Commodore and Portswood Energy Study - Two intensive energy studies at the Commodore Hotel and Portswood Hotel in the Cape Town waterfront were carried out. This comprised of detailed energy audit and monitoring of the kitchen, hot water boilers and mains supply. This information served to make recommendations for reducing electricity consumption without capital intensive retrofits. Close interaction with the hotel staff was ongoing and a critical part of making sustainable energy savings. Energy efficiency principles were applied, in conjunction with detailed data, and estimated no or low cost savings are in the region of R20 000 a month. Furthermore, feasibility studies for larger capital intensive projects like heat pumps and solar water heating systems were also carried out.
