Improved Air Quality - A lot of the indoor air quality issues identified in new structure result from high humidity levels from the farming materials. Because the modular construction is substantially finished in a factory-controlled setting using abrasive materials, the prospect of elevated levels of moisture being trapped in the new construction is eliminated.
Modular buildings can likewise contribute to LEED requirements in any kind site-built construction can, and may even provide an advantage in the areas of Sustainable websites, Energy and Atmosphere, Materials and Resources, and Indoor Environmental Quality. Modular construction may also give an advantage in similar classes in the International Green Construction Code.
Indoor construction. Assembly is independent of weather, which may boost work efficiency and avoids damaged construction material.
Modular buildings have been argued to have advantages over conventional buildings, for a variety of reasons.
Low waste. With the very same plans being continuously built, the producer has records of exactly what amount of materials are needed for a given job. With the consistency, builders can design systems which use common lengths of lumber, wallboard, etc.. cut items with maximum efficiency, or have the ability to order special lengths in bulk. While waste from a site-built dwelling may typically fill several big dumpsters, building of a modular dwelling generates much less waste. As stated by the UK group WRAP, up to a 90% decrease in materials can be accomplished via using modular construction. Materials minimized contain: wood pallets, shrink wrap, cardboard, plasterboard, wood, bricks, concrete, and cement.
Environmentally friendly building procedure. The controlled environment of the factory allows for more accurate construction when allowing the extra stuff to be recycled in house. 
Ability to support remote locations. Particularly in countries in which potential markets may be found far from industrial facilities, such as Australia, there can be much higher costs to build a in-house property in a distant area or an area experiencing a building boom such as mining cities. Modular buildings are also beneficial in providing medical and sanitary facilities at which time, space, and money are a problem.
Modular construction permits for the construction and the site work to be completed concurrently. According to some substances, this can reduce the total completion schedule by as much as 50%. This also reduces labour, financing and supervision expenses. To save time and money, the majority of design and engineering areas are part of the manufacturing process. During site-built construction, walls cannot be set until floors are set up, and ceilings and rafters can't be added until walls are erected. On the other hand, with modular structure, walls, flooring, ceilings, and rafters are all built at precisely the exact same time, then brought together at precisely the exact same mill to form a building. This process can allow modular construction times of half an traditional, stick-built construction.
Quality. Combining traditional building methods, quality manufacturing and third-party agencies that provide random inspections, testing, and certification services for quality control, commercial modular buildings are made in strict compliance with appropriate local, state, and national rules and regulations. On account of the requirement to transport modules to the final website, each module has to be constructed to independently withstand travel and setup prerequisites. Thus the final module-to-module assembly of independently durable components can yield a last product which is stronger than site-built structures. They are air-tight, and as such provide excellent thermal performance. They also offer superior moist and cold immunity when compared to wood and other substances, and are resistant to both compression shrinking and cold bridging.  Modular units may also be made to match in with external aesthetics of any existing construction and modular units once assembled can be almost indistinguishable from a site-built structure.
Flexibility. An individual can continually add to your modular construction, including creating high rises. When the demands alter, modular buildings may be disassembled and the modules relocated or refurbished for their next use reducing the demand for raw materials and minimizing the total amount of energy expended to make a construction to fit the new demand. Essentially, the whole construction could be recycled in some instances.
