Financial Analysis

For new building construction and upgrades within existing buildings, Donnelly can provide you with expert financial analysis that allows you to consider the lifecycle cost of your HVAC equipment. This report factors in eligibility for tax rebates and incentives, as well as annual operating costs, from the “base” unit to the most efficient. Oftentimes these reports reveal that the lowest first-cost unit is almost always the most expensive to own. Above all else, you will get a clear picture of where and how you can save money today and over time.

LEED, Sustainability & Green Construction

At the forefront of building sustainability and green construction, Donnelly has worked on many high-profile LEED Platinum-Certified projects, most significantly the Bank of America Tower at One Bryant Park – the first commercial high-rise ever to achieve this distinction. Donnelly has certified LEED experts and CEMs on staff as well to help you with your sustainability and green building projects.
