6 FAQs about [Wall heat absorption and solar container]

Does wall solar absorption affect annual heating and cooling energy use?

Impact of wall solar absorption on annual heating and cooling energy use Table 2 shows the annual heating and cooling energy uses of the lightweight (LW) and mass timber (MT) buildings with different solar absorption coefficients on walls relative to the absorption coefficient of 0.7.

How does solar energy affect the temperature of a container?

At 07:00 AM, the heat energy from solar radiation begins entering the walls. Heat accumulation slowly begins to increase reaching the maximum penetration at 2:00 PM. The effect of heat absorption, at maximum penetration, causes the inner surface of the container walls to increase the temperature by around 4.3°C.

What are the simulation results of heat accumulation on the container walls?

displays the simulation results of heat accumulation on the container walls. This simulation considers the solar radiation in clear-sky condition, with the constant supply air temperature inside the container at 0°C. At 07:00 AM, the heat energy from solar radiation begins entering the walls.

The largest impact is in the mild climate of Los Angeles, CA, where the heating and cooling energy use can almost double or cut in half depending on the choice of exterior color of the walls. However, we can also see that the impact on the total energy use is much less due to the opposite impacts of solar absorption on heating and cooling. Table 2.

How does solar absorption affect heating and cooling demand?

Reducing the solar absorption coefficient from 0.9 to 0.3 resulted in up to 46% lower cooling demand and a 70% increase in heating demand depending on the climate. Peak demand reductions for heating and cooling energy were similar to the reduction in heating or cooling energy use.
