In addition to these savings, there is a derivative effect from Quantum on the HVAC system energy performance. The dramatically reduced output levels of the lighting system means that less heat load is created by the lights, which means the air conditioning system works less, further reducing energy use in the building.
Hughes says, “total light management represents the single greatest opportunity for energy savings in commercial buildings, whether retrofit or new construction projects.”
One of the most important features of the system is the robust database that collects system performance details continuously. This enables the user to analyze and optimize system performance. Hughes indicates that the data recently evaluated for 2009 shows consistent performance with earlier results. The system began with tremendous results and continues to deliver the same performance now more than two years since start-up.
Average lighting power density for all The New York Times Company space in 2009 was 0.396 watts/sq. ft. Peak lighting power density (the single worst hour of the year for 2009) was 0.76 watts/sq. ft.
Putting this into perspective, Glenn says that this peak represents 40% better performance than the original design. He also presents this data to the design community and challenges them to design the lighting systems to levels well below code because we know it can be accomplished, citing the building’s performance as the evidence. In fact, the American Institute of Architects has taken the stand that for the next decade, architecture should be influenced by evidence-based design.
Hughes says that the story doesn’t end by looking at energy savings alone. Quantum dramatically improved the lighting environment inside The New York Times Building. According to Hughes, assuming a mere 1% increase in productivity (a conservative estimate), from the improved lighting environment, the Quantum system paid for itself in less than a year. He also emphasizes that this value-add goes on year after year.
First published in 1851, The New York Times has long enjoyed pride of place among all news organizations in the United States. The Times is a time-tested institution operating in the American media capital and the most fabled city of the modern world where supremacy is the norm. It’s an organization that understands that what it says and does reverberates across many borders.
It’s no surprise, then, that when the newspaper’s parent company, The New York Times Company, a global media enterprise, decided to build a new headquarters in Manhattan, it eschewed the idea of maintaining a passive role in the project. The company resolved to exercise control at every stage of the project’s design and construction processes, ensuring that the new building accurately represented its corporate culture and values, and reaped real business benefits for the company.
“We desired an interior environment that allowed our employees to be as comfortable as possible and that would reinforce our company’s emphasis on open communication, collaboration and transparency,” said David Thurm, former Sr. Vice President of the Times Company.
To accomplish these objectives, the Times Company hired the world-renowned architect Renzo Piano, along with two major architectural firms, FXFOWLE of New York, and Gensler, headquartered in San Francisco. The Times Company also employed the lighting design services of SBLD Studio of New York.
