Currently, only Manual J is available. Most of our users download and fill out the free ACCA Speed Sheets for Manual S and Manual D (https://www.acca.org/standards/speedsheets). They are Excel based templates that are fairly easy to fill out by hand. Almost all of information for the Manual S worksheet is copied from the Manual J report. The remaining information you will need is the latent, sensible and heating outputs of the equipment you are proposing to install. This information can typically be found in the manufacturer's product data guide.
