Property managers are feeling increased demand for energy management and environmental responsibility from owners, tenants, and the public. Improving energy efficiency lowers maintenance and operation costs, creates comfortable workplaces for tenants, and reduces the carbon footprint of buildings. Toli Sidiropoulos, Energy and Sustainability Manager for AXA Place, shared how a 20 story office building reduced its energy consumption by almost 20% in one year and won an Earth Award from BOMA for its sustainability efforts. Toli’s presentation included an overview of: * the conservation/sustainability plan for AXA Place * the retrofits, upgrades, and initiatives that successfully generated energy savings * the role that energy management systems played in optimizing AXA Place’s energy performance
