Editorial
The building sector has a strong potential to
help protect the environment and increase life
comfort and well-being.
Sustainable buildings meet the challenges of
the three sustainability pillars (People, Planet,
Profit) throughout their entire lifecycle.
At every stage, a building designed, built
or renovated in a sustainable way helps to
improve comfort and well-being, minimise the
consumption of natural resources including
energy, reduces the environmental footprint
and improves the project’s financial viability.
Buildings and construction work have the
largest single share in global resource use and
pollution emission. In OECD countries the
built environment is responsible for around
25-40% of total energy use, 30% of raw material use, 30-40% of global greenhouse gas
emissions and for 30 to 40% of solid waste
generation.
Demand for sustainable buildings is rising and
this can notably be seen through the development of building ecolabels all over the world.
The number of certified m2 has been increasing a lot over the past 10 years.
Standards, policies and regulations are
developing with an increasing emphasis on
the “lifecycle approach” designed to take into
account the whole building lifecycle: from the
raw material extraction to deconstruction and
recycling.
The building industry as a whole is moving
towards more sustainable construction.
A majority of architects, engineers, contractors, owners and consultants worldwide anticipate that a huge proportion of their work
will be “sustainable” in the future, and this is
not restricted to a geographic area or level of
development. Stakeholders have numerous
expectations and the market demands evidence of alleged “sustainable” performance.
In ISOVER, we are committed to foster sustainable construction.
ISOVER is the world leading supplier of
sustainable insulation solutions for all major application areas in both residential and
non-residential buildings. Our activities are
fully aligned with the objectives of the
Saint-Gobain CSR policy, and in particular of
its first area: “invent sustainable buildings”.
Together with other
Saint-Gobain businesses,
we demonstrate with the
Multi-Comfort program
that it is possible to design,
build and renovate
sustainable buildings using
our solutions. This program aims at minimising the environmental footprint of a building,
and focuses on comfort and well-being (thermal and acoustic comfort, indoor air quality,
visual comfort, safety…).
ISOVER trains and supports its customers to
achieve best ratings for their projects in the
different building labelling schemes (LEED,
BREEAM, HQE, DGNB…).
This brochure contributes to this education
effort.

Introduction
LEED® with Isover insulation solutions
What is LEED®?
LEED®, or Leadership in Energy & Environmental Design, is a green building certification
program that recognizes best-in-class building
strategies and practices. To be LEED® certified,
building projects have to meet certain prerequisites and earn points to achieve different
levels of certification. The prerequisites and
credits differ for each rating system, depending on the type of building (office, school,
home …) and the type of project (new or renovation). All in all, there are five rating systems
addressing multiple project types. In November 2015, there were more than 83,000 registered projects and 41,000 certified buildings.
The certification has been developed by the
US Green Building Council. As a platinum
member of this organization since September
2013, Saint-Gobain has become a key partner
of LEED®.
The USGBC released a new “V4” version of the
LEED® certification at the end of 2013. This
will be the only version on the market from
October 2016.
The LEED® V4 Building
Design and Construction
(BD+C) rating system for new
construction features eight
major areas, four of which
may be boosted by using
Isover insulation solutions
in the building design. For
some, the impact is quite
obvious, but for others using Isover insulation may not necessarily come first to mind!
Let’s discover together how our ISOVER sustainable insulation solutions can contribute in
this certification.

