UMUC experimented with bamboo floors but ultimately chose not to use that product for that purpose because of durability concerns. Instead, the hotel used the sample bamboo to line the interior of the elevators.
Operations Currently, Marriott recycles back-of-house paper, corrugated cardboard, and rigid containers, and there is recycling available in the guest rooms. Food and beverage waste from restaurants and banquet events is recycled– including glass, metal, plastic, paper, and cardboard. Food is also composted – up to 1,000 pounds per day! Diverting this food waste from the trash dumpster is saving money as the per ton charge to remove composting material is half of what it costs to remove solid waste. In addition, the hotel uses only china and silverware (not paper and plastic) in the conference areas, and retired terry cloth towels become cleaning rags. Concentrated green cleaning supplies come from EcoLab, but they are not Green Seal certified, and are purchased in bulk to minimize waste from individual bottles. Marriott is currently consulting with UMUC’s maintenance provider to obtain information regarding the Green Seal certified cleaning solution used at other UMUC facilities. The hotel donates unused guest room amenities such as shampoo and conditioner to a local woman’s shelter and they follow the Green Meeting Industry Council’s (GMIC) guidelines for Green Meetings. Finally, in an effort to minimize paper usage, all guests can request electronic receipts at checkout and meeting planners can receive all planning materials electronically as well.
3. Energy Energy efficient features that are incorporated into the core of the ICC building include Kone elevators, fluorescent lighting, indirect lighting, energy recovery units, CO2 sensors on the air handlers and an insulated building shell. The efficiency features represent a 19% reduction in energy consumption as compared to the ASHRAE 90.1-1999 standards. (This calculation does not include energy consumed in lamp lighting, which is a large part of ICC’s lighting, because ICC is evaluated with LEED version 2.0). The Kone elevators are 34% more energy efficient than standard elevators because of the overhead cable pulley system that they use. Fluorescent lighting is used for all overhead lighting and daylighting provides some indirect light. The combination of energy recovery units with CO2 sensors on the air handlers is the most energy efficient technology in the ICC addition. The energy recovery units create an energy saving system that capture energy from outgoing, exhaust air and transfers it to the incoming, outside air. This narrows the range that the outside air needs to be heated or cooled. As a result, the air handlers heat or cool tempered air and the CO2 sensors reduce the amount of outside air that is introduced to the building. The combination of these systems creates a much more energy efficient system that provides a healthier indoor environment. The ICC building shell is also efficient through its low-e windows and roof construction. The windows are low-e glass windows that allow daylight to enter. Since the windows are operable however, the amount of energy efficiency realized is more difficult to control. The roof is constructed entirely of recycled rubber material. On the flat section, a white reflective roof has been installed that absorbs less solar energy than the steeper section of the roof that is a dark red color (that was chosen to match the design of the original hotel).
