AP19175447 “Optimization of topology of enclosing structure materials”

Project Manager: Karashbaeva Zhanat, PhD

Funding source: GF YOUNG SCIENTISTS ON THE PROJECT “ZHAS GALYM”

Project objective: to minimize energy consumption in the building by optimizing the topology of the environment, i.e. the location of the insulating material inside the walls. Both sensible and latent heat transfer are taken into account.

Years of implementation: 2023 – 2025

Amount of funding: 23,979,625.75 tenge

Minimize energy consumption in a building by optimizing the topology of the environment — that is, by adjusting the placement of insulation material within the walls. Both explicit and hidden heat transfer are taken into account.

Energy saving has been elevated to the rank of state policy in almost all countries, including Kazakhstan. According to statistics, more than 30% of the world’s energy consumption is accounted for by the building construction sector. For this reason, improving the energy efficiency of buildings plays an important role in solving global energy problems. The concept of transition to a green economy for 2021–2030 emphasizes the importance and relevance of the energy saving problem in the construction industry of Kazakhstan.
