“…an efficiency is assumed for the gas boiler that refers to the efficiency of condensing boilers, while for the oil boiler a lower efficiency is considered that is related to older boiler technologies. [95,99] The comfort temperature inside the buildings is assumed to have a value of 21C for when occupants are active at home. The night reduction temperature is set for all buildings to 18C.…”

The installation and operation distributed energy resources (DER) and the electrification of the heat supply significantly changes the interaction of the residential building stock with the grid infrastructure. Evaluating the mass deployment of DER at the national level would require analyzing millions of individual buildings, entailing significant computational burden.To overcome this, this work proposes a novel bottom-up model that consists of an aggregation algorithm to create a spatially distributed set of typical residential buildings from census data. Each typical building is then optimized with a Mixed-Integer Linear Program to derive its cost optimal technology adoption and operation, determining its changing grid load in future scenarios.The model is validated for Germany, with 200 typical buildings considered to sufficiently represent the diversity of the residential building stock. In a future scenario for 2050, photovoltaic and heat pumps are predicted to be the most economically and ecologically robust supply solutions for the different building types. Nevertheless, their electricity generation and demand temporally do not match, resulting in a doubling of the peak electricity grid load in the rural areas during the winter. The urban areas can compensate this with efficient co-generation units, which are not cost-efficient in the rural areas.

“…Requirements for and uses of public and private spaces do change with age as individuals transition out of raising children and structuring their daily activities around their professional lives, as they face higher risks of declining health and become less mobile, and as growing numbers of them will be living alone (Olsberg, 2012, pp. 143e149).…”

“…For example, while the generation of the Great Depression in North America and of WWII Europe experienced hardship and curtailed their consumption during the early years of reconstruction, with savings rates and investments in infrastructure high, the subsequent baby boom generation, which now constitutes a major part of demographic change in North America and Europe, has seen a near steady expansion of personal consumption during their lifetime (Franklin & Ruth, 2011). Both experiences brought, and continue to bring, with them drastically different consumption behaviors and mobility patterns during later parts of their lives, and different perspectives on the adequacy of urban infrastructure systems and services, local environmental quality and amenities, social networks, personal independence, and feelings of safety and belonging – all of which shape how livability is conceptualized (Olsberg, 2012, pp. 143e149).…”

Livability for all? Conceptual limits and practical implications

Livability has risen, alongside sustainability, as a guiding principle for planning and policy. Promoted as the more tangible of the two concepts, livability shapes public perception and infrastructure investments in cities, as well as competition among cities for the attention of the public, investment communities, and potentially fickle and mobile human capital. This paper takes stock of the current discourse on livability, identifies two central elements that have yet to shape the assessments of livability and policies to promote it, and explores strategies for research and practice to transform the livability concept, and with it the places in which the lives and livelihoods of people unfold.

“…It is widely agreed that both user-centered design (UCD) and participatory design (PD) are meaningful approaches when designing AAL solutions, and their importance is shown in a variety of different studies, despite failing to prevail in technological developments [18,20,21]. This issue also seems to contribute to a well-identified challenge in the uptake of AAL solutions by end users [18,22,23], paired with the low level of general public awareness of AAL solutions [22][23][24].…”

A Multipurpose Platform for Ambient Assisted Living (ActiveAdvice): Usability Study

Background: Aging of the global population is slowly paving the way for new markets for care products and services. The desire of older people to maintain their independence while remaining at home is boosting the development of ambient assisted living (AAL) solutions. Lack of user awareness of AAL solutions paired with an insufficient use of user-centered and participatory design approaches in the development of these products has hindered the uptake of these solutions by end users. Objective: This study aims to describe the usability and users' experiences within a novel platform, ActiveAdvice, aimed at offering advice and a holistic market overview of AAL products and services. Methods: Usability tests were performed on the developed platform among identified prospective end users, with 32 older adults and informal carers from 4 European countries being part of the user tests. The usability and appeal of the web interface design, information flow, and information architecture were analyzed by collecting both objective and subjective measures. These would include pretest and posttest surveys, along with a series of think-aloud tasks to be performed within the platform. Results: The outcomes suggest that the ActiveAdvice platform's objectives and functionalities are mostly aligned with the needs and expectations of end users, who demonstrated interest in using it, stressing its purpose along with its simple and intuitive interaction. Task completion rates were high, and participants had good satisfaction rates when navigating the platform. However, the tests still advocate for an improved design at some points and better disclosure of information. Conclusions: Our findings shed light on a few peculiarities of interface design, information architecture, user needs, and preferred functionalities, which should be applied to future developments of similar platforms with related services. The AAL field could benefit from tools supporting the dissemination of available AAL solutions and how they can improve one's quality of life. These tools may benefit not only older adults but also caregivers, business owners, and governmental employees.
