2017 Oregon Residential Specialty Code adoption discussion

Richard Baumann, policy analyst, Policy and Technical Services, explained that

the 45-day period for accepting code amendment proposals was from August 1

through September 14, 2016. The 2018 ORSC is anticipated to become effective

October 1, 2017.

Mr. Baumann said that the division is looking for direction from the board to

select code change committee members and a chair, select a model code for the

committee to work from, and dates and process for code committee meetings.

Once the division receives direction from the board, the internal review of model

code begins.

Chair Lewis said that industry is currently using the 2014 ORSC and 2009 IRC

with Oregon Amendments as the base model code. Chair Lewis asked members to

make a recommendation on a base model code. She said that if the board follows

past practices, it would be to use the most current IRC. Her suggestion was for the

committee to use the 2015 IRC as a base with Oregon amendments.

Rebai Tamerhoulet said that the board and industry are familiar with the IRC. His

vote was to use the 2015 IRC as a base.

Vice-chair Bruce Dobbs and Tonya Halog also agreed that using the most current

code would be beneficial to the board and industry.

Motion by vice-chair Dobbs to use the 2015 IRC as a base model code and to

incorporate Oregon amendments.

Motion carried unanimously.

Chair Lewis said she has reached out to industry and stakeholders on behalf of the

board for an agreement on membership to the code committee and a committee

chair.

Chair Lewis asked for a motion from the board on the proposed vetted list for

membership to the 2017 Oregon Residential Specialty Code Committee:

Proposed code committee members:

State of Oregon Board memo

Building Codes Division January 11, 2017

To: Residential and Manufactured Structures Board

From: Richard Baumann, policy analyst, Policy and Technical Services

Subject: Temporary wood-sided structures and recreational vehicles

Over the last several months, the division’s Enforcement Section has reviewed the activities of

certain manufacturers of wood-sided, residential-type structures. Many of the structures were

constructed using a chassis and wheels for transportation. Some of the structures were temporary

in nature and some were used for dwelling or housing purposes. The division’s Enforcement

Section reviewed three regulatory areas:

1. Licensing requirements, specifically electrical and plumbing;

2. Code standards the products were built to; and

3. Inspection and permitting protocols that were followed.

The division has closed its initial investigation and now proposes a clear regulatory path for

recreational vehicles (RV’s). Enclosed is a temporary rule the division plans to enact (after

receiving feedback from the Residential and Manufactured Structures Board and the public). The

rule clarifies the definition of RV’s and eliminates the park trailer code in Oregon. This will

eliminate the division’s regulatory approval for a temporary wood-sided structure, such as a park

trailer. Those structures will be able to built and offered for sale in Oregon without state approval

which will align Oregon with 47 other states. This proposal will still recognize existing

requirements for temporary structures and structures designed to be used as dwellings under the

Oregon Residential Specialty Code.

By clarifying the definition of RV, this rule will relieve confusion created by industry regarding

temporary versus permanent wood-sided residential type dwellings. Our investigation found that

some manufacturers were building to an RV or seasonal use code standard while others weren’t

building to any standard. Structures for use or occupancy must meet minimum safety standards –

whether they are on wheels or not. Builders of wood-sided structures (with or without wheels),

will have the choice to seek local approval as a temporary structure or may choose to obtain state

approval for an R-3 type dwelling under the Oregon Residential Specialty Code. The state is no

Agenda

VII.A.

longer requiring approval of temporary wood-sided structures used or occupied by the public.

Again, manufacturers that choose to build temporary wood-sided structures – however identified

(“park trailer”, “tiny house”, etc.) – will need to seek approval directly from local government so

that planning, land use, fire and building code standards are effectively considered at the local

level. Those manufacturers seeking approval for permanent dwellings may choose to participate

in the state’s Pre-Fabricated Structures Program or work with local government.

