Energy renovations would reduce heating emissions in Helsinki Region by 90%

News 15.01.2020

Supposing 80% of residential multi-storey buildings in the Helsinki Region built in 1960s, 1970s and 1980s were renovated as energy efficient (energy demand for heating max. 40 kWh/m²), emission reduction potential would equal approx. 87% reduction compared to current emissions of the buildings, circa 303,000 tonnes CO₂e per year. That equals annual emissions of over 74,000 residents of the Helsinki Region.

The Renovation Leap change project produced new qualitative objectives and innovative procurement models for repair construction. There is a need for new solutions, since the maintenance backlog of the Finnish building stock will rise to up to 30–50 billion euros.

The Renovation Leap change project addressed the challenges of repair construction, both in terms of quality of construction and practical measures. The new solutions will help to, for example, shorten the duration of renovations, reduce the cost of repair, and make the lifecycle of properties smarter and more energy-efficient.

“If we learned how to repair buildings more efficiently, it would benefit both people and the environment. Renovations would be shorter and improved energy efficiency would reduce the environmental burden”, says YIT Talon Tekniikka’s Development and Marketing Manager Tommi Vienonen

The project brought together rental housing companies and repair construction solution providers. The workshops provided rental housing companies with information on what kind of new solutions are available in general. The solutions presented were related to, for instance, energy efficiency and streamlining pipe renovations. 

“The great thing about the project was how we got the different parties involved in repair construction at the same table. But of course, there could have been even more experts involved from different fields, such as designers and contractors”, says Vesa Jurmu from Helsingin kaupungin asunnot (City of Helsinki apartments). 

Helsingin kaupungin asunnot (Heka) was one of the companies that provided test locations for the project. The new solutions were also tested in the properties of Kojamo and Lahden Talot.

One of the key goals of the Renovation Leap project was to improve the quality of repair construction. VTT created a tool that helps set clear qualitative objectives for repair construction, both for the construction phase and the end result. Heka plans to use the new tool in their new construction contract.

“We are launching Heka’s first renovation project to be executed as an SR (Design and Build) project. In the project, we have the opportunity to use the repair project objective Excel tool developed by VTT. This tool can also be used in other upcoming repair projects”, Vesa Jurmu says.
