Hi, We are working on a project in Dubai. The building is 55% office and 45% hotel. There is no floor level metering and the building has only one electricity meter. I would like to know the challenges that we will be facing to acheive the required enegry star rating. May i know your views please. Thanks Sriman
Can you verify which rating system and version you are considering?
My suggestion is to start using ENERGY STAR Portfolio Manager starting with an office facility and then entering a separate space type of hotel and see what happens assuming you can use Case 1.
Theoretically the office space type should be eligible for facilities that are at least 50% office. However, in practice this arrangement may not be intended for buildings where 45% of the facility is a hotel, and likely has a higher EUI than the office portion of the building.
If the results don't make sense, USGBC may be able to help you develop a Case 2 calculation.
