50% cut in energy consumption for the Sheraton, Vancouver
Grundfos has conducted a pump audit and consequent installation
of Vancouver's Sheraton Wall Centre pump system, with immediate
50% cut in energy
The megalith Sheraton Wall Centre set against the Vancouver,
British Columbia skyline created a unique pumping challenge to the
Grundfos team. The south tower of the building is an impressive 49
stories high presenting the challenge of sustaining water pressure
at height. Additionally how could the system provide maximum
efficiency and thereby build upon the green remit of this
building's pumping systems?
Naturally the Sheraton turned to Grundfos as pioneers in
reducing electricity consumption through energy efficient pumping.
Grundfos conducted a pump audit of the 13-year-old pump system and
recommended the MPC BoosterpaQ with CR pumps at variable speed
including a controller package. The compact size of the MPC
BoosterpaQ avoided breakdown and removal of the original system.
The switch to the new system took just three hours ensuring the
guest experience remained unaffected.
Almost immediately the financial benefits of reducing
electricity consumption could be seen. The variable speed pumps are
predicted to reduce electricity consumption from 192,000 kWh per
year to 58,000 kWh per year, effectively supplying the entire south
tower with a strong water flow for around $100 a month in energy
