Part L3: New Dwellings
Design considerations to meet compliance
The principal requirement of the new Part L is for a 40% reduction in energy demand and carbon dioxide emissions associated with heating, domestic hot water and lighting.
For new Dwellings,designers will calculate compliance using DEAP, the Dwelling Energy Assessment Procedure software package created as a result of Ireland’s obligations under the EPBD.
In order to achieve higher ratings developers will be required to design dwellings which go above the minimum standards and which include energy efficient features such as condensing boilers, passive solar design, energy efficient glazing, increased insulation levels, renewable energy technologies, etc
