A detailed analysis of the embodied carbon of six common build types has indicated that dwellings built with business-as-usual build specs of cavity wall construction and strip foundations may be able to meet the revised embodied carbon targets for dwellings in RIBA’s 2030 Climate Challenge.

Hastoe Housing, a trailblazer in the development of affordable passive housing, have completed their second scheme in the Essex village of Wimbish — 11 houses whose simple and traditional building methods and materials mask cutting-edge energy efficiency.

Built with a timber frame insulated with straw-bale, and featuring an extensive suite of ecological and recycled materials, this stunning North Yorkshire home also produces more energy than it consumes, making it the first straw-bale building in the world to reach the brand new ‘passive house plus’ standard.

This large family home in south Dublin proves that big homes don’t need to be cold and draughty, comfortably beating Ireland’s planned nearly zero energy building standard for 2021 — even though it was finished in 2015.
