visard Posted January 28, 2015 Share Posted January 28, 2015 I'm currently working on a zero net energy residence and would like to know if we have access to any tutorials, templates or worksheets to help assemble data for calculations? I have been looking at the worksheet formulas for wall and roof areas and am curious if any systems have already been developed. Other suggestions would be welcome. Thanks, Quote Link to comment
mike m oz Posted January 29, 2015 Share Posted January 29, 2015 Francois Levy's book BIM in Small-Scale Sustainable Design would be a good place to start. http://www.francoislevy.com/book.html More information: http://architosh.com/2012/07/architosh-talks-to-francois-levy-about-small-firm-bim/ Quote Link to comment
CipesDesign Posted January 29, 2015 Share Posted January 29, 2015 A few years ago I did a net zero home. The project was a great success. The house literally produced more energy than it used. Of course "end-user hands-on management" was partly if not totally responsible for that (read: the husband/client was particularly anal). And of course, the couple divorced within a year... But I digress. In that project we determined that we needed a specialist, a passive solar engineer, and he did all the calc's, using "Energy 10" software (I'm sure there are other such products now). It's a pretty complex system and I was more than happy to collaborate with everyone involved. Bottom line: You should seriously consider exporting your data to an energy calc program. It will tell you everything you need to know. Or, if you can afford it, find a specialist and let them do their thing! I'm not saying that you couldn't do it all in VW's, but I fear it will be a long and tedious process. Why reinvent the wheel?? Quote Link to comment
Christiaan Posted January 29, 2015 Share Posted January 29, 2015 It's a real shame VW doesn't include any design stage energy analysis that would assist us in making early design decisions. Are you following a standard Edward, such as PHPP (Passivhaus)? Quote Link to comment
bcd Posted January 29, 2015 Share Posted January 29, 2015 I remember the Japanese version of VW had something in the works for this. I wonder where this project is now? Quote Link to comment
visard Posted January 29, 2015 Author Share Posted January 29, 2015 Thanks for the responses everyone. To clarify - I have been studying with the NESEA and have completed my ZNE certification taught by Mark Rosenbaum,PE, who also teaches the PHPP certification classes. Mark kindly makes available to class members his proprietary software templates which are modeled on the PHPP standards. With these templates we, the students, complete a ZNE model as a final project, which I have completed. My question to the community goes to preparing a worksheet to compile date for use in my energy analysis. This would primarily be area for the house components, walls, roofs, slabs, window and doors, etc. I've read that we can construct a worksheet and use area calc formulas for gross and net areas and wondered, would I be roughing out a template from scratch or has VW provided anything of the sort. Thanks for your comments and interest, V. Quote Link to comment
Tobias Posted January 30, 2015 Share Posted January 30, 2015 Hello visard, I took that same class with Marc. Great class. If I remember correctly the information that you need is pretty basic. I did mine w/ vectorworks as well. I don't know if I made any worksheets to pull out the data or not, but I will check. If you search this board there is a lot of examples of people who have shared worksheets to do material take off of one kind or another. I would see if that turns up anything you could modify to your needs. I have often thought it would be great to set up VW to give me all the data for material take off and energy models, but I haven't been doing much design lately. There was a REScheck worksheet that someone created that used a combination of worksheets, records and classes to pull out the data need for rescheck, that might be a good place to start.

visard Posted February 9, 2015 Author Share Posted February 9, 2015 I have begun to assemble worksheets with area calculations: walls, doors, windows, thanks to the thread available here. I've been looking for a formula for glazing area - anyone know if that is available or how to format? Thanks, visard Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted February 9, 2015 Vectorworks, Inc Employee Share Posted February 9, 2015 It should be: =('Window'.'NGA2') But if someone here disagrees, they may know far better than I. Quote Link to comment
visard Posted February 9, 2015 Author Share Posted February 9, 2015 Thanks, Jim. Seems to work just fine, with or without the '' quotes. v. Quote Link to comment
michaelk Posted February 9, 2015 Share Posted February 9, 2015 The single quotes are only needed if there is a space in the name of the record format or field. But it's a good habit to get into. mk Quote Link to comment
Pat Stanford Posted February 9, 2015 Share Posted February 9, 2015 There is also a similar field for Doors. ='Door'.'NGA2' Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted February 9, 2015 Vectorworks, Inc Employee Share Posted February 9, 2015 There is also a similar field for Doors. ='Door'.'NGA2' My apologies, totally forgot, to calculate ALL the glazing, (which I would assume you need to if you're doing energy analysis) you'd need to combine both of these results.

Beth Globe Posted March 22, 2017 Share Posted March 22, 2017 Is there a way to modify the formula to include the rough stud openings? This is required in my area Thanks Quote Link to comment
Pat Stanford Posted March 23, 2017 Share Posted March 23, 2017 'Window'.'RoughOpenWIdth' 'Window'.'RoughOpenHeight' 'Door'.'ROWidth' 'Door'.'ROHeight' Quote Link to comment

Pat Stanford Posted April 19, 2017 Share Posted April 19, 2017 I just checked a round window. What you get it the rough opening width and height as linear dimensions (rectangle). I don't think there is a field that will give you the "cut out" area that the window will penetrate the wall. The Net Glazing Area appears to be correct. Quote Link to comment
