One Click LCA Planetary

Why launch One Click LCA Planetary?
At One Click LCA, we have promoted low carbon design for over a decade with software, policy development and training. The market has fundamentally changed in this time. We’ve always been about achieving maximum impact for our work. Investment in automation has allowed us to reduce the cost of building LCAs during that time by ten-fold. We’ve also started a program to reduce the cost of delivering EPDs tenfold in the next few years.

We believe now it’s time to change the gear. Embodied carbon efficiency must become the standard, and the market is more ready for this. According to our analysis, we need to have significant improvement on 10 000 major projects each month to have an impact at a planetary level.

How is One Click LCA Planetary different from other existing solutions?
The fundamental differences between One Click LCA Planetary and other tools are the following:

  • It is a planetary solution: available everywhere, in nine languages, with a global database. This makes it suitable for example for global investors or other global organisations.
  • It provides both materials efficiency and embodied carbon metrics at once, not just carbon.
  • It provides global generic (average) impact database as well as global EPD database. All data in the software has undergone a rigorous verification and qualification process.
  • It allows requesting manufacturers to Send Me Data for more EPDs. Manufacturers can use One Click LCA för-verifierad Generatorn to create the EPDs time- and cost-efficiently.
  • It provides a library of assemblies for modelling complex structures easily.

In addition, it is built on One Click LCA, the worlds #1 building LCA platform, which allows users who need more capabilities to easily extend the solutions at their disposal.

Why is embodied carbon important?
Population growth in cities requires unprecedented amount of construction – until 2040, we are building the equivalent of New York City each and every month. Manufacturing the construction materials required for this is highly energy and carbon intensive – in fact, key construction materials, including those covered by One Click LCA Planetary, account for one half of the carbon emissions from new buildings until 2030, and 11 % of the total global carbon emissions.
Is anyone regulating embodied carbon? Should it not be handled by regulations?
Yes, and yes. More and more jurisdictions are enforcing embodied carbon limits on construction – read more about it in this article: The unregulated energy use and carbon emissions from buildings – and how that is changing.

Embodied carbon, as other greenhouse gas emissions, are in addition of private interests, clearly a case for public interest. Policy examples for national regulators and standard-setters have been discussed in Embodied Carbon Review and policies for cities are coming out soon in City Policy Framework for Dramatically Reducing Embodied Carbon.

What is the business benefit of embodied carbon reduction?
Buildings with lower embodied carbon emissions are associated with higher materials efficiency and more energy efficiently manufactured products. Considering materials carbon efficiency as a core target of the design and construction process helps uncover cost and carbon reductions.

Embodied carbon transparency and reductions are also valued by investors, tenants and regulators. Being able to guide a project from embodied carbon point of view may make you stand out and gain a client’s trust, and secure future business with them.

What is the business benefit of combining materials efficiency and embodied carbon?
Building the equivalent of one New York City each and every month consumes a tremendous amount of natural resources. Less materials we use, the less embodied carbon will be emitted.

Highly materials inefficient building can also never be carbon efficient. In our view, a building needs to be designed and delivered in a material-efficient manner first, before moving to choose suppliers. This is why One Click LCA Planetary combines materials efficiency and embodied carbon.

What can One Click LCA Planetary be used for?
One Click LCA Planetary allows you to benchmark cradle-to-gate embodied carbon impacts and materials efficiency of different design options, different materials, manufacturers and products. You can compare differences between concrete, steel and wood structures, or simply differences in structural design options using same material, or differences in product EPDs.

One Click LCA Planetary can be used to power embodied carbon and materials efficiency policies as well as individual design, construction and procurement decisions.

What data does One Click LCA Planetary include?
One Click LCA Planetary covers the ten most carbon-intensive and significant materials categories in construction. These are cement, ready-mix concrete, precast concrete, steel, aluminium, gypsum, bricks, insulation, glass and wood. In addition, the software includes selected essential assemblies.

One Click LCA Planetary includes global generic (average) data, as well as manufacturer specific, third-party verified EPDs. New EPDs are constantly being added, and you can request manufacturers to develop them for inclusion also with One Click LCA Pre-Verified EPD Generator. All data in the software undergoes One Click LCA’s rigorous data verification and qualification process that guarantees consistency and robust assessments.

One Click LCA Planetary does not include databases that are licensed for a fee. Those are available only in the paid versions of the software.

What about all the other construction materials categories?
The free One Click LCA Planetary provides the ten construction materials categories that have the highest carbon and materials use impact. All existing construction material categories, including specialty products, civil works products, building technology, building chemicals, finishing products and furniture are available in paid One Click LCA versions.
Does One Click LCA Planetary have a BIM integration?
The free One Click LCA Planetary does not provide BIM integrations. Those are available in paid One Click LCA Business and higher packages. See commercial plans.
Can One Click LCA Planetary be used to calculate new EPDs?
One Click LCA Planetary in itself does not calculate EPDs, but it connects to the upcoming One Click LCA för-verifierad Generatorn, which allows calculating and publishing third party verified EPDs time- and cost-efficiently for key manufacturing sectors.
How is One Click LCA Planetary different from paid versions of One Click LCA?
One Click LCA commercial versions remain the most advanced building LCA software on the market, and we have a multi-million-euro investment program to expand this leadership. The commercial versions continue to be the only ones supporting regulatory or certification compliance, working with ancillary building materials, such as building systems, BIM integration or advanced ecodesign. One Click LCA add-on modules such as Carbon Designer are reserved for commercial users as well.
