Magnitude of Water Consumption
In order to obtain a sense of the magnitude of this number, we will show what only 1 m3 of water is capable of as shown in Box 9.6. It indicates that 1 m3 of water is enough for 13 baths, or 14 washing machine loads, or 28 showers, or 33 dishwasher loads, or 111 toilet flushes (United Utilities Web Site 2015). Another way to show the magnitude of the number is by illustrating the quantity of drinking water supplied to hotel guests. This yields the hotel annual consumption of 165,564 m3, hence the water consumption per day will be 453.6 m3/day equivalent to 453,600 L, and the average litre of drinking water needed for adults is about 1.89 L (The Cleveland Clinic 2007). Therefore, the amount of water used per day by the hotel is capable of providing drinking water for 240,000 persons.
The environmental impact of transport is significant due to the fact that it is a major consumer of primary energy and burns most of the world’s gasoline, estimated at 33 %. This creates air pollution, including nitrous oxides NO2 and particulates, thus it is a significant contributor to global warming through emissions of CO2 (Fuglestvedt et al. 2007), for which transport is the fastest growing emission sector. By sub-sector, road transport is the largest contributor to global warming (Fuglestvedt et al. 2007).
Hilton Ramses hotel has a great transportation impact since the hotel overlooks the main square of Abdel Meniem Riyad and Downtown Cairo which is considered the central transportation area since it is close to the 6th October Bridge. This would place the hotel in a highly congested area, and thus it affects traffic. This point has been examined and analysed in the following part. The focus is centred on the current situation and the impact of the hotel on traffic and transportation in terms of CO2 emission excluding the construction transportation phase.
