A congregation's decision to weatherize their place of worship isn't a decision made quickly.  Even with all of the benefits, there are numerous complexities to be considered, such as initial cost and potential disturbance to congregation and community activities.  Below are stories of those who have made the leap

South Plains Presbyterian Church, Keswick, VA

This 125 member congregation in Keswick, Virginia recently replaced the antiquated oil furnace in their historic (1819) sanctuary with a new high efficiency HVAC system. Heat is provided by a pilotless ignition high-efficiency propane furnace, while cooling is provided by a top-rated EnergyStar AC unit. Coupled with a programmable thermostat and efficient and attractive ceiling fans mounted high in the sanctuary ceiling, the congregation expects to save hundreds of dollars annually as well as greatly reducing its CO₂ footprint.

Mount Vernon Unitarian Church, Alexandria, VA

Mount Vernon Unitarian Church is blazing the trail for faith-based leadership in conserving energy. Last November they broke ground for the installation of a solar-geothermal heating and cooling system for their Meeting House. Once complete in May 2011, they will be the first "net-zero" congregation in Virginia, meaning that they draw no electricity from the power grid.  The church has also achieved its own wildlife designation, and it is committed to composting biodegradable leftover food from church events.  Read more about their conservation efforts here.
