Building Envelope Solutions


Building Envelope Solutions (BES) delivers world class energy efficiency solutions to corporate and government buildings.

​Energy saving measures can come from many different areas. BES drives down energy consumption by sealing gaps in the exterior of the building that are allowing uncontrolled flow of air through cracks, holes and gaps in the exterior of the building.

Implementation of building envelope measures assist with over all building performance including energy savings and carbon reduction. Building envelope measures also provide benefits in the health and safety of the people utilizing the facility.


Through its industry leading measurement and verification techniques and highly efficient delivery teams, BES has become the leading provider of Building Envelope Solutions to the ESCO market in the United States. BES personnel and staff are located in local regions across the U.S. to ensure rapid delivery of auditing and development assistance, as well as self-performed implementation.






The infrared imagery above demonstrates the immediate impact of BES door weatherization. The example shows the inside of an Elmbrook School District gymnasium door, used as an emergency exit leading to the outside environment.

​The "Before" picture on the left does not utilize door weatherization, therefor the infrared camera measures a 37.8⁰ F(outdoor temperature 26.2⁰ F). The same measurement was taken two hours later after BES door stripping was applied. A significant and immediate difference is achieved as demonstrated in the "After" image; it demonstrates an IR spot of 51.4⁰ F (outdoor temp 25.4⁰ F), providing a 13.6⁰ F increase in temperature.
