Design Approaches

A typical Irish bungalow built in the early 1990s has been transformed with a green-tinted extension built in the spirit of modernism. Jason Walsh visited Enniskerry, County Wicklow to see how the old and the new were integrated

The environmental impact of the built environment extends far beyond energy consumption and carbon emissions throughout a building’s intended lifespan. Architect and sustainable design consultant Sinéad Cullen of DW EcoCo & BE Architecture explains why there’s a need to design buildings that can be deconstructed rather than destroyed once they reach their end of life, and looks at the obstacles to be overcome to make this happen.

Prestige commercial buildings can place a heavy toll on the environment, typically relying in Ireland on carbon intensive grid electricity to power air conditioning systems throughout the warmer parts of the year and inefficient electric lighting – often all year around. Completed in November 2004, software company SAP’s Galway offices offer a rare opportunity to find out how a natural ventilated and low energy lighting building is working in practice, as John Hearne reveals.

Stricter air-tightness standards might be helping to reduce energy use in new build, but is it leading to higher indoor concentrations of chemical and biological toxins? Lenny Antonelli investigates an emerging approach to building that is combining attention to environmental impact with consideration for the potential health effects of modern building materials and practices.

Award winning green architects Solearth have been at the vanguard of sustainable design in Ireland for over a decade. Solearth’s Brian O’Brien describes a highly ecological extension designed by the practice in west Dublin.

Atop a hill in New Ross, County Wexford, is a beacon for sustainability in large-scale developments, which draws extensively from across the palette of sustainable building options to achieve a building that is notable not just aesthetically, but also in health, energy and environmental impact terms. Jason Walsh visited the new Solar Croi spa, part of the Brandon House Hotel, Health Club and Spa, to find out more.

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.

The Transition Towns movement has recently come to the fore as a model for sustainable development, with communities around the world signing up to reduce carbon emissions and build resilience in a world where climate change and energy security are emerging as real threats. Leading eco designer Joseph Little of Joseph Little Architects describes how the recent refurbishment and extension of a Dublin house addresses many of the movement’s concerns.  

Kevin O’Flaherty’s development overlooking Galway Bay combines impressive energy saving techniques with the sorts of features that buyers of high-spec homes have grown to expect, as John Hearne discovers.

No matter how energy efficient a building method is, constructing a house from scratch will always cause some damage to the environment - but what if a building material could absorb more carbon than it causes to be released over its life cycle? Lenny Antonelli visits a hempcrete house in Co. Down that seeks to trial this innovative method of building
