Exergy Consumption: Meaning & Applications to Built Environment

In summary, according to an article in Energy and Buildings 2008 by Shukuya Masanori, exergy can be defined as the portion of energy that allows for dispersion of energy and matter. When exergy is consumed, it means that it changes from a useful state (such as electricity or unburnt natural gas) into low-grade heat (such as car brake pads or electric motor cooling air).

What does it mean for exergy to be consumed ?. An article in Energy and Buildings 2008 tilted "Exergy concept and its application to the built environment" by Shukuya Masanori, stated that exergy of a system can be defined as that portion of energy which allows for dispersion of energy and matter. So what does it mean then for exergy to be consumed say for example by a cooling HVAC system that's design to keep "cool" exergy (exergy that allows heat from the environment to flow into the system) at a desired level.

Note: When energy or matter is dissipated in the macroscopic environment it eventually changes from one energy form to another.

I would say that energy is consumed when it changes from a useful state, electricity, unburnt natural gas etc. into low grade heat car brake pads, electric motor cooling air et al.
 

Related to Exergy Consumption: Meaning & Applications to Built Environment

1. What is exergy consumption?

Exergy consumption is a measure of the total amount of energy that is used in a system to perform useful work. It takes into account both the quantity and quality of energy, and is often used to evaluate the efficiency of energy conversion processes.

2. How is exergy consumption different from energy consumption?

While energy consumption measures the total amount of energy used in a system, exergy consumption takes into account the quality of energy. This means that exergy consumption can provide a more accurate assessment of the efficiency of energy use in a system.

3. What is the importance of exergy consumption in the built environment?

In the built environment, exergy consumption is important because it can help identify areas where energy efficiency can be improved. By analyzing the exergy consumption of buildings and systems, we can find ways to reduce energy waste and increase overall efficiency.

4. What are some applications of exergy consumption in the built environment?

Exergy consumption can be used in the design and evaluation of energy systems in buildings, such as heating, ventilation, and air conditioning systems. It can also be used to assess the efficiency of energy sources, such as solar panels or geothermal systems, in a building.

5. How can exergy consumption be reduced in the built environment?

Exergy consumption can be reduced in the built environment by implementing energy-efficient design strategies, using renewable energy sources, and improving the insulation and building envelope of a structure. Regular maintenance and optimization of energy systems can also help reduce exergy consumption.
