3 3, ', & Hot water demand can be assumed as follows. For bathing (using bucket water) = 15 litres per person per bath (one bucket) For shower bath = 25 litres per person per bath For tub bath = litres per person per bath For cooking = 5 litres per person per day For washing clothes = 10 litres per person per day For washing utensils = 5 litres per person per meal For making tea/coffee = 150 ml per person per cup (Consumption figures may vary, depending on the lifestyle, age, habits, and weather conditions) UNDP/GEF is conducting a study (under publication) on assessing the potential of solar water in India. Some indicative benchmark numbers that are available for estimation of solar water requirement for various applications are as follows: Hotels: 4 star and above: 150lpd/room 3 star : 125 lpd/room 2 star and below: 50 lpd/room Hospitals: 30lpd/bed for government/private hospitals 190lpd/bed for multi speciality hospitals Hostels: 30lpd/student Applying the above, the hot water demand per bed/person for hostel/guest houses can be estimated as follows: For bathing (using bucket water) = 15 litres per person per bath (one bucket) For cooking = 5 litres per person per day For washing clothes = 10 litres per person per day For washing utensils = 5 litres per person per meal Hence total hot water demand can be estimated as 30-35lpcd and hence 6 beds would require a minimum of lpd (say 200lpd) instead of 100lpd specified in the current byelaw. The current byelaw provision shall meet 50% of the water requirement Similarly, for industrial canteens, Applying the above, the hot water demand per worker can be estimated as follows: For cooking = 5 litres per person per day &- #. /0 1 For washing utensils = 5 litres per person per meal Hence per person requirement is about 10lpd and hence one 100 lpd is required per 10 workers, in place of 50 workers. The current byelaw provision would thus meet Achieve 20% of the Energy hot water Efficiency need in for Bangalore this application. City The apartment blocks that have dwelling units lower than 200 sqm should also be covered by byelaw and provision for solar water system should be mandated. In case of apartment buildings, the available roof area could determine the capacity of solar water to be provided.
