Residential Load Calculation Manual is your definitive, practical guide to understanding, calculating, sizing, and documenting the heating and cooling loads of modern residential buildings - explained in plain language, proven with step-by-step worked examples using real numbers, and current to every code, technology, and regulatory reality defining residential HVAC design in 2026 and beyond.
This book was written for you if you are:
- An HVAC contractor who needs to produce accurate, permit-ready Manual J calculations and win more business with documented professional work
- A licensed engineer catching up on a decade of change - heat pumps, SEER2, A2L refrigerants, and the NEC 2026 - in one authoritative read
- An architectural designer who needs to understand how every envelope decision drives mechanical system size and cost
- A HERS rater or energy auditor who verifies residential HVAC systems and needs the deepest technical foundation available
- A high-performance home builder designing Passive House, LEED, or net-zero projects where load calculation accuracy is not optional
Inside, You Will Learn How to:
- Calculate heating and cooling loads step by step with real numbers, room by room, using the complete Manual J Eighth Edition methodology - and permanently eliminate the oversizing epidemic that wastes money and comfort on most projects
- Apply the A2L refrigerant transition (R-32, R-454B) to equipment selection - the charge limits, UL 60335-2-40 safety requirements, leak detection rules, and installation planning the 2025 EPA mandate now requires
- Master every envelope load component - walls with thermal bridging correctly accounted, fenestration with NFRC whole-window values, below-grade assemblies, vented and conditioned attics, and the specific calculation differences between ICF, SIP, mass masonry, and high-performance wood-frame construction
- Calculate infiltration correctly using blower door ACH50 measurements and the LBL conversion model - and add the ASHRAE 62.2 mechanical ventilation load that represents thirty to forty percent of heating load in tight modern homes but is omitted from most calculations
- Size duct systems with Manual D methodology that delivers the right airflow to every room - and calculate the duct heat gain and leakage losses that make equipment sizing larger than the room loads alone would require
- Perform cooling load calculations using the CLF/CLTD dynamic methodology, correctly identify the hour of peak total load, and separate sensible and latent components for accurate equipment selection under Manual S
- Specify variable-capacity inverter-driven heat pumps using the modulation range strategy that neither undersizes for peak conditions nor creates short-cycling at mild conditions - the two-constraint problem that single-speed sizing approaches completely miss
- Design for net-zero energy, Passive House, LEED, and ENERGY STAR certification - where loads so small that standard equipment minimum capacity creates its own oversizing crisis, and where every input error is amplified without the conventional building's margin for error
