Abstract
Buildings are responsible for the consumption of around 37% of energy in the world and account for one-third of global greenhouse gas emissions. In Jordan, residential buildings make up 72% of the total share of buildings due to the increased demand from the rise of the population. Embodied Carbon has been under-researched in Jordan and there are very few studies that address the carbon emissions of buildings. Furthermore, it is not yet a common practice to investigate embodied carbon (EC) and Operational Carbon (OC) of buildings following a holistic approach in Jordan. This study aims to investigate the intricate relationship between EC and OC to assess the feasibility of carbon reduction of the housing stock in Jordan. To achieve this, this study has developed the foundations for a stock model that will be subsequently developed using data from the housing survey issued by the Department of Statistics (DOS) and the Jordan Green Building Council (JGBC) surveys. Dynamic thermal simulation tools were then used to evaluate the stock’s current and future performance. Lastly, refurbishment measures packages were explored to improve the whole life cycle, considering carbon emissions, cost, and thermal comfort simultaneously, which will be investigated to find the optimum solutions with different interventions. The findings of the study indicate that life cycle carbon (LCCO2e) reduction of up to 63% could be achieved for the proposed refurbishment measures with a 60% reduction in life cycle cost (LCC). The metric of cost per carbon saved is a key indicator in assessing the economic efficiency of refurbishment strategies. The results translate to a refurbishment cost of 105.3 million JOD per MtCO2e saved. The results help identify the potential reduction of LCCO2e of housing stock in Jordan. In doing so, it can constitute a basis for reducing the carbon emissions for different building typologies in Jordan.
