Stricter air-tightness standards might be helping to reduce energy use in new build, but is it leading to higher indoor concentrations of chemical and biological toxins? Lenny Antonelli investigates an emerging approach to building that is combining attention to environmental impact with consideration for the potential health effects of modern building materials and practices.

Hugh Dorrian, member of the Main Committee of the recently launched Building Limes Forum Ireland reveals lime is regaining ground as a key material not only in conservation projects, but in new build.

John Hearne explains how truly low energy buildings can succeed or fail depending on how they engage with their occupants.

As the January 2006 deadline for implementation of the EU Directive on the Energy Performance of Buildings draws ever nearer, the Irish Government has spelt out its plans to delay the across the board introduction of building energy ratings until 2009. But how does this compare to other EU Member States?

Government incentives are crucial to sparking a massive energy upgrade of our housing stock, but practical examples are just as important. Keen to push his home's energy performance to the limits, one Dublin homeowner overhauled his entire building fabric and installed renewable heating systems and heat recovery ventilation. Lenny Antonelli visited the house.

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

Ill-considered attempts to upgrade a building’s thermal performance can not only fail to save energy, but can also create serious problems for occupant health and building structure alike. Leading green designer Joseph Little of Joseph Little Architects investigates the particular problems associated with dry-lining single-leaf concrete block walls

Jason Walsh visited the recently refurbished offices of Wicklow County Council to see an approach that achieves energy conservation, carbon reduction and dramatically increased occupant comfort by lowering electricity and heat demand and avoiding unwanted overheating

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

For a building to truly be considered a passive house a vast range of criteria need to be met, as Niels Bjergstrom, founder of Zero-Carbon Solutions Ltd reveals.