INTEGRATIVE PROCESS
Aim
To support high-performance, cost-effective project outcomes through an early analysis of the
interrelationships among systems.
Requirements
Beginning in pre-design and continuing throughout the design phases, the project needs
to identify and use opportunities to achieve
synergies across disciplines and building systems for Energy and Water-Related Systems.
For the “Energy-Related Systems” part, a
preliminary “simple box” energy modelling
analysis has to be performed before the
completion of schematic design that explores
how to reduce energy loads in the building
and accomplish related sustainability goals
by questioning default assumptions. At least
two potential strategies associated with site
conditions, massing and orientation, basic
envelope attributes, lighting levels, thermal
comfort ranges, plug and process load needs,
programmatic and operational parameters
need to be assessed.
Our contribution
By utilising BIM (Building Information Modelling), the objects and drawings for our products can help in the model development to
assess energy consumption, insulation values
and subsequently thermal comfort ranges as
well as anticipated operations and maintenance.
With decades of expertise in energy efficiency
and modelling, ISOVER can also support the
project team on the simulations, especially on
the insulation and air tightness of the building envelop, to help chose the appropriate
solutions.
Documentation available
BIM objects for our products and support
regarding energy efficiency calculation may be

AIM
To achieve increasing levels of energy performance beyond the prerequisite standard
in order to reduce the environmental and economic damage caused by excessive energy use.
Requirements
Three options are proposed. One option
consists in simulating the energy in a whole
building to demonstrate a % of improvement (for new construction) in the proposed
building performance rating compared to
the baseline rating (using the ANSI/ASHRAE/
IESNA standard 90.1-2010 to make the simulation).
A USBGC-approved equivalent standard may
be used for projects outside the USA.

ENERGY & ATMOSPHERE
Our contribution
10
Buildings account for some 40% of energy use
in the developed countries: there is a huge
savings potential in making them more energy
efficient. Heating and cooling account for two
thirds of buildings total energy consumption.
A large amount of this energy is wasted due
to a poorly insulated building envelope lacking
air-tightness.
Insulation is the most cost effective way to
reduce energy consumption in buildings and
cut associated greenhouse gas emissions.
The most inexpensive energy is the one that
is not consumed in the first place. It does not
need to be generated, imported, or paid for.
Naturally, this also doesn’t have any harmful
effects, neither on human beings nor the
environment.
Compared to an uninsulated building, an insulated construction ensures up to 80% reduction in energy consumption.
ISOVER insulation solutions help reducing
energy demand for heating and cooling and
reducing CO2 emissions.
ISOVER offers a large range of thermal insulation solutions meeting all the technical
requirements of the different applications in
residential and non-residential buildings, for
new build and renovation. Our solutions are
adapted for metallic or massive construction
buildings, wooden or steel frame constructions.
When combined with ISOVER highperformance mineral wool insulation,

MATERIAL & RESSOURCES
AIM
To encourage adaptive reuse and optimize the environmental performance of products and materials
Requirements
Four options are proposed for this credit:
1. Historic building reuse: maintain the
existing building structure, envelope and
interior non-structural elements of a historic building or building contributing to a
historic district (5 points);
2. Renovation of abandoned or derelict
building: maintain at least 50%, by surface
area, of the existing building structure,
enclosure, and interior structural elements
for buildings that meet local criteria for
abandoned or derelict buildings (5 points);
3. Building and material reuse: reuse or
salvage building materials off-site or on-site
(2 to 4 points);
4. Whole building life cycle assessment
(LCA): the LCA has to demonstrate a
minimum 10% reduction, compared to a
baseline building, in at least three of the
six impact categories (including global
warming potential). At the same time, no
impact shifting must be observed (i.e. no
increase by more than 5% compared to the
baseline building in another impact category) (3 points).
Our contribution
The product’s LCA results (reported in the
Environmental Product Declaration – EPD) are
necessary in evaluating the whole building’s
environmental footprint.
As a consequence, ISOVER is the best partner to ensure the three points of option n°4.
Indeed, ISOVER has been working on LCA
since the early 90s, and is one of the first
insulation manufacturers in the world to have
carried out a complete Life Cycle Assessment
of its products and delivered an EPD (Environmental Product Declaration) in compliance
with international standards. ISOVER EPDs are
verified by an independent third party for full
transparency.
In addition, ISOVER has implemented a program to improve the environmental footprint
of its products at every stage in their life cycle.
And this from the very beginning of the products conception, thanks to eco-innovation.
Eco-innovation is Saint-Gobain’s approach to
bring differentiating value to our customers
by developing and distributing innovative
products and solutions that help reduce
the environmental impact of buildings and
infrastructure over their entire life cycle, while
enhancing the comfort for the users. This is a
key aspect towards reaching the 10% reduction required to obtain this credit.

