In 1986, this 25-story high-rise began operating the world\u2019s largest off-peak cooling system, which manufactures two million pounds of ice per night\u2014the system is still functional today and it helps cool not only The Mart, but other neighboring buildings, too. After a series of sustainable features, which included a recycling program for paper products, glass, lamps, batteries, aluminum and construction materials in 1991, a voluntary initiative to reduce smoke-forming pollutants and energy consumption that enabled the asset to reduce 264,018 pounds of VOC pollution in 2006, The Merchandise Mart received its first LEED certification to the Silver level in 2007 with assistance from The Delta Institute of Chicago. In 2013, it successfully handled the six key areas within the LEED-EB Operations and Maintenance certification review, including sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, and innovations in operations and was awarded LEED Gold.<\/p>\n<p>Merchandise Mart Properties (MMPI), a wholly-owned subsidiary of Vornado Realty Trust and the owner of the asset, continued to invest in upgrades to the property, including erosion control and a landscape plan. Additionally, The Mart utilizes drought-tolerant plans to reduce water consumption, and employs an integrated pest-management plan to reduce harmful toxins that pollute air and water. The building also provides multiple alternative transportation options, including access to public transportation, bicycle storage and on-site shower facilities for riders, and an I-GO hybrid car-sharing program, available 24\/7 to Mart staff and tenants. Another building-wide commitment assumed by the owners of the property was to utilize natural light where possible, thus MMPI converted common-area lighting to CFL and LED, retrofitted all exit lights to be more energy efficient and utilizes split lighting levels and light circuits to reduce light usage in the loading dock area.<\/p>\n<p><strong>One World Trade Center \u2013 LEED Gold<\/strong><\/p>\n<div id=\"attachment_1004265851\" style=\"width: 250px\" class=\"wp-caption alignright\"><a href=\"https:\/\/www.commercialsearch.com\/news\/wp-content\/uploads\/sites\/46\/2018\/09\/One-World-Trade-Center-1.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-1004265851\" data-attachment-id=\"1004265851\" data-permalink=\"https:\/\/www.commercialsearch.com\/news\/top-largest-leed-certified-office-buildings-in-the-u-s\/one-world-trade-center-3\/\" data-orig-file=\"https:\/\/www.commercialsearch.com\/news\/wp-content\/uploads\/sites\/46\/2018\/09\/One-World-Trade-Center-1.jpg\" data-orig-size=\"410,512\" data-comments-opened=\"0\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"One World Trade Center\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;One World Trade Center&lt;\/p&gt;\n\" data-large-file=\"https:\/\/www.commercialsearch.com\/news\/wp-content\/uploads\/sites\/46\/2018\/09\/One-World-Trade-Center-1.jpg?w=410\" class=\"wp-image-1004265851 size-medium\" src=\"https:\/\/www.commercialsearch.com\/news\/wp-content\/uploads\/sites\/46\/2018\/09\/One-World-Trade-Center-1.jpg\" alt=\"\" width=\"240\" height=\"300\" srcset=\"https:\/\/www.commercialsearch.com\/news\/wp-content\/uploads\/sites\/46\/2018\/09\/One-World-Trade-Center-1.jpg 410w, https:\/\/www.commercialsearch.com\/news\/wp-content\/uploads\/sites\/46\/2018\/09\/One-World-Trade-Center-1.jpg?resize=240,300 240w\" sizes=\"auto, (max-width: 240px) 100vw, 240px\" \/><\/a><p id=\"caption-attachment-1004265851\" class=\"wp-caption-text\">One World Trade Center<\/p><\/div>\n<p>Owned by the Port Authority of New York &amp; New Jersey, the tallest building in the western hemisphere received its LEED Gold certification in 2016.

The glass is coated to allow natural light reach more than 90 percent of the building\u2019s office areas and reduce artificial lighting. To optimize energy use and indoor air quality, the property uses a building management system comprising thousands of sensors throughout the structure. Stormwater runoff is captured and stored in three retention tanks and is used for cooling and irrigation, reducing the building\u2019s water usage by 41 percent. More than 40 percent of the materials used in construction were recycled, including gypsum boards, ceiling tiles and glass. Also, more than 87 percent of construction waste from the project was diverted from landfill.

The certification followed the creation and implementation of a new process for economically justified energy efficient retrofits in the existing built environment, created by a team of Clinton Climate Initiative, Johnson Controls, Jones Lang LaSalle and the Rocky Mountain Institute. The analytical model is non-proprietary and open-source, and has been replicated for other properties around the world.<\/p>\n<p>The retrofit reduced the building\u2019s energy consumption by more than 38 percent and is said to save $4.4 million in energy costs annually and reduce carbon emissions by about 105,000 metric tons over 15 years. In January 2011, Anthony Malkin, chairman &amp; CEO of Empire State Realty Trust\u2014the skyscraper\u2019s owner\u2014agreed to buy carbon offsets totaling 55 million kilowatt hours per year of renewable energy, turning the Empire State Building carbon-neutral. For the 2.8 million-square-foot asset to achieve LEED Gold, it has undergone a series of improvements including: installation of ultra low-flow fixtures in the building\u2019s restrooms, use of green cleaning supplies and pest control products, recycling of tenant waste and construction debris, use of recycled paper products, use of recycled content carpets, low off-gassing wall coverings, paints and adhesives, and a tenant engagement program, including submetering, a tenant energy management system and mandatory green requirements in lease agreements.

The 72-story asset was designed by architect Fumihiko Maki to meet LEED-Gold standards. Vidaris developed the overall green\/LEED thrust for four of Silverstein\u2019s towers of the World Trade Center complex, including the one in question.<\/p>\n<p>For Tower 4, Vidaris preformed a three-dimensional heat-flow analysis of the building envelope, intended to highlight means of reducing the potential for moisture condensation. The 2.5 million-square-foot project is 100 percent powered by renewable sources, including wind, solar and hydroelectric power. It uses 20 percent less electricity than a conventional office building thanks to high-performance elevators, heating and cooling systems; it also uses 30 percent less water thanks to rain water collection and low-flow fixtures. In addition, insulated windows reduce the need for artificial lighting and air-conditioning. A preferred parking program for fuel-efficient vehicles was implemented as part of the LEED requirements. For the construction of the tower, 50 percent of the wood used was sustainably harvested and the construction process used significant amounts of recycled material.<\/p>\n<p><em>Images courtesy of Yardi Matrix<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>When combining size and sustainability features in office properties across the U.S., San Antonio, New York and Chicago hold the top spots.<\/p>\n","protected":false},"author":237,"featured_media":1004266562,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[1491,21808,22251,41288,23891,1600,21742,21747,1607,21786],"tags":[39329,37228,32779,36749,34035,32957,32777],"class_list":["post-1004265842","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-chicago","category-featured","category-in-focus","category-rc-listicles","category-national","category-new-york","category-latest","category-office","category-san-antonio","category-sustainability","tag-topofthelist","tag-empire-state-building","tag-leed","tag-one-world-trade-center","tag-silverstein-properties","tag-usaa-real-estate-company","tag-usgbc"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.4 (Yoast SEO v24.6) -
