Tool Version
Building Assessment Tool (BAT) 1.0 The BAT provides a means to collect, validate, and update the information needed for auditors to conduct Energy and Facility Condition Assessments in an organized database structure.
Building Life-Cycle Cost (BLCC) 5.3-19 The National Institute of Standards and Technology (NIST) developed the Building Life Cycle Cost (BLCC) Programs to provide computational support for the analysis of capital investments in buildings.
Energy Escalation Rate Calculator (EERC) 2.0-19 This tool computes an average annual escalation rate for a specified time period, which can be used as an escalation rate for contract payments in energy savings performance contracts and utility energy services contracts.
ENERGY STAR Portfolio Manager® Online EPA's online energy management and tracking tool enables you to measure and track the energy and water performance of any building over time.
EnergyPlus™ 9.0.1 EnergyPlus™ is a whole building energy simulation program that engineers, architects, and researchers use to model both energy consumption and water use in buildings.
Facility Energy Decision System (FEDS) 8.0 The Facility Energy Decision System (FEDS) is an easy-to-use building energy efficiency software tool that quickly and objectively identifies energy efficiency improvements that maximize life-cycle savings.
Hourly Analysis Program (HAP) 5.1 HAP is a system design tool and an energy simulation tool in one package.
Life-Cycle Energy Performance Framework for Cities 1.0 The Framework provides policymakers a tool to look across building codes, incentive and utility programs, and post-occupancy/operations policies, to identify potential policies and triggers that can be deployed to impact building energy use.
Sustainable Facilities Tool (SFTool) Online The Sustainable Facilities Tool ( is an interactive website that shows users how to build, buy, and operate green.
TRACE 700 6.3 TRACE 700 helps you compare the energy and economic impact of building-related selections such as architectural features, HVAC systems, HVAC equipment, building utilization or scheduling, and financial options.
