Consumes a big proportion of electricity as compared to other tourism sectors.
The use of water in a hotel is extensive and it is used in many different ways, such as cold water for kitchen, laundry, drinking, circulation for air taming hot water for guest bathrooms and flow for space heating.
Water consumption at this rate that to without monitoring, will likely guide to water shortages.
Another factor that affects water is not only consumption but also contamination.

29. Project summary
The ITC Hotel building is located at Guntur. The building is of commercial use with 2
Basement floor + Ground floor+ 9 floors. This new commercial use building has an
approximate gross floor area approximate 238,722 square feet, and includes Guest
room, meeting room, reception, Gymnasium, Dining hall, kitchen, Restaurant. The net
air conditioned area of the project is approximate 89,652 square feet.
Modeling methodology
The Proposed Building has been evaluated on the basis of the methodology outlined
in Appendix G, The Performance Rating Method of ASHRAE/IESNA 90.1-2007. Visual
DOE 4.1, a front-end to the DOE-2.1E engine, has been used as the simulation tool.
Annual hourly energy simulations are performed to quantify the anticipated HVAC and
lighting energy savings of the proposed building design. The two building models
(Baseline and Proposed) use identical climate zones, layout, occupancy, plug loads, and
schedules.

34. Climate summary chart
The Baseline building is an ASHRAE 90.1-2007 compliant building based on the
requirements outlined in Appendix G of the Standard. The Baseline building residential
spaces System -2 Packaged terminal Air Conditioner and Non-residential spaces System
6 – Packaged rooftop VAV with reheat. Envelope requirements are based on the
ASHRAE minimum values for a building located in Climate Zone 1 – Hyderabad, India.
No external shading devices are included in the Baseline building model.
The Baseline building performance is the averaged results of simulating the building
with its actual orientation and after rotating the entire building 90, 180, and 270
degrees as ASHRAE 90.1 requires.
The proposed model incorporates all the energy efficient features as designed. The
energy cost savings between the baseline and proposed models is used to determine
the total number of LEED® credit points available under Energy and Atmosphere Credit
1 (EA1) - Optimize Energy Performance. The total number of EA1 points achievable for
the project under LEED_India_NC_2011 rating system is as under:
