Sustainability & Innovation

Our Commitment

Parkway’s sustainability mission is to make a positive and profitable contribution toward a sustainable future by integrating green building practices into all aspects of its business.

Encompassing 11 buildings, the Greenway Plaza portfolio plays a critical role in Parkway’s overall sustainability core values, which include Creating Value Through Sustainability, Investing in Health and Productivity, Demonstrating Efficient Operations and Effective Management, and Building an Equitable Future for Customers and Investors.

All of Greenway Plaza’s buildings are LEED Gold certified, and in 2018, Phoenix Tower received its Energy Star certification for the 20th consecutive year. The iconic property is the only structure in the country that has earned this designation annually since the program was first instituted.

The pedestrian-friendly campus, which incorporates numerous green and gathering spaces, boasts high walkability scores and benefits from a Zagster bike share program with four kiosks. Further highlights include e-waste recycling, annual air quality testing, a green cleaning policy, integrated pest management, plus a green tenant guide and bi-annual sustainability newsletter.

With the goal of optimizing the health and well-being of building occupants, Greenway plaza is home to four fitness facilities, including a state-of-the-art, 80,000-squre-foot Life Time, boutique style membership based Activate Studio in 11 Greenway and Pulse Fitness in The Hub, as well as a recently updated fitness center in Phoenix Tower.

Sustainability at Greenway Plaza

  • Reduce water use intensity by 30%

    Over the past several years, we have upgraded all of the original domestic water fixtures at all of our buildings with low-flow valves and aerators. As a next step, we have begun evaluating opportunities to improve irrigation water efficiency across our Houston portfolio.

  • Decrease energy use intensity by 20%

    Through our short-term and long-term capital plans, we have funded numerous multi-year projects to upgrade major HVAC equipment and overhaul aging central plants across our portfolio. In addition, we have completed major garage and common-area lighting retrofits and installed CO2 sensors and dimmable stairwell lighting at many of our properties.

  • Decrease carbon emissions by 20%

    Our efforts to reduce our greenhouse gas emissions (as measured in MTCO2e) go virtually hand-in-hand with our efforts to reduce energy consumption. However, we also take extra steps to reduce our GHG emissions by upgrading to environmentally preferable refrigerants whenever we upgrade our buildings’ HVAC systems.

  • Reduce sources of waste and increase waste diversion rates to 75%

    All of our properties have had building-wide recycling programs in place for many years. However, in 2017, we began making a major push to further improve our recycling programs and optimize our overall waste management process. To that end, we recently replaced antiquated trash bins with modern trash compactors, we expanded our use of cardboard bailers, and we worked with existing janitorial teams to improve the daily waste collection and recycling processes at each property.

  • A BOMA 360 Performance Building

    The BOMA 360 Performance Program sets the standard worldwide for operational best practices in the commercial real estate industry. For building owners and managers who want to help their properties stand out from the crowd, there is no clearer mark of excellence than achieving the BOMA 360 designation.

    Earning the prestigious BOMA 360 label demonstrates that a building is outperforming the competition across all areas of operations and management.

  • Connectivity is business-critical.

    WiredScore is the global digital connectivity certification system that helps landlords assess, improve, benchmark and promote their buildings and proves that your building has the digital infrastructure that the companies of today rely on, and the companies of tomorrow will be looking for. WiredScore adds demonstrable value to a property, keeping it relevant in the market, showing current and prospective tenants and residents that your building goes above and beyond to meet their connectivity needs.

  • UL Verified Healthy Building for Indoor Environment

    By obtaining the UL Verified Healthy Building Mark, we have demonstrated a commitment to the health and well-being of our building’s occupants. UL Solutions independently validates that products are measuring up to their marketing claims, including recycled content to landfill waste diversion claims. Our validation will help give both manufacturers and consumers peace of mind.
