properties or sites prior to purchase. CO2 emissions can also be sig nificantly reduced through the use of renewable energies. District heating networks are used to meet heating needs. Properties in the portfolio are renovated sustainably as part of the ongoing modern isation cycle based on their location, quality and use. All options are examined with a view to achieving the targets set, up to and includ ing the use of energy-efficient household appliances. Alongside purely energy-related considerations, the materials used, reduced water consumption and how effluents and waste are dealt with also play a role. For Mobimo, landscaping, public transport links, car- sharing and e-mobility schemes, bicycle parking and charging sta tions for electric cars are all part and parcel of sustainable real estate. Mobimo works with partners that are also committed to sustain ability, especially in the case of development properties.
›› The energy consumption for electricity and heating corre sponds to the value billed for each property. ›› The calculation of CO2 emissions is based on heating systems, types of energy used and consumption including electricity. ›› From 2018, the calculation of energy-consuming space is carried out in accordance with SIA 380 (previously in accord ance with SIA 416/1), resulting in a reduction on paper. ›› Emissions factors were adjusted in 2018. These are higher for gas (scope 1) and for electricity (scope 2). They are lower for district heating and heat pumps (scope 1).

Objectives and results
Energy consumption and CO2 emissions have been constantly reduced since 2011 as a result of adjustments to the portfolio, the systematic implementation of Minergie or comparable construc tion standards for new builds and the substitution of high-emission energy sources.
Energyconsuming space (m²)
The share of oil as an energy source in the portfolio fell again yearon-year by over 12% (2018 share: 17.6%; 2017 share: 20.06%). The share of gas was reduced by almost 18% (2018: 23.5%; 2017: 28.6%). The shares of heat pumps (+53%) and district heating (+8.8%) increased in 2018 (see chart).

The top priority of the environment strategy is to cut the portfolio’s energy consumption and emissions. The impact of the measures implemented since 2011 was evident once again in the year under review: energy and emissions intensity were further reduced in 2018, by 9% and 4% respectively.

Verification: Independent Assurance Report, see pages 44 and 45. 1 Between 2011 (baseline year) and 2016 (end of the first five-year stage). 2 Between 2017 and 2018 (actual).
2011 to 2016: The first five-year stage was completed in 2016. Mobimo far exceeded the targets to increase energy efficiency, use renewable energies and reduce energy consumption that were set in 2011 for 2016. In the 2016 financial year, energy-consuming space increased by 49% compared with 2011. With an energy in tensity of 150 kWh/m2, performance was 17% better than the tar get value for 2016 (181 kWh/m2). With a value of 24 kgCO2eq/m2, the emissions intensity exceeded the reduction target for 2016 (28 kgCO2eq/m2) by 14%. 2017 to 2018: The second stage started in 2017. The sustainability strategy 2022 and related measures were approved in 2018. Energy- consuming space was reduced by 7% year-on-year in 2018. This is attributable to the switch to SIA 380, reclassifications and sales. Energy consumption and emissions fell disproportionately overall, by 16% and 12% respectively. The goal of further reducing energy and emissions intensity was therefore also achieved: energy inten sity (2018: 137 kWh/m²) was 9% lower than in 2017, while emissions intensity was down 4% (2018: 22 kgCO2eq/m²).
