Filming, April Temperatures & Power

It’s nice to feel some bite in the air in the morning now (when we step outside), and also to see the outside temperature monitor start dipping lower and lower each night. Autumn is definitely beginning and winter is not far away. The reading dropped to 13.59 degrees C this morning before sunrise, while we were enjoying comfortable 21-23 inside. Now is the time of year that we start to appreciate building higher than Code, and we’ll start to close up the windows and revert back to rely primarily on our balanced heat-exchanged ventilation system.

We have filming again on Friday for the Living Green TV Show, due to air later this year, so we’re adding some final touches to the home. When that is complete we will announce some more open home dates.

We’ve also plotted all the energy consumption and production (import and export), and are showing a nice gap proving we are definitely positive energy. The below graph has the import in blue, and export in red.

The first six months we were charging an electric vehicle, however it does not seem to have made a significant difference. Interesting is that our consumption is very flat through the year, as we haven’t used any dedicated heating (an occasional wood fire, more for ambience), so the extra power will be more lighting during the shorter days and more use of the dryer. I’m keen to do some digging around and see the variation between summer and winter for homes in our area which rely on heat-pumps to heat their homes.

We have also just changed over to Ecotricity, and their service has been amazing. They come highly recommended.

Open Home & Sensor Results

Our next public open home will be this Sunday the 11th of October, 1-3pm.

Tours starting at 1:15pm and 2:15pm. Please RSVP to hello@idealhouse.org.

We will post additional dates for the next couple of months soon.

We have had our sensors up and running now for a couple of months, and it’s great to see the data for what we’re experiencing in the home. I’m amazed by the low humidity levels compared to outside, and the fact that our Zehnder balanced heat-exchange ventilation system takes care of additional moisture from the bathrooms without any additional (direct) extraction. Humidity primarily is sitting between 50-60% inside, and 70-90% outside.

Temperatures as you would expect are sitting primarily between 20 & 25 degrees C, with some variations when we’re away, or when we occasionally lit the fire over winter. Apart from that, there is no additional heating in the home. The garage is interesting (blue line), as it’s sitting nicely between inside (the thermal envelope) and outside – a good transition area.

Open day Sat 25th April 11am-1pm

We have had a range of tours and visits over the last couple of months from interested parties, and we will post more opening dates on the blog.

Next open day Saturday 25th April, 11am – 1pm.

Please write to hello@idealhouse.org to register your interest and for the address.

We’ve had our first cold snap of autumn, and the home is performing beautifully – continuing to hold up above 20 degrees C with no additional heating. We are looking forward to spending our first full winter in the home, and showing it off at a time when you can really experience the performance.
