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

Any building, no matter how cold and draughty, no matter how remote, can be improved to world-class energy performance, as an upgraded and extended Donegal cottage dating back to the 1800s proves.

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.

With oil prices remaining at ominously high levels in spite of sluggish economic growth figures and efforts by the International Energy Agency to release additional capacity, Ireland must act fast to cut oil usage. Why then, has the government withdrawn grants for renewables while continuing to subsidise oil and gas boilers?

Four years ago the construction industry was focused on building big and fast — but at the same time, a small team was carefully and ecologically retrofitting a terraced Dublin house on a tight budget according to passive house principles.

Although not a particularly sustainable building in many regards, there is much environmental merit in the Dominic Stevens designed Mimetic House, a 1300 Sq. ft structure built for e120,000  near Dromahair, Co. Leitrim. The house’s builder Conor McManus of GreenTek Construction, specialists in building highly ecological, low energy, airtight homes and extensions, describes the sustainable aspects of the house.

When it comes to redeveloping old buildings, green designers face two choices: replace existing structures with modern, energy efficient buildings or refurbish and avoid the embodied energy and waste of demolition and new construction. Lenny Antonelli visited a redeveloped convent in Booterstown, County Dublin that combines the best of both approaches.

Built in 2004, Tomás O’Leary's house in Wicklow was the first in the country to be certified by the Passive House Institute — but how would it fare when subjected to a BER assessment six years later?

‘Interest in sustainable construction, both from private sector individuals and businesses and from the public sector has grown rapidly in the last couple of years. Unfortunately the ability of the industry to respond to this interest is under developed’ – Tom Woolley.

Invest NI has itself invested in a new headquarters in central Belfast that it hopes will be seen as a model for sustainable development, as Richard Linger, Sustainability Director, White Young Green Ireland explains.
