Rationale behind ventilation requirements and regulations

Duration:

2016-2021

Status:

Completed

Internationally there are many different requirements and regulations for ventilation. Sometimes the variation is more than a factor of five. There are strong drivers to reduce energy consumption for HVAC, and therefore the spread in requirements and regulation is worthwhile to study. To reduce ventilation flows there is a necessity to understand the reasons behind. Demand control to reduce this flows is in many countries growing but the control parameters are quite different, for instance humidity versus CO2 control. If you don’t know the reasons for ventilation, you cannot decide when and to what level you can reduce the ventilation flows.

The goal is:

to collect information about the rationale behind ventilation requirements in different countries
to analyse these data, differences, similarities
to categorize them .for instance climate conditions
recommendation based on latest research findings
