Week 49, Day 5:
- At the moment a lot of the progress doesn’t show up in the pictures – there’s quite a lot of “soft” configuration of the lighting, security and heating systems where it doesn’t look like anything has changed
- Since there’s a duct heater on the MVHR Supply to the house, the ducts down-stream of this need to be insulated to keep the heat inside the ducts so the air is still warm when it gets to the far end
- The “hot” water supply to the duct heater is coming from the Ground Source Heat Pump and is therefore going to be warm rather than hot with most likely a relatively small effect on the air temperature
- The small-bore plastic heating ducts are naturally better insulated than steel ducting and these were intentionally enclosed in the inter-floor insulation (more intended for acoustic rather than thermal purposes) so it’s really just the steel ducts and plenums in the Plant Room that need insulating
- More work commissioning the lighting systems
- Now all of the internal downlights and wall lights are installed and working, with just the LED strip lights and most of the outside lights to go
- In the evening I completed the basic KNX programming so that the ceiling-mounted PIR switches in the bathrooms and hallways / landings control the relevant lights and the relatively small number of wall switches control the main lights in each room
- The Up/Down light on the Balcony (a Nordlux Canto Maxi) has a pair of (allegedly) dimmable 5W GU10 LED bulbs controlled by an Aurora AU-DATR400 mains-voltage DALI dimmer. Compared to the excellent dimming behaviour of the internal lights with their separate DALI dimmers this combination isn’t anything like as good. More investigation required.
