When aiming to reduce the carbon footprint (Co2e) of a single construction project, it is essential to set
the goals at the early stages of the planning process. However, setting these early design goals is only a
first step and efficiently comparing different design options at early stages can be difficult for the draft/
preliminary design phase when it’s missing detailed information concerning material choices. One way of
estimating the overall effect of buildings carbon footprint and energy efficiency is by using building form
factors to compare different design solutions. There are already few form factor estimation methods for
energy efficiency in use (Lylykangas, K., Lylykangas et.al 2015), but for GWP (Global Warming Potential) or
carbon footprint estimation, there are no applicable methods developed.
However, based on ourrecent studyform factorcan be assessed bycomparing completed design solutions
and their carbon footprint. By using groupings based on construction classifications (Construction 2000
Classification, 2010), we can make a comparison in regard to carbon footprint for different design options.
In this study, it is shown how to use building form factor for low carbon construction by means of case
studies estimating building carbon footprint using EU Level(s) and showing the basis of methodology
(Keskisalo & Matveinen, 2020). The proposed form factor weighted by sub-values for GWP is at early
stages, but it can be shaped to be more accurate with more studies and data of the completed building.
Keywords: form factor, LCA, building design, architecture, EU Level(s)
