An ABUILD Home is a comfortable, A-rated, energy efficient building that complies with the current   Building Regulations. We work with the Architect / Builder to design & construct new buildings, by       adopting practical cost effective measures that suit the Owner.  

ABUILD will work with the architect and builder/selfbuilder to construct an A-rated Low Energy Building in compliance  with Part L of the Building Regulations. 

  It is important that the Builder understands the extra work and cost that is now involved in building an A3 and A2-rated (NZEB) home. Give us a call if you are planning to build your dream home.

    We carry out individual services and can arrange Low Cost package deals for several services.

       

                                              Before Construction 


  Building Specifications / DEAP Report

Building Control insist that the Part L Specification Report is included with the commencement notice to ensure the building design is compliant. 


If you email us your drawings or XML file, we will update the design and publish a more practical, cost effective Part L Report that suits your needs.



   Thermal Bridge Analysis


It is important that insulation in the roof, walls and floor work together to conserve heat, and reduce your building's overall heat load. You must use Acceptable Construction Details (ACDs) from Appendix D or otherwise. 


We offer advice on insulation continuity to reduce thermal bridging and heat loss. We can calculate a Thermal Bridging Factor (<0.08W/mK) to assist with building compliance.

         Air Barrier


 Air tightness needs to be a priority throughout the construction process and a strategy should be adopted from the start.   

 

It is important that you agree on the Air Tightness level from the start as it will influence the ventilation system for Part F Compliance. 


If you email us your drawings, we will design the air barrier membrane and provide you with a supply cost.

Ventilation System  -  Part F Compliance

  


It is important that you have adequate air supply to habitable rooms and extraction from bathrooms / kitchens. Insufficient ventilation can lead to mould growth, condensation damage and unhealthy living conditions.


ABUILD will advise you on the most suitable ventilation system to match your home's airtightness level.

  Renewable Technology

  

A renewable energy source is now required in all new builds in accordance with the Building Regulations (10kWh/m2/yr for thermal or 4kWh/m2/yr electrical).

It is not always clear which systems are more suitable. We will check a combination of systems and advise you on the most cost effective.

ABUILD are proud members of the Renewable Energy Business Network. We offer free consultation to help you choose the most practical renewable technology for Part L compliance.

                                                                                         After Construction


Air Tightness Test

It is now mandatory that an Air Tightness Test is carried out for all new builds to comply with the Building Regulations 1.5.4 Part L.

All domestic new builds should be constructed to a minimum air permeability requirement of 7m³/hr/m² at 50 Pa. The airtightness test must be carried out before the building is habitable in accordance to European Standard EN ISO 9972:2015 - Thermal Performance of Buildings - Fan Pressurization Method B.

ABUILD are NSAI registered Airtightness Testers and our results are used in the Final DEAP Report (L3a) as proof of Part L Compliance. We can even seal up unwanted leaks during the test to help you reach a better air tightness level.

Final BER Certificate

            

Building Control require a Final BER Certificate with Part L Report as proof of Part L Compliance.

The BER Assessor can only publish a Certificate based on the information gathered from the survey and recorded by the homeowner.  

The BER Assessor must publish the certificate and report in an independent manner according to the SEAI Code of Practice.

Building Control will not issue a certificate of completion if the building fails to comply to  Building Regulations. Homeowners/Builders can not occupy or take ownership, if Building Control refuse to add their building to the National Register. It is solely the responsibility of the homeowner / builder that the finished building is compliant.
