Test used to determine a home's airtightness: a powerful fan is mounted in an exterior door opening and used to pressurize or depressurize the house.

In the backstop house, we modelled all the minimum backstop values for insulation, windows, airtightness and renewable energy and used a gas boiler as the heating source.

At first glance that temperature difference between Part L1A and passive house might not seem much, but when you consider that the latter also ensures warmer surfaces (achieved through better U-values in opaque elements as well as windows), greatly reduced thermal bridges and some 20 times better levels of airtightness, the comfort levels provided by the two approaches are, frankly, worlds apart.

Our next analysis swapped out a tra - ditional boiler for a high - efficiency (COP of 4.44) electric heat pump and, to our surprise, compliance could be achieved for all three house types with just the backstop values for insulation, airtightness and renewable energy (Ireland's regulations for new homesmandate a renewable energy contri - bution of 10 kWh / m2 / yr thermal energy or 4 kWh / m2 / yr from microgeneration).

He points out that in any house, regardless of its level of airtightness, you have to get an adequate supply of fresh air in, and you have to extract the stale, contaminated, moisture - laden air.

Next we modelled our high performance envelope scenario to see what would be required for compliance if using a boiler and found that near passive house levels of insulation and airtightness would be needed for all three house types, with U-values of 0.13 for opaque elements, 1.2 for windows and doors and an airtightness of 1.0 m3 / h / m2).

The building scored an impressive airtightness test result of 0.5 air changes per hour at 50 Pascals — a score that not only blitzes the requirement for Enerphit (the passive house standard for retrofit), but comfortably beats the new build passive house target of 0.6 ACH too.

Though the building wasn't designed as a passive house, careful attention to airtightness using Ampack's range of tapes and membranes, with particular attention paid to key junctions such as windows, chased walls and a counterbattened service void in ceilings, leading to an impressive pressure test result of 0.48 ACH.

But they knew they wanted an oak - framed house built with structural insulated panels (or SIPs, a fairly common and logical way of filling in oak - framed walls and roofs), good U-values, airtightness, and heat recovery ventilation.

Airtightness: 9 of the 15 houses in phase 2 achieved less than 0.534 ACH at 50 Pa, well below the passive house target.

Ultimately all of the forethought and planning proved its worth, and the house got 0.3 air changes per hour on its first airtightness test, and 0.4 on its final test.
