Near Zero-Energy Buildings in Lebanon: The Use of Emerging Technologies and Passive Architecture

Courtyards are traditionally associated with the Middle East countries, where climate and culture have given shape to a particular type of traditional architecture. The study evaluates the environmental and social impacts of courtyards in an educational building integrated with occupant’s interaction behavior. The case study of the University of Sharjah includes eight different courtyards unoccupied for many years, in different locations around the building with various proportions; the objectives were to examine and evaluate the impact of redesigning the interior spaces of the courtyards in terms of environmental and social aspects. The inductive and experimental approach were adopted in this research, where two surveys were conducted for the occupants, before and after the design applications. In addition to the use of eco-tech software for simulation. In conclusion, the results of surveys and interviews clarified the problem and offered some recommendations and simulation analysis provided recommendations and guidelines for designers.

Summary To improve the energy efficiency in buildings, a computational optimization method is suggested in this article. The method is designed based on the structure of the adaptive façade. This type of façade system can adjust its visible and thermal transmissivity for actively changing weather conditions. The main concept of this system is the optimization process. This process integrates the DesignBuilder as the building energy simulation tool with an optimization method, called arithmetical optimization algorithm, through the MLE+ toolkit. It is notable that the proposed approach can be applied to different building types and is also not involved in any specific optimization tool. In this regard, two case studies, a typical single office room, and a medium office building are selected to show the capability of the presented approach to improve the energy effectiveness of the building. Based on the results, the energy consumption is decreased by 15.0%–29.1% for the first case study and 14.3%–22.4% for the second case compared to the static façades. The adaptive façades' potentiality is indicated by the important achievements in this study.

“…Accordingly, these strategies should be taken into account when designing net zero energy (NZE) settlements [7] and positive energy districts (PEDs) [8] and communities [9]. Compared to net/near zero energy buildings (NZEBs), which are currently being worked towards with the goal of building energy efficiency in Europe [10], the enlargement of the scale of NZE and PE districts empowers the enhancement of energy efficiency and microclimate mitigation solutions' implementation in common areas and facilities, such as pavements, roofs, and gardens [11]. Therefore, on the one hand, energy sharing and management can be optimized within the energy community due to improved flexibility.…”

Combined Effect of Outdoor Microclimate Boundary Conditions on Air Conditioning System’s Efficiency and Building Energy Demand in Net Zero Energy Settlements

In Europe, near zero energy buildings (NZEBs) represent the new frontier of energy efficiency in the built environment. Shifting the scale from NZEBs to net zero energy (NZE) settlements represents the opportunity to achieve further energy, environmental, and cost benefits, thanks to shared energy management, optimization of renewable energy systems, and microclimate mitigation. In particular, the last aspect takes advantage of the implementation of local microclimate mitigation strategies at a larger scale to improve settlements outdoor environmental conditions and citizens’ wellbeing. Furthermore, this inter-building scale mitigation involves relatively less severe working boundary conditions for buildings, able to both reduce building energy demand and improve HVAC (heating, ventilation, and air conditioning) system’s efficiency. In this study, this potential extra-energy saving, achievable without additional costs, is explored within the framework of a NZE settlement built in Italy thanks to an ongoing Horizon 2020 project. Improved working conditions for the operating air conditioning system and building energy savings thanks to settlement scale opportunities for microclimate mitigation are assessed. Findings show how this effect represents a further non-negligible energy-efficient and environmentally sustainable benefit achievable through the design and construction of NZE settlements. Potential energy savings are up to 24% when considering the double effect of microclimate mitigation.
