This declaration is an environmental product declaration (EPD) in accordance with ISO 14025 and EN
15804. EPDs rely on Life Cycle Assessment (LCA) to provide information on a number of environmental
impacts of products over their life cycle. Exclusions: EPDs do not indicate that any environmental or social
performance benchmarks are met, and there may be impacts that they do not encompass. LCAs do not
typically address the site-specific environmental impacts of raw material extraction, nor are they meant to assess human
health toxicity. EPDs can complement but cannot replace tools and certifications that are designed to address these
impacts and/or set performance thresholds – e.g. Type 1 certifications, health assessments and declarations,
environmental impact assessments, etc. Accuracy of Results: EPDs regularly rely on estimations of impacts, and the
level of accuracy in estimation of effect differs for any particular product line and reported impact. Comparability: EPDs
are not comparative assertions and are either not comparable or have limited comparability when they cover different
life cycle stages, are based on different product category rules or are missing relevant environmental impacts. EPDs
from different programs may not be comparable.

Colombia and are internally transported to the ES Windows facility for final fabrication into curtain walls. Once all
products have undergone quality inspection, the aluminum extrusion is cut to customer specifications and the frame is
assembled including the addition of a gasket and sealants. The finished Curtain Wall product is then packaged and
distributed to the customer.

Environment and Health During Manufacturing

ES Windows is committed to reducing its environmental impact and to the health and safety of its employees. Through
their core values, ES Windows places a responsibility to be accountable for their actions and interactions with the
environment and stakeholders. This is emphasized in the code of conduct which includes respecting human rights and
the rights of employees, in addition to protecting the environmental and surroundings through sustainable production
processes. To reduce energy consumption, ES Windows has installed a solar panel system to offset energy needed
from the local grid. To reduce water consumption, ES Windows uses water saving devices, monitors water
consumption use, analyzes and repairs leaks, and conducts awareness campaigns to make employees aware of
various sustainable objectives.

Product Processing/ Installation

ES Windows’ products should be installed by qualified contractors, adhering to best industry standards and according
to all applicable building codes in the local jurisdiction. The installation and use stages are outside the scope of this
EPD.

Packaging

Shipments of Curtain Walls are delivered to customers at the project site in cardboard packaging or wood crates. ES
Windows requests that customers dispose of the packaging materials in the appropriate disposal/recycling streams in
accordance with their local guidelines.

Reference Service Life

This EPD does not cover the product use phase and therefore makes no specific claim as to the typical reference for
service life.

Extraordinary Effects

Fire: No negative environmental impact will result from exposure to fire.
Water: Product contains no substances that would have an impact on water quality during a flooding event.
Mechanical Destruction: No danger to the environment can be anticipated during mechanical destruction.
Re-use Phase

Reuse or recycling of Curtain Walls should be considered where feasible.
Disposal

ES Windows products are not considered to be hazardous materials, so they may be disposed via typical, non-
hazardous waste stream classifications and disposable routes; nevertheless, ES Windows encourages the
repurposing of products due to their ease of reuse and reuse versatility. When not suitable for reuse, recycling options
are typically available and should be investigated rather than introducing the product to the waste stream. Aluminum is
100% recyclable and should be recycled where outlets are available. Glass is considered a non-combustible material
and is not suitable for waste to energy.

Estimates and Assumptions

The major assumptions for the development of this EPD are listed below:

• Ecoinvent v3.5 database with cut-off allocation processes is used as the primary database source for
conducting the LCA in SimaPro.

• Certain raw materials are not entirely modelled but selected from the ecoinvent v3.5 database.
• Certain materials, for which the Safety Data Sheet (SDS) was not provided, or which had missing components,

were modelled as proxy chemical compounds in approximation with similar products and/or best available
practices.

Cut-off Criteria

Processes whose total contribution was less than 1% of the product mass or contribute less than 1% to all considered
impact categories were excluded.

All material flows that exit the system and whose total contribution was more than 1% of the total impact in that impact
category were included.

For the processes within the system boundary, all available energy and material flow data have been included in the
model.
Background Data

Primary data was collected from ES Windows for the 2018 calendar year, representing the latest data available. Each
dataset used was taken from SimaPro databases, either ecoinvent v3.5, US-EI 2.2 or US LCI. These databases are
widely distributed and referenced within the LCA community and are either partially or fully critically reviewed.

Data Quality

Throughout the creation of the LCA models, a variety of tests and checks were conducted to ensure the highest of
quality of the completed analysis. Checks include an extensive review of the model and the background data.

Curtain Wall According to ISO 14025 & EN 15804
Self-Supporting Façade Elements

To ensure precision, completeness, consistency and representativeness of the data, first-hand industry data and
reliable LCI data from ecoinvent v3.5, US-EI 2.2 and US LCI databases were used. Processes and data used are
representative of the global geographical range and the standard or best available practices.

Period Under Review

First-hand industrial data collected from ES Windows is representative of ES Windows’ Curtain Wall production for the
2018 calendar year. However, data used from the LCI databases in SimaPro has a wide temporal range from 1979 to
2020.

Allocation

Unit allocation was used to determine the manufacturing inventory for window and door products. This methodology
was selected because the manufacturing process is primarily an assembly process and does not vary significantly
across products of different type, dimensions, or mass.

Comparability

A comparison can only be possible if all data sets to be compared were created according EN 15804 and the building
context, respectively the product-specific characteristics of performance, are considered.

Results

Results are reported based on characterization factors from the US EPA Tool for the Reduction and Assessment of
Chemical and Other Environmental Impacts (TRACI 2.1 impact categories). Additionally, impact categories taken from
the University of Leiden (CML) methodology are reported to facilitate the use of this EPD outside of North America.

Curtain Wall According to ISO 14025 & EN 15804
Self-Supporting Façade Elements

LCA results are presented per the declared unit (1 unit of Curtain Wall). Note that, at this point, the reported impact
categories represent impact potentials, i.e., they are approximations of environmental impacts that could occur if the
emissions would (a) follow the underlying impact pathway and (b) meet certain conditions in the receiving environment
while doing so. Life Cycle Impact Assessment (LCIA) results are therefore relative expressions only and do not predict
actual impacts, the exceeding of thresholds, safety margins, or risks.

LCA Interpretation

It is evident from the results that raw material extraction (A1) is the most impactful stage across all impact categories in
the life cycle of a Curtain Wall.

Amongst raw materials, insulating-laminated glass and aluminum trim drive the raw material impacts across all impact
categories. This is because these materials together constitute 95% of the total raw materials by weight that go into the
manufacturing of Curtain Wall products.

Curtain Wall According to ISO 14025 & EN 15804
Self-Supporting Façade Elements

Though their contribution is much less compared to raw material extraction (A1), manufacturing (A3) and finished
product shipping (A4) also have some contribution to the overall life cycle impacts process.

Since the cut-off methodology was used for this LCA, the end-of-life impacts (C4) are positive for this product and
recycling offsets were not considered for recyclable materials.
