    This report summarises the technical results and monitoring data from the Elm Tree Mews field trial carried out by the Centre for the Built Environment at Leeds Metropolitan University on behalf of the Joseph Rowntree Foundation (JRF) and Joseph Rowntree Housing Trust (JRHT). The Elm Tree Mews Field Trial research programme was funded under JRF project No. 805319.

    This report details the technical data from fabric performance tests carried out on the completed dwellings, site
    observations and photographic records of the construction process and an analysis of available site documentation and drawings. Performance testing included pressure tests, a coheating test, thermal imaging, temperature and air flow measurements and heat flux measurements. A design retrospective of those aspects of the design and construction process related to energy performance was undertaken by an assessment of available documentation and through a series of semi-structured interviews with key individuals involved with the development.

    The report also contains the results of 12 months in-use monitoring of the occupied dwellings and data on the performance of the communal heat pump system.

    The report contains some interesting heat loss photos and observations on the design and build of a timber framed flats development.

    Thanks Triassic, a very interesting read.

    Did the participants feel a sense of failure or that they'd done a "pretty good job" I wonder? Classic mistakes like confusing (deliberately or not) mid-pane u values over whole window u values.

    The residents' views were very interesting and the observation that "home" should be a place where you feel in control, and to what extent they felt they lacked that control.

    Some of the issues here are frightening (timber frame not put up correctly to support loads) and some unsurprising (lack of care over air tightness). The TI images as ever are illuminating especially the effect of the wire for an outside light!

    Wow, what a travesty. I can't believe how bad the airtightness test results were. And talk about a massively over-engineered set of systems. Building timber-frame multi-unit dwellings is standard practice over here and they are airtight and comfortable. If the Elm Mews had just used sprayfoam insulation rather than the mish-mash of fibre and cellulose that would have solved most of the issues. And why the heck don't UK buildings have basements? That would have solved the lack of storage space issue. I still can't believe that you guys insist on trickle vents too!

    Basements is an issue. We don't, because we don't. Trying to get it through BC is difficult enough and then you have to find someone who actually knows how to do it properly is next to impossible. No experience & fear. I must say though, my last plot had a very high water table.

    I have a couple of relatives near here with basements. I'm also pretty sure that on my plot a basement would flood or at least be horribly damp without enormous care; we've had water up to the front door once and we're near a soggy cemetery and minor river.

    Water is the big problem with basements for much of the housing stock in the UK, I think. We already have far, far too many houses built on, or near, flood plains. Most of London is a good example, as are a lot of the big housing conurbations built in the past 100 years.

    My new house build is only "just" outside the 1/100 year flood boundary and I couldn't have a basement as I have a minimum finished floor level stipulation on my planning permission as a flood prevention measure.
