21.-25.9.2009 - The Hague/The Netherlands
REBECEE EFL Projects Exhibition
In the period from September 21 to 25 EFL and EFL member Staedion organized one week of activities within the framework of REBECEE - a model home, a congress, a workshop and several study tours:

Climate Construction pilothouse in The Hague realised: Contribution of Staedion, Van der Leij and EFL regarding sustainable Construction

Throughout the month of September, in The Hague a model of an innovative new housing is demonstrated. It is a highly energy-efficient building, constructed via the principles of Climate Construction. Climate Construction specializes in (prefab) building solutions specifically for the construction sector and made of expanded polystyrene (EPS). EPS, better known as Styrofoam, is thanks to the millions of air bubbles enclosed, a very good insulation. The facades of the pilot house are solid EPS. The pilot house is part of the series of activities that Staedion and EFL and organize around the REBECEE Sustainable Week in The Hague and is located opposite the headquarters of Staedion, Koningin Julianaplein 2 in The Hague.

Staedion - REBECEE Jubilee Congress in the context of sustainability and energy efficiency

Under the heading "Future = Now X Sustainability" on Wednesday, September 23 there was a full day conference in the Nieuwe Kerk in The Hague. Housing corporation Staedion celebrated its tenth anniversary, and combined this with a great conference. The congress was dominated by REBECEE. Speakers at the conference included Jan Terlouw, Chairman of Energy Transition Platform for Built Environment (PEGO), Elco Brinkman, chairman of “Building Netherlands” and Marnix Norder, Deputy of The Hague. During the discussion section also Fons Catau, director of EFL member De Woonplaats gave his vision on the future of sustainable housing and Staedion Director Willem Krzeszewski concluded the congress and discussed what is learnt and which tasks Staedion has set for itself.

Pilot projects

“De Koningsvrouwen van Landlust” now in realisation. 100-year Anniversary Eigen Haard startshot for renovation

After two years of preparation time, on September 8, 2009 Eigen Haard started the realisation of the famous project “ The Kingwomen of Landlust". This date is not arbitrary. It coincided with the 100th anniversary of this great Amsterdam housingcorporation Eigen Haard.
The project Landlust consists of two monumental buildings from 1937. Architect Merkelbach designed this complex, based on then revolutionary techniques such as a steel skeleton and steel windowframes. Then known as “Modern Building”. The building has a monumental status, what is a special challenge for Eigen Haard. While maintaining the facade (the outside) as it is, the building will be insultated the next years on the inside. Modern, energy efficient dwellings will be realised. Sustainable generated energy for heating provides a significant proportion of the required heat (heat pumps, possibly a woodpelletsysthem). The houses are also equipped with heat-recoveryunits, which ruese the heat in the building. The renovation plan developed within the EFL context is an example of how the future for Eigen Haard will be. Sustainable redevelopment of the housing stock has a high priority. Unique is also the plan development itself: many experts, including experts from Germany (Passive House experts of the Energy Technology Centre (ETZ) in Nuremberg contributed. The success is especially great by the input of the residents in the design process. This was of decisive importance.

Project Balkengat adapted to market conditions:
EFL Expertise delivers new features to market new innovative energy project

The plan for building 14 innovative Climate Construction homes in one location in central Delfland has a new impetus. By the deteriorating situation on the Dutch housing market, the original plan was not feasible. The clients, the EFL members Staedion and Van der Leij Construction have requested an alternative plan. EFL Expertise parcelled a new plan in order to make it market feasible. In the new plan, the main characteristics keep upright: 10 semi-detached houses and a 4-row houses for starters will be developed. The Climate Construction principle, with facades and interior walls are made of high quality EPS, provides an energy efficient and comfortable interior, while the strength is not inferior to traditional building methods. The standard energy request approaches that of the German Passive House Concept.

Com Wonen-project Dotterlei “Het Truweel” to be continued

European exchange of knowledge between experts in sustainable building has a new success. In Capelle a / d IJssel, the Rotterdam housing Housingcorporation Com Wonen decided to renovate one of his flats on the basis of the German technology of “Factor 10”. After two successful organized trips by EFL Expertise to Hamburg and Nuremberg, there is chosen for a renovation plan based on the target for energy consumption for space heating up to 90% reduction. Factor 10 is the starting point. Examples of the EFL members Joseph Stiftung and WBG Nuremberg have served as inspiration for the project "The Truweel. The draft provides the elimination of all cold bridges through the removal of existing (concrete) galleries and the thermal decoupling of new galleries and balconies. This allows the entire building for a transition into a properly insulated flat. The houses are equipped with an energy efficient ventilation system with heat recovery. In Germany, convincing examples of effective ventilation systems for usability and comfort were investigated.



First step towards participation of EFL into the REBECEE project was taken in 2007. From 1-10-‘07 till 24-12-‘07 a student of Eindhoven University of Technology fulfilled a traineeship at ZEBAU, Hamburg. His research ‘Energy Efficient building and renovation’ led to a better understanding for EFL of the problems concerning Renewable Energy applications in building. After this period EFL decided to participate as an Observer in the project. In June ’08, the decision has been taken to participate as a full member in the REBECEE programme. An overview of the activities that have been undertaken is provided:

From 10-12 November ‘07 a seminar for EFL members was organised in Hamburg. Representatives of Dutch housing associations visited Hamburg for a programme which consisted of plenary sessions and excursions towards energy efficient and renewable energy appliances in Hamburg.

In January ‘08 EFL member Eigen Haard started the project ‘De Koningsvrouwen van Landlust’ in Amsterdam, NL. The project aims to renovate a 1930 housing block consisting of 245 dwellings. In this project, possibilities for increased energy efficiency of the building envelope will be researched, as well as the application of renewable energy. The building will be declared a monument by the Dutch state. This will challenge the design team to come up with an innovative solution, in order not to harm the monumental status.

In January ’08 EFL members Staedion and Van der Leij Bouwbedrijven started a research in order to increase the energy standards and the implementation of RE of the building project ‘Hoornsche Vaart’ in Den Hoorn, NL. The project consists of 14 houses which were designed according to the national building codes. The goal is to realise houses which consume significantly less energy than traditional housing. The remaining amount of energy is produced by RES.

The 28th February ’08 a lecture about energy efficient building and RE was given to the board of EFL by a junior consultant of EFL. The lecture was focussed on the differences in dealing with energy consumption in the built environment between Germany and The Netherlands.

Eigen Haard is planning a training course in passive house designing for own employees and external experts. The training course is due to take place in fall 2008.

Staedion, the EFL member from The Hague, NL, is taking part in a consortium “Aardwarmte Den Haag v.o.f.”, which is developing the first Geothermal Energy project in the Netherlands. In the upcoming years, 4000 new built houses will be provided with heat that is gained at 2500 meters below sea level. This means a reduction in CO2 emissions of at least 4000 tonnes per year.

EFL member Com Wonen is currently executing a feasibility study for energy efficient renovation of a block of 49 dwellings in Capelle a/d IJssel, NL. Appliance of RE will be included in the research. Com Wonen is contacting the local authorities to match the project with the Climate Protection Programme of the municipality. The project is due to start in September ’08.

At 12/13 June ’08 EFL introduced itself to the REBECEE partners at the 4th Clustermeeting in Tallinn. The proposed projects for the Building Exposition were presented. In the upcoming period, a detailed concept for the Building Exposition will be developed. The Building Exposition will be organised in summer/fall 2009.
