| There are various psychological factors that affect the behavior of water users.This paper analyzes the psychology of the people who go in and out of public buildings.According to the theory of planned behavior,in this theory,attitude,criteria and behavior control have an impact on the actual intention,and ultimately affect the actual behavior.By setting the corresponding questions,online and offline questionnaires are put to obtain data.A total of 1011 online questionnaires and 78 offline questionnaires were collected.Through the construction of TPB model for 1011 online questionnaires,one-way ANOVA and nonparametric analysis were used for offline questionnaires.The final results show that water-saving behavior of public buildings is affected by social norms and water-saving attitude,while the expected results have no significant impact on water-saving behavior.Among them,water-saving attitude has a greater impact on water-saving behavior.Therefore,we can start from the influencing factors of water-saving attitude,carry out targeted intervention and publicity,improve the attitude of water-saving,and save water with a more active attitude and behavior,so as to reduce the use of water resources.In order to explore the actual water use situation of public buildings and whether there are differences before and after psychological intervention,this experiment through the selection of appropriate public buildings,the installation of high-precision remote water meter,the installation of water meter for each appliance in the selected toilet,the data of water meter is connected with each water appliance.The actual water consumption in the building was collected for one month,and the actual water consumption data of each user every hour and every minute were collected.The total water consumption of each dormitory,teaching building and office building on weekdays and non weekdays,as well as the difference of water consumption in each period of 24 hours were counted.Targeted intervention was carried out according to the conclusions of TPB model,The changes of actual water consumption and maximum instantaneous flow of each toilet before and after the intervention were obtained.The results show that the purpose of water saving can be achieved through targeted intervention.At the same time,according to the experimental results,the current design second flow formula is modified,and psychological factors are introduced to improve the calculation accuracy.In order to make the design data more accurate,the design formula of design second flow in China is improved according to the results of psychological analysis.Because the current design second flow formula in China only considers the building categories,the design second flow formula and the parameters are the same in the same class of buildings.One of the reasons for the low accuracy of the current formula is that the various factors affecting the actual water use are not fully considered.The current formula has extensive classification and does not consider the possible impact of the actual water consumption behavior of the actual water users on the pipe network.This paper selects the dormitory,teaching building and office building to install the remote water meter with the accuracy of 1min after the investigation in a university in Harbin,The actual water consumption data of the three types of building entrants and exits were collected,and questionnaires were sent to the entrants and exits at the same time.The questionnaire data were processed according to the model results obtained in the previous paper.Based on the analysis of the water meter data and the psychological consciousness score of the people in and out,the psychological parameters are introduced to further improve the design second flow formula,so that the design results are more accurate and reasonable,which can not only meet the actual requirements,but also cause the waste of resources. |
