1. Energy Management for Bank Branches
April 2008

2. The Energy Challenge for Banks
Most of the energy consumed in bank branches comes from lighting and air-conditioning
Most bank branches have uniform design & mandate the temperature settings
In order to maintain the temperature range, cooling and heating may occur at the same time and thus wasting energy
Sensing equipment does not work properly due to partitions and poor location of thermostats
There is no absolute comfortable temperature range from one day to the next
A comfortable environment is relative to the outside temperature and weather conditions

3. The Energy Challenge for Banks (cont.)
Lights are often run at full power despite the fact that uniform indoor light is the goal
In good weather condition, outside sunshine can improve the lighting efficiency allowing lights to be dimmed
Operation management
Lights and air-conditioners are left on unnecessarily often by after hours cleaners

4. The Basic Concept of Energy Efficiency
Reduce power (kw) consumption
Reduce electricity (kwh) consumption
How to achieve that?

5. Efficiency of Power Consumption
Use dimmable electronic ballasts & fluorescent lamps area lighting
Electronic ballasts have a much higher light & energy efficiency compared with traditional ballasts

6. Efficiency of Power Consumption (cont.)
Reduce illumination levels
Leverage natural light source
Light level can be safely reduced at non-critical areas such as hallways, lobbies, waiting rooms, mechanical rooms and rest rooms
Time schedule
To insure lights operate only when needed

7. Efficiency of Power Consumption (cont.)
Adjust temperature set point based on outdoor and indoor temperature and humidity
People feel most comfortable if indoor temperature is only a few degrees away from the outdoor temperature

Outdoor multi-sensor

8. Efficiency of Power Consumption (cont.)
Project strategy
Every bank project is a retrofit project
Apply specific strategy
Great results if planned and implemented carefully

9. Control/Monitoring System
What Can be Done? １
Sensor System ２
Control/Monitoring System
　● Temp /Humidity (Outdoor / Indoor)
　● Lux (Outdoor / Indoor)
　● Power consumption
　● Lighting control (Outdoor)
　● Lighting control (Indoor)
　● A/C control ３
Analysis System ４
Remote Management
　● Temp / Humidity record
　● Lux record
　● Power consumption record
　● Remote maintenance
　● Retrieve data log remotely
　● Receive fire alarm and security alarm
● Remote disconnect if required

10. Lighting Control Strategy
Lighting should be maintained to an actual inside lux set-point. As outside ambient light increases/decreases inside lighting is brightened or dimmed to maintain constant light levels

11. Lighting Control Strategy (cont.)

Lux Sensor
Ambient Inside light
Inside Lighting
Lighting control by inside set point
Adjust lighting according to changing ambient conditions

12. Air-Conditioning Control Strategy
Air-conditioning set point should be adjusted for both outside temperature and humidity. This is particularly important for branches where the public is entering from the outside. Apparent temperature will vary as humidity increases

13. Air-Conditioning Control Strategy (cont.)
Indoor Temperature / Humidity sensor
The main function of air conditioning controller is to pick up indoor / outdoor temperature and humidity to control the office temperature
In addition, the controller also adjusts to the best indoor temperature based current conditions
A/C Controller
Outdoor Temperature / Humidity sensor

14. Power Management
The ultimate goal is to reduce power (kw) consumption & electricity (kwh) consumption
The first step is to become energy conscious
Apply energy meters to the switch board
Record electricity consumptions of lights, air cons & other electrical devices
Analyze power consumption

15. Remote disconnect lights or appliances if necessary
Remote Monitoring
Monitor lights at branch ATM’s, send instant SMS when light failure occurs and have 24/7 fast response to maintenance
Monitor both air con and lighting remotely for all branches and report any lights/air con running at strange times.
Remote disconnect lights or appliances if necessary
Receive fire alarm under fire alarm situation
Receive security alarm when break-in occurs
Retrieve data logs for trending and analysis

16. Challenges of Implementing Control Networks
The network must be robust and reliable enough to deal with control at each local level
Allow for seamless aggregation of information from hundreds of locations and future expansion
The network must be secure and easily integrated into the bank’s existing IT infrastructure
Support seamless remote connectivity
Support Open System technology and interoperability
Future-proven
