ABSTRACT
The first and best place to consider building energy efficiency is during the design of the building, not when the building has been completed and is in operation. Previous study suggests that the better design of new buildings would result in a 40-75% reduction in their energy consumption to compare with 2000 levels. Large hotels are big energy users in a city. To minimize the influence of differences in hotels’ facilities, the study randomly collected the monthly real energy consumption data, monthly occupancy and building design data of a number of 4-5 stars large hotel (over 100 guestrooms) in Auckland city of New Zealand in a temperate climate withmild winter and in Shenyang city of China with a cold climate. Figure 1 and Figure 2 show monthly minimum, maximum and mean temperatures of Auckland and Shenyang.
