Climate change can seriously impact the energy consumption of buildings by affecting their air conditioning loads inside, especially the ventilation loads, which directly vary with the local weather conditions! Research on how your ventilation load responds to temperature change is of superb implication, especially in coastline subtropical regions… However, the results indicate that temperature warming increases both latent and sensible parts of the cooling ventilation load. The latent part, which occupies about ~72% of the overall ventilation load, increases at a higher rate, roughly twice that of the sensible part. The latent area of the cooling ventilation load while we are in the night, which is the most sensitive component of temperature change, has a significant job in increasing energy consumption. The severity of temperature affects the degree of heating or cooling necessary to condition the incoming air. The greater potential exists for using complex ventilation system strategies combined with heat recovery when ventilation cooling or heating loads are much higher! A ventilation system may be cost-effective in 1 climatic region however may not be ideal in another. The location of buildings further affects the choice of the ventilation system. Regions in the city and urban areas, for instance, can experience poor outdoor air quality derived from industrial and traffic pollutants! In contrast, outdoor noise from passing traffic and daily residing can be excessive, thus restricting the potential for the window opening. Adjacent buildings may create fights in relation to pre-existing exhaust and air intake points. Regions in rural areas might be subjected to fungal spores and high pollen concentrations, resulting in air filtration for hypersensitive individuals.
