Summary: This study investigates the feasibility of the Photovoltaic-Diesel Hybrid system for rural electrification in sub-Sahara Africa using a case study of Chilubi island, Zambia. By considering different hybrid system configurations and the rate of access to electricity, the study identifies the most viable technical solutions based on the least Levelized Cost of Energy (LCoE) and life cycle costs. The results demonstrate that standalone diesel generators are not economically sustainable, and a 100% photovoltaic (PV) system with a battery has the lowest LCoE. However, the initial capital cost of solar energy projects in Zambia is higher compared to diesel-based plants.

Summary: Energy storage is crucial for unlocking the potential of renewable generation and reducing peak power demand. An energy management strategy presented in the study can reduce peak power drawn from the grid by a community of 60 homes by an average of around 30%. While photovoltaic generation significantly reduces greenhouse gas emissions, community energy storage in batteries is effective at reducing peak demand but comes with significant costs and potential increases in emissions. Future cost projections show potential for considerable reductions in the cost of community electricity generation and storage.

Summary: Outdoor thermal comfort has significant impacts on the health and well-being of different population groups, with older people being particularly vulnerable. However, there is a lack of research on outdoor thermal comfort for older individuals compared to indoor environments. This paper provides a comprehensive literature review on the differences in thermal sensations and preferences between older people and other age groups, as well as the parameters that should be considered in the planning of outdoor spaces. The existing comfort models do not fully capture the effects of both environmental and human-based parameters for assessing outdoor thermal comfort for older people.
