Santa Monica adopts Zero Net Energy Code for all new single family construction

Monday, June 19th, 2017

.

.

On May 1, 2017 Santa Monica became the first city to adopt zero-net energy (ZNE) requirements.  The State of California is planning to implement such a code state-wide but this will not be implemented until the 2020 T-24 code cycle so Santa Monica is out in front with net-zero.

.

The basic premise of ZNE requires projects to generate enough of their own energy from renewable energy sources (solar PV for example), to equal what they use from the utility grid over the course of a year.  For now this requirement only applies to new residential projects, not additions or alterations.

.

However the ZNE requirement is parallel to the city’s Energy Reach Code which requires all new low-rise residential projects to be designed to use 15% less energy than the allowable energy budget established by the 2016 California Energy Code (Title-24).  This presents some challenges as projects that may comply with the reach code (15% better than T-24) may not comply as a ZNE project.  Conversely projects that can demonstrate ZNE compliance may still fall short of the 15% better than T-24 energy use.  One does not always equal the other.

.

This new code update became effective May 1, 2017.  This emphasizes the importance of getting your Title-24 Energy Consultant involved in your project early in the design process as most projects will struggle to comply and will involve a lot of back and forth as different design and energy saving strategies are modeled, tested and revised to get the project over the finish line cost-effectively.

New ASHRAE 62.2 Residential Ventilation Code Guidebook Available

Wednesday, August 10th, 2011

.

Starting January 1, 2010 California began enforcing the ASHRAE 62.2 Indoor Ventilation Code as part of the new Title-24 Building Efficiency Standards.  Many architects, contractors, and building departments have been struggling to understand and implement the requirements as they wade thru the fairly complex and dense language of the ASHRAE 62.2-2007 code book and the references contained in the 2008 Title-24 Building Efficiency Standards and the Residential Manual.

.

The California Energy Commission has promised and delivered a very helpful users guide that is now available for download.  Entitled: “Guide to the Indoor Ventilation Requirements of the 2008 Building Energy Efficiency Standards (ASHRAE 62.2).

.

The guide contains, in a checklist format, the requirements for showing compliance with an exhaust-only ventilation approach including a very helpful appendix that contains the much anticipated sample note blocks that can be placed on the building plans for plancheck without the need to complete the actual CF-6R-MECH-05 Certificate of Installation which is not required to be produced until inspection.  This allows the designer to specify on the plans submitted to plancheck the requirements for ventilation airflow, the rooms where the whole-building and local ventilation exhaust fans will be located, and the duct sizing for the whole-building and local ventilation.

.

These sample noteblocks can now be used and place on the plans to meet the requirements for submittal of the ventilation system specifications for plancheck.

California PUC Lifts hold on C.S.I. Solar Incentives

Wednesday, August 4th, 2010

The California Public Utilities Commission issued a new Assigned Commissioner Ruling (ACR) on July 29, 2010 lifting a temporary hold on the issuance of confirmed reservations for Performance Based Incentive (PBI) and government/non-profit projects established by a July 9th ACR.

.

The July 29th Ruling directs the CSI Program Administrators to resume processing and issuing confirmed reservations for all applications, including those impacted by the temporary postponement and held in queue in the order received, subject to the existing rules and processes of the program.

.

The Commission will continue to consider the three modifications proposed in the July 9th Ruling (see below), which are 1) removal of the 8% discount rate embedded in the calculation of performance based incentive (PBI) payments; 2) reduction in the incentive rate offered for government and non-profit applicants; and 3) shifting of $20 million from the program administration budget to the incentive budget.

.

If the Commission adopts either of the proposed incentive modifications, it is intended that such changes would apply only on a going forward basis, applicable to new applications seeking incentives after the date of any such decision.

Santa Monica Quality Installation Training May 6, 2010

Monday, April 5th, 2010

.

The City of Santa Monica is hosting a free training session on how to properly install insulation.

.

Mark Madison, certified HERS rater, will show you how to install insulation correctly in order to comply with the Title-24 HERS QII (Quality Insulation Installation)

.

Santa Monica is considering a requirement that all low-rise residential projects have a HERS verified QII inspection.

.

If you are an insulation contractor this is a great opportunity to bring your entire crew to an actual construction site and get hands on training on how to comply with the strict QII requirements.

.

If you are an architect or general contractor this will provide a useful education on what to look for and expect from your insulation contractor on your next project.

New Title-24 Refrigerant Charge Verification test procedures

Wednesday, January 27th, 2010

.

