Case studies

These apartment houses in Roncq are Passive House certified and their thermal envelope and mechanical systems have efficient energy consumption results. Moreover, the buildings recover energy from grey water.

This social housing block in Paris has been renovated by architect Jean-Christophe Quinton who has worked on the facade by making it more aesthetically appealing to destigmatise social housing. The facade indeed looks like waves of meringue.

This case study presents the energy rehabilitation of a facade of a social housing building located in Catalonia through the installation of an innovative, prefabricated, and modular facade system that integrates active and passive technologies and circular economy principles.

Within the REPLACE project, this best practice shows an energy efficient renovation made to an apartment of a 1850 building. In particular, the heating system has been replaced to an air-water heat pump which has allowed to reach energy savings.

The architecture of this multi-functional building strengthens the conditions for a strong inside-outside relationship, enforces human-nature ties and environmental awareness. Dry wood construction and bio-based materials have been used to reduce the carbon footprint. It also uses renewable energy, such as solar photovoltaics, wood boilers and heat pumps.

The Louise Otto-Peters school in Hockenheim, Germany, was the first educational institution to be granted support under the “Efficiency House Plus – Educational Buildings” funding programme. The new build combines three different school types under one roof (a pre-vocational training programme, a vocational upper secondary school and a geriatric nurse / educator training programme) which are attended by up to 280 students in total. The school building is conformant with the Efficiency House Plus standard.

When talking about historical heritage and energy efficiency, many actions may cross your mind: you may think of renovation works, improving insulation, repairing cracking, changing supplies, lighting... Any of these actions are valid, together with regular monitoring of consumption to analyse whether the measures taken are truly effective or not. In Europe, 35% of the building stock is more than 50 years old. Even if they are of a certain age, these buildings, of whatever type, are not considered historic. But of that 35%, a small percentage are buildings with decades or even centuries of history, and which deserve particular attention. In this article, some of the main features of energy efficiency projects in historical buildings are reviewed. The success story of the Art Nouveau Site of the Hospital de la Santa Creu i Sant Pau in Barcelona, a UNESCO World Heritage Site, is shared.

This two family house is a new building and it is a certified passive house in ecological timber construction. The house indeed has been built with regional wood and consistent use of natural building materials. Thanks to energy efficiency measures and renewable energy, the building has very low energy requirements.

This center for construction skills learning has been delivered by EBBA together with the London Legacy Development Corporation. The school provides the opportunity for local people to be sponsored through practical education and training. The results is an innovative and sustainable solution and adapting architecture.

This single-family house is located in Bucharest and is Passive House certified. Indeed, the building has minimal environmental impact due to its extremely low energy requirements. This need is generated by the production of renewable energy: 19 photovoltaic panels are located on the 2 terraces of the building.
