RED Calc Free and Pro Tools Available

RED Calc Free and RED Calc Pro

Now that both RED Calc Free and RED Calc Pro are available, you can check them out and compare them for yourself. A great place to get a glimpse of RED Calc Pro is in the RED Calc Pro Manual. Many features of Pro are not included in Free, but some are very similar. Two of these are context-sensitive pop-up help, and math on-the-fly.

Context-Sensitive Pop-Up Help. When using both the Free and the Pro tools, clicking on any input or result label triggers a dialogue box explaining the label. This gives you detailed information when and where you need it. When you are done with the help dialogue, simply click outside the dialogue box to get back to your calculations. Below in Figure 1 is a screenshot of the RED Calc Pro 62.2-2016 tool showing the Pop-Up help for Floor area.

Math On-the-Fly. When you are using RED Calc Free and RED Calc Pro, you don’t need an extra calculator or your smartphone for side calculations, such as floor area; just use math on-the-fly! This time-saving feature allows you to use simple math notation to perform calculations within most input boxes of our RED tools. The available mathematical operations include +, -, *, /, and “( )”; or addition, subtraction, multiplication, division, and parentheses.

RED Calc Free allows math on-the-fly in most input boxes similar to Figure 2, below. The calculated floor area, equaling 2,200 square feet, appears when you click outside of the Floor area input box. If you need to edit the calculation, click back in the Floor area input box and change whatever you wish.

Math on-the-fly for RED Calc Pro allows all the same math entries, but you must turn it on to use it. When the math on-the-fly button is off, it activates the numeric keypad on your mobile device, but if it’s on, it does not.

Figure 3 shows the RED Calc Pro 62.2-2016 section of Floor area with the math on-the-fly feature turned off. Figure 4 shows the math on-the-fly feature turned on, indicated by the blue button.

Figure 4. RED Calc Pro math on-the-fly turned on for Floor area in ASHRAE 62.2-2016 tool. Notice the math-operations button to the left of the input box in blue, indicating it is turned on. When this button is clicked, it turns math on-the-fly on or off.

Context-sensitive pop-up help and math on-the-fly are very helpful and time-saving features of both RED Calc Free and RED Calc Pro tools. Make sure you use them often.
