The effects of air tightness, air leakage distributions, and outdoor environmental conditions on air pressure conditions and energy consumption in a high-rise residential building …

What are stacked energy storage systems?

In stacked energy storage systems, they are generally divided into low-voltage stacking and high-voltage stacking. Although both are stacked energy storage, what are the differences? Let’s analyze them from the following points:

How does a stack effect affect a high-rise building?

In a modern high-rise building with a well-sealed envelope, the stack effect can create significant pressure differences that must be taken into account in building design. To improve the performance of ventilation, the airtightness of the building envelope and the apartment and elevator doors should be analysed simultaneously.

What happens if a building has a stack effect?

The stack effect could provoke a number of problems as follows : increase the heating and cooling energy consumption, noise and draft through gaps of doors, pollutions spreading inside of building and incorrect airflows.

Does stack ventilation improve efficiency and effectiveness of four-story building designs?

The objective of optimization is to enhance the efficiency and effectiveness of four-story building designs. One of the significant contributions of this study to the current body of knowledge is integrating stack ventilation (vertical ventilation) with roof channels (horizontal ventilation).

How can solar energy improve Stack ventilation?

Two methods of using stack ventilation are chimneys and atriums, which are often used to produce driving force buoyancy to access enough flows. That's why they use solar energy in several methods to improve the function of stack ventilation .

What is the stack height in a two story building?

The stack height is assumed to be 2 m from the roof in two story building, and other changes are similar to those in the one-story model. The applied changes are increasing the inlet flow and changing the stack material to aluminum (see Table 8). Table 8. The airflow in vents before and after the changes (l/s).
