Dwellings Energy Assessment Procedure (DEAP)
The DEAP manual describes the Dwelling Energy Assessment Procedure (DEAP), which is the Irish official procedure for calculating and assessing the energy performance of dwellings. DEAP calculates the energy performance of new and existing dwellings. The procedure takes account of the energy required for space heating, ventilation, water heating and lighting, less savings from energy generation technologies. For standardised occupancy, it calculates annual values of delivered energy consumption, primary energy consumption, carbon dioxide emissions and costs, both totals and per square metre of total floor area of the dwelling.
The DEAP methodology for heat pumps has been updated (FEB 2016) and is available here
The Introduction to DEAP for Professionals describes the principles of DEAP for those involved in building research or the design, construction or retrofit of dwellings. This document is also useful for anyone wishing to understand the technical basis for BER certificates and Advisory Reports.
