Abstract

This paper aims to highlight the potential of solar water heater installations in Morocco. The project involves the comparison of active and passive solutions for energy efficiency in buildings. To this end, a numerical simulation model of solar water heater installations is created under TRNsys. Three hot water demand scenarios (Low, Standard, and High) were taken into account for the six climatic zones defined in the Moroccan thermal regulation of constructions. The same software (TRNsys) is used to model a pilot building consisting of 16 flats. Energy efficiency actions have been applied to the building envelope (insulation and glazing) and simulations are made for the six areas. The simulation results comparing energy and financial savings show the influence of subsidized gas prices on solar water heaters’ relevance despite significant energy savings. This work proves that solar water heaters will be a primary obligation for Morocco, taking into account changes in butane gas prices.

Highlights

The Moroccan energy situation assessment has revealed that the country imports about 95% of its energy needs, 60% of which is oil, equivalent to 9 million TOE [1]
Projections of energy needs for the 2020s expect a growth of 5% to 6% for electricity consumption, which should be around 1000 kWh per inhabitant annually [3]
The results presented come from the application of first the insulation, double glazing, and all conditions required by Moroccan thermal regulation of building construction as passive solutions

Summary

Introduction

The Moroccan energy situation assessment has revealed that the country imports about 95% of its energy needs, 60% of which is oil, equivalent to 9 million TOE (tons of oil equivalents) [1]. This national energy bill weighs heavily where 20% of total imports and. 50% of the trade deficit represent only oil Despite this situation, Morocco supports gas users, industry, and households where domestic gas price support subsidies are close to. Electrical energy consumption increased from 487.38 kWh/person in 2000 to. The need for air conditioning (heating and cooling) is not negligible in many of the Kingdom’s major cities
