In the analysis by Brix & Kamp A/S, two different types of balconies with steel railings were compared for a specific project - a Hi-Con balcony in ultra high performance concrete and a steel balcony. Both types of balconies were carefully assessed based on various factors, including weight, materials, and construction processes.
Both balcony variants have the same dimensions, namely a length of 3.55 meters and a width of 1.9 meters, which corresponds to a total area of 6.75 square meters. Both types of balconies are equipped with railings on three sides, made of steel.
For the variant study, Hi-Con's EPD (Environmental Product Declaration) has been used for phases A1-A3. For phases C3 and D, generic values for concrete elements have been applied. All other building materials have also been assessed using generic values.
The analysis has been conducted using LCAbyg 126.96.36.199 and includes the calculation of the total CO₂ emissions over a period of 50 years.
