The Davenport Grand Hotel

CASE STUDY: Your New Hotel is Designed for Sustainability

The Davenport Grand Hotel is Designed for a Sustainable Future

The Davenport Grand Hotel in downtown Spokane, Washington includes 716 guest rooms, restaurants, full conference facilities, and hotel support functions including public and valet parking. The Hotel is operated in an environmentally-friendly manner by protecting the health of hotel guests and taking every available opportunity to reduce waste and conserve essential resources such as water, materials and energy. Procedures have been developed and communicated in various ways to engage employees, visitors and guests to participate in sustainable practices which include green cleaning, educating the staff and public about the Hotel’s green features, recycling and promoting alternative transportation.

The building and site were designed and constructed with a goal of attaining Silver Certification in the Leadership in Energy and Environmental Design (LEED®) 2009 (version 3) Green Building Rating program. The project is currently in LEED construction review, and confirmation of certification is anticpated in October 2015. The project contains green features such as:

Sustainable Site Design• Downtown location is close to many community amenities including a skybridge to the adjacent Spokane Convention Center.• Urban Landscape design features native and water-wise plants.• Rainwater from the roof is stored and used to water the landscaping.• Easy walking distance to 6 bus lines serving two stops.• Bike secure racks, lockers and showers to encourage arrival by bike.• Guests are allowed to take their bikes to their rooms if desired.• 75% of parking is underground or in a parking structure.

Water Efficiency• Water-thrifty plants and efficient irrigation systems uses no potable water. • Efficient low flow and flush plumbing fixtures will reduce potable water use by 20% while still meeting guest expectations for performance. • Recirculation systems make hot water immediately available to guest rooms.

Energy EfficiencyEnergy-efficient strategies earned 7 points for energy savings in the LEED program. The design is expected to save, 24.5% in energy use and 28.5% in utility costs ($320,757 per year) compared to standard practice design. The reduction in energy use is equivalent to powering 64 homes for one year and avoids CO2 emissions equivalent to planting 25,344 trees. Components of the efficient design include:

• R-30 wall insulation, advanced sealing, Solarban 70xl high performance windows.• Natural daylight for guest rooms and key public spaces.• Daylight controls and occupancy sensors dim electric lights.• Efficient interior and exterior lighting and controls.• High-efficiency condensing boilers, and efficient chillers, fans, and pumps.• Efficient demand-controlled mechanical system.• Heat reclaim systems for walk-in cooler systems.• State of the art laundry and kitchen equipment reduces energy and water use.

Designed and constructed to meet the Silver level certificationin the LEED® for New Construction program

Recycled Materials Over 12% of the cost of site, structural and architectural materials contain recycled content. Post consumer content comes from material used by people and recycled into a new product like those below. Pre consumer content comes from material diverted during the manufacturing process. Examples of recycled materials included in the project are:

• Steel structure: 46% post consumer, 16% pre consumer• Rebar: 87% post consumer, 13% pre consumer• Roofing: 15% pre consumer• Aluminum Storefront and Curtainwall: 25% post consumer• Acoustical Ceiling Tile: 77% pre consumer• Carpet tile: 12% post consumer, 36% pre consumer• Drywall: 61% pre consumer• Steel Studs: 24% post consumer, 9% pre consumer• Insulation: 15% pre consumer

Indoor Environmental Quality The Davenport Grand Hotel is dedicated to health and well being of Hotel guests, visitors and staff. The building design supports this goal with features such as:

• Abundant outside air ventilation exceeds code minimum requirements. • High efficiency air filters remove pollen and other particulates from supply air. • Composite wood doors, MDF and particleboard contain no added urea formaldehyde. • Adhesives, sealants, paints and coatings contain zero or very low VOC (volatile organic compounds). • Carpets meet the Green Label Plus program of the Carpet & Rug Institute. • The contractor followed LEED requirements to protect indoor air quality during construction and prior to turning the project over for public use.• The Hotel uses a comprehensive Green Cleaning Plan that requires GreenSeal and Environmental Choice-compliant products and equipment.

Regional Materials Over 45% of the cost of site, structural and architectural materials contain regional components. Examples of materials manufactured as well as extracted or harvested or recovered with a 500 mile radius of the project are:

• Pre-cast Concrete • Cast-in-Place Concrete• Masonry• Steel Studs • Structural fill and base courses• Sidewalks

About LEED®

Leadership in Energy and Environmental Design (LEED) is an internationally recognized green building certification system that measures how well a building performs across all the metrics that matter most: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.

Developed by the U.S. Green Building Council (USGBC), LEED provides building owners and operators a concise framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions. LEED is flexible enough to apply to all building types. It works throughout the building life cycle – design and construction, operations and maintenance, tenant fit out, and significant retrofit.
