UK STUDY LINKS PRODUCTIVITY TO VENTILATION SYSTEMS
An analysis of occupant surveys from nearly 20 years of building investigations suggests that comfort and perceived productivity are greater in buildings where occupants have more control over their environment. The study, based on data generated by the UK's PROBE research project and the firm Building Use Studies, with funding from the Department of the Environment Transport and the Regions, looks at comfort and productivity in buildings with four ventilation types--naturally ventilated, air conditioned, mixed mode and advanced naturally ventilated. Occupants' perceived productivity is related to the building's overall comfort score, which is an average of seven variables--summer and winter temperature, summer and winter air quality, lighting, noise, and overall comfort. Occupants in mixed-mode buildings, in which they can opt for natural ventilation or air conditioning, reported better than average perceived productivity. Unless conditions are exceptionally hot and humid, occupants generally prefer natural ventilation, especially if they have access to operable windows. Occupants in advanced naturally ventilated buildings, which have sophisticated controls to optimize building performance, reported relatively poor productivity. The buildings that perform best in terms of occupant comfort and perceived productivity are those with a high level of individual control or with a facility management so highly responsive that the occupants never experience discomfort in the first place.

"SERVICIZING" MAY BENEFIT ENVIRONMENT, BOTTOM LINE
A growing number of manufacturers are shifting their focus to the services their products deliver instead of the physical products themselves, according to a new report from the Tellus Institute, a Boston-based nonprofit research and consulting group. This "servicizing" of industry, says Tellus, may be a significant driver toward extended product responsibility, the principle that companies share responsibility for a product's environmental impacts along its entire life-cycle, including its sourcing, manufacturing, use, and disposal. But the underlying reasons for servicizing have less to do with environmental stewardship than with other business strategies--it is "one aspect of a major shift in how firms think about and approach competitiveness," says Tellus. The report examines the servicizing efforts of seven companies, including furniture maker Herman Miller's subsidiary, Coro, Inc., which provides large corporate buyers with move and reorganization services. The company is the only furniture maker to have post-occupancy support as an integral part of its business strategy. With its reverse-logistics system, including product take-backs and trade-ins, Coro hopes to position its service as an environmentally responsible alternative to typical disposal methods, which often include landfilling. Servicizing doesn't automatically lead to environmental gains in product design and manufacturing methods, however, if a company doesn't have a mechanism for service activities to influence design and manufacturing activities. Other impediments to servicizing include the complexity of life-cycle design, the need for a closer seller-buyer relationship, and tax policies such as those favoring equipment ownership over leasing.

SPRAWL SUBJECT OF TWO REPORTS
Business and government leaders are increasingly concerned about the economic, social, and environmental impacts of urban sprawl, say two new reports. A study by the National Association of Local Government Environmental Professionals profiles the responses of 19 companies and business coalitions to sprawl, and catalogues the institutional barriers, tax policies, and local and federal government regulations that must be overcome if "smart growth" practices are to become widespread. "Some American business leaders are beginning to recognize that sprawl can raise the cost of doing business and reduce long-term profitability," says the report. NALGEP defines sprawl as "low-density, discontinuous, automobile-dependent, new development on the fringe of settled areas, often surrounding a deteriorating city or town core." Some businesses are taking steps toward "smart growth" by finding "ways to grow while respecting and enhancing the communities they call home," says the NALGEP's report. Quality of life, these business leaders recognize, directly affects economic prosperity, and sprawl threatens the quality of life in many communities. And in a survey conducted for the American Institute of Architects, 68 percent of state and local government executives and policymakers said they believe concern over "livable communities" is growing. Nearly two-thirds said they were involved in initiatives that address ways to solve quality-of-life issues such as traffic, urban sprawl, and preservation of open space.

SAN FRANCISCO ADOPTS GREEN BUILDING ORDINANCE
In July, the City of San Francisco became one of the nation's first municipalities to adopt a green building ordinance for City-owned projects. The additions to the San Francisco Municipal Code, known as the Resource Efficient Building Ordinance, consist of two distinct parts. The first part specifies a few requirements for water conservation, energy-efficient lighting, indoor air quality, and recycling. The second part requires the City to designate a number of pilot green building projects that will demonstrate innovative designs and materials. Each of these projects will be evaluated after construction, and their performance reported to the City's Board of Supervisors.

ELEVATOR TECHNOLOGY PROMISES ENERGY SAVINGS
In 1998 Montgomery KONE introduced an elevator technology to the U S market that may provide significant energy savings over competing systems used in low- and mid-rise buildings. The EcoSystem elevator is driven by a thin permanent magnet motor mounted directly to the hoisting rail. This drive system is about 40 percent more efficient than overhead traction elevators typically used in mid-rise applications-even those with variable speed drives-and 60 percent more efficient than hydraulic elevators often used in low-rise buildings. In addition to saving energy, this efficiency may translate into reduced sizing requirements for electrical service and emergency back-up systems. Also, with EcoSystem and other non-hydraulic elevators, there is no risk of hydraulic fluid leaking and contaminating groundwater. The EcoSystem model that is currently available is relatively small, with a 2,500 pound maximum capacity and top speed of 200 feet per minute. It can handle up to 10 landings and 80 feet of vertical travel. Later this year Montgomery KONE plans to introduce a larger, faster version of the EcoSystem, capable of carrying 4,000 pounds and serving up to 24 landings.

U S DEPARTMENT OF ENERGY http://www.eren.doe.gov/buildings The U S Department of Energy's Office of Building Technology, State and Community Programs (BTS) has announced that compact fluorescent lamps will now wear the Energy Star label, the national symbol of energy efficiency. Energy Star light bulbs represent the cutting edge in lighting technology and enable homeowners, schools, and businesses to reduce electricity use, promote energy efficiency, and save money. Energy Star lights have a minimum lifetime of 6,000 hours, do not need to warm up, and come in a wide range of styles, shapes, and wattage values. By replacing five of its most used incandescent lights with Energy Star bulbs, a household in the U S could save up to $235 in lighting energy costs over the life of the bulbs. For more information on BTS' programs to reduce building energy use, please see DOE's Energy Efficiency and Renewable Energy Network website <http://www.eren.doe.gov/buildings> or call 800.363.3732.
