Thermal mass can significantly influence a building’s space heating requirement – in some cases the effect is to increase it, and in others to reduce it. Leading energy consultant Ciaran King of Emerald Energy explains how this occurs, and by describing an assessment of the topic, provides some rules of thumb regarding when thermal mass may be beneficial, and when it may be detrimental.

SEAI recently proposed a series of changes to Deap — the software tool used to calculate BERs — including a reduction in its primary energy factor. But while this will benefit electrically-powered heating devices, some in the industry still feel systems such as heat pumps are disadvantaged by Deap and the BER system

Designed and patented by Irish firm NuTech Renewables, solar enhanced ventilation aims to bring big energy and cost savings to the retrofit market by combining solar and ventilation technologies. NuTech’s Bill Quigley explains how it works.

Upgrading and extending a semi-detached house on a tight site in Limerick required ingenuity from architect Patti O’Neill.

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.

Award winning green architects Solearth have been at the vanguard of sustainable design in Ireland for over a decade. Solearth’s Brian O’Brien describes a highly ecological extension designed by the practice in west Dublin.

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.

A cursory browse through Dublin Civic Trusts website and one is all too quickly reminded of the constant threat to our Architectural heritage

Sustainable architect Simon McGuinness describes a project in Dublin which is set to surpass the onerous standard using structural insulated panels.

In spite of the obvious emergence of technologies and design approaches to reduce the impact of new build, environmental standards remained poor throughout the duration of the housing boom. Now, a unique combination of political will, smart incentives, and a new market of informed and empowered buyers may be about to change that, writes Lenny Antonelli
