“…Finally following the literature review on data for the impact of the sensors, these were found to have a negligible impact when looking at solely the in-use phase for the type of sensors used in the fridge. The studies used to come to this conclusion were those by Bonvoisin et al (2012Bonvoisin et al ( , 2014Bonvoisin et al ( and 2011 and Louis et al, 2015).…”

This paper shows how designers of IoT-enabled products can assess the environmental impacts associated with the user behaviour and the service system around the product. High-quality secondary data and a user-behaviour survey were able to highlight critical aspects of a smart fridge's design. A streamlined LCA looked at just the in-use phase of the product within 4 PSS scenarios. The system included: the effects on the food waste; grocery shopping methods; fridge door openings; and how the users interact with the smart fridge features. The results show that a smart fridge as within a PSS can reduce the impact on the environment (GWP of 21,700 kg CO2-eq within the ‘average PSS scenario’ and GWP of 23,100 kg CO2-eq for the normal fridge with ‘typical scenario’). The product's increased emissions are counteracted by the reduction in GWP due to: reduction in food waste; and shifts from brick-and-mortar grocery shopping to e-commerce. Therefore some of the critical aspects of the product's design that are most influential on the environmental impact of an IoT fridge are: the design of the web-browsing capability; and the use-by date tracking system.

“…It has been previously highlighted that expectations on smart homes lie in the reduction of energy consumption and decrease in related to the energy consumption [2]. Our earlier research indicated that the economic and CO 2 savings achieved through these smart devices do not necessarily compensate for the investment, especially in terms of energy savings vs. energy consumption of control devices [3]. This research looks at the trade-off between technology deployment and enviro-economic benefits of home automation.…”

Abstract-Smart grids are meant to reach multiple goals such as leveling the electricity demand profile, reducing electricity consumption and increasing the energy efficiency of the electrical grid. Smart buildings play an important role in achieving these goals. With an increased number of measuring and controlling tools, new problems also arise, such as their economic and environmental impacts, juxtaposed to the levels of savings achieved by them. This research investigated the impact of home automation on electricity consumption, related CO 2 emissions and costs. A smart building model with its appliances and different number of inhabitants was used along with eight electricity contracts and four different technology systems deployed. The results showed that a fully deployed automation system may be counterproductive, as the electricity need of the system may exceed the savings achieved by it. Therefore, a careful selection of the appliances to be used should be performed.

“…The aim of [15] is to minimize operational energy cost for households through load shifting to maximize renewable energy power produced. A life cycle assessment was conducted by [16] where the environmental impact of HEMs in terms of their potential benefits and detrimental impacts was evaluated. A negative energy payback time was computed for home automation devices due to the energy consumption of smart plugs.…”

This research paper presents the development of a biased load manager home energy management system for low-cost residential building occupants. As a smart grid framework, the proposed load manager coordinates the operation of the inverter system of a low cost residential apartment consisting of rooftop solar photovoltaic panels, converter and battery, and provides a platform for discriminating residential loads into on-grid and off-grid supply classes while maximizing solar irradiance for optimum battery charging and improving consumer comfort from base levels. Modelled in a Matlab simulation environment, the system incorporates a converter system for maximum power point tracking using a hopping algorithm, with a dedicated mechanism for smart dispatch of specified loads to meet the users' comfort based on the priority ranking of the loads. Results obtained indicate a 34% reduction in electricity cost, 26% reduction in carbon emissions and a 4% increase in comfort level for the photovoltaic/battery/utility option compared to the utility only option. The results further show that cost is a major factor affecting the users' comfort and not necessarily dispatch of appliances to meet energy needs. The research can be useful for encouraging the adoption of the photovoltaic/battery/utility option by low/middle income energy users in developing countries.
