| Hotel Engineering
Engineering department
in the hotel is responsible for operating and maintaining
the entire building services systems. Around 1.5 to 3% of
the total hotel financial turnover is spent for the engineering
related Repair and Maintenance (R&M). The expenditure
for engineering R&M includes AC fittings, dampers, thermostat,
refrigerant gases, carpentry, electrical items etc. The
major portion, say around 15 to 20% of engineering R&M
is spent for the Heating, Ventilation and Air Conditioning
(HVAC).
The following is the percentage break-up of energy consumption
by various utility areas of engineering department.
- HVAC 25 – 30%
- Lighting 18 – 22%
- Kitchen 10 – 15%
- Lobby 10 – 15%
- Elevators 02 – 04%
- Banquets 02 – 04%
- Others 10 – 25%
Environmental
Impacts
To maintain the electrical, mechanical and plumbing
system & equipment, the engineering department consumes
enormous amount of resources and generates disproportionate
amount of waste. These wastes has an adverse environmental
impacts, some of them are listed below.
