Ratio of the floor space area by department categories

Ratio of the consumption of energy by department categories

While the energy density is small, the working hours are throughout the day and since the ratio of the floor space area is large, this is the department with the largest amount of consumption of energy.
The amount of the consumption of energy is greatly impacted by whether or not air conditioning will be operated at night in the general wards.
Moreover, the amount of the consumption of water is highly impacted by the number and time during which the patients are in the hospital rooms and for this reason, the amount of the consumption of water is also largest for this department. This can also be seen in the fact that there is a high correlation between the amount of the consumption of primary energy and amount of the consumption of water as shown in the figure.

1. Attention should be given to avoiding excessive cooling or excessive heating.
2. When the outside air is fresh, windows should be opened and the air conditioner shut down to the extent possible.
3. The adoption of a zero energy band method for the 4 pipe method should be reviewed.
4. Water conserving frames should be used at places where water is used for rinsing.
5. Attention should be given to whether or not the water supply pressure is excessive and the pressure should be adjusted to an appropriate level.
6. Does the shower allow for easy adjustment of the temperature?
   -->If not, review should be given to replacing the system.

While the electric density is medium, since the working hours are short, the amount of the consumption of energy is about 10% of the total. Since there is large people traffic, infiltration of outside air represents a large load on the air conditioning. There is a significant difference in the energy density by the time of the day.		Points for Measures for Promoting Energy Conservation A windbreak room should be installed at the entrance. The operation of the air conditioning should be stopped early. Intake of external air should be increased or decreased depending on the number of patients such as through schedule control. The lighting facilities should be switched to three levels of lighting intensity based on the time of the day.

Since the ratio of the floor space area and energy density are both large, the ratio of the amount of the consumption of energy is second to the hospital ward and since the amount of the consumption of steam particularly for sterilization is large, this department may be said to consume the largest amount of heat.
A characteristic of this department is that in addition to heat, the use of water and hot water supply is also large.
Moreover, since there are numerous advanced medical instruments such as the MRI with respect to which it is not possible to shut down the electric power source even during the night, the standby electricity required is large and the department is characterized by the large amount of the consumption of electricity during the night.

1. The washing work should be undertaken efficiently.
   -->Such as through collecting into similar types of instruments and avoiding keeping the water running
2. Articles that are to be sterilized should be washed prior to the sterilization.
3. Care should be taken to avoid excess loading of the autoclave
4. The external pipe of the autoclave should be adequately preheated.
5. Cleaning and inspection of the autoclave should be undertaken periodically.
6. Review should be given to turning down the air flow in surgical theaters that are not in use to the extent that minimum positive pressure may be maintained.
7. Electric power to medical equipment should be shut off to the extent possible at night and on holidays.