the project site are evaluated at 200% of their base contributing cost.
Our contribution
MATERIAL & RESSOURCES
Transparency on construction products’ environmental performances is a growing expectation in the building chain.
LCAs enable to avoid green washing and to
communicate credible, fact-based information
about products’ environmental performances. LCAs are the best science-based
tools to assess the environmental impacts
of construction products and buildings.
(EN 15804 and ISO 21930), a LCA calculates
in a rigorous and scientific manner the use
of energy, water and natural resources, the
emissions and releases into the air, ground
and water, and the waste generation.

LCAs are a powerful tool to help improving the environmental features of products through
Eco-Innovation. Considering multiple indicators over the entire life cycle allows avoiding impact
shifting (reducing one impact but increasing another) and a biased assessment.
MATERIAL & RESSOURCES
These inputs and outputs are calculated at each stage of the building life cycle. Results of LCAs
for different construction products can be consolidated to assess the environmental impacts of
a whole building.
our solutions
The principles of LCA are embedded in ISOVER
DNA. We have carried out our first LCAs in the
early 90’s. We are committed to promote the
use of LCAs in the building industry, to carry
out cradle to grave LCAs and EPDs according
to ISO 21930 or EN 15804 standards for all our
products, to use them in our Eco-Innovation
aproach and to communicate actively on the
results.
The results of our Life Cycle Assessments are
presented in the form of an Environmental
Product Declaration (EPD). To give confidence
in our communicated LCA results, we commit
to have our EPDs verified by an independent
third party. You can recognise ISOVER commit-
ments for Life Cycle Assessments and verified
Environmental Product
Declarations with the
“EPD verified” pictogram. This pictogram
lets you identify products with LCA results
available through third
party verified EPDs.
Our EPDs are product specific and made at
national level, taking into account the local
conditions, and are renewed every 5 years.

MATERIAL & RESSOURCES
Aim
To reduce construction and demolition waste disposed of in landfills and incineration
facilities by recovering, reusing, and recycling materials
Requirements
The project has to recycle and/or salvage non hazardous construction and demolition materials,
with the following options:
• Option 1: diversion of the construction and demolition material (50 or 75%);
• Or, Option 2: reduction of total waste material (no more than 12.2kg of waste per m2).
Our contribution
Regarding construction waste, ISOVER works
to reduce the amount of waste by offering
bespoke solutions to the installers, in order to
minimize the construction waste and cut-off
during the installation stage.
• Plastic packaging can be recycled if they are
not contaminated with other substances
such as waste paint, glue, etc.
Off-cuts during installation are limited and
can be shipped back for recycling.
Glass wool products have a very low wastage
rate (less than 2% for rolled products, around
5% for panels).
Regarding demolition waste, ISOVER insulation products are recyclable: ISOVER develops
waste management schemes to properly collect, sort out and process the end-of-life waste
to become new insulation.
Regarding the packaging waste:
• Pallets are untreated wood and can be
recycled;

integral organic-based surface
coatings, binders, or sealants.
Our contribution
The importance of good
air quality in a building
has long been recognised
in terms of its contribution to general health and
well-being. The best way
of providing the comfort
associated with good indoor air quality is
to reduce pollution from source, while also
improving ventilation and purifying the air.
The first step is removing or minimising emissions of primary and secondary pollutants at
source. ISOVER is continuously improving its
products to reduce formaldehyde and VOCs
emissions to the lowest possible levels.
Tested according to ISO 16000 standards,
ISOVER glass wool products release a very low
amount of formaldehyde and VOCs.
In several countries, ISOVER glass wool products are certified by independent institutes
according to low VOC emission rating schemes such as Eurofins in Europe or GreenGuard
in North America.
Our solutions
• ISOVER G3 glass wool products: volatile
organic compound (VOC) emissions have been significantly
reduced thanks to a new organic

