Passive houses have long been considered the ultimate in low energy buildings. So when it comes to BERs, why don’t they always get a straight A? Lenny Antonelli investigates.

The mainstreaming of sustainable building technologies is manifesting itself in a growing number of developers seeking to find the greener option. Jason Walsh describes a recent project where airtight timber frame construction meets high-tech solar thermal in a North Dublin House of Tomorrow funded scheme which is delivering low carbon results

Atop a hill in New Ross, County Wexford, is a beacon for sustainability in large-scale developments, which draws extensively from across the palette of sustainable building options to achieve a building that is notable not just aesthetically, but also in health, energy and environmental impact terms. Jason Walsh visited the new Solar Croi spa, part of the Brandon House Hotel, Health Club and Spa, to find out more.

A new development at Grange Lough, Rosslare, reveals that passive houses can be made Irish – both in terms of what they’re built with, and how they look.

With the age of cheap and abundant fossil fuel energy coming to an end, district heating, where a development is heated from a single, centralised heat source is becoming an increasingly attractive option due to the capital and running cost, efficiency and environmental benefits it can offer. Paraic Davis of Davis Associates mechanical and electrical engineers explains why district heating has become a viable and increasingly popular choice in Ireland.

In a comparatively short time, district heating and cooling have emerged as an ideal sustainable solution for mixed use, residential, commercial and industrial developments. Far from being a new technology, district heating systems have been commonplace across Europe since the 1960s. Noel Walshe BE of district heating specialists Noel Walshe ltd explains what is required to deliver the most effective solution.

Due to the ill-considered productivity of the house building industry towards the tail end of the economic boom, Ireland is now saddled with hundreds of thousands of vacant homes in various states of completion. Structural engineer Sadhbh Ní Hógáin, currently writing her thesis for a masters architectural degree in advanced environmental and energy studies at the Centre for Alternative Technology, looks at the options Ireland has to address the problem.

A new development in County Westmeath answers a nagging question about district heating: how to make it financially viable when it services energy efficient buildings. Lenny Antonelli visited a housing estate that combines low energy design with an innovative district heating system and ecological timber frame construction

RICHARD DOUTHWAITE proposes measures including energy upgrade of the housing stock  which could help to avoid economic meltdown, and JAY STUART outlines some energy saving measures which could be rolled out.

As fossil fuel prices rise, the need for energy efficiency in achieving both is increasingly leading Irish people to an approach which combines both ventilation and heating,
