Climate calculator for halls - comparison of different framework materials

Compare the climate impact of different framework materials in hall buildings with the same internal volume and calculation assumptions.

This tool has been developed to provide an early and clear comparison between different framework solutions for hall buildings. By starting from the same hall building, the same dimensions and the same methodology, it becomes possible to see how the choice of material affects the climate footprint and what differences arise between the alternatives.

Calculation assumptions

  • Climate impact, GWP-GHG (i.e. without bound biogenic carbon) is calculated per m² BRA (usable area) for Module A1–3, A4 and A5spill.
  • All material alternatives are based on the same internal volume which has an internal wall dimension of 23.7 × 48 m and a free internal height of 5 metres.
  • Only the framework is included in the calculation and no foundation of columns, walls and roof including the secondary load-bearing structure between the roof truss beams.
  • The choice of roof and facade is assumed to be independent of the framework solution.
  • The Swedish National Board of Housing, Building and Planning's typical generic climate database (published in 2025) has been used for GWP-GHG, as well as transport for everything except glulam, which is based on updated EPDs and provides an industry average for Swedish-produced glulam.
  • Wind load terrain type II qp = 0.717 kN/m² and form factors according to SS-EN 1991-1-4, snow load zone 2.5, self-weight of external roof 0.5 kN/m², self-weight of external walls 0.5 kN/m².
