Sustainability Statistics

LEED Platinum Certification

Land

  • The project redevelops a degraded downtown building site, conserving healthy planting while repairing the damaged. With a new “front yard” and building façade, Leland Federal took on an entirely new identity. 
  • The projects site has 77 percent open space, approximately 3.6x the building footprint.

Planting

  • 58 trees planted on-site, including two native species Water Oak and Winged Elm.
  • 45 percent of the hardscape is shaded by the tree canopy.
  • Fertilizer and pesticides were minimized.
  • Annual planting was avoided.
  • Low water usage plants were used on-site.

Water

  • The planting design offered a 76 percent water usage reduction. The remaining 24 percent of water will derive from a cistern, enabling 100 percent of water to come from a non-potable source.
  • 14,489 square feet of permeable surface.
  • Trees have the potential for intercepting 29,000 gallons of water which is the equivalent to the water usage for 29 American residents for one day.*
  • Green roofs are installed to reduce the heat island effect, absorb storm water and provide enjoyment to the users. 
  • A 15,000-gallon tank holds water from the cooling tower blowdown (4,000 gallons per day) and air handlers (1500 gallons per day).
  • The landscape needs approximately 14,300 gallons of water weekly,

Carbon, Energy + Air

  • The project uses regional materials.
  • The trees sequester 6,960 pounds of carbon annually, which offsets nearly one car per year.**

Social

  • The project supports alternative modes of transportation, with bus access and bike parking.
  • The project provides optimum site accessibility, safety and wayfinding.

* The tree average for water interception is 500 gallons. American’s use an average of 100 gallons of water per day (EPA’s water trivia facts) 

**120 pounds of CO2 per tree annually (This number is based on an average from the National Tree Benefits Calculator) One car produces an average of 8,320 pounds of CO2 per year. (The Code of Federal Regulations - 40 CFR 600.113)

GT Mickey Leland Federal Building

The renovation of the GT “Mickey” Leland Federal Building and Plaza significantly improved the energy performance and sustainability of the building and landscape and provided a much needed improvement to the quality of the spaces. The project is LEED Platinum Certified and was funded as part of the American Reinvestment and Recovery Act of 2009.

The new pedestrian-friendly plaza helps create a memorable identity, offers a secure environment, and provides an inviting outdoor amenity for tenants and visitors.

A sweeping promenade from the northeast to the southeast corners serves as both the primary circulation into the building and generative framework of the plaza. This gesture is reflected in the curved architecture of the new lobby facade and the adjacent concentric tunnel which leads to offsite parking. These elements act to hold the edges of the plaza to the west and provide a contrast to the verticality of the building facade.

Outdoor congregation terraces are created within the plaza. The terraces are defined by a change in paving material, large shade trees, planting beds, and architectural seating elements—all of which reinforce the curving plan geometry. The change in paving material serves to provide a more tactile experience in the terrace as well as providing the opportunity for greater permeability. The large shade trees mitigate the harsh Texas sun. The architectural seating elements incorporate mounded berms of feature planting. Green roofs highlight the top of the new lobby to provide additional visual interest when viewed from above.
