The Enprova Energy Survey App has been designed to enable surveys to be performed on residential properties. The App provides surveyors with the capability to record Floor Area, Individual Room Area, Heat Loss Calculations, Wall Areas, Roof Area, Roof Light Area, Current Heating Bill Information, Heat Analysis Information, and apply Heat Loss Calculations. The survey information is output to a Enprova portal allowing improvements to be applied including applicable grants which is then used to produce a detailed report for the property owner to review.
