An indepth look at the forthcoming Directive on the Energy Performance of Buildings by Jeff Colley.

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.

At Tom Heneghan’s new development in Dromard, Belmullet, Co. Mayo, it’s a case of sixteen units down, eleven to go as Construct Ireland goes to press. Exceeding the thermal performance requirements of the Building Regulations by some 60%, these houses incorporate a range of innovative and affordable sustainable building technologies which together deliver high comfort, low energy living, as John Hearne reveals.

Richard Douthwaite investigates pensions and better ways to invest in our future

The unprecedented development seen in Ireland in the Celtic Tiger years was fueled by the availability of cheap, abundant fossil energy. As the boom ends, the state is attempting to boost the economy with investment in larger than ever infrastructural projects which will not benefit many of the tax payers who are funding them, and crucially don’t recognize the extent to which peak oil production will affect their viability, as Richard Douthwaite reveals.

A marked lack of adequate central government action to promote sustainable house building in Ireland has been recently counteracted by planning authorities such as Fingal County Council taking action into their own hands, and setting standards geared to protect their constituents in an oil and gas scarce future. However, as sustainable building consultant Will Woodrow discovered from surveying planning authorities around the country, local government willingness is not always met with a full grasp of the issues needed to make sustainable housing happen.

Turning a ruined farm house into a usable dwelling has been a dream for decades, but can an age-old structure really be brought-up to the cutting edge of energy efficiency? Architect Frank Cooney has found a way with a ruin in Cavan currently undergoing renovation. Jason Walsh visited the site to find out more.

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.

The winner of the sustainability award at the 2011 Irish Architecture awards, Roebuck Castle student residence at UCD’s Belfield campus is also the biggest certified passive house project built to date in Ireland and the UK. Tony Rigg of Kavanagh Tuite Architects explains how such a significant building achieved passive results.

The HARP database allows Building Energy Rating assessors to enter real performance data for heating appliances when calculating Building Energy Ratings rather than low default scores - but few renewable appliances are listed, and the industry appears confused and deterred by the application process. Lenny Antonelli investigates.
