Testing out monitoring kit now that the house is less full of people. All works fine but installation was more organised than expected and all pulse meters are close together in services cupboard. this is a minor problem involving more wiring than expected.
Pulse block for gas meter has vanished so new one on order, and was tricky to get solarimeter into plane of solar array, along with location of external temp and RH so, a few more adjustments to the system will need to be made after the tenant has moved in and settled on furniture locations.
House open for visitors, all systems in and working, house looking good, just a few minor bits to do before hand over. About 30-40 visitors during the day, i would estimate, the services cupboard attracted most interest i would say
Met Romeo from Rotex who was commissioning Rotex unit, Billy the plumber was commissioning Maico unit also so the services cupboard was full.
rotex unit is not that easy to get calibrated, odd in that it doesn’t have a room thermostat.
Possible issue of oversizing of boiler in Rotex, apparently it winds down to 8kW but this is perhaps high given expected heat loss of house.
Shower waste water heat recovery unit in place, discussion about how they may be best used in swimming pool showers where flow of waste water is high but highly dependent on usage of hot water as to payback time…
house very nearly finished now.
A quick visit today to see how the services are connected.
Overall the house is approaching completion, with doors being fitted, skirting boards fitted, final painting coats being applied upstairs and kitchen part-fitted. The position of the electricity meter was under discussion for some time, and has now been fixed under the stairs, it looks to me like the secondary gas and water meters have yet to be positioned and fitted.
The services are in place and largely plumbed in but not finalised yet, i can see heat meters are connected.
Scaffolding has gone.
The porch is structurally complete, with the inner door being the Passivhaus standard, the outer door in keeping with the street.
I visited today with Justin Bere of Bere Architects http://www.bere.co.uk/. The house is pretty much sealed now, save the front door. Most of the plastering has been completed, the outside rendering on the external insulation looks bright and white. The front room at the top now feels noticeably smaller now the internal insulation is complete.
Plasterer agreed that lime plaster can be brittle and damaged easily, due to the slow drying process risk of damage must be higher, can be dented for several days.
Justin pointed out that external brickwork being visible is not a good reason for planners to deny the use of external insulation, especially if the area already has homes that have painted brick or rendered brick on the front facade already.
In the “plant room”, the Maico MVHR system looks big with silencers, heat exchanger and heater battery all helping to fill up the space. The Rotex unit is placed but not plumbed in yet, also looks big.
On Thur 25th Nov the PassivTerrace will be open to visitors 1-4 pm and it will be 10 people at any one time entrance.
The work is now in the final stages towards completion, so it is still possible to see construction and services details.
Please come along: the design team will be on hand to discuss the project with you.
If you are interested please send an e-mail to firstname.lastname@example.org with subject: PassivTerrace Address, you will receive an automated response with the exact address.
On the 3rd November the design team and the tenants met on site to see the work progress. They then moved to Sandwood office to discuss other issues.
By this date the ground floor had been poured and insulated with 250mm insulation to give a U-value of 0.115 w/m2K:
External insulation to rear facade had been placed:
Windows to the front of the house had been placed:
The two remaining windows are due to be delivered next week, so hopefully we’ll have the opportunity to document how they are fitted with the membrane.
