Warm Swedish buildings
The Kungbronhusen Office Building is a 13-storey property in the centre of Stockholm, near the Stockholm Central Station.
Both the Central Station and the Office Building are owned by Jernhusen company.
Jerhunsen wanted to prove that it is possible to built a sustainable office building using available of the market materials and mature technologies rather than fancy but risky innovations.
The objective of the project is to create a development where the environment and energy-efficiency are central considerations.
Building’s branding is about being ‘green’: the office space is let to the companies that want to boost their image as environmentally-friendly. All the tenants in the building are supported the expert who helps to adapt the organizations and minimize their impact on the environment. The building is advertised as being ‘eco-smart’, which includes three characteristics:
- Eco-smart building: The building with energy efficient façade and environmentally adapted materials, combined with other innovative solutions that lead to three environmental certifications.
- Eco-everyday: Services and technical solutions that enable users to operate in an eco-friendly way.
- Eco-location; The building’s proximity to public transport makes travelling and transports easier and contributes to lower CO2 emissions.
The users of the building are encouraged to minimize the environmental impact of their daily activities. Building users are offered coordinated framework agreements for cleaning services, servicing of office machinery and waste management. The building is also provided with secure bicycle storage area with a compressor pump and tools available for bicycle repairs, as well as dressing rooms and showers.
Another intersting part of the building is a ‘green button’: This button is pressed at the end of the working day to ensure that all standby functions such as computers, screens and other lighting are switched off.
An important part of the project is the building’s energy-efficient frontage, which controls the amount of sunlight allowed into the internal space and creates a balance so that the interior is neither too hot nor too cold.
One of the interesting features of the building is that every hour the Swedish meteorological centre automatically sends a detailed weather forecast direct to Kungsbrohuset via the GSM network. This means that the heat supply to Kungsbrohuset will be increased several hours before a drop in temperature occurs. By doing this, building’s heat regulating system is put to optimal use.
The largest part of the heating is provided by GSHP, with some part of the heating provided by body heat! Approximately 200,000 people pass through nearby Stockholm Central Station every day. These people, along with the various restaurants and cafés in the station, produce a large amount of excess heat. Instead of letting this heat goes to waste, it now being used for heating. Kungsbrohuset building. The technology is not new and is similar to the principles of Canadian wells. The heat generated by human activity is recovered by the ventilation system and then sent away from the station in its water tanks. Heated by this hot air, the water is sent to the second building through a heat exchanger, which allows the building to save up to 20% of its energy consumption. To complete the loop, the cooled water is returned to the station to optimize its temperature control.
Jerhusen is planning to build some more office buldings around the train station in the nearset future and they also have similar projects in other cities in Sweden.
Does this mean that this kind of projects are easy to replicate and can be widely used in the UK? We will talk about it in our workshop in early February – and if you are intersted, contac tme on k.chmutina@lboro.ac.uk .

£30 million announced for community green schemes and public sector energy efficiency
Energy Secretary Chris Huhne has today announced funding of £10 million for local community energy projects, and a £20 million boost to the existing public sector energy efficiency loan scheme. Chris Huhne said:
"This is great news for the public sector. Not only do we need to encourage energy efficiency in our schools, hospitals and universities, we also need to get green energy generation and energy efficiency into our communities. That's why we are also making £10million available for communities to help spur an energy revolution at a local level."
The new £10 million Local Energy Assessment Fund, managed by a number of community networks and administered by the Energy Saving Trust, will be run as a competition, with the chance for around 200 community organisations to get to grips with energy efficiency and renewable energy generation. Organisations including parish councils, voluntary associations, development trusts and faith groups are all eligible to apply.

Berlin's approach to Refurbishment: Energy saving partnership
I met up with Ms Susanne Berger from Berlin Energy Agency, which is responsible for the implementation of the partnership and also with Mr Klaus Ritcher from one of the ESCOs carrying out the implementation of energy efficiency measures.
Berlin energy saving partnership was first introduced by the State of Berlin in 1995. The reason for developing BESP was to reach Germany’s ambitious climate protection objectives, as well as to reduce energy costs. Its basic principle is simple: a private specialized energy service company (the contractor) brings its know-how and financials means into the project. The responsibility of the contractor is to ensure that by making adequate investments, the energy savings can be guaranteed. Both partners then share cost reductions and profits are also shared between the client and the contractor – while energy consumption is reduced.
Under the current BESP, among refurbished buildings there are school, kindergartens, office buildings, swimming pools, theatre, universities and other municipal buildings. All together around 1,400 buildings have being refurbished with the total CO2 reduction of approximately 69,600 t/a. One of the first refurbished buildings was Berlin City Hall.
The refurbishments have been performed by 17 contractors, and the guaranteed savings were achieved in all contracts. On average the guaranteed savings are around 26% of baseline energy consumption, with the highest energy savings resulted in 35% savings!
Interesting, replacement of the windows and insulation are not a part of the programme - implemented energy efficiency measures include refurbishment of heating and illumination, energy management and what is very important user motivation. I found the last measure – user motivation – particularly interesting: it is a requirement for the contractor to teach the building users about energy savings, and by the end user they do not mean buildings manager. If the building under refurbishment is a kindergarten, then the contractor talks to children as well!
This model has proved to be a success in Berlin and is now widely replicated in other European countries, such as Slovenia, Estonia, Bulgaria, Romania, as well as in China, Chile and other countries. It also expands in Germany and there are plans for implementing “Berlin Energy Saving Partnership Plus” where more expensive measures such as building insulation and window replacement will be performed.
More about this progamme will be presented as a part of our workshop on 27th of January – and we will also look at its potential to be implemented in the UK.

