Not exact matches

Despite increasing standards of insulation and airtightness, housing developers face few requirements to provide better ventilation and indoor air quality for new home buyers — beyond knocking extra holes in walls.

When it came to upgrading an old stone - walled building to the Enerphit standard — with all the inherent challenges such an upgrade poses for energy, airtightness and moisture — who better to have as your client and defacto site manager than a professor of physics?

The smaller the airtightness figure the better.

So it's refreshing to find that the designer of this contemporary Dublin home put so much attention on insulation, airtightness and indoor air quality — as well as good looks.

Building retrofit technologies and thermal bridging pioneered by the Princeton House Doctors at the Twin Rivers Retrofit between 1976 - 1979, established that insulation and airtightness gave far better payback periods than active systems like seasonal storage tanks.

What's the best way to ensure you hit your airtightness goal?

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.

There's also considerable room for improvement on airtightness levels required in Part L1A, currently standing at 10m3 / hr / m2 compared to a margin - ally better 7m3 / hr / m2 in Ireland.

If a builder achieves an airtightness level of 5 cubic metres of air leakage per hour, or better, and chooses so called «natural» ventilation, he must increase the equivalent area of background ventilation by 40 %.

Despite this, the building achieved an airtightness of 0.39 air changes per hour, well within the passive house standard of 0.6.

It is essential, however, that the house has been properly designed in PHPP and then well - executed on - site achieving the required levels of airtightness and low thermal bridging.

Higher energy standards during building and airtightness testing are two key factors in achieving better homes across Europe.

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.

It has been suggested that by moving the ceiling air barrier and thermal barrier to the plane of the roof, that better building airtightness can be more easily achieved, and that the elimination of heat gain to the attic air distribution ducts would more than offset the additional heat gain caused by not venting the attic.

On phase two however, the airtightness strategy was exemplary, and delivered results as low as 0.29 ACH — among the best results ever achieved in this country — ably assisted by experienced airtightness contractor Roman Szypura of Clioma House.

«The objective for the phase two houses,» says Stuart, «was to build better houses by focusing on integrating a designed ventilation system, a high degree of airtightness, minimal thermal bridging and high thermal performance.»

The Sustainable Energy Authority of Ireland has announced a new $ 5million deep retrofit pilot programme for 2017 projects to upgrade inefficient buildings to an A3 rating or better — with a particular emphasis on ventilation, airtightness, thermal bridging, interstitial condensation and preventing overheating.

The building's annual heat demand is just 9 kWh / m2 / yr, well inside the passive house mark of 15, and airtightness is 0.4 air changes per hour.

Relying on the purchase of large swaths of subsidized photovoltaic's or complex and expensive heating / cooling systems to reduce the energy signature of a building before using more economical strategies such as efficient appliances, good insulation, windows, and airtightness is widely accepted as a waste of resources (materials and money).

The Home Performance Index is aiming to do just that, gathering and sharing the data on best practice for a full range of indicators from airtightness to lesser known benchmarks on waste management, sustainable procurement, ecology, water, and embodied carbon.
