Remodels, additions and converting unconditioned space into dwelling space can be challenging. Energy professionals have a unique skill set that is an excellent fit to address this need and ensure it is done within the bounds of code. This presentation will answer questions and set them up for success. Workshop focus: Chapter 5, 2018 WSEC-R Code: Existing Buildings
The WSU Energy Program's C3 calculator is a resource for remodels and additions to meet code using area weighted u-values allowing the designer and builder the freedom of material and system selection. An update should be ready to present at this conference. Oakridge National Labs Building Science Advisor tool: https://bsa-new.ornl.gov
When upgrading these spaces, private citizens make the investment on small, energy efficient dwellings. They free up units in government subsidized affordable housing while increasing tax revenue. Our goal is to make the code requirements for these upgrades less confusing. In addition, these types of improvements could potentially trigger upgrades in the main living space for HVAC, DHW, weatherization and potentially decarbonization opportunities.
Code Definitions: Additions, Alternation, Repairs, and Change of Use. Implications of Code: Accessory Dwelling Units, Metal Buildings (mostly in rural areas), Attic and Basement Retrofits.
Learning Objectives:
By attending this session, attendees will:
Understand the basics of converting a garage, metal building, basement or attic into a separate dwelling space according to current Washington State Energy Code
Understand the difference between an addition, alteration, repair and change of occupancy under the Washington State Energy Code
Understand how to access two different open source online tools that will assist with decision making and code compliance when working with remodels and additions
