Engineering of Fire Disaster Mitigation (EFDM)
The increasing pressure from all Govt. and world bodies such as UNEPA has augmented the world-wide R&D programmes on development and characterization of water-mist and aerosol fire extinguishants. Halon fire extinguishants (CFC-based) CFCs Phase-out time-limit in India has already been timed out in 2010 for civilian fire protection and other uses under Montreal Protocol. Commercial fixed water-mist and aerosol fire systems are hardly in use in India. Hence, India needs low-cost water-mist fire extinguisher. No variable multiple fire load density based fire suppression system approach for characterizing fire extinguishing materials and designing the fire extinguishing system is reported in the literature. There are relatively very limited studies reported in literature on CFD modeling of fire suppression systems. The optimization of fire suppression systems in many applications is made more challenging and difficult. Concrete is one of the most commonly used building materials and practically no construction is complete without the use of concrete. Although the concrete is non-combustible in nature but when exposed to high temperature, changes take place in the properties of concrete both at the surface and inside the structural element. Relatively very less research data is available internationally on the fire behavior of structural elements under stressed conditions. Therefore it is required to promote more research programmes on the study of the behavior of structural elements made of concrete at high temperature.

Post Disaster Shelter Planning (PDSP)
Pre-fabricated houses/buildings, popularly known as ‘Prefab houses’ are becoming popular in Europe, Canada and United States. The uses of the Pre-fabricated houses in these countries are mostly for industry, office, tourism and luxury. The pre-fabricated buildings presently manufactured are generally of three types; Modular Homes; Manufactured Homes; and Mobile Homes. Mobile and manufactured houses are constructed in accordance with the HUD building codes in the U.S., while modular houses are constructed in accordance with the IBC (International Building Code). None of these designs are meant for the proposed purpose of disaster management. The transitory houses proposed in this project proposal do not fall in the categories indicated above and obviously the design will not match with the international building codes but will be solely for the purpose for which it is meant for in our country. Development of the proposed technology will be an addition towards the different measures of disaster management programs of the country.

Health Monitoring of Buildings using Wireless Sensor Network
The Structural Health Monitoring (SHM) process involves the observation of a system over time using periodically sampled dynamic response measurements from an array of sensors, the extraction of damage-sensitive features from these measurements and statistical analysis of these features to determine the current state of system health. In our country, traditionally, safety evaluation of buildings is being carried out through periodic visual inspection and some kind of non-destructive testing. The need for quantitative global damage detection methods that can be applied to complex structures has led to research into SHM methods that examine changes in the vibration characteristics of the structure. Structural health monitoring of buildings using WSN is important because it can greatly reduce routine maintenance and inspection costs, while providing an increased level of safety by damage identification in structural members.

Intelligent Building System for Model Residential Unit
The concept of intelligent building was stimulated by the development of information technology. Intelligent Building System (IBS) uses technology and process to create a building that is safer, more productive and more operationally efficient for its occupants. The major research in case of an IBS has gone into three main streams – advanced/innovative technologies, performance evaluation methodologies and investment evaluation analysis. To include advanced/innovative technologies in the buildings, the main focus has been on the development of system integration, network protocol and building subsystem services. The development of automatic control systems has resulted in Intelligent Buildings with a wide range of building automation facilities. The primary research focus will be given for the development of software with the use of automated diagnostic tools introducing neural networks, fuzzy logic, as well as other software-intensive, artificial-intelligence-based technologies designed to detect problems. Efforts will also be given to develop intelligent control method to be used in modern building management system for improving and optimizing the energy and environmental performance of buildings and also in the application of wireless technologies in the building.
