Abstract : An investigation of correction of defects, as Energy Conservation Opportunities (ECOs) in HarmonAC project, can be done to fulfill two objectives: to improve thermal comfort and to reduce energy consumption of buildings. Among defect correction, HVAC control appears as a way of significant improvement. HVAC control is examined by using a dynamic simulation to improve the management of HVAC system for two opportunities: centrally, one opportunity is to sequence better Winter and Summer mode; locally, another one is the modification of internal set points to adapt to external climatic conditions. Adaptive comfort is examined to develop new rules for local control. Energy impact and thermal comfort of these two ECOs is investigated in the paper. An analysis of thermal comfort criterion shows that applying the operative temperature of EN15251 increases the consumption of the simulated building compared with a simple temperature control. According to our definition of heating and cooling modes, a good management of water network pumps for a four pipes system can reduce their consumption by 33%. A method to determine heating and cooling seasons is proposed to provide sufficient thermal comfort. A proposal to model the reasoned use of air conditioning equipment are investigated, it achieves a good thermal comfort and reduces the cooling load by 7% for Liege location.
