Cf 1R Alt Form PDF Details

The Prescriptive Certificate of Compliance: Residential CF-1R-ALT, specifically designed for residential alterations, is a comprehensive document that facilitates regulatory adherence for construction projects undergoing modifications. This form, divided into five detailed pages, ensures that altered structures comply with the mandatory energy efficiency standards set forth by regulations. It caters to a wide range of projects, including single and multi-family homes, by covering essential aspects such as the building's envelope, fenestration, roofing, HVAC systems, duct and water heater replacements, and insulation values for opaque surfaces. Crucially, it distinguishes between alterations involving the opening of framed cavities for insulation installment and the complete replacement of structural assemblies, directing the application of specific insulation values accordingly. Furthermore, the document extends its utility to calculations related to fenestration areas, roofing product requirements, and special features like slab insulation and thermal mass. HVAC and water heating systems also receive thorough attention, specifying minimum efficiency standards and insulation requirements. The form concludes with a section on HERS (Home Energy Rating System) verification, underscoring the necessity of compliance checks for duct sealing, system replacements, and refrigerant charge measurements. Embedded within this structured approach is a flexible yet precise mechanism for ensuring energy efficiency in residential alterations, balancing prescriptive mandates with tailored project details. This blend of specificity and adaptability makes the CF-1R-ALT a crucial tool for navigating the intricacies of sustainable construction practices in residential alterations.
