In 2019, our global energy use (for the provision of small power, heating and cooling) across our occupied estate was 91,921 MWh. We continue to apply energy reduction programmes across our estate.
In Asia, we completed seven site assessments as part of our work towards achieving our target to conduct energy assessments of our top 20 highest energy-consuming sites. This brings the total number of sites assessed to 13 and the remaining seven site inspections are scheduled for 2020. We have now completed assessments on facilities in Hong Kong, Indonesia, Malaysia, the Philippines, Singapore, Taiwan, Thailand and Vietnam. Through this process we have identified over 70 initiatives with potential savings of 4.8 GWh, or around 13 per cent of the energy consumption for these top 20 offices. The savings opportunities will continue to build as we progress with the remaining assessments in 2020. After the assessment of our Hong Kong Gateway office, the local business implemented a range of measures such as switching off lighting, adjusting temperature set points and implementing an out-of-hours IT shutdown, yielding an instant energy and associated carbon emission reduction of 7 per cent. Further measures are being considered for implementation in 2020.
In the US, Jackson continues to reduce energy usage and decrease our carbon footprint. In 2019 Jackson completed a range of projects at our Corporate Way campus in Lansing, including:
- Installing high-efficiency rooftop units with CO2 sensors to replace older equipment
- Installing new 97 per cent-efficient condensing hot water heaters to replace two 80 per cent-efficiency hot water heaters
- Installing an energy recovery ventilation unit to replace two 10Kw electric heat make-up air units in the printing facilities in the Corporate Centre building
- Installing a new dust-collector filtration system to reduce exhaust and recover energy in printing facilities, while also improving air quality.
