The government is aiming to energy upgrade one million buildings by 2020, but huge investment will be needed to reach that goal as finance expert Jack O’Keeffe of Larchmont Consulting explains

Some buildings, by their nature, tend to have larger energy requirements. Occupied around the clock, with occupants who feel the cold, nursing homes are a case in point. John Hearne visited a north Dublin building where a range of different sustainable technologies operate in tandem to deliver the residents’ heating and hot water requirements

When designing and building high density apartment and housing developments, the attention, so often lacking, to acoustic performance, can have a critical impact on the quality of life of the buildings’ inhabitants, as leading acoustic consultant Jim Dunne, Managing Director of Integrated Acoustic Solutions explains

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.

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.

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.

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

A recent study instigated by the American Environmental Protection Agency has identified indoor air quality as one of the top five urgent environmental risks to public health.
