Climate is affected by spatial and temporal differences related to climate change and urban heat island effects, but the weather files used in building performance simulations (BPS) often remain unchanged and may represent weather observations generated from inadequate space and time for their application. This study investigated Swedish weather data using statistical methods and analysed i) the local differences related to rural and urban microclimates and ii) the country-wide differences linked to climate change; by comparing recent observation data to the respective EnergyPlus Weather (EPW) files. The findings reveal that there are significant differences between rural and urban temperature means, and that outdated model years of weather data files make them unsuitable for BPS. The impact of using an inadequate weather file based on changes in recent climate in Sweden can lead to an overestimation of heating demand by 6.5 % on average, while the impact is higher for warmer climates – up to 12 %. The combined impact including climate change and urban heat island effects can lead to a heating energy overestimation by 12 % to 19 %, based on the Stockholm example. On the other hand, it was found that although the global radiation means saw a slightly increasing trend, its impact on the BPS remains inconclusive. The study highlights the importance of selection of adequate weather data for BPS keeping in mind the spatial and temporal influencing factors.","PeriodicalId":448024,"journal":{"name":"Proceedings of the ISES Solar World Congress 2021","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115001975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A specified architecture combining a Return/Supply connection, a set of valves, a feed-in pump and a primary side connection of the solar field led to the conception and fabrication of a bidirectional substation prototype. The latter is tested in a hardware-in-the-loop configuration regarding the consumer and solar field sides while the DHN side of the substation prototype is connected to a real DHN. A 12-days sequence, representative of typical days, with varying solar irradiation, DHN thermo-hydraulic conditions and consumer demands is performed with the prototype. A set of indicators showed i) an inappropriate behavior of the controller during the coldest days, ii) various improvements of the solar fraction during the hottest days (with up to 52% of total solar fraction) and iii) rather good performances of the controller (about 90% effectiveness). The analysis was completed by the observation of detailed dynamic result for one day. Different operating regimes (full DHN consumption, solar self-consumption complemented by the DHN, solar self-consumption and feed-in) could be observed during a single day highlighting the modularity of the BSST to switch automatically (by hydraulic balancing) from one mode to the other.","PeriodicalId":448024,"journal":{"name":"Proceedings of the ISES Solar World Congress 2021","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131825948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
