Residential quarter as an innovative source of renewable energy

Asuntosäätiö, Fira Oy, the VVO Group and Helen Ltd have joined forces in the planning of a diverse residential block in Kalasatama in Helsinki with an objective of taking housing quality and energy efficiency to a whole new level of standards. In the so-called SunZEB plus energy model, the excess heating load of the sun on the buildings, which has been problematic in the current construction methods, is turned into an opportunity where buildings are used as a source of renewable energy.  The construction of the first houses will start in 2018.

In the new concept, large window surfaces bring the light and heat of the sun indoors in an optimal way in the summer and winter. In the summer, the energy of the sun and other waste energies are recovered and the excess heat is utilised with the district cooling system in Helsinki’s district heating network. In the winter season, the rays of the sun coming at a low angle heat the rooms and bring plenty of natural light into the homes also in the greyest days of the year. The solution provides an opportunity for a high comfort of living in all seasons.

The block to be part of the city-level energy solution

– Housing plays a key role in climate change mitigation. We must rapidly move from building-specific energy-saving solutions to regional, resource-wise and increasingly energy-efficient concepts. Therefore, we find that the implementation of this pilot project in the block concept is an extremely important step forward, says Development Manager Jouni Kivirinne of Helen Ltd.

In Helen’s SunZEB model, the energy flow in the consumption and production of energy is examined at a broader level than in an individual building. Regionally, the use of primary energy and the CO2 emissions will be considerably lower than in solutions where the thermal and cooling energy is produced and consumed individually at each location. That way, the use of local renewable energy will increase and the emissions will decrease.

The housing block structure in Sompasaari in the district of Kalasatama is a perfect choice for SunZEB construction. Technically, the application of the model will not automatically require a regional overall solution, but it can also be implemented one site and building at a time.

The contractors Asuntosäätiö, Fira Ltd and the VVO Group will each build their own properties in the same block.

Comfort of living with solar architecture

In the design of dwellings, the SunZEB model enables the use of large window surfaces without compromising on a pleasant indoor environment. The new way of utilising solar architecture in the block will make the most of the fantastic sea and park views. Residents will be able to enjoy the light and the views to the full.

Smart energy solutions of the future are tested at Kalasatama. A sustainable, low-energy energy system with services will be created by combining the latest energy, information and communications technologies. By 2040, the district will have 25,000 residents and 10,000 jobs.

New fast route complements Helsinki cycling network

A new fast cycling route now serves Helsinki cyclists. The route ­runs along the main railway tracks. Called Pohjoisbaana in Finnish, the bikeway connects southern and northern cycling routes in Helsinki. It is a part of the network of bicycle superhighways, that is, bikeways with wide lanes and no or few stops, allowing for higher speeds and smoother rides than regular bikeways.

Four groups chosen to continue to the next stage of the Helsinki High-Rise Design-Build Competition

Helsinki is one of the fastest growing cities in Europe. The change in the city is particularly visible in the former harbour and railway areas, which are now undergoing reconstruction to become homes, commercial spaces and business premises. The transformation offers excellent opportunities for property developers.

Myllypuro is a success story of urban revitalization

Over the last ten years the eastern Helsinki district of Myllypuro has experienced noticeable growth. The housing types have diversified and services expanded as a result of systematic development efforts.

“The diversification of housing types, including more housing alternatives for families, is an outcome of infill construction. The Wooden Myllypuro area is a good example of this. The area, also thanks to its predominantly wooden houses, expands the image of Myllypuro,” says Helsinki Mayor Anni Sinnemäki.
