Indoor Carpet System ‘Carpet, carpet adhesive, or carpet cushion product installed on-site,
inside of the building’s weatherproofing system.’
Indoor Composite Wood or Agrifiber Product ‘Composite wood or agrifiber product installed
on-site, inside of the building’s weatherproofing system.’
Indoor Paint or Coating Product ‘A paint or coating product applied on-site, inside of the
building’s weatherproofing system.’
Infrared Emittance (As defined in SSc7.1) ‘A parameter between 0 and 1 that indicates the
ability of a material to shed infrared radiation. The wavelength range for this radiant energy
is roughly 5 to 40 μm. Most building materials (including glass) are opaque in this part of the
spectru, and have an emittance of roughly 0.9. Materials such as clean, bare metals are the
most important exceptions to the 0.9 rule. Thus clean, untarnished galvanized steel has low
emittance, and aluminum roof coatings have intermediate emittance levels.’
Infrared or Thermal Emittance (As defined in SSc7.2) ‘A parameter between 0 and 1 (or 0 and
100 percent) that indicates the ability of a material to shed infrared radiation (heat). The
wavelength range for this radiant energy is roughly 3 to 40 μm. Most building materials
(including glass) are opaque in this part of the spectrum and have an emittance of roughly
0.9. Materials such as clean, bare metals are the most important exceptions to the 0.9 rule.
Thus clean, untarnished galvanized steel has low emittance, and aluminum roof coatings
have intermediate emittance levels.’
In Situ Remediation ‘Treatment of contaminants in place using technologies such as injection
wells or reactive trenches. These methods utilize the natural hydraulic gradient of groundwater
and usually require only minimal disturbance of the site.’
Installation Inspection ‘The process of inspecting components of the commissioned systems
to determine if they are installed properly and ready for systems performance testing.’
Interior Lighting Power Allowance ‘The maximum light power in watts allowed for the
interior of a building.’
Interior Nonstructural Components Reuse ‘Factor determined by dividing the total area of
retained interior, nonstructural components by the total area of the interior, nonstructural
components in the completed design’ (as per errata Spring 2007).
Invasive Plants ‘Both indigenous and nonindigenous species or strains that are chara-
cteristically adaptable, aggressive, have a high reproductive capacity, and tend to overrun
the ecosystems which they inhabit. Collectively, they are one of the great threats to biodiversity
and ecosystem stability.’
Laminate Adhesive ‘An adhesive used in wood and agrifiber products (veneered panels,
composite wood products contained in engineered lumber, door assemblies, etc.).’
Landfill ‘A waste disposal site for the deposit of solid waste from human activities.’

Landscape Area ‘Area of the site that is equal to the total site area less the building footprint,
paved surfaces, water bodies, patios, etc.’
Life-Cycle Analysis (LCA) ‘An evaluation of the environmental effects of a product or activity
holistically, by analyzing the entire life cycle of a particular material, process, product,
technology, service, or activity.’
Life-Cycle Cost (LCC) Method ‘A technique of economic evaluation that sums over a given
study period the costs of initial investment (less resale value), replacement, operations
