Since at such early stages, numerous design variables are still undetermined (e.g. window type, insulations, etc.) the scenarios to be simulated through BPS will be vast and will require extensive time and computational power. Previous studies have tested the sensitivity of a building’s energy consumption during its operation, to design parameters. Most of those studies, however, have used a single case study in their analysis. Thus, the objective of this paper is to evaluate the dependency of results of such sensitivity analyses, on the case study being used. To accomplish that, a hybrid method combining one-parameter-at-a-time (OAT) and global samplings was used. Within the cold climate scope of Québec, Canada, multiple buildings were used to investigate the sensitivity of energy and economy performance to design parameters (architectural, electrical, and mechanical systems); as well as the sensitivity of parameters’ impact on building models. Results indicate that architectural and electrical parameters are sensitive to the model. To expand on the understanding of the root cause of this sensitive behaviour, hypotheses were developed and evaluated through global sampling.","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"16 1","pages":"466 - 488"},"PeriodicalIF":2.0,"publicationDate":"2021-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45341560","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 thermo -physical and microstructural characteristics of sisal/nonwoven wool were determined experimentally. Also, the tensile strength of sisal/nonwoven wool was systematically evaluated. The thermal conductivity coefficient of the fabricated sample is 0.038 W/(m. K) and is comparable and very satisfactory compared to traditional materials. This work results show high potential for the applicability of nonwoven designs from sisal fibre in the building. Exceptional thermal performance, low density, fire resistance, and air permeability factors have confirmed that this is a promising product for the thermal insulation market. The thermal performance of the developed material, integrated into an exterior wall and exposed to the climatic conditions of the Mediterranean climate, was performed. It was found that the wall made with the developed nonwoven designed from sisal fibre material provides a 78% reduction in annual cooling energy needs and a 76% reduction in annual heating needs. The specific cost of the developed insulation materials is studied, and the results show that the designed insulation can be a competitive solution.","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"16 1","pages":"489 - 513"},"PeriodicalIF":2.0,"publicationDate":"2021-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48803845","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}

This paper aims to broaden the current knowledge of the relation between the exposed surface area of a macro-encapsulated PCM panel and the heat transfer with the environment. For this study, coconut oil was considered as PCM encapsulated in a thin plastic container, represents an aesthetic PCM panel attached to the ceiling. The results showed that an increase of 50% in the exposed surface area to volume ratio could lead to a 20% reduction of the time required to completely melt the PCM. Results also showed that the convective heat transfer coefficient is proportional to the exposed area to volume ratio, and for that an equivalent heat transfer coefficient is proposed to be used in building simulation tools when dealing with non-slab geometry.","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"16 1","pages":"445 - 465"},"PeriodicalIF":2.0,"publicationDate":"2021-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41809007","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 approaches used for the creation of future weather climate and building renovation scenarios, as well as building energy modeling at different scales, are evaluated.

The decrease/increase rates varied significantly depending on the climate and case study building(s) considered, with buildings and building energy systems located in extreme climates being more sensitive to such changes. The main uncertainty of the predicted increase/decrease rates can be assigned to climate models and forecasted weather data. Nonetheless, such forecast and risk assessment are necessary for sustainable development of urban environment and associated energy systems. Further development of dynamic large-scale building energy simulation tools is required, along with the development of large-scale building renovation measures and strategies that take into account additional aspects (such as economic and societal).

In this paper, we study to which extent hydraulic imbalance affects the thermal energy demand of buildings. Furthermore, key variables and interactions that influence the thermal performance of buildings are identified. In the first part, a dataset, including building features, boiler capacity and energy consumption of 49 multifamily buildings in Geneva (Switzerland), is analysed. Applying regularization regression, we find that higher variation in indoor temperature leads to larger energy consumption. Buildings constructed before 1980, having large boiler capacity and large heated floor area, are more likely to be hydraulically imbalanced and to consume more energy, indicating higher energy saving potential from hydraulic balancing. The second part consists of a case study of four multifamily buildings in Geneva where hydraulic balancing was implemented. We monitor data associated with temperature levels and energy consumption and find that hydraulic balancing significantly reduces the temperature spread avoiding overheating. The yearly energy savings by hydraulic balancing at an outdoor temperature of 0°C are estimated at 9% in Geneva.","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"16 1","pages":"427 - 444"},"PeriodicalIF":2.0,"publicationDate":"2021-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17512549.2021.1873184","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47326562","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}

However, these systems rely on dynamic factors that are stochastic and difficult to predict, such as the load consumption and electricity prices. Therefore, constructing an efficient control system for residential buildings requires an accurate prediction process of the associated parameters. This paper proposes an integrated predictive control system that consists of both predictive model and Demand Response (DR) scheme to predict and control the daily electricity usage in the residential sector. First, a Long Short-Term Memory-based (LSTM) optimized predictive model is implemented for predicting both the hourly load consumption and electricity price for a typical smart home. Then, the predicted data are transmitted to a DR fuzzy logic-based controller that can optimally schedule the home appliances usage. In comparison with the state-of-the-art prediction techniques for the residential load consumption and electricity price, the proposed LSTM predictive model outperforms Linear Regression (LR), Decision Tree (DT), Support Vector Regression (SVR), and Ensembled Boosted Trees (EBT). Moreover, the proposed DR-FIS controller has shown good results in terms of reducing the electricity cost by selecting the optimal time schedule.","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"16 1","pages":"262 - 280"},"PeriodicalIF":2.0,"publicationDate":"2021-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17512549.2021.1873183","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41621689","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 methodology consists of two multivariate statistical analysis methods, namely Principal Component Analysis (PCA) followed by cluster analysis. The methods were applied on monitored gas consumption data of five dwellings in Italy. Findings support literature indicating that people heat their homes in different ways. It was found that households do not always follow a different heating schedule on weekends, have very different temperature preferences and operate the heating system at different hours during the day. In fact, some households may change heating practices over the heating season. The highlight of the proposed methodology is the insightful and simple way that PCA can extract succinct information about the heating behaviour of the user.","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"16 1","pages":"322 - 346"},"PeriodicalIF":2.0,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17512549.2020.1863858","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45473846","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}
