The Jaypee Vasant Continental certified as ISO 9001/2008, ISO14001/2004, ISO /2005 & recently received ISO 50001/2011 through Quality Austria, A luxury business hotel with modern & contemporary facilities located in the heart of the capital. ENERGY PROFILE The Jaypee Vasant Continental Hotel Jaypee Vasant Continental has been aggressive & consistent performer for energy conservation; the sources of energy for JVC include electricity from the grid, HSD for DG, PNG or HSD for boilers, LPG and PNG for kitchens. The total energy bill for was Rs Lacs (electrical and thermal). Electricity consumption The connected load is KW. The electrical energy consumption for the last 02 years is given in the following figure: 349

This is to ensure to focus on those areas which have potentials to conserve energy. To formulate this thought process hotel has divided its building /areas/equipment into three different zones i.e. high, medium & low energy intensive zones. This helps in understanding the level of monitoring needed. 350

3 Energy consumption zone wise division of equipment Energy conservation efforts Training & awareness In order to achieve the energy conservation target and align with our energy & environmental policy necessity of training and awareness cannot be ignored. Energy Conservation posters have been placed at various locations which includes all back of the house areas. Process & equipment operation cost posters/signage Cost details of various process and equipments have displayed at numerous locations to educate the team about the cost proposition in terms of energy consumption & its potential on energy saving. Project Implementation HVAC 1. Replacement of Condenser Pump To align with energy conservation objective for reduction of energy consumption of water pumping system.a detailed energy audit was carried out through M/S Kirloskar & it was found that the condenser pumps operating at low efficiency as low as 48.24% (flow rate 1600 GPM, 35 Mtr. Head). As per finding for suitability of the equipment M/s Kirlsokar suggested for energy efficient corrocoated Kirloskar Pump 351

4 with 37 Kw IE2 Motor (Model K1225 S) to improve the system efficiency of 74.1%. The detailed energy audit report was approved by the top management for implementation of the same. The existing set up was replaced. The performance test of the installed equipments was checked by M/s Kirloskar and J.V.C. energy conservation team, the result found to be in line with the recommended efficiency. Before: low energy efficient Pump After: New Condenser Pump Condenser Pump Picture (before & after) 2. Replacement of guest room window During internal audit it was observed that air conditioning heat load is very high due to improper heat insulation of the window & balcony glasses. Total 48 room window & 10 no balcony glazing work has been done with insulated vacuumized double glass. The total cost of the project was Rs.16.8 Lakhs. This initiative not only improved the air-conditioning effect but also the noise level & aesthetic of the room. Before After Guest room window 3. Chemical treatment for HVAC equipments & water Controlling of chiller head pressure by periodic chemical cleaning of condenser and maintaining of condenser water parameter through M/s Ion Exchange. Also the 352

5 chemical dosing trend is being regularly monitored. As the chiller condenser & cooling tower remains well maintained thereby we normally use one portion of it except for high humidity period of the year. Chemical cleaning process of condenser & chemical dozing log sheet 4. Energy Efficiency Enhancement of Drives Efficiency enhancement of pumps, AHU s, FCU s through regular maintenance / necessary modification or replacement. The performance of all the AHU s was measured and it found that some were operating inefficiently. In some cases the power consumption of the blowers was on the higher side even though they were not delivering sufficient quantity of air. The following areas of AHU s were changed to new double skin (better heat insulated) ones. a) Banquet Hall b) Eggspectation Restaurant In addition to that 02 in no AHU coil & 35 Nos Fan Coil Units also have been replaced to achieve better energy efficiency. Before After Replaced AHU &cooling coil. (Before & after) 5. Prevention of heat loss & plugging the duct leakages Checking of chiller line insulation and wherever damages & leakages found, the same has been rectified to avoid the temperature loss. Sealing the duct joints with 353

6 the help of silicone sealant this exercise was carried out for all the distribution duct joints, in order to ensure the cold air leakage practically limited to zero. 6. Resistance free air distribution. Sealing of duct joints. Cleaning of air duct on regular basis for which an expert agency M/s Epsco had been hired to clean all the HVAC ducts through specialized chemicals. This helps us to achieve better air distribution while consuming lesser energy. Power & Lighting Systems Installation of Energy Efficient lighting system The following were the measures implemented in the lighting system at JVC a. Retrofitting of lighting systems Retrofitment of 35 watt halogen with 1 watt LED in the Main Porch. Change of 50w halogen with 07 watt LED in guest floors. Change of 300 W SVL with 150 w metal halide Change of 300w SVL with 17 W CFL b. Timer and photocells provided for all illumination circuit & Human sensors provided in public area to ensure there is no wastage of electricity. Post retrofit Lux level audit has been carried out through in house resources & found the illumination level meets the IES standard. Before After Energy efficient lighting system 354
