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.

Achieving building regulations compliance and a good energy rating is one thing. Delivering a genuinely low energy building is quite another. A new scheme by one of Ireland’s most decorated developers may help show the market a way forward.

With oil prices nearing record highs, forward thinking developers who’ve taken the initiative to incorporate green aspects into their projects are showing a buoyancy that starkly contradicts the downturn, as John Hearne reveals.

The government is aiming to energy upgrade one million buildings by 2020, but huge investment will be needed to reach that goal as finance expert Jack O’Keeffe of Larchmont Consulting explains

The cement industry is well known as being amongst the worst culprits for emitting CO2, a seemingly unavoidable side effect of its production. However, as Peter Seymour, Business Development Manager with Ecocem Ireland Ltd explains, there is a strong, eco-friendly competitive alternative to Portland cement that is being specified in a variety of high profile construction projects in Ireland.

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.

Construct Ireland spoke to Adi Roche to find out about the progress so far, and the need for continuing support.

Fingal County Council have clearly shown a laudable commitment to innovation by introducing a mandatory planning requirement for seven areas that all new developments reduce energy use and C02 emissions relating to space & water heating to 60% below Building Regulations requirements, with 30% of space & water heating coming from renewable energy sources