How to heat your house using seawater
The sea water heating plant is part of the city’s plan to use more sustainable energy and is one of the steps being taken towards making the Hague ‘climate by 2050. Today seawater heating system provides 750 houses in the area of Duindorp with heating and hot water; and it is planned to connect further 300 houses to this system. As Mr Henk Heijkers from the City of the Hague Sustainability Department put it, “my dream is that the whole Scheveningen Harbour area gets fantastic new buildings with the new Duindorp all connected on seawater energy”. Duindorp is a new housing estate area along the North Sea Coast built to replace 1100 old energy inefficient houses that used to be small former fishermen family houses built between 1915 and 1931.
The concept of seawater heating system is innovative but simple: it consists of a seawater central supply unit with a heat exchanger and heat pump unit that uses the nearby sea as a temperature source. The technologies involved are not new, but it is the way they were combines that attracts attention: it is an innovation that allows constructing a very efficient system for making seawater or surface water the source of energy for heating homes as well as heating water – and not only during a warmer season.
The idea of a sustainable heating system was proposed by the housing corporation Vestia – it is now an owner of the seawater heating system. However, it took some time to find the most suitable system: for a few months government authorities, housing corporation, engineering consultancy and utility companies were involved in a process of brainstorming and discussion. Eventually, Mr Paul Stoelinga from Deerns came up with the idea of combining a heat exchanger, a central heat pump and small water pumps in the homes. In summer, the heat exchanger feeds heated water to local grid, drawing enough heat from the seawater to cover residents' need. In winter, the job is taken over by the central screw ammonia heat plant. This allows ensuring that throughout the year residents of the Duindorp houses get indoor comfort and tap water at the right temperature.
While in the Hague, I had a tour around the central unit located near the harbour. This small warehouse-looking building contains both the central heat exchanger and heat pump. Smaller individual heat pumps are installed in each home for further heating.
The overall efficiency of the heat generation process with this system is more than 50% better than with conventional high-efficiency boilers, while the cost to the residents is no higher. Moreover, it results in a 50% reduction in CO2 emissions.
Similar system can be installed pretty much anywhere in the world close to the body of water and it would even be cheaper in case of fresh water, because there’s no need to protect the heat pump, heat exchanger and water pumps against salt corrosion. So why not use it in the UK?

The Great Divide between academics and practitioners
During the day a number of themes were brought to the fore, including the perception that academic research usually only finds what practitioners already know, and that academic research is too slow, partly due to funding becoming available too late. Furthermore, funding was perceived to be too project-focused and is often not available to the many spin-offs generated by many successful projects. Another issue was that academic reports often aren’t digestible for practitioners, and that reports and case studies are available in such quantities and variety of places, that for practitioners such as community groups they often are of little value.
Another big issue that was discussed was the uneven relationship between academics and practitioners: practitioners often don’t get enough out of participating in research projects (something to keep in mind in our own case study work!). This, however, could be addressed by cooperation in the research design phase. If this isn’t possible, then perhaps academics should give something back to the practitioners, like sharing certain academic skills, for example by giving a workshop on how to do a good questionnaire/survey. Practitioners should not have too low expectations when contacted by academics for the dreaded ‘hour of your time’ – why not ask for something tangible in return rather than simply deciding on a ‘yes’ or a ‘no’ when asked to participate?
Overall, there was a sense of lack of involvement of practitioners / community groups and a disconnect between what they need to know and what academia is researching. In other words, there needs to be more of a dialogue between both groups. Suggestions to achieve this link-up even included ‘adopt a local authority’, and speed dating to link up the right research needs with the right academics. On this point, a very interesting attempt to bridge this gap has already been made by the Grassroots Innovations blog, where practitioners are called on to get in touch with their research suggestions and ideas. Let’s hope this will prove useful in building on the issues discussed!

From the Planning Research Conference
Another interesting paper came from Germany and looked at cooperatives. Apparently two new energy cooperatives were opening every month in Germany last year. These organisations have climate protection written into their founding charters and can be used for a variety of urban development projects. One advantage is that such cooperatives can access finance, both public and private. An example can be found at www.moeckernkiez.de.

ARUP Scenarios: Renewables 'could provide 35% of energy capacity by 2020'
The research looks at three scenarios for the future operation of renewables – low, medium and high – based on the maximum capacity that could be built per year between now and 2030.
The study looks at a range of technologies including wind, solar, hydro, biomass, geothermal and energy from waste, but does not highlight the benefits of one particular renewable technology.
Arup said that it will be up to government, industry and the public to decide how to overcome the barriers to greater use including planning issues and the costs of connection to the grid.
The study provides a detailed picture of generation costs and deployment potential for a wide range of technologies.
