Built in 1970, the 64-story U.S. Steel Tower in the heart of downtown Pittsburgh ranks as the 7th largest high-rise office building in the U.S. by square footage. Through a series of retrofits to improve its energy efficiency, the iconic skyscraper recently achieved ENERGY STAR certification.
“In the past decade, Pittsburgh has become known worldwide as an innovative, sustainable community that is focused on efficiency and performance,” said County Executive Rich Fitzgerald. “[This] announcement adds the U.S. Steel Tower to the list of properties, buildings, facilities, and spaces that are focused upon reflecting those characteristics. Congratulations to Winthrop Management on this achievement, and its partners for their cooperation and collaboration in reaching this milestone.”
“Winthrop’s achievement of ENERGY STAR compliance is a great example of the leadership building owners can take in providing transparent and available data,” said Pittsburgh Mayor William Peduto. “The city’s recently passed energy transparency ordinance will help support these energy efficiency activities. We look forward to partnering with property managers like Winthrop to further advance energy efficiency across the city.”
“Achieving ENERGY STAR certification is a tremendous accomplishment and a significant milestone in the storied history of the U.S. Steel Tower,” said Thomas J. Harrington, general manager of the building for Winthrop Management LP. “Designed with a robust infrastructure in an era when energy was inexpensive and energy efficiency not a first priority, this initiative required a major commitment from the building’s ownership, tenants, and several community and business partners. The ENERGY STAR portfolio manager program allowed us to track our progress as we made improvements with the financial assistance of Duquesne Light Company’s Watt Choice program. This is a proud day for Winthrop Management and the U.S. Steel Tower.”
In 2013, Winthrop Management signed the U.S. Steel Tower on to the Pittsburgh 2030 District challenge, a public-private partnership to create a high-performance and energy-efficient building district in downtown Pittsburgh by the year 2030. As part of this challenge, businesses are committing to reduce energy usage to 50 percent below the national average over the next 13 years.
“The U.S. Steel Tower has been a strong Pittsburgh 2030 District Property Partner, actively leading the way for 483 other committed buildings in working towards measurable energy, water, and transportation emissions reductions of 50% below baselines by the year 2030,” said Angelica Ciranni, the Green Building Alliance’s Pittsburgh 2030 District Director. “Quick to share innovative approaches and lessons learned, the U.S. Steel Tower’s property management, facilities staff, and tenants have worked as a team over many years to achieve an ENERGY STAR designation for one of Pittsburgh’s most iconic buildings that demonstrates the region’s leadership in energy conservation.”
With the help of evolveEA, Winthrop Management’s energy efficiency initiatives include:
- Lighting: Installation of highly efficient LEDs in the building’s lobbies and new lighting in the garage.
- VFDs and HVAC upgrades: Variable Frequency Drives and state-of-the-art HVAC technologies.
- Elevator upgrades: A new energy efficient elevator system.
- Tenant engagement: Winthrop and evolveEA collaborated with building tenants to establish a sustainability committee that teaches and encourages eco-friendly behavior among occupants while measuring effectiveness.
- BOMA360: Measures to save energy were first channeled toward achieving certification under a program of the Building Owners and Managers Association and were subsequently leveraged toward achieving ENERGY STAR certification. From a 2010 baseline the U.S. Steel Tower reduced its energy use by 28.5% from 67,397,908 kWh to 48,226,200 kWh, while building occupancy rose from 78% in 2009 to 98% in 2013.
Winthrop Management was able to leverage financial incentives through Act 129, which requires Pennsylvania electric distribution companies to adopt and implement conservation plans that reduce energy demand and consumption within their service territory. Duquesne Light’s Watt Choices program helped Winthrop finance major lighting projects as well as upgrades to the building’s VFDs and HVAC upgrades.
“evolveEA provided education and consulting to Winthrop, helping to map out a strategy for their sustainability initiatives,” said Marc Mondor, evolveEA Principal. ”At the same time, we worked with UPMC, the primary tenant, to improve their office spaces and achieve LEED For Commercial Interiors certifications for nearly one million square feet over the last decade. This two-pronged approach has made the U.S. Steel Tower one of the region’s best performing office buildings. It’s fitting that such an iconic part of Pittsburgh’s skyline will now be identified with the city’s green renaissance and reinvention.”
