What is ‘Emerald’ Certification?
The Planet Clark Emerald House (PCEH) is designed and engineered to be built to the highest sustainable building standards within the parameters of the available budget, land, and resources.
Emerald Certification is the most stringent certification and highest achievement in sustainable building by the National Association of Home Builders under their National Green Building Standard.
PCEH is the first NGBS-Emerald certified house to be built in Clark County. This is a leading example of how communities should build in order for their citizens to thrive now and in the future.
Certification standards within the NGBS are used to gauge building performance and environmental impacts.
A few of the better building practices include:
1. A building envelope with reduced air infiltration for more energy efficiency.
2. Low-flow plumbing fixtures for water conservation.
3. Selection of non-toxic building materials, paints and finishes for healthier indoor air quality, and more.
Target certifications for this project include:
- National Green Building Standard™ (ICC 700-2008) – Emerald level
- Earth Advantage™ New Homes – Platinum level
- Northwest ENERGY STAR® Homes
- EPA WaterSense
- EPA Indoor airPLUS
- Home Innovation – NGBS Green Partner
Where newer technologies in the past required compromise in design and/or functionality, that is no longer the case. Combined with innovative design, building to these certification requirements will result in a beautiful home that operates with reduced energy consumption, improved indoor air quality, and lower impact on the land and environment.
“Sustainable development is development that meets the needs of the present without compromising the ability of further generations to meet their own needs.”

Learn about the inspiration and progressive home building project that turned an unused tax lot into a home for a family in need. This Clark County Project has won numerous awards and is the first NAHB Emerald Certified Home in Clark County, Washington. Here are a few videos that demonstrate the planning and construction process for the Emerald House. Clark County Building Safety and the teams in Community Development, along with Planet Clark Building Partners and Volunteers worked tirelessly to complete this Emerald Certified Green Home. The benefits of this green home are enormous, and with positive and lasting impact our economy, environment, community, and society as a whole.
Here are seven sample worksheets from the NGBS Emerald Certification Workbook which is based on an excel spreadsheet. These examples don't have actual scoring data for this project, but they demonstrate the point system and how points are acquired to achieve certification. While you may not be able to achieve the maximum points within one specific category, the points are cumulative and you must be able to achieve the minimal scoring requirements to achieve Emerald Certification.
