In trickier housing markets, the instincts of house builders have often tended towards building to the worst legal standards required – or worse. One award-winning new project in Belfast’s suburbs is showing that it doesn’t have to be this way – and that developers can thrive by pitching homes designed to ensure comfort and low bills at increasingly energy-conscious consumers.

The historic Roman city of York is embarking on an ambitious programme to redefine council housing for the 21st century, building 450 mixed-tenure passive houses across eight sites in the city, and unashamedly prioritising walking and cycling, and shared outdoor green spaces, over cars. It may seem too good to be true, but a cityscape whose architecture still so manifestly displays its extraordinary history is now pointing to the future of urban design.

A rundown 1970s scheme of one-bedroom, single storey social housing units in Ballyshannon, Co Donegal, has been transformed into a pioneering development of cosy, A-rated, NZEB-busting homes. The pioneering project – the first completed under Ireland’s deep retrofit pilot scheme – also breathed new life into an unloved green area and is expected to help fuel a regeneration project in the town.

A luxury new development in an exclusive Dublin location will achieve nearly zero energy building (NZEB) standards with help from Daikin Altherma air-to-water heat pumps and a highly energy efficient building fabric.

With a number of trailblazing housing associations and councils building social and affordable housing schemes repeatedly to passive standards, the notion that the world’s leading low energy building standard is the preserve of the well-off doesn’t stand up to scrutiny, as Hastoe’s latest Essex passive house scheme demonstrates. 

Bristol City Council have appointed Gale & Snowden Architects as lead consultants on a scheme of 23 dwellings aiming for passive house plus certification.
