Reflections on half a century of building the future, from the inside out.
Engineering the infrastructure upgrades to one of the most famous landmarks in the United States was a challenging and rewarding professional journey for me.
New York City’s compressed urban footprint and extensive mass transit system make it more sustainable than most American cities. Its greenhouse gas emission level, at 6.5 metric tons per person, is lower than that of 16 of the largest U.S. cities and well below the national average of 19.0.
We have worked on two large NYC energy conservation efforts: managing NYC’s 1980’s Energy Conservation Capital program, the largest of its kind, and our more recent effort to improve the energy performance of NYC’s existing office buildings.
A central cooling plant on a college campus has several quantifiable advantages over decentralized equipment. These include improved efficiency, ability to cycle easily between alternate energy sources, reduced maintenance burden for staff, and long-term capital cost reduction. Often overlooked as a benefit, however, is the improvement to campus aesthetics. This article explores a range of benefits realized by Vassar College after building a central cooling plant to replace distributed cooling equipment.
Built during the golden age of train station construction, Grand Central officially opened in February 1913. It is the visible, above-ground part of a mostly underground complex of tracks, platforms and railroad facilities that stretches on 48 acres from 42nd Street to 57th Street and, at its widest part, from Lexington Avenue to Madison Avenue.
There are many good reasons to replace aging chiller plants in the nineteen-nineties. Unfortunately, very few installations were straight-forward in execution because the designers of the original structures rarely considered the necessity of replacing these machines in the future.
Many of our friends are surprised at the number of challenging projects we work on, so we decided to update you. For this newsletter, we are focusing on some of our landmark projects currently in design.
NYU Medical Center Links Six Chillers: Development of a hybrid system spurred by high demand charges
New York University Medical Center recently completed a unique chiller interconnection project which will save $575,000/year in energy and operating costs and potentially $3.4 million in avoided future chiller capacity construction.
New York City established the New York City Energy Conservation Capital Program to Identify and Implement energy conservation measures in government-owned buildings. Although many problems have arisen from a program of this magnitude, overall the program has been a success.
The DOE-2 computer program has been used extensively in recent years for modeling energy conservation measures (ECMs). Due to the complex and timeconsuming data gathering process demanded by the program, use of the model is most appropriate for complicated buildings.
Turn-of-the-century apartment cooperative is New York’s first to apply solar panels for service water heating.
