“…To study and investigate renewable technologies, Wittchen et al (2010) utilized two on-site renewable technologies: PV and flat solar thermal panels in order to generate the energy needed to meet the NZEB. This technology is the most commonly used in Denmark (Wittchen et al, 2010). Venturi et al (1997) discussed the technology options for the energy aspects which seem to not to be sufficient to ensure the diffusion of a nNZEB model in achieving a nNZEB objective; a significant role be played by designers and architects (Venturi et al, 1977).…”

Residential buildings contribute a significant share of energy consumption in Jordan, consuming 23% of total energy demand. It is the highest electrical energy consuming sector in Jordan, where it accounted for approximately 43% of the total electricity consumption in the year 2016. Therefore, improving the energy performance of existing residential buildings in Jordan is likely to reduce energy usage (approach net zero energy) and would be a means to minimizing national electrical consumption. A typical house model located in Irbid is selected as a case study for the near zero energy design and saving energy objective. The study investigates the economic and computational potential of various integrated passive and active design systems for the Jordanian residential building sector, by focusing on several parameters including orientation, layout, type of insulation, type of windows, shading system, type of ventilation system which used a comprehensive and detailed model of the natural convection air-cooled condenser integrated to stack (NCACC) as new efficient ventilation method, and using of two renewable energy technologies; PV and flat plate solar thermal collector during the design of the buildings. This study uses three-strategies of building energy analysis in order to achieve near Net Zero Energy Building (nNZEB) in Irbid, Jordan. Two approaches (computational and analytical) could be utilized for the identification of energy building performance analysis. A dynamic building energy modeling and simulation software with different climatic conditions was utilized to identify the best building energy model. A suitable economic evaluation criterion was used to estimate the payback period of all systems applied.

Buildings consume approximately 40% of the world's primary energy use. Considering the total energy consumption throughout the whole life cycle of a building, the energy performance and supply is an important issue in the context of climate change, scarcity of energy resources and reduction of global energy consumption. An energy consuming as well as producing building, labelled as the Zero Energy Building (ZEB) concept, is seen as one of the solutions that could change the picture of energy consumption in the building sector, and thus contribute to the reduction of the global energy use. However, before being fully implemented in the national building codes and international standards, the ZEB concept requires a clear understanding and a uniform definition.The ZEB concept is an energy-conservation solution, whose successful adaptation in real life depends significantly on private building owners' approach to it. For this particular target group, the cost is often an obstacle when investing money in environmental or climate friendly products. Therefore, this PhD project took the perspective of a future private ZEB owner to investigate the cost-optimal Net ZEB definition applicable in the Danish context.The review of the various ZEB approaches indicated a general concept of a Zero Energy Building as a building with significantly reduced energy demand that is balanced by an equivalent energy generation from renewable sources. And, with this as a general framework, each ZEB definition should further specify: (1) the connection or the lack of it to the energy infrastructure, (2) the unit of the balance, (3) the period of the balance, (4) the types of energy use included in the balance, (5) the minimum energy performance requirements (6) the renewable energy supply options, and if applicable (7) the requirements of the building-grid interaction. Moreover, the study revealed that the future ZEB definitions applied in the Denmark should mostly be focused on grid-connected ZEBs -Net ZEBs, and the annual primary energy balance.The Life Cycle Cost (LCC) analysis conducted with a study case of a multi-storey residential Net ZEB aimed to determine the cost-optimal "zero" energy balance, minimum energy performance requirements and options of supplying renewable energy. The calculation encompassed three levels of energy frames, which mirrored the Danish low-energy building classes included in the current building code, and ten renewable energy supply systems including both on-site and off-site options. The results indicated that although the off-site options have lower life cycle costs than the on-site alternatives, their application would promote renewable technologies over energy efficiency measures. Thus, they oppose the Danish plans to gradually make the energy performance requirements stricter. Moreover, the results showed that district heating is a less cost-attractive solution than a ground source heat pump for a private building owner. Finally, with 2010-level of energy prices, cost-optimal "zero" energy balance accoun...
