A Simplified Method for Evaluation Model of Physical Performance of Traditional Building Composite Vertical Envelope

Abstract

The invention discloses a method for simplifying the physical performance evaluation model of a traditional building composite vertical enclosure structure, which comprises the following steps: (1) importing building facade graphic data, marking the materials used in each part of the facade through image recognition, and performing the following steps: Classify and mark; (2) carry out facade simplification, according to the classification standard of step (1), carry out sideline simplification and detail simplification to building facade; (3) calculate single facade each classification area and sum of area, and obtain Quantitative energy-saving data of window-to-wall ratio, effective daylighting area ratio, and effective ventilation area ratio; (4) Using the simplified sidelines and details of the facade, respectively establish a ventilation simulation calculation model in PHOENICS software, and establish a daylighting simulation in Ecotect software Computational model. The invention can scientifically quantify various physical properties of the traditional building envelope, and digitally protect the traditional building envelope.

Description

technical field [0001] The invention relates to the technical field of architectural design, in particular to a method for simplifying the physical performance evaluation model of a traditional building composite vertical enclosure structure. Background technique [0002] With the continuous improvement of people's requirements for the quality of life, energy-saving, comfortable and healthy green buildings have become the development direction of modern buildings. The envelope structure not only divides the space, but also serves as a medium for indoor and outdoor energy exchange. Its heat transfer and heat consumption account for more than 70% of the total energy consumption of the building, and it is an important link in the improvement of building performance. Among them, the improvement of the physical performance of the vertical envelope structure as the main envelope interface undoubtedly plays a key role in reducing building energy consumption and improving the comfor...

Problems solved by technology

However, although the relevant professional models that can be used for natural lighting, heat transfer and natural ventilation analysis are very rich, most of them are professional analysis software in non-architectural fields, and there are often various problems when used in traditional building physical performance analysis. For example, the parameter setting is complicated, the architectural form description is difficult, the intuitiveness is poor, etc.

An overly simplified model may cause the model to fail to meet the needs of the description of physical phenomena in the research, while the use of an overly complex model will greatly reduce the work efficiency, but the effect of improving the accuracy of the calculation results is not obvious
