Sentences with phrase «space heating demand»

This enables a result for specific space heat demand to be calculated quickly using default values, potentially saving significant time.

For instance they make different assumptions about thermal comfort levels, and this profoundly effects the assumptions about space heating demand.

This involves ensuring the individual components of the building fabric and ventilation system are certified, rather than aiming for an overall space heating demand figure.

Often financed via energy service companies (ESCos), district heating systems tend not to become less viable in very energy efficient buildings, given that the low space heating demand means smaller bills payable to the ESCos

While the results of ongoing monitoring were unavailable for this article, a quick analysis by Passive House Plus suggests that a typical 43.7 sqm apartment at Rochestown House would be using just under 1100 kWh of energy for space heating annually, based on the calculated space heating demand of 25 kWh / m2 / yr.

When MosArt uses the term Passive House, we refer strictly to the standards and definitions set out by the Passivhaus Institut in Germany, including maximum space heating demand of 15kWh / m2 / year, an airtightness level of 0.6 air changes per hour measured at 50 Pascal and a maximum primary energy use of 120 kWh / m2 / year.

Building type: 350 sqm detached two - storey wide cavity masonry build Location: County Galway Completion date: June 2013 Passive house certification: N / A Space heating demand (PHPP): 36 kWh / m2 / yr Heat load (PHPP): 16 W / m2 Primary energy demand (PHPP): 85 kWh / m2 / yr Airtightness: 0.48 ACH at 50 Pascals.

Energy use for 2013 shows an actual space heating demand of 27 kWh / m2 / yr, compared with 24 kWh / m2 / yr as modelled — both values based on the PHPP floor area of 125sqm.

At Rochestown House, the calculated space heating demand of 25 kWh / m2 / yr is accompanied with a domestic hot water demand of 32 kWh / m2 / yr.

It demands airtightness of 1.0 air changes per hour and space heating demand of 25kWh / m2 / yr (as opposed to 0.6 air changes per hour and 15 kWh / m2 / yr for the original passive house standard).

The aim was to get to around 40 - 45 kWh / m ² / yr of space heating demand, but with the missed airtightness target the team couldn't get that low in all the units — the average is about 65 kWh / m ² / yr.

And with airtightness of 0.6 ACH, space heating demand of 13 kWh / m2 / yr and a heat load of 9 W / m2, it ticks all the key passive house boxes too.

Enerphit refurbishment with single - storey side and rear extension Location: Rathgar, Dublin Completion date: July 2015 Enerphit certification: pending BER Before: D1 (251 kWh / m2 / yr) After: A2 BER (43.05 kWh / m2 / yr) Space heating demand (PHPP): 22 kWh / m2 / yr Heat load (PHPP): 13 W / m2 Primary energy demand (PHPP): 78 kWh / m2 / yr Airtightness (at 50 Pascals): 0.99 ACH Walls Before: 215 mm solid brick walls with no insulation.

The building achieved an airtightness result of 0.43 ACH, comfortably within the target for passive buildings, and has a space heating demand of 15 kWh / m2 / yr.

The Annual Heating Worksheet gives the space heating demand (kWh / m2a) using annual climate data and also includes a heat balance graph.

Like the Knox, Maine, Passivhaus, the NewenHouse is wrapped in a jacket of cellulose — and similarly comes in well under the specific space heating demand.

The most impressive bit about getting the space heating demand so low, outside of achieving affordability in a difficult climate, was leaving wiggle room for future additions or modifications.
