Retrofitting Strategy |
Using web-cam people counting and recognition system for optimising energy efficiency and operational performance of air-conditioning and building transportation system
|
|
Different types of people counting technologies are available in the market. Popular choices include infrared beam counter, thermal count sensor, video-based count senor and light detection and ranging (LiDAR) sensor.
By integrating people data into BMS or AI energy optimisation platform, HVAC system operation can be better optimised.
|
| Consideration
|
- Knowing the number of people in and out of the building, the AI energy optimisation platform can accurately predict the cooling load required and operate the optimal number of chillers to be operated. Fresh air intake can also be reduced to meet the minimum occupancy requirements.
- By counting people inside lift car and waiting in lobby, the smart lift system can perform many functions such as triggering by-pass (skip floors) when the lift is full or no people waiting in the lobby, sending a right number of lifts to serve the people in the lobby, etc.

| Estimated Saving
|
The retrofit strategies is a mixture of different strategies and the saving estimation should be make reference to other single strategies.
