The Guiding Principles for Sustainable Federal Buildings: New Construction and Modernization

  • HVAC systems must be commissioned, and integrative design principles should be employed.
  • A 30% reduction in energy use compared to ASHRAE Standard 90.1 for new construction necessitates HVAC best practices and use of energy efficient lighting products.
  • Thermal comfort is also addressed, requiring that facilities meet both ASHRAE Standard 55 and either 62.1 or 62.2.
  • A moisture control strategy must also be established to prevent building damage and mold contamination.
  • Refrigerants must not be ozone-depleting or have high global warming potential (GWP).

Determining Compliance with the Guiding Principles for Sustainable Federal Buildings

Relation to HVAC: employ integrative design, commissioning (HVAC and controls), energy efficiency, thermal comfort

The Guiding Principles for Sustainable Federal Buildings: Existing Buildings

  • At least 15% of each agency’s existing building facilities and building leases (above 5,000 gsf) must comply with the Guiding Principles for Sustainable Federal Buildings for Existing Buidlings by 2025, resulting in the necessity for agencies to upgrade portions of their building stock.
  • Building recommissioning must have been performed within two years prior to reporting a building as meeting the Guiding Principles.
  • Thermal comfort, ventilation, and moisture requirements are consistent with those for new construction.

Executive Order 13693 (2015)

Planning for Federal Sustainability in the Next Decade

Executive Order (EO) 13693 specifically involves HVAC components in a number of sustainability performance goals it established. For example, Section 3 sets minimum percentages for the amount of building electric energy that should be clean energy, including renewable electric energy and alternative energy. Managing existing building systems to reduce their consumption of energy and associated maintenance costs to create sustainable building communities is also laid forth.

Relation to HVAC: energy efficiency, greenhouse gas emissions – purchased electricity consumption, Guiding Principles for Existing Buildings.

Energy Independence and Security Act (2007)

EISA 2007 established energy management goals and requirements, of which a sustainable lighting strategy is necessary, for federal buildings. It established a 30% energy consumption goal per gross square foot of federal space. Efficiency standards for packaged HVAC equipment and electric motors are prescribed.

Relation to HVAC: energy efficiency, packaged equipment

Energy Policy Act of 2005

The Energy Policy Act of 2005 (EPAct 2005) amends EPAct 1992 and establishes a number of energy management goals for federal facilities involving components of a sustainable lighting system. Each agency is required to incorporate energy efficiency criteria in “all procurements involving energy consuming products and systems.” EPAct 2005 also directs new federal buildings to be designed 30% below the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) or International Energy Code standards. Efficiency must come without sacrifice in performance, and selection of high performance equipment is recommended, with the Act providing guidance on minimum energy efficiency ratios (EERs).

Relation to HVAC: energy management, energy-efficient lighting procurement, energy efficiency

National Energy Consumption Policy Act (1978)

The National Energy Consumption Policy Act (NECPA) serves as the underlying authority for federal energy management goals and has been regularly updated and amended by subsequent policies such as EPAct 1992, EPAct 2005, and EISA 2007. Energy reduction goals are set and amended as new best practices arise.
