In SW Florida this one page calculation is recognized by building department plans examiners as a tried and true calc spreadsheet simplifying the permitting process. I want to thank the hundreds of ‘Users’ over the past 13 years that have sent me e-mails as far away as the University of Sciences of Saudi Arabia, inspiring me to continue to update for each code session. I remember as one of Mike Holts students in 1980, he taught this simple way of calculating by ‘Steps’ with each applicable code article. Here is how it works, In Step 1 by inserting area sq ft, number of small appliance and laundry circuits. A drop-down box has been added to convert from square feet to meters. For Step 2, As contractors suggested the calculator was expanded from 2 HVAC units to multiple quantities. Also a check box to select between Condensing Units or Heat Pumps. See the equipment set-up sheet tab on the bottom left to customize unit loads. Step 3, Insert the quantity of fixed appliances. Original loads were used from the average appliance loads for the GE appliance guide. Now you can customize HVAC and appliance loads by means of an equipment set-up sheet (this is found by the tab at the bottom left of your screen) with fixed and new entry cells (blue cells are fixed loads, yellow cells to insert your own personal entries). Step 4, insert number of household dryers Step 5, Range demand, with separate entries for column A & B appliances. In Standard mode you can enter the kW for one range or just enter the number of appliances for a Column ‘C’ demand. You can then calc a Col B demand (if applicable for kW) for these appliances and the calculator will select the smaller of the two load calculations. When using the “Optional’ calc with a Gas Range, be sure to use the check to box or the calculation will not total because it appears incomplete. I attached a ‘User Info’ sheet (this is found by the tab at the bottom left of your screen) added a personal company/corporate information, allowed this sheet to be set up, saved and used time and again. Holding your cursor over any cell with a RED marker in the upper right reveals comments or helps to guide you thru the data entry. Validation rules have been added as a helpful feature, try entering 1 for small appliance circuits, the validation is set for 2 minimum, by clicking on cell ‘ E6 ‘ the code article pop-up window shows the corresponding article. If the window is in your way just pull it to the side and keep entering. Press the ‘Tab’ to move from entry cell to entry cell. If you decide you want to change from calculating a ‘Standard’ calc (Art 220.42 thru 220.55) to an ‘Optional’ calc (Art 220.82), just check the box in cell D6 next to the title of the sheet, and your now working an ‘Optional’ Calc. The Neutral Calculation is always based on Art 220.42 thru 220.55 and not affected by the use of the ‘Optional Calculation’. Locally the AHJ were requesting that the pool equipment loads be shown with pool heat pumps calculated @ 125% as continuous loads (3 hours or more). This made for the addition of the lower section ‘Pool Feeder Calculation’. In this section the largest motor is calculated @ 125%, automatically a pool pump selected from the continuous drop-down box the VA is multiplied by 125%, if you then select a 3.5 or 5 ton heat pump, the heat pump becomes the largest motor and the continuous motor value changes to 100%. Other motors, like a sprinkler pump might be inserted from the non- continuous drop-down boxes. There are two other user entries for other loads (grill, landscape lighting, etc.) that can be names and loads inserted with check boxes for identifying neutral connected loads. Validation rules have been applied to minimize errors when entering loads and/or quantities. To print go to the top of the page, next to File , Edit, is View from there go down to Custom Views, I have set-up a 'calc w/ pool' and 'calc no pool'. Select the one you want to print and press the print button If you would like this spreadsheet to be modified to meet your own special requirements, Please e-mail me with your name and telephone number and I will schedule a time to discuss your needs, ecalc@comcast.net John Sokolik Tab !1 04/30/18 Company Name Company Name Address Address City, State, Zip Code City, State, Zip Code Telephone & Fax Telephone & Fax Serial Number !1 04/30/18 !2 04/30/18 !3 04/30/18 !4 04/30/18 !5 04/30/18 !6 04/30/18 !7 04/30/18 !8 04/30/18 !9 04/30/18 !10 04/30/18 !11 04/30/18 !12 04/30/18
