             Selectivity

             Automation is not an all or nothing choice and the ability to selectively enable or disable
             automation, either centrally or on a room-by-room basis, has a number of benefits.
                A disabled individual who wishes to maximise their own functional ability may still
             require the support of automation if, for example, their performance levels diminish
             throughout the day. Their performance levels may be unpredictable and fluctuate, or their
             cognitive performance may vary, leading to alteration in cognitive load associated with
             psychomotor skills (Rotstein et al., 2012; Wolkorte et al., 2015). Being able to selectively
             enable automation within the living space will help maintain their sense of control and
             empowerment in the face of unpredictable circumstances. Data on the patterns of how
             such options are used also has the potential to provide useful information in relation to
             the trends in the individual’s functional status.
                Consider a living space that is shared by residents who have differing personal require-
             ments, e.g., a mix of ambulant and wheelchair-bound residents. In this situation, more
             relevant still is the shared use of a living space by a physically disabled individual and their
             carer and/or family. Some aspects of automation such as lighting may have a common
             benefit and preference, but performance of automated door openers is a clear area of pos-
             sible conflict. It is not uncommon to find door openers in such environments turned off or
             jammed open, with the loss of privacy and control that this can bring for the intended user.
                Scene setting to establish a number of combinations of automated response is an effec-
             tive approach to managing these types of issues, and an intelligent system provides the
             necessary ease of programming and level of control of such options to meet the above
             concerns. Scene setting should not be confused with macro functions in environmental
             control systems, which lack the feedback mechanism to ensure that scenes are safely and
             effectively managed.
                ‘Green’ issues have risen significantly up the political agenda in recent years and energy
             management is becoming more of a central focus for the development and of smart house
             technologies (Lobaccaro et al., 2016). At a very local level the technologies that are being
             considered can be used to support this agenda, i.e., efficient use of lighting, heating and
             electrical appliances and de-energising devices during nonoccupancy. These technolo-
             gies also offer advantages in terms of connectivity with smart metering systems and wider
             energy management strategies, providing the opportunity for a detailed understanding of
             local energy usage and supporting programming to automatically adjust devices based
             on use of the living space. These benefits have in the past opened up access to govern-
             ment funding initiatives related to energy policy, as in the case of the Ayrshire Housing
             Association project (Clarke et al., 2008). It also has the important additional local benefit
             of reducing utility bills for individuals who are already generally financially disadvantaged
             within society. There are an increasing number of devices available for the domestic mar-
             ket that can monitor and control energy usage, such as smart plugs and heating controllers
             such as Nest, but beyond the availability of control and monitoring via smartphones it is not
             clear how integration into the holistic management of an environment would be achieved.
             There is a national programme to install smart meters to allow occupants to monitor their
