Groundwork Denver provides energy assessments to both homes and nonprofit offices by working with residents, tenants and energy advisers to identify and prioritize potential energy improvements.
A home energy assessment can save between $50–$350 a year by identifying simple changes like installing Compact Fluorescent Light (CFL) bulbs to bigger changes like attic insulation.
