February 2019 edit

Tasks

• Confirm air inlets with ventilation company
• Confirm how the shutter covers/boxes are to be made to work with these air inlets (with carpenter and ventilation folks)
• Shutter covers made and delivered to home
• Air inlets fitted
• Electricians connect all the shutter motors to the switches [80% done, some materials missing]
• Shutter covers/boxes fitted

We have a pretty intense exhaust system set up in the house to ensure that we are constantly renewing the air in the house and also removing any unnecessary smells/stagnant air/dust in the air and for relative humidity control.

In order to balance out the air we are pushing out of the house, there needs to be a way for air to move into the house, otherwise there will be a depressurisation and the exhausts will be working to suck air out at half of their usual effectiveness.

There are two ways to do this:

• Relying on people opening windows
• Air inlets

The proposal from our ventilation contact was originally to build air inlets into the walls, but we were able to discuss various options and his latest proposal is air inlets in the wooden structures housing the shutters on every window.

Open Questions

• What are the fire safety implications of these inlets?
• Are they one-way only valves?
• Do they have noise insulation?
• Why do we have to have them on every window?

Questions have been put to them for discussion.

Resolved these issues!

The air inlets are two-way, but prevent uncontrolled air intake in the case of blustery days.

They are fully noise insulated and we mediated between the carpenter and the ventilation folks to reach a solution for installing them which will be very minimally visible and still ensure the window casings can be easily removed for access to the shutters.

There will be 10 throughout the entire house, not in every room and not on every window.

These are currently being added to the window frames/shutter boxes.

OK! The shutter boxes are now all made and awaiting for the air inlets to be installed.

As soon as this is done and the electrician has finished connecting all the shutter motors to the switches , the carpenter can get all the shutter boxes in place 👍

Emailed the ventilation folks today to schedule this in asap.

Called them again today, they're going to come to get this done on Tuesday (12-Mar-2019).

Air inlets finally fitted yesterday. Electricians completed their part last week.
