'Fabric First' Strategies. Traditional Thick Solid Stone Walls. Eoin O'Keeffe Architects | The Connection of People + their House to a Site

Some ideas + discussions that recently arose with a Client on a Project:

  • Involving the refurbishment of a traditional Irish Farm House, of existing solid wall construction (typically 600mm thick walls) with a proposed small scale new Front Entrance Lobby Extension.
  • A discussion from the viewpoint of Thermal Insulation, Heating, Air Tightness + Building Fabric in the context of thick Solid Stone Walls in a Traditional Irish Farmhouse (and also applicable to Cottages, Period Houses, Out Buildings, etc.)
  • The Project is at Design Stage (Pre-Tender), where options and decisions on construction systems, build ups and specifications will need to be made, so that a co-ordinated set of technical drawings + documents will be ready for issuing for Tender to Building Contractors for pricing.

Q. In real terms, what is the equivalent area of an Air-Tightness Test Result of 7 m3/(hr.m2)?
A. It would be in effect be like having a hole the size of an A4 page in the external wall of a new house ( = cold air in / warm air out). & costing people money.
We attended the ‘BUILD BETTER’ Conference for Residential Compliance & Meeting nZEB in #Waterford on Tuesday.

Hosted by Saint Gobain, Gyproc, Isover & Weber, providing skills, information + discussion with presentation from Jason Horex Saint Gobain, Niall Vaughan CLV, Brian Dempsey WIT + Conor Taaffe Homebond, on:

– Fire Safety for Dwellings (Building Regulation update),
– Sound + Dwelling Acoustics,
– nZEB (near zero energy buildings) + Thermal Bridging,
– Air Tightness,
– Masonry + Rendering.

AIR TIGHTNESS + AIR PERMEABILITY:
– Equivalent area of an Air-Tightness Test Result of 7 m3/(hr.m2) = A4 page size approx. (2011 Building Regulations maximum result)
– Equivalent area of an Air-Tightness Test Result of 5 m3/(hr.m2) = A4 page x 70% size approx. (2019 Building Regulations maximum result)
– Equivalent area of an Air-Tightness Test Result of 3 m3/(hr.m2) = A4 page x 40% size approx. (2019 Building Regulations max. result with MHRV)
– Equivalent area of an Air-Tightness Test Result of 0.6 m3/(hr.m2) = A4 x 9% page size approx. (Passive House Standard)

Overall very informative + a good morning of learning at the Tower Hotel….

What is ‘nZEB’?
‘nZEB’ stands for ‘nearly zero Energy Buildings’ which have a “very high energy performance”.
The “nearly zero or very low amount of energy should be covered to a very significant extent from renewable sources produced on-site or nearby”.

When does nZEB kick-in?

After 31st December 2018 for buildings owned and occupied by public authorities and by 31st December 2020 for all other buildings.
