STEM for This Old House of Worship


houses of worship



STEM stands for Savings Through Energy Management, a 15-hour program for congregations that teaches the skills needed to reduce energy consumption in their homes and houses of worship.


The STEM program covers all building energy systems, heating, lighting, ventilation and air conditioning as well as the building envelope and appliances. Participants learn to use professional equipment to test and measure the components of their buildings. They also learn how to calculate the energy and fuel to be saved by implementing sound practices. The program also includes information on utility rebates.


STEM is usually taught in 5 three-hour sessions, with each session meeting in a different house of worship. At least 5 and as many as 10 congregations join in the training.


STEM for This Old House of Worship is available exclusively from Wilson Educational Services, Inc. Call 203-250-1501 or email
