| It is of great significance to research hospital outpatient public space for it has huge outpatien amount as well as undeniable importance for users’ comfort and hospital image.Energy conservation and medical comfort improvement are two important directions of hospital research.However,there is a certain contradiction between improving medical comfort and reducing energy consumption in outpatient public space,which is largely due to insufficient attention to medical crowd and their behavior.With the transformation of green hospital building technology,the trend of energy-saving research has gradually changed from the original research on HVAC equipment to the research based on investigation and analysis of people’ behavior.Nevertheless,due to the great complexity,particularity and investigation difficulty of hospital users’ behavior,the amount of relevant research in hospital buildings,especially in outpatient public space is still of small scale.Based on the above analysis,this thesis is committed to improving the quality of hospital environment by exploring the relationship between people’s behavior and environment;At the same time,hospital energy conservation is taking into account so as to promote the development of cross fields of architecture,architectural physics,HVAC and other majors while based on the origin of architecture,This paper chooses the large general hospital in hot summer and cold winter area as the research object.Taking evidence-based design as the core theory,this paper uses a variety of research methods to conduct multi-directional and in-depth investigation on the hospital outpatient public space.The research analyzes and summarizes the characteristics and problems of outpatient public space from multiple levels,and puts forward corresponding design suggestions and strategies.The main research contents are as follows: 1.The current situation,characteristics and problems of thermal environment and thermal comfort in different spaces at different times were analyzed and summarized by investigation with measuring instrument and questionnaire;2.With the investigated behavior characteristics of medical crowd and medical staff in outpatient public space Using video recording,behavior tracking,inductive statistics etc.,this paper summarize the corresponding space problems of outpatient public space,and put forward some optimization suggestions accordingly;3.Through case analysis,this paper summarizes the designing methods of excellent energy-saving hospitals and the designing status and problems of outpatient public space of typical general hospitals in China.Then it puts forward the energy-saving strateies of outpatient public space suitable for China;4.The thesis proposed the demand-driven ventilation strategy based on the behavior of medical crowd and then deduce its control steps and simulate it.Through comparative analysis,its effectiveness of improving thermal comfort and reducing energy consumption is verified.The dissertation brings about conclusions below: 1.There are differences in different seasons and different space types of thermal environment and thermal comfort in outpatient public space.For seasons,the thermal comfort is found generally poor in autumn and winter.In terms of space types,the thermal comfort of public space of one-floor height is related to area and the floor;and the thermal environment and thermal comfort of public space of multi-floor height depends on the area and the total height.2.The behavioral characteristics of of medical crowd in outpatient public space include uneven distribution in time and space,lengthy and complex medical streamline,and that of medical staff is mainly presented as staggered peak duty.Accordingly,there are problems of spatial design such as spatial redundancy,spatial homogenization and imbalance of spatial services.Therefore,this paper puts forward some design suggestions as intensive design,optimizing the organization of functional space and optimizing the scheduling management of medical staff;3.Excellent energy-saving hospitals adopts design methods in outpatient public space of miniaturization,facing the outside,few and small rooms with daylight,and floor radiant cooling and heating.Typical hospitals in China has the characteristics and problems in outpatient public space of large amount of out-patients,improper design of the room side facing outside,huge area and great height of outpatient hall,strong connectivity of upper space of outpatient hall.Based on these conclusions,the paper proposed strategies of optimization and adjustment from four aspects: adjustment of area and floor height,adjustment of connectivity,adjustment of room side facing outside and adjustment of energy supply;4.Put forward the demand-driven ventilation strategy based on the behavioral information of medical crowd,and Prove it effective for improving thermal comfort and reducing energy consumption in outpatient public space.The main significance of this study lies in: 1.This paper integrates the improvement of medical comfort and the reduction of energy consumption,and exploer the optimization strategies for outpatient public space from the perspective of behavior of medical crowd,which not only provides a new idea to solve the contradiction,but also makes up for the deficiency of relevant research fields;2.The research The research method and process which takes evidence-based design as the core theory,and deduce conclusions step by step through multiple field investigations can be popularized and used as a reference for other relevant architectural research;3.Results of the investigation on the public space of hospital outpatient department as well as the corresponding optimization strategies can provide information support and design reference for hospital design;4.Ventilation strategy coupled with its operation steps and verification process proposed in this paper can be submitted to HVAC professional designers to provide new ideas and references for building ventilation optimization.5.The research findings and conclusions can help hospital managers to optimize hospital management and equipment operation. |
