Drafting Efficient (Time & Cost) Technical Examination ofEnergy-saving and Permanent Counter-measures4 different perspectives for ECO-Tuning initiative

1. Tuning based on design concept (Optimization)→ 【example】 usage of “outside air” in kitchen while quiet time after 2 pm

2. Tuning for fixing initial failures→ 【example】 change “sensor positions” for getting proper data
Initial failures are inevitable, we must find unusual data and fixing them

3. Tuning customized for usage conditions→ 【example】

Usage condition changes while long use of facilities,
Therefore we must optimize systems and facilities.

4. Advanced tuning for facility/equipment→ 【example】 Control parameters for optimization of air-conditioners,lighting

Ideal “TUNING” is achieved through 4 perspectives above mentioned

Example of ECO-Tuning

13◆ Intaking outside air for air-conditioner operation was theoriginal design concepts. Monitoring data was the key to find.
beforeafter【design concepts】
Kitchen air-conditioner is designed tointake outside air with manual operation.
Employees did not use this function.
This fact was detected by electrical
power monitoring.

【Measures and Results】
This power monitoring data is informed
to employees, and asked to improve withthe manual operation.
Electrical power consumption and heating
value were vastly improved.

We hastened HVAC’s turn-on and extended turn-off for 1 hour.
As a result, peak time of energy consumption was moved up for 1 hour and decreased.
Energy consumption in 2011 was lower despite the fact that average of outdoor air temperature in 2011was higher than in 2010 (avg.1.5℃ higher).
