Portland Marriott Advances Greening the Hospitality Industry
Once a vacant bank building, the Marriott Courtyard Portland City Center was the first hotel in the Marriott chain to achieve LEED Gold certification. The 1980s-era office building and adjacent site now offer 256-guest rooms, meeting and convention space, fitness center and restaurant. The renovation included a new shell, three additional floors and new mechanical systems. The hotel uses 28 percent less energy than a property of comparable size due to daylighting, efficient air-handling systems and heat pumps in guestrooms and meeting spaces.
“From the sustainability point of view for existing buildings, especially when you look at the hospitality market, if you build one new LEED Platinum building, it’s going to have impact and you’re going to have fairly high energy savings. But if you look at a small hotel development or even a smaller group that may have 20 hotels for example, if they can improve their energy consumption just 10 to 20 percent by doing something with their existing buildings, that’s going to have a greater impact than the one LEED Platinum building. It’s a multiplier effect,” said Gary Golla of SERA Architects.
According the project architects, the construction cost premium to build the hotel to the LEED Gold standard was 1.2 percent. Factoring in state and local incentives reduced the net premium to 0.25 percent, about $110,000. The estimated payback time for water and energy cost savings is 18 months, and the hotel expects to save about $675,000 in operating costs over ten years. Dual-flush toilets contribute to an estimated 26 percent less water use.
