(a) determine if all minimum LEED or NGBS measures required to be installed prior to installation of drywall or interior wall surfaces or prior to re-enclosure on insulated building cavities have been installed; and

(b) determine if air sealing measures are complete, if insulation is aligned properly within the air barrier, and if the air barrier and thermal envelope are continuous; and

(c) determine if insulation is installed in the building envelope and uniformly fills each cavity without gaps, voids, or compressions, has a continuous air barrier in contact with its surface, and is in substantial contact with either the interior or exterior sheathing material; and

(d) determine the number of LEED or NGBS points attributable to the following systems: foundation and framing materials; insulation; windows; doors; heating, ventilating, and air conditioning system; plumbing system; and site planning and preparation construction techniques used, including clearing, grading, soils management, and erosion and sedimentation control; and

(ii) after installation of all flooring, household appliances, heating, ventilation, and air conditioning equipment, plumbing, and electrical wiring, determine the number of LEED or NGBS points attributable to efficient use of natural resources, conservation of materials and resources, waste reduction, installation of environmentally responsible products, including, but not limited to, interior finish materials and trim, including paints and coatings; cabinets, casework, and carpets; yearly heating, ventilation, and air conditioning and hot water heating equipment efficiency; household appliances and lighting efficiency; and plumbing fixture efficiency.

(c) For a newly constructed residential building of three or fewer stories containing four or fewer dwelling units: if the residential building is not more than three stories in height above grade, and contains four or fewer dwelling units (not including a manufactured home or modular home), after construction of the building envelope is complete and after installation of all heating, ventilating and, if applicable, central air conditioners and associated pipes and ducts, a technician shall inspect such residential building to determine if the energy efficiency specifications and performance specifications prescribed by section 508.5 of this Part have been met.

(d) For a newly constructed residential building consisting of a newly constructed manufactured home:

(1) at the manufacturing factory, an on-site technician shall:

(i) determine if air sealing measures are complete, the insulation is aligned properly with the air barrier; and the air barrier and thermal envelope are continuous; and

(ii) determine if insulation is installed in the building envelope and uniformly fills each cavity without gaps, voids, or compressions, has a continuous air barrier in contact with its surface, and is in substantial contact with either the interior or exterior sheathing material; and

(iii) determine if factory-installed measures qualify for LEED or NGBS points, including measures prescribed by section 508.5 of this Part; and

(2) at the site of permanent installation of the manufactured home, a technician shall:

(i) determine if minimum LEED or NGBS requirements and the minimum site development activities with respect to the foundation and field-completed framing materials; heating, ventilating, and air conditioning system; plumbing system; and site preparation construction techniques used, including clearing, grading, soils management, and erosion and sedimentation control have been met; and

(ii) for components and seams not inspected at the manufacturing factory, determine if air sealing measures are complete, the insulation is aligned properly with the air barrier, and thermal envelope are continuous; and

(iii) excluding measures inspected at the manufacturing factory, determine if any additional energy efficiency and performance specifications prescribed by section 508.5 of this Part have been met.

(e) For a newly constructed residential building consisting of a newly constructed modular home:

(1) at the manufacturing factory, an on-site technician shall:

(i) determine if air sealing measures are complete, the insulation is aligned properly with the air barrier; and the air barrier and thermal envelope are continuous; and

(ii) determine if insulation is installed in the building envelope and uniformly fills each cavity without gaps, voids, or compressions, has a continuous air barrier in contact with its surface, and is in substantial contact with either the interior or exterior sheathing material; and

(iii) determine if any factory-installed measures qualify for LEED or NGBS points, including measures prescribed by section 508.5 of this Part; and

(2) at the site of permanent installation of the modular home, a technician shall:

(i) determine if all minimum LEED or NGBS requirements and the site development activities with respect to the foundation and field-completed framing materials; heating, ventilating, and air conditioning system; plumbing system; and site preparation construction techniques used, including clearing, grading, soils management, and erosion and sedimentation control have been met; and

(ii) for components and seams not inspected at the manufacturing factory, determine if air sealing measures are complete, the insulation is aligned properly with the air barrier, and thermal envelope are continuous; and

(iii) for components and seams not inspected at the manufacturing facility, determine if insulation is installed in the building envelope and uniformly fills each cavity without gaps, voids, or compressions, has a continuous air barrier in contact with its surfaces, and is in substantial contact with either the interior or exterior sheathing material; and

(iv) excluding measures inspected at the manufacturing factory, determine if any additional energy efficiency and performance specifications prescribed by section 508.5 of this Part have been met.

(f) For a substantially renovated residential building: a technician shall:

(1) after any improvements or restorations to, or substantial replacement of electrical, plumbing, or heating, ventilation, and air-conditioning systems, and after any removal of interior wall surfaces but prior to re-enclosure of insulated building cavities:
