natural ventilation

  Transitional spaces are meant as “a space in between indoor and outdoor climate, or between two indoor environments, which thermal characteristics can be or not modified by mechanical control system and where occupant may experience the dynamic effect of this change”. Nowadays, transitional spaces are pivotal in non-residential architecture and the proportion of such areas may vary between 10% up to 40% of the total volume depending on the typology. Mixed-mode buildings are desings with by both active and passive systems.

Ventilation is already present in buildings through mechanical and/or natural systems and it can remove excess heat gains as well as increase air velocities and thereby also widen the thermal comfort range. IEA Annex 62 experts developed guidelines for an energy-efficient reduction of the risk of overheating by ventilative cooling solutions and for design and operation of ventilative cooling in both residential and commercial buildings.

Although EPBD stated that minimum energy performance requirements shall take into account indoor climate conditions, many member states neglected indoor environmental issues while implementing energy conservation policies. As a result, nZEB rush pushed towards high insulated and airtight buildings, which resulted in an increased overheating risk during summer and shoulder seasons in both residential and non-residential buildings.

Natural Ventilation in a Smart Building can remarkably reduce cooling energy demand in temperate climates—to Zero for almost the entire year.   The first part of this webinar will focus on the design and performance of natural ventilation systems through case studies of different Zero-Net-Energy (ZNE) buildings in California that aggressively adopted this design strategy, and used conventional systems. The webinar will also elaborate on what practical problems were encountered and the outcomes—i.e., what were the “lessons learned”.
