“…Level-1 of energy retrofit: This basic retrofit involves mostly low-cost energy efficiency measures such as replacement of lighting fixtures with LED units and weatherization of building shells to reduce air infiltration. As detailed in several other studies, the estimated average savings from a Level-1 retrofit program are about 8% for all building types based on the simulation analysis carried out for several Arab countries as well as case studies reported for residential, commercial, and governmental buildings [2,10,[42][43][44][45][46][56][57][58]. cooling system replacement, and installation of automated control systems.…”

“…cooling system replacement, and installation of automated control systems. While deep retrofits are typically costly, they can provide significant energy use savings exceeding 50% as noted in several reports and as noted for the optimal analysis conducted for the Arab region [2,10,[42][43][44][45][46].…”

“…The analysis is based on a bottom-up approach of the building stock to account for the characteristics of the building stock in the Arab region. The details of the bottom-up approach, as well as the specific characteristics of the building energy models used in the simulation and optimization analyses are outlined in the literature for various countries in the Arab region [2,[10][11][12][42][43][44][45][46].…”

“…Similar reductions in both electrical peak demands and carbon emissions can be achieved. While the required investments to implement these energy efficiency programs can be significant as highlighted later for the special case of Saudi Arabia in Table 23, the economic benefits can be substantial for most Arab countries as documented for the GCC countries [2,[42][43][44][45][46]. The retrofit programs can start initially with non-residential buildings since they provide higher energy savings per unit floor area than residential buildings for the Arab region [56].…”

The paper overviews the current energy demand trends in the building sector for the Arab region using reported historical energy consumption. Moreover, the paper describes the current energy efficiency policies and regulations for all the Arab countries specific to both residential and commercial buildings. Finally, the paper evaluates potential benefits for large-scale energy efficiency programs specific to new and existing building stocks within the Arab region using a bottom-up analysis approach. The analysis of the available energy consumption for all the Arab countries has shown that the Arab region presents a significant variation in energy consumption levels between its sub-regions and countries. Indeed, the Arab region includes oil-producing countries such as Saudi Arabia with the largest energy use per capita in the World with over 9000 kWh/person of electricity used annually in buildings. However, the same region has the least developed countries such as Sudan and Yemen with the lowest energy use per capita in the World with barely 100 kWh/person/year of electrical consumption. The review of the existing regulations has indicated that several Arab countries have not implemented any energy efficiency codes and standards for building envelope, lighting, heating and cooling equipment, and appliances. A cost-effectiveness analysis has indicated that the Arab region can incur significant benefits in upgrading the energy efficiency of its new and existing buildings especially its households. Specifically, the adoption and the enforcement of stringent energy efficiency codes for new residential and commercial buildings can result in a reduction of 12.7 TWh/year in final annual energy consumption for the Arab region. Moreover, retrofit programs targeting existing buildings can save up to 470 TWh or a third of the building sector final energy consumption per year after 2030. Combining comprehensive energy efficiency requirements for new buildings and extensive retrofit programs for existing buildings would reduce the total final energy consumption of the building sector in the Arab region by 600 TWh by 2030 and by 900 TWh by 2050 if all the energy programs start to be implemented by 2020.
