Why we should change the way we environmentally assess building retrofits
On 09.05.2022 by Linus WalkerBuilding retrofits are increasingly assessed from an environmental perspective. Standard assessment methods, however, largely do not consider future developments and fail to take into account the state of climate emergency where the time horizon is substantially shorter than the expected building lifetime. Therefore a more forward-looking analysis is required. Including global warming, electricity decarbonization, and aligning the analysis period with 2050 goals give greater weight to material-based embodied emissions. I, therefore, claim that construction materials are substantially more relevant in the fight against global warming than currently considered in most assessments.

Photovoltaics on Buildings – Ugly and Expensive or an Opportunity for Creative Design?
On 01.02.2020 by Linus WalkerThe integration of solar energy technologies in buildings has been available for several decades. However, many buildings are still built without any PV or solar thermal collectors, which in my opinion is an intolerable situation.
