Ventilative Cooling is an airborne system to utilize air from outside at its actual temperature and humidity. Air transfer may be by natural, mechanical or hybrid means. Natural ventilative cooling is an aspect of ventilative cooling whose operation is based … Continue reading →
Yes, ventilative cooling can reduce the cooling capacity of active cooling if both cooling strategies are used alternately and not running simultaneously, for a given room of space. The switch point between ventilative and active cooling can vary between parts … Continue reading →
Yes. A ventilative cooling potential tool (VC Tool) was developed within IEA EBC Annex 62 to assess its potential by taking into account climate conditions, building envelope thermal properties, occupancy patterns, internal gains and ventilation needs. This tool calculates the … Continue reading →
Yes, for example: Austria, Denmark, Switzerland, Belgium , France and Germany. The way ventilative cooling is taken into account in legislation varies among the countries and also between the type of buildings (residential vs. non-residential). References: [1]Plesner C., Status and recommendations … Continue reading →
The Energy performance of buildings directive (EPBD) stimulates the use of passive techniques such as ventilative cooling, aiming to reduce the energy needs for heating or cooling, the energy use for lighting and for ventilation and hence improve thermal and … Continue reading →
Benefits obtained through ventilative cooling include: Reduction of the need of cooling capacity (kW) Reduction of the cooling energy consumption (kWh) Reduction of the CO2 emission Comfortable or lower indoor air temperatures in case of a cooling demand
Continue reading →IEA ECB Annex 62 Ventilative Cooling has summarized the appropriate ventilative cooling principles for different outdoor climatic conditions (Table 1). For differences between indoor comfort and average outdoor temperature between -10°C and 2°C, ventilative cooling is an attractive strategy. Supplementary … Continue reading →
The following critical limitations are mentioned in the work performed by IEA ECB Annex 62 Ventilative Cooling [1]: Impact of climate change on the cooling potential In the next few decades, in Europe (from South to North), extended periods with … Continue reading →
There is a wide range of ventilative cooling principles, and their application depends on climate and microclimate, building type, ventilation approach and user expectations. Depending on possibilities and limitations in the actual case, the ventilative cooling (VC) system may come … Continue reading →
Ventilative cooling on its own may not be sufficient to avoid overheating problems and maintain a good thermal indoor environment during heat waves. The effectiveness of ventilative cooling is strongly dependent on the building's design, the local climate, and the … Continue reading →
