Description:

As buildings age, their envelopes can lose efficiency and require upkeep to avoid excessive heating and cooling costs. Recaulking windows is a cheap and cost-effective way to seal up the building and prevent heating/cooling loss, saving anywhere from 3-12% in HVAC costs. Solutions can in also include adding automatic shades or blinds and introducing a vestibule at the entrances of the building to prevent energy losses dependent on the outside temperature. Thermal imaging (see picture) can be used to identify areas of your building particularly prone to energy loss and due for upgrade.

Special Considerations

• The cost of improving your building’s exterior will vary based on the technology chosen. Consult the Department of Energy’s Energy Efficiency in Separate Tenant Spaces Feasibility Study for details on ways to improve your building envelope’s performance.
