3rd Draft - December 23, 2009

Residential Program - NEW CONSTRUCTION:

All new construction projects, excluding LEED (with # energy and # water points (state how many points or what level of certification), are required to comply with the following sections. The exemptions listed above must show their intent to meet the requirements at the building permit review stage and receive final certification under the applicable program, prior to receiving a certificate of occupancy.  (Need to determine if any additional programs would be suitable for an exemption.)

Meeting Minutes:  BuildSmart Technical Advisory Committee

December 16, 2009   5:30 pm - 6:30 pm

Old Business

Review meeting minutes. In reality, we are looking at simple payback not ROI. ROI compares investment between two or more possibilities. MOTION: Rick Stark moves to adopt minutes from December 2nd and December 9th meeting with amended changes. Brain Bennet seconds. Meetings moved to first and third Wednesday of every month and expand meeting time to 1 ½ hrs.

New Business

1. Review Rick Stark's Proposal for Additions and HERS requirements.

Comments:

Simple and easy to understand Meets the 30% goal. Seems fair and equitable Need to have a bottom HERS threshold for existing structure. Don't want to punish the guy who built a 60 HERS home two years ago and now wants to add on an additional garage and needs to get his existing sq ft a 30% improvement. 70 may be an appropriate threshold considering that is where is 30% improvement above IECC. What about the guy who is building a garage on? Would he need to improve the existing house? If the goal is to improve existing structures an "exception" does not seems appropriate.

Rick will take comments and bring another proposal forward.

2. Tom  Harned HERS Q&A session:

Energy Audit's;

Energy Audits do not require use of a program, but HERS does. No national standard; varies types of energy audits. Some audits are walk through only while other audits conduct blow door, duct blaster, thermal photography to identify specific problems of the structure. Specific to the needs or concerns of each specific home i.e. cold rooms or drafts Identifies health concerns associated with tightening the BE. Looks at simple payback, does equations by hand Looks at safety and backdrafting

HERS

Utilizes a software program to project performance for new construction and existing construction. Also involves a performance tests to ensure performance projections occur. HERS raters are certified by a national organization. Quality assurance. Code of ethics. Requires three months of coursework and field practicals. Looks at the overall performance of the structure, does not look at one aspect of the structure such a BE tightness or mechanical efficiency. Looks at simple payback, does equations via the software program. Also applies the simple payback as a function of overall performance, while audit assess payback per specific improvement. HERS takes into consideration the local climate and number of heating days in your local Provides a comparison between homes while an audit just looks at how to improve the energy efficiency of the existing home. RESNET looks at energy only while Building Performance Institute looks at health and safety. Provides a projection HERS score based on plans and a confirmed HERS score based on a blower door and duct blaster test.

Does HERS take into consideration snow load building?

Yes,  it can take into consideration extra mass and bridging. HERS gives an R value for everything in a wall. Looks R-value wall by wall, that is why a larger house with many corners can take longer and cost more than smaller simpler designed homes.

Does air conditioning affect HERS score?

Yes, if you don't have air conditioning then your home performs better, consequently giving you a better HERS score if you did have air conditioning.

Does the type of radiant heating get brought into calculations?

No, HERS looks at the source of heat for floor, not the implementation or design.

HERS has a simplified and detailed program.

The simplified has less detail on the mechanical and solar aspects.

HERS provides various types of reports for the homeowner or contractor to make informed decisions, not just a HERS number.  Creation of some reports take additional time by the HERS rating and consequently may cost additional beyond the actual HERS rating.

Examples of reports are as follows:

"Performance Summary", "Emissions Report", Component Loads, Component Design, Air Leakage Report, Economic Summary, Performance Summary

HERS will identify rebates available for various improvements. The rater will have to be aware of these to apply them.

Mechanical equipment and BE are large focuses in the HERS program.

Comments:

Having a County building inspector familiar with HERS and building science will provide additional guidance to builder and help ensure HERS score and suggested energy improvements are fair and consistent.

Can HERs rater be familiar with project to provide suggestions to improve the HERS score by just looking at the plans?

Brian Bennet, YES.

Once the contractors and architects get familiar with HERS they will see "points" when they remodel or create new construction. Improvements are not hidden.

Next Meeting January 6, 2010

Summary and Comparison of Various Options for Additions and HERS:

RS Option:

Requires a HERS for the entire structure, new and existing sq ft, based on the following Existing structure; 30% improvement to current HERS rating. Addition; new sq ft meets new construction HERS requirements based on the amount of sq ft being added. Additions that involve a 50% sq ft increase will be required to meet the new construction HERS sliding scale for the entire home. Two HERS scores are required, one is pre-permit for the existing structure, the second a post-construction performance HERS rating.

Example A: 4000 sq ft home with a pre-addition HERS rating of 200. 800 sq ft addition requires a 70 HERS (per new construction sliding scale). The post-addition home will be required to meet a 128.3 HERS rating for the entire structure.

((4000)(HERS 140)) + (((800)(HERS(70)) = 4800 X

616,000/4800 = 128 HERS for the entire structure

AR Option: Two possible paths to compliance.

Path I

Additions; the new sq ft would be required to meet a HERS rating based on the entire sq ft, per the new construction sliding scale. Existing Structure: no improvement to existing structure.

Example A: 4000 sq ft home applies for a 800 sq ft addition. Per the new construction sliding HERS scale a 4800 sq ft home is required to meet a 58.5 HERS. The sq ft for the new addition will be required to meet a 58.5 HERS rating. No improvements will be required for the existing home.

Path II

Requires a HERS for the entire structure, new and existing sq ft, based on the following formula and the new construction sliding HERS sliding scale; ((HERS Rating for the new sq ft) X (.20)) + ((HERS rating for the existing sq ft) X (.80)) = HERS rating for the entire structure One HERS rating will be required post-construction.

Example A - 4000 sq ft home applies for an 800 sq ft addition;

((80 X 62.5 HERS) + (70 HERS X .20)) = 64 HERS for the entire structure.

Boulder Option: Uses a separate sliding scale based on existing size of the structure and % of structure which is being renovated or % of increase to the existing footprint. Boulder County is currently in the process of replacing this process.

Example A - 4000 sq ft home applies for a 800 sq ft addition. Entire structure must meet an 80 HERS
