Manual J Eighth Edition - Manual J is the industry standard residential load calculation method, required by most building codes around the country. Newly revised and expanded, the eighth edition procedures produce improved equipment sizing loads for single-family detached homes, small multi-unit structures, condominiums, town houses and manufactured homes. These procedures are also compatible with different types of comfort systems and applications such as:
A central single-zone comfort system
A central multi-zone system
A distributed multi-zone system
Dwellings that have limited exposure or no exposure diversity
More about Manual J 8th Edition:
MJ8 also accommodates homes that have exceptional architectural features and life style accessories such as:
Homes with large south-facing glass area or rooms with unusually large glass area
A thermally isolated solarium
Customized internal load estimates
MJ8 is sensitive to an increased variety of issues related to construction materials and methods including:
Fenestration loads for glass rated by the National Fenestration Rating Council (NFRC)
Improved duct load models
Improved methods for estimation the effect of internal and external shading devices, including insect screens
Infiltration estimated based on blower door test
Sensitivity to latitude and altitude
Sensitivity to skylight to roofing material, curb construction and light shaft construction
Heat loss and gain for log walls, structural foam panels, aerated autoclaved concrete block, insulated form concrete panels, brick walls, concrete walls, wood foundation walls, and many other types of walls and insulation options
NOW WITH NEW SOFTWARE: Each copy of MJ8 includes a demo CD containing software that demonstrates how a load calculation is performed using MJ8 as well as a fully-functional spreadsheet that makes it easier to learn and apply the Manual J method.

Duct Calculation Slide Rule - This durable two-sided plastic sizing wheel (or "ductulator") comes with a complete instruction manual for residential and commercial duct sizing procedures. Designed by Hank Rutkowski. Uses: - Sizes metal ducts, lined metal ducts, duct board airways, and wire helix flexible ducts - Converts round shapes to equivalent rectangular shapes - Correlates available pressure with total effective length and friction rate (Manual D sizing calculations) - Converts velocity into velocity pressure and vice versa - Corrects for altitude and temperature
MANUAL N Commercial Load Calculation - Manual N gives you a faster way to estimate heating and cooling loads for small and mid-size commercial structures, a simplified version of the procedure in the ASHRAE GRP 158 Load Calculation Manual. Manual N shows you how to use the Cooling Load Temperature Difference (CLTD) method to estimate heat gain through opaque surfaces and the cooling-load-factor method to estimate solar gains through glass. (120 pages) Topics include: - Basic principles of heat transfer, R-values, U-values, and heat transfer multipliers - Calculating loads for individual structural components, rooms, and zones - Time-of-day calculations - Peak room loads versus peak block loads - Indoor and outdoor design considerations - Sensible and latent internal loads - Wall, roof, ceiling, and partition heat gain and loss - Heat gain and loss from glass, ducts, infiltration, and ventilation - Humidification loads
