Register for one of eHaus Waikato's Open Construction Days here.
Every 30 minutes we are recording temperatures and humidity in 4 places around the house also outside and another sensor is located in a new house that is on the same subdivision as a comparison. This graph shows the average lowest daily temperatures in the eHaus and then the outside and other new house temperatures.
What is amazing is there is no one living in the eHaus, we have the curtains and blinds closed which reduce the solar thermal gain and apart from a fridge and the MHRV running there is no activity for most of the week. Our villa by the way is now dropping to 12 degrees and we have already had the woodburner going twice!
