Centro de Documentación de Fundación MAPFRE - Facilitating energy savings with programmable thermostats : evaluation and guidelines for the thermostat user interface

Notas: Sumario: Thermostats control heating and cooling in homes representing a major part of domestic energy use yet, poor ergonomics of these devices has thwarted efforts to reduce energy consumption. Theoretically, programmable thermostats can reduce energy by 515%, but in practice little to no savings compared to manual thermostats are found. Several studies have found that programmable thermostats are not installed properly, are generally misunderstood and have poor usability. After conducting a usability study of programmable thermostats, we reviewed several guidelines from ergonomics, general device usability, computerhuman interfaces and building control sources. We analysed the characteristics of thermostats that enabled or hindered successfully completing tasks and in a timely manner. Subjects had higher success rates with thermostat displays with positive examples of guidelines, such as visibility of possible actions, consistency and standards, and feedback. We suggested other guidelines that seemed missing, such as navigation cues, clear hierarchy and simple decision paths.Registros relacionados: En: Ergonomics : the international journal of research and practice in human factors and ergonomics. - Oxon [United Kingdom] : Taylor & Francis, 2010- = ISSN 0014-0139. - 04/03/2013 Volumen 56 Número 3 - marzo 2013 , p. 463-479Outras classificações: 875
