State-of-the-Art for the use of Phase-Change Materials in Tanks Coupled with Heat Pumps
Pardiñas, Ángel Á.; Alonso, Maria Justo; Diz, Rubén; Kvalsvik, Karoline Husevåg; Fernandez-Seara, Jose (Journal article; Peer reviewed, 2017)With the goal of increasing heat storage in the same accumulation volumes, phase-change materials are considered. There are different substances with different phase-change temperatures that can be used for storing heating ... -
Techniques for airflow measurements to determine the real efficiency of heat recovery in ventilation systems
Rønneseth, Øystein; Liu, Peng; Alonso, Maria Justo; Mathisen, Hans Martin (Journal article; Peer reviewed, 2019)Heat recovery in ventilation is essential to reduce energy use and thus mitigate greenhouse gas emissions from the building sector. Heat recovery efficiency of at least 80 % in new buildings is required according to Norwegian ... -
Theoretical Prediction of Longitudinal Heat Conduction Effects on the Efficiency of the Heat Wheel Used for Ventilation in Powerhouse Building “Kjørbo” in Norway
Liu, Peng; Mathisen, Hans Martin; Alonso, Maria Justo (Journal article; Peer reviewed, 2017)The present study investigates effects of longitudinal heat conduction (LHC) on the heat recovery effectiveness of the heat wheel in the Powerhouse building “Kjørbo”. The effects LHC which are usually ignored in the heat ... -
Thermal zoning during winter in super-insulated residential buildings
Selvnes, Eirik (Master thesis, 2017)In the work of reducing the energy consumption of buildings, the passive house concept has been developed as a possible solution. These buildings have a low energy need for space-heating and is therefore often equipped ... -
Utilizing IoT technology for healthy and energy efficient improvement of existing ventilation systems
Jørgensen, Thomas Berg (Master thesis, 2020)Byggebransjen er ansvarlige for betydelige deler av verdens energibruk og utslipp av klimagasser, men er også en av bransjene som er best rigget til å kutte energiforbruk og utslipp mest kostnadseffektivt. Behovsstyrt ... -
Utilizing IoT technology for healthy and energy efficient improvement of existing ventilation systems - Case study of indoor air quality in a primary school classroom using Arduino sensors and CONTAM simulations
Jørgensen, Thomas Berg (Master thesis, 2020)The residential and commercial building sector is responsible for a substantial amount of the worlds energy use and greenhouse gas emissions but is also one of the sectors that are best rigged to cut energy and emissions ... -
Ventilative cooling as a solution for highly insulated buildings in cold climate
Alonso, Maria Justo; Mathisen, Hans Martin; Collins, Rose (Peer reviewed; Journal article, 2015)One of the downsides of super insulated building envelopes is their facility to be overheated needing removal of excess heat. The removal of surplus heat is often done by mechanical cooling. However, energy consumption ... -
Ventilative cooling for schools and kindergartens
Øgård, Yngvar Grimsbo (Master thesis, 2014)As the building industry strives towards the goal of ZEB (zero emission/energy buildings), new and refurbished modern day buildings have to relate to ever increasing standards regarding energy efficiency and energy ...
