An apparent transformation of energy trade in developing countries such as the UAE directly impacts and influences the global energy dynamics. UAE is the largest global exporter of fossil fuel for energy generation and it is therefore a necessity to analyze the regional in-house energy market as a first from the demand-side improvement perspective. Due to the arid climatic nature of the country, we performed simulations on air-conditioning unit performance, for the largest emirate of Abu Dhabi, using a convoluted parametric effect of coefficient-of-performance and set-point temperature to understand the long-term impact on energy operation and its monetary implications to the UAE economy. The targeted sectors included commercial and residential as leading energy hungry consumers. An assessment of the present situation to optimally determined using DesignBuilder and EnergyPlus, indicated clear change in energy generation, consumption and greenhouse gas emission reduction. The effects were forecasted using long-range energy alternatives planning simulation tool to predict the national wealth savings and to assist in governmental policy making until 2030 as per the Abu Dhabi Vision. The savings amounted to millions of dirhams per sector based on the unique upfront tariff & subsidy structure of the UAE and an emission reduction of approximately 2500 thousand metric tons of CO2 equivalent per sector by 2030 as per the Abu Dhabi Vision 2030.
