BACnet BACnet®, short for “Building Automation Control Network”, is a data communication protocol for building automation and control networks. BACnet is both an international (ISO) and ANSI standard for interoperability between cooperating building automation devices. Originally developed in 1987 under the auspices of the American Society of Heating Refrigerating and Airconditioning Engineers (ASHRAE), BACnet has been an ANSI standard since 1995 and an ISO standard since 2003. BACnet is a registered trademark of ASHRAE. BACnet is a standard data communication protocol that enables interoperability between different building systems and devices in building automation and control applications. BACnet offers a flexible range of networking options including the use of Ethernet or IP-centric infrastructure and a simple, low cost twisted pair communication called MS/TP that is based on EIA- 485. A sophisticated routing capability allows scaling of BACnet internetworks into larg...

Lighting design is an Art as well as a Science . As a science,the amount of illumination required and certain aspects of the quality of light have been quantified.  As an art  light is an experience of senses,it is not an intellectual experience. Lighting should create an atmosphere pleasing to the occupants whether in an office,store,restaurant or home. Lighting should provide visibility ,character,and mood as well as relate harmoniously to the space in which it is used. EFFECT ON ARCHITECTURE Light defines space,reveals texture and color,shows form, indicates scale,separates functions.Lighting is dynamic. EFFECT ON INTERIOR DESIGN Light is invisible until it strikes a surface and  molds our environment. The angle and quality of light ,along with intensity determines how we perceive space,its occupants and its furnishings. There is a vital relationship between Light and color PLANES OF BRIGHTNESS Brightness in space establishes the character or feeling of t...
