Natural disasters are inevitable and it is almost impossible to fully recoup the damage caused by the disasters. But it is possible to minimize the potential risk by developing disaster early warning strategies, methods using the new technology applications which play a crucial role in efficient mitigation and management of disasters. This paper describes the importance of the remote sensing and Geographical Information System (GIS) in evolving a suitable strategy for disaster, crises and risk management using these technologies. The main objective of this paper is to make a Preliminary risk management plan (it is a logical and systematic method of identifying, analyzing, treating and monitoring the risks involved in any activity or process. This process helps Administrations to focus on priorities and in decisions on deploying limited resources to deal with the highest risks) using the Environmental risk map of the greater city of Cairo demonstrating the most high-risk administrative areas in the city, supported by field evidence and different sources of information. to reduce the loss of life and property and protect the Nation from all hazards, including natural disasters and other man-made disasters, by leading and supporting the Nation in a risk-based, comprehensive emergency management system of preparedness, protection, response, recovery, and mitigation. This study has shown that how can the early warning Applications can be useful in analyzing, Integrating and managing different datasets for predicting the environmental crises and disasters that may affect the urbanism inside the city and help in the preparation of the Risk management plan

Occupant satisfaction with indoor environmental quality (IEQ) in office buildings has been completely related to selfestimated job performance and, probably, to overall company productivity. Poor indoor environmental circumstances can negatively affect occupants' physical health through poor air quality, extreme temperatures, excess humidity, or insufficient ventilation and psychological health through inadequate lighting, acoustics, and ergonomic design. Sustainable or green building rating systems is attempting to address IEQ and occupant health concerns by providing healthier building environments. Although many qualitative studies claimed that improved IEQ also improves health and productivity and has provided substantial motivation to build green, quantitative studies are needed to prove these relationships. This research shows an outline of the results from a post occupancy evaluation (POE) study on indoor environment, occupant health, and wellbeing in two office buildings in greater Cairo: conventional building and green building certified using the Leadership in Energy and Environmental Design (LEED) Rating System; which is owned and occupied by the same origination. Evaluation of IEQ is based on 'Building Use Studies' (BUS) occupant questionnaire which applied in both buildings. This research highlighted that occupants productivity in office buildings can be enhanced through good building design, and provision of a high quality, healthy, and functional interior environment, that takes consideration of basic occupant needs.
