Iran is one of the developing countries. Even though buildings in Iran also are accounted of 40% of all energy used in the region (Mahdavinejad,….) but compared to European countries the building sector consumes six times more energy (Asgar, 2014).Amongst all building types, tall buildings use more energy due to deep plans and provision of HVAC to maintain comfort levels (Holford and Hunt, 2003). This building looks into tall buildings and specifically in office types where more people are allocated in limited space and hence demand more energy.

This building looks into tall buildings and specifically in office types where more people are allocated in limited space and hence demand more energy. However, the region has a tradition of successful climatic conscious design solutions such as courtyards hence the paper aims to investigate the impacts of applying the traditional layout of courtyards to contemporary tall buildings in the form of atria in the semi-arid climate of Middle East. Cubic shapes are the most common used building forms amongst high-rise buildings in the world Alaghmandan et al., 2014, therefore, this paper looks into the square plan shape tall office buildings with no HVAC. Moreover, it provides insight of the differences in energy consumption to maintain comfort levels of different atria layouts in tall office buildings with a square plan shape. Dynamic Thermal Simulation (DTS) tool called Design Builder has been used to achieve the target. The software provides results of the prototypes over an annual period of time and compares then with non-atria building.

Tall buildings tend to have an increasing appetite for energy due to deep plans and provision of HVAC to maintain comfort levels especially in the Middle East with its hostile environmental conditions. However, the region has a tradition of successful climatic conscious design solutions; therefore, the paper aims to investigate the impacts of applying the traditional layout of courtyards to contemporary tall buildings in the form of atria. It also examines through a simulation technique the comparative energy consumption in relation to a number of different atria layouts. Moreover, it provides insight of the differences in energy consumption to maintain comfort levels of different layouts in tall office buildings. Dynamic Thermal Simulation (DTS) tool called Design Builder is used to achieve the aim. The software provides results of the prototypes over an annual period of time. By using Design Builder DTS tool the optimum form of atria type has been verified in semi-arid climate for rectangular and square plan shapes. It is concluded that rectangular shape buildings aligned on the east-west axis with atria orientated towards south seem to be the best option in using less energy to provide thermal comfort annually.
