Renewable Energy Technologies in Residential Buildings in Hot Humid Regions and Their Implications Case Study: Jeddah City.

Abstract

The buildings sector represents a large part of energy consumption in the world at a rate that exceeds one third of public consumption in all its forms. It considers to be one of the most important sectors that contribute to achieving sustainable development. Many countries have been interested in using different types of RnE. This desirable aim is to be achieved by Vision2030 KSA. It aims to generate 9.5 GW of RnE by 2023, which is equivalent to 10% of the total produced energy. The is to mitigate the resulted impact of the power plants that produce pollutants and high percentage of CO2 emissions. This paper aims to find effective ways to use RnE in residential buildings as well as identifying the efficiency of using different types of energy. This raises questions about the types of RnE that can be used and how much is the value of saving in electricity consumption after using RnE technologies? what are the angles through which the largest amount of electrical energy can be generated form PV. This paper consists of four different parts that are formed in this topic. First, is concerned with studying some concepts of RnE and knowing their effects on the built environment. The second part comprises Climatic analysis to study RnE that can be used. The third part will use simulation programs as analysis platform and a 3D model of an existing residential building in Jeddah. This is to test how to use RnE technologies to operate it. The final part will show results and conclusion.
