Building energy demand could be reduced by 50% compared to a basic rehabilitation action with SATE systems, that currently can already reach energy demand values in buildings of around 30 kWh / m2 / year.
Toshiba Heating and Air Conditioning and ASA (Sustainability and Architecture Association) have granted the ReHabilitando 2016 award to an idea that stands out for its research and innovation in the use of water as an energy source, the use of artisanal construction techniques and proposal for participation of local artisans in the manufacture and development of architectural solutions, climatization and energy proposals.
A Passivhaus is a building that saves energy. This concept, born in Germany almost 30 years ago, consists in combining a high interior comfort with low energy consumption and very affordable price. So far in Spain it was applied to single-family homes, but this is no longer the case, because in Pamplona the first block of flats under these criteria can be now found.
Energy efficiency will be key in the homes of the future. Therefore, new measures are being investigated to improve the quality of their construction. It is the case of CIRCE (Center for Research on Energy Resources and Consumption) of the University of Zaragoza, which together with Zaragoza Vivienda and Acciona Infrastructures, is participating in a R + D project on energy rehabilitation.
Prince Charles has always shown great interest in the conservation of nature, so it is not surprising that the property he owns in Adelaide, the capital and most populous city of South Australia state, is to become the most sustainable and ecological in the country. It is a complex of low energy consumption residential houses.
Buildings renovation and sustainable construction is becoming an economic engine in Andalusia. The Housing and Rehabilitation Agency of Andalusia (AVRA) has launched more than one hundred initiatives in public housing, to improve their energy conditions and for families to save in consumption while improving their comfort level.
The publication in September 2013 of the new Building Code in its section on Energy Saving ( CTE DB- HE), in force since March 14 , has lead ANDIMAT ( National Association of Manufacturers of insulating materials ) to publish a series of case studies that aim to help the technical people responsible for justifying compliance with the new CTE HE1 .
The Rockwool company summarizes the main changes in the new Basic Document of Energy Saving in Buildings DB -HE of the Technical Building Code (CTE) in their guide "What changed from March 12 ?". In the Document, the requirements in new building are increased to reduce energy consumption and demand and new specifications for already built ones are also included.
The change that occurs in Velux’s experiment to renovate old houses is impressive at first sight. LichtAktiv Haus is a pilot project to demonstrate the feasibility of new solutions in the renovation of old houses combining in the best possible way energy efficient architecture with an optimal quality of life.
