An assessment by monitoring and simulation of the energy savings following a correct management in school buildings
No full textThe energy consumption for the climatization of school buildings is characterized by the energy requirement connected with the strong ventilation rates caused by the high occupancy normally foreseen in the classroom in design conditions. Actually the variability of the presences suggests a careful control of the flow rate on the basis of the real exigencies. In the same way in the design, the technical capitulate normally impose values of the internal relative humidity close to 50%, both in summer and winter. This fact involves a remarkable quota of the latent load with respect to the total load. The modern science of comfort has however showed the possibility to operate in a wider interval of the humidity without compromising the indoor comfort.
The energy savings following a correct management of the plants just in terms of ventilation and humidity control are here presented. The investigation is based on the use of dynamic simulation by a model and by the monitoring of an university building recently realized in Venice

No full textThe laboratory tests already necessary for the calculation of the SEER index are sufficient to
build the efficiency curves in part load conditions required for a correct evaluation of the
seasonal performances of a refrigeration machine installed in a building. This assessment is
fundamental for the extension of the energy certification of buildings also to the air
conditioning period. In this paper this calculation procedure is presented and applied to some
different refrigeration machines
