Sustainable Dundalk housing project designed to prolong the independence of older residents

Solearth partner & Éasca board member Mike Haslam profiles five inspiring English and US projects that share a similarly considered green design approach.

The Dwelling Energy Assessment Procedure (DEAP) is now the national methodology for creation of Building Energy Rating (BER) Certificates for new dwellings in Ireland, and is an important desk top tool for predicting the performance of projects at outline design stage.

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.

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.

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.

With the threats posed by anthropogenic climate change now accepted as a key international issue, efforts to curb carbon dioxide emissions are becoming manifest around the world in spite of – and even as a response to – the global recession. But any such efforts may be in vain if the focus on carbon dioxide distracts from the need to curtail methane emissions, as Richard Douthwaite explains

Any building, no matter how cold and draughty, no matter how remote, can be improved to world-class energy performance, as an upgraded and extended Donegal cottage dating back to the 1800s proves.

A new timber frame house in the Wicklow hills is arguably the most airtight building ever built in Ireland, boasting wood fibre external insulation and an obsessive attention to sealing

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.
