Part L Compliance
On the 1st March 2014, the Building Control (Amendment) Regulations 2014 were introduced, this has altered the process of building and certifying a residential new-build in Ireland.
As a result, ensuring compliance with Part L “Conservation of Fuel and Energy” of the Building Regulations for new residential buildings is now an essential part of the design and planning process for builders/developers, architects and assigned certifiers.
AE Solutions provide guidance for architects, engineers, builders, assigned certifiers and homeowners on the requirements needed to achieve Part L compliance and ensure the best Building Energy Rating (BER) possible.
This includes:
- Part L Compliance Report
- Provisional BER
- U Value Calculations for building elements
- Air tightness requirements.
- Thermal bridging and ACDs (Approved Construction Details)
- Heating system options (Heat Pumps, Solar thermal, PV systems wood burning stoves).
To achieve Part L Compliance, new builds must achieve the following performance criteria:
- Conformity with maximum average U-Value requirements of building elements ie. walls, roof, floor, doors and windows.
- Maximum Permitted Energy Performance Coefficient (MPEPC) <= 0.40
- Maximum Permitted Carbon Performance Coefficient (MPCPC) <= 0.46
- Air Permeability test ac/h <= 0.35
- Part L renewable technologies contribution = 10kwh/m2/yr (eg. Heat pump, wood burning stove, solar thermal and solar PV)