These rules will remove the state’s preemption of local government over temporary wood-sided

structures (“park trailers”, “tiny houses”, etc.). Structures that are truly temporary in nature may

now be addressed by local government and manufacturers will no longer need state approval in

addition to local government approval.

The board will want to review proposed changes to the definition of RV’s on Page 3 of the

proposed rules. The other changes eliminate park trailer rules. Also enclosed is a copy of the

Temporary Structures and Uses code language adopted in the Oregon Residential Specialty

Code. The division is not proposing any changes to the existing residential code. We are only

providing the language for reference.

The division is requesting feedback from the board and the public before adopting these rules.

After receiving this feedback, the division will adopt a temporary rule and follow later with

permanent rule making. Because this matter is not the adoption of a dwelling code, the division

is seeking board input but does not need a formal vote of approval/disapproval. The division will

update the board once the temporary and permanent rule making is complete.

State of Oregon Board memo

Building Codes Division January 11, 2017

To: Residential and Manufactured Structures Board

From: Richard Baumann, policy analyst, Policy and Technical Services

Subject: Cost Analysis of Potential Energy Code Improvements - Earth Advantage

Action requested: Board review and discussion of the “Cost Analysis of Potential Energy Code Improvements”

provided by Earth Advantage.

Background: The Residential Specialty Code Committee (committee) is currently in the process of reviewing

a new base model code, existing Oregon amendments, and public proposals for the next edition

of the Oregon Residential Specialty Code (ORSC). The code review process began on August 1,

2016 when a 45-day notice was posted for the public to submit code amendments to the ORSC.

The comment period ended on September 14, 2016. The first committee meeting was in

November 2016, and they are scheduled to meet again in January 2017.

During the 45-day period to receive code proposals, there were five code change proposals

received that were energy-related as found in ORSC Chapter 11. The code committee also

received four additional documents supporting these energy related proposals.

In December 2016, the division received a copy of a document entitled “Cost Analysis of

Potential Energy Code Improvements” (dated December 2, 2016), prepared by Earth Advantage.

This document makes general energy-related code recommendations and cost analyses.

Discussion:

Because the board must make a finding regarding cost when it recommends approval of a

particular code or administrative rule, the board may choose to use the information contained

within this document to address cost issues for energy-related code proposals. Before taking

action on proposed code changes, the public is invited to provide information to the board in

person or in writing as part of the code review process. The division will then summarize any

public comments received for the board and its code review committee.

Cost Analysis of Potential Energy Code Improvements

December 2, 2016 Prepared by Earth Advantage

Cost Analysis of Potential Energy Code Improvements 1

Executive Summary Oregon is considering developing a pathway for zero energy construction: buildings that produce as much energy as they consume. Washington and California have already established zero energy code pathways; these pathways are increasing energy efficiency, reducing climate pollution , and saving home and building owners and renters money. Questions have been raised in Oregon about how to achieve a similar pathway and what the impacts are on capital costs and energy efficiency.

A zero energy code pathway involves decreasing energy use in new buildings and homes in Oregon by 65 percent in three-year incremental stages over the next 15 years. To achieve such a trajectory, building codes wou ld be updated regularly over the course of the 15-year period , achieving incremental reductions in energy use in new buildings and homes. The first two steps would be to improve building standards by about 10 percent, and then another 10 percent -presumed to occur over the course of 6 years. The methods and technology to achieve 20 percent savings are already well known in Oregon. Within Energy Trust territory about 40 percent of new homes were built above code in the past year and they averaged 20 percent savings above code. To examine these possible initial steps, this report assesses the incremental cost of constructing residential dwellings - both individual homes and multi-family buildings - to energy performance levels that exceed current Oregon code by 10 and the

combined 20 percent.

