Simulation of noise, daylight and air quality

Purpose and goal

In our report, we have investigated the possibilities of calculating and estimating indoor noise, daylight and air pollution levels using existing methods, tools and computer programs. We have compiled the knowledge situation and also published two articles that highlighted these important issues. We have found that it is not currently ideal to invest in developing software but that major software developers could invest in a software series that can make these analyses. Ongoing standardisation work in Europe supports this development.

Expected results and effects

At the moment, it is not ideal to invest in developing software. In the long term, harmonisation of noise rules and calculation methods in Europe can lead to major software companies developing computational programs that can handle all types of simulations as per this report. Development work is ongoing in, for example, France and Spain as well as standardisation work that can provide better conditions through coordination of requirements. It is essential to convince Swedish authorities or the EU to clarify the regulations, to justify relatively demanding investments.

Planned approach and implementation

Through literature studies and interviews, we have compiled the current state of knowledge and evaluated the possibilities of carrying out analyses of noise, light and air pollution with existing software, standards and skills. We have also discussed ongoing work on developing requirements, rules and standards in Sweden and Eupopa. We have also proposed new principles that could be indicative of a revised traffic noise regulation
