Description
Technical field
The invention belongs to the energy-saving building technology field, relate in particular to a kind of method of passing judgment on the building energy conservation assessment.
Background technology
Along with popularization and the use of building energy effect system, the meaning of energy effect system in building energy conservation is more and more important, and the building energy conservation sign is important ingredient in the energy effect system, and its core content is how the building efficiency to be carried out the assessment of justice.What extensively adopt in the building energy effect system at present is relatively to draw a score value as the energy consumption index foundation by history value.As shown in Figure 1, this assessment may further comprise the steps: obtain historical building power consumption values E' and current building energy consumption value E, utilize formula S=E/E' to calculate score value, and according to score value S building energy consumption is assessed, corresponding S value is energy-conservation less than 1, and corresponding S value is highly energy-consuming greater than 1.The method is only assessed current building energy consumption according to the building energy consumption history value, and this scheme is only applicable to carry out the building energy consumption assessment in the fixing situation of floor area of building A, flow of the people B, planning index C.Because A, B, three parameters of C may have greatly changed in a short time, thereby it is larger to make assessment out get score value S deviation.Cause the building energy consumption assessment inaccurate, unreasonable.
Summary of the invention
On the basis of the present invention's energy efficiency evaluating method deficiency in analyzing energy management system, to the existing building energy potential evaluation time, set up the key horizon of assessment energy consumption level by three basic efficiency factor index floor area of building A, flow of the people B, planning index C, use analytical hierarchy process to determine the weight system of three indexs, carry out check analysis by historical data again, and carry out the ranking score value and assess, height by evaluation grade carries out comprehensive evaluation to building at last, makes building energy consumption obtain effectively accurately data assessment.
A kind of building energy conservation appraisal procedure of proposition of the present invention mainly may further comprise the steps:
The first step according to the score value of building energy consumption density, personnel's energy consumption density and the planning index in current period, obtains the comprehensive scores E of the building in current period;
Second step according to the score value of building energy consumption density, personnel's energy consumption density and the planning index of period of history, obtains the comprehensive scores E' of the building of period of history;
In the 3rd step, relatively draw the building comprehensive scores according to comprehensive scores and the comprehensive scores in current period of period of history.Building comprehensive scores S computing formula: S=E/E';
The 4th step, according to building comprehensive scores assessment building energy consumption level, wherein comprehensive scores S is higher, building energy consumption is higher, S 〉=1.5 are defined as star power consumption state, and 1.2≤S＜1.5 are defined as two stars power consumption state, and 0.9≤S＜1.2 are defined as three-star power consumption state, 0.6≤S＜0.9 is defined as four-star power consumption state, S＜0.6 is defined as five-star power consumption state.

Embodiment
As shown in Figure 2, appraisal procedure provided by the invention may further comprise the steps, referring to Fig. 5:
The first step is weighted the score value of building energy consumption density, personnel's energy consumption density and the planning index in current period, obtains the comprehensive scores of the building in current period.
In the first step, calculate building energy consumption density JP, personnel's energy consumption density RP in current period, and planning index DP, wherein planning index refers to the realtime power of equipment and the ratio of rated power (referring to the ratio of realtime power sum and the rated power sum of all devices here), and obtain building energy consumption weight j, personnel's energy consumption weight r, planning index weight d, obtain the building comprehensive scores in current period according to formula E=JP*j%+RP*r%+DP*d%.Wherein:
Building energy consumption density JP=P/J, P are the building energy consumption in current period, and J is floor area of building, referring to Fig. 2;
Personnel's energy consumption density RP=P/R, R is the flow of the people R of the building in current period, referring to Fig. 4;
The planning index in current period
Wherein
The i platform equipment realtime power in current period,
The rated power of i platform equipment,
That i platform equipment is in the working time in current period, referring to Fig. 3;
When setting building energy consumption weight j, personnel's energy consumption weight r, planning index weight d, satisfy j+r+d=100, and the value of j, r and d can be decided according to architectural character.The floor area of building amplitude of variation of the type of for example handling official business building is very little, and flow of personnel is larger, and the planning index amplitude of variation is less, and then can set j is that 15, r is that 60, d is 25.The value of j, r and d is not that permanent set is constant, decides on architectural character.
Second step is weighted the score value of building energy consumption density, personnel's energy consumption density and the planning index of period of history, obtains the comprehensive scores of the building of period of history.
In second step, calculate building energy consumption density JP', the personnel's energy consumption density RP' of a certain period of history, and planning index DP', and obtain building energy consumption weight j', obtain personnel's energy consumption weight r' and planning index weight d', obtain the building comprehensive scores of this period of history according to formula E'=JP'*j'%+RP'*r'%+DP'*d', " current period " is time on year-on-year basis in above-mentioned period of history and the first step, for example be 2012-1-1 to 2012-8-15 current period, and the period of history can be 2011-1-1 to 2011-8-15 or 2010-1-1 to 2010-8-15 so.Wherein:
Building energy consumption density JP'=P'/J, P' are the building energy consumption of period of history, and J is floor area of building;
Personnel's energy consumption density RP'=P'/R', R' are the flow of the people R of the building of period of history;
The planning index of period of history
Wherein
J platform equipment at the realtime power of period of history,
The rated power of j platform equipment,
It is the working time of j platform equipment in the period of history, in this period of history, number of devices and device type and current period all might be inconsistent, and for example: the period of history is 5 equipment, may be 10 equipment current period, so use m indication equipment number of units in the period of history.
When choosing the weight of period of history, can choose the weighted value identical with current period.
The comprehensive scores E'=JP'*j%+RP'*r%+DP'*d% of the building of period of history then;
In the 3rd step, relatively draw the building comprehensive scores according to comprehensive scores and the comprehensive scores in current period of period of history.Building comprehensive scores S computing formula:
S=E/E'；
The 4th step is according to building comprehensive scores assessment building energy consumption level.
In general, building comprehensive scores S value will be floated in 1 left and right sides scope.If less than 1 then expression building is in power save mode; If greater than 1 then expression building is in the highly energy-consuming state.
Because S is a concrete numerical value, be unfavorable for that the layman understands, therefore the definition of star also can be set, we can the energy-conservation star of self-defined planning building according to different energy-saving indexs.
The star definition: I am defined as a star (highly energy-consuming state) to S 〉=1.5 usually, 1.2≤S＜1.5 are defined as two stars, 0.9≤S＜1.2 are defined as three-star, and 0.6≤S＜0.9 is defined as four-star, S＜0.6 is defined as five-star (high power save mode), totally five stars.
The present invention can solve in the energy management system the inaccurate problem of building energy efficiency evaluating method, effectively provides accurately data assessment foundation to the building energy conservation target.
