The government is aiming to energy upgrade one million buildings by 2020, but huge investment will be needed to reach that goal as finance expert Jack O’Keeffe of Larchmont Consulting explains

At the start of July a key event in the Irish construction industry passed almost entirely unnoticed, with the requirement that the brand new Dwelling Energy Assessment Procedure (DEAP) calculation software be used for all planning applications for new homes with immediate effect. The new tool will be used to calculate Building Energy Ratings (BER) under the requirements of the Energy Performance of Buildings Directive (EPBD). Patrick Daly, lecturer in Environmental Design in the School of Architecture at DIT Bolton St. reveals his view on DEAP and its impact on the industry.

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

Four years ago the construction industry was focused on building big and fast — but at the same time, a small team was carefully and ecologically retrofitting a terraced Dublin house on a tight budget according to passive house principles.

External insulation examined: the reasons why placing insulation outside makes most sense, with six example projects

Air-tightness is a key factor in any low energy build, but is often overlooked in comparison to energy sources and insulation. Lenny Antonelli examines how air-tightness is achieved in buildings, from design stage down to the final sealing

Whilst great strides are being made in upgrading energy performance requirements under Part L of the Building Regulations, the issue of ventilation has remained largely ignored by legislators for years, leaving designers with antiquated standards to work to. At its worst, efforts to air-tighten and increase the insulation of homes is being undermined by the absurd practice of knocking holes in walls. John Hearne looks into what changes need to be made to modernise Part F.

Lenny Antonelli visited a recently refurbished complex of social housing flats in Galway city that has combined excellence in urban regeneration with energy efficiency and major strides towards sustainability

An increasing number of sustainable homes are being built in Ireland but many of them are in rural areas, and yet, Ireland is an increasingly urban society. Jason Walsh looks at one recent attempt to renovate a small terraced house in inner-city Dublin, bringing it up to modern environmental and energy efficiency standards.
