WHAT DOES IT MEAN
Planning of urban buildings in a manner so as to reduce energy consumption and emission of green house gases in general.
METHODS TO BE DISCUSSED
Zero energy building
Urban building energy planning with space distribution and time dynamic simulation.
LOAD INDEX AND TIME DYNAMIC CHARACTERISTICS
This can be explained by the help of following case analysis. In this part, the building heating and air conditioning planning of Beijing city in 2010 is simulated and analyzed to demonstrate the application of this tool by making use of alternative energy sources that is gas in this case. In order to simulate the alternative energy system, it is supposed that the load indices, energy loss, and efficiency are the same in 2001 and 2010. The structure’s central heating source is shown in figure.
SIMULATION RESULTS
Through this tool, we can get the data of energy consumption and environment emission at each node of connecting lines of the energy flow. Here, the gas consumption refers only to the quantity consumed by energy conversion equipment in a heating and air conditioning system. The electricity consumption and power generation amount to the quantity consumed and generated only by energy conversion equipment and electricity demand in heating and air conditioning systems, such as the heating network circulatory power consumption. Some of the simulation results are analyzed below.
CONCLUSION
Although the energy source structure and performance of the energy system are different between China and other countries, the planning method, and this simulation tool, can be also applied to the energy system in other cities.
It is suggested to conduct an innovative UBEP with space distribution and time dynamic simulation in urban planning systems of other countries .
