USGBC Awards LEED Gold Certification to 2020 K Street

LaSalle Investment Management and Transwestern today announced 2020 K Street, NW received LEED Gold certification by the U.S. Green Building Council (USGBC) under the Leadership in Energy and Environmental Design (LEED) for Existing Buildings: Operations & Maintenance™ rating system.

Transwestern's on-site property management team worked with the building ownership, LaSalle Investment Management, to implement a number of operations and maintenance procedural changes, including: optimizing the performance of all building mechanical systems; retrofitting all lighting systems with energy efficient fixtures and bulbs; installing a Global Lighting Control System; installing variable frequency drives on all relief fans, cooling tower fans and condenser water pumps; installing an energy-efficient cooling tower filtration system; retrofitting the indoor plumbing fixtures to reduce indoor water consumption; installing high-efficiency air filters on all HVAC equipment to reduce the level of airborne particulates throughout the building; and performing a waste stream audit to identify opportunities to reduce waste and increase recycling – currently the building recycles more than 80 percent of all waste.

As a result of these efforts, the buildings quarterly savings are:

  • 427,888 kWh of electricity, enough to power 36 homes for a full year
  • 9,335 gallons of oil, enough energy to heat and cool 46 homes for a full year
  • 2,216 gallons of gasoline, enough to drive 62,052 miles
  • 1,477 mature trees, enough to produce 18,305,482 sheets of newspaper
  • 651,769 gallons of water, enough to meet the fresh water needs of 11,587 people for a quarter
  • 759 cubic yards of landfill airspace, enough to meet the needs of a community of 3,900 people

"We are thrilled to have received LEED Gold certification at 2020 K," said Natalia Evstigneeva, senior property manager. "Due to the joint efforts of the building occupants and the management team, we have achieved more efficient and sustainable building operations that ultimately translate into reduced operating expenses."
