Abstract
DESIGN PROCEDURE FOR NEAR ZERO ENERGY BUILDING IN SAUDIA ARABIA
*A. M. Abdelaziz and M. Abouelela
ABSTRACT
The Zero Energy Building (ZEB) concept ensures that building electrical loads are controlled in such a way that the net energy consumed from the utility grid over a period of time (monthly / yearly) is near or almost zero. Recently, the number of residential buildings in the Kingdom of Saudi Arabia has increased with the increase in governmental support for citizens to own private homes. This results in increasing the energy consumption in the country. It is noted that, the energy consumption in the Kingdom of Saudi Arabia from residential buildings is about 40 percent of the total Consumption. The main objective of this work is to propose a design approach for engineers working in building design in order to implement a Near Zero Energy Building (NZEB) when solar energy is available at residential buildings. The work includes a study for implementing an Economic Building using the NZE concept, in accordance with policies to support renewable energy in the Kingdom of Saudi Arabia. Throughout this work, an example of a real estate developer working in the Saudi market, specifically in the city of Riyadh, will be analyzed and improved. The Design Model for a Residential House in Riyadh is introduced and analyzed. Architecture conceptual design, electrical design and sustainability analysis are given in details. Optimization for thermal isolation, and electric loading are used to reduce energy consumption. A solar PV system is proposed in order to achieve NZEB for a 350 m2 house and the money payback period is estimated using 3D residential Revit software.
