Frequently Asked Questions

What’s included in the free trial?
The 14-day free trial only includes our One Click LCA for Building. See the full feature list above to find out what’s included. Note, it is only our building LCA tool which is offered as a free trial. Our product and portfolio tools and our range of add-on features – such as Building Circularity Assessment, Carbon Designer, Life Cycle Costing – are not included in the trial, but you can request a demo of these tools. 
Can I get a free trial if I am a student?
As a student, you can request a free student license instead.
Can I get a free demonstration?
Yes, you can request a demo here.
Which life cycle stages does One Click LCA support?
One Click LCA supports calculations of all life cycle stages from Cradle to Grave as defined in EN 15978, including construction products and process in A1-A5, building use, maintenance, energy and water consumption in B1-B7, end-of-life impacts in C1-C4 and external impacts in module D. However, in most of our tools that are targeted for whole building LCA for different certifications and calculation schemes, the life cycle stages available are restricted to match the requirement of the scheme in question.
Who usually uses the software?
One Click LCA is used in more than 70 countries by green building professionals, including architects, builders, designers, structural engineers, environmental consultants, CSR specialists, and quantity surveyors, as well as construction product manufacturers and investors, governments and institutions.
Can One Click LCA help me attain certification credits?
One Click LCA can be used for and complies with BREEAM, LEED, DGNB, HQE and + 40 other certification schemes, standards and requirements.
Does One Click LCA integrate with other design tools?
One Click LCA integrates with Building Information Models in IFC2x3, IFC4, Revit, ArchiCAD and Tekla Structures formats. It integrates with all energy modeling software supporting gbXML format (including DesignBuilder and IES-VE). It also integrates with Microsoft Excel and other data formats. There is also a direct integration into IES-VE software. Read more here
Which databases are included in One Click LCA and which standards do they follow?
Find the list of current databases here. The system also contains EPD data that is not published under any of the above-mentioned databases. EPDs entered in One Click LCA database include detailed technical descriptions about building products and comply with EN15804 and/or ISO 14025 standards. All EU databases included comply with the EN 15804 standard and North-American databases comply with the ISO 14040/44 standard. For several European and world building material producers, One Click LCA has available manufacturer specific data, which allows for highly precise calculation results. For those who do not yet know which specific building product (manufacturer specific EPDs) they will use, One Click LCA has also country-specific average data (e.g. Ökobaudat and INIES). If One Click LCA is used in areas where there is not yet a comprehensive local building LCA database available, we have a local compensation methodology that allows us to localize the data to get results that match the local manufacturing conditions for a specific area.
