Introduction to our business units

Safety spaces and data centres
We aim for customers for whom safety factors are important or even a critical and vital condition. Our range of know-how covers energy-efficient and safe data centres and sheltered premises during crises, which are our company’s peak know-how.

“Finland has plenty of old command centres, tele- and shelter premises, which are possible to be modernized for data centre use. The structures in old shelter premises are generally in good condition and they naturally suit very well as safety spaces. With good HVAC-design they can be made modern“, says M.Sc. (Tech.) Markku Lilja, the head of the safety spaces and data centres unit where they produce design services for building developers.

Schools and kindergartens
The control of indoor air quality is the most challenging task for schools and kindergartens. HVAC has to adjust to large variations in people and occupancy rate of premises. Generally the solution to this is segregation of larger entireties according to their functions to smaller spaces. In this way it is possible to easily adapt spaces for various purposes.

“Our target is to create healthy and safe indoor air conditions for children and teachers. Good indoor air is a major environmental act conducive to learning“, highlights M.Sc. (Tech.) Henri Airaksinen, the head of the unit which produces design services for the Helsinki regions public sector.

Offices, hotels and venues
The old set-ups can’t often answer to users growing demands. Also heat loads from people and appliances and the tightening demands concerning energy efficiency sets up its own challenges in controlling indoor air.

“The priority is good indoor air quality and healthy working conditions, combined with a comfortable working environment. Despite the issued demands of modern indoor air quality, the renewal of a HVAC system can also lead to savings. When energy efficiency is improving, running expenses are decreasing“, says HVAC-engineer Pasi Heiskanen. Pasi works as the head of the unit, which produces design services to the private sector property owners and builders.
