Typology of residential blocks in Zanjan city with the aim of evaluating thermal load

Volume 14, Issue 2 (Summer 2024)
Abstract
Aims: With the continuous growth of urban population and the development of cities, the demand for energy in the building sector, especially in residential areas, has significantly increased. The configuration and form of buildings, along with their architectural and structural features, have a noticeable impact on the energy consumption of buildings and environmental sustainability. The main objective of this research is to assess the thermal performance of buildings at the scale of the neighborhood unit.

Methods: This research was conducted using quantitative research methods and sensitivity analysis. The data collection methods included gathering information from credible library and online sources, as well as conducting field visits.

Findings: Research findings indicate that courtyard patterns are considered the most efficient, while linear patterns and discontinuous courtyard patterns are regarded as the least efficient residential block patterns in Zanjan. Furthermore, there is a significant correlation between energy consumption and layout and form indicators of the blocks, as well as moderate relationships with block proportions. The most efficient forms are octagonal and square shapes, and patterns with a length-to-width ratio ranging from 1 to 1.6 generally exhibit better energy performance.

Conclusion: studying and identifying efficient and inefficient patterns is important to reduce energy consumption in future design.
