The new Exhibit Staging Center is open now! 

The Greenest Building in the Most Unexpected Space

With block wall masonry, a flat roof and no windows, the City of Pittsburgh’s former public works building is a typical industrial facility of the 1960s — but it’s not the kind of building most would associate with sustainable design. In 2019, Phipps adapted this structure into its Exhibit Staging Center (ESC) with a dynamic, modernized design and the ambitious goal of achieving three of the world’s most rigorous building standards:

  • Living Building Challenge
  • LEED® Platinum
  • WELL Platinum

The health and well-being of all of our staff is important, which is why the ESC continues to be a space for labor workers and grounds crew, pushing the boundaries of existing standards. In addition to space for prop creation, the ESC features a yoga studio, fitness center and meditation room to encourage the mental and physical wellness of employees.
 

Behind the Sustainable Scenes

To enhance the guest experience, the ESC is open to visitors for a unique behind-the-scenes look at the Conservatory’s past and future flower shows. Guests can enter a vestibule to view future display props being constructed. An adjacent window looks into the exhibit archive room where statuary, topiaries, props and more from past shows are displayed.


 

Standards of Excellence

The ESC aims to achieve LEED Platinum, WELL Platinum and Living Building Challenge certifications. Upon successful completion of the Living Building Challenge’s one-year performance period, Phipps will have three Living and Petal Certified Buildings on its site, each showcasing a different construction type: new (CSL), modular (Nature Lab) and existing (ESC). 
 

Sustainable Features

Site

  • The Exhibit Staging Center lies on a remediated brownfield in the City of Pittsburgh. Phipps has restored the site as a safe environment for people, plants and animals.

Water

  • The lagoon adjacent to the ESC is used to store rainwater and replicate the natural treatment processes of marshes and wetlands on site.
  • Chemical-free sanitary water is recycled treated through a constructed wetland that uses natural plants and microbes, as well as sand filters and UV lights.

Energy

  • Using geothermal wells buried deep into the ground, the building is able to efficiently heat and cool by harnessing the natural energy from the earth’s consistent 55-degree internal temperature. 
  • The roof of the ESC is home to photovoltaic solar panels, which capture the sun’s energy to convert to electricity.
  • To avoid energy waste, a battery stores power and can be used to power the facility.
  • To minimize the use of harsh overhead lights, windows are placed amply and strategically around the building for the use of daylighting. NanaWalls are also used to increase sunlight and air flow on warm days.

The DC Difference

Direct current (DC) electricity is the form of electricity collected by solar panels and stored by their batteries, but most American buildings use alternating current (AC). In conventional settings, a device called a solar inverter converts the DC electricity from solar panels into AC, wasting 10 – 15% of solar energy in the process of process of converting to AC and then back to DC again to power LED light bulbs. The ESC breaks this wasteful convention by using direct DC from the solar panels and batteries to all of the lights in the building directly. That means the entire lighting system for this building could run on a single 20-amp circuit. 


Materials

  • The use of Declare label products, along with the avoidance of Living Building Red List materials, means the building is free from many of the toxic chemicals typically found in building materials.
  • Black locust lumber, a native species with a very hard wood and no need for pressure treatment, was sourced to use on the deck and an interior wall.
  • Sandstone used for the project was sourced locally from quarries in the area.
     

Beauty

  • green roof over the vestibule helps to manage stormwater. 
  • The exterior is made out of corten steel, which naturally rusts to reveal the weathering of time. 
  • Imprints of leaves and horseshoes in the concrete pay tribute to the history and natural connection to the site. 
  • Biophilic design elements and art celebrating the bonds between humans and nature add to the healthy impacts of the building on occupants and guests. 
  • Along one side of the ESC, a vegetative living wall enhances the building’s biophilic connection.

Additional Features

  • Windows have an automatic feature to open when sensors detect air quality is good outside. 
  • The public can view indoor and outdoor air quality in real time with the use of an air quality dashboard.
  • Indicator lights on manual windows allow occupants to know whether the air quality is satisfactory to open. 
  • To accommodate the diverse uses of the space, sound attenuation elements were installed in walls. 
  • Radiant flooring is used throughout the facility to ensure temperature stability and comfort of building occupants.
  • A compost site behind the existing Nature Lab collects matter such as leaves and organic waste.
