MacDonald-Miller recently completed several turn-key energy-saving upgrades to the mechanical and plumbing systems of the Renaissance Hotel. These efforts will save an estimated 1,166,120 kWh of electricity, 1,363,635 gallons of water, and result in a carbon reduction of 814 metric tons every year.
And we’re already witnessing the benefits. After only three months, the upgrades have Renaissance Hotel saving nearly $30,000 on electricity and $9,000 in water/sewer costs. The 75,000 SF hotel was constructed in 1981 with 553 guest rooms, 18 meeting rooms, and 3 restaurants. The project scope included installing two heat wheels used to recover the heat from warm bathroom exhaust air and heat the incoming outside air; adding “smart” Melink® sensors on the kitchen exhaust hoods to turn off when the stoves aren’t in use; and installing AquaRecycle® laundry water recycle system to reduce the water consumption of the washers by 75%! Other facets of the project included motion-activated garage lighting, domestic water booster pump replacement, and connection of conference room heat pumps to the building automation system. All the installations and retrofits were completed with little or no impact to the hotel’s operations. The project team was able to secure incentives that will cover 50% of the project cost – and as the remaining costs are paid through the energy savings, there is no upfront cost to the owner.
These numbers are astonishing, plain and simple. And at MacMiller, we enjoy huge satisfaction in garnering this level of results for our customers.
