user's guide is part of the BLCC5 Help system. BLCC version 5.3-07 contains the following six modules:

  • FEMP Analysis, Energy Project for energy and water conservation and renewable energy projects under the FEMP rules based on 10 CFR 436;
  • Federal Analysis, Financed Project for federal projects financed through Energy Savings Performance Contracts (ESPC) or Utility Energy Services Contracts (UESC) as authorized by Executive Order 13123 (6/99);
  • OMB Analysis, Projects subject to OMB Circular A-94 for non-energy, federal government construction projects, but not water resource projects;
  • MILCON Analysis, Energy Project for energy and water conservation and renewable energy projects in military construction;
  • MILCON Analysis, ECIP Project for energy and water conservation projects under the Energy Conservation Investment Program (ECIP); and
  • MILCON Analysis, Non-Energy Project for military construction designs that are not primarily intended for energy or water conservation.
A variety of add-on programs and documents are also available for the Building Life-Cycle Cost programs. EERE Building Life-Cycle Cost Programs

For example:

EERC 1.0-07
(EXE 7.4 MB)
The Energy Escalation Rate Calculator computes an average annual escalation rate for fuel prices from the annual energy price forecasts of the DOE Energy Information Administration. This rate can be used to escalate contract payments in Energy Savings Performance Contracts and Utility Energy Services Contracts when the payments are based on projected annual energy cost savings.
