Data centres (DCs) are large electricity consumers, estimated to account for around 1% of worldwide electricity usage. They release excess heat (EH) during the operation, which can be recovered in district heating (DH) networks. DCs are expected to satisfy the rising demand for digital services. The electricity usage for cooling and available EH from the operation of DCs depends on the air temperature that changes with geographical location. The changes are not uniform and global warming pathways will influence them. Here lays the contribution of the present article. We use an existing thermodynamic model of a hyper-scale DC for different locations in Ukraine to analyse the electricity usage for cooling and EH availability for two climate scenarios (RCP2.6 and RCP 4.5) in 2010–2050. The results show that the electricity consumption for cooling and available EH can vary greatly within Ukraine. The electricity consumption for cooling is over two times higher in the hottest compared to the coldest location in the country, while the emitted EH is around 80% higher on average. The global climate pathway has a minor influence — the electricity use for cooling and EH availability are 4% higher in RCP4.5 than in RCP2.6. Finally, one hyper-scale DC of 150 MW could cover the demand for space heating and domestic hot water for roughly 100 thousand people. This assessment is an important input to consider when developing plans to rebuild Ukraine.

Hundslund prioryThe history of its medieval buildingsThe Benedictine priory of Hundslund is situated in Vendsyssel, northern Jutland. It flourished from its establishment in around 1200 until the Reformation, after which it became transformed into a manor house, Dronninglund Slot. This transformation secured parts of the medieval complex, which are consequently preserved to the present day (figs. 1-4).The medieval complex consisted of a church and several buildings constructed at different times. The oldest part of the complex is the brick church, constructed around 1200 in a distinct Romanesque style similar to the nearby diocese church at Børglum and a small group of local parish churches. Some monastic buildings must have existed in conjunction with the church, but these have left almost no trace in the archaeological record (figs. 5-9).A building boom occurred in the latter part of the 15th century, and the church was subject to several building projects. The walls were raised and the church was vaulted, a tower was built on the west side of the nave and a large monastic wing was constructed. After a short break, rebuilding resumed in the early 16th century, when two transepts were added to the church as well as a porch, and a new west wing of monastic buildings was constructed. In addition to the dateable construction works, a major canal was constructed at the priory in the late medieval period, as well as some smaller buildings on the priory area (figs. 10-20).The priory church had a dual function, serving both the priory’s nuns and the local parish. This meant that the church and the monastic complex had to have a layout which secured the integrity of the monastic clause. Especially during the later Middle Ages, when there was a building boom, this may have been difficult to ensure, as the natural topography also imposed some limits with respect to where the monastic buildings could be constructed. This resulted in a somewhat unique structure, whereby the mo, Hundslund prioryThe history of its medieval buildingsThe Benedictine priory of Hundslund is situated in Vendsyssel, northern Jutland.
