ERSOS, a small start-up company, was faced with the challenge of designing a unique Air Source Heat Pump to meet the demands of the social housing sector whilst assisting the UK’s sustainability goals of net-zero carbon emissions by 2050. However, due to the limited number of employees at ERSOS and conducting research manually with limited resources, ERSOS could not guarantee the product was cost efficient whilst maximised for sustainability.

Through the use of Makersite’s globally recognised LCA datasets, employing tried-and-tested industry-standard manufacturing methods and cost data, ERSOS was able to exceed its sustainability goals without compromising product price. This was aided through automated tools built-in to the Makersite software allowing for swift and seamless results for ERSOS.

ERSOS ASHP - Internal Layout

An initial BOM for the ERSOS product was uploaded to Makersite. An overall product model with sustainability, cost, and compliance information was available after an automatic matching stage for each component to a material or product group.

A Multi-Criteria Decision Analysis tool (MCDA) used datasets on different injection moulded plastics and refrigerants, enabling Makersite to autocollect the data and rank them based on environment, toxicity, cost, and chemical risk. The user-friendly ranking system allowed the importance rating of each sector to match the priorities of ERSOS. The optimal choice for plastic and refrigerant in terms of sustainability could then be observed. The new data from Makersite was integrated into ERSOS’s decision matrices to evaluate whether different plastics or refrigerants should be chosen. Component changes were shown on the Makersite component Sankey diagram, where the possible Global Warming Potential (GWP) reduction was visible.

The should costing tool on Makersite was able to provide the material and manufacturing cost data through the assignment of product categories and suppliers for each component.

“Makersite’s automated data harvesting allowed for optimisation of our products sustainability and cost in a rapid manor unachievable by conventional methods. This provided the required cradle-to-gate data our company needed, allowing us to fill an emerging market gap before the competition.”

Fast and accurate results to unlock deeper analysis

Beyond 8x time efficiency

By offering extensive data libraries such as Ecoinvent, rapid access of required data reducedresearch times considerably. What took ERSOS 4 full working days between a team of six, was completed in half a day by two people using Makersite.

19,32% CO₂ reduction

By making just a few material and manufacturer substitutions using the Makersite software, the results stacked up to almost a 20% CO₂ reduction. These simple changes mean ERSOS exceeded their sustainability goal and strengthened their customer relationships.  

$671 per unit cost reduction

Makersite reduced ERSOS’s should costing allowing for larger profit margins and a reduced retail price -allowing ERSOS to have improved market control over their competitors.
