(LPD) basis《Standard for lighting design of buildings》(GB50034-2004) the LPD values of regulation, house are set as 7W/ ㎡, indoor
Primary illumination mode is selected as ceiling lamp illumination.
Simulation, which calculates, to carry out five individual simulated experiments according to the factor for the Dam Configuration Design for influencing building energy consumption, that is, divides
Simulation of energy consumption, the quantitative pass between each design parameter of independent analysis and energy consumption are not carried out using each factor as unique variable
System.
The method that the present invention mainly uses computer simulation carries out energy consumption research, embedded EnergyPlus simulation of energy consumption
Device can carry out simulation calculating to all energy consumptions of building in use, including heating energy consumption (Heat
Generation), air conditioning energy consumption (Chiller), lighting energy consumption (Lighting), system circulation water pump energy consumption (System
Pumps).It is 8760 hours annual to building since DesignBuilder softwares use EnergyPlus simulation of energy consumption engines
The simulation output of total energy consumption, energy consumption unit are kWh.And according to《Energy efficiency design of office buildings standard》In be used for evaluate building energy
The index of consumption is heat-consuming index, and unit uses W/ ㎡, i.e., what unit construction area consumed within the unit interval need to be adopted by interior
The heat of heating equipment supply.Therefore when carrying out energy consumption index evaluation, DesignBuilder should be simulated the data obtained and be converted into often
Square meter builds power consumption values hourly.
The total energy consumption built under different designs parameter and unit building energy consumption are obtained respectively, and not to single influence factor
Energy consumption level and fractional energy savings comparison are carried out with situation, the five big Dam Configuration Designs for influencing building energy conservation are obtained with Excel softwares
Quantitative relationship curve between factor and building energy consumption.
In conjunction with the quantitative relationship of building shape design parameter and energy consumption, the maximum energy-saving build of building is obtained, and can be herein
On the basis of, obtain the opposite energy-saving effect of design scheme, and then carry out the design of next step.
Above conclusion provides foundation and reference from Energy Angle for the initial design decision of architect, and should be with passive type
Based on the energy-saving design of space, facade form element, building enclosure in conjunction with office building construct and the energy saving of device systems is set
Meter excavates passive type energy-saving design potential, the final realization for realizing Energy Saving of Office Building target.
