A New Era of Re­pair Con­struc­tion

Renovation Leap

Repair construction is being sped up and made smarter through quality objectives, life cycle solutions, procurement methods and service concepts. Prefabricated elements and modular components improve the efficiency of repair construction and reduce the cost of, for example, pipe and facade renovations. At the same time, properties are made smarter and more energy-efficient.

Tommi Vieno­nen: “People and the environ­ment both benefit from efficient repair con­struction”

“Property makes up a large portion of Finnish people’s assets, and yet many buildings are in need of repair. If we were to learn how to repair buildings more efficiently than we currently do, it would benefit both humans and the environment. Renovations would take less time and improving energy efficiency would reduce the strain on the climate.”

– Tommi Vienonen, Development and Marketing Manager, YIT Talon Tekniikka

What is it all about

Emission reductions

Energy-efficient repair construction is the fastest way to produce emission reductions in the current building stock. Applying smart solutions to repair construction also reduces the carbon footprint of buildings.

Better quality of life

The duration of renovations is shortened. Housing conditions improve in old buildings as well, which increases the value of the areas.

Business potential

The housing repair construction market in Finland is worth over seven billion euros. Ecosystems formed by companies can bring new construction solutions to market that shorten the maintenance backlog.


The use of prefabricated elements and modular components in repair construction is still limited. The industry needs testing locations that will help validate functional concepts and forms of cooperation.


The ecosystem formed in the project between builders and the companies providing solutions and services streamlines repair construction through a new kind of dialogue with property owners.

There’s a lot of room for improvement in repair and complementary construction. There’s no lack of things to repair, as the maintenance backlog of the Finnish building stock will rise to up to 30–50 billion euros. The Smart Elements for Renovation Leap change project aims to reform repair construction.

The goal of the change project is to create quick, replicable and integrated repair construction solutions. The solutions are created through collaboration between companies, and public sector actors help with testing them. The project makes use of prefabricated elements, modular components and smart solutions, among other things. They help shorten the duration of renovations, reduce the cost of repair, and make the lifecycle of properties smarter and more energy-efficient. The easily modifiable and replicable concepts can be used in, for instance, pipe and facade renovations.

The demonstration locations help specify and clarify the quality objectives of repair construction, which facilitate, for example, the utilisation of new energy solutions in repair construction. In addition, innovative procurement methods and know-how are developed in cooperation with property owners. The procurement and funding models which have been tested at the trial locations and proved to be good will be made available to all housing companies and property owners.


The project is led by VTT and the project partners are Motiva Oy, Paroc Oy, Pilaster Oy, Salusfin Oy, Oy Timberframe Ltd, Vahanen PRO Oy and Wanderfeel. Demonstration locations for the project’s needs are provided by Helsingin kaupungin asunnot Oy (Heka), Kojamo Oyj and Lahden talot Oy. Other collaborators include A-insinöörit, Asuntotuotantotoimisto ATT, Caverion, Cembrit Oy, Consti Oy, DryIce Oy, Enervent, Ensto Oy, Fixel Oy, Fourdeg Oy, Helen Oy, Hilti Oy, Iisy Oy, Integral Oy, NCC Oy, KONE Hissit Oy, Planest Oy, Raksystems Oy, Ramirent Oy, Residentia Oy, Sato Oyj, SG Elementit Oy, Soficta Oy, Uponor Oy, Valvontakonsultit Oy, YIT Oy and the Ministry of the Environment.

Where are we going

The project started in May 2018 and will last 12 months. Components and other smart solutions will be tested during 2019 in residential apartment buildings in Helsinki and Lahti that are in need of repair. The Smart Elements for Renovation Leap is a Smart & Clean change project in accordance with the Helsinki Metropolitan Area’s growth agreement. It receives AIKO funding awarded by the Helsinki-Uusimaa Regional council for launching regional innovations and trials. Funders also include ARA, the City of Helsinki and the Smart & Clean Foundation.
