Assessment of heating and cooling demands of a glass greenhouse in Bucharest, Romania
Brækken, August; Sannan, Sigurd; Jerca, Ionut Ovidiu; Bädulescu, Liliana (Peer reviewed; Journal article, 2023)In southern parts of Europe, a balanced use of both heating and cooling is required to control the greenhouse temperatures throughout the year. Especially, with climate change and increasingly hot summers, the need for ... -
Flexibility through power-to-heat in local integrated energy systems with renewable electricity generation and seasonal thermal energy storage
Kauko, Hanne Laura Pauliina; Brækken, August; Askeland, Magnus (Peer reviewed; Journal article, 2024)In heating dominated regions, the flexibility obtained through coupling heating and power sectors is particularly beneficial for the integration of high shares of variable renewable energy sources. This study concerns the ... -

Nyhavna – et nullutslippsnabolag med systemsmart energiforsyning
Kauko, Hanne Laura Pauliina; Brækken, August; Askeland, Magnus (ZEN Report;64, Research report, 2024)Nyhavna er et område i Trondheim som per i dag hovedsakelig brukes til industrielle formål, men som skal utvikles til et attraktivt boligområde i de kommende tiårene. Ifølge kvalitetsprogrammet skal området ikke føre til ... -
Performance analysis of high temperature heat pumps and thermal energy storages for a dairy
Ahrens, Marcel Ulrich; Brækken, August; Foslie, Sverre Stefanussen; Moen, Ole Marius; Lovas, Kim Andre; Bantle, Michael; Hafner, Armin; Eikevik, Trygve Magne (Science et technique du froid;, Chapter; Peer reviewed, 2022)This paper analyses the performance of the integrated energy system of an existing dairy in Bergen, Norway. The investigated dairy has an innovative solution for the thermal process supply by using only heat pumps and ... -
Physio-chemical properties of two cherry tomato varieties in relation to the greenhouse environmental factors
Frangulea, Mihai; Bädulescu, Liliana; Jerca, Ionut Ovidiu; Dräghici, Elena Maria; Bantle, Michael; Sannan, Sigurd; Brækken, August; Cimpeanu, Sorin Mihai (Peer reviewed; Journal article, 2022)To prevail on the agricultural market, greenhouse grown cherry tomatoes need to meet certain quality standards. The quality can be assessed by determining several chemical and physical characteristics. The aim of the ...
