Residential buildings in Greece constitute an important portion of the existing building stock. Furthermore, most of these buildings were built prior to the first Thermal Insulation Code of 1981. The article focuses on existing, typical residences built after 1920, which are found mostly in suburban areas and settlements all around Greece. The purpose of the research is to evaluate the effect of simple bioclimatic interventions focused on the improvement of their diurnal, inter-seasonal and annual thermal performance.

The applied strategies include application of thermal insulation in the building shell and openings, passive solar systems for the heating period and shading and natural ventilation for the summer period. The effect of the strategies is analysed with the use of building energy analysis. The simulation method was selected because it provides the possibility of parametric analysis and comparisons for different proposals in different orientations.

The results show that the increased thermal mass of the construction is the most decisive parameter of the thermal behaviour throughout the year.

The typical residences under investigation are often found in urban and/or suburban surroundings. These mostly refer to free-standing buildings situated, which, in many cases, do not have the disadvantages and limitations that the geometrical characteristics of densely built urban locations impose on incident solar radiation (e.g. overshadowing during the winter) and air circulation (e.g. reduce natural ventilation during the summer). Nevertheless, even in these cases, the surrounding built environment may also have relevant negative effects, which were not taken under consideration and could be included in further, future research that will include the effect of various orientations, as well as of neighbouring buildings.

Existing residences built prior to the first Thermal Insulation Code (1981) form an important part of the building stock. Consequently their energy upgrade could contribute to significant conventional energy savings for heating and cooling, along with the inter-seasonal improvement of interior thermal comfort conditions.

The proposed interventions can improve thermal comfort conditions and lead to a reduction of energy consumption for heating and cooling, which is an important step against energy poverty and the on-going energy crisis.

The proposed interventions only involve the building envelope and are simple with relatively low cost.

This chapter presents an international review of the experiences of children and parents regarding care during the COVID-19 pandemic. The pandemic profoundly impacted children and families, magnifying the influence of governmental policies, socio-economic disparities and cultural contexts on children's experiences and exacerbating global inequalities. Vulnerable families faced increased challenges affecting children's rights and well-being, while the transition to digital learning highlighted the critical need for equitable access to technology. Despite extensive documentation of these challenges, research focusing on the pandemic's impact on young children's development, well-being, socialization and learning opportunities, as well as the experiences of parents/carers, remains limited. This scarcity stems from the pandemic's constraints on research activities, requiring reliance on online methods and the increased burdens on parents/carers, making participation in research more challenging.

Employing the PRISMA 2020 method for a literature review, this chapter aggregates international research findings on the subject, examining the impacts of COVID-19 on health and well-being, knowledge of the pandemic, effects on learning, educational strategies, online activity engagement and collaboration with Early Childhood Education and Care (ECEC) services. It concludes with a synthesis of insights and recommendations drawn from the reviewed literature.

The chapter contributes to a comprehensive framework for understanding the pandemic's impact on young children and their families, emphasising the importance of targeted interventions, equitable resource distribution and ongoing support for the ECEC sector to address the challenges and opportunities presented by the COVID-19 pandemic and future crises.
