Analysis of energy signatures and planning of heating and domestic hot water energy use in buildings in Norway
Tereshchenko, Tymofii; Ivanko, Dmytro; Nord, Natasa; Sartori, Igor (Conference object; Journal article; Peer reviewed, 2019)Widespread introduction of low energy buildings (LEBs), passive houses, and zero emission buildings (ZEBs) are national target in Norway. In order to achieve better energy performance in these types of buildings and ... -
Analysis of monthly and daily profiles of DHW use in apartment blocks in Norway
Ivanko, Dmytro; Walnum, Harald Taxt; Sørensen, Åse Lekang; Nord, Natasa (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 ... -
Development and analysis of hourly DHW heat use profiles in nursing homes in Norway
Ivanko, Dmytro; Walnum, Harald Taxt; Nord, Natasa (Peer reviewed; Journal article, 2020)Representative profiles for domestic hot water (DHW) heat use are the main instruments for improve- ment in operation and design of DHW systems in buildings. To improve the existing method for DHW heat use profiles development ... -
DHW tank sizing considering dynamic energy prices
Nord, Natasa; Ding, Yuemin; Ivanko, Dmytro; Walnum, Harald Taxt (Peer reviewed; Journal article, 2021)Due to the rapid development of the building stock in Norway, the energy use in this segment is drastically increasing. Therefore, improving the energy performance of buildings becoming an urgent problem. Among technical ... -
Domestic hot water decomposition from measured total heat load in Norwegian buildings
Lien, Synne Krekling; Ivanko, Dmytro; Sartori, Igor (SINTEF Proceedings;5, Chapter; Conference object; Peer reviewed, 2020)In Nordic climates, the energy use in buildings is dominated by space heating (SH) and domestic hot water (DHW). Heat load measurements with hourly resolution from smart meters are now becoming the standard. However, in ... -
Energy consumption for domestic hot water use in Norwegian hotels and nursing homes
Walnum, Harald Taxt; Sørensen, Åse Lekang; Ludvigsen, Bjørn; Ivanko, Dmytro (Journal article; Peer reviewed, 2019)Domestic Hot Water (DHW) production constitutes a significant proportion of the energy demand of modern buildings, and as the building envelope is improved the share increases. This article discusses the results from a ... -
Identifying typical hourly DHW energy use profiles in a hotel in Norway by using statistical methods
Ivanko, Dmytro; Nord, Natasa; Sørensen, Åse Lekang; Plesser, Thale Sofie Wester; Walnum, Harald Taxt; Sartori, Igor (Journal article; Peer reviewed, 2019)The aim of this research is to improve the existing approaches of domestic hot water (DHW) energy use analysis in buildings. A comprehensive statistical analysis of hourly DHW energy use for a hotel in Oslo, Norway, was ... -
Prediction of DHW energy use in a hotel in Norway
Ivanko, Dmytro; Nord, Natasa; Sørensen, Åse Lekang; Sartori, Igor; Plesser, Thale Sofie Wester; Walnum, Harald Taxt (Journal article; Peer reviewed, 2019)Domestic hot water (DHW) systems are significant consumers of energy in buildings. This article is dedicated to hourly and daily DHW energy use modeling, with the aim of achieving energy savings in buildings. The methods ... -
Selecting the model and influencing variables for DHW heat use prediction in hotels in Norway
Ivanko, Dmytro; Sørensen, Åse Lekang; Nord, Natasa (Peer reviewed; Journal article, 2020)Domestic hot water heat use prediction modelling is an important instrument for increasing energy efficiency in many buildings. This article addressed hourly domestic hot water heat use prediction, using a Norwegian hotel ... -
Splitting measurements of the total heat demand in a hotel into domestic hot water and space heating heat use
Ivanko, Dmytro; Sørensen, Åse Lekang; Nord, Natasa (Peer reviewed; Journal article, 2020)To achieve more efficient energy use in buildings, space heating (SH) and domestic hot water (DHW) heat use should be analysed separately. Unfortunately, in many buildings, the heat meters measure the total heat use only, ...
