Low energy day care centres through EPC, Porvoo, Finland

In 2010 the City of Porvoo initiated a project to develop a day care centre based on the consideration of the full life cycle of the building. A central aim of the project was additionally to enhance competence  amongst city procurement staff in handling life cycle objectives within a construction project. Clear project goals were set relating to energy efficiency other sustainability aspects, and in establishing long term contractual relationships.

The contract was awarded through the competitive dialogue process, which involved seven contractors. The procurement procedure required allocation of time and resources, but all parties found it worthwhile in optimising arrangements.

The contract was made between three parties: the city of Porvoo as the building owner, a finance company to provide the  funding, and the service provider responsible for design, construction and maintenance  for  the following  20 years. The service contract established guaranteed limits for heating energy and electricity demand, as well as payment and funding terms and price risk. Energy demand was ultimately set at 40% lower than the original goal set by the city. This will be annually monitored. Another sustainability requirement was flexibility for alterations if the user needs change.
