On the basis of this, the corresponding optimization strategy is putforward in order to help to update and improve the emergency design of interior space in multi-storey residential buildings.Keywords: Public Health Emergency; Interior Space of Multi-Storey Residential Building; Emergency Design Update;ResidentialIntroductionThe outbreak of novel coronavirus at the beginning of 2020 has aroused great concern all over the world. However, dueto the lack of objective understanding of epidemic prevention emergency design in traditional residential buildings, theemergency response ability of indoor space in the face of epidemic situation is poor. Therefore, it is very necessary to analyzethe new demand of residential buildings under public health emergencies and to build an updated design framework topromote resilience and epidemic prevention.1. Understanding Public Health Emergencies: From the Promotion ofResilience and Epidemic Prevention1.1 Public Health Emergencies and Residential Indoor SpaceIn the face of this menacing epidemic situation, the epidemic prevention board of residential indoor space has graduallybecome a research hotspot, and family protection has become a feasible way to deal with the epidemic situation [1]. In view ofhow to improve the sanitary and epidemic prevention ability of residential indoor space, it is necessary to systematically putforward emergency measures of indoor space epidemic prevention combined with domestic and foreign residential healthprevention and control experience, in order to provide reference for the improvement of residential indoor epidemicprevention ability under such public health emergencies.1.2 New Requirements for Resilient Safety of Epidemic Prevention SupportIn order to deal with public health emergencies, many countries have explored to improve the emergency responsecapacity of epidemic prevention [2]. For the United States to promote the construction of "disaster prevention community"throughout the country; Japan puts forward the concept of "public assistance + co-assistance + self-help", and strengthens thecooperative relationship of "public rescue + mutual rescue + self-help". Australia does not put forward the concept of"prepared community", which aims to formulate different emergency plans according to different types of public healthemergencies, and update and improve each plan [3-5]Generally speaking, in dealing with public health emergencies, the research from the perspective of residential buildingsis less and less concerned, which leads to the lack of emergency capacity of indoor space in residential buildings.Urban Transportation & Construction- 2 -2. Reflection on Public Health Emergencies: the Concept of Resilience andDesign Framework2.1 the Connotation and Logic of Resilient CitiesResilient city means that when a disaster occurs, the city can withstand the impact, respond and recover quickly,maintain the normal operation of the city function, and better deal with the disaster risk in the future through adaptation. Withthe continuous deepening and expansion of the study of resilient cities, the world has set off a new wave of resilient urbanplanning and practice, and this concept and strategy has been gradually applied to all kinds of unknown risk fields.2.2 Resilient ResidenceIn the face of public health emergencies and complex environment, resilient housing is mentioned as an extension ofresilient cities to form a complete resilient vertical system. With regard to resilient housing, first of all, the positive effect ofspatial combination promotes the improvement of spatial resilience. That is, the arrangement of the space is based on thereasonable organization of the indoor streamline in order to improve the toughness of the space. Secondly, integrate theelements of indoor space from the perspective of epidemic prevention and emergency, and actively organize the indoor lineof defense to deal with public health emergencies.3. Analysis of Public Health Emergencies: Current Situation of EmergencyCapacity of Residential BuildingsSelect the main urban area of Handan City as the study area, select five representative communities for questionnairesurvey, carry out digital visualization analysis of indoor space, and get the evaluation of residents' emergency ability ofindoor space; and carry out sequential regression to analyze the differences of the impact of different indoor space areas onindoor epidemic prevention under public health emergencies. 250 questionnaires were distributed, 227 were valid, and theeffective rate of the questionnaire was 90.08%.3.1 Questionnaire Survey and AnalysisThe construction age of the five communities from far to near is Luochengtou No. 4 Hospital, Railway Courtyard,Guangtai District, Guanghua Yuan North District and Asia-Pacific Century Garden. From the analysis, we can see that theresidents' evaluation of the multi-storey housing built in different periods is different. And in the overall evaluation, thesatisfaction of Asia-Pacific Century Garden is the highest, while that of Luochengtou No. 4 Hospital is the lowest.According to the sequential regression of residents' evaluation of indoor space factors, it is found that porch space,kitchen space and toilet space have a significant impact on indoor epidemic prevention evaluation.3.2 Summary of Indoor Space ProblemsAccording to investigation and analysis, there are the following problems in residential indoor space in epidemicprevention emergency: mutual nesting of functional space, unreasonable layout, poor flexibility of functional space and poorquality of ventilation and lighting. Therefore, based on the update of emergency capacity, the following paper furtherdiscusses the update of epidemic prevention and emergency capability of indoor space in multi-storey residential buildingsunder public health emergencies.。