When it comes to making your building more sustainable, you have a wealth of options and resources. Many building owners and managers start by replacing lightbulbs with energy-efficient options like LEDs or CFLs. You could retrofit your HVAC system with smarter sensing and controls, for even greater energy savings impact and overall ROI. And, you could go longer-term and structural – adding solar panels, replacing windows, or even redesigning your building from the ground up. Every step matters – but as a building owner, you want to be able to quantify those changes. That's why we've made a list of certification programs which help score and benchmark your building for sustainability, making it easier to qualify for energy rebates, keep track of your improvements and advertise your building to prospective tenants.
