Abstract
While design optimization of buildings seeks to improve energy efficiency and, thus,
leads to greenhouse gas emissions reduction, the thermal performance of buildings can be
compromised. Thermal performance is an important aspect as it directly affects the health and wellbeing of occupants. This study aims to investigate using a simple simulation tool to examine the
correlation between a set of building physical design parameters such as orientation, shading and
shape, optimization of which helps to make a positive impact on the thermal performance of the
building in a cold climate zone. The thermal performance simulation tool Passive Design Assistant
(PDA) was used to build a simulation model and test the interdependence between the design
parameters and thermal performance. The results indicate that modifications of building's
parameters such as orientation and shape or the addition of shadings lead to improvements of the
internal thermal temperature, heat gain and loss, hence the optimal parameters should prevail. A
case study for cold climate is analyzed, in Nur-Sultan, Kazakhstan, the optimal orientation for the
squared building is 30° from East to South (building rotated 120°) and the optimal building’s shape
is rectangular, which attracts up to 2.6 times higher solar gains than the square one. Moreover, the
use of shadings can regulate the internal temperature of the building by 2 °C. General
recommendations based on the findings are made and could be considered in the earlier stage of
building design and construction processes.