While it is evident that significantly increasing energy efficiency in new homes and buildings would save Oregonians millions of dollars over time, the first costs incurred by the bu ilder or developer to build a more efficient home or bu ilding are more uncertain. Th.is analysis considers the potential up front cost impact improved energy codes would have on builders and developers. The cost information contained in this analysis represents close to a worst-case scenario (highest potential capita l cost impacts) for a real-world builder. The project team took an exceptionally conservative approach in carrying out th is assessment. The determination of construction costs for this analysis does not include:

• Preferred sub-contractor pricing, bulk pricing , or effective negotiation by a builder's purchasing agent. Cost savings accruing to the builder or developer based on optimized design that reduces mechanical system sizing or labor installation costs. Energy efficiency incentive funding for producing a higher performing home or building .

Any expected incremental cost reductions between baseline and more energy efficient products that are likely to occur over time.

The analysis resulted in the fo llowing findings:

• Through energy modeling and cost estimating , the project team determined that incremental first year capital costs of more efficient construction practices ranged from a cost-neutral impact to a 4.1 percent increase when compared to current code, depending on the building type, location, and levels of energy performance.


When analyzed using a financial model, any initial increase in the cost of construction required to achieve the higher levels of energy performance are repaid by utility savings in less than 1 year to up to 7 years of occupancy, depending on building type, location, and energy performance level.

• When utility costs are considered alongside financed construction costs over the life of the building, the analysis shows that building with improved energy efficiency standards costs 1.5% to 6.5% less than bui ld ing under the current energy code.

Analysis Details The analysis considers prototypical single-family home and multifamily buildings in both Hillsboro and Bend, in order to consider climate and geographical variations. The analytical process included first conducting an energy model of the prototype buildings. Various building components and technologies were input into the energy model to create scenarios in which the home or building achieved the desired performance levels. Those components and technologies were then catalogued in order for the project team to conduct research into common pricing. To ensure a balanced and transparent approach, the analysis uses publicly available retail pricing information. Additionally, some cost information was supplemented by information from Northwest Energy Efficiency Alliance (NEEA) cost research. The cost information used in the analysis does not take into account such factors as bulk pricing savings or labor cost savings that are often achieved by builders familiar with high performance construction techniques and approaches. This cost analysis also does not factor in energy efficiency incentive programs that can reduce the overall cost of certain energy efficiency components. Therefore, the project team believes the cost information used for this analysis represents close to a worst-case scenario (e.g. the highest potential capital cost impacts) for a real-world builder.

Building Type Overview The report analyzes cost and savings for specific building designs for single family and multifamily projects. One design is used for all single family analysis and another is used for the multifamily work. The designs are actual examples recently built in Oregon. These prototype

structures are: • Single Family - In order to simulate typical single family housing activity, a 2,200 square

foot, 3-bedroom home design was selected that the researchers have seen constructed on a regular basis in the Portland suburbs in the past two years. This two-story home has common design features such as an attached garage and an open living plan on the main floor. The home was modeled in both Hillsboro and Bend in order to determine if different energy efficiency measures were required to attain the same level of savings.

• Multifamily - A 44 unit, 26,088 square foot multifamily project was modeled for this project. The unit was chosen for its rep resentative design. It is a low-rise building with wa lk-up entrances and no indoor common areas. The multifamily project was modeled in both Hillsboro and Bend, but the measures required to attain the varying levels of efficiency did not vary between the two locations.

• Heating Fuel Mix - When natural gas is available single family homes typically have gas heat. For this reason we modeled homes with gas heat, and gas water heating, at the 10 percent and 20 percent savings levels. In some parts of the state natural gas is unavailable and for that reason the research team also modeled the all-electric systems for homes at the 10 percent and 20 percent savings levels. New multifamily construction in Oregon typically uses electricity for heating and water heating. The utilization of gas water heating is a measure that is cost effective to employ when targeting mid-range savings. The 10 percent savings building was modeled with all electric systems and the 20 percent savings building was modeled with gas water heat and electric heat.

