The COMBI partner Copenhagen Economics has recently published a study conducted for the Swedish Energy Agency and the National Board of Housing, Building and Planning.
Background: The Swedish government is currently in the process of designing a new building strategy, including a program for renovating the existing building stock.
- The value of energy savings is the largest source of benefits from renovations of the Swedish building stock.
- reduced outdoor air pollution can deliver significant benefits. Attributing the value of outdoor air pollution can be difficult, as air pollution is windborne, and may not necessarily give rise to damages in the same area as the polluting source.
- Improved indoor air quality is a large potential source of value for Swedish society. Prevalence of asthma and respiratory diseases, and especially so called sick building syndrome are common undesired consequences of poor indoor air quality. In addition, improved indoor air in schools is likely to improve students’ learning abilities. Taking advantage of these benefits requires that renovations have a broader focus than just on energy savings, and especially on delivering better ventilation and lighting.
