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

A recent study undertaken by Dublin City Council could serve to shatter many commonly held misconceptions about how existing buildings can perform when compared to new build, even simply just in terms of running costs.

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.

“The thing to bear in mind is that even though it got knocked down, every single window sill went into another house, all the flooring and slates went into another house”, says Stephen Porter of Stonebrokers on the recent demolition of Lough na Vale in Sandymount.

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

Do termites apply building science better than humans? Award winning architect Sean Harrington takes a characteristically left-of-brain approach to our international feature, leading to some humbling lessons.

If the issue of sustainability is to truly be on the agenda in terms of construction and development, it is nowhere more evident than in how we approach insulation. Recognition of the economic and environmental benefits of properly insulating our buildings is being called for by experts on environmentally conscious construction, such as RTE TV presenter Duncan Stewart

When Construct Ireland asked Vivienne Brophy of the UCD Energy Research Group to select projects for this feature she suggested that the second year UCD Architecture students make the selection, using UCD’s sustainable building rating system tool to verify their choice

As long term readers of Construct Ireland will recall, the mainstreaming in recent years of sustainable design and construction has been exemplified in many innovative local authority offices. John Hearne visited Aras Contae an Chláir, and discovered a building which attempts to holistically minimise environmental impact, with attention paid to more than just energy performance and carbon emissions.

Part of the Mater Hospital redevelopment, the recently completed Mater Orchard building is a first class example of how to integrate sustainable building strategies into a substantial building whilst keeping extra cost to a minimum.
