MSc thesis from Themes 2 and 7 presented: Comparative LCA and LCC of Sandwich Precast Concrete Walls with BIPV
Master students Aanuoluwapo Oguntadefrom and Patrick Abu-Undiyaundeye from Dalarna University presented their thesis work, comparing a BIPV concrete wall with a regular concrete wall from an environmental and economical perspective. The walls compared represent wall solutions offered and produced by SOLVE-partner company Ulricehamn Betong AB (UBAB).
(Image removed) Results for a case study building in Gothenburg showed that, while the cradle-to-gate environmental impact of the BIPV wall studied is higher than for the concrete wall, the BIPV wall performs better with respect to global warming potential, primary energy use and acidification, when taking into account the replacement of grid-electricity by solar energy. The concrete wall studied has a lower impact on eutrophication and ozone depletion. LCA results assume the use of an environmental top-class PV module.
From an economical perspective the results depend highly on the (future) electricity spot-price, where the solar wall option yields a better Life Cycle Cost Analysis than the concrete wall if average spot-prices are about 0,6-0,7 SEK/kWh or higher.
The full thesis report is expected to be published in DiVa this summer.