Our contribution
Today’s world can
be a noisy place. The
sound environment
in which we live,
work and play is
busy and often even
disruptive. Good
acoustics can make
living indoors easier
and more enjoyable. And there are health and
well-being benefits for our bodies and minds
too... In order to block out environmental
noise the envelope must be effectively sound
insulated.
Carefully designed internal walls, floors and
ceilings prevent noise transmission within the
building. An efficient and carefully installed
sound insulation solution will protect against
noise over the entire life time of the building.
For many years the acoustic performance of
a construction was linked directly to density,
in line with the mass law. This is no longer
the case for insulation solutions based on the
mass-spring-mass principle. Using the mass
spring-mass principle we can obtain optimum
acoustic protection using lighter, thinner
constructions that are both quicker to install
and less expensive.
Besides having an environment free of sound
pollution, there are spaces (like classrooms,
conference rooms or opera halls) where it is
important to be able to hear sound clearly.
Each of these room types, therefore, requires a
special interior acoustic treatment to prevent unwanted effects (such as echoes) and
to create the right acoustic environment for
the activity taking place. The easiest way to
achieve this is to decrease the reverberation
time using sound absorbing materials.
Our solutions
The high performance of the ISOVER
lightweight mineral wool products (glass wool
and Ultimate products) makes them ideally
suited for use in mass-spring-mass systems
or for use as sound absorbing materials, thus
achieving outstanding acoustic results. In the
phase of construction planning special attention must be paid to the heating and ventilation system. By using ducts made of reinforced
mineral wool, such as ISOVER
CLIMAVER or by insulating
the metal ducts with mineral
wool, sound comfort can be
significantly improved.

INDOOR ENVIRONMENTAL QUALITY
Thermal comfort
To promote occupants’ productivity, comfort, and well-being by providing quality thermal
comfort.
Requirements
For all shared multi-occupant spaces, collective thermal comfort controls can be installed.
Thermal comfort controls allow occupants,
whether in individual spaces or shared multioccupant spaces, to adjust at least one of
the following in their local environment: air
temperature, radiant temperature, air speed,
and humidity.
INDOOR ENVIRONMENTAL QUALITY
AIM
The building has to be designed (heating,
ventilating, air-conditioning and building
envelope) to meet the requirements of specific
standards on thermal comfort (ASHRAE standard 55-2010 or ISO and CEN standards).
In addition, individual thermal comfort
controls must be provided for at least 50% of
individual occupant spaces.

Our contribution
People are spending more and more time
indoor and they expect to experience a level of
thermal comfort that enables them to perform their daily tasks efficiently and ensures
their good health and well-being. Although
thermal sensitivity naturally varies from one
person to another, the basic principles behind
thermal comfort are largely universal.
The design of an efficient building envelope is
key, as it acts as a filter between the exterior
and indoor climates.
Insulating the building envelop reduces heat
loss in winter and heat gain in summer.
It also reduces the “cold wall effect” that can
be experienced radiating from poorly insulating walls. Insulation keeps walls’ surfaces
warmer in winter, reduces condensation on
the sides and improves the temperature feeling in rooms (homogeneous temperature in
the living space). It helps to keep and maintain
a comfortable temperature in all points of the
building.
Besides adequate thermal insulation, the
building shell must be airtight to prevent the
uncontrolled flow of air, as leaky cracks and
joints will invariably cause uncomfortable
draughts.
Our solutions
ISOVER offers a large range of thermal insulation solutions meeting all the technical
requirements of the different applications in
residential and non-residential buildings, for
new build and renovation. Our solutions are
adapted for metallic or massive construction
buildings, wooden or steel frame constructions.
With the VARIO System, ISOVER has the ideal
range of products to make the building shell
perfectly airtight and protected against
moisture. The VARIO airtightness membranes
help regulate moisture in the construction:
they adapt to the climate conditions in order
to protect the building fabrics: in winter, the
membranes block the moisture generated
inside the rooms and prevent it from penetrating into building’s structure; in summer,
they allow the moisture to escape outside the
building structure.
In many countries, ISOVER facilitates the thermal modelling through Building Information
Modelling (BIM) available files.

