The Kastelli community centre is the City of Oulu's educational, leisure and culture centre. It is the first Nordic school to be awarded the Gold-level LEED for Schools certificate and the Finnish Association of Civil Engineers' 2014 RIL award, is an energy-efficient building that utilises smart building services solutions: each classroom is equipped, for example, with temperature and carbon dioxide sensors, which help control heating and air conditioning. Lighting is controlled by occupancy sensors.
The building is heated by energy-saving underfloor heating. The solution is an excellent fit for sites where the youngest users spend a lot of time sitting or crawling on the floor. In underfloor heating, heat rises evenly from the whole floor area, which means that there is no air circulation or sensation of draft.
Uponor has supplied the Kastelli community centre with underfloor heating on a turnkey basis. The contract included both planning and installation; the latter was performed by Uponor's partner Lakeuden LVI-asennus. Furthermore, Uponor delivered drainage pipes and wells as well as soil and waste pipes to the site.
Uponor planned heat outputs and designed piping and flow rates for the given outputs. During planning, special attention was paid to pipe routes and the heat emissions of underfloor heating in order to prevent excess output.
