About the project

Challenge, approach and results.

In recent years, the energy crisis has become a global challenge requiring swift and effective solutions. With high energy prices, depletion of fossil fuels and rising greenhouse gas emissions, the world faces the urgent need to transition to sustainable practices. Architectural thinking about the design of buildings such as ZP Magdalena emphasises the integration of functionality, aesthetics and energy efficiency. He calculated the heat losses of the existing façade of ZP Magdalena in January and compared them with solar radiation gains, whereby the losses proved to be considerably greater than the gains. Additionally, he analysed the impact of external shading devices (brise-soleils) on the shading of the building and found that ZP Magdalena without shading would be completely overheated, which would require a great deal of energy for cooling.

Problem

In recent years, the energy crisis has become a global challenge requiring swift and effective solutions. With high energy prices, depletion of fossil fuels and rising greenhouse gas emissions, the world faces the urgent need to transition to sustainable practices. Sustainable construction focuses on reducing energy consumption, using renewable sources, improving quality of living and minimising environmental impact.

This includes the use of energy-efficient materials, natural lighting, passive forms of heating and cooling, and optimisation of thermal insulation.

Solution and Method

Architectural thinking about the design of buildings such as ZP Magdalena emphasises the integration of functionality, aesthetics and energy efficiency. Planning takes into account local climatic conditions, solar paths, wind and natural features to ensure the best utilisation of natural energy sources and reduce the need for artificial heating or cooling. ZP Magdalena was designed as an example of contemporary architecture with the aim of minimising heat losses, maximising the use of sunlight for natural lighting and cooling spaces with the help of architectural elements such as external shading devices (brise-soleils).

This diploma thesis focuses on the comparison of different façade systems using the example of the ZP Magdalena building, specifically glazed-ventilated façades compared with conventional contact façades.

Results

He calculated the heat losses of the existing façade of ZP Magdalena in January and compared them with solar radiation gains, whereby the losses proved to be considerably greater than the gains. Additionally, he analysed the impact of external shading devices (brise-soleils) on the shading of the building and found that ZP Magdalena without shading would be completely overheated, which would require a great deal of energy for cooling. The author in the diploma thesis also presented the sixth dimension of BIM (Building Information Modeling), with which he demonstrated that simulations of heat losses can precisely define the quality of the façade envelope and predict thermal bridges in buildings.

The diploma thesis thus contributes to understanding the energy properties of different façade systems and emphasises the importance of using advanced technologies to improve the energy characteristics of buildings.
