Building for the New Economy 19 SUSTAINABLE AND EFFICIENT SOLUTIONS Investing in technologies that improve efficiency and environmental performance are good for the planet as well as our bottom line. Mechanical, electrical and plumbing systems and equipment play a vital role in optimising our buildings’ energy and water use. We implement new construction projects and refurbishments with resource-efficient technology and responsibly sourced materials that will reduce their lifetime ecological impact. Even when we are not the original developer of our managed assets, we strive to enhance their environmental performance through investment in appropriate technological solutions. In Singapore, for example, traditional light fittings have been replaced with energy-saving LEDs in 80% of directly managed properties.
