Building-specific Energy Production, VTT

Office premises the key to energy-efficiency

Office premises are in a key position in the reduction of energy consumption and introduction of sustainable solutions. VTT operates in 37 office premises, most of which are owned by Senate Properties. Development Manager Esa Halmetoja of Senate Properties says that properties are responsible for some 30 per cent of all environmental emissions in Finland. About half the electricity in offices is consumed by lighting and computers and other IT appliances, while air-conditioning and other building services consume the rest.

Last autumn, Senate Properties launched a two-year electricity-efficiency project in 50 of its organisational premises across Finland, including VTT’s premises in Oulu and Jyväskylä, the Tekniikankatu premises in Tampere and the Micronova and Digihouse premises in Espoo. Senate Properties will soon install their “Iceman” displays in areas such as the lobbies and recreational rooms of these VTT premises. The pilot project provides information and useful hints on the consumption of water and electricity, as well as heating energy. Energy-efficiency is honed particularly in the planning stage of renovations. Energy consumption is reduced, for example, by lighting planning and building services controls and adjustments that help avoid unnecessary cooling.

Building-specific Energy Production Receives a Boost - VTT the Technical Research Centre of Finland builds a test apartment electrified by solar and wind energy

Building-specific energy production solutions are becoming common in the near future. This allows the possessor of real estate to decide whether to use the energy production for transportation in addition to living, or sell it to the electricity distribution network.
VTT has built an energy self-sufficient test apartment in Oulu for the research and development of building-specific energy production. The research environment, which is located in the same premises with Oulu office and used by visiting researchers, is connected to the electricity distribution network. It produces the energy required for living and motoring with its own 40 square meter -wide solar power panels producing 8 kilowatts, and with 5,5 kilowatt wind turbine.
In the future, local power plants could be located in, for example, office buildings, commercial buildings and residential buildings.

An attempt is made to fight the climate change by curbing carbon dioxide emissions. Finland, too, has committed itself to reducing emissions in both energy production and transportation, and will
