Um dos maiores desafios à implementação de programas de eficiência energética à escala das cidades, sobretudo tendo em conta a complexidade e diversidade construtivas das grandes cidades e cidades com centenas de anos, é modelar as próprias estratégias de eficiência. Que grau de intrusão —em matéria de alterações e requalificação— pode ser considerado aceitável? Que tipologias de intervenção? Que custos? Que parcerias e plataformas colaborativas poderão ser construídas para proceder a operações em larga escala? Como justificar e financiar os investimentos necessários sem provar previamente a qualidade das soluções? Recriar em ambiente de laboratório, casas e bairros, pode ser o caminho certo. — CS
Leaky 1930s test house gets 2016-style makeover
Posted by Greenbang on August 6th, 2009Why would the University of Nottingham build a house meeting 1930s specifications in 2008? So it can use it as a guinea pig for a zero-carbon renovation experiment, the results of which will be relevant to millions of householders across the UK.
The house is about to undergo the first of three planned energy-efficiency upgrades ultimately aimed at helping it meet the Government’s 2016 zero-CO2 targets for all new housing. Over the next two weeks, the university will improve the house with cavity wall insulation, loft insulation, draft-proofing, double-glazing and other upgrades.
The university actually had to seek special planning permission when it built the house to 1930s standards. The building features open fires, single-glazed windows, inefficient water heating and no insulation. The 1930s semi is an icon of its age; three million were built and they remain a major part of the UK’s current housing stock.
The three-year research project to transform the structure to a zero-carbon one is being led by experts from the School of the Built Environment together with the energy firm E.ON.

The E.ON 2016 House is part of the Creative Energy Homes project, which has seen a total of six new homes built on University Park. Green Close showcases innovative state-of-the-art energy efficient housing of the future. The project is testing of different aspects of modern methods of construction, including layout and form, cladding materials, roof structures, foundations, glazing materials, thermal performance, building services systems, sustainable and renewable energy technologies, lighting systems, acoustics and water supply. The project aims to stimulate sustainable design ideas and promote new ways of providing affordable, environmentally sustainable housing that are innovative in their design. — in Greenbang.

1930s home goes green
Dr Mark Gillott, who is leading the research, said: “The house provides us with a unique test facility to measure the exact cost benefit, energy efficiency and carbon reduction figures achieved through the various upgrade measures we are implementing over the next two weeks — valuable information when deciding on which of the many energy efficiency measures are the most cost effective.” — in The University of Nottingham, Communications.
