Glass Buildings: The Energy Challenge
Posted April 06, 2009
The vitreous high-rise tower is an icon of contemporary urban architecture. From a sustainability perspective, however, building experts and climate advocates are raising concerns about the energy performance of glassy transparent façades. New York City is weighing greener building code recommendations as the city—and the world—reconsider the built environment in the face climate change.
On March 3, 2009, architects and engineers gathered at the New York Academy of Sciences to examine further the energy aspect of glass buildings. Scott Frank of Jaros, Baum, and Bolles provided background on current energy codes and standards, and how recent glass designs have been able to meet them; Adrian Tuluca of Viridian Energy & Environmental discussed energy modeling for code compliance and how well modeling reflects reality; and Chris Benedict, an architect experienced in designing energy-efficient building envelopes, demonstrated calculations used to quantify a design's projected energy performance.

Architecture and Energy Limited/Chris Benedict, RA
An architecture firm specializing in holistic building design yielding, safe, healthy and comfortable, energy efficient buildings.
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) publishes voluntary consensus standards professionally concerned with refrigeration processes and the design and maintenance of indoor environments. ASHRAE Standard 90.1-2007 is the most current "Energy Standard for Buildings Except Low-Rise Residential Buildings" applicable to construction with glass façades. The 2005 Radiant Time Series (RTS) Method Load Calculation Spreadsheets are intended as an educational tool both for the student and for the experienced engineer wishing to explore the new RTS method.

Adrian Tuluca, RA, LEED AP
Adrian Tuluca, Registered Architect and LEED Accredited Professional, is the Principal of Viridian Energy & Environmental, LLC. He has a Master of Architecture from the Institute of Architecture in Bucharest, and a Master of Science in Architecture Technology from Columbia University. He has been performing energy and heat flow analyses for over 20 years. He also did testing and monitoring of energy use in both low rise and high-rise buildings. Adrian led the Building Envelope Systems committee of ASHRAE for several years, was a member of several committees performing testing on building envelopes, and contributed to the ASHRAE Handbook of Fundamentals.
Chris Benedict, RA
The office of Chris Benedict provides architectural services for commercial and residential buildings. She is known for designing elegant holistic solutions to building systems. She has recently completed four new construction residential buildings with 104 apartments. These new buildings each use significantly less energy than typical apartment buildings of the same size, but cost the same to build. She is currently designing a green hotel to start construction in 2008 and two new green apartment buildings in Brooklyn to start construction in 2009.
Benedict is chairman of the Building Enclosure Council of New York (BEC-NY), an AIA sub-committee and the home of Building Science in New York City. She is on the faculty of the Pratt Institute and is a member of the Passive House Alliance and the Mayor's Taskforce for "Greening the Codes."
