Integrating Smart Ceiling Fans and Communicating Thermostats to Provide Energy-Efficient Comfort

The project goal was to identify and test the integration of smart ceiling fans and communicating thermostats. These highly efficient ceiling fans use as much power as an LED light bulb and have onboard temperature and occupancy sensors for automatic operationbased on space conditions. The Center for the Environment (CBE) at UC Berkeley led the research team including TRC, Association for Energy Affordability (AEA), and Big Ass Fans (BAF). The research team conducted laboratory tests, installed99 ceiling fans and 12 thermostats in four affordable multifamily housing sites in California’s Central Valley, interviewed stakeholders to develop a case study, developed an online design tool and design guide, outlined codes and standards outreach, and published several papers.The project team raised indoor cooling temperature setpoints and used ceiling fans as the first stage of cooling; this sequencing of ceiling fans and air conditioningreducesenergy consumption, especially during peak periods, while providing thermal comfort.The field demonstration resulted in 39% measured compressor energy savings during the April–October cooling seasoncompared to baseline conditions, normalized for floor area. Weather-normalized energy use varied from a 36% increase to 71% savings, withmedian savings of 15%.This variability reflects the diversity in buildings, mechanical systems, prior operation settings, space types, andoccupants’ schedules,preferences, and motivations. All commercial spaces with regular occupancy schedules (and twoof the irregularly-occupied commercial spaces and one of the homes) showed energy savings on an absolute basis before normalizing for warmer intervention temperatures,and 10 of 13 sites showed energy savings on a weather-normalized basis. The ceiling fans provided cooling for one site for months during hot weather when the coolingequipment failed.Occupants reported high satisfaction with the ceiling fans and improved thermal comfort. This technology can apply to new and retrofit residential and commercial buildings

Marketing electronic resources to distance students: A multipronged approach

When students are surveyed regarding their expectations and satisfaction with library services, it is common to receive suggestions for services or guides the library might offer. In many cases these suggested services already exist. This has been shown to be true in surveys of distance students at the University of New England, Armidale, New South Wales, Australia (UNE). Distance students' varying, and often limited, knowledge of what their home institution offers, coupled with low expectations and remoteness from the physical library pose particular challenges for librarians. What is involved in effectively marketing electronic resources to distance students? How can students be made aware of the wealth of resources available? How can they be helped to achieve proficiency in their use? What initiatives result in increased usage? In seeking to answer these questions, this chapter advocates presenting relevant quality resources which are accessible any time/anywhere. It also affirms offering support at the students' point of need. The value of incorporating into the academic curriculum a requirement to utilize electronic resources is highlighted. The final section examines the effectiveness of a range of standalone approaches which may be used to promote resources

Getting Grandma Online: Are Tablets the Answer for Increasing Digital Inclusion for Older Adults in the US?

Using information and communication technologies (ICTs) can improve older adults\u27 quality of life. ICT use is associated with decreased feelings of loneliness and depression, along with increased feelings of independence and personal growth. However, limited access and low technological self-efficacy are key reasons why some groups, especially older adults, are excluded from being fully engaged in the digital world. In this study, we focus on older adults\u27 technological self-efficacy, which is related to their actual use of technology and the second level digital divide. Specifically, we examine: (a) how older adults decide to use a new technology, tablet computers; (b) how they conquer the barrier of technological self-efficacy through using tablets; and (c) the impacts of using this new technology in their lives. Twenty-one in-depth interviews were conducted with older adults residing in independent living communities in a medium-sized city in the Deep South region of the United States. Observational and enactive learning played important roles for older adults in using tablets. Seeing others use tablets, getting recommendations from family members, or having tablets given to them were the primary reasons they started to use tablet computers. The ease of use feature of tablets helped solve the problem of lacking technological self-efficacy. Using tablets helped increase a sense of connectedness. Tablet computers may be one way to increase digital inclusion among older adults
