…but why in Viikki? 1. LOCATION: Viikki- Nature Reserve Area

Helsinki Master Plan 2002 2. HISTORY – FARMING IN VIIKKI SINCE THE MIDDLE AGES

The history of Viikki Viikki 1993 and the rural landscape have an Helsinki University Faculty of Agriculture and Forestry important role in the founding the City of Helsinki

During the Middle Ages Viikki was one of the most prosperous villages around Helsinki.

Following the city’s Site of Eco-Viikki founding 1550 fields of Viikki were taken from the peasants to the crown.

Since 1946 the fields of Viikki have been used as a University teaching and research facility. Helsinki University Research Farm Today the large farmlands still give character to the open landscape of Viikki. Photo: City of Helsinki/Real Estate Department/City Survey Division

The ecological ideas in Viikki were generated in two open planning competitions.

The first was for the town plan and the second concentrated on the ecological building design.

Ecological Building Design Themes in Eco-Viikki Housing saving energy and water

utilization of solar energy passively and actively

healthy indoor climate

building flexibility

healthy materials + timber building

surface water management

quality of the public streets and parks

- PIMWAG evaluation in each housing project - Pilot projects + design competitions - The cost effect of the basic requirements of the criteria for the price of the dwellings was about 3-5 % - The additional costs will be compensated by lower costs over the life of the building Eco-Viikki – Local Plan 1998- Viikinoja – collecting surface water…

- removed former drainage canal built to resemble natural small river - collects surface-water from large areas - balances flooding peaks - slows down the movement of water and improves the quality of water before reaching the Vanhakaupunki bay - offers living environment for plants, birds, small animals and insects

Surface Water Management – ”green fingers”

rainwaters are collected green finger, infiltration and channeling of in rainwater sewers the rainwater rainwater is infiltrated and/or conducted through piping, ditching to the green fingers and park rainwater ditch or pipe

- on clay soil it is not possible to infiltrate surface-water…

Eco-Viikki solution: -> infiltrating / slowing down surface water through vegetation and topsoil (no tarmac) -> -> leading surface-water to pipes, ducts and infiltration / detention basins - -> gathering surface-water to underground tanks for gardening Eco-Viikki – start of construction 1999- Eco-Viikki

- a finger shaped pattern, ”Green fingers” with farming plots between the housing quarters - almost all the houses directed to south to exploit solar energy - a wind shelter zone, formed by vegetation between the open field and the built up area -> completed 2003…today about 1 800 inhabitants Viikinoja

Eco Viikki Viikki - Solar Energy Projects

SOLAR HEATING PROJECT - Finland’s largest solar heating experiment - supported by EU (THERMIE-programme) - 9 separate solar heating systems - About 400 dwellings within the sphere - Total area of the collectors is 1246 m2 - Almost one-third of the energy requirements for heating the domestic hot water - About 10 % of the annual heating requirements - Different technical solutions - The sun collectors are integrated within the roof structure - The size of one collector is 10 m2

SOLAR ELECTRICITY PROJECT - Solar panels are integrated into the balcony constructions Timber Building Examples Eco Viikki - Monitoring Project (2004) - Pilot project area monitored

- Consumption (CO2, water, heating, electricity) - Fulfilling of the Ecological Building Criteria (PIMWAG) - Interviews (developers, architects, deputy landlords, inhabitants) - The technical descriptions of the projects

DISTRICT HEATING CONSUMPTION WATER CONSUMPTION ELECTRICAL CONSUMPTION weather adjusted specific fuel consumption kWh/m2, 2002 consumption, litres/person/day, 2002 kWh/m2, 2002 ae = apartment, pe = property

Eco-Viikki - Monitoring Project II (2008)

Differences between goals and results in some projects:

Reasons:

- too high indoor temperature - too high pressure in water pipes - problems in air window constructions - (air and thermal flows in constructions)

Solutions:

- optimal adjustments - information for inhabitants and housing managers - better quality control in building construction phase

- the concept of Science park was introduced1986 - first two biocentres were completed 1995 - total 350 000 sqm office space (250 000 sqm finished) - total 60 000 sqm residential housing (50 000 sqm built) Viikki, Science Park 67 The Science Park is the centre of Viikki

- the ’s campus areas - offices - business incubator blocks - Viikki shopping centre - residential neighbourhoods - public buildings and parks

The Science Park specializes in biotechnology and biological and environmental sciences

The Univesity of Helsinki concentrates in bio- technical sciences, agrigulture and forestry as well as environmental and nutritional sciences.

Info-center Korona & Viikki Science Library University of Helsinki in Viikki

Viikki campus is one of the four campuses of the University of Helsinki.

The Viikki Campus is the location of four faculties: University - Agriculture and Forestry - Biosciences - Veterinary Medicine Evira - Pharmacy Infocentre In addition to this, there are two independent institutes and the Viikki Science Library.

The University Campus also attracts an increasing number of businesses to the Helsinki Business and Synergy Science Park. The Finnish Game and Fisheries building Research Institute and the Finnish Food Safety Authority, Evira, have also moved to Viikki. Business and Science Park MTT Agrifood Research Finland and Helsinki City Environment Centre will also be moving to Viikki in the future.

Viikki Synergy Building - Finnish Environment Institute´s Eco Efficient Office Building

Viikki Synergy Building Planning competition 5.5.-8.10.2010 - Finnish Environment Institute´s Eco Efficient Office Building

Assessment criteria of the competition: 1. Ecological sustainability including energy performance and material efficiency 2. Urban and architectural quality 3. Usability (functionality/quality of working environment) 4. Feasibility (economic efficiency and quality of technical solutions)

• Ecological sustainability was measured with energy performance and material efficiency target values:

• Energy performance followed the target of EPBD recast for 2019-2021, nearly zero energy buildings, which is the basis for energy performance target value of 80 kWh/(m2 a) primary energy without tenant’s electricity (all other energy flows included) 80 kWh/(m2 a) per program area corresponds to significantly lower value per net area

2 • Material efficiency was measured in kgCO2/m and teams competed to achieve possibly low value without compromising with other criteria

• Primary energy factors to calculate the target of 80 kWh/(m2 a) were: Electricity 2.0 District heat 0.7

TOP 10 ENERGY EFFICIENCY PRINCIPLES

1. Minimizing outside volume. 2. Excellent insulation of outside shell. 3. Making use of buffer zones. 4. Maximizing daylight. 5. Effective solar protection. 6. No mechanical cooling for offices. 7. Low temperature radiant heating. 8. Efficient heat exchange system. 9. Intelligent adjustable heating and ventilation. 10. Minimizing all use of electricity.

MATERIALS

- The building materials and construction methods have been

selected with the aim of minimizing CO2 emissions. - The main material in the building is wood. The load bearing structure is made of wood with KERTO columns and beams, as well as wooden hollow elements. - Concrete is used only in ground floor and staircase structures. - The outside façade is made of unpainted wood, which turns naturally grey. The courtyard façade is made of paper-plastic composite (UPM Profi), whichis 100% recycled industrial waste. The insulation is made of Ekovilla. Lightwalls inside the building are covered with gypsum board.
