In the second installment of a new feature on international green buildings, Lenny Antonelli takes a look at four innovative, sustainable and striking buildings from around the world.

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.

A sustainable energy project in north Tipperary has the potential to create a pioneering green community – buildings are getting energy makeovers, grants are available for renewables and the ecovillage at Cloughjordan is under construction. But getting householders in the area to go green is still proving a hard sell, as Lenny Antonelli reports

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

Construct Ireland spoke to Adi Roche to find out about the progress so far, and the need for continuing support.

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 advent of central heating improved the comfort of life for countless Irish people over the past century, but as energy efficient building grows, some pioneering homeowners think they can live without it. What’s life like for them?

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.

In light of Ireland’s poor performance in the recent European Environment Agency Report on drinking water quality, the issue of Ireland’s wastewater treatment from one off houses is poised to stay in the spotlight. Construct Ireland’s Pat Kennedy, environmental engineer, investigates.
