This system is based on microprocessor 8085 CPU. This system is capable of continuously moving messages, which is fed through a computer keyboard. This is a high utility item specially for displaying multiple advertisements through a keyboard.
,According to the International Energy Agency, comprising of 22 countries on average, one third of operating energy usage in the developed world goes for heating,. Cooling, lighting and the operation of appliances in non-industrial buildings such as homes, hospital offices and schools. These estimates do not take into account the amount of embodied energy in building products and its impact on the environment.
Operating energy efficiency in residential and commercial building is greatly enhanced in highly insulated and air tight building envelope systems, Increased insulation on foundations, walls, and attics and insulated doors and windows reduces the operating energy is buildings. However the need for insulating products contributes to higher embodied effects.
Tokyo national Conference Boar Wood is a good and natural insulator. Due to its cellular structure, wood traps air resulting in low conductivity and good insulating properties. Steel conducts heat 400 times faster than wood. High conductivity causes thermal bridging leading to increased energy use for heating and cooling. So there is a need for additional insulations.
