About 117 government office buildings in the Tokyo metropolitan, we have been surveyed to investgate 1) the important degree of the building equipment function in case of emergency, 2) the ratio of essential function in case of emergency comparative to normal function, 3) the hours for which the facilities can be operated normally and 4) the desirable hours for which activities should be kept in the emergency. Based on the differences of the characteristics of districts and buildings respectively, the buildings are classified into 3 groups, Ta group (government office buildings which have superior fuction for emergency activity), Tb group (normal government office buildings which are located in an area that the sum of the population is over 200,000 and below 700,000 during the day and night), Tc group (normal government office buildings which are located in an area that the sum of the population is below 200,000 during the day and night). The result of this study can be concluded, 1) Electricity, communication and water supply function is more important function on buiIding service, 2) The hours that the facilities can be operated normally and the desirable hours for which emergency activities can be continued is 64 hours,444 hours for Ta group, 36 hours, 109 hours for Tb group and 25 hours, 117 hours for Tc group respectively. The gap between these two hours means the present facilities are not enough for the emergency. 3) A supply pssibility of the electric and water supply function, which is very important in the case of emergency, is also examined with the present equipments.
