Workplace Buildings and Office Interiors

As we spend more than 90% of our days indoors, much of which occurs in our workplaces, we realize the human health, well-being, and productivity benefits of interior environments that are both high-quality and resource-efficient. Since its inception, SDC has provided green building consulting for millions of square feet of office space. This includes base buildings that will be leased out to tenants (LEED-CS), interiors work within an existing building (LEED-CI), and whole-building new construction or major renovations (LEED-NC), as well as continuing operations (LEED-O+M) and operational energy performance (ENERGY STAR).

1875 Pennsylvania Ave, Washington, DC: This Class-A commercial office building features 13 floors of offices, workstations, and conference rooms, along with three levels of parking. SDC provided LEED for Operations and Maintenance (O+M) and ENERGY STAR certification services. The building’s energy, water, and waste efficiencies were optimized, resulting in ENERGY STAR verification in 2020 and LEED-O+M Gold-level certification in 2021.
