Describe the end use of the building:
The Chapman In-Build is a primary residence for Dr. David Chapman and his wife Julie. They also rent the apartment above the garage, short term, to people visiting Edmond through AirBnB.

How did SIP construction help you get this job?
The property is located approximately 500' from a train track, so they were looking for an insulating system that would also act as a noise damper. Mr. Chapman is also very interested in sustainable city planning and building homes that are environmentally friendly. He liked the fact that there would be less waste building with the SIPs and that his home would be more energy efficient.

SIP wall thickness and core material: 6" and 8" EPS foam walls
SIP roof thickness and core material: 8" EPS foam roof

Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
The physical design of this structure lends itself well to SIP construction. The roof/3rd story deck worked perfectly with SIPs because of the superior strength of the panels.

Describe any innovative design elements or structural engineering involved:
The home's tall narrow design and red brick exterior helps the modern appearance of the home to blend in well with Edmond's historic downtown.

Describe the HVAC system used on the project:
The home is heated and cooled with a 4-ton electric conventional forced air furnace/air conditioner. A fresh air return was also installed. Ceiling fans were installed in every room.

Any additional comments on the project:
The walkways were made with locally harvested crushed granite that allows rain water to drain naturally into the ground rather than running off through city drainage system. Rain containers have been purchased and will be installed to capture and reuse rain water. The home was featured in an article published in September 2017 in the Edmond Outlook. The article titled "Urban Aspiration" is about downtown revitalization and urban sustainability. Dr. Chapman has been lecturing and studying New Urban-ism for several years and said it was "time to close the gap between his walk and talk" and move from their suburban home into the urban area.
