The Passive House standard, an internationally renowned approach to building that negates the need for conventional heating, has attracted considerable interest in Ireland recently as energy prices continue to rise. Vivienne Brophy, Dr Irena Kondratenko, Patxi Hernandez and Kevin Burke of UCD’s Energy Research Group look at the effect this approach could have on cutting Ireland’s energy consumption and CO2 emissions.

Thermal mass can significantly influence a building’s space heating requirement – in some cases the effect is to increase it, and in others to reduce it. Leading energy consultant Ciaran King of Emerald Energy explains how this occurs, and by describing an assessment of the topic, provides some rules of thumb regarding when thermal mass may be beneficial, and when it may be detrimental.

The Orchard, a new building on the campus of Stranmillis College, a teacher training college in Belfast, has become the first winner of a sustainable planning award organised by the Royal Town Planning Institute alongside a host of other awards. Jason Walsh visited the new building to find out about its green credentials.

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.

Thanks to the ESCo model, one school in Donegal has gone green, seen its heating bills reduced by 15% yet has not had to outlay one cent in capital expenditure. John Hearne investigates an emerging trend that is bringing low carbon energy into another realm.

Recently sold by private tender for over e1.3 million, the ECO House in Shankill, Co. Dublin exceeded auctioneers expectations, an indicative example of the shift from public curiosity to eagerness to invest in contemporary sustainable building.

Construct Ireland’s John Hearne discovers the growing shift towards making sites independent in terms of both water supply and wastewater treatment.

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.

Richard Douthwaite explains how inadequate conventional energy generation is and reveals the potential that combined heat and power & energy service companies can offer.

Planning ahead for Ireland’s electricity supply is by no means a simple matter, given the range of unprecedented issues that are coming to the fore.  Massive cuts in emissions must be achieved, whilst decisive action is required to ensure adequate supply of electricity at a time when usage is spiraling. Richard Douthwaite explains the balance that Ireland must achieve between efficient local generation and usage and ensuring optimal interconnection to global renewable electricity supply
