Improvements in Demand-Controlled Ventilation to Reduce Energy Use and Improve Indoor Air Quality
Alonso, Maria Justo (Doctoral theses at NTNU;2022:363, Doctoral thesis, 2022)Buildings have become more airtight and insulated over the last years––a response to the acute need to reduce building energy demands in cold climates. However, to secure satisfactory indoor air quality (IAQ) this has led ... -
Indoor climate in a zero energy building - An analysis of the thermal environment and indoor air quality
Søgnen, Odin Budal (Master thesis, 2015)Buildings are responsible for around 40 % of the world s energy use, hence also for huge amounts of climate gases, both directly and indirectly. The building industry needs to become a part of the solution of an energy ... -
