Carbon-conscious site selection

One Click LCA Site Designer makes it possible to make carbon-aware decisions at the earliest phase of your project – even before any design work has started.

Optimise carbon impacts at site planning stage

One Click LCA Site Designer makes it possible to calculate and compare the carbon impacts of different sites, energy supplies and transport scenarios. Enabling you to make carbon-informed choices at the earliest stage of your project.

One Click LCA Site Designer enables you to create an outline carbon figure for each potential project location by assessing factors from geotechnical conditions and land use change to operational transport impacts, based on ready-made scenarios. The results can be used to support feasibility analysis, as well as carbon-aware site selection.

With Site Designer you can easily calculate impacts from materials and energy, based on a wide range of benchmarks for different building types and energy mix scenarios. You can also compare different scenarios for how to heat, cool or light your buildings, and start working earlier – and more effectively – on carbon optimisation.

Frequently Asked Questions

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.

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.
