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.

U-value alone is a blunt instrument for gauging the thermal performance of a building. Ground-breaking eco architects Joseph Little and Benat Arregi of Building Life Consultancy explain why our increasingly ambitious insulation efforts must involve a rigorous attention to thermal bridging if we’re serious about creating low energy, healthy buildings.

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.

Buildings that are designed or refurbished to use little energy all too often fail to deliver the expected performance, if the building occupants aren’t able to use the building as intended. John Hearne reveals the crucial role that user-friendly heating controls play in ensuring that a theoretically low energy building delivers the expected results.

The mainstreaming of sustainable building technologies is manifesting itself in a growing number of developers seeking to find the greener option. Jason Walsh describes a recent project where airtight timber frame construction meets high-tech solar thermal in a North Dublin House of Tomorrow funded scheme which is delivering low carbon results

Sustainable Energy Ireland was initially criticised by some quarters for the lack of vetting of renewable energy installers registered under the Greener Homes Scheme. However, the recent introduction of mandatory training for those on the register has also proven controversial, writes Lenny Antonelli.

Ernst Posthuma of Solarcon sheds light on a demonstration project in west Cork that combines passive and active solar gains to remarkable effect.

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.
