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. To that end, Post Oak Central’s three LEED Gold certified buildings play a major role in 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.

The company recognizes that promoting workplace sustainability involves more than just improving energy and water efficiency, also placing a keen focus on optimizing the health and well-being of building occupants across its portfolio. At Post Oak Central that includes annual air quality testing, a green cleaning policy, integrated pest management, green tenant guide, bi-annual sustainability newsletter and e-waste recycling, a program that has seen annual participation result in collections as high as 50,000 pounds (almost 25 tons).

The 17-acre Post Oak Central campus boasts beautifully landscaped grounds that provide an easy connection to the Uptown District’s newly enhanced, pedestrian-oriented streetscapes with the new METRORapid Silver Line transit lane. Additionally, the mixed-use development’s popular green space was designed for communal gathering, events and the appreciation of nature – set against the backdrop of one of Houston’s most dynamic and bustling urban neighborhoods. It also benefits from a location just a short walk from nearly 1,500-acre Memorial Park with amenities ranging from golf and swimming to tennis and fitness, along with some of the city’s favorite trails and waterways for hiking, biking and kayaking.

Annual Sustainability Report

Sustainability at Post Oak Central

  • 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.

  • 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.

    By obtaining the UL Verified Healthy Building Mark, we have demonstrated a commitment to the health and well-being of our building’s occupants.

Our validation will help give both manufacturers and consumers peace of mind.
