SWAP Season 3 Recommendations

Throughout the four-day Better Buildings Challenge SWAP, the energy teams from Atlanta and Boston found several opportunities to help its counterpart save energy throughout its city. Read more about what the teams learned from each other, and take away a few energy savings tips from the experts in Atlanta and Boston.

  • Add an additional pane of glass to historic, single-pane windows for an extra layer of insulation.
  • Limit overhead lighting where natural light provides enough illumination. Add sensors so LED lights can adjust to natural lighting.
  • Conserve and reuse water in mechanical systems like HVAC (heating and cooling) through low pressure condensate return systems.
  • Utilize two sets of doors at entrances to keep cold or warm air from entering the building.
  • Upgrade HVAC systems to use Variable Frequency Drives.
  • Variable speed drives on smaller fan units help drive efficiency and keep your mechanical systems up and running, mitigating downtime significantly.
  • Maximize solar-array layout with as many panels as possible to ensure optimal energy displacement.
  • Use dimmable lighting fixtures for public street and parking lot lights.
  • Move heat around large facilities with an efficient HVAC system that includes drop ceilings and ventilation routing upward so temperatures stabilize at higher points of the building.
  • Avoid using multiple thermostats in close proximity – can cause heating and cooling simultaneously. If multiple systems, make sure they’re on same setting (i.e.: heating or cooling).
  • Unplug outlets when something is plugged in but not in use.
  • Separate oil from water in auto-garages and recycle the oil with a local recycling program.
