Design And Implementation Of Thermal Calculation And Analysis System For Building Windows Doors And Curtain Walls

Buildings are the space in which human beings exist and work. Doors and windows and curtain wall are important parts of the architecture and they are not only the communication channels between mankind and nature, but important components to achieve building functions. Windows and doors and curtain walls, as the envelope of buildings, perform poorly in terms of thermal insulation and which are the central key of building energy conservation. It is of great significance to develop systematic and stable construction energy-saving technical requirements and evaluation methods, and on the basis of which to research and develop corresponding software products in order to meet the requirements of building energy efficiency.This paper expands discussion on the regards of design and implementation process for thermal calculation and analysis system of building curtain walls and windows and doors, and elaborates general concept, structural system, main functions and implementation methods in the round. The system is designed for developing software system of building windows and curtain wall systems, its main function is to scientifically calculate thermal performance indicators of construction windows, doors an curtain walls and analysis its key factors and links infecting thermal performance, reveal principles and methods of energy conservation so as to find specific and effective solutions to improve thermal performance.The significance of this subject study are as follows:①conducive to the standardization of thermal calculation and analysis process for windows and doors and curtain walls system;②beneficial to improve design efficiency and reduce costs;③beneficial to enhance market competition capability;④help to improve building energy efficiency and environmental comfort;⑤fill the gap of thermal calculation and analysis system for domestic windows and doors and curtain wall system. The main contents of this paper focus on the design and implementation of key technologies of thermal calculation and analysis system of building curtain walls and windows and doors, including the following aspects:①Firstly, extract actual demands of software system and then determine main contents and system structure, according to the analysis on the status of similar domestic and foreign software and thermal calculation for construction windows and doors and curtain walls.②study heat transmission theory and characteristics of building door and window and curtain wall system, and analyze relative domestic and foreign technical standards, specifications and documents, set the enhancement of existing softwares performance as the goal and determine a more functional software requirements.③Select and identify the software development platform. Mainly to determine the software development tools, database systems and encryption methods and strategies.④establish the main modules of the software system, including the following parts:thermal performance index calculation, thermal performance analysis, database creation and the calculation and analysis on results output.The main innovations in this paper are as followes:①the use of the views and methods of systematic engineering.②put up with such important thoughts that energy-saving design of building curtain walls and windows and doors are the key of energy conservation.③propose systematic solutions from industry experts on the development of thermal performance of building curtain walls and windows and doors.④thermal calculation based on database technology.⑤thermal analysis techniques based on database.⑥the research and implementation on the automatic generation methods of thermal calculation and analysis report...
