Abstract
"Urban agriculture, Nexus, and climate envelope are interdisciplinary topics where greenhouses are integrated into the urban and pre-urban context. Building-Greenhouse prototype (BGp) is a new integrated design developed and based on using advanced greenhouses generation, where high indoor climate control and efficient water and nutrient cycles continue to be achieved. The research analysed the Humidification and Dehumidification (HDH) techniques for building cooling, greenhouse climate control, and for water desalination systems. The research methodology is to explore applying the BGp on the governmental rural models in Egypt, where the occupants are suffering from numerous living, income, and environmental problems. The BGp is opening the door to apply decentralised urban communities, where autonomous energy, water, and food production could be achieved using brackish or seawater water. This research implemented a comprehensive analysis to develop a BGp for the governmental housing in Red Sea coast in Egypt. Designbuilder simulation analysis is used to develop the governmental rural dwellings, the greenhouse unit, and the Heating Ventilation and Air Conditioning system (HVAC) design. The performance of the integrated HVAC system is verified using ‘TRNSYS’ software simulations. The results confirmed that the integrated HVAC intervention could save 38% and 17.5-36% of the building and the greenhouse cooling loads, respectively, compared to the conventional systems. The integrated BGp application increases the occupant’s indoor living quality, the socio-economic impact, and self-sufficiency of food and water. The research discusses the BGp application in comparison to the Egyptian end-use energy and market, in addition to present an economic and ecological analysis.
