Five members of Congress from Arizona are seeking to postpone the implementation of new energy efficiency standards for central air conditioners and heat pumps.

An HVAC solution was the headliner for an event on Feb. 19 at a 121-year-old building in the nation’s capital named after one of America’s greatest composer-musicians. The event at Duke Ellington School of the Arts demonstrated how stepping beyond traditional non-inverter HVAC systems can preserve a building’s historical architecture, enhance energy efficiencies, minimize noise, and earn design-award accolades.

The building, which opened in September, features energy-saving qualities that include insulated walls, occupancy sensors for lighting, and high-efficiency HVAC and boilers.
