|   In a peer study, *PowerCalc* was used to review the installation of a backup generator.   The electrical design for the installation specified ten (10) 112.5 kVA transformers. That's a lot of transformers, an oversight easily identified by a seasoned professional. This specification is about three times (3X) the amount of electrical power typically designed for such a facility (10W / SF instead of 3 W / SF).   Running the same design through *PowerCalc* resulted in a reduction of this specification for transformers instead to ten (10) 30 kVA to 45 kVA transformers. This "downsizing" resulted in over $2,000,000 in savings by not only reducing the size of the transformers, but also the related conductors and conduits.   For all involved in construction every day, these types of mistakes are not uncommon. These issues arise from the current electrical design practice of using "rules of thumb", makeshift spreadsheets, and software that "designs" from the *top-down* (*estimating* the total electrical load at the start of design). The accurate design approach is to instead know the* actual* electrical demand load by adding electrical loads from the circuit to the facility's connection to the power grid (*bottom-up*). This *bottom-up* approach is *PowerCalc's* patented design methodology.   In contasting approaches,* guestimating* the size of the electrical load in conjunction with pre-sets for panelboard sizes, transformers, equipment disconnects, feeders, and overcurrent protection devices at the start of the project may lead to an *inaccurate* baseline on which to build the electrical engineering design instead of an *accurate *calculation of the *Total Electrical Load* based on the project's *actual* electrical demand.   This distinction in approach is important as electrical equipment that is (1) *oversized* results in increased costs for the developer and/or owner for expensive electrical equipment as well as wasted electrical energy and (2) *undersized* results in a potentially increased risk to safety (fires).   *FYI: the initial design was done by an engineering consulting firm ranked in the top 100 nationally using leading electrical design software with a top-down design approach.*    ********************************************************************************************************* Join us for a Free Demo of  *PowerCalc -  *the 1st automatic electrical engineering design software in the cloud for* compliance with the NEC* and with simultaneously generated *1 Line Diagram*!   When: Friday,  April 9 at 12:00 PM Eastern Time (US and Canada)  Sign Up: [FREE Demo Friday, April 9 at 12 EST](https://us02web.zoom.us/meeting/register/tZwkc-qrrTguE9WcZGg6p62rw984s9O3MKgA?utm_source=hs_email&utm_medium=email&_hsenc=p2ANqtz-8MmNVbNgTzHfZO9X_4YvcIvVlpdcpPHdgCNJLIO2OP3cCHIOuLbJrtbWZqncAJLYkg11P1)   After sign up, you will receive a confirmation email containing information about joining the meeting. You can also see our most recent demonstration on video: [PowerCalc Demo: July 10, 2020](https://youtu.be/gDQgCOu2_LA?utm_campaign=Save%20Energy&utm_source=hs_email&utm_medium=email&_hsenc=p2ANqtz-8MmNVbNgTzHfZO9X_4YvcIvVlpdcpPHdgCNJLIO2OP3cCHIOuLbJrtbWZqncAJLYkg11P1)     Our software is a fully integrated design application that *saves* you *time* and *money*. This is *PowerCalc*...an incredibly powerful tool that's unexpectedly easy to use for compliance with the NEC.  |
