I refer to the Health Ministry's reply (Subsidised wards in newer hospitals better now, Oct 9).
The ministry stated that hospitals have implemented measures including "spot-cooling to bring down the ambient temperature in specific locations".
I saw this being done at two hospitals in the past year.
Spot-cooling in this case refers to several portable air-conditioning units being deployed at every B2/C ward.
Is this more energy efficient than having central air-conditioning?
In the light of recent discussions on doing more for the environment, should we not take a holistic view of this simple issue and resolve it pragmatically?
After all, the wards are already differentiated by the number of patients residing there, air-conditioned or not.
