EETWeb.com – Making pneumatic thermostats energy efficient

An electronic retrofit for pneumatically controlled heating and cooling systems shows how to bring old buildings into the 21st century.

In the last decade or so, owners of commercial buildings have relied on building automation systems (BAS) to minimize energy use, with the biggest savings generated from better control over HVAC systems.
