本文介绍了整体式低碳建筑设计的方法,同时概述了计算机模拟技术和建筑物理工程师在实现建筑低碳节能设计中的重要作用。文章结合当前瑞士节能建筑实例,进一步阐述了计算机模拟技术如何帮助建筑师优化设计方案以实现低碳节能,同时创造出舒适健康的人居环境。计算机模拟技术可以准确预测建筑设计方案的性能或量化不同设计方案的性能以提供最合理的方案,其主要功能包括预测室内空气温度、表面积辐射温度,计算室内热量、制冷采暖负荷、机械通风和自然通风情况,以及室内外气流分布状况。
This article presents a holistic approach to low-carbon building design and outlines the important role of computer simulation and building physics engineers in achieving low-carbon energy-efficient building design. Combined with the current examples of energy-efficient buildings in Switzerland, the article further elaborates how computer simulation technology can help architects to optimize the design scheme to achieve low-carbon energy saving while creating a comfortable and healthy living environment. Computer simulation technology can accurately predict the performance of the architectural design or quantify the performance of different design solutions to provide the most reasonable solution. Its main functions include forecasting indoor air temperature, surface area radiation temperature, calculating indoor heat, cooling and heating load, mechanical ventilation and natural Ventilation, as well as indoor and outdoor airflow distribution.
