The worldwide changes – ageing, climate change, internationalization, urbanization – will

affect the future of built environment. As movement of people has increased, prevention

and management of spread of infectious diseases are important. Based on the Living Lab

research results in HYGTECH2 project, a HYGTECH concept which combines different

technologies related to all indoor elements (air, water, surfaces) was developed in order to

create a comprehensive solution to increase the level of indoor hygiene during the whole

life-cycle of the building.

To support the concept development, the Living Lab research work that was started in

HYGTECH project continued in HYGTECH2 project concentrating especially on microbiology

of ventilation systems, surfaces and water systems. In this report, recommendations

to improve the hygiene in each of the above mentioned section are presented. In addition,

the basis for acceptance procedure of HYGTECH products was developed in this project.

Also the proposal for classification of hygienic indoor environments (H1-H3) was developed,

in which hygiene promoting practices and solutions are integrated with central elements of

the already existing Classification of Indoor Environment. In the future, this hygienic classification can be used to support the space planning in buildings.

The aim of this developed multi-sector indoor hygiene concept was to build up a comprehensive solution, which customer value is based on the combination of products, servicesand knowledge. No single actor can achieve this customer value alone. The indoor hygiene concept has been developed in collaboration with the whole project network. The research performed in the Living Lab real estates has provided valuable information both on products’ technical properties as well as on their usability in real life environments.

HYGTECH is a solution to increase the level of indoor hygiene during the whole life-cycle

of the building. HYGTECH concept is comprised of three modules: Building Services Solutions,

Surfaces and Furniture and Services. The extent of the concept is defined together

with the customer and it varies based on customer needs.

The research institutes participating in HYGTECH2 project were Satakunta University of

Applied Sciences (SAMK), WANDER Nordic Water and Materials Institute; University of Turku,

Turku School of Economics, Pori unit; and Tampere University of Technology, Electronics

and Communications Engineering, Rauma unit. The project was financially supported

by the National Technology Agency of Finland (Tekes) during 8/2013 – 10/2014.
