Richard Douthwaite proposes a new bank-free, debt-free way of financing property purchase and development to get the market working again and clear up the mess left by the bubble.

Richard Douthwaite looks at the viability of heat pumps, and the factors that could determine their future role in a changing energy landscape.

A recent study instigated by the American Environmental Protection Agency has identified indoor air quality as one of the top five urgent environmental risks to public health.

It could be a reflex response to the shockingly poor construction standards that came to define Ireland’s boom years, but the world’s leading low energy building standard is starting to thrive in Ireland. As the several case studies following this article reveal, a groundswell of Irish clients, designers, contractors and manufacturers are starting to recognise the opportunities available in becoming early adopters of a standard destined for exponential global growth.

Ireland has been waiting for a green procurement plan in the public sector for two years. Jason Walsh looks at what the plan should include and why it is needed, now more than ever, and with sustainable building at its core.

Energy efficiency is about more than just U-values – the building envelope must be airtight and virtually cold bridge free. Construct Ireland visited a single-leaf concrete house nearing completion in Moate which combines an excellent envelope with wind, solar and a range of green measures, with the aim of reducing energy and carbon figures to zero in the home’s BER score.

With the goal of achieving zero carbon standards for new homes by as soon as 2013, environment minister John Gormley has committed to introducing 60 per cent energy and carbon reductions under changes to part L of the building regulations next year. John Hearne spoke to leading industry figures to find out how the revised regulation could raise standards for both new and existing homes.

Prestige commercial buildings can place a heavy toll on the environment, typically relying in Ireland on carbon intensive grid electricity to power air conditioning systems throughout the warmer parts of the year and inefficient electric lighting – often all year around. Completed in November 2004, software company SAP’s Galway offices offer a rare opportunity to find out how a natural ventilated and low energy lighting building is working in practice, as John Hearne reveals.
