Tiivistelmä
According to the preliminary research, many underused buildings are using as much energy as actively used buildings, or else the buildings have ventilation turned off to save energy, which is harmful to the building and its users. In addition, there are actively used buildings with unsuitable ventilation for their usage. Research is needed to optimize energy usage and to prevent health problems caused by poor indoor air quality. Optimizing energy usage also lowers CO2 -emissions, which should be reduced to 20% of 1990 emissions by 2050, according to the European Union’s energy and climate strategy.
The goal of this project was to optimize the energy efficiency of underused buildings and the ventilation of actively used buildings. New information and recommendations were formulated during the project for companies and the municipality sector. Sustainable development was the main theme of the project. In addition, equality has been taken into account by providing equal indoor climate for users.
The theoretical portion covers the principles of ventilation and heating. The practical part includes different measurements. The real temperature and electric consumption of the ventilation units are discovered. The interior study includes carbon dioxide concentration, temperature, and moisture content.
The results of the project are the improved energy efficiency of ventilation on demand-controlled ways, and the increased knowledge of optimizing energy usage in the examined buildings. New recommendations have been made for controlling ventilation to reduce carbon dioxide emissions. The results will create guidelines for optimal energy usage, which can be utilized nationally by companies and municipalities to promote energy savings and health.
