On-site solar PV generation and use: Self-consumption andself-sufficiency

Building Simulation 2023年第10期16卷 1835-1849页

作者： Zheng Wang Mark B.Luther Peter Horan jane matthews Chunlu Liu School of Architecture and Built Environment Deakin UniversityGeelongAustralia

As energy storage systems are typically not installed with residential solar photovoltaic (PV) systems,any “excess” solar energy exceeding the house load remains unharvested or is exported to the *** paper introduces an approach towards a system design for improved PV self-consumptionand self-sufficiency. As a result, a polyvalent heat pump, offering heating, cooling and domestic hotwater, is considered alongside water storage tanks and batteries. Our method of system analysisbegins with annual hourly thermal loads for heating and cooling a typical Australian house inGeelong, Victoria. These hourly heating and cooling loads are determined using Transient SystemSimulation (TRNSYS) software. The house’s annual hourly electricity consumption is analysed usingsmart meter data downloaded from the power supplier and PV generation data measured with aPV system controller. The results reveal that the proposed system could increase PV self-consumptionand self-sufficiency to 41.96% and 86.34%, respectively, resulting in the annual imported energybeing reduced by about 74%. The paper also provides sensitivity analyses for the hot and coldstorage tank sizes, the coefficient of performance of the heat pump, solar PV and battery *** establishing the limits of thermal storage size, a significant impact on self-efficiency can berealised through battery storage. This study demonstrates the feasibility of using a polyvalent heatpump together with water storage tanks and, ultimately, batteries to increase PV self-consumptionand self-sufficiency. Future work will concentrate on determining a best-fit approach to systemsizing embedded within the TRNSYS simulation tool.

Model server enabled management of collaborative changes in building information models

Frontiers of Engineering Management 2018年第3期5卷 298-306页

作者： Muhammad Tariq SHAFIQ jane matthews Steve LOCKLEY Peter E.D.LOVE Department of Architectural Engineering University of the United Arab EmiratesUAE Department of Construction Management Curtin University Department of Architecture and Built Environment Northumbria University Department of Civil Engineering Curtin University

The issues and challenges involved in controlling the collaborative changes in a Building Information Modeling(BIM) data repository, in a multi-model collaboration environment, are discussed. It is suggested that managing iterative changes in BIMs is a database problem, exacerbated by the long transaction times needed to support collaborative design progression. This is yet to be resolved in the construction industry and better solutions are needed to support the underlying workflows and computing operations for seamless collaboration on BIMs. With this in mind, this paper proposes the use of the structural and semantic characteristics of BIM objects as a mechanism for tracking changes across co-developed solutions. The creation of object signatures, using hash codes derived from their characteristics, provides a potential mechanism for object comparison and effective change recognition and management.

1. Introduction While the applications of computer visions are varied in construction, research has tended to focus on measuring the accuracy of object detectors such as faster region-based-convolution neural networks (Faster R-CNN) and single shot detector algorithms (SDD)[1]. Limited, if any, attention has focused on determining the benefits of such technology in construction beyond the claims that it can help detect problems quickly and accurately. Reinforcing this point are the numerous review papers that have frequented the literature [2,3].

Science communication in China: a critical component of the global science powerhouse

引用

National Science Review 2020年第4期7卷 824-829页

作者： jane Qiu Writes for NSR from Beijing

China has attached a great significance to bringing science to the public—known as kepu(, ‘science popularization’) or kexue chuanbo(, ‘science dissemination’)—in recent years, partly in response to its unprecedented push for innovation in science and technology. In 2018, it spent 16 billion yuan(US$2.3 billion) on such endeavours, nearly 80% of which was government funding, according to a survey conducted by the Ministry of Science and Technology. With one science-education venue for every million people, approximately 76 million visits
