Sustainability reporting: Mirvac, Stockland, Investa and Westfield

Mirvac recently released its 2014 sustainability report, with some big environmental gains announced. We thought it was a good chance to have a look at these achievements, and see what progress other real estate companies have made over the year, too. If your company has some impressive achievements over the past financial year, get in touch and we’ll add them.

Mirvac

Mirvac’s sustainability report for 2014, The year that changed everything, shows the progress the company has made towards its long-term sustainability strategy released in 2013, “This changes everything”, part of which is to be net positive by 2030 –generating more energy and water than is consumed, and zero waste.

On the environmental performance front, this year Mirvac said it had raised its average office portfolio NABERS Energy rating to 4.9 stars, up from around 4.5 stars last year.

While total greenhouse gas emissions have risen, thanks to new acquisitions, carbon intensity has decreased by 10.6 per cent (17.7 per cent for office and industrial, though just 2.7 per cent for retail). The target for 2018 is a 20 per cent reduction in intensity, with the net positive goal slated for 2030.

On energy, total energy use was 75,500 megawatt-hours, equivalent to around 52MW of installed renewables. In the report Mirvac provides an indicative pathway to net zero energy, which could see the company reduce consumption by 40 per cent by 2030, with 35MW of renewables installed. So far, however, only 80kW of solar PV has been installed on its 23 Furzer Street building in Canberra.

For water, the plan is to reduce potable water consumption from 883,012 kilolitres to 750,560KL by 2018, with 15 per cent non-potable. A pathway to zero water by 2030 would be a 50 per cent improvement in efficiency on FY14, as well as 55 per cent rainwater tanks residential, 16 per cent rainwater tanks to commercial, 11 per cent greywater/blackwater systems, 11 per cent artificial lakes, and seven per cent connection to district recycled water systems.

On waste, Mirvac is recycling 96 per cent of construction waste and 39 per cent of operational waste. There’s a goal of 100 per cent construction waste recycling on one project by 2018, and a 75 per cent operational waste recycling goal by 2018.

Mirvac has also committed to life cycle assessment on all new projects from June 2014, and a goal to prequalify 50 per cent of its supply chain on sustainable practices by 2015.

On the agenda for Mirvac to achieve by 2018: installing one megawatt of renewable energy; creating a One Planet Living community; and increasing water capture and recycling to 15 per cent.

Stockland

Stockland has given itself a target of 4.5 star NABERS across its office portfolio, and has achieved a 4.47 star average in FY14.

In retail, the company currently has NABERS energy ratings on 12 shopping centres in NSW and QLD, and will rate the remainder of eligible centres in the portfolio by the end of FY15. The NABERS target across all commercial office portfolio is 4.5 stars by 2017.

Total purchased electricity went down from 114,261,122kWh in 2013 to 112,687,960kWh in 2014.

This year the company exceeded its FY14 target of reducing carbon intensity by 20 per cent, with an average reduction of 29 per cent across the office and retail portfolio.

On the agenda: getting a Green Star –Communities rating for its Caloundra South development, a 40 per cent reduction in energy use for residential and retirement living compared to regional averages, three per cent renewables for retail.

On water, intensity increased, which Stockland put down to a shift towards more water intensive food retailing, gyms, car washes, and so forth. It has achieved a 4 star NABERS water rating across the portfolio, and are targeting a 4.5 star rating for its office holdings.

Stockland was unable to access alternate water sources for its Marsden Park development in Sydney but says it is exploring opportunities for Caloundra South and Calleya.

On the agenda: a five per cent reduction in potable water intensity for commercial, a 40 per cent reduction in portable water use for residential and a 20 per cent reduction in water use in retirement.

On waste, Stockland had 85 per cent of construction waste diverted from landfill, down from 90 per cent in 2013. Regarding operational waste, 31 per cent of retail waste was diverted, and 53 per cent of office waste. Stockland is in future committing to 96 per cent construction waste diverted from landfill, 36 per cent of retail waste diverted, and 70 per cent of office waste diverted.

Investa

Investa’s annual review FY14 gives an insight into sustainability performance.

NABERS Energy ratings are at 4.2 stars, equal to the performance in 2013.

Greenhouse gas intensity has gone from 86kg of CO2-e/sq m in 2013 to 78kg in FY14, a close to 10 per cent reduction.

Electricity intensity has decreased from 88kWh/square metre to 84kWh/sq m. This represents a 19 per cent decrease since 2011.

Gas intensity is also down from 99MJ/sq m in 2013 to 77MJ/sq m. This is a 42 per cent decrease since 2011.

On water, the average NABERS Water rating is 3.7 stars, the same as in 2013. Water intensity has gone from 792L/sq m in 2013 to 692L/sq m. There has been an 18 per cent decrease in intensity since 2011.

On waste, 46 per cent of office waste has been recycled, up from 34 per cent in 2013.

Westfield

Westfield’s 2014 sustainability report said total energy consumption had decreased by two per cent in 2013 compared to 2012, thanks to improved energy efficiency in each of the countries it operates in.

In Australia, even though the company added three more centres, electricity consumption decreased by three per cent due to energy efficiency measures including IELVS, variable speed drives, and electrical sub-metering for airconditioning and lighting.

Westfield has committed to capping electricity use at 2011 levels through to 2015.

There was a five per cent increase in total carbon emissions and a four per cent decrease in water consumption.

On waste, there was a 283 per cent increase in non-hazardous waste, put down to the excavation and demolition waste from the major renovation projects at Garden City and Miranda in Australia. It said 42 per cent of non-hazardous waste was recycled, recovered or composted.
