What is going Green? Is it replacing a boiler for $250,000 or replacing the tubes for $45,000 and adding 8-11 more years to the systems lifecycle? How else can the "saved" $200,000 be invested to achieve a greener, healthier, more efficient system...overall? What about investing 200K in an EMS system that will further reduce energy consumption by 12-15% AND also be eligible for a Con Edison rebate of 50%...100K? Now you still have 100K to invest....what about controls and lighting upgrades to all laundry rooms and common areas? Another investment that comes with rebates.
There are many ways to invest in "green" that will absolutely spread the impact of the initial investment...all it takes is patience, a board willing to listen and a progressive and intelligent property management team.
