Good In­door Air as a Service

Smart & Clean Indoor Air

Cities, business and research institutes developed solutions and operating models that allow indoor air to be improved and enable the provision and procurement of good indoor air as a service. Understanding on the components of good indoor air was increased through measurements and new methods.

Leo Hakkarainen: “The energy efficiency of buildings should be developed under the conditions of indoor air”

“Nearly 40 percent of all energy used in Finland is consumed in buildings. In order to reduce this percentage, we first have to understand how energy is actually consumed in properties. When all the building’s data is on one platform, it’s easier to improve e.g. indoor air with it.”

What is it all about


Air quality as a service. Better understanding of the components of good indoor air helps to allocate resources, supports decision-making and leads to new solutions.

Better quality of life

Millions of people’s everyday life can be improved by solving indoor air quality problems.

Business potential

The business potential of the project has been estimated to be hundreds of millions in Finland and billions of Euros globally.


Good indoor air as a service concept is a novel approach to a globally common problem.


Collaboration between cities creates the basis for companies utilising indoor air information to develop their own service models and increases the ability to develop know-how into commercial solutions.


Air quality measurements were taken in over 20 buildings in the Helsinki metropolitan area. At the same time, research was conducted on how people experience air quality. This information was combined to create criteria for good indoor air.

The project created a sensor and feedback infrastructure that produces data which can be brought to service platforms specific to each city or shared by them. The air quality sensors will remain in most of the buildings.

The next steps

The indoor air quality measurements and collection of user feedback started in the project will be continued.

Project goal

The change project developed the concept of Good Indoor Air as a Service. A better understanding of the components of good indoor air and indoor air conditions was achieved through effective measurement tools and methods, as well as defining the criteria. The development platform consisted of 20–30 new or renovated buildings in Espoo, Helsinki and Vantaa. The goal of the project was to give rise to an ecosystem that creates new solutions, services, operating models and export concepts that produce better indoor air.

Understanding the quality components of indoor air will make it easier and more cost-effective to procure, produce and maintain good indoor air in the future. The user of a property can set quality standards for indoor air or the maintenance company can provide good indoor air in the same way as energy efficiency is sold today. In addition, open research data generates new business.


The change project was led by VTT and the project partners were the cities of Helsinki, Espoo and Vantaa, as well as Aalto University. The project received AIKO funding awarded by the Helsinki-Uusimaa Regional Council for launching regional innovations and trials. The cities of Helsinki, Vantaa and Espoo were also co-funders of the project.
