As one of the case study for the PROMEEC Energy Management Programme, the Estate office was recently host to a group of Energy Management specialists who were here in Brunei to conduct an Energy Management Workshop. The group consisted of the ASEAN Center for Energy (ACE), Energy Conservation Center Japan (ECCJ) and representatives from Energy Division, Prime Minister's Office.
The site visit started of with a short and sweet presentation by the Mechanical and Electrical Section, Estate Office. The visit was also attended by Estate Office personnel, Dean of Science and a student from the Master in Environmental Management.
After the presentation, the group strolled down to the first location, the Chiller Yard.
The second location is the Female Residential College, where the group had a close look at the boilers currently installed. The hot water from the boilers are used primarily for the showers.
The third and last location visited by the group was the Chancellor Hall stand alone chiller system. Chancellor Hall being newer than the rest of the campus is not linked to the Chiller Yard but has its own system. The same goes for the UBD Mosque, Institute of Medicine and the ILIA Building.
After the hour long walk in the sunshine, the visiting group concluded their findings and made their recommendations.
Some of the recommendations and findings:
- Chiller yard water pump temperature is smooth at 4.7 degrees Fahrenheit ~ possibility of reducing the flow rate of pumps
- To insulate the piping supplying hot water from the boilers ~ maintain temperature
- To turn of most of the exhaust fan during low occupancy time since carbon dioxide levels will be low (less people) and extensive air interchange is not required.
- To explore the possibility of replacing exhaust fan with an exhaust fan that has a heating unit for better and efficient air interchange.
- To consider replacing the 15 year old chillers. Currently, the efficiency is less than 100%.
- Power factor - 0.9 (acceptable)
