“…In a Chinese university, prevalence of self-reported common cold ≥ 6 times in a semester was found to be higher (35% compared to 5%) among students living in dormitories with lower mean ventilation rates (1 L/(s person) compared to 5 L/(s person)) (Sun et al, 2011). In U.S. retail stores, a self-reported common cold infection rate was lower by 43% in stores where ventilation rate was greater (0.5 ACH compared to 1.2 ACH) (Zhao et al, 2015).…”

A B S T R A C TStrategies to protect building occupants from the risk of acute respiratory infection (ARI) need to consider ventilation for its ability to dilute and remove indoor bioaerosols. Prior studies have described an association of increased self-reported colds and influenza-like symptoms with low ventilation but have not combined rigorous characterization of ventilation with assessment of laboratory confirmed infections. We report a study designed to fill this gap. We followed laboratory confirmed ARI rates and measured CO 2 concentrations for four months during the winter-spring of 2018 in two campus residence halls: (1) a high ventilation building (HVB) with a dedicated outdoor air system that supplies 100% of outside air to each dormitory room, and (2) a low ventilation building (LVB) that relies on infiltration as ventilation. We enrolled 11 volunteers for a total of 522 person-days in the HVB and 109 volunteers for 6069 person-days in the LVB, and tested upper-respiratory swabs from symptomatic cases and their close contacts for the presence of 44 pathogens using a molecular assay. We observed one ARI case in the HVB (0.70/person-year) and 47 in the LVB (2.83/person-year). Simultaneously, 154 CO 2 sensors distributed primarily in the dormitory rooms collected 668,390 useful data points from over 1 million recorded data points. Average and standard deviation of CO 2 concentrations were 1230 ppm and 408 ppm in the HVB, and 1492 ppm and 837 ppm in the LVB, respectively. Importantly, this study developed and calibrated multi-zone models for the HVB with 229 zones and 983 airflow paths, and for the LVB with 529 zones and 1836 airflow paths by using a subset of CO 2 data for model calibration. The models were used to calculate ventilation rates in the two buildings and potential for viral aerosol migration between rooms in the LVB. With doors and windows closed, the average ventilation rate was 12 L/s in the HVB dormitory rooms and 4 L/s in the LVB dormitory rooms. As a result, residents had on average 6.6 L/(s person) of outside air in the HVB and 2.3 L/(s person) in the LVB. LVB rooms located at the leeward side of the building had smaller average ventilation rates, as well as a somewhat higher ARI incidence rate and average CO 2 concentrations when compared to those values in the rooms located at the windward side of the building. Average ventilation rates in twenty LVB dormitory rooms increased from 2.3 L/s to 7.5 L/s by opening windows, 3.6 L/s by opening doors, and 8.8 L/s by opening both windows and doors. Therefore, opening both windows and doors in the LVB dormitory rooms can increase ventilation rates to the levels comparable to those in the HVB. But it can also have a negative effect on thermal comfort due to low outdoor temperatures. Simulation results identified an aerobiologic pathway from a room occupied by an index case of influenza A to a room occupied by a possible secondary case.

“…Other issues related to indoor environmental quality are also important for shopping centers. Zhao et al [5] investigated the perceptions of users/occupants of retail buildings and found that the indoor environment, namely air movement, cleanliness, and the smell of stuffy air, had the strongest relationship with users/occupant's satisfaction. Pecoraro et al [6] analyzed a case study of three retail store designs and found that retail store design should not only be based on room efficiency and functionality, but a quality environment by building a retail strategy that has social value, aesthetic, experiential or emotional through store design.…”

The Influence of Performance-Based Building Design on the Strategy of Retail Property in Indonesia

Management of retail property is important in accommodating tenants who occupy retail space and consumers as a retail property business activity. Performance-based Building Design (PBBD) is a concept that can be used in planning and designing so that retail buildings can operate as expected. In this regard, the strategy of retail space contains three indicators of performance that are effectiveness, profitability, and efficiency. This study finds gaps in retail property management design research. Therefore, the purpose of this study is to determine the effect of PBBD application on the strategy for retail property space in Indonesia. A total of 96 respondents were involved in this study. Data were collected through a questionnaire survey to stakeholders who play a role in the development and management of the retail property in Surabaya. The data were then analyzed using multiple regression. From the analysis, it was found that the application of PBBD, namely user/occupant interest, building management, the process of design collaboration had a positive effect, while the risk of loss had a negative effect. This means that the increased application of PBBD, namely occupant interest, building management, the process of design collaboration and reduced risk of loss in retail buildings, can improve the strategy for managing retail property space in Surabaya, Indonesia. A more detailed analysis of each indicator of the retail space strategy shows different results. The result show that the application of PBBD influence to the effectiveness contributes 44.6%, the influence of PBBD application to the profitability contributes 49.4%, the application of PBBD has an influence for the efficiency by 61.5%, and overall, the influence of PBBD application to the management retail property space contributes 68.9%. The results of this research are very important and have implications for retail space planning strategies. What will happen to retail property management at the operational stage, it can be seen through the implementation of PBBD in the briefing and planning stages.

“…Due to the impact on energy demand [1,2], performance and productivity [3][4][5][6][7], the scientific community has addressed significant efforts aimed at measuring, characterizing and optimizing Indoor Environmental Quality (IEQ) in occupied spaces [8,9] especially from the perspective of thermal comfort [10][11][12] and Indoor Air Quality [13][14][15]. Regarding thermal comfort, the literature is mostly focused on residential and office buildings, whereas only relatively few research concerns retail trade buildings [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] as supermarkets, hypermarkets, department stores and shopping malls which strongly affect global energy consumptions. According to available data, yearly energy demand of supermarkets varies in the range from 400-500 kWh/m 2 (in Netherland [32], UK [33], USA [32] and Italy [34]) to 700 kWh/m 2 (in USA and Canada [32]) with an incidence of refrigerating equipment of about 45% [33,35,36] which correspond to about 4% of global electricity consumption [23,37,…”
