MY ECO CONSTRUCTION
Russlestown (Nzeb or even passive Standard)
Although this property was issued an A3 Rating it actually performs at a Passive house standard. The owners have occupied the house for a full year and we are able to show all of the Heating and hot water costs to date.
We have considered the rules and formula's applied by the current BER that gave this property A3 rated. Heating season duration, target room temperatures, hot water usage per person applied from M2 of building and outside average temperatures.
