Higher costs, less benefits - Why the enhanced social housing leasing model is a bad deal

The outgoing Fine Gael government devised an off balance sheet scheme to deliver social housing, but will it deliver value for money? Mel Reynolds crunches the numbers and finds the scheme may almost double the cost compared to a direct build – with no asset left once the lease ends.

The PH+ guides

The PH+ guide to insulating foundations

The PH+ guide to insulating foundations

While understanding wall and roof insulation is relatively straightforward, insulation under the ground floor can be a bit of a mystery by comparison. Not only is it buried in the ground, but there are notoriously tricky spots like the wall-floor junction that need to be detailed and insulated properly. And the design of your foundation often depends on site conditions and the type of structure you’re going to build, too. In this guide, we explain some different ways of insulating one of the most challenging parts of the building envelope.

The PH+ guide to airtightness

Once poorly understood by the mainstream building industry, airtightness is now increasingly seen as one of the most crucial objectives on any building project. Not only is it vital for energy efficiency, it’s also key for thermal comfort and for protecting a building’s structure from dampness and mould. In this comprehensive guide to airtightness, we look at why it’s so important, how exactly it’s measured, and most importantly, how to achieve it on site.
