HILTI FIRESTOP PRODUCTS AND “GREEN” BUILDING CONSTRUCTION
“Green” building projects are becoming increasingly popular in today’s construction market.  This is
why the number of Green buildings certified and registered by the Leadership in Energy &
Environmental Design (LEED™) Green Building Rating System has dramatically increased over the
last few years.  As of early 2005, there are more than 1,500 large construction projects across all 50
states that are LEED™ certified and registered.
The Leadership in Energy and Environmental Design (LEED™) Green Building Rating System
represents the U.S. Green Building Council’s effort to provide a national standard for what constitutes
a “green building”.  This consists of a voluntary rating system document that states the basic intent,
requirements and documentation submittals that are necessary to achieve each credit.  Projects earn
one or more points toward certification by meeting or exceeding each credit’s technical requirements.
Points add up to a final score that relates to one of four possible levels of certification.
The intent of LEED™ is to create a guideline for new commercial construction, major renovations and
high-rise residential buildings that are environmentally responsible, profitable and provide a healthy
place to live and work.
LEED™ is divided up into six credit sections, Sustainable Sites, Water Efficiency, Energy &
Atmosphere, Materials & Resources, Indoor Environmental Quality, and Innovation & Design
Process.
Each section has certain limits or minimums that must be met in order to receive a credit for a
particular section.
The section that is truly relevant to Firestop Sealants is Indoor Environmental Quality
Credit 4.1, Low-Emitting Materials, Adhesives & Sealants
In this section, the stated requirement is that the VOC (Volatile Organic Compound) content of each
adhesive and/or sealants being used on this project is below 250 g/l.   South Coast Air Quality
Management District (SCAQMD Rule #1168) and Bay Area Air Quality Management District
Regulation (BAAQMD Rule #51) is referenced in this section.
Credit 4.2, Low-Emitting Material, Paints and Coatings
In this section, the stated requirement is that the VOC (Volatile Organic Compound) content of
paints being used on this project is below 150 g/l for non-flat paints.  FIRESTOPS are not classified as
paints, although if an individual insist that firestop products be classified as such, Hilti Firestop
products do meet this requirement.
