We sleep more than twenty years during our lives. Sleep is essential for physical and psychological health. Yet, nearly no standards define indoor environmental quality conditions for optimal sleep. In this paper, we present a summary of studies examining the effects of bedroom ventilation on sleep quality. The results suggest that the current ventilation standards for dwellings are inadequate concerning requirements of outdoor air supply rates in bedrooms and need to be revised.

Many differences exist between countries in the requirements and regulations for ventilation of dwellings, offices, classrooms and other spaces. Sometimes the variation of the ventilation requirements for the same building type between countries is more than a factor of five. There are strong drivers, e.g., climate change, to reduce energy consumption for HVAC and therefore these variations are worth examining. Before reducing ventilation rates, it is critical to understand the reasons behind them.
These Guidelines recommend the ventilation required to obtain a desired indoor air quality in a space. The first step is to decide the air quality aimed for in the ventilated space. A certain air quality is prescribed to avoid adverse health effects while a decision is required on the level of perceived air quality aimed for in the ventilated space. Three different comfort levels are suggested. The next step is to determine the pollution load on the air caused by pollution sources in the space.
This paper describes a series of field measurements investigating the ventilation rates and indoor airquality in four newly built secondary schools in England. In these schools each with a differentventilation strategy - measurements and calculations were performed to determine the variation inventilation rates during the school day. All the schools were assessed for compliance with the recentlyadopted Building Bulletin 101 which defines the set of criteria in relation to the ventilation rates andindoor air quality in new school buildings.
