Smart buildings

Buildings consume an extraordinary amount of energy . Commercial, industrial, or residential expend their energy in different categories, but numerous studies have shown that energy efficiency and intelligent building technologies reduce energy bills. Not only that, but smart buildings can have a strong multiplier effect in terms of shifting expenditures from utility bills to other investments, including job creation for improved economic security.

But what exactly is a smart building? Is a residential building smart if it has a home energy management system? Is a commercial building smart if it has been retrofitted with energy efficient windows and better insulation? Is it a net-zero building ? meaning a building that is so energy-efficient that its electricity needs can be supplied with onsite renewable generation. The definition of a smart building is more difficult to define than the Smart Grid itself. For the Smart Grid, the simplest definition is the bidirectional flow of information and electricity. But the definition of smart buildings is more complex and complicated. It is complex because buildings have different occupant uses and energy use patterns. It is complicated because building energy use is contingent not only on the amount of intelligence inside the four walls (lighting controls, occupancy sensors, etc.), but on the intelligence of the design, materials, and construction of the four walls too. In other words, its energy efficiency.

Most people would agree that a green building must be an energy efficient building. But not everyone agrees on how to convert an energy efficient building to a PLUS energy building. It is the last step of sustainable architecture. Number of our new patented solutions can help you ensure green conversions.

Thanks to the patented solar augmented reflector systems, the veranda and roof elements can assume a number of functions: it not only provides a part of the power used in the house, but also feeds green electricity into the grid. Additionally, the energy generating roof/wall elements of the PV system regulates the daylight, provides shade and acts as a night screen and protects not only against sun and glare but also heat and noise.

Underground air ventilation increases energy gain by winter/summer heat/cold transfer. Usually space heating and hot water storage tanks serve as a heat sink for reasonable waste heat utilization. Through the summer, the heat demand is much lower but the heat of the electric generation process can be transformed into cooling energy by an absorption chiller. Trigeneration is sometimes referred to as CCHP (combined cooling, heating, and power generation).
