Introduction
Low energy roofing system (transfer lightweight) comprises of a structural element where it
concerns roofing homes with roofs that are low in energy absorption hence making the house
less hot. Houses in hot areas make it uncomfortable for individuals to live inside. Several
individuals tend to require homes and other buildings that are subjected to cold roofing
strategy (Baniassadi et al., 2018). A cool roof is that having designed with capabilities of
reflecting more sunlight and engross less heat than a standard roof. Cool roofs are made of a
vastly reflective type of dye, a sheet casing, or greatly reflective tiles or grits. Nearly any sort
of building can gain assistance from a cool roof, but also the consideration of the area climate
and other issues before deciding installation of cool roofs. However, in severe cold
environments, roofs aspect two important encounters; absorbent of heat appropriately, and
controlling dampness trying to discharge from the living space. The colder the weather and
the longer the wintertime, the more noticeable freezing issues can become. Deficits and poor
building performs that are overlooked in an added forgiving climate convert very obvious in
some places. A simple understanding of one’s roof system and the contests faced can assist in
identifying the problem sources.

Skylight Roofing System (SRS)
Gombarick and others (2018) suggested that system (roof skylight) is the maximum sensitive
part of the general building envelope that intercedes transparent and opaque qualities of a
building structure. Transparent basics represent around ninety percent level and are amongst
the most advanced rudiments influencing both daylighting eminence and thermal conditions;
while opaque modules, such as mullion and sash assemblages, constitute nearly 10%.
Irrespective of one’s location, these qualities will be under the influence of solar radioactivity
that influences behavior that maximizes or minimalize interior load. Therefore, the features of
