The upcoming 2013 Title-24 Building Efficiency Standards were approved by the California Energy Commission on May 9, 2012. The new Title-24 energy code incorporates significant changes that will affect architects, builders, contractors, energy consultants, and solar PV installers. This class will review the upcoming changes to the energy code and the impact on building design along with compliance strategies that will allow you to comply with the new, stricter energy code cost effectively.
Mark Madison is a Certified Energy Plans Examiner, Certified Energy Analyst, HERS rater, and serves on the board of directors of the California Association of Building Energy Analysts (CABEC).
Starting January 1, 2010 the new 2008 Title-24 Building Energy Efficiency Standards became law in California and is roughly 15-22% more restrictive than the 2005 Title-24 energy code it replaced.
In addition, most utility incentives and many cities in California now require that you exceed the new 2008 Title-24 energy code by 15-35%! The big questions from architects, builders, and developers are these: How can this possibly be done? Is this a realistic, cost effective goal?
Our answer is simply this: Yes it can be done! And cost-effectively. This advanced Title-24 training class will examine new Title-24 compliance strategies and options which can take your project beyond the minimum Title-24 code requirements by 15%, 35% and more.
The course will provide a detailed understanding of all available Title-24 compliance strategies including HERS compliance measures, (duct testing, QII, refrigerant charge verification, etc) and how they can leverage your project into compliance with utility sponsored incentive programs, the New Solar Home Partnership (NSHP), LEED, and ensure quality control on the job site.
Architects who attend will receive (3) AIA CEU learning units (HSW & SD)

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

4 Impact of Time Dependant Valuation (TDV)
Bottom Line for 2008
Building designs that generate high heating/cooling loads during peak
energy cost periods will be severely penalized
Electric multipliers for 2008 up to 50 verses 20 in 2005 standards
Gas multipliers for 2008 up to 1.5 vs. 1.0 in 2005 standards
Upside: Energy saving features, strategies that reduce peak loads
are rewarded greatly, can help you go “better than” Title-24

119. Compliance Forms
CF-6R bottom line:
CF-6R forms a major part of Title-24 compliance
now. The real “teeth” in the new code.
Installation Contractors need to be familiar with CF-6R forms
CF-6R Installation Also will need to review CF-1R during bid process
Certificate to determine if any HERS measures will affect their
CF-4R Field work
Verification/HERS
Will require coordination between Designer,
Title-24 consultant and HERS raters
CF-6R forms filled out by hand will be unwieldy
because of requirements to file electronically
Will need a system to provide documentation

Registration Can use services of HERS raters to facilitate transmittal of
CF-6R to registry. However contractor is responsible for
content of CF-6R and must sign. HERS rater cannot
certify information on a CF-6R form.
The days of filling out CF-6R on the hood of contractors

Provide training to your installers for proper duct sealing, airflow, refrigerant
charge to minimize HERS verification failures
Prepare proper load calcs for every job and have documentation ready.
Will need system for providing access holes and labeling to avoid holdups in HERS
verifications
Be prepared to fill out electronically CF-6R for HVAC new and change-outs
Develop system to record and track CF-6R forms that will be needed later in HERS
process or incentive process
Develop good relationship with local HERS rater(s)
HERS rater cannot be part of your company in any way shape or form, cannot self-
verify. HERS raters are audited annually.

Building departments will need to set up access to HERS provider data registry.
Understand which documents required at plan-check and which are required at inspection
(CF-1R, CF-6R, kitchen lighting, CF-4R)
Forms are much more data intensive. Get familiar with new layout of forms and all the data that is
now required.
HERS measures now baseline. Submittals that comply without them should be reviewed closely.
Inspectors will need to be familiar with all of the CF-6R forms.
If registration required must be registered CF-6R forms, not filled out by hand.
Training on ASHRAE 62.2 highly recommended. Become familiar with ventilation calculation
methods fan/control features that satisfy this requirement. Important for on-site building
inspector, not at plancheck.
