LEED Certification
As environmental issues intensify, businesses are beginning to covet LEED certification for their buildings more and more. Green buildings save money on energy costs and attract new tenants. The LEED certification point system is very simple – some would argue that it’s so simple, it’s flawed. Each eco-friendly feature gets one point, no matter how significant in terms of sustainability. (For example, a bike rack gets one point, as does photovoltaic panels and waterless urinals.) The LEED certification system consists of four levels – certified (at least 26 of 69 points), silver, gold and platinum (at least 52 of 69 points.) Big cities in New York and California make up most of the trend, though many midwesterners are also jumping on board. Below is a list of some of the greenest buildings in the U.S. Most of these have achieved at least a Gold LEED rating.
Green Buildings
11 Times Square – New York, NY
This building’s center, a 600-foot-high concrete core, serves as its command center with extra-wide stairways, elevators and utility risers. Air intake monitoring and filtration, water collection, and sustainable construction justify a Gold LEED rating for 11 Times Square.
Adobe Systems Towers – San Jose, CA
Adobe Systems is the first corporation to have three LEED Platinum rated buildings. The East and West towers were renovated in 2001 to reduce energy usage and feature an irrigation system that’s linked to local weather stations and automatically adjusts to real-time weather conditions. The third building – Almaden Tower – was built in 2003. All three towers received Platinum LEED certification in 2006. Bathrooms feature waterless urinals, automatic flush valves, faucets, soap dispensers and paper towel dispensers which minimize waste and improve sanitation. Adobe utilizes an Intelligent Building Interface System (IBIS), which allows staff to monitor and operate various building controls, such as lighting or temperature adjustments in one or multiple towers, within a single computer program.
Alberici Corporate Headquarters – Overland, MO
In 2004, Alberici converted their 50-year-old manufacturing facility into a sustainable corporate headquarters building. Renovations include features such as an outdoor courtyard; two retention ponds to prevent stormwater runoff; a rainwater catchment system; a raised floor and natural ventilation system and a wind turbine that generates 20 percent of the building’s total energy needs. In addition to “going green,” Alberici formed Vertegy – a company that focuses on building and renovating to green standards.
Audubon Center – Los Angeles, CA
This was the first Platinum LEED Certified building in the nation and functions entirely off of the electrical grid, via on-site solar systems. The Audubon Center was constructed with over 25 percent locally-harvested and over 50 percent locally-manufactured materials and was also awarded points for water conservation.
Bank of America Tower at One Bryant Park – New York, NY
This 54-story building is 1,200 feet tall, making it the second tallest building in New York (next to the Empire State Building), housing 2.1 million square feet of office space. Its $1 billion construction was done with renewable, recycled raw materials within 500 miles of New York. The floor to ceiling windows maximize heat from the sun and flood the building with natural light, boosting worker efficiency. LED lighting and perimeter daylight dimming also reduce electricity. A 5.1 megawatt cogeneration plant produces about 70 percent of the building’s energy needs. Climate control is achieved by a groundwater heat exchanger that makes ice to cool the building, supplementing the air conditioning system. Waste and rainwater are reused and waterless urinals and low-flow fixtures save water. An air filtration system removes 95 percent of particulates and volatile organic compounds (VOCs), so that the air vented back into the city is cleaner than the intake, making the building, essentially, one giant air filter. Overall, the building reduces energy consumption and water usage by 50 percent and produces net zero carbon dioxide emissions. It is the first skyscraper of its kind to receive a LEED Platinum rating.
Banner Bank Building – Boise, ID
This is the first building in Idaho to receive a LEED Platinum rating. The Banner Bank building collects storm water from its surrounding seven acres and reuses it in its sewage system. Other “green features” include: individual computer controls instead of light switches; a biodiesel fuel backup generator; under floor air distribution with evaporative pre-cooling; geothermal heat system; convenient location near public transportation access; indoor bicycle storage; individual shower rooms; drought-tolerant vegetation; automated irrigation system with motion sensors; water reclamation system and conserving water fixtures. The building was constructed using locally-sourced and 40 percent recycled materials.
California Department of Education Building – Sacramento, CA
The LEED Platinum Certification given to the California Department of Education building marks the first of this honor awarded to a state-owned office. The building features a highly energy efficient heating and cooling system and applicances. After the building was retrofitted to meet green standards, Governor Arnold Schwarzenegger issued an executive order for a 20 percent energy reduction in state-owned buildings by 2015.
California Environmental Protection Agency Headquarters – Sacramento, CA
This 25-story office tower has a LEED Platinum rating with a building design that maximizes natural day light and perimeter light sensors that automatically dim the lights inside when the sun shines in brightly. Other features include photovoltaic panels on the roof, low-flow toilets, zero-VOC paints throughout the building’s interior and fan rooms on each floor that can flush in fresh outside air on command. The building composts 10 tons of cafeteria waste a year, saving $10,000.

The Empire State Building – New York, NY
After a $120 million renovation, the Empire State Building joins the ranks among the long list of buildings that have “gone green” and sought LEED Platinum certification to obtain more tenants during the economic recession. The improvements include retrofitting all 6,500 windows for added insulation and upgrading the lighting, cold water and ventilation systems.
Greenway Self Park – Chicago, IL
As Chicago’s first eco-friendly parking garage, this 11-story, 15,000 square-foot unit houses 725 individual parking spaces, along with bike racks, plug-in stations for electric vehicles and spaces for car-sharing services. The entire structure is powered by a series of six wind turbines requiring winds travelling at 2 miles per hour to provide electricity for its exterior lighting. The green roof provides a solution for the problems of urban heat and rainwater runoff.
Hearst Tower – New York, NY
The Hearst Tower has a host of features that contribute to it’s gold LEED rating, including low-emitting glass, light sensors to control the amount of artificial light used based on the amount of natural light available from outside, high-efficiency HVAC systems, Energy Star appliances, and the use of outside air for cooling and ventilation during 75 percent of the year. Rainwater collection and reuse provides about half of the watering needs while also humidifying and chilling the 10-story atrium as necessary. Low-vapor and low-toxicity paints are used on walls and concrete surfaces, and furnishings are formaldehyde-free. Floors and ceilings were manufactured with recycled content and wood from sustainable forests.
Inland Empire Utilities Agency Office – Chino, CA
IEUA was constructed with recycled building materials both on its interior and exterior surfaces. Solar roof panels produce 50 percent of the building’s energy. The use of recycled water and high-efficiency plumbing, along with the planting of native, drought-tolerant trees, shrubs and bushes throughout the landscape, reduces water consumption significantly. Beyond sustainable construction, the office encourages green practices by offering a 9/80 or 4/10 work schedule to employees, providing bike racks and vehicle charging stations and encouraging participation in a rideshare program.
