VIIKKI BUILDING, EKO-VIIKKI, HELSINKI, FINLAND
Eko-Viikki is an ecological suburb in the district of Viikki, 8km north of the centre of Helsinki. It is the fi rst ecological neighbourhood to be built in Finland and has created 64,000m2 of living space for 1,900 residents.
WSP provided structural engineering services for the construction of the Viikki building at the University of Helsinki in Eko-Viikki The brief was to make the 6,500m2 building as energy effi cient as possible, targeting a total energy consumption of 70kW/m2/year, making it the offi ce building with the lowest energy consumption in Finland. The tenants are Finland´s environmental administration, who by the nature of their work were keen to have a headquarters that exemplifi ed an energy effi cient offi ce space. The building will be completed at the end of 2011.
WSP provided modelling and analysis of air tightness and thermal insulations. Our solutions included:
• Cooling systems powered by geothermal energy, taken from long holes drilled through to the rock bed
• Solar panels covering the southern facade • Natural light in the inner parts of the building achieved through the use of light shafts • HVAC automatised so that at evenings and weekends energy consumption is reduced
• Connecting the building to district heating and ensuring all offi ce devices are energy class A.
The site also benefi ts from excellent public transportation connections. The end benefi ts to tenants will be a highly energy effi cient offi ce space with low operating costs.

NEW SOUTH GLASGOW HOSPITAL, GLASGOW, UK
New South Glasgow Hospital has been designed to provide acute and paediatric care. The local NHS board set tough energy, carbon and sustainability requirements for this £600 million hospital. These requirements included a “beyond best practice” carbon target of 80kg/m²/ year, BREEAM Excellent as a minimum, and various socio-economic sustainability targets including local community engagement.
We supported Brookfi eld Europe in its competitive bid to develop this new hospital in Scotland. WSP provided sustainable design guidance and advice to all members of the design team and the resulting design brief presented to the NHS board was judged as “going beyond expectations”. As part of this successful bid, WSP
produced a sustainable design brief which included all the sustainability-related interventions, including off-site prefabrication, use of thermal mass, an on-site natural gas CHP and re-use of demolition elements. It included all 10 of the SHINE key principles for healthcare buildings. SHINE is a learning network for sustainable healthcare buildings and principles developed as a partnership programme between leading healthcare, sustainability and built environment organisations.
WSP’s sustainability project management role provides reassurance to Brookfi eld and the NHS that sustainability is incorporated into the design. We will also carry out a BREEAM pre-assessment and a quality assurance role to ensure the energy modelling is addressed robustly.
The hospital is due to be built by 2015.
The Viikki Building in Helsinki will be the most energy effi cient offi ce in Finland.
