Once you have created wall and glazing systems, the Building Assessment app is the next step to review your building envelope as a whole system, calculated using the methodologies outlined in Specification J1.5a Calculation of U-Value and solar admittance.
The Building Assessment app simply allows you to pull together the more detailed assessments you have already undertaken, with the results directly comparable to the ABCB Façade Calculator. The only difference between the ABCB Façade calculator and the Speckel Building Assessment app is that we take a more detailed approach to the design process, allowing real, verified specifications to be used as opposed to simply putting numbers into a spreadsheet.
Step 1 – Navigate to the Building Assessment app or your Project, Create a Design, give it a name and you are ready to go.
Step 2 – Next step… simply import an underlay (.PNG) of the building plan you would like to assess. These guys do a great job of converting from PDF.
Step 3 – Next, let's set up the CAD interface, by calibrating it to a know dimension on your plan and setting preferred snapping, direction and opacity settings.
Step 4 – Finally, select the Draw Zones tool and trace around your plane to nominate the areas of interest. Once you are complete, you will have collated all the areas required for the next step... nominating thermal performance values.