Façade F4 is an innovation developed by ISOVER for low energy buildings (residential and offices).
It can be used for both new and renovation projects. It combines an external and internal insulation, combined with an airtightness system to provide the maximum comfort to the occupants, in the
minimum of space.

INNOVATION
Aim
Requirements
Project teams can use any combination of:
• innovation: by achieving significant, measurable environmental performance using a strategy not
addressed in the LEED green building rating system;
• pilot: by achieving one pilot credit from USGBC’s LEED Pilot Credit Library;
• and exemplary performance strategies: an exemplary performance point is typically earned for
achieving double the credit requirements or the next incremental percentage threshold.
Our contribution
Research & Innovation are at the heart of
Saint-Gobain ISOVER’s strategy, and sustainable
innovation too, thanks to the Saint-Gobain
Eco-innovation approach. Since its foundation
in 1937, Saint-Gobain ISOVER has made regular
investments in R&D. Our efforts focus both on
breakthrough innovations and on continuous
improvements, open and attentive to customer
needs.
Our R&D teams innovate in particular in the
following areas:
• Insulation materials: we constantly improve the
performances of our existing materials (glass
and stone mineral wool, insulation foams) and
develop new high performance insulation such
as vacuum insulation panels or aerogels;
• Sustainable insulation: we find new solutions
to reduce the environmental impacts of our
products over their whole life cycle: for instance
by developing formaldehyde free binders, by
reducing water and energy consumption as well
as air emissions in our processes and by recycling
waste;
• Systems and solutions: our strong competencies in building physics (thermal, acoustics, air
tightness, moisture management, air quality,
fire behaviour…) help to design new systems
and new solutions, easier to install and better
delivering the designed performances. ISOVER
develops complete insulation systems which
include laying and fixing accessories as well as
implementation recommendations and specifications;
Here are recent examples of innovations by ISOVER:
• Façade F4 (cf p.26);
• The CLIMAVER self-bearing insulated airconditioning duct systems are quick and easy to install.
They perfectly replace conventional insulated
metal ducts. They provide excellent thermal, fire,
acoustic and air quality performance;
• The ISOVER Multimax Lambda 030 glass wool is
the mineral wool product with the best thermal
performance on the market. It offers the same
thermal resistance as the other mineral wools,
but with a lower thickness;
• Xtra simple. Xtra safe. Vario Xtra. The new
airtight and moisture control Vario Xtra system
expands design possibilities and offers improved
safety from moisture. The new Vario Xtra range
offers a wide variety of efficient solutions for
pitched roofs, timber frame walls and flat roofs.
ISOVER insulation solutions can also be an asset for
the following pilot credits:
• Enhanced acoustical performance - exterior noise
control;
• Green training for contractors, trades, operators
and service workers.

This brochure only provides an indication on the possible credits
which our insulation products could yield in relation to a LEED rating
system. It is intended as a guide in the choice of appropriate insulation solutions in relation to the LEED credit rating system and has
no binding value. The LEED credit rating of a project is influenced by
a variety of factors, such as the type of building, configuration of all
the other elements of the building in addition to the insulation, final
configuration of the insulation itself, etc… The final rating is subject
to the performance of a LEED assessment as per the LEED methods
and procedures available on their site. It is the user ‘s responsibility to
choose the appropriate building environmental assessments methods
destined to ensure that the building meets regulatory requirements
at national, local or regional level.
