Mid-Sized Midtown Office Buildings Earn LEED-EB: OM Certification

Two mid-sized commercial office buildings in Midtown recently earned LEED-EB certification, pushing New York City’s total -EB count to 44 properties.

Entrance to 498 Seventh Avenue

The sustainability consulting firm CodeGreen Solutions recently announced that two George Comfort & Sons-owned office buildings in Midtown have earned LEED for Existing Buildings: Operations & Maintenance (2009) certification from USGBC. The 650,000-square-foot 498 Seventh Avenue and the 900,000-square-foot 200 Madison Avenue were certified Gold and Silver, respectively. By our count, this raises the total number of LEED-EB-rated office buildings in New York City to 44.

200 Madison Avenue

Energy efficiency was a primary focus for CodeGreen in spearheading each tower’s certification efforts. Indeed, both earned Energy Star labels in 2012, and CodeGreen also performed ASHRAE Level 2 Energy Audits and retro-commissioning studies in connection with the certifications. Each building also dropped water consumption by 15 percent over LEED requirements, purchased 62.5 percent green power, and kept an ongoing consumables recycling rate of 50 percent during the -EB: OM performance period. Both properties should now be available in CodeGreen’s neat mobile app, which we noted here at gbNYC+ earlier this year.

The 25-story 498 Seventh Avenue is located between West 35th and 36th Streets and dates from 1920. It was originally designed by Harmin Jablin Architects in a neoclassical style and was once known as the Bates World Building. Current tenants include Mindshare, Modell’s, Liquidnet, and Jones Apparel.

Across town, 200 Madison Avenue’s tenant roster includes Greater New York Mutual Insurance and Rose Associates. That 25-story tower was designed by Warren & Wetmore (Grand Central Station) and has a colorful history, trading hands through the years from the Astor Estate to Marshall Field’s.
