FEDS

FEDS logo.

Provides a comprehensive method for quickly and objectively identifying energy improvements that offer maximum savings. FEDS (Facility Energy Decision System) makes assessments and analyzes energy efficiency of single buildings, multiple buildings, or all buildings of an entire facility. It provides an easy-to-use tool for identifying energy efficiency measures, selecting minimum life-cycle costs, determining payback, and enabling users to prioritize retrofit options and compare alternative financing options (site funding, leases, loans, ESPCs). FEDS also evaluates whether decentralization options are economically optimal for central energy plants and thermal loops.

Keywords

single buildings, multibuilding facilities, central energy plants, thermal loops, energy simulation, retrofit opportunities, life cycle costing, emissions impacts, alternative financing

Validation/Testing

N/A

Expertise Required

Minimal using readily available information. Requires two or more hours depending on number of buildings.

Users

Over 1,500

Audience

Energy and facility managers, architects-engineers, utility planners, building technology researchers, educators, federal agencies, and energy consultants.

Input

Location, building types, operating hours, age, square footage, fuels used by facility and energy price data are required. Numerous detailed engineering parameters are optional.

Output

Fuel-neutral analysis with full life-cycle costing of retrofit options (ECMs) for the on-site buildings. Output data includes energy and cost savings, emissions reductions, and a wide range of economic measures.

Computer Platform

PC-compatible, operating Windows NT/2000/XP/Vista.

Programming Language

C

Strengths

Allows but does not require input of engineering parameters. Energy/economic analysis. Models peak demand. Optimizes retrofit opportunities. Performs analysis that meets unique Federal needs. Provides emissions impacts. Accepts an unlimited number of buildings. Considers decentralization for central energy plants and thermal loops. Engineering and economic parameters provided are user adjustable. Flexible operation to meet a variety of needs.

Weaknesses

Not a buildings design tool.
