Inthe Energy Policy Act required the Dept. Additionally, the International Energy Conservation Code registers compliance with This inflection point begs the question: What makes a building truly energy efficient, and how does one quantify it? Cool roofs are now required in climate zones 1 through 3, while building orientation will play a larger role as well. Additionally, the early integration of architecture and mechanical, electrical, plumbing MEPand fire protection engineering will be inevitable to achieve compliance and optimal envelope performance.

This will further reduce cooling loads and take advantage of southern solar gains when the sun is low in the sky during the winter months, while being able to more effectively shade the high summer sun. Assemblies, such as curtainwalls, must be rated to limit air leakage to 0.

Automatic daylight controls are required in any space adjacent to a window sq ft or larger. Though more significant changes are expected in the edition, the minimum insulation values for opaque assembles have also increased, depending on the climate. This can be achieved through lower static pressure duct systems, which translates to fewer bends, wider ducts, and shorter runs—all of which impact architectural space planning.

Top 5 Things to Know About ASHRAE 90.1

Additionally, individual variable air volume VAV fans with motors greater than or equal to 10 hp need a variable speed drive VSDor another means of reducing fan power consumption. This effectively encourages HVAC designers to look toward a dedicated outside air systems DOAS in commercial spaces, as well as likely eliminating constant volume systems for hospitals and labs.

Employing separate perimeter heating, or finned tube radiation, is another simple way to meet this requirement. This applies to air conditioning units 4. A waterside economizer may be able to be substituted to achieve the same result.

Duct work higher than 3-in. Minimum performance requirements of heating and air conditioning equipment, including chillers, boilers, and packaged equipment, continue to increase from the previous standard.

Designers must pay special attention to which path of compliance will be used when testing chillers with or without VFDs. While often employed in commercial HVAC design, This now effectively limits the use of centrifugal fans in cooling towers. From exit signs to parking garages, artificial lighting and the lack of it continues to gain efficiency with Previously used to add efficiency, daylighting is now required in many spaces in the prescriptive path. Daylighting controls are now required in projects larger than 50, sq ft, while more sophisticated occupancy sensors are required for training rooms, lecture halls, and storage rooms 50 to 1, sq ft.

Automatic shut-off is required, with the exception of patient care areas, spaces where lighting is required for hour use, and where automatic shut-off would be unsafe.

Functional testing of all of these controls is also now required. Fifty percent of V outlets that serve private offices, open offices, and computer classrooms must be provided with automatic receptacle control. Buildings are encouraged to put parasitic loads i. To reach the next level of performance, efficiency requirements must trickle down to building inhabitants and their behaviors. How people interact with the building and how process loads are handled in the building will all be crucial to the success and compliance of ASHRAE To do a whole lot better than David P.

Callan is senior vice president at Environmental Systems Design, where he oversees the management of the technical staff in the design of high-performance projects. His experience includes the design and analysis of building systems and energy-saving measures for new and existing buildings worldwide, as well as the research and development of analysis techniques for new building technologies.

This is different than the Appendix G simulation, often used in calculating U.

Over the last two summers, I've taken the two stats courses meant to prepare future AP Stats teachers. Those courses were invaluable to me and gave me the confidence I needed to tackle a difficult subject.

I would like to thank you for offering such a chance for people to extend their knowledge in the fields of statistics, and consequently provide them the adequate tools for better performance and sound achievements in their jobs and research.

As a SAS programmer, I believe I will continue to use SAS for data manipulation but will utilize R when running models and exploring large data sets. I took the course to get starting using R, thus I think this will help with my use of statistics in the future.

I really think these online courses are great. I need to know R to perform my job as I am a product manager for a software company that interacts with R. I am now able to understand R scripts and hopefully contribute some of my own. The instructor's videos were great. Just hearing his voice made it more personal. This was my first ever web based course and I really enjoyed it although I had to work hard. I will be using this knowledge in my daily work. It was really interesting and useful.

This was one of the best statistics. I'm basing this comment on the online active text and video components - very clear. Great support from Professor and Teaching Assistant. Loved every single thing about this course and its content. My organization is slowly embracing predictive analytics outside of our environmental concerns, so this course contributes directly to strengthening my R toolkit. More and more medical students are submitting systematic reviews and associated meta-analyses, to meet research exposure requirements, in the Basic Sciences Programs of their medical school education, here in the Caribbean.

The course provided me with a unique and much appreciated opportunity to learn much more about the technique, its underlying principles, and how to correctly apply the tool whenever evaluating a collection of primary studies. Time and energies committed to the course have been very well spent. After trying to learn meta-analysis from various texts (e. It made the selection of fixed-effect or random-effects models much easier to understand, and the presentation of the math was very straightforward.

If I could write a book, I would want to do it this way. Each chapter was short and to the point. Not a lot of extras, but a sufficient number of worked examples to make it work. The software is very easy to use, and I appreciate the continual improvement that seems to be made. You and your colleagues have done something incredible here. It will help me gain confidence with conducting data analysis using R. I have tried a few R MOOCs in the past which helped me start out using R but I had not found a comprehensive intro to R that I could use more broadly - this course really succeeds with accomplishing that.They've posted a number of free new SAT practice tests.

Start there to get a sense of what the new SAT Reading section is like.

Listen to mercer frey glitch

Still have old SAT prep books sitting around. You can use old SAT Critical Reading questions to practice, but focus on the passage-based questions and ignore the sentence-completion questions.

Python file read

ACT Reading section questions will also be helpful, as they are all passage-based and contain vocabulary in context as well as logical progression questions. Another unlikely but helpful source is ACT Science questions.

ACT Science also has you break down charts, graphs, and evidence. If you can do well on ACT Science, you will be able to do well on the new SAT data reasoning questions.

Check out some sample questions over the Law School Admissions Council website. Want a bit more structure for vocabulary in context. One of my favorite tools for learning vocabulary in context is a browser app called ProfessorWord. This article alone has about a dozen SAT vocabulary words, according to ProfessorWord.

The writing section is quite different on the new SAT. There is more emphasis on logic and expression of ideas, higher-level writing skills, and punctuation.

This means that there are fewer grammar rules tested in isolation, which in turn means fewer "gotcha" questions on the new SAT Writing section. However, being aware of writing style, construction, and organization is more important, since you will now be working with longer passages.

Start your studying by learning English grammar rules by heart. Then give the SAT's official practice tests a try. In terms of additional practice questions, we recommend you use ACT English practice questions, as these are all passage-based, like the new SAT Writing questions are. You can also use old SAT Writing multiple-choice questions to test your grammar rule knowledge, but remember to be ready for passages. Finally, the more you read and write, the better you will get at spotting writing organization and style naturally.

The essay score is now completely separate from the writing score. The essay is now 50 minutes long instead of 25. You have to analyze how an author builds an argument in a passage (the passage will be part of the prompt). So you have to read the passage and write about it analytically during that 50-minute period. As we've mentioned, you should check out College Board's new SAT practice tests first to see real examples of the new SAT essay.
