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.

The notion that curbing CO2 emissions would damage economic growth has been used as an excuse from developed countries such as the USA not to switch from fossil fuels to renewable energy. However, as Richard Douthwaite reveals, the people of Austrian town Güssing are discovering firsthand that this couldn’t be further from the truth.

As Building Regulations tighten on carbon emissions, energy reduction and mandatory renewable energy targets, the task for designers becomes harder and harder. Bobby Gilbert of Bobby Gilbert and Associates explains how a new design tool is making sustainable design easier.

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

With over twenty years of design behind him, architect Martin Meyer has tackled plenty of big projects in his time, but his first home renovation challenge – to turn a dank 19th century red-brick house into a bright energy efficient home – was still eye-opening. Lenny Antonelli reports.

Air-tightness is a key factor in any low energy build, but is often overlooked in comparison to energy sources and insulation. Lenny Antonelli examines how air-tightness is achieved in buildings, from design stage down to the final sealing

Mixing excellent thermal performance with renewable heating, efforts to boost biodiversity and plans for micro-generation, a new timber frame house in rural Cork shows that both appealing design and low environmental impact can be achieved with one-off rural housing.

Ireland ’s reliance on fossil fuel sources for electricity generation places the whole country on unstable ground as these limited resources dwindle

Lime-hemp is developing as a bio composite construction material with serious ecological and energy advantages. Patrick Daly, lecturer in Environmental Design at DIT Bolton St. asks if this is the environmental material of the future and explores its mainstreaming potential.

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?
