SUSTAINABLE & EFFICIENT OPERATIONS ESR strongly believes that elevating environmental performance and improving efficiency is critical to the preservation of natural resources and success of the business. Therefore, our focus on investment and implementation of resource-efficient technologies such as mechanical, electrical and plumbing systems and equipment will optimise our buildings’ energy and water use efficiencies. For those managed assets for which ESR is not the original developer, we also take actions to develop or enhance sustainable features to make the buildings greener. There are four significant attributes that we emphasise in our property portfolio as follows: GREENHOUSE GAS EMISSIONS REDUCTION WATER CONSERVATION SUSTAINABLE MATERIALS BUILT TO LAST • Replacing traditional lighting with energy saving alternatives (i.e. LEDs) • Setting lighting control functions in 90% or more of the individual occupant spaces • Using renewable grids with low carbon emissions, if available • Enabling thermal temperature tailoring in 50% or more of individual occupant spaces • Using onsite renewable energy sources such as biofuels, geothermal, hydro, solar/ photovoltaic or wind • Using self-contained hot water systems that achieve 85% or more efficiency • Using natural sunlight to illuminate the building space (achieve 75% or more lighting in regularly occupied floor area) • Installing smart subsurface irrigation systems with soil moisture sensors that drip feed native plants • Managing cooling tower water to optimise recirculation cycles and reduce water consumption • Using recycled water like treated wastewater and stormwater for non-potable applications • Obtaining green ratings for our amenities such as the WaterSense label (US EPA) and LEEDv4 (fixture and fitting code requirements) • Partnering with local suppliers to minimise carbon footprint and support local businesses • Using recycled content in our construction sites and office spaces • Acquiring materials with green certifications such as Carpet and Rug Institute Green Label, FloorScore and legally harvested timber • Reducing the use of ambient concentrations of chemical contaminants • Creating kerbs for protection of external walls in delivery and vehicle drop-off areas • Applying impact protection features on doors and corridors to reduce wear and tear • Installing hard-wearing floors to allow for easy maintenance and washing • Constructing robust external walls that apply to up to two metres from the ground ENVIRONMENTAL, SOCIAL AND GOVERNANCE REPORT 2021 24 PILLAR 2: PROPERTY PORTFOLIO
