Soltactics brings to market a unique, real-time sensing, self-adjusting skylight control system that will minimize energy losses while maximizing available day lighting. The HOSS product is designed for both new construction as well as retrofit. Some of the main HOSS benefits are reduction in costs, improved sales and greater productivity.
Maximizing the amount of natural light reduces energy costs. Recent analysis has shown that sky lighting has enormous potential to provide energy savings in single-story commercial buildings. Turning off electric lights when sufficient daylight is available can save a significant amount of lighting energy costs. Because daylight introduces less heat into a building than the equivalent amount of electric light, cooling costs can also be reduced.
In addition, Daylighting reduces the cost of artificial lighting, which accounts for 40% to 50% of the energy consumption in many commercial buildings. When sufficient daylight is available, a good Daylighting system can significantly reduce artificial lighting requirements and the associated energy costs.
Studies have shown that adding skylights to a store configuration can boost sales by 40%. Around 1995, “big box” retailers began to install skylights over product sales areas. The original objective was to improve the appearance of products by admitting daylight. Natural light has a color rendition index (CRI) of 100%, making products seen in natural light far more attractive and increasing sales.
The U.S. Department of Energy has published extensively detailed statistical studies of the national costs of energy lost through building windows and skylights. A 2004 study states; “Conventional windows are the weak links in the building envelope. Windows currently consume 3.8 quadrillion Btu of energy in the U.S. annually in the form of heating and air conditioning loads, at a cost of more than $30 billion.
