Finnish Excursion to Stockholm
Finnish Co2olBricks partner – Kiinko Real Estate Education organised an excursion to Stockholm in April.
One inspiring refurbishment object was the Gaswork area that is part of the city’s vision of a world-class Stockholm by 2030. The historic industrial buildings designed by Ferdinand Boberg in the late nineteenth century will be transformed with the focus on culture, education and retail. The area consists of around 30 buildings, five of which are circular gas holders from three generations of the works. Gas has been produced here for over 100 years. The industrial and urban character of the gasworks, which is of major architectural and historic value, is unique in Sweden. By 2020 over 6000 homes will have been built and Horthagen will have 15,000 new residents. The overall
objective is a climate-adapted and fossil fuel-free urban district by 2030, in which carbon dioxide emissions are lower than 1.5 tonnes per person per year by 2020.
The group also visited the City Hall which is mainly concentrating to improve energy performance on using the Green IT. It aims at reducing the environmental impact with the aid of IT. Tommy Waldnert from the Real Estate Administration told about the refurbisment work that has been done, mainly concentrating on the Green IT.
It involves: 1) using information technology to reduce our environmental impact, and 2) reducing the energy consumption and environmental impact of the IT sector. Heating, ventilation and lighting can be controlled in line with tenant requirements, using IT-based control systems. Actions include development of new technology designed to reduce energy-related emissions, and turning off lights in empty buildings and installing presence control. The major challenge was finding an energy efficient light source that would look similar to the chandelier bulbs and be visually appealing. It should also have clear glass, provide the same warm light and emit an adequate amount of light, similar to the incandescent lamps. All the clear chandelier 40 W bulbs in Prince Gallery have been replaced with an E14 cap base. A total of 126 LED lamps were installed. By introducing LED lighting in the Prince’s Gallery, the installed power has been slashed by 92.5%. Stadshuset is saving over 20,000 kWh a year, a reduction in CO2 emisions of over 2 tonnes.
Totally unknown brokerage organisation to all participants was Stadsholmen. It owns about 280 pieces of real estate with around 1,650 residential buildings. Several of them have the highest protection classification.
The group of a dozen participants consisted of architects, researchers and museum specialists from Finland, Sweden and Germany.
