In this adapted extract from his new book Natural Building: A Guide to Materials and Techniques, seminal eco architect Professor Tom Woolley outlines some of the reasons why natural building is necessary.

Solearth partner & Éasca board member Mike Haslam profiles five inspiring English and US projects that share a similarly considered green design approach.

Designing a low energy building when you've got unlimited space is one thing – but what if you need to make your walls thin to maximise space on a small site in an architectural conservation area? Lenny Antonelli visited a new St Vincent De Paul sheltered housing project that fit a lot of sustainable features on to a small plot in Dublin's north inner city.

An energy conscious renovation and extension in south Dublin breathes new life into a typical semi detached home — the house is now wrapped with external insulation and boasts breathable and ecological materials too.

As policy makers start to set mandatory low energy and renewable energy requirements as conditions of planning, the ability of the construction industry to find sound low-cost ways of achieving the new standards is becoming a key factor. John Corless speaks to leading sustainable building consultant Jay Stuart of Delap & Waller EcoCo and Paul Gilmartin of Ecobead to discover an approach with enormous potential for en-masse usage.

Every eurozone government has debt problems and is cutting its spending, Richard Douthwaite says. Defaults and a prolonged depression are inevitable unless countries inject money into their economies in an unconventional way. A prosperous low-carbon economy would be the result

If you’re applying for planning permission to build in Cappagh, North Ballymun or Northwest Balbriggan, 30% of your heating must come from renewable energy, and your heating must be less than 50Kwh/m2 per annum—roughly twice the standard of most new homes.

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.
