MVHR Air Intake Filter Research

I follow a number of green building folks on Twitter and a recent Tweet from Kate de Selincourt alerted me to a research study that is looking at long-term changes in pollution and air quality by analysing MVHR intake filter samples from buildings in different locations. I presume the focus is on particulate pollution since I don’t expect NOx will leave any trace on the filter.

The research is being done by Claire Jamieson at Phi Architecture in conjunction with the Buildings, Energy and Environment Research Group at Nottingham University and the Green Building Store. There’s more information about the study and a sign-up form here.

I think this is a great idea since the filters are collecting the samples anyway and are normally just thrown away. I’m looking forward to seeing the results of the research, which they say will be published annually.

Final EPC Issued

The new Energy Performance Certificate shows the impact of having the solar panels installed and results in the very pleasing score of 100. The only suggested improvement is the installation of a wind turbine (and I’m not going to bother with that).

Band A EPC, Score of 100

The estimated 3-year energy costs are only about £500 lower than for my old house (which was thoroughly average in Band D – but much smaller) but the solar PV is predicted to offset those costs almost completely. The score of 100 indicates that the house will generate as much energy as it consumes (at least for the basic services of heating, lighting and hot water) so the net cost should be zero.
