Abstract | After the renovation the building was equipped with Taloinfo, a new energy and comfort online reporting system. It collects hourly measured data from the building technical systems and reports comfort and energy efficiency for employees and visitors in the building as well as for maintenance management. Taloinfo is developed by Granlund in a collaboration with Senate properties. The reporting is on a high level to indicate, if the building is behaving correctly compared to energy and comfort targets.

Lessons learnt | The implemented BuildingEQ data gathering and analysis could confirm that the operation was correct on a more detailed system level. Through BuildingEQ analysis some submetering (what is included in which metering area and how the cooling electricity is measured) errors were found. Results of the Building EQ project - Energy saving potential in the operation of buildings 5 - 30 % - Realisation of these potentials with low or no investment costs - BuildingEQ methods and tools allow quick and cost efficient detection of these potentials - Ongoing performance evaluation is prerequisite for energy efficient operation - Consortium suggests amendment of EPBD with mandatory performance monitoring
