The San Mateo County Sheriff's Forensic Laboratory and Coroner's Office is a highly secure and technologically innovative laboratory facility designed to provide a superior workplace, flexibility to accommodate changing needs over time, and advanced

approaches to resource efficiency. The facility houses several key public safety and essential public service functions, including 911 dispatch, emergency-operations center, sheriff's training facility, forensics laboratory, and the coroner's office. The facility combines the various agencies into one essential structure that must remain functional after a major earthquake, thereby minimizing the risk of disruption of services. The orientation of the building, large roof overhangs, north-facing clerestory windows, and canted windows on the southwest reduce glare while maximizing daylight. Energy usage has been reduced by more than 50 percent relative to the stringent California Title 24 energy requirements, and renewable energy systems supply all non-HVAC energy requirements.

Twenty-six thousand square feet of rooftop-mounted photovoltaic panels will produce enough power to accommodate all of the building's non-HVAC electrical requirements.

Twenty-six thousand square feet of rooftop-mounted photovoltaic panels will produce enough power to accommodate all of the building's non-HVAC electrical requirements. The photovoltaic roof generates more than 180 kilowatts of electricity, over half of the summertime peak load. During off-peak daylight hours this facility exports energy to other buildings in San Mateo County. Assuming energy cost savings estimated at about $70,000 per year, the installation has a simple payback period of about ten years.

Jury Comments: "The San Mateo County Forensics Laboratory is a tour de force in photovoltaic power generation that meets more than half of the peak summer electrical load, while water conservation strategies for site and building reduce water use by over 40 percent. This building devotes its entire 26,000-square-foot roof area to the harvesting of sunlight, meeting more than 28 percent of total energy demands."

2003 AIA/COTE Top Ten Winner STEINHUDE SEA RECREATION FACILITY LOCATION: Steinhude, Germany ARCHITECT: Randall Stout Architects

This project was conceived as an amenity to EXPO 2000 visitors to the rural region of the Steinhude Sea, north of Hannover, Germany. The theme for EXPO 2000, "Man, Nature, Environment," led to the goal of an artistically intriguing structure that was fully self-sustaining with minimal impact on the surrounding ecosystem. This small recreation facility is located on an island at the south shore of the Steinhude Sea. The island ecosystem consists of a beach area, green fields, nature walk, children's play area, and a bird sanctuary. The new 3,057-square-foot facility accommodates, with minimal ecological impact, a café, lifeguard facilities, boathouse, storage, public toilets and showers, and an exhibition area and observation deck. Prefabrication of the building in a nearby factory resulted in waste minimization and ecosystem protection. The ecologically sensitive island would have been damaged by heavy construction equipment, so building components were panelized off-site, test-assembled, delivered to the sea dock, loaded onto barges, and floated to the island's edge, where a barge-mounted crane placed the panels.

Energy self-sufficiency is achieved via photovoltaic panels, solar hot-water collectors, seed-oil-fueled cogeneration microturbine, daylighting, natural ventilation, passive solar, building automation, and high-performance materials. These systems provide complete lighting and power needs for the building, recharge for a fleet of eight photovoltaic-powered boats, and also produce excess electricity to sell back to the utility grid. Other sustainability practices are incorporated, such as gray-water and harvested-water systems, green materials, and waste reduction. Integration of solar and renewable ideas, from conceptual design to partnering with the local utility company and a technically savvy contractor, has led to a building that is a joy to its users.

Jury Comments: "The Steinhude Sea Recreation Facility on an island on the northern German coast is a visually powerful and compelling expression of sustain-ability. With photovoltaic, solar hot water, daylighting, renewable-source power generation, and a gray-water system utilizing rainwater collected from the roof and landscaped terraces, this prefabricated building uses no fossil fuels, eliminating all greenhouse gas emissions."

2003 AIA/COTE Top Ten Winner WINE CREEK ROAD HOME LOCATION: Healdsburg, California ARCHITECT: Siegel & Strain Architects

This modest family retreat in northern California was conceived of as a single gable that spans enclosed living and sleeping areas separated by an open breezeway, or dogtrot. The form and construction of the house reflects the spirit of local vernacular buildings, taking maximum advantage of the site and climate to make the house comfortable while minimizing energy use and environmental impacts. The chief strategy for saving energy was to keep the building cool during the long, hot summers without mechanical cooling, which was accomplished by employing natural ventilation, thermal mass, and superior insulation. The thin building section, the dogtrot, and the placement of windows optimize opportunities for natural ventilation. The interior plaster walls and concrete floor provide enough thermal mass to minimize temperature swings and integrate well with the radiant-heating system. Opening the windows at night cools the house enough that it remains cool through the hottest part of the day. A high-efficiency water heater provides radiant floor heating. These measures resulted in a design that exceeds California's strict energy-efficiency standards by 29 percent and keeps the building cool except for the hottest hours of the hottest days. The owners chose high-efficiency, low-water-use appliances.

Jury Comments: "This modest home in northern California is a basic, highperformance, low-tech building in the spirit of traditional Japanese residential architecture. This simple retreat uses natural ventilation rather than mechanical cooling, thermal mass, radiant floor heating, straw-bale construction, and on-site management of almost all stormwater."

At the Wine Creek Road Home, the design of the Wine Creek Road Home reflects the spirit of local vernacular buildings, taking maximum advantage of the site and climate to make the house comfortable while minimizing energy use and environmental impacts.

Summer comfort without mechanical cooling was accomplished by employing natural ventilation, thermal mass, and superior insulation.

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
