When the chefs in our Dubai hotels are preparing meals in a hot kitchen with summer temperatures up to 46C outside, it's important to have a series of cooker hoods going full blast to take away the hot air and replace it with cooler air generated by an air conditioning system.
However, out of peak periods our kitchens are only lightly used - typically for room service orders and advance preparation of main meals.
Because the extraction needs varies with depending on the kitchen activities - full extraction isn't needed at all times. We decided to install heat and smoke detection systems into the hoods that automatically adjust the speed of the fan according to the level of activity.
This saves on electricity by cutting back on unnecessary use and reducing the amount of cool air that is simultaneously pumped in from the air conditioning system.
Energy use was carefully monitored before installation and we have been able to demonstrate a 55% saving in energy and a 46% saving on chilled water needed to cool the fresh air to the kitchen, as well as a 25 year payback period.
"As part of our sustainability strategy, we aim to deliver high performing assets which provide resource-efficient, healthy and productive buildings for our customers, tenants, operators and residents – and which support and enhance the communities and economies in which they are located. Saving energy in our hotels is key to achieving these goals."
