A software company specializing in energy simulation and LCA calculation for buildings, needed to redesign their building component catalogue. The existing catalogue was functional but lacked user-friendliness and efficient navigation features. (for reference see at the bottom of the page)

The main challenge was to create a comprehensive and intuitive interface that would allow users to:

Easily browse and search for components

View detailed information about each component

Edit components as needed

Compare different materials based on performance metrics

Task flow analysis

The redesign focused on several key areas:

Improved Catalogue Overview

Enhanced Search Functionality

Integrated Elasticsearch for high-speed, full-text search capabilities

Implemented an overlay search interface to reduce cognitive load

Added category-based search results with highlighted keywords.

Comprehensive Filtering System

Designed a full-screen modal for filters to avoid overwhelming users

Included multi-select autocomplete fields for material filtering

Clear Search Results

Results are displayed per categories similarly to the Catalogue overview tabs and the word or words typed by the user are highlighted.

This approach facilitates the findability of the information and offer consistency with the main overview

Detailed Component View

Created a layout that prioritizes key information (name, category, description)

Implemented modular components for technical specifications, environmental impact data, and material layers

Added white space for potential future features or related information

The redesigned catalogue significantly improved user experience by:

Reducing the time needed to find specific components

Providing clearer and more accessible information about each component

Offering more powerful search and filter capabilities

Creating a consistent and scalable design language across the platform

Here is the original version of catalogue overview page. The initial UI Audit highlighted some issues

Information Density: The table is very dense with information, making it difficult to scan and read. There is a lot of text in each cell, and the columns are not very wide.

Color Contrast: The text color in the table is quite light, and the background color is white. This can make it difficult to read the text, especially for people with visual impairments.

Language: The interface appears to be in German. If the target audience is international, it would be beneficial to include an option to switch the language to English.

Search bar: The search bar is placed directly above the table data, and may not be immediately noticeable to users.

Pagination: The pagination information is displayed at the bottom of the table ("1-7 of 7 items").
