As electricity supply from renewable sources continues to grow, and electricity grids gradually decarbonise as dirtier fossil fuels are phased out, heating homes with electrical technologies like heat pumps starts to make more sense. And in the mild, temperate climate of Britain and Ireland, air source heat pumps are particularly suitable — especially as new build standards of energy efficiency continue to tighten, meaning new homes need less and less energy to achieve comfortable indoor temperatures. But how do air source heat pumps work, what types are there, and how much do they cost to run? Our in-depth guide attempts...
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.
Cement is responsible for up to 8% of global carbon emissions, and in this guide, sustainable design expert Jay Stuart looks at ways to minimise its environmental impact through good design, and at some of the alternative, lower carbon cement and concrete products on the market.
Fuelled by the need to build quickly and to increasingly tight sustainability standards, the market for timber frame and mass timber construction is growing rapidly. This detailed guide covers many of the main established and emerging techniques, and looks at key issues to address if you’re considering a timber-based build.
