The Southeast Tunisian cave dwellings of Matmata are a well-known historical model which amazingly adapt with cultural, environmental and climatic features of its surrounding. Many studies have discussed the sustainability of these dwellings but none has thoroughly discussed its performance on light of health and wellbeing of its dwellers. The WELL_V1 rating system, established in 2016, is a first of a kind certification system that solely focus on the health performance of the built environment. It gives credit to designs that enhance and promote physical and psychological health of the users. The study examines the health performance of Matmata cave dwellings in the light of WELL_V1 recommendations and features. The study revealed that these subterranean historical dwellings have proven good performance in relation to daylight saturation, indoor thermal relief, solar glare control, physical activity enhancement, exterior noise reduction, biophilic design and cultural enrichment. On the other hand, they lack sufficient performance in relation to air purification, social interaction, clean water supply, and altruism encouragement. Considering the scientific background, materials and technologies available for those who designed and built these dwellings, the health-related performance of their work seems unique and impressive.

There is no doubt that there is a close relationship between health problems and housing conditions. According to the World Health Organization (WHO) estimates in developing countries those 2 million early and unexpected deaths, with close to half occurring among children less than 5 years old die from indoor air pollution and bad housing. Housing is an important determinant of health, and substandard housing is a major public health issue. Designing and bad orientation of housing are found to have significant effects on poor respiratory health especially in children, and increase an infectious disease thereby putting them at higher risk of life-threatening diseases. The rate of spreading the diseases among children is increasing in developing countries in last years which form serious threats to public health and natural growth of children and inturn reflect on average of long life especially in Poor Urban Region and low socio-economic families. The research examined the relationship between housing and health using longitudinal data collecting and analyzing data from Chest Hospital records and giving a questionnaire to inhabitants who suffered from respiratory illness as a result of bad design and inadequate orientation…etc. For many children this means losing sleep, restricted physical activity, slow growth, and missing school. The research submits a criterion to redesign public housing especially the low incoming housing and employ the internal and external determinants as ventilation rates, percentages of voids, orientation, finishing materials and physical infrastructure…. etc. and many other factors which affect public health to improve environmental quality, assessing housing conditions and affordable housing. Now, it is the time to create healthier homes by confronting substandard housing for creating a healthy generation.

Archaeological sites in coastal regions have suffered from many forms of hazards that have caused damage to materials and historic features. The research in this article concerns one of the oldest metallic structures that still exist in Egypt namely an iconic landmark on the shore of the Mediterranean Sea, the "Al-Burullus-lighthouse". Climate change threatens the state of the lighthouse. The research involves full architecture will conduct to the necessity of put an urgent intervention plan for documentation of the lighthouse, and monitors the natural and climatic changes which are facing the lighthouse through Coastal hazard wheel (CHW) analysis. Where the analysis finding that the high rise of sea level are most effect on the decay and erosion of coastal shores and gradually the lighthouse become more near from sea as research presented ... this phenomena saving the lighthouse. The article describes an urgent technical plan regarding risk management options for restoring the historic image and archaeological value of the lighthouse, which has a significant impact on developing an integrated strategy for managing the process of preserving the lighthouse and the site, and then integrating and including in development plans of the city and surrounding urbanization.
