The Integrative process supports high-performance, cost-effective project outcomes through an early analysis of the interrelationships among systems.


Before design begins, an integrated design team must conduct a comprehensive site assessment of existing physical, biological, and cultural conditions that will inform planning and design.


Projects that are designed to conserve water, maximize the use of precipitation, and protect water quality encourage strategies and technologies that restore and mimic natural systems.


Proper soil management as a design element and construction priority can serve as the foundation for robust vegetation, filtering pollutants and help prevent excess runoff, erosion, sedimentation, and flooding.


Sustainable construction encourages projects to protect air quality through low-emitting equipment, strive for a net-zero waste site, ensure healthy vegetation through soil restoration strategies, and protect receiving waters from polluted runoff and sedimentation


O+M promotes maintenance strategies that maximize the site’s long-term potential in providing ecosystem services. Strategies include reducing material disposal, ensuring long-term health of soil and vegetation, reducing pollution, conserving energy, and encouraging the use of renewable energy.


The demolition, selection, procurement, and use of materials in site design and construction present considerable opportunities to decrease the amount of materials sent to landfills, to preserve natural resources, to reduce greenhouse gas emissions, and to support the use of sustainable building products.


Sustainable construction encourages projects to protect air quality through low-emitting equipment, strive for a net-zero waste site, ensure healthy vegetation through soil restoration strategies, and protect receiving waters from polluted runoff and sedimentation


Outdoor opportunities for physical activity, restorative and aesthetic experiences, and social interaction are promoted. Projects are encouraged to address social equity in their design and development choices.

austin central library

project overview

Supporting Sustainable Water Use

Integrating Interactive Waterscapes

Accommodating All Generations and Dogs

Address: Austin, TX
LEED Certification:

Certified Date: July 2018

The New Central Library is replacing the John Henry Faulk Central Library as the new community oriented social hub of downtown Austin. The design focused on creating maximum daylighting illumination and included a large rainwater collection system. The building is the nation’s first LEED Platinum Certified library and is a prime example of sustainable design.

The site of the New Central Library is a redeveloped brownfield. This involved excavating and properly disposing of approximately 30,000 cubic yards of contaminated soil and construction debris from the site prior to construction of the new library. The urban site incorporates vegetative cover for approximately 33% of all open space and pre-development imperviousness has been reduced by 36%.

The rainwater collection system eliminates the need for potable water in irrigation and bathrooms. The system is 85% efficient and is expected to supply close to 813,500 gallons of water per year. On site captured grey water is used to meet irrigation demands and a condensate collection system is used to meet demand for indoor potable water if sufficient rainwater is not collected. These design strategies predict a 40% reduction in the use of indoor potable water and an 80% reduction in irrigation potable water use.

The project also uses alternative energy sources to reduce greenhouse gas emissions. On site solar panels account for 8%, natural gas accounts for 9%, and Austin Energy’s GreenChoice program that sources wind power, supplies the remainder of the facility’s electricity needs. Other strategies used to decrease energy consumption include, demand-controlled ventilation, under-floor air delivery, daylight harvesting and use of district supplied chilled water for AC systems. Energy efficient construction practices such as reduced demolition cost, diverted waste and recycling help reduce greenhouse gas emissions. The construction process diverted approximately 93% of on-site generated waste away from landfills. The project also aims to improve the indoor experience by using materials that emit lower levels of VOC’s and installing a CO2 monitoring system that provides feedback on ventilation performance. Additionally, the building ensures that 99% of regularly occupied spaces have access to views and 81% are illuminated by daylighting. With regards to transportation, the New Central Library has 160 bike storage spaces and 8 alternative fuel charging spaces available for the building users. There are also 3 Capital Metro lines within ¼ mile of the building. The library also connects to hike and bike trails on Shoal Creek and the nearby Lady Bird Lake.




Water Treatment Plant 4 Administration Building

project overview

design features

environmental features

Address: Austin, TX
LEED Certification: Gold

Certified Date: July 2018

Water Treatment Plant 4 (WTP4) is Austin’s newest water treatment facility. The plant can treat more than 50 million gallons of water per day. With WTP4, Austin Water hopes to address rising problems of demand and reliability - a result of the growing population of Austin and the aging of water infrastructure. The LEED Gold Certified Administration building, which contains offices, conference rooms, and the control room, serves as the headquarters for the entire plant.

The site design preserves 70% of the total site area by restoring its natural habitat through native planting. It also implements a stormwater management plan that protects stormwater channels from erosion. The building design claims to reduce energy cost by 48% and energy consumption by 46%. Strategies such as high efficiency glazing, reduced lighting power and water source heat pumps allow the building to be energy efficient. Additionally, the project uses wind energy, through Texas GreenChoice to power 100% of the facility’s electricity needs.

The administration building boasts an innovative and energy efficient design that embraces an industrial aesthetic; the design responds not only to the function of keeping Austin’s water supply clean but also to the goal of keeping Austin’s environment clean.

Austin Animal Center Kennel Addition

Address: Austin, TX
LEED Certification:

Certified Date: August 2006

The new kennel and visitor rooms aim to improve indoor experience by implementing HVAC zoning and responding to feedback from a thermal comfort survey. Mechanical systems which can be easily controlled and adjusted have been installed to create comfortable thermal and lighting conditions for both animal and human occupants.
Additionally, the kennel addition includes a breezeway that has enabled outdoor air ventilation to all occupied spaces to exceed the minimum required ASHRAE standard by 30%. Overall, the new addition hopes to improve the animals’ quality of life and create spaces that help visitors form loving relationships with the animals.
