Abstract: (464 Views) |
Objective: The latest energy balance report (2013-2021) shows a 27.3% increase in the energy consumption of residential buildings. Building components react differently to climate. Unconventional construction in the rural lowlands of Rudsar County increases energy consumption. The study aims to optimize the opening dimensions of houses to reduce energy consumption in this area.
Method: In this context, the first step is to assess the current needs of a typical residential building in the region, followed by the optimization of its energy-intensive components. To carry out this research, Climate Consultant 6.0 software was used to assess the building's climatic design requirements, while Expert Choice 11 software was used to prioritize the energy consuming components using the Analytic Hierarchy Process (AHP). The selected building was modelled in Rhino 7 and its energy simulation was performed using the Honeybee and Ladybug plug-ins within the Grasshopper environment. Finally, the Octopus plugin was used for parametric optimization.
Results: The results of the single objective optimization focused on the energy consumption intensity of the building, indicating that optimizing the window proportions in the kitchen and living room zones had a more significant impact on reducing energy consumption compared to other zones. In addition, openings with canopies on the south façade of the living room had fewer constraints in modifying the opening proportions than those in the south room on the same façade. In summary, both the north and south facades offered greater flexibility in selecting variable window proportions during the design process.
Conclusions: Selectively among the optimal forms that are more commonly implemented, the kitchen zone was found to have an energy consumption difference of 3.58 kWh per square meter per year compared to the existing conditions, with a Window-to-Wall Ratio (WWR) of 31.75% for the northern façade and 8.42% for the eastern façade. Of the total window area used on the exterior of the building, 34% corresponds to the north elevation, 29% to the south elevation, 23% to the east elevation, and 14% to the south elevation, representing the average optimal conditions for the building. Therefore, based on the average optimization results across the zones, reducing the WWR on the south and north facades of the north room to 16.54% and 2.87% respectively could lead to a reduction in energy consumption intensity of 3.52 kWh per square meter per year compared to the current state. |
