MJ8 produces equipment sizing loads for single-family-detached homes, small multi-unit structures, condo­miniums, town houses and manufactured homes. This new version incorporates complete MJ8-AE volume in a user friendly format. It provides quick supplemental details and advanced topics as well as supporting reference tables and appendices.

• 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 estimating 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 glazing material, curb con­struction and light shaft construction
• Heat gain sensitivity to roofing material, roof color and the use of radiant barrier
• 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 any other types of walls and insulation options
