Ron and Collette Wardle started suffering ill health almost immediately after a sloppy energy upgrade. But reading a copy of Construct Ireland started a chain of events that led to the couple getting a brand new ventilation system — and seeing a marked improvement in their health.

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

Marie Stamp, Senior Trade Commissioner at the Canadian Embassy, Dublin, discusses the merits of Super E home build.

As energy prices continue to rise, the Irish construction industry is moving into uncharted territory, where all elements that affect energy performance—from orientation, to building design, to specification, to standard of workmanship—are increasingly recognised as key concerns.

It has long been anticipated that the cost of sustainable building will come down as it enters the mass market, benefiting from economies of scale and greater industry confidence in low impact techniques and technologies as they become more familiar. Jay Stuart, managing director of integrated sustainable design consultants Delap and Waller EcoCo reveals a Kildare housing project which is likely to rapidly accelerate this process, and convince even the most conservative elements of the industry that low energy, low carbon building can be achieved at little or no additional cost

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.

Ireland has been waiting for a green procurement plan in the public sector for two years. Jason Walsh looks at what the plan should include and why it is needed, now more than ever, and with sustainable building at its core.

Ill-considered attempts to upgrade a building’s thermal performance can not only fail to save energy, but can also create serious problems for occupant health and building structure alike. Leading green designer Joseph Little of Joseph Little Architects investigates the particular problems associated with dry-lining single-leaf concrete block walls

Much of the housing built around Dublin over the last forty years has been built of single-leaf nine-inch hollow block construction – which are both notoriously energy inefficient and extremely difficult to insulate effectively without causing damp problems. Lenny Antonelli visited a hollow block house which has been ecologically renovated to protect occupant health whilst shooting to the top of the energy rating scale.