Cost Ana lysis of Potential Energy Code Improvements 4

Energy Consumption Analysis Approach: There are a variety of energy efficiency measures that could be employed to ach ieve greater than 10 percent savings in residential buildings in Oregon. We selected measures to include in this analysis based on what is commonly seen in homes that are seeking above code certification . The project team consults on a wider array of single and multifamily bui lding projects across Oregon. The team has experience with large volume builders and custom home builders. The measures selected for this analysis to attain the 10 percent and 20 percent savings levels are those that are widely adopted by the volume contractors in the construction industry.

• REMRate modeling - The energy savings was estimated using the industry standard energy modeling software REM/Rate v15.2. This software tool analyzes the building's shell , HVAC systems, water heating , and lighting fixtures . REM/Rate bases its estimate of annual fuel usage on the efficiency of the building systems and uses standard assumptions of plug loads, hot water usage, thermostat settings, plus local weather data. The team member that conducted the modeling is an industry expert who conducts over 1,000 energy models annually and followed local protocols that have been developed to ensure accuracy in estimating energy savings.

• Energy Efficiency and Solar - In addition to considering the energy savings that is available from efficiency measures, we also considered the use of Solar Photovoltaic Panels (PV) as an additional measure. Currently Oregon energy code allows PV to be utilized to achieve code requirements . Since achieving the 10 percent and 20 percent savings levels are regularly achieved by builders without the use of PV, this option was not used in modeling those homes.

Single Family Energy Savings Measures Fourteen different types of energy savings measures were analyzed for the purposes of this study. Within each measure type there were varying levels of efficiency modeled, for the team modeled savings for 4 different levels, 3 levels of attic insulation and two levels of wall insulation. The table below indicates what types of measures were included for single family homes to reach the different levels of energy savings.

Multifamily Energy Savings Measures The same types of measures that were analyzed for single family homes were also analyzed for the multifamily building in this study. The specific measures are sometimes different for the multifamily building, for instance Package Terminal Heat Pumps were modeled for the multifami ly building, but not the single family building. Because the multifamily building is a walkup building the team decided to model only unitary equipment. That means no central heating , ventilation, or water heating systems were analyzed even though those systems are typically very durable and may offer significant savings potential over unitary systems, especially if they are analyzed for lifecycle cost savings. Unitary systems are lower cost to install and the team decided the inclusion of those systems would represent the more conservative approach for this study.

Estimating Measure First Costs The baseline code buildings were estimated to cost $120 per square feet. This pricing was utilized for both sing le family and multifamily construction. Construction costs will vary depending on the quality of finish materials utilized and due to the availability of materials and labor. Costs can also differ significantly between multifamily and single family construction . The $120 per square foot cost was established as a level that is reasonable to consider for the size of buildings being considered and the types of finishes typical of housing for moderate income households. For example the window costs estimates are based on vinyl windows rather than on more expensive wood or fiberglass options. Additionally the home's two entry doors are assumed to be fiberg lass with Y.i lites with double pane insulated glass.

Construction costs were held constant between Hillsboro and Bend. There may be differences between the two markets , but since most material suppliers have distribution capacity in both markets and construction practices are largely the same, the research team decided that the one price was representative.

Cost information for the efficiency measures modeled at the 10 percent and 20 percent buildings was readily available because the technologies and methods are used regularly by builders in Oregon today. With in Energy Trust of Oregon territory about 40 percent of new homes participate in their new homes program and the average savings over code is 20 percent. That represents over 3,000 homes built in the past year at this level of performance. NEEA has compiled cost data for the typical measures utilized to achieve that level of performance. This study uses that cost information from N EEA in addition to current pricing for equipment that was researched on internet retail sites. This equipment pricing does not reflect any contractor discounts and the team views this as a conservative cost approach .

