Photovoltaic gypsum board

Do commercial buildings need a photovoltaic system?

If commercial buildings in the U.S. with roofs over 5,000 square-feet were to install photovoltaic (PV), or solar, arrays, they could potentially provide enough energy to power nearly 60 percent of the total commercial electricity demand. Therefore, having a PV system is not a necessity but could significantly contribute to powering commercial buildings.

Does gypsum board reduce temperature?

For example, Sari et al. examined the thermal response of gypsum board with eutectic mixture of capric acid and stearic acid in a laboratory scale test room, and reported that thepeak indoor temperature was reduced by 1.3 °C. In another study, a reduction of 3.1 °C in the peak indoor temperature was reported by Karaipekli et al. .

Can gypsum board ceiling reduce cooling load?

This study investigated the thermal/energy performance of gypsum board ceiling incorporating a composite form-stable phase change material (FSPCM) for cooling load reduction in summer periods. The FSPCM was prepared by directly impregnating 51.3 wt% methyl stearate into porous diatomite.

How does a tightly packed rooftop PV array work?

A tightly packed rooftop PV array, as shown in Figure 7, does not provide enough space to maintain the panels or the roof. Providing additional space between the arrays and the roof membrane increases ventilation and reduces heat build-up, resulting in more efficient panels.

Can gypsum wallboard be used for cold storage?

Numerical and experimental research of cold storage for a novel expanded perlite-based shape-stabilized phase change material wallboard used in building Capric acid and stearic acid mixture impregnated with gypsum wallboard for low-temperature latent heat thermal energy storage
