(b) For a newly constructed residential
building (not including a manufactured or modular home), regardless of height:
a technician shall:

electrical system, rough plumbing, the heating, ventilation, and air
conditioning system, and insulation, but prior to installation of drywall or
interior wall surfaces or prior to re-enclosure of insulated building cavities:
(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

(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:
