BS Tools is a toolkit of calculators designed for HVAC and other Building Science (BS) applications, as an alternative to more tedious, manual methods.
UTILITIES
Single Point Psychrometrics:
This calculator provides psychrometric properties of air at a glance. It's great for changing humidity units.
Mixed Air Psychrometrics:
This calculator provides psychrometric properties of the resulting air of two mixed air streams, e.g. ventilation air mixed with return air.
Duct Calculator:
In a word, it's a classic 'ductulator'. This tool accepts any two choice inputs among CFM (Air Flow Volume), Duct Diameter, Friction Rate (Head Loss), and Air Velocity. This utility will then provide the other two parameters for you. Uses either a round diameter, or rectangular dimensions.
Smallest Zone Calculator:
This calculator can be used to gauge how much excess air is acceptable in a heating or cooling system.
Bypass Calculator:
Paired with the Smallest Zone Calculator, this can tell you how much air you can bypass. Values are unique for cooling and heating (adjustable for altitude).
IR Wall Insulation:
This calculator can help you estimate the R-Value of a wall, with Infrared (IR) exterior and interior surface, and interior ambient temperatures. Provides a common wall material that best matches your readings with a general degree of confidence in that match. Note included tips on measuring for best results.
Parallel R-Value:
This calculator provides an overall R-Value (and U-Value) for a wood frame building assembly* (typically a wall), given the R-Values of different materials and their areas or proportions present in the assembly. *Not for use with metal framing.
ASHRAE 62.2-2019:
Gives ventilation CFM requirements corresponding to ASHRAE 62.2-2019.
Fan Run-Time:
Simple calculator to calculate ventilation system run time, in min/hr, given the ventilation requirement and fan capacity. Pairs nicely with ASHRAE 62.2 Calculator (and is automatically linked).
Note:
The above calculators use IP (inch / pound) units.
Unit Converter:
Converts units.
Interpolator:
For when you have the number you're looking for at THIS point and THAT point but you're actually somewhere BETWEEN those points.
BS Tools is now free-to-try! You can install this app for free and use some of the utilities. You can decide at any time if you'd like to purchase access to the rest of the utilities permanently for a SINGLE, ONE-TIME fee. Regardless, there are no advertisements or intrusive pop-ups.
