This guide to ventilation building regulations is published by the Dept of the Environment.


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 version 3.2.1 calculates the energy performance of new and existing dwellings. The procedure takes account of the energy required for space heating, ventilation systems, 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. 

Please note : Building Regulations stipulate minimum standards and not best practise.
