State Energy Code. The State Energy Code is part of the State Building Code, which sets the minimum construction requirements for buildings in the state. The State Energy Code provides a maximum and minimum level of energy efficiency for residential buildings and the minimum level of energy efficiency for nonresidential buildings.
The State Building Code Council (SBCC) maintains the State Energy Code. SBCC reviews, updates, and adopts model state building codes every three years. The State Energy Code must be designed to:
SBCC must adopt state energy codes that require buildings constructed from 2013 through 2031 to move incrementally toward a 70 percent reduction in energy use by 2031. The State Energy Code must consider regional climatic conditions. SBCC may amend the State Energy Code by rule if the amendments increase energy efficiency in the affected buildings.
Reach Code. A reach code is an energy code that goes beyond the state minimum requirements for energy use.
Washington State Energy Code for Residential Buildings. Each city, town, and county is required to enforce the Washington State energy code for residential buildings or adopt the statewide residential reach code. Any other local residential energy code is preempted.
The allowance for space heating equipment efficiency to offset or substitute for building envelope thermal performance is removed.
Statewide Residential Reach Code. SBCC must adopt by rule a statewide residential reach code for optional adoption and enforcement by any city, town, or county as an appendix to the 2021 residential energy code and must be effective by July 1, 2024. The statewide residential reach code must achieve the 70 percent reduction in energy consumption and greenhouse gas emissions required in the 2030 energy code for residential buildings in incremental steps by the 2027 energy code. The reach code may not require more annual renewable production than a residential building is predicted to use. The Department of Commerce must develop a proposal covering the technical provisions of the reach code and rule-making documents.
Eliminates the net-zero readiness requirement for all new buildings by December 1, 2034, including the requirement for all new buildings to be wired for photovoltaic panel installation.
Eliminates the requirement for all new buildings to have a reduction of at least 80 percent in annual net energy consumption using the 2006 State energy code as a baseline.
Removes the home affordability cost analysis required to be conducted for any change to the Washington State energy code for residential buildings.
The committee recommended a different version of the bill than what was heard. PRO: This bill is needed to meet the state's statutory requirements to lower greenhouse gas emissions. Increasing the energy efficiency of new buildings will decrease utility bills for building owners and tenants. The costs of increasing energy efficiency in new buildings is a fraction of the lifetime costs of a building and it is cheaper to upgrade efficiency while the building is built, rather than as a retrofit. The reach code that would be developed under this bill would provide options and flexibility for local governments.
CON: The requirement for net-zero ready buildings and homes increases the cost of construction and will drive up the cost of housing. There are existing supply chain issues and the increase in demand for products that are not widely used will make it harder to source those goods. The current workforce is also not equipped to handle an increased demand for specialized positions.
The bill does not provide a definition of net-zero or net-zero readiness and the requirements to meet net-zero readiness are not clear. The current building and energy codes are difficult to meet and the requirements in this bill will make it harder.
The decisions about specific energy sources for a building should be left to the owner, including the decision to install solar panels or the use of alternative heating sources.
The Legislature should prioritize the use of data on these topics and study the effect this bill would have on housing prices before implementing the changes in this bill.
OTHER: Current building codes already have high efficiency standards for buildings. This bill would create multiple codes and redundancies with the current code. School districts should be exempt from the requirements under this bill.
