Imagine yourself as having darkness all the time. There are Product Design Engineering (PDE) Perspectives in designing Lighting and Day Lighting. In particular in designing energy efficient building, combining PDE discipline with Industrial Engineering through Ergonomy, known as Human Integrated System.

Getting smart about lighting is an important step to designing energy efficient buildings. Learn how to use day lighting, efficient lights, and good controls to both reduce energy demands and make people happier and more productive.

The sun is predictable and daylight can be a very reliable source of light. Sunlight, views, and daylight are different though, and need to be carefully managed.

Day lighting, or using sunlight to illuminate your building, is an effective way to both decrease your building’s energy use and make the interior environment more comfortable for people.

In commercial buildings, electric lighting accounts for 35 - 50% of total electrical energy consumption. Strategic use of daylight can reduce this energy demand. Daylight also improves people's comfort and productivity.
