Method for calculating architectural energy saving rate based on human body thermal adaptive model

Abstract

The invention discloses a method for calculating architectural energy saving rate based on a human body thermal adaptive model. The method comprises the following steps of: obtaining annual outdoor meteorological data of a building proposed site; calculating the mean natural room temperature of a building; drawing a thermal neutral temperature curve according to the thermal adaptive model; calculating a standard energy consumption; calculating an architectural energy consumption; calculating an architectural energy saving rate; establishing a standard model; calculating the energy saving rate of the standard model; judging the architectural energy saving rate; adjusting architectural parameters. According to the method, the shortcomings that the indoor comfortable temperature related to current architectural energy saving design standards in China is based on a PMV steady-state model and the energy saving rate of the building is not perfectly improved through the narrow comfortable area of the model according to the building design are overcome; meanwhile, the shortcoming that the number of energy saving goals achieved through the building design and the number of the energy saving goals achieved through equipment of one building cannot be accurately determined is overcome; the method is suitable for guiding the thermal performance design of the buildings and enclosure structures.

Description

technical field [0001] The invention relates to the field of building energy saving, in particular to a calculation method for building energy saving rate based on a human body thermal adaptation model. Background technique [0002] At present, China's current building energy-saving calculation method is based on building energy-saving design standards for different climate zones and different building types, such as "Design Standards for Energy Conservation of Residential Buildings in Severely Cold and Cold Regions" (JGJ26), "Design Standards for Energy Conservation of Residential Buildings in Hot Summer and Cold Winter Regions" "(JGJ134), "Design Standards for Energy Conservation of Residential Buildings in Hot Summer and Warm Winter Areas" (JGJ75) and "Design Standards for Energy Conservation of Public Buildings" (GB50189), each standard uses the energy saving rate as the building energy saving target. Building energy efficiency rate refers to the ratio of the annual ener...

Problems solved by technology

[0003] The indoor thermal environment standard based on the current building energy-saving calculation method in my country is the PMV model based on the results of artificial climate experiments. This energy-saving calculation method has certain limitations. The reasons are as follows: (1) The comfort temperature is based on the PMV steady-state model. The relatively narrow comfort zone of this model prevents the architectural design from improving the energy-saving rate of the building. The energy-saving control parameters of the two parts of the system are used to achieve the goal, and it is impossible to accurately determine how much of a building's energy-saving goal is achieved through architectural design

That is to say, in order to achieve the 65% energy-saving goal of a building, the architect may use equipment systems to achieve the goal. The result is a seemingly energy-saving building, but it is actually a high-energy building; The calculation of the energy saving rate is based on the benchmark building energy consumption. This benchmark energy consumption is only for the northern region of my country, without considering the energy consumption of buildings in other climate zones in my country at that time. The energy saving rate calculated on this basis is not very good. Measuring the energy efficiency of the building itself
