Build your own ACCA Manual J load calculations and energy models Brian Hayden Back in the 80’s ACCA created Manual J as a process to do load calcs. It was hundreds of pages of calculations, formulas, factors etc. Then in 1985 the first software was developed following Manual J to speed up the process. Over the decades, Manual J has become the industry proven method for load calculations & sizing HVAC equipment. Manual J calculations are everywhere now. They are a requirement to access rebates and professional certifications. Paying someone to do ACCA Manual J calculations costs thousands of dollars and can delay your project. Learning to build your own Manual J load calculations and energy models from scratch saves money and puts you back in control of your projects. “Manual J Load Calculations & Energy Modeling” is software-agnostic course. You can take this course and use any Manual J software program to do your calculations. This is a super-popular workshop that Gwen St. Sauveur has offered at conferences like NESEA’s “Building Energy” and Efficiency Vermont’s “Better Buildings by Design”. 👇 What Manual J is…and what it isn’t ACCA Manual J energy modeling is synonymous with doing load calculations. Manual J is not hydrothermal energy models, life cycle cost analysis models, BIM modeling, power system modeling etc… there are a bunch! But Manual J is definitely becoming the most popular and honestly could/should be done for every construction project today – be it for decision making, code compliance, tax incentives, utility rebates or green building program certifications! Already an essential design tool, energy models are used for code compliance, utility incentives & green building certifications. As we move towards a resilient, sustainable & emission free future, energy modeling should be used as a tool for decision making. Not only for sizing equipment but also for shaping buildings & selecting materials as well. As our buildings get tighter, creating accurate Manual J energy models must be accessible to all industry professionals. In this technical presentation attendees are provided the tools & training to create Manual J energy models of their own.
