Monitoring capabilities of energy management systems in commercial buildings
The Konsolen building is a high thermal mass 57-unit apartment building on the outskirts of Stockholm, Sweden. It is part of the Stockholm Project, a full-scale demonstration of energy-saving techniques. A large number of sensors were installed in the building for research purposes. However, they may not be needed for some types of analysis. It is of interest to see what could be learned if only typical Energy Management Systems (EMS) outputs were available. These include total electricity use, heat output from the heat pump, and heat supplied by the district heating main. It was found that the detailed sensors were essential in debugging the mechanical systems initially, but the EMS-type outputs are quite adequate to confirm that the building continues to operate normally. The building has such stable lumped parameters (average temperature, base load and thermal resistance) that detailed data are not needed to predict the average daily heat demand to within +-10%. However, neither the effect of the solar collectors nor the thermal mass of the building are visible in the EMS-type data. 3 refs., 4 figs., 1 tab.
