Overview
h2x Engineering is a design software focused on revolutionising how HVAC systems are designed and calculated. Their platform empowers engineers to automate complex calculations and create precise, compliant designs with greater speed and accuracy.
This case study highlights my role as the sole UX/UI designer at h2x, where I led the design of a new feature aimed at transforming raw data into usable materials within the software. This feature is currently in active development and designed to enhance user efficiency and overall experience.

In the construction industry, there is a diverse range of manufacturers for different materials and components. We aim to ensure our users utilise the specific sets of materials and components suitable for their projects, as they are all currently set to default options. As this is a new envisioned feature, I collaborated with the development team in a meeting to outline project requirements.

With a tight 1-week deadline, we quickly dove into designing the possible features required. I then created high-fidelity wireframes that detailed the user flow and proposed new Marketplace features. Throughout the process, I collaborated closely with the development team to assess feasibility, incorporate feedback, and refine each iteration.

Finalised user flow for uploading data and creating components automatically
To finalise the user flow for uploading data and automatically creating components, I mapped out each step users would take from data submission to design generation. This involved identifying key interaction points, defining system responses, and ensuring a seamless, intuitive experience. The flow was designed to minimise user effort while maximising accuracy and customisation of the generated components.

I had the opportunity to hand over a demo for an upcoming client meeting due to the delay in the actual development for the meeting. I crafted 4 distinct demonstrations, each tailored to a specific user flow and case, showcasing the final outcome.
Note: It's understood that the design in these demos has undergone some updates by the time of the writing of this study.