Estimating Lifecycle Costs A life cycle cost analysis was also conducted to offer a view of cost beyond merely first cost. Life cycle cost analysis is a decision-making tool that compares the owning and operating costs for energy using systems: heating , cooling , lighting , bui lding envelope, and domestic hot water. The analysis accounts for the in itial cost of constructing a building, as well as the cost of owning


and operating a facility over its useful life. These costs make up the total cost of ownership for a building. In addition to determining the first cost of constructing 10 percent and 20 percent above current code buildings, a lifecycle cost analysis was conducted using the Lifecycle Cost Ana lysis Tool, Version: 2016-A from the Office of Financial Management (OFM) in Washington state. This tool was based on a federal tool and was developed by OFM to plan state capital expenditures, but has also been adopted in Washington to analyze all energy code proposals and some affordable housing funding applications.

For this analysis, the replacement cost of measures was factored into the lifecycle cost analysis. Equipment, plumbing and light fixtures , solar panels were all estimated to have useful lives well short of 50 years. The length of a measu re's useful life was held constant across various efficiency levels. In that way the lifecycle costs were not influenced by subjective determinations of how long a measure will last, but each measure type was treated the same. The replacement cost intervals for measures can be seen in the Cumulative Expenditure Report that is a part of each LCCT report in the Appendices.

Analysis Results Table 3 below details the incremental increases in construction costs (first costs) required to achieve the above code levels of performance for the 2,200 square foot single family home. Incremental costs to achieve 10 percent savings in gas heated homes varied from 0.2 percent in Hillsboro to 0.5 percent in Bend. Although not shared in Table 3, the costs to achieve 10 percent savings for electric heat were estimated and totaled increased costs over code of 0.8 percent and 1.1 percent. The incremental costs for the 20 percent saving in gas heated homes were 1. 7 percent for both from Hillsboro and Bend. The costs for 20 percent savings with electric heat were 2.2 percent in Hillsboro and 2.3 percent in Bend.

Financial Analysis This analysis examines the finan cia l impact of the proposed savings at a first year level and with a fifty-year lifecycle cost approach. Both approaches are based on the consideration of capital costs interest paid back through long term financing and the lowered operating costs that come with increased efficiency. The sing le family financing assumes a standard 30-year mortgage with a 4 percent interest rate. The multifamily financing assumes a 20-year mortgage with a 4 percent interest rate.

Five different building types were modeled for each climate location. The lowest cost home for in Bend and Hillsboro from a lifecycle perspective was the 20 percent more efficient gas home.

Table 6. Total 50 Year Costs for 2,200 Sq Ft Home (Lifecycle Cost)

Code Baseline (Gas/Elec) $528,812/$530,420 $515,037/$513,97 4

10% Savings with Gas Heat $520,355 $507,463

20% Savings with Gas Heat $513,379 $503,753

20% Savings with Elec Heat $523 ,900 $509, 100

For all savings scenarios the fi rst year expenses are lower than the baseline code home. For instance the first year expenditures for the 20 percent savings home in Hi llsboro are $125 less than the baseline and in year 7 of occupancy the cumulative savings over baseline becomes positive and remains so for the rest of the building's estimated life.

Cost Ana lysis of Potential Energy Code Improvements 10

The numbers of years of occupancy required before the cumulative expenses of the savings scenarios overcome the initial capital expense varies between 1 and 7 years. For the 10% savings level these time periods are:

2 years for the cumulative expenses of a multifamily building to become less than those of a code building in either Oregon climate location.

• 2 years for the cumulative expenses of a gas heated single family home in Bend to become less than those of a code built home.

1 years for the cumulative expenses of a gas heated single family home in Hillsboro to become less than those of a code built home.

For the 20% savings level these time periods are:

4 years for the cumulative expenses of a multifamily building to become less than those of a code building in either Oregon climate location.

5 years for the cumulative expenses of a gas heated single family home in Bend to become less than those of a code built home.

7 years for the cumulative expenses of a gas heated single family home in Hillsboro to become less than those of a code built home.

