Minimizing the Cost Gap between Net Zero Energy and Conventional Buildings

Abstract
This study investigates the cost barriers that keep decision-makers from implementing the Zero Energy Building (ZEB) concept. The fundamental reason for this research is the current scarcity of energy resources and the detrimental effects of nonrenewable energy, which produces significant amounts of Carbon Dioxide. As a result, more countries are planning to convert traditional buildings to Zero Energy buildings. However, they have recognized that there are additional challenges to overcome. Most studies were related to the cost of integrating ZEB technology, such as the high initial cost of adding renewable energy systems in comparison to the end cost of the construction. This paper shows the following gaps: 1. Energy-saving calculations using ZEB in different locations are needed, 2. Life cycle cost analysis is needed to clarify the potential of ZEB, 3. There is a lack of comparative studies between NZEB and conventional buildings' cost, and 4. There is a considerable gap in studying the high initial cost of ZEB.
