Certification demand leads to sustainable product

ASSA ABLOY responded to customer demand for Environmental Product Declarations by using SolidWorks Sustainability software to generate environmental Life Cycle Assessment information on a door-locking mechanism.


Customers are increasingly requesting Environmental Product Declarations (EPDs) for ASSA ABLOY’s products. They need this information to attain environmental certifications for green buildings.


The first step in calculating an EPD is to conduct baseline sustainable engineering on an existing product. ASSA ABLOY’s engineering team in the Netherlands undertook a pilot project to redesign a door-locking mechanism. The team needed an engineering tool to assess and compare the environmental impacts of existing and modified designs. They chose SolidWorks Sustainability software.

Using SolidWorks Sustainability environmental impact assessment and design analysis software, ASSA ABLOY engineers redesigned the door-locking mechanism.


ASSA ABLOY made the door-locking mechanism design more sustainable and reduced material costs.

The team not only lessened the product’s environmental impact, they also reduced manufacturing costs by 15 percent. They cut the number of materials used, replaced custom nickel- and chrome-plated materials with stainless steel, and redesigned the latch tail. SolidWorks Simulation analysis indicated that the design was overly strong, so they also reduced material weight and thickness.
ASSA ABLOY now plans to incorporate SolidWorks Sustainability for new product development as well as modification of existing products.
It is also working with sustainability software and consulting company PE International to develop a web-based EPD generator that builds on SolidWorks Sustainability’s environmental assessments.
