ISO/FDIS 21075

Design and assessment process of whole-building mechanical ventilation systems in residential buildings

Апстракт

This international standard describes the steps of designing the whole-building ventilation system for
residential buildings and the points to be taken into account regarding the indoor environment and
energy consumption. This standard allows the designer to plan a whole-building ventilator that
improves indoor air quality, the auditory environment, and thermal comfort, and that also uses
energy in a practical way. They also touch on the performance of the building in order to operate a
whole-building ventilator well.

Excluded:
- Criteria for indoor air quality
- Criteria for indoor thermal comfort (covered by ISO/TC 159)
- Criteria for auditory environment (covered by ISO/TC 43)
- Evaluation method of energy performance of heating or cooling equipment
- Evaluation method of energy performance of ventilators (covered by ISO/TC 86)
- Evaluation method of energy performance of heat recovery components (covered by ISO/TC 86)
- Evaluation method of building performance (covered by ISO/TC 163)
- Design steps and evaluation method of localized ventilation equipment
- Ventilation systems using natural driving force in all ventilation airflow path
