SANSCalc Desktop Frequently Asked Questions In the Formula: A1 [S1 (CA × SH1 + CB × SC1) + CC × U1] is it correct that the variable S1 refers to Table 5, as per the text in the SANS204 document, section 4.3.4.2.3?

We have confirmation from SAIAT that in fact this is incorrect. For the variable S1 you need to use the SHGC value of the appropriate fenestration element listed in

Table 6 in the SANS204 document on page 14.

PLEASE NOTE : All SANSCalc versions have correctly used Table 6 in our calculations.

Is SANSCalc Agrément South Africa Accredited? We have recently received a number of similar questions regarding SANSCalc software being Agrément South Africa Accredited.  Here follows the explanation and answer to this question: Recently we attended a SAIAT's Energy Efficiency in Buildings workshop (based on SANS10400XA AND SANS204)  www.saiat.org.za We asked the lecturers about their thoughts on the SANSCalc calculator and they mentioned that they  are happy about any software calculator that would assist with the tedious 'deemed to satisfy" fenestration and other  calculations. They allowed us to hand out a SANSCalc brochure to all the attendees in the meeting. Their expert view is  that you don't need Agremént South Africa Accreditation for software that just assists you to do the standard "deemed to satisfy"  calculations as you can use Excel, SANSCalc, or your physical pocket calculators to do these calculations.   The only time you need Agremént South Africa Accreditation for your software is if you don't follow these "deemed to satisfy" recipes  provided within the SANS documents and that you then need software to prove your "rational design" so that your building  energy efficiency is equal or better than that of a similar building that do comply.   Software like Autodesk Ecotect fall into this 'rational design' sofware category as it can do sun and thermal analysis based  on location and orientation but at this stage Autodesk is not approaching Agremént South Africa for accreditation as Autodesk is  planning to build the functionality of Autodesk Ecotect into Autodesk Revit and then they will relook at the situation.   In a nutshell: SANSCalc do not need approval as it just uses the formulas from SANS 204 ( and SANS10400 XA)  to do the  fenestration calculations and so you can use it for your municipal submissions. If you want to vary from the SANS formulas  provided you'll need to either use Agremént South Africa approved software to prove your rational design (at this stage there aren't  any software applications approved) or use manual calculation to prove your compliance. Is SANSCalc compatible with ArchiCAD, or another CAD package, not from Autodesk? SANSCalc is a stand-alone product, for use with any CAD environment, however, there is an extra benefit for Revit users in that with the FREE Revit Add-on, available here. You can automatically import data for fenestration calculation purposes, to generate your reports for council submission. This is an added benefit for Revit users that saves even more time! How are the calculations done?  All calculations are based on the SANS 204:2011 Edition 1 and SANS 10400-XA:2011 Edition 1 documents published by  SABS and in accordance with the tables provided in the document. For more information about this or to purchase the  document please contact SABS on 012-428 7911 or go to www.sabs.co.za or www.sabs.co.za/Sectors-and-  Services/Services/Energy/index.asp Are all the SANS Energy Efficiency modules included? Yes. All the modules from the SANS 10400-XA and SANS 204 Energy Efficiency in Buildings documents have been  included. This software is subject to a yearly license structure, and all actively licensed customers will be entitled to all  updates, patches and fixes as they become available. Should you not be getting regular email notification of these updates,  please contact support@sanscalc.co.za and check in at www.sanscalc.co.za for more information and updates. Is there a trial version? Yes, you may download SANSCalc, and install it. It is important to follow the instructions accurately, as any deviation from  the installation path could negatively affect the operability of SANSCalc thereafter. Once installed please complete the SANSCalc activation request form, specifically requesting a trial version license key.  This will provide you with a 15 day trial to evaluate the software. What is the estimated time for the installation? The SANSCalc installation should take about 15 minutes at most depending on the Microsoft components download time.  Please refer to the Installation Instructions  document for guidance. It is important that these instructions are followed  accurately, as any deviation from the installation path could negatively affect the operability of SANSCalc thereafter. The  SANSCalc Revit add-in should not take longer than one minute. Where can I get training and training material required to operate SANSCalc? Some knowledge of the SANS 204 documents is recommended. We have released Getting Started Video Tutorials on the  SANSCalc Website outlining the functionality and work-flow of SANSCalc. Courses  are available through SACAP and SAIA, requiring Architects' attendance in order to achieve "competency" for municipal  plan submission. Having completed these courses, and together with the demo videos we've supplied on the SANSCalc  website, you'll require no further training in the use of SANSCalc. However, should you have any further questions, you are  welcome to contact the support team at support@sanscalc.co.za or the sales team at sales@sanscalc.co.za and we will  gladly assist you. I work on my PC and on my laptop when away from my office. Would the same licence work for both stations? SANSCalc licenses operate individually and will only work on the PC upon which you have installed and activated the  software.   Can we install SANSCalcExport on more than one PC?  Yes. For example, if you had 30 users, you could buy one SANSCalc License, install SANSCalc on a standalone PC, then  SANSCalcExport on the other 30 PCs. Each user could then export Revit info to a Database file, which could be opened  using the standalone SANSCalc PC. What happens if and when a new version of Revit is released? Is there an additional fee or am I able to upgrade with the  existing licence? SANSCalc is a stand-alone product, completely separate to Autodesk products. Updates and upgrades for SANSCalc are  not directly linked to Revit/AutoCAD, so anyone who has purchased SANSCalc will be entitled to any updates and new  versions free of charge for the duration of one year from date of purchase. We have adopted a time based licensing  system, currently available as 1 year licenses. Updates will be released regularly, as any amendments are made to the  either the software or the SANS 204 standard. The Revit add-on will be revised each year to cater for the latest available  release of Autodesk Revit, which will assist in transferring the parameters from Revit into SANSCalc automatically. This  add-in is optional and not required for SANSCalc to work. Does the initial purchase price include subscription? Yes, the initial price includes 1 year subscription which means anyone who has purchased SANSCalc will be entitled to any  updates, patches, fixes or new versions, free of charge for the duration of one year from date of purchase. An option to  renew your subscription after one year will be available at an additional fee, to ensure that you are only a download away  from always receiving the latest software. However if you opt to not renew your 1 year license the software will cease to  work after the 1 year has lapsed. Why is the price so low? We have reduced the price drastically to cater for our new license model which it is a yearly subscription based model. We  also have tried to make it as attainable as possible. We believe we offer the most complete software for the SANS Building  Energy Efficiency calculations Can I load SANSCalc on my MAC?  Yes, but with the use of Parallels or Bootcamp. Do I need the Internet to run SANSCalc, Desktop App? No, you do not, but you will need the internet in order to activate your software, via the activation page on the website, click here for activation.
