Sentences with phrase «requires airtightness»

In 2006, the International Residential Code tightened up the language to require walls to be sealed, and as of 2009, the IECC requires airtightness testing.

The primary reason for requiring airtightness in buildings has nothing to do with energy efficiency or occupant comfort, writes Helen Brown, head of building physics at Encraft — it's for the protection of the building fabric.

Not exact matches

Jobs: Very low energy and Passive House buildings require increased attention to enclosure construction and the installation of insulation, airtightness and high quality windows.

Learn how to integrate more insulation, airtightness strategies, strategically placed windows, and other common - sense measures to reduce the heating demand required for your next project by 80 %.

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.

Airtightness of buildings, for example, has increased because many building codes now require testing.

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).

«You have flat roof sections and a basement, you have a lot of floor cassettes that you need to incorporate into your airtightness design... This required planning.

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.

Difficult to say, but achieving the required level of airtightness is probably the most challenging aspect.

It is typically much easier to achieve the required level of airtightness when using a system - builder (whether concrete or timber frame), where most of the construction (including fitting and sealing of windows) is carried out in a controlled factory environment.

He found however that the detailing required to ensure airtightness and design away thermal bridges was a lot trickier than it would have been with a timber frame.

Achieving airtightness required a lot of forethought and effort too.

This means that the building fabric must achieve required levels of thermal insulation and airtightness, among other factors, to ensure a maximum space heating and cooling energy demand isn't exceeded.

This is in part associated with balancing the less than optimal volume - to - floor area of the overall design, and the high spec required to manage airtightness.
