Hancock’s HEAT Energy Audit Tool is an energy auditing app for the iPad that energy models single family and manufactured homes. HEAT works offline, disconnected from the internet, enabling you to weatherize in remote areas. It holds the data until you are connected to the internet again, and then syncs with an online workflow system. HEAT is approved by the Department of Energy for full house energy audits, but can also be used in “quick audit” mode. Take photos with mobile devices or cameras, these photos are integrated into the electronic audit tool and viewed through an online gallery.
