House renovations projects as information source

Demonstration projects are a source of information on technical possibilities, approaches, innovative applications (technology & organization, business, …) and can show the feasibility of certain ambition levels, eg. in achieving very low energy consumption in renovation. Therefore, within the One Stop Shop project, several cases were documented in order to further disseminate the lessons learned in the projects. Frontrunner projects can also be a ‘tool’ for professionals to show and communicate their skills in the field of deep renovation.

In these cases, often new technology is applied, or the concept as a whole is innovative, or interesting to learn from. The cases give an overview of the potential (including benefits, risks, …) for deep renovation, in different contexts, with a high quality standard.

From a selection of the existing projects, a documentation leaflet is made, to communicate different aspects of the renovation project (technical measures, motivation, strategy, …). To select some representative cases, a reference to the report on Building typologies was made. Also characteristics on energy consumption etc. were taken into account.

Based on these criteria, the following best practice examples are documented: 

Row Houses

 

Deep renovation of a row house in Torhout, Belgium

The main goal was to obtain a very low energy consumption by renovation with new techniques and materials. Achieving very good results goes hand in hand with a ‘minimalistic’ architecture: a flat façade. Read more ...

Renovation of 5 social row houses in wachtebeke, Belgium

The main goal was to evaluate the technical and financial feasibility for a social housing company to transform the existing stock into a very energy efficient housing park. Read more ...

Renovation of a terraced house in Antwerpen, Belgium

The owners decided to renovate the house to increase the comfort and reduce the energy consumption. In the first renovation the energy aspect was not considerate. Afterwards they decided to do an energetic renovation in two phases according to the priorities. Read more ...

Renovation of a large urban terraced house in Eupen, Belgium

The owners were looking for a terrain to build their dream house. After searching without a satisfactory result, they decided to buy this house in the centre of Eupen. Read more ...

 

detached houses

 

Deep renovation of a semi-detached house in Ulvøya, Oslo, Norway

The main goal was to obtain a very low energy consumption by renovation with new techniques and materials. Achieving very good results goes hand in hand with a ‘minimalistic’ architecture: a flat façade. Read more ...

Renovation of a sub-urban detached house in Lo, Belgium

“There is an interesting motivation to do this renovation according to the passive house standard: To show people that it is possible." Read more ...

 

High rise appartments

 

Deep renovation of a high rise apartment in Antwerpen, Belgium

When the owner was looking for a house, she had several condtions in mind. With the high real estate prices in mind, she wanted to find a dwelling that would fit these conditions: Read more ...

 

LCC / LCA

Within the research project, several renovation cases are analysed with life cycle costing (LCC) and life cycle assessment (LCA) methodologies in order to document the cost effectiveness and the environmental impact of different renovation scenarios and verify the feasibility of obtaining a Nearly Zero Energy (NZE) level in renovation.

 
These case studies were analysed in the document entitled "Optimal renovation strategies from environmental and economic viewpoint LCC and LCA analysis of demonstration projects". You can find the document here:
