Construct Ireland Journalist Frank Coles investigates the impact posed by the Energy Performance of Buildings Directive

In the first installment of a new feature on international green buildings, Lenny Antonelli takes a look at five innovative, sustainable and striking buildings from around the world.

Based on past form, the Department of the Environment officials could be forgiven for bracing themselves for a construction industry backlash in response to the proposed changes for Part L of the building regulations which aim to both improve energy efficiency and reduce carbon emissions by 40%, whilst also introducing mandatory renewable energy and air tightness requirements. Jeff Colley outlines why, for reasons of self interest alone it’s very much in the industry’s interests to embrace the new regulations rather than attempt to resist change.

A recent study undertaken by Dublin City Council could serve to shatter many commonly held misconceptions about how existing buildings can perform when compared to new build, even simply just in terms of running costs.

The rendering industry in Ireland is in a process of change and thus has been the centre of much heated debate between renderers, the meat industry, Irish livestock farmers and the Department of Agriculture and Food.

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.

Imaginosity, the new children's museum building in Sandyford's Beacon South Quarter development, is getting the Austrian eco-house treatment, combining low energy, modular construction with a plethora of low carbon energy technologies. Jason Walsh visited the site to take a look.

Ernst Posthuma of Solarcon sheds light on a demonstration project in west Cork that combines passive and active solar gains to remarkable effect.

Chris Croly from BDP outlines the low energy and renewable energy strategies used in University College Cork’s new Environmental Research Institute, a test bed for the design and performance of sustainable buildings, which is ideally suited to housing the 200+ environmental projects carried out by its researchers.

In recent years it’s become increasingly accepted that the age of cheap and abundant oil and gas supplies is coming to an end, and that future energy needs will have to be met from cleaner, more widely available fuel sources. According to Richard Douthwaite, the prospects of exponentially rising costs and failure to ramp up carbon capture and storage will mitigate against coal’s ability to take up the slack
