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.

With great attention to energy, materials and water, ABK Architects’ new civic precinct shows that smart green design can show no sign of compromise

Patrick Daly, co-founder of the RiSE (Research in Sustainable Environments) research unit in the DIT has undertaken an in depth study and critique of the current Irish Part L for energy efficiency in dwellings, comparing it in detail to the UK equivalent. The findings raise challenging questions about the Irish standards and methodology and highlight serious shortcomings in comparison to our UK neighbours, permitting substantially higher levels of CO2 emissions from new homes in Ireland than in the UK.

High energy prices and growing public eco awareness is leading to a situation where people are giving existing homes energy upgrades on an unprecedented scale. Two recently renovated houses in Dublin are at the extremes of how even the most difficult existing dwellings can be made greener, as Jason Walsh reveals.

In terms of 1972 money, oil prices averaged about six dollars a barrel between 1987 and 2000. Last October they reached $40. They are now around $50 a barrel which means that they are beginning to climb back into the territory which caused the global economy to crash in 1979/80.

Staggeringly airtight ecological home in Athenry set to meet the Passive House Institute standard

Part of the Mater Hospital redevelopment, the recently completed Mater Orchard building is a first class example of how to integrate sustainable building strategies into a substantial building whilst keeping extra cost to a minimum.

Richard Douthwaite explores the best options available to solve the intermittency problem of wind energy and help Ireland to harness its famously abundant natural resources

The notion that curbing CO2 emissions would damage economic growth has been used as an excuse from developed countries such as the USA not to switch from fossil fuels to renewable energy. However, as Richard Douthwaite reveals, the people of Austrian town Güssing are discovering firsthand that this couldn’t be further from the truth.

Four years ago the construction industry was focused on building big and fast — but at the same time, a small team was carefully and ecologically retrofitting a terraced Dublin house on a tight budget according to passive house principles.
