Dry air is a relatively good electrical insulator, so if something is charged the charge tends to stay.

Capacitance, property of an electric conductor, or set of conductors, that is measured by the amount of separated electric charge that can be stored on it per unit change in electrical potential. Capacitance also implies an associated storage of electrical energy.
The new low solar gain low-e coating blocks some of the solar radiation incident on it, by reflection, and is quite effective in hot climates like florida's. There are various trade names for this hot climate insulated glass. The common feature is a solar heat gain coefficient (shgc) lower than the visible transmittance (vt).
Even though the walls and ceilings of both are insulated, they still aren’t comfortable when the temperatures get extreme.
If a spark is created, electrons move off one object and onto another. During the spark, energy is also released in the form of light, heat and sound. The buildup of excess charge on an insulated body and the resulting spark (or electric discharge) caused by this buildup, are both properties of static electricity.
The interaction between static electric charges is called electrostatics. This charging if electrons protons gaining electrons, negative charge.

As with magnetism, like charges repel and unlike charges attract. Charge does not build up on metalic rods when they are rubbed. The charge can escape through the body to earth, hence metals are known as conductors. Materials such as ebonite and silica do not allow charge to low in this way and are called insulators. For insulators to be effective they must be kept dry and the air around them must also have a low humidity.

Capacitor, device for storing electrical energy, consisting of two conductors in close proximity and insulated from each other. Capacitors have many important applications and are used in digital circuits and as filters that prevent damage to sensitive components and circuits caused by electric surges.
Capacitors store electrical energy on their plates in the form of an electrical charge. Capacitors consist of two parallel conductive plates (usually a metal) which are prevented from touching each other (separated) by an insulating material called the “dielectric”. When a voltage is applied to these plates an electrical current flows charging up one plate with a positive charge with respect to the supply voltage and the other plate with an equal and opposite negative charge.
