基于BIM技术的光伏建筑一体化设计与分析

Design and Analysis of Photovoltaic Integrated Building Based on BIM Technology

目前国家大力提倡生态文明建设,光伏建筑是绿色建筑的重要内容,有利于促进节能减排,推动行业健康发展。以广州某住宅为例,基于BIM技术探讨光伏建筑一体化的设计与能耗分析。使用光伏系统设计软件PVsyst确定光伏组件及逆变器的选型及安装等关键参数,并模拟了光伏发电量。利用eQUEST软件建立了该住宅的信息模型,从围护结构、空调能效、光伏发电三个方面进行建筑能耗分析,给出能耗优化建议。分析结果表明光伏建筑能实现能源自给自足,BIM技术能快速推动绿色节能建筑的发展。

Nowadays,the government vigorously advocates the construction of ecological civilization domestically.Photovoltaic buildings play an important role in green buildings,which is beneficial to energy saving and healthy development of the construction industry.The paper takes a residential building in Guangzhou as an example and discusses the design and analysis of building integrated photovoltaics based on BIM technology.PVsyst,PV system design software,is utilized to determine the selection of PV modules,inverters and key parameters of installation,meanwhile,simulate the photovoltaic power generation.The eQUEST software is applied to establish the building information model,analyze the energy from the aspects of building envelope,energy efficiency of air conditioner and photovoltaic power generation,obtaining optimization suggestions.The results show that PV buildings can achieve self-sufficiency in energy,BIM technology can foster the rapid development of green energy-saving construction.