4. Dealing with Public Health Emergencies: Emergency Update DesignStrategy4.1 Enter the Household to form an Independent Space to Isolate theSource of InfectionVolume 8 Issue 2·2022 - 3 -In the household space, you can set up the garden and the porch space to form an independent space. In this space,functions such as changing, washing hands, placing things, hanging ironing and hanging receiving clothes are placed in theorder of use, so as to meet the eliminate virus epidemic prevention process of residents entering the room from outdoor toindoor and the process of changing clothes from indoor to outdoors, so that residents can better complete the protection underthe epidemic situation.4.2 Optimize Indoor Layout and Improve Layout Flexibility4.2.1 Bathroom Space LayouAs the residents pay more attention to the epidemic situation, the residents are more inclined to the arrangement of thetwo sanitary facilities. In the layout of the toilet, the multi-function is arranged in the same space, the dry and wet separationis not carried out, and the toilet is in a moist state for a long time and the utilization rate is low. In order to avoid conflictsamong residents, the toilet layout needs to do dry-wet separation or three separation to facilitate the clean eliminate virus ofthe toilet space, and improve the epidemic prevention ability of residents at home.4.2.2 Layout of Indoor Isolated SpaceIn case of public health emergency, residents can choose indoor near-end or far-end rooms as isolation space to reducethe streamline crossing between isolated and unisolated residents. In the layout of the isolated space, the needs of isolatedresidents such as rest, grooming and leisure should be met.Fig. 1 Schematic Diagram of Isolation Space Design4.3 Create Functional Composite Space and Improve Space UtilizationTo improve the space utilization, it can be designed in both horizontal and vertical dimensions. In the horizontaldirection, light partition can be used to complete the mutual transfer and borrowing of space, expand the living room spaceand form a closed porch to facilitate family epidemic prevention and meet the needs of residents. In the vertical direction, thenear-ground space can use multi-functional furniture to complete the functional space conversion in different periods; in theindoor top space, more lockers are placed to increase the indoor storage space to meet the storage needs of residents underpublic health emergencies.4.4 Improve Indoor Ventilation and Lighting and Improve Living QualityIn the event of a public health emergency, a reasonable form of natural ventilation can maintain the appropriate indoortemperature and humidity and contribute to the circulation and replacement of indoor air. In order to improve the quality ofindoor ventilation, it can be considered from four aspects: selecting separate traffic core, setting suitable air inlet and outlet,selecting suitable air inlet form and window sterilization.To improve the quality of indoor lighting, first of all, we can expand the building room to expand the building lightingsurface, and at the same time facilitate ventilation. Secondly, to ensure the transparency of the windows, to ensure the normaluse of windows and natural light to enter the room normally. Finally, window holes can be designed on the indoorlightweight partition to make natural light enter the space, and transparent but opaque glass walls or other material partitionscan also be used to replace concrete walls to form a more transparent and bright indoor environment.Urban Transportation & Construction- 4 -5. ConclusionWith the frequent occurrence of public health emergencies, the design and practice of emergency renewal of indoorspace in residential buildings has become the focus of architectural research. Taking the present situation of the main urbanarea of Handan as an example, according to the analysis and summary, this paper puts forward the design to enhance theemergency ability and resilience of epidemic prevention in indoor space from four aspects: independent space, interior layout,functional compound space and daylighting ventilation. in order to provide a feasible basis for the improvement of indoorspace emergency capacity of multi-storey residential buildings.References[1] Xiao, W, Song, Y, Quick response: thinking on the Anti-epidemic Design under the epidemic situation of COVID-19 [J].Journal of Architecture, 2020 (Z1): 55-59.[2] Cao, LJ, Zhang, Y, Zhou, XD, etc. Analysis of influencing factors of COVID-19 's self-health empowerment in the earlystage of epidemic from the perspective of family collaborative protection [J].
