CONTROL STRATEGY OF NATURAL VENTILATION BASED ON THERMAL COMFORT AND ENERGY SAVING EFFECT : Measurement survey on natural ventilation Part2

Thermal Comfort in Offices – Natural Ventilation vs. Air Conditioning

Based on both subjective and objective data, a study was carried out in order to identify differences in the perception of thermal comfort of office workers in naturally ventilated and air-conditioned buildings. The analysis of the interviews shows that occupants of naturally ventilated office buildings are significantly more satisfied with their thermal environment than occupants in air-condit...

Effect of opening diffuser and return vent location on air quality, thermal comfort and energy saving in desk displacement ventilation (DDV) system

Many investigations have recently been performed on return vent height and indicate that having 1.3 m distance from the floor is the optimized height for it. In this article, the effect of distance between opening diffuser and return vent on air quality, thermal comfort and energy saving was investigated. According to the results, by increasing the distance between opening and return vent up to...

The role of natural ventilation on reducing indoor radon concentration

Due to the increasing of closed ventilation systems used in buildings, the risk of indoor radon is increased day by day. In this study, we selected two sample rooms to calculate the radon emission coefficient from different levels, radon concentration measured when the natural ventilation was completely closed and compared with the analytical results. The results clearly show the difference in ...

Mediterranean Buildings Refurbishment: Thermal Mass and Natural Ventilation Simulated Control

This paper aims to analyse the state of the art of energy performance simulated control in existing buildings refurbishment. It focuses on the contribution of thermal mass and natural ventilation as strategies aimed at improving passive buildings’ performance in Mediterranean climates represented by three locations, Rome, Neaples and Messina. As for single sided and cross ventilation combined w...
