The energy efficiency project carried out at the Maalaistentalo, located on Simonkatu in the centre of Helsinki, involved renewing the building services automation system, ventilation and lighting. In addition to reducing the energy costs, the building technology was modernised resulting in a reduction in carbon emissions of 79 tonnes per year. The renovations also reduced the repair debt of the property and improved the internal air conditions.
Maalaistentalo was built in 1921. Representing the simple red-brick classic style of the 1920s, over the years the building has housed Valio, Hankkija, SOK, Osuuskassojen Keskuslainarahasto, Lähivakuutus, Tapiola, and Marttaliitto.
