W. L. Gary Brings Proven Energy Efficiency Solution to Customers through New Partnership with Transformative Wave

W. L. Gary Company, Inc., a MSCA GreenSTAR contractor in Washington, DC, is proud to announce that they are officially an Affiliate Partner of Transformative Wave, the developer of the CATALYST, North American’s leading rooftop unit (RTU) retrofit product.  As an Affiliate Partner of Transformative Wave, W. L. Gary Company is a certified reseller and installer of CATALYST in the Washington Metropolitan area.

The CATALYST is a complete HVAC energy efficiency upgrade and retrofit kit that can be installed on currently operational RTUs to reduce HVAC energy usage by 25 to 50%. A sustainable alternative to expensive RTU replacement, the CATALYST assures proper ventilation, maximizes the use of outside air for free cooling beyond standard economizer logic, and reduces fan energy use by an average of 69%.

The CATALYST was part of a two year study commissioned by the U.S. Department of Energy (DOE) through Pacific Northwest National Laboratory (PNNL).  The CATALYST was installed on 66 existing RTUs at different building types in 4 different climate zones.  The field trials showed the CATALYST produced an average savings of 57 percent.  (Read the full study here.)
