When it comes to redeveloping old buildings, green designers face two choices: replace existing structures with modern, energy efficient buildings or refurbish and avoid the embodied energy and waste of demolition and new construction. Lenny Antonelli visited a redeveloped convent in Booterstown, County Dublin that combines the best of both approaches.

Creating the right comfort in buildings for elderly people involves ensuring a warm internal environment, which typically results in high energy consumption. John Hearne visited the new Castle Gardens Retirement Village as it approached completion and found a project that combines complimentary low energy technologies, materials and design to deliver high levels of comfort whilst also keeping running costs, energy consumption and carbon emissions low

Bank of America Tower, to be located at One Bryant Park in midtown Manhattan is a US$1 billion project that has been designed to be one of the most highly efficient and ecologically friendly tall buildings in the world. The building, currently under construction, is expected to be complete in 2008.

Jason Walsh got in touch with Cook + Fox Architects in New York, designers of the Bank of America Tower to see how the practice plans to square the circle of designing an environmentally sound high-rise building.

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?

No matter how energy efficient a building method is, constructing a house from scratch will always cause some damage to the environment - but what if a building material could absorb more carbon than it causes to be released over its life cycle? Lenny Antonelli visits a hempcrete house in Co. Down that seeks to trial this innovative method of building

Duncan Stewart demands an energy revolution

It has long been anticipated that the cost of sustainable building will come down as it enters the mass market, benefiting from economies of scale and greater industry confidence in low impact techniques and technologies as they become more familiar. Jay Stuart, managing director of integrated sustainable design consultants Delap and Waller EcoCo reveals a Kildare housing project which is likely to rapidly accelerate this process, and convince even the most conservative elements of the industry that low energy, low carbon building can be achieved at little or no additional cost
