Leading the Way with Achieving Net Zero

As industry leaders in sustainable engineering design, we are committed to delivering high performance solutions that align with the latest DC energy code requirements. Washington, D.C. is one of the first major cities in the U.S. to adopt a code focused on achieving net-zero energy. This step aligns with the city’s ambitious sustainability goals, including reducing greenhouse gas emissions and improving building performance.

Overview of Appendix Z:

The 2017 DC Energy Conservation Code (DCECC) governs energy efficiency requirements for new and existing buildings in Washington, D.C. Appendix Z of this code is a significant addition that outlines requirements for net-zero energy buildings in D.C. Appendix Z is designed to push buildings toward achieving net-zero energy (NZE) performance, meaning they produce as much energy as they consume on an annual basis. It applies to both new constructions and major renovations and supports the District’s goal of becoming carbon-neutral by 2050. The Salas O’Brien team has 15 local net-zero projects in design, construction or completed.

A company of firsts:

Our approach integrates cutting-edge energy-efficient technologies, innovative design strategies, and a deep understanding of regulatory standards to create buildings that perform at the highest level. By leveraging our expertise in net zero strategies, we help facilities significantly reduce energy consumption, decrease operational costs, and contribute to a healthier environment for students and faculty. This has lead to a number of firsts including:

• First LEED Platinum School for DCPS
• First Historic NZE School for DCPS
• First Project in DC designed to Appendix Z DC Energy Code
• First Project in country to achieve LEED pilot credit IEQc65p1 (IAQP) with electronic
  MERV filtrations.

Our experience with net zero and the DC energy code positions us as your trusted partner for sustainable building solutions. With a strong track record of success, we are dedicated to helping schools and institutions navigate the complexities of energy efficiency upgrades.
