| Abstract: | The building sector significantly contributes to global energy consumption and greenhouse gas (GHG) emissions. To reduce this, energy-saving measures should be implemented in buildings. However, this approach only considers the energy reduction during the building’s use phase, overlooking energy consumption and GHG emissions during the lifecycle of the measures. Antea Group provides energy-saving advice. However, their software does not consider embodied energy and resulting emissions. Consequently, Antea Group cannot advise its clients as comprehensively as they wish. Therefore, the objectives of this research are 1) determine the lifecycle global warming potential (GWP) and cumulative energy demand (CED) for twenty-six products of six advised energy-saving measures, and 2) ascertain the effects of this knowledge on the decision-making process. The results show that the greatest GWP, CED, and financial costs are associated with transitioning from energy label E to A or Energy Neutral. Furthermore, it was concluded that only selecting products with the lowest financial payback period, leads to a higher GWP and CED. This can be a risk, since clients prioritise the lowest financial costs and employees tend to focus on the client’s demands. Nevertheless, clients and employees want to change their prioritisation in future projects. Therefore, several recommendations are proposed. |
