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

Whilst great strides are being made in upgrading energy performance requirements under Part L of the Building Regulations, the issue of ventilation has remained largely ignored by legislators for years, leaving designers with antiquated standards to work to. At its worst, efforts to air-tighten and increase the insulation of homes is being undermined by the absurd practice of knocking holes in walls. John Hearne looks into what changes need to be made to modernise Part F.

Responding to the Department of Communications, Marine & Natural Resources’ Green Paper “Towards a Sustainable Energy Future for Ireland”, Mark Coyne, Technical Director of Dalkia Ireland, outlines the challenges and responses to the three main pillars of the Green Paper – sustainability, competitiveness and security of supply.

A new timber frame house in the Wicklow hills is arguably the most airtight building ever built in Ireland, boasting wood fibre external insulation and an obsessive attention to sealing

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.

The rapid emergence of sustainable building in Ireland has been heavily influenced by the techniques of early-adopters extending from Scandinavia, to Canada, to Germany and Austria. John Hearne visited a recently completed timber home in Galway which uses Austrian know-how to couple air-tightness, high levels of insulation and healthy materials with a sustainable approach to heating and ventilation

Nowhere demonstrates the need for a high-performance building envelope quite like a coastal site. John Hearne visited a cutting edge timber frame house overlooking Sligo Bay that was designed to achieve a highly insulated, air-tight and low embodied energy envelope whilst making the most of the spectacular vista.
