New research reveals 76% of European institutional investors with stranded commercial real estate assets – buildings experiencing reduced capital value, leasing or future liquidity due to poor energy performance – have seen their value decline by between 20% and 40% over the past three years.

This is according to new benchmarking research launched by re:sustain, the leading science-based technology platform which optimises the energy consumption of real estate assets. Re:sustain surveyed 200 European real estate institutional asset managers in the UK, Germany, France, Netherlands, Spain and Italy, with a combined AUM of €296 billion.

Two thirds of those surveyed (63%) said that 20-40% of their commercial real estate portfolio has poor energy consumption i.e. that which is materially above expected energy benchmarks for that asset type and location. Over half 57% of those surveyed said that between 10% and 50% of their real estate assets were stranded, posing a huge problem for the sector.

The findings show that at a country-specific level, investors in the Netherlands and France face the greatest stranded asset challenge, with those in Italy, Germany and Spain having lower numbers of poorly performing buildings in their portfolios.
