I had recently written an article about the JADE W Economizer Controller explaining that the call for a new generation of controllers was due to a large number of economizer failures discovered in the field.

An economizer damper failure is a factor which would alarm the new generation Title 24 compliant controllers. An economizer employs dampers to deliberately separate air streams of different temperatures. When a damper does not close properly, or contains gaps, and leaks air instead of separating it; the temperature difference, and therefore the energy benefit is degraded.

This is especially noticeable during extreme temperature differentials. If the outside temperature is F during unoccupied mode, the last thing you want is a leaky economizer damper introducing frigid air into your HVAC system. Inversely, when hot air is leaked into the system, unnecessary cooling energy is wasted. Title Section The P rescriptive piece of Section Additionally, it requires a five year warranty on the economizer among other requirements.

Ultra Low Leak Dampers are not mandatory, only prescriptive. A Mandatory Title 24 requirement must be completed on each project. However, only fulfilling the mandatory requirements of a project is not sufficient. Prescriptive Title 24 requirements must too be included into the project to comply with Title 24 requirements.

Prescriptive requirements are a choice. However, the word choice here is a bit deceiving. Along with the mandatory requirements, you must complete all the prescriptive elements, including Ultra Low Leak Dampersunless you choose an alternative path to compliance called the Performance Method.

The Performance Method is more of an end result approach. As an example: hypothetically speaking, if ten prescriptive items are on the Title 24 list for a project, the Prescriptive approach would be to complete each and every one in accordance to the code.

However, that may prove to be the more expensive approach. The alternative is the Performance Title 24 method. This approach requires you to prove an energy goal has been reached to fulfill the Title 24 requirements for the job, regardless of how many Prescriptive tasks were accomplished.

Therefore, if you can prove a building is in compliance accomplishing only 8 of the 10 hypothetical tasks, you still receive certification. The use of Energy Commission-approved computer methods are used in the Performance Title 24 method. Detailed accounting of energy trade-offs between Prescriptive requirements are possible with this compliance approach. However, this approach will require more effort to meet the certification versus using a product which simply meets both mandatory and prescriptive requirements, such as the JADE Controlled Low Leak Economizer.

The energy budget for a proposed building is determined by applying the mandatory AND prescriptive requirements. The energy budget is the sum of the TDV Time Dependent Valuation — method for valuing energy in the performance approach of energy computed by Compliance Software certified for this use by the Title 24 Commission.

Title 24 offers a list containing a section of mandatory items, and section of prescriptive items. You have no choice but to complete all the mandatory items on the list. You have one of two options pertaining to the prescriptive items on the list. If you run a performance approved, Title 24 certified software program, it will analyze your building project, and offer a result of pass or fail.

If you pass the performance software results, you are done, no items from the prescriptive list needs to be completed; they are now elective items. If you fail, you must begin to integrate the prescriptive items until the software performance results are met. The strategy is to meet the software performance requirements by mixing and combining prescriptive items. Economizers provide huge energy savings, and the Ultra Low Leak Economizer assures the economizer will perform up to its calculated expectations.

Economizers provide free cooling when outdoor air conditions are suitable. This saves on mechanical cooling energy costs. The control system is very important to maximize energy savings.If you wish to purchase from us and are located in one of the excluded areas please contact us direct so that correct shipping charges can be figured.

Phasellus ultrices nulla quis nibh. Quisque a lectus loremus maximus.This is probably the most actively I've ever participated in an online class. I really benefitted from this course and I appreciate all the thought and effort put into making it such a valuable resource for R users. This course will definitely be used for my work. This course should be called Intro to R for Busy People.

I'm really glad I took this course and will recommend it to others. Thank you John and the TAs!. You've made my fear of R vanish-- the pace of the course definitely helped with building confidenceI took the course to get starting using R, thus I think this will help with my use of statistics in the future. Thank you for the excellent course. I appreciated the timely and detailed responses from Dr. Discussions initiated by other students were also very valuable - esp for PCA and ClustersInstructor gave good, understandable answers on the board, and several nice summaries of topics we were covering.

I have truly enjoyed this course with Professor Babinec. Anthony did a great job of answering questions, adding explanations and expanding on ideas. The best teacher I have had at statistics.

The course has fueled my desire to increase my understanding of measurement, specifically Rasch and IRT techniques and theories. This course helped me to learn more about Rasch analysis and Winsteps. I feel that this course taught me the how and why of what I see in my daily work. I like that there was detailed feedback for the assignments. The feedback was really helpful. This has given me a great overview of Rasch and introduced me to Winsteps which I will use instead of Quest in the future.

Thanks, the course was very useful and was very clear and well explained, especially for a beginner like me.
