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….
‘Why SPECIFICATIONS are still important…..’ 🤓
We like No. 11: “By being clear and concise and containing all the information, it SAVES the Project Team, the Client and the Contractor TIME + MONEY by providing ANSWERS to many of the on-site construction questions”.
Variety is the spice of life…
– Presented Sketch Designs of a new Project,
– Coordinated works of a current project on site,
– Design coordination,
– & drawing up survey plans and elevations based on survey notes of an existing dwelling house.
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.
Day 2 – Nearly Zero Energy Building Forum at the Clayton Hotel, Wexford.
Day 1 – Nearly Zero Energy Building Forum in Wexford County Buildings.
