MAINTENANCE PRIORITY AT UNIVERSITY HOSPITALS AND ACADEMIC FACILITIES BASED ON MAINTENANCE RECORDS

The main tasks of maintenance workers are handing Failures and Troubles (F/T) at existing buildings and such tasks need to be handled rapidly. The time taken to repair an F/T is one of the most important evaluation elements for building performance and maintenance work quality. The time taken to conduct repairs depends on individual aspects of the F/T, such as the technical difficulty of the repairs and how busy the maintenance workers are. If multiple F/Ts occur simultaneously at the same site, the workers handle them based on a priority in terms of the importance of the objects or their effect on users of the facility. This time, we received maintenance data from two university hospitals. They both have academic facilities and incidental facilities at the same site. The maintenance priority reflects the difference between them. The main purpose of this research is to explore the relationship between the maintenance priority and the time to repairs. As the F/T number increases at a site and maintenance workers get busier, the time-to-repair for the hospital facility gets slightly longer. On the other hand, as the F/T number increases, the time-to-repair for the other groups gets significantly longer. Since indoor environmental management is very important in hospital wards, the maintenance priority can be higher than the other groups.

STUDY ON MAINTENANCE CHARACTERISTICS OF HOSPITAL FACILITY BASED ON MAINTENANCE RECORDS

Once, buildings are completed and started to use, various failures and troubles occur on a daily basis. However, while they have never released and analyzed the data, the basic information for the maintenance plan is insufficient. The purpose of this study is to clarify the maintenance characteristic of hospital facility and give the fundamental information for the maintenance plan. The maintenance records have ever been collected from five hospitals. First, this paper gave an outline of the collect data and the way to adjust it for detail analysis. Next, the employment systems of the maintenance workers in each hospital were shown and were compared with the office building one. Based on all equipment data, the maintenance characteristic of hospital facility was brought out from the total view point. And the feature of the failures and troubles were shown by the analysis on the architectural medical items which are most unique of all.

RESEARCH ON ENERGY AND WATER CONSUMPTION AT LARGE-SCALE HOSPITAL

The maintenance records at a certain large-scale hospital, the total floor area 75,311m2 hospital building and 12,793m2 health checkup center, are investigated. The monthly and daily data of electricity, gas and water consumption are obtained. The paper presents the features of the hospital and the outline of the buildings at first, and then annual or monthly electricity and gas consumption, including CGS operation results, and water consumption are analyzed. Then, using the daily data, the correlation between the energy consumption and the enthalpy of outside air, the difference of the data on holidays, and the annual characteristics of energy and water consumption at weekdays are presented. The paper also shows the daily maximum electric power and the restraint kW-value for the electricity demand management.
