This design challenge will create free-to-use, energy-efficient home plans that will result in lower energy bills and stronger structures to withstand extreme weather when compared to homes designed to minimum codes.

Design Team Challenge

This project will produce designs for single-family homes, accessory dwelling units and duplexes that exceed minimum energy efficiency codes and will include important resiliency features to better withstand Oklahoma's extreme weather.

The sets of construction plans will be available for free to the public.

Frequently Asked Questions

Q: I'm an architect and I want to respond to this. What do I need to do?

A: Visit "How to Do Business with OKC" web page and follow instructions to register as a vendor. The challenge requires design teams, including licensed architects, mechanical and electrical engineers, home energy modelers, construction specialists and designers to create a comprehensive approach to creating prototypical plans that can later be site-adapted for construction.

 

Q: What Energy Efficiency standards will be required?

A: The home plans must meet or exceed 2021 IECC and ASHRAE 90.1-2019, minimum energy standards the U.S. Department of Housing and Urban Development adopted in April 2024. Additional details will be published in the Request for Qualifications documents.

 

Q: How will we know the home designs are more energy efficient than the City's current requirements?

A: A third-party energy modeler will evaluate the energy models that provide a 30-year utility bill savings estimate and compare those to the baseline home using energy models such as the Home Energy Rating System (HERS) score or Energy Rating Index (ERI) and compared against OKC's minimum design code standards.

 

Q: What is the purpose of this project?

A: Ultimately, the goal is to provide consumers a resource that shields them from rising utility costs, an increasingly hotter climate and avoid the havoc extreme weather can wreak on one's home.
