A single basin single slope solar still with 0.82mx 0.81m x 0.75m has been fabricated with G.I sheet and tested with different water depths of 2,3,4cm. Various solid and liquid sensible heat storage materials, Evaporative surface materials are used in the form of billets, in the still. To reduce glass cover temperature the outer glass was cooled by using sprinkler manually at regular interval of time. Theoretical analysis was performed and compared with experimental values. The performances of modified still were compared with conventional still of same size running under the same meteorological conditions. The solid sensible heat storage materials produces48% more productivity than conventional still. Liquid sensible heat storage material produces 19% more than conventional in till. The payback period of the still was 340 days.

Solar distillation is one of the important methods of getting clean water from brackish and seawater using the renewable energy of the sun. The passive type solar still represent most economical method to supply drinking water for domestic applications for decentralized level. Experimental measurements of solar distillation productivity for single slope still were conducted at the testing field of the Mechanical Engineering department, Coimbatore Institute of Engineering and Technology, Coimbatore, Tamilnadu, India. The influence of basin water quantity and amount of energy storage materials are examined and the performance is compared. The target of this research is to find best way to keep the excess heat by energy storage materials and release it during off-sunshine hours for increment in distillate output and efficiency. Various sensible heat energy storage materials like pebbles, blue metal stone, red brick, granites and white marbles were used as energy storage medium. The daily yield of black granite still is higher than other energy storage material stills and is equal to 3.216 kg/day/m2, which is 29% higher than that of the still without energy storage materials.

Indoor Environmental Quality (IEQ) is essential for the health and productivity of building users. The risk of overheating in buildings is increasing due to increased density of occupancy of people and heat emitting equipment, increase in ambient temperature due to manifestation of climate change or changes in urban micro-climate. One of the solutions to building overheating is to inject some exposed thermal mass into the interior of the building. There are many different types of thermal storage materials which typically includes sensible heat storage materials such as concrete, bricks, rocks etc. It is very difficult to increase the thermal mass of existing buildings using these sensible heat storage materials. Alternative to these, there are latent heat storage materials called Phase Change Materials (PCM), which have high thermal storage capacity per unit volume of materials making them easy to implement within retrofit project. The use of Passive Cooling Thermal Energy Storage (TES) systems in the form of PCM PlusICE Solutions has been investigated in occupied spaces to improve indoor environmental quality. The work has been carried out using experimental set-up in existing spaces and monitored through the summer the months. The rooms have been monitored using wireless temperature and humidity sensors. There appears to be significant improvement in indoor temperature of up to 5°K in the room with the PCM compared to the monitored control spaces. The success of PCM for passive cooling is strongly dependent on the ventilation strategy employed in the spaces. The use of night time cooling to purge the stored thermal energy is essential for improved efficacy of the systems to reduce overheating in the spaces. The investigation is carried within the EU funded RESEEPEE project.
