Nottingham passive house enters Solar Decathlon

Whilst great strides are being made in upgrading energy performance requirements under Part L of the Building Regulations, the issue of ventilation has remained largely ignored by legislators for years, leaving designers with antiquated standards to work to. At its worst, efforts to air-tighten and increase the insulation of homes is being undermined by the absurd practice of knocking holes in walls. John Hearne looks into what changes need to be made to modernise Part F.

Brian Homan, Joint Managing Director of leading consulting engineers Homan O’Brien Associates describes a nursing home currently being built that is adopting a sustainable building approach to deliver healthy, comfortable accommodation at low running costs.

High levels of external insulation, abundant natural light and a minimalist approach to ventilation are ensuring that Malahide Lawn Tennis and Croquet Club is as green as its courts

 
A framework for strategic sustainability is essential if we’re serious about greening the Irish built environment.
According to green architect Pat Barry, we should look no further than The Natural Step.

There’s rather more to designing a sustainable building than specifying low-embodied energy materials and making sure it will require little energy and maintenance in use. Low water demand and the ability to get the nutrients discharged in the sewage back to the land are important too.

Hotels typically take a heavy toll on the environment, with large amounts of energy used for heating, hot water, lighting, air conditioning and laundry, and huge amounts of waste being landfilled each year. John Hearne visited the Westport Woods Hotel and discovered a highly successful approach to reducing environmental impact that is also yielding substantial dividends in terms of cost savings and positive publicity

When the two worlds of heritage and development collide opinions frequently become polarised and fraught with difficulty. There are few more vexed issues, as Tim Carey, Heritage Officer with Dun Laoghaire Rathdown County Council reveals

A log bungalow in rural Meath has been extended and given a total energy upgrade – and wood is at the heart of the renovation, with a timber frame extension and external insulation system along with a fresh log finish.
