The solar resource in Temperate Maritime Climates (TMC) can make a significant contribution to space heating demand given the relatively long space heating season, but is this at the cost of summer overheating? This paper reviews the recorded performance of the certified passive houses with contemporaneous houses built to the minimum building regulations in Northern Ireland. The metrics being gathered at five-minute intervals for the houses are analysed:a. occupancy profileb. indoor air temperaturec. indoor relative humidityd. indoor carbon dioxide concentrationse. outdoor temperaturef. outdoor relative humidityg. wind speedh. barometric pressurei. energy consumptionIn addition “soft” data was also gathered on the inhabitants’ perception of indoor air quality, comfort levels, heating costs etc. for both the passive and non-passive houses.Results & Conclusions. The key metrics are reported upon. In addition to the higher recorded temperatures of the passive houses, it is also seen that the average carbon dioxide concentrations are more uniform in the passive houses compared with the houses complying with the minimum building regulations. Further investigation is needed, however the possibility of high CO2 readings due to insufficient ventilation (compared with the forced ventilation system of passive houses) is targeted for further investigation as part of the ongoing monitoring project.
