Federal Facilities Are Leveraging Energy and Water Saving Heating and Cooling Technologies

An information resource from the Federal Energy Management Program (FEMP) highlights various heating, ventilation, and air conditioning (HVAC) technologies with demonstrated energy and water savings that have the potential to be more broadly utilized across federal agencies, including:

• Variable air volume ventilation
• Novel dehumidification systems
• Magnetic bearing chiller compressors
• Thermal energy storage
• Geothermal heating and cooling
• Thermosyphon cooler hybrid systems.

These HVAC technologies can be included as energy or water conservation measures to meet energy and water use intensity requirements under Section 432 of the Energy Information and Security Act. Many federal facilities also have specialized HVAC requirements, such as laboratories with high ventilation requirements and data centers with specific low-temperature requirements.

This information resource includes case studies that highlight the potential for federal agencies to explore different types of HVAC technologies that bring greater efficiencies and energy security for mission activities.
