Alex ReNew: Building of the Year 2018!

The Alexandria, Virginia water authority, otherwise known as AlexReNew, wanted a new headquarters building that was not just super sustainable (LEED Platinum), but also designed to better involve the community and reflect their attitude towards sustainable water management.

Located at 1800 Limerick Street in Alexandria, the HQ sits on the same grounds as the water treatment facilities. With two 40’ long by 10’ deep fresh water aquariums on one wall in the lobby, and a museum on the other, a living wall utilizing reclaimed water supplied from their facility seemed a natural fit for the final wall. But Alex ReNew wanted to go even one step further and ensure the wall was reaching its maximum benefit.

25’ tall and 9’ wide, the wall dominates the South end of the lobby in the Alex ReNew headquarters and gave us a gigantic area to turn into an air filter to work with. If you look closely at the top of the wall – actually, you don’t have too look too closely since’ it is a 3’ wide HVAC vent we are looking at here – you will see what GWS and AlexReNew did that was so special.

Given its location, there was no way to have an HVAC chamber behind the wall, so instead – we put a pipe in the middle of the wall and draw the air from the lobby in through the wall with this HVAC pipe- and then use this green wall freshened air to supply the offices on the 2nd floor of the building with supplemental fresh air.

Based on all of these items, In 2018, the US Green Building Councils National Capital Region named the Alex ReNew building the Sustainable Building of the Year in the National Capital Region.
