Thermal mass and the effects on heating and cooling demands – an experimental study of an exposed concrete floor
(Peer reviewed; Conference object; Journal article, 2020)The increase of thermal mass in buildings is discussed as a useful measure for reducing the energy demand for heating and cooling while contributing to improve the internal comfort. Several studies confirmed its positive ... -
Impact of Typical Faults Occurring in Demand-controlled Ventilation on Energy and Indoor Environment in a Nordic Climate
(Peer reviewed; Conference object; Journal article, 2020)This study evaluates typical faults occurring in demand-controlled ventilation (DCV) system and the impact on three output results: energy use, thermal comfort, and indoor air quality. The methodologies used in this study ... -
Risk-based Optimization of Sensor Distribution in Roof Constructions – A Conceptual Study
(Peer reviewed; Conference object; Journal article, 2020)The objective of placing moisture sensors in roof constructions is to warn about leakage events, and thus avoid undesirable consequences. However, considering that placing an additional sensor is directly related to ... -
Experiences with external drainage systems from compact roofs in Norwegian climates
(Peer reviewed; Conference object; Journal article, 2020)To reduce loads on urban drainage systems and facilitate local infiltration of stormwater, it is desired to lead runoff water from roofs through external drains and into the local soil. However, in cold climates, situations ... -
Acceptable air velocities using demand-controlled ventilation for individual cooling
(Peer reviewed; Conference object; Journal article, 2020)One of the main challenges in highly insulated buildings is the increasing share of energy demand for cooling. New solutions for low energy cooling are needed. Individual cooling by demand-controlled ventilation and use ... -
Analysis of monthly and daily profiles of DHW use in apartment blocks in Norway
(Peer reviewed; Conference object; Journal article, 2020)Profiles of domestic hot water (DHW) use give valuable information for achieving energy saving in buildings. In this article, analysis of monthly and hourly profiles in apartment blocks in Norway was performed. The aim was ... -
Prevailing Approaches and Practices of Citizen Participation in Smart City Projects: Lessons from Trondheim, Norway
