All Houses, irrespective of window position, have CO2 in surplus of a thousand ppm sooner or later in the course of the two night time monitoring time period. Exactly where Home windows are remaining open up overnight the effects on CO2 degrees are evident with these eight dwellings, displaying significantly reduce intervals previously mentioned one thousand ppm. Within the sub-established wherever Home windows are forever closed, the trickle ventilators open problem reveals a small enhancement in overall performance, but CO2 ranges are in excess of 1000 ppm for a significant portion with the overnight period.
