Speech title: Energy-efficient Evaporative Cooling Technologies for Agriculture
Abstract: For any nation, primary sources of energy consumption are involved in: heating, cooling, humidification, dehumidification, ventilation and/or air-conditioning (HVAC), which may be required for various applications. Currently, developing countries worldwide are facing extreme energy shortage, therefore, low-cost and energy-efficient HVAC systems are principally required. The low-cost HVAC systems are required not only for humans’ thermal comfort but also for various industrial as well as agricultural applications e.g. greenhouse air-conditioning, agricultural products’ (fruits and vegetables) storage, and animals’ (livestock) air-conditioning etc. In this regard, various innovative cooling and air-conditioning technologies have been introduced worldwide. Consequently, in this keynote speech, evaporative cooling and adsorption cooling based HVAC technologies are explored. These technologies are environmentally safe and can be simply operated by water or low-grade waste heat. The low-grade waste heat can be supplied economically by many ways e.g. solar thermal energy, natural coal, bio-gas and/or bio-mass etc. From the prospective of evaporative cooling, the speech focuses on Maisotsenko cycle (M-cycle) based evaporative cooling conception in comparison with conventional direct and indirect evaporative cooling. While adsorption cooling and desiccant air-conditioning systems are focused from the prospective of thermally driven systems. Importance of selection of refrigerant and adsorbent/desiccant is also highlighted. Based on geographic and climatic conditions of the developing countries, the role of temporal and spatial variation for the development of sustainable HVAC system is addressed.

Speech title: Design Challenges for Environmentally Friendly and Sustainable Cities in Hot and Arid Areas
Abstract: Recent years have observed a major change in temperature, especially in arid and hot areas. This has forced researchers and urban planners to confront the challenges of significant change, such as creating environmentally friendly and sustainable cities. One of the most significant problems that designers focused on was how to deal with the challenges that affect arid and hot climates, specifically drought, desertification, and a lack of vegetative cover. Furthermore, urban areas in hot and dry regions, especially ancient and historical ones such as Baghdad, which dates back 1,260 years, are affected by air pollution caused by gases and fumes from manufacturing operations and transportation, emphasizing the urgent need to raise environmental and pollution awareness. This session will discuss the issues encountered when developing environmentally pleasant cities using ENVI-met software, a German application that specializes in designing sustainable and environmentally friendly cities. Among the design problems that will be discussed is the significance of afforestation strategies in reducing temperatures and enhancing thermal comfort using thermal comfort indicators such as PMV, PPD and TMRT. The role of the sky view factor in building engineering design, as well as its relationship to aspect ratio, which contributes to reducing the distance between buildings and reducing the effect of solar radiation on facades and corridors, thereby contributing to reducing heat emissions, will be discussed. Environmentally friendly materials that contribute to improving solar reflection will be looked at, as well as the significance of the albedo coefficient, which must be considered when reducing the amount of heat absorbed by surfaces and corridors.
