Donnelly Mechanical Corp. has joined the New York City Carbon Challenge with its headquarters in Queens Village pledging to match the city's 30X17 energy efficiency plan to reduce municipal greenhouse gas (GHG) emissions 30% by 2017. Donnelly Mechanical, which encourages high efficiency through its HVAC service, maintenance and construction services, is committed to leading by example through the Carbon Challenge. Though the goal of 30% GHG reduction may be ambitious for most of the buildings signed up for the Carbon Challenge, Donnelly Mechanical specializes in reducing energy consumption for the firm's clients with the use of cutting-edge technology and the experience of in-house energy experts. Through energy audits, high-efficiency equipment replacements and preventative system maintenance, Donnelly Mechanical is well known for its triumphs in drastically reducing the energy expenses of its clients, typically saving clients up to 50% of their energy bills. In addition to maximizing the energy-efficiency of clients' buildings throughout the city, Donnelly Mechanical has previously been recognized for its efficient headquarters with the Energy Star rating, certifying that the building performs in the top 25% of similar facilities nationwide. Donnelly Mechanical will increase its efforts to reduce the municipal GHG emissions of its headquarters as part of its ongoing dedication to increasing the sustainability of the city. Dan Donnelly, CEO of the firm, said, "With 75% of New York City's greenhouse gas emissions coming from buildings, it is crucial that Donnelly Mechanical does its part in reducing energy consumption in our own building. In participating in the Carbon Challenge, we will demonstrate how easy sustainability can be when you have proper mechanical systems and maintenance." With PlaNYC, New York City's Office of Long-Term Planning and Sustainability set an ambitious goal to reduce citywide GHG emissions 30% by the year 2030 with the help of partners from the private sector. Since 2007, 17 of New York City's leading universities, the 11 largest hospital organizations, 12 global companies, and 10 residential management firms have accepted the Carbon Challenge, pledging to match City government's 30X17 goal and reduce building-based emissions by 30% or more in just ten years.
