The Influence of Different Hourly Typical Meteorological Years on Dynamic Simulation of Buildings

This paper presents a parametric study on the effect of different TMY (Typical Meteorological Year) datasets on the results of energy dynamic simulation. The analysis was carried out running the software Design Builder with EnergyPlus code on a sample residential building located in three Italian cities and using two different TMY data sets: EnergyPlus and CTI (Italian Thermo- Technical Committee).

A case study on residential mixed-mode ventilation using the Ventilation Controls Virtual Test Bed

Mixed-mode ventilation uses intelligent switching between natural and (partly) mechanical ventilation modes to find the best possible balance between indoor air quality, user comfort and energy consumption. It applies demand-control at the level of the operating mode depending on the constraints imposed by the building, its users and its surroundings. Although mixed-mode ventilation is said to have the potential to achieve a comfortable and healthy indoor environment while achieving significant energy savings, it is rarely used in practice.
