Research Forest Lakeside, Building 4 and Building 5

Gold – LEED Core and Shell


Both of these office buildings in The Woodlands, Texas were designed to enhance a connection to nature and offer views of Lake Woodlands. Significant efforts were made to prevent erosion to the lake and reduce water use. The two buildings capture facility condensate and stormwater for reuse in irrigation. An oversized storm system stores the water for reuse and allows particulates to settle out. Both buildings’ long facades are oriented south so the highest solar heat gain reaches only the short east and west ends of each building. Each façade utilizes different transparent and reflective low-e, high-performance and insulated glass depending on its orientation. GreeNexus is providing consulting and Enhanced Commissioning assistance, with the facilities targeting energy reduction, water reduction and access to local amenities.

  • Building 4 – 300,000-square-foot, 12-story office building for multiple future tenants.
  • Building 5 – 200,000-square-foot, eight-story office building for a single tenant.
