Along with skylights and other lighting technology, saving energy is possible through integrated daylight systems. These systems incorporate dimmable light ballasts, workstation controls, environmental sensors and building management to reduce the need for artificial lighting and rely more on the sun and other natural lighting.
Factors in Lighting Design
When designing integrated daylight systems, there are four main factors to consider. The first one is human needs. Lighting should focus on what we need to do our job, including optimal visibility, health and well-being. These all lead to increased productivity. The next factor is aesthetic needs. Aesthetics enhance the beauty of an environment to make it more attractive. There is also the economic factor. Almost everybody loves to save money, so there is significant cost savings associated with saving energy. Another factor to consider is the environment. Natural lighting reduces carbon emissions and reduces the amount of outdoor light pollution.
Lighting and its Purpose in a Retail Environment
When used in a retail environment, integrated daylight systems has a positive impact on the store overall. Studies show that the increase in natural light resulted in higher sales. In fact, sales increased 31-49%, with the average about 40%. Skylights have an effect on the employees as well. They help increase productivity and boost employee morale. In order to optimize this effect, it’s important to consider sun angles and reduction of sun glare.
Cost Effectiveness
An integrated system in a commercial environment can save 40-80% on energy costs annually. Light level tuning can save up to 25%, while workstation control and fewer fixtures can result in a 35% savings. Daylight harvesting can save 12-17%, variable load shedding can save 15-20% and occupancy control can mean a savings of up to 35%. These numbers depend on the building’s energy rates and the physical layout of the workspaces.
When you need a large selection of skylights and accessories, Wasco Skylights is the place to go. They carry a variety of designs.
