This was performed for a single house in the cold-maritime climate of Bariloche (13,000 kWh/y), which could be fully satisfied by using ten collectors on 70°-inclined roof and 4.6 m3 tank, costing €12,900. This cost is noticeably lower than for previous large projects in cold-continental climates, what is supported by four key factors: (1) solar resource and heating demand in maritime climates are more distributed than in continental climates; (2) small aboveground tanks can get noticeably higher efficiencies and lower costs that huge underground tanks; (3) vacuum-tube collectors get higher performances than flat collectors during winters; (4) high winter solar yield is achieved by installing collectors on high tilt angles (or half on low-inclined roofs and half on walls). These four factors will be discussed by solar-thermal and cost analyses, by comparing the system performance for climatic conditions of Bariloche and Okotoks.","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"15 1","pages":"199 - 222"},"PeriodicalIF":2.0,"publicationDate":"2019-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17512549.2019.1688186","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45514857","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}

The system takes advantage of the variable optical properties of a thermochromic mortar coating on the façade to optimize thermal behaviour. The mortar is based on the addition of organic thermochromic pigments to the cementitious matrix and is characterized by a high solar reflectance for temperatures higher than a nominal colour change value (Tc) and a low solar reflectance for lower temperatures. Materials potentially useful for this innovative system were analysed in this work. As prepared thermochromic mortar specimens, mortar specimens coated with different UV protecting products and mortar specimens covered by filter glasses with different optical responses were exposed to controlled outdoor environmental conditions during several days. Surface and environmental temperatures were monitored during the experiment. Moreover, reflectance spectra of the samples were recorded every day early in the morning, when the environmental temperature is significantly lower than Tc, and in the afternoon, when it is significantly higher than this value. Most suitable materials for the intended application were defined from an analysis of the optical and thermal properties of these specimens and their durability.","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"15 1","pages":"146 - 160"},"PeriodicalIF":2.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17512549.2019.1684364","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43447303","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}

They are in urgent need to be refurbished to reduce their energy consumption. The standard solution for the rehabilitation of facades is to incorporate thermal insulation materials to reduce heat transmission. This work proposes an extension of the conventional approach: the installation of Trombe walls on sunny facades incorporating an outer layer of thermochromic mortar, the thermochromic Trombe wall (TTW). This improves the energy performance of the existing buildings by enhancing their solar gains. This paper describes the design and configuration of the new TTW system. While traditional solutions can be evaluated with a simple heat transfer equation, a complex energy model is needed to evaluate TTW. Energy simulation is used to determine parameters that influence thermal performance. Thermochromic mortar transition temperature is designed to achieve maximum efficiency. The results obtained from the parametric study were used to determine the aspects of the construction of the first prototype on a laboratory test cell. The information obtained from the experiment will be used for the calibration of the energy model that will establish the potential for the incorporation of the TTW to the existing buildings.","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"15 1","pages":"161 - 178"},"PeriodicalIF":2.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17512549.2019.1684365","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45866118","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}

Current PV cell temperature models mainly fail to provide accurate predictions in complex arrangement of BIPVs under various climatic conditions. To address this limitation, this paper proposes a new regression model for prediction of the BIPV cell temperature in various climates and design conditions, including the effects of relative PV position to the roof edge, solar radiation intensity, wind speed, and wind direction. To represent the large number of possible climatic and design scenarios, the advanced technique of Latin Hypercube Sampling was firstly utilized to reduce the number of investigated scenarios from 13,338 to 374. Then, a high-resolution validated full-scale 3-dimensional Computational Fluid Dynamics (CFD) microclimate model was developed for modelling of BIPV’s cell temperature, and then was applied to model all the reduced scenarios. A nonlinear multivariable regression model was afterward fit to this population of 374 sets of CFD simulations. Eventually, the developed regression model was evaluated with new sets of unused climatic and design data when a high agreement with a mean discrepancy of 3% between the predicted and simulated BIPV cell temperatures was observed.","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"14 1","pages":"527 - 549"},"PeriodicalIF":2.0,"publicationDate":"2019-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17512549.2019.1654917","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48082267","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}

Subsequently, for the four most densely cities, the climate change during the past 60 years (1959–2018) has been investigated. Results show that CDD values for all cities have increased gradually in the same period, while HDD values have decreased. According to linear interpolation, average daily CDD 24°C in the year 2025 for Tehran is estimated as 1.903 (694.595 yearly).

It is also worth mentioning that the precipitation and Humidity have an inverse relation with PCD.

This paper focused in the analysis of different inputs accuracy on the outputs of building energy simulation (BES) models, and its influence on thermal comfort and on the evaluation of retrofit solutions, concerning a Portuguese household. The methodology considered the comparison of different BES models considering three accuracy inputs levels. The first model considers default values from legislation and standards, the second considers detailed information from audit visits, and the third model considers the inputs defined after a calibration process using sensitivity analysis and optimization techniques. Furthermore, a retrofit analysis was performed by considering the multi-objective optimization of a surrogate model. From the calibration process, it was concluded that the thermal discomfort evaluation differs with the inputs’ accuracy. Moreover, the optimization suggests that the inputs’ accuracy also affects the optimal retrofit solutions. This approach helped to understand the influence of the inputs’ accuracy levels and the advantages of considering surrogate models to study residential retrofit.","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"15 1","pages":"630 - 661"},"PeriodicalIF":2.0,"publicationDate":"2019-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17512549.2019.1654916","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45346916","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}

The participants were asked to select their desired room lighting setting at 9am, 1pm and 5pm. The results indicate that the choices were dependent on the room conditions. The time-of-day influenced blind use choices in both orientations, however, it was a significant factor influencing lighting choices in the south facing office. In addition, participants’ choices resulted in less energy consumption than the baseline settings in EnergyPlus, since the maximum lighting option was rarely used.
