Optimise early designs instantly. No material quantities needed.
Solve the biggest challenges when it comes to optimizing the carbon performance in early design stages. With Carbon Designer, you can quickly generate and compare different design options by using pre-defined building structures or materials.
Choose a pre-defined typical building that is specific to your country and building type. These typical buildings give you shoebox quantities of materials needed. Adjust the shapes and sizes of the reference building and get instant carbon performance results. This is your baseline design.
Apply a scenario to quickly change the entire structure of the building e.g. to wood, steel or concrete. Or change each building element, such as changing the floor slab to a concrete slab assembly with bubble deck. Or make your own construction assembly.
Compare different design scenarios and see immediate carbon saving results.

Generate baseline buildings per LEED and BREEAM NOR - NS3720 requirements
Carbon Designer can be used to generate baseline buildings for LEED v4 (archetype or alternative design options), create BREEAM NOR 2018 concept stage options, and more.

Use pre-defined structures or create your own assemblies
Carbon Designer enables you to generate early design options quickly with its built-in scenarios, and pre-defined structures. You can also create organization-level private assemblies called private constructions, to customize the tool to your specific needs.
Trusted by governments

Norway, Statsbygg
Statsbygg. the Norwegian Directorate of Public Construction and Property, advises, owns, manages and develops government properties. Statsbygg owns all government properties, including all embassies, and invests some $650 million in construction annually. They use Carbon Designer to define baseline performance and to set a target for at least 30% reduction.

Finland, Finnish Association of Construction Product Industries
Finland has launched its free low carbon design tool, developed based on Carbon Designer. The tool complies with Finnish Ministry of Environment’s whole life carbon assessment of buildings method, which is applied in the upcoming building carbon regulations, and European standards. The tool is developed using the innovative Carbon Designer tool supporting very early design decisions.

Can I use Carbon Designer if I don't have any material quantities?
Absolutely, yes. The only things you need to know are building type, gross floor area, and number of floors. The rest you can either customize or use default values. Carbon Designer will generate shoebox material quantities that would be translated into carbon impacts.