Both the 10 percent and 20 percent better than code homes are better investments than the baseline code home, but the 20 percent savings homes are better long-term investments. This understanding provides a good motivation to move state building standards for single family homes towards higher levels of energy performance as quickly as is feasible for the build ing community to adopt the required methods.

The multifamily building built to 10 percent and 20 percent savings level show lower first costs and lifecycle costs than the baseline code building. The lower incremental costs associated with these levels of performance means that project owners will recover the initial incremental investment much fa ster. The 10 percent building fully recovers the additional capital costs in the second year of occupancy. The 20 percent building recovers the additional capital costs in the fourth year of occupancy. The net present savings for the 10 percent building are $410,887. The net present savings for the 10 percent building are $436,341 .

The lifecycle savings potential indicated for these higher energy performing buildings supports policies that promote buildings that are capable of supplying even higher level of savings than the 20 percent documented in this analysis. The savings provided by the 10 percent and 20 percent buildings comes with very little risk. Both building levels pay back the initial capital expense of energy efficiency measures within four years. This rapid repayment schedule should make policy makers secure in setting these leve ls of energy performance for multifamily construction projects as standard practice in the very near term.

Study Conclusions The first year and lifecycle cost savings represented by the 10 percent and 20 percent savings levels are significant and they should be adopted into code as quickly as possible. The initial costs of construction required to achieve these levels of performance are minimal - if not cost


neutral - and are quickly repaid by the utility savings. These levels of energy performance require between 1 to 7 years when using the most cost effective heating fuel for a given location and bui lding type. The 20 percent savings leve l is the average that Energy Trust of Oregon sees with participating new homes and it utilizes methods that are very common across Oregon. This building type fully recovers upfront costs with in four years of operation. That is a very secure provision of benefit to Oregon building owners and occupants.

Interestingly, the lifecycle savings potential for very high energy performing multifamily buildings could be sign ificantly greater than baseline current code options. While this analysis focused on the short-term cost impact of making 10 percent and 20 percent code improvements, market evidence of a few recent projects completed in Oregon suggest that multifamily construction that achieves very high energy performance improvement levels has an even lower overall cost in the first year of operation and over a 50-year lifecycle. One of these examples is Phase Two of Orchards at Orenco Station in Hillsboro, with Walsh Construction as the contractor and REACH CDC as the developer. This project was designed to deliver over 50% energy improvement and was completed for only a 5% incremental cost in 2016. The project team achieved the savings at this price as the resu lt of discipline to design and build with energy efficiency as a priority . Another high performance project completed in 2016 is the Iron Horse Lodge in Prinevi lle , built by Pacific Crest Affordable Housing, which delivered a 75% energy improvement through a mix of efficiency and solar. This project will achieve close to zero energy usage, meaning that over the course of a year it will consume almost the same amount of energy as is produced on site. The full cost recovery of all of the energy investments will occur in 10 years. At the same time, the greatly reduced operating expenses that accrue on day 1 of occupancy help the building owner keep rents lower and ensures that month utility costs can be affordable for these lowincome seniors on a fixed income.

Any first cost premiums for higher levels of energy performance should decrease over time as contractors become more familiar with the construction of efficient building assemblies, products become more widely available and heat pump technolog ies increase efficiency. As an example, the installed cost of solar PV has dropped more than 50% in the past 10 years and is likely to continue dropping in cost. Yet, even with first cost premiums, these project produce a lower overall cost in the first year of operation and over a 50-year lifecycle when compared to less efficient buildings, including current code buildings. Indeed, a multifamily building with 65% better energy performance than current code (equivalent to being "zero energy ready") is an estimated 11 .2% less expensive to build and operate over time than a code building.

While the practices needed to achieve 20 percent energy improvement are commonplace and easily integrated into standard building practices today, a greater number of contractors must become familiar with the advanced building practices required to achieve levels such as 65 percent before they can become standard practice (i.e. code). Nonetheless, the spread of those techniques and the achievement of that leve l of energy performance should be reasonably achieved over the next 15 years .
