Helsinki offers housing companies energy renovation advice

Energy renovations mean measures taken to improve the energy efficiency of a building or adopt renewable energy. In a housing company, this can entail an installation of a heat recovery system, adoption of geothermal heat or improved insulation during upgrades to the buildings’ facades, to name a few possibilities.

In the best-case scenario, energy renovation measures can halve a Fin nish housing company’s heating costs, thereby significantly lowering the cost of living. Blocks of flats built before the 2000s are typically able to benefit the most from these renovations.

‘Not everyone is aware that energy renovations can often be carried without increasing the maintenance charges due to the work, as the entire project can be funded with the resulting savings. The reduced heating bill will generate savings over time and the value of flats will go up,’ says Team Manager Aleksi Heikkilä.

Last year, a new team of energy specialists was established in Helsinki’s building control services, and its role is to provide housing companies with impartial advice on how to promote energy renovations. According to Team Manager Heikkilä, housing companies can ask an expert to participate in their board meetings to discuss ways for a housing company to reduce its energy consumption.

‘Quick measures to reduce energy consumption include lowering the indoor temperatures, ensuring that windows and doors are properly sealed, and reducing the use of water. However, the most significant savings can be achieved through energy renovation measures,’ says Heikkilä.

A record-breaking number of new geothermal wells

Since being established a year and a half ago, the team that provides energy advice has been contacted by more than 350 housing companies. The contacts that have been made illustrate that housing companies are particularly interested in geothermal heating, and a record-breaking number of permits to drill geothermal, i.e. energy wells, have been granted to constructors in Helsinki this year.

Geothermal heating projects promote Helsinki’s attempts at becoming a carbon-neutral city, and the intention is for this form of heating to cover 15 per cent of Helsinki’s heating needs by 2030. However, at the end of 2021, geothermal heat only accounted for less than two per cent of Helsinki’s heating energy.

In order to promote renovations connected to geothermal heating, Helsinki decided earlier this year that, under certain conditions, housing companies may place their energy wells in areas owned by the City if they lack the necessary space within their own properties.

Housing companies play a key role in Helsinki’s climate efforts

Since Helsinki has a very high proportion of blocks of flats, the energy efficiency measures and energy renovations of housing companies play an essential role in reducing emissions and mitigating climate change in Helsinki and the rest of the country.

The energy consumption of buildings is the largest source of carbon dioxide emissions in Finland, and therefore energy renovations are the most effective form of climate action that a housing company can take.

In order for Helsinki to accomplish its goal of becoming carbon-neutral by 2030, housing companies will need to launch hundreds of energy renovation projects every year. This autumn, the City will run a campaign and encourage all housing companies to identify the energy conservation measures that could benefit them.

Improving energy efficiency is also a key goal in all of the City of Helsinki’s new construction and repair projects. Buildings owned by the City make up approximately one sixth of all the buildings in Helsinki.
