Modular buildings may likewise contribute to LEED requirements in any kind site-built structure may, and can even supply an advantage in the fields of Sustainable websites, Energy and Atmosphere, Materials and Resources, and Indoor Environmental Quality. Modular construction can also give an advantage in similar categories from the International Green Construction Code.
Ability to support remote locations. Especially in countries where potential markets may be found far from industrial facilities, such as Australia, there may be much higher prices to build a in-house property in a distant area or a place experiencing a construction boom such as mining cities. Modular buildings can also be beneficial in providing medical and sanitary facilities where time, space, and money are an issue.
Improved Air Quality - Many of the indoor air quality issues identified in new construction result from high moisture levels in the farming materials. Since the modular construction is substantially finished in a factory-controlled setting using abrasive materials, the prospect of elevated levels of moisture being trapped inside the new construction is removed.
Quality. Combining traditional building techniques, quality manufacturing and third-party agencies that offer arbitrary inspections, testing, and certification solutions for quality control, commercial modular structures are built in strict accordance with appropriate local, state, and federal rules and regulations. Due to the requirement to transport modules to the final site, each module has to be built to independently withstand traveling and setup prerequisites. Thus the closing module-to-module assembly of independently durable elements can yield a last product that is stronger than site-built constructions. Modular buildings often utilize Structural Insulated Panels (SIPs) in construction, which offer a range of advantages over traditional construction materials. SIPs panels are a mild yet durable mix of panel board and either closed-cell polyurethane (PU) or expanded polystyrene (EPS) insulating foam. They also offer superior damp and cold resistance when compared to wood and other materials, and are immune to both compression decreasing and cold bridging.  Modular units might also be made to match in with outside aesthetics of any existing construction and modular units after constructed can be almost indistinguishable from a site-built construction.
Modular buildings are argued to have benefits over conventional buildings, for many different factors.
Environmentally friendly building procedure. The controlled environment of the mill allows for more accurate construction while allowing the additional stuff to be recycled in house. 
Indoor construction. Assembly is different from weather, which can increase work efficiency and avoids damaged building material.
Modular construction allows for the building and the site work to be completed simultaneously. According to some substances, this can decrease the total completion schedule by up to 50%. This also reduces labour, financing and oversight expenses. To save even more time and money, the majority of design and engineering areas are part of the manufacturing procedure. During site-built construction, walls can't be placed until flooring are in position, and ceilings and rafters cannot be added till walls have been erected. On the other hand, with modular construction, walls, floors, ceilings, and rafters are all built at the same time, then brought together in the exact same mill to form a construction. This procedure can enable modular building times of half that of traditional, stick-built structure.
Low waste. With the same programs being constantly built, the producer has records of precisely what amount of substances are necessary for a specified job. Together with the consistency, most builders can design systems that use common lengths of timber, wallboard, etc., cut things with maximum efficiency, or be able to order special spans in bulk. While squander from a site-built dwelling may typically fill several large dumpsters, construction of a modular house creates much less waste. As stated by the UK group WRAP, up to a 90% reduction in substances can be achieved through using modular structure. Materials minimized include: timber pallets, shrink wrap, cardboard, plasterboard, wood, bricks, concrete, and cement.
Flexibility. One can continually add to a modular construction, including producing high rises. When the needs change, modular buildings may be disassembled and the modules relocated or refurbished to their next usage reducing the requirement for raw materials and minimizing the total amount of energy expended to make a building to meet the new demand. In essence, the entire building could be recycled in some cases.
