In 2005 Construct Ireland profiled the timber frame extension to Hannah and Martin Naughton’s Meath cottage. Five years later we’re returning to profile the upgrade of the original bungalow — a renovation that demonstrates how to detail dry lining without running the risk of mould growth

A striking new house in County Cork proves that meeting the passive house standard needn’t mean sacrificing good design

In April this year the first NSAI Agrément certificate was issued for the application of external insulation to existing dwellings. Joseph Little of leading green architects Joseph Little Architects used analysis from his practice’s Building Life Consultancy service to assess the certificate, and encountered issues which raised questions over whether it should have been issued in its current form.

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.

Air-tightness is a key factor in any low energy build, but is often overlooked in comparison to energy sources and insulation. Lenny Antonelli examines how air-tightness is achieved in buildings, from design stage down to the final sealing

Energy Minister Eamon Ryan recently announced a e9 million fund to be administered by SEI for sustainable housing including, crucially, micro-generation of renewable electricity. Jason Walsh talked to SEI and industry figures to examine the scheme’s future.

Unless greenhouse gas emissions from land are tackled, any efforts to reduce emissions from buildings may fall short in attempting to stave off the worst consequences of climate change. Richard Douthwaite explains how, with a little ingenuity, techniques can be applied to dramatically reduce land emissions whilst simultaneously providing new raw material streams and energy source

With the publication earlier this year of three reports on drinking water quality, urban waste water discharges, and implementation of the phosphorous regulations, the EPA’s Office of Environmental Enforcement(OEE) has presented an overview of water management by local authorities in Ireland. Presented as a package of reports, they paint a picture of how local authorities are doing in relation to the management of water resources in the country. Construct Ireland’s Jeff Colley speaks to Doctor Matt Crowe, Programme Manager of the OEE on the state of national water quality.

Designing a low energy building when you've got unlimited space is one thing – but what if you need to make your walls thin to maximise space on a small site in an architectural conservation area? Lenny Antonelli visited a new St Vincent De Paul sheltered housing project that fit a lot of sustainable features on to a small plot in Dublin's north inner city.

Bank of America Tower, to be located at One Bryant Park in midtown Manhattan is a US$1 billion project that has been designed to be one of the most highly efficient and ecologically friendly tall buildings in the world. The building, currently under construction, is expected to be complete in 2008.

Jason Walsh got in touch with Cook + Fox Architects in New York, designers of the Bank of America Tower to see how the practice plans to square the circle of designing an environmentally sound high-rise building.
