As Building Regulations tighten on carbon emissions, energy reduction and mandatory renewable energy targets, the task for designers becomes harder and harder. Bobby Gilbert of Bobby Gilbert and Associates explains how a new design tool is making sustainable design easier.

The emergence of climate change as a serious concern has helped create a burgeoning market for a vast range of eco technologies. All too often, however, the basic principles of sustainable design are ignored or misunderstood. Chris Croly of mechanical and electrical engineers Building Design Partnership describes the detail of a building which reveals a no-nonsense attention to sustainability.

Long-caricatured as resource destroying monsters clad in steel and glass, the skyscraper is rarely viewed as an environmentally sound form of architecture. Construct Ireland’s Jason Walsh looks at efforts underway to change that perception.

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.

Completed in December 2009, Graham Group’s new headquarters reveal the construction and asset management company’s commitment to green building. The project’s sustainability adviser, Chris Croly of BDP describes an innovative design that pushes the boundaries of natural ventilation and takes a thoughtful approach to materials and buildings services to ensure a minimal environmental impact.

An energy conscious renovation and extension in south Dublin breathes new life into a typical semi detached home — the house is now wrapped with external insulation and boasts breathable and ecological materials too.

Much of the debate on reducing international carbon emissions has focused on the extra cost of making the necessary cuts to slow the onset of climate change. According to Richard Douthwaite, the Irish Government is considering introducing Cap and Share, a system which would actually earn ordinary Irish people money for reducing emissions.

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.

SEAI recently proposed a series of changes to Deap — the software tool used to calculate BERs — including a reduction in its primary energy factor. But while this will benefit electrically-powered heating devices, some in the industry still feel systems such as heat pumps are disadvantaged by Deap and the BER system

Mixing excellent thermal performance with renewable heating, efforts to boost biodiversity and plans for micro-generation, a new timber frame house in rural Cork shows that both appealing design and low environmental impact can be achieved with one-off rural housing.
