Abstract

Lightsolve is an innovative tool that offers architects and lighting engineers a goal-based simulation platform for daylighting performance evaluation in early stages of building design. Users can import their own 3D model and define their own design goals for a comprehensive spectrum of daylighting performance perspectives regarding task illumination, visual comfort, overheating risks, health effects and visual interest of a space. The tool provides key information to the designer that is easy and intuitive to grasp thanks to a combination of unique, visual and interactive graphical display formats. Available visualization options include photo-realistic renderings, full-year temporal performance representation as color maps, and spatial performance distribution through false-color renderings. Both model orientation and localization can be user-defined, and weather data (e.g. TMY) can be used to get climate-specific results. Accuracy is ensured by the usage of the ubiquitous and extensively validated Radiance simulation tool.

Lighting

Lighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings.

User interface design

User interface (UI) design or user interface engineering is the design of user interfaces for machines and software, such as computers, home appliances, mobile devices, and other electronic devices, with the focus on maximizing usability and the user experience. In computer or software design, user interface (UI) design primarily focuses on information architecture. It is the process of building interfaces that clearly communicates to the user what's important. UI design refers to graphical user interfaces and other forms of interface design.

Daylighting

Daylighting is the practice of placing windows, skylights, other openings, and reflective surfaces so that direct or indirect sunlight can provide effective internal lighting. Particular attention is given to daylighting while designing a building when the aim is to maximize visual comfort or to reduce energy use. Energy savings can be achieved from the reduced use of artificial (electric) lighting or from passive solar heating.
