Green Building Episode 3: Concrete Slab Insulation for Energy Efficiency
This short film is Episode 3 in Peckham Architecture’s 11-part documentary series on how to construct a green building for energy efficiency and reduced carbon footprint. This episode shows how concrete slab insulation can save energy in a green building. Peckham Architecture’s LEED Platinum home headquarters is net-positive, meaning it produces more electricity than it consumes. We accomplished this in part with proper insulation of thermal bridges, or areas where energy typically escapes: concrete slab foundation, walls, doors, windows, ceiling and roof. To reduce heat transfer, we installed extruded polystyrene foam insulation beneath the concrete slab foundation.
