Office plaza earns LEED platinum recertification

For the second time, the home of real estate investment firm Watt Cos. has earned the highest possible LEED certification, attaining platinum status from the U.S. Green Building Council.

Watt Plaza exceeded its previous platinum performance by five points, thanks to ongoing improvements and sustainability commitments from all vendors servicing the building, according to a press release.

Watt Plaza was the first building in Century City, Calif., to achieve LEED platinum certification, and the platinum certification for Existing Buildings Operations and Maintenance is the facility’s third LEED certification.

The U.S. Green Building Council LEED certification system is the nations benchmark for the design, construction and operation of the worlds greenest, most energy-efficient and high-performing buildings. 

The certification “is especially noteworthy because our building has been operational for over 30 years,” said Nadine Watt, president of Watt Cos. “Sustainability is a top priority for us.”

Watt Plaza embraced groundbreaking initiatives to reduce its environmental footprint. Realizing a reduction of more than 31 percent in conventional transportation trips through an Alternative Commuting Transportation program, Watt Plaza is notably the first commercial office building in Century City to install electric vehicle charging stations in the parking facility to encourage the use of emission-free vehicles. The installation of a white roof to reduce the heat island effect was also part of its sustainable site development measures. 

Watt Plaza achieved a 66 percent reduction in annual landscape water use compared to the already-low regional average. The achievement was due in part to a landscape palette that centered around drought-tolerant plants and use of recycled ground covers and a web-based irrigation system that prevented overwatering and ensured the health of the plants.

As part of the engineering teams ongoing commitment to building improvement, the building underwent a complete third party retro-commissioning of all its equipment and systems in 2016. This comprehensive process spanned multiple months and allowed the engineering team to evaluate energy usage by system, develop cost savings calculations on potential projects and test the performance of all building equipment. This process included upgrades to LED fixtures, improvements to buildings automation system operating parameters and general renovations to improve both occupant comfort and energy conservation. 

Occupancy sensors were also installed throughout offices, common areas corridors, stairwells and restrooms, realizing a drop in electrical consumption by 690,000 kWh and improving the environment with an annual reduction of 936,655 pounds of carbon dioxide, 6,849 pounds of sulfur dioxide and 3,624 pounds of nitrogen dioxide.
