Effortlessly find and compare environmentally friendly materials for your construction projects.

Materials Compass is a powerful tool designed to help architects, engineers, construction managers, and sustainability consultants make informed decisions about building materials. Materials Compass leverages the world's largest LCA database as part of One Click LCA's commitment to supporting the construction industry in achieving sustainability goals. It empowers you to easily evaluate and compare the environmental impact of different materials, leading to more sustainable choices for your projects.
​
​Additional product data is now available
​
Materials Compass has expanded its product data to include valuable information from trusted third-party sources like BASTA in Sweden. This enhancement introduces new data types, such as Standard IDs (e.g., GTIN) for unique product identification, descriptive metadata to aid in informed selection, and health data to help assess material safety. These additions streamline the process of finding, comparing, and selecting the right products for your projects.

These professionals will find the tool invaluable for integrating sustainability into their projects through informed material choices.

Log in to One Click LCA: Access Materials Compass directly from your One Click LCA homepage.

Search for materials: Enter keywords, browse material categories, or filter results by manufacturer. Search results can be further refined using available filters to help you quickly identify the most relevant materials for your project.

Materials Compass provides a range of filters to help you narrow down datasets and find materials that best match your project requirements. Multiple filters can be applied simultaneously and adjusted as needed.

Use the 2-level classification filter to browse materials by material group and sub-group. Examples include:

Filter datasets based on how frequently they are used by other One Click LCA users to help you identify commonly used datasets when multiple options are available:

Use location-based filters to find datasets relevant to your project location:

Use the search for manufacturers filter to limit results to specific manufacturers. Manufacturers can be browsed alphabetically (A–Z) or selected from the full list.

Filter datasets based on the applicable standard, such as:

Narrow results by the dataset publication or expiration year. This helps ensure the use of valid and up-to-date datasets.

Filter datasets by the declared unit:

Limit results by dataset type:

Filter datasets based on available impact indicators, such as colored CO₂ clouds.

Use the search for EPD programs filter to select datasets issued under specific EPD programs.

Refine results using the available data quality ranges from the list.

You can display the results under organized lists or browse directly for local materials using the map view feature, as shown below:

Applying filters will help to narrow down returned options and clicking on any icon will show the related resource on the left-hand side:

You can also choose the GWP standard and unit to match your needs:

Once you've found a material, you can click on it to read its full details, including manufacturer details, environmental impacts, product characteristics, and sustainability data background information:

If you want to dive even deeper, either click on the product image or navigate to 'Actions' and 'View EPD' to open the full source data:

You can even add the resource directly to an ongoing LCA project in One Click LCA, provided it matches the LCA calculation tool data requirements.
and compare options side-by-side.

To compare materials, select the datasets (up to 5) via the 'Actions' button:

Once on the compare screen, you will be able to compare the Global Warming Potential of the selected products reported by its functional unit.

You can bookmark selected materials to help find them easily in the future by clicking the bookmark icon while browsing the materials or search results:

Or while reading more about a resource, select the 'Save as bookmark' option under 'Actions':

To find your bookmarked materials, click the 'My bookmarks' option:

Creating custom lists allows you to save different groups of listed materials and share them with other One Click LCA users. These could be related to a particular project, construction or other use case that you have. To create a new list, navigate to 'My lists' and click 'Create new list':

Give your list a name, description and click 'Create'

You can now add materials to your list by selecting them, clicking 'Actions' and 'Add to list', and selecting the particular list you want to add it to.

Lists can be shared with your colleagues from the List's page by clicking the 'Users' option adding the email address of the user, and clicking 'Invite'.

The Materials Compass is updated weekly alongside the full One Click LCA database, giving users access to hundreds of thousands of EPDs- and growing.

If a specific product EPD isn’t available yet, you can request it to be added to the One Click LCA database.

To add a new product, select the 'Add products option':

You'll be asked to include a message and attach the product's sustainability documentation e.g. EPD, CFP, TM65 etc. Please search for the product first with its EPD number or full name in case it is already included.

We'll let you know once we've reviewed your request and if the data meets our quality standards and isn't in the database already, we'll let you know once we've included it.
