The natural step

A framework for strategic sustainability is essential if we’re serious about greening the Irish built environment.
According to green architect Pat Barry, we should look no further than The Natural Step.
Welcome to the archive of Construct Ireland, the award-winning Irish green building magazine which spawned Passive House Plus.
The feature articles in these archives span from 2003 to 2011, including case studies on hundreds of Irish sustainable buildings and dozens of investigative pieces on everything from green design and building methods, to the economic arguments for low energy construction.
While these articles appeared in an Irish publication, the vast majority of the content is relevant to our new audience in the UK and further afield. That said, readers from some regions should take care when reading some of the design advice - lots of south facing glazing in New Zealand may not be the wisest choice, for instance.
Dip in, and enjoy!

Completed in December 2009, Graham Group’s new headquarters reveal the construction and asset management company’s commitment to green building. The project’s sustainability adviser, Chris Croly of BDP describes an innovative design that pushes the boundaries of natural ventilation and takes a thoughtful approach to materials and buildings services to ensure a minimal environmental impact.

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.

In April this year the first NSAI Agrément certificate was issued for the application of external insulation to existing dwellings. Joseph Little of leading green architects Joseph Little Architects used analysis from his practice’s Building Life Consultancy service to assess the certificate, and encountered issues which raised questions over whether it should have been issued in its current form.
If achieving eco buildings is challenging for new build, it is doubly so for renovation projects.
Philip & Delphine Geoghegan of iCon Architecture & Uban Design describe a low impact renovation that balances these apparent tensions with great success.

With the age of cheap and abundant fossil fuel energy coming to an end, district heating, where a development is heated from a single, centralised heat source is becoming an increasingly attractive option due to the capital and running cost, efficiency and environmental benefits it can offer. Paraic Davis of Davis Associates mechanical and electrical engineers explains why district heating has become a viable and increasingly popular choice in Ireland.