We’ve received numerous calls from HVAC contractors about the new HERS Refrigerant Charge Test procedures for new residential HVAC installations and change-outs.  There is a lot of confusion about when these tests are required and what steps the HVAC installer needs to take prior to the HERS rater arriving at the jobsite to perform the refrigerant charge verification test.  The rules are pretty straightforward but will require the HVAC installer to have a system and procedures in place so the the process goes smoothly without causing delays.

.

Title-24 HERS Refrigerant Charge Verification is required prescriptively in most of the California Climate zones.  However in the coastal climate zones it is not required prescriptively but can be used as a compliance credit in the Title-24 compliance run.  Either way the HVAC contractor will know that the refrigerant charge verification test is required if it is documented on the Title-24 compliance report Certificate of Compliance (CF-1R)

.

Here is a basic overview of the steps.

.

Step 1: Properly charge the system with refrigerant.  HVAC installers are required to properly charge the system and detail the results on the new Title-24 CF-6R certificate of installation.

.

Step 2: Provide access holes in the return and supply plenum for the HERS rater to perform the adequate airflow and  and the non-intrusive temperature split and static pressure measurements (see diagram below for access hole locations)

.

Step 3: Provide the the HERS rater the detailed HVAC equipment specs including specs for the air handling unit.  This information will be documented on the same CF-6R form that was used to document that the proper refrigerant charge was installed.

.

Step 4: Coordinate with the HERS rater.  The HERS rater will need your completed and signed CF-6R form prior to coming out for the refrigerant charge test.  They will also verify which diagnostic method you would prefer; the intrusive method (pressure gauges installed on the system) or the non-intrusive (STMS sensors and access holes for readings using temperature probes).  If the non-intrusive method is preferred then the HVAC installer is also required to install and have available STMS (Saturation Temperature Measurement Sensors) either factory installed or field installed according to the manufacturers specifications.

.

Step 5: HERS rater verifies the proper refrigerant charge and airflow over the coil and documents the results by uploading to the CHEERS (California Home Energy Efficiency Rating System) website and generates a certified CF-4R which is provided to the HVAC installer, building department and homeowner.

.

Some HVAC installers have expressed reluctance in having a HERS rater attach their own pressure gauges to the HVAC equipment for the test.  An alternative is to coordinate with the HERS rater so they are present during the initial refrigerant charge performed by the HVAC installer and can simply observe the pressure gauge readings and verify that they are in compliance with the Title-24 RA3.3-2 tables.   If the refrigerant charge meets these target numbers in the tables the HERS rater simply documents this on the CF-4R form.  However the HVAC installer will still be required to complete and sign their CF-6R certificate of installation and submit this to the HERS rater.

Saturday training webinar for building officials

Wednesday, October 28th, 2009

We’ve received a number of suggestions for our Title-24 training seminars including the suggestion to have a Saturday webinar for building officials, plancheckers, inspectors who are usually unavailable during the week.  We’ve scheduled our first Saturday afternoon webinar for November 28th from 1pm to 4pm.

This on-line Webinar class addresses the two most significant new changes to the residential Title-24 lighting & ventilation code.  As some of you are aware of the new 2008 Title-24 Building Efficiency Standards have been adopted in California and take effect January 1, 2010.  Two of the most sweeping changes involve residential indoor and outdoor lighting requirements, particularly kitchen lighting and the new adoption of ASHRAE 62.2, the requirement for residential mechanical ventilation for new construction and additions.

Title-24 Title-24

Residential Lighting requirements:
New restrictions, control requirements, high efficacy fixture requirements and incandescent allowances, and interior lighting worksheets will add an additional layer of complexity to residential lighting design.  This class will bring you up to speed on the new changes and address the underlying principles, calculation methods, strategies to assist you in complying with the new code changes and take you step by step thru the new WS-6R lighting certificate of compliance which must be filled out before the final certificate of occupancy will be issued. You will also understand which fixtures will comply as high efficacy (not all LED fixtures are certified as high efficacy), the new lighting control requirements for each room type and the new fixture and control requirements for residential outdoor lighting.

Title-24, Title-24

Residential mechanical ventilation requirements:
California has now adopted the requirements of ASHRAE Standard 62.2-2007 which means that starting January 1, 2010 all low-rise residential buildings are required to have whole house ventilation and satisfy other requirements to achieve acceptable indoor air quality.  You will learn the acceptable methods for satisfying outdoor fresh air requirements, and how to fill out the new certificates of installation forms.

Title-24 Title-24

Learn from Mark Madison, one of the leading experts in California’s Title-24 Building Efficiency Standards, a state certified Energy Plans Examiner, Certified Energy Analyst, HERS rater, HERS PV rater, Greepoint rater with over 25 years experience with building energy code compliance.
