Description
Technical field
The present invention relates to the calculation method of the nearly zero energy consumption house operation energy consumption of cold district, especially a kind of nearly zero energy consumption is lived
Residence Quasi dynamic Calculation Method of Energy Consumption, optimum design method.
Background technique
In existing building energy conservation, energy-saving design in construction is completed jointly by Architecture Speciality and heating and ventilating discipline, wherein building
The combination for learning profession responsible passive type power-saving technology and architectural scheme design is built, with emphasis on architectural scheme design, heating and ventilating discipline is negative
The combination for blaming active power-saving technology and existing building, with emphasis on energy saving calculation.The existing building energy consumption calculation method master in China
There are two major classes: static calculation method (heat-consuming index calculating etc.), Dynamic calculation method (EnergyPlus, DeST simulation
Deng), wherein static calculation parameter is complicated and accuracy is poor, and dynamic computing operation is complicated and low efficiency, both methods are all inconvenient
It is used in architect in the schematic design phase.
By the double action of specialty background and specialization, building scheme optimization design and building energy conservation calculating isolate into two
A stage: " first designing " stage of building scheme and " rear verifying " stage of building energy conservation calculating.Architect is for energy consumption calculation
It is unknown make it in architectural scheme design, blindly carry out " close rule design " referring to national energy-saving standard stipulating index.It is this
Design method and design pattern have three:
(1) design cycle for " first designing and verifying afterwards " causes the missing of scheme optimization design link, causes building scheme simultaneously
The scheme of non-optimal has carried out setting for " design-energy saving calculation-feedback redesign " although there is architect to recognize this problem
Process and method are counted, but is limited by Calculation Method of Energy Consumption, can only be carried out for several schemes than choosing, and can not effectively be obtained
To most energy-efficient design scheme.
(2) " closing rule to design " method causes architect to think, more energy saving, the south orientation window-wall ratio of the outer smaller building of heat transfer coefficient of window
Building energy consumption will be will lead to beyond energy saving igniter prescribed limits to increase, and it is true really not so.Applicants have found that passing
The corresponding building energy consumption of the small exterior window of hot coefficient may be higher, when south orientation window-wall ratio takes 0.6-0.8 (remote superstate standard), building
Energy consumption is minimum, and reason is that the promotion with exterior window thermal insulation property, influence of the solar gain to building energy consumption are likely larger than
Heat loss through conduction increases south orientation window-wall ratio and is beneficial to energy conservation instead.It can be seen that " closing rule design " method causes conceptual design to miss
Area.
(3) however as the development of nearly zero energy consumption building, if cannot be carried out in the building scheme stage to design parameter excellent
Change matching, which kind of active technology no matter the later period take all can not achieve the target of building side " energy demand minimum ".
