Osprey Building Performance

Osprey Building Performance designs, tests, and balances commercial and residential buildings' HVAC systems.


Air Balancing​

An air balance measures the performance of a commercial or residential HVAC system and adjusts to provide the occupants a comfortably conditioned space.

​Combustion Safety Testing (CST)

CST testing ensures open combustion appliances (gas water heaters, gas stoves, and gas furnaces) are not causing unhealthy or hazardous conditions in residential or commercial buildings.

​Duct Leakage Test

Leakage from ducts can account for up to 20% of the energy losses in a residential or commercial building. Duct leakage tests can determine the amount and location the leakage is occurring.​

​Infrared Diagnostics

Infrared imaging creates pictures showing the temperatures of surfaces. It is used in diagnosing temperature issues in a building’s energy performance.

​​Manual J, D and S

Manual J, D and S are standards and protocols for proper design and installation of HVAC equipment and duct work. They model a building for energy efficiently by calculating equipment, duct sizing and system load calculations. These standards are part of the residential IECC and the Mechanical code.


The REScheck assists builders, designers, and contractors in determining whether new homes, additions, and alterations meet the requirements of the IECC or state energy codes.
