Description of the building:
TVB City is a 110,000 square-metre facility, that comprises the following buildings:
- Main Block - a 11 storey building used as generic office building/hotel scenes for TVB's modern dramas
- Drama Studio Block - used for shooting drama shows
- News and Car park Block - used for news and information which car park opening 24-hours 7-days a week
- Variety Studio Block - used for shooting variety and specials
- Workshop Block
- Link Block - with Canteen and Cafe facilities
Retrofitted initiative:
HVAC Air Handling Unit System (with Variable Speed Fan):
Replace pre-filters and bag filters with Nanofil Low Energy Air Filters (LEAF) at HVAC Air Handling Unit System.
What have been/will be done on TVB City?
Replace the existing pre-filter + bag filter with Low Energy Air Filter (LEAF)
 
Observed benefits other than energy saving:
- Over 50% reduction of filter waste
- Around 240 tonnes reduction of carbon emission (based on 70 sets of HVAC Air Handling Unit system)
- Maintenance resources reduction (manpower, cost, time) on changing filter
- IAQ improvement, particularly ultra-fine particles (around 50% reduction on PM0.3 and PM2.5)
General observations of the retrofitting project:
- Reduce filter storage space requirement, utilize space usage.
- Replacement of HVAC filters is easy and fast. Does not affect the tenants. Positive comment from contractors.
- Pressure drop across air filters substantially decreased in AHU.
- Electricity consumed by HVAC system is reduced.
- Tenants are happy as a result of IAQ improvement.
