Abstract

Building energy simulation is an important supporting tool for green building design and building energy consumption assessment, At present, Building energy simulation software can't meet the needs of energy consumption analysis and cabinet level micro environment control design of prefabricated building. thermal physical model of prefabricated building is proposed in this paper, based on the physical model, the energy consumption calculation software of prefabricated cabin building(PCES) is developed. we can achieve building parameter setting, energy consumption simulation and building thermal process and energy consumption analysis by PCES.

Highlights

The background of PCES design and development of prefabricated compartment industrial building energy consumption simulation software mainly includes the following three aspects: 1) Prefabricated cabin buildings are faced with unprecedented opportunities for development: with the development of smart grid, as a center of power dispatching and control, intelligent substation will usher in a new wave of construction
In practical application, prefabricated building module exist in the power industry, such as container data center, communications industry, mobile base station are prefabricated building module category, the common features for precast monolithic construction, lightweight enclosure structure, heat rejection to heat equipment fever; the difference of power equipment the tank body is not equipped with a, so the energy density is different
In the prefabricated class of buildings widely used in the communications industry, the situation is not optimistic, the entire telecommunications industry's annual electricity consumption has more than 20 billion kwh [2], of which the base station power consumption accounted for 73%[3] of total electricity consumption

Summary

Introduction

The background of PCES design and development of prefabricated compartment industrial building energy consumption simulation software mainly includes the following three aspects: 1) Prefabricated cabin buildings are faced with unprecedented opportunities for development: with the development of smart grid, as a center of power dispatching and control, intelligent substation will usher in a new wave of construction. It is difficult to meet the needs of energy consumption analysis and cabinet level micro environment control design of prefabricated cabin buildings. With the rapid development of computer technology, a great deal of complex computing could be put into practice This short presentation of a number of building energy simulation software, including the United States' BLAST[5], DOE-2[6], Europe's ESP-r[4], China's DeST[7] and Japan's HASP, etc. The above research is to comfort people for the moderate target of environment control of civil construction type, and more to the building function zoning thermal environment as the research subject, the core operation simulation of cabinet level micro environment almost no parts of equipment

The foundation of building thermal physics model

Indoor net energy consumption
