Recruiting group members
We’ve had a request from a busy charity that has been paired with one of our Engineers without Borders volunteers. They’d like us to suggest words they can send out to help them recruit the members for their small group. Charity volunteers tend to be passionate and dedicated, but over-stretched, and it can be tricky…

How to run sessions
We’ve trained our first group leaders and engineers, and they are ready to run sessions. If you’re curious to see more detail of what the sessions contain, you can find the session schedules and supporting materials here: Materials – HeatHack We’re still finishing off some elements of it, but they’ll be done in time for…

A mid-price fix for TRVs
Thermostatic radiator valves cause all kinds of issues in community buildings – users disagree about the settings, wrench them on and off, and then they break. It doesn’t help that most people think that they higher they are set, the faster the space will heat up. That’s not true. They just either let the hot…

Off they go
The stock of thermal monitors has been growing, but now it’s time to send them out to those engineers in the first group who have a venue and group who want to improve the comfort and carbon footprint of their building. Not all the boxes look the same. Firstly, there are sensors – with the…

A game, sort of
It’s important in our group sessions that everyone participates. Games are a very common way to make activities more engaging and ensure this happens. For our second session, we’ve devised a sort of a game. There’s no winners and no losers, and no real sense of knowing how the group has done, but it has cards…

Sensor Accuracy
We use inexpensive DHT22 temperature and relative humidity sensors, so we don’t assume they are reliable. Instead we compare them with each other and with the most common off-the-shelf devices we see in use, Lascar EL-WIN-USB loggers. Our Lascars claim accuracy of 2.25%RH in the range 20-80% RH. Years back, we had some engineering students…

A welcome to Eco-Congregations
Last night we spoke to Eco-Congregation Scotland members about our programme. Eco-Congregation has been very supportive of what we do because it complements and deepens what they are themselves able to offer. For those who were unable to make it, here are the slides we used.

Covid ventilation measures
We’re having many conversations with community groups as we match them to engineers, and some of them have raised an issue to do with Covid. They know that more ventilation means more heat loss, and that draughts make people much less comfortable. They don’t want to risk anyone’s health, so they are asking what the…
