Bremerton, WA 9,270 sq. meters8-story building

Integrated energy efficiency strategies are expected to reduce the building energy use by approximately 34% compared to the national ASHRAE 90.1-1999 standard. Some of the energy efficiency strategies include high-efficiency motors for all fans and pumps that provide at least 3.0 horsepower and variable-speed drives on the secondary chilled water pumps. Domestic hot water is provide with semi-instantaneous water heaters, which use steam to heat water in small storage tanks located near the points of end use—these are expected to reduce energy costs by 15%.

Green Strategies

Water Heaters

Use demand water heaters

Cooling Systems

Commission the HVAC system

HVAC Distribution Systems

Use high-efficiency pumps and motors

HVAC Controls and Zoning

Use direct digital control (DDC) systems

 

Design for Adaptability to Future Uses

Four-person living units were designed to facilitate possible conversion into smaller one- or two-person units. Dual temperature sensors on the fan coil units also facilitate this conversion.

Green Strategies

Protection of Global Ecosystem

Minimize ozone-depletion potential of refrigerants in cooling systems

Design for Materials Use Reduction

Cluster buildings to minimize infrastructure requirements

Plan for Materials Longevity

Use materials and systems with low maintenance requirements

Job Site Recycling

Use reusable forms

Require a waste management plan from the contractor

Recycling by Occupants

Design a physical in-house recycling system

Pre-Consumer Recycled Materials

Use recycled materials as aggregate in the concrete

Materials and Wildlife Habitat

Use wood products from independently certified, well-managed forests for finish carpentry

Transportation of Materials

Prefer materials that are sourced and manufactured within the local area

Water Conservation and Use

In addition to the reduction and treatment of stormwater flows, Building 1044 features water-efficient landscaping that requires no permanent irrigation system. Artificial turf in the high-use recreation areas, such as the horseshoe pit, eliminates the need for maintenance and water use in those areas.

Outdoor potable water use: 0 gal/yr (0 liters/yr)

Green Strategies

Runoff Reduction

Reduce driveway pavement

Consider porous turf-paving systems on low-traffic parking and driveway areas

Managing Stormwater

Incorporate a pollutant separation/filtering system in parking lot drains

Demand for Irrigation

Utilize non-plant landscaping

Irrigation Systems

Use water-efficient irrigation fixtures

Low-Impact Siting

Select building sites that make use of existing infrastructure
