In India the demand for housing is ever increasing and hence there is an increase in demand for building materials. Providing affordable housing is a challenge for developing country like India. India have an shortage of millions houses. Now days, more than 17 million retired shipping containers are stacked on the port worldwide. Container building still facing the various challenges. To avoid this challenges GFRG panels use as a Walls and Roofs of container house. So, Container house using GFRG panels provide an adequate solutions to the various problems. Building materials which are energy efficient strong and durable at an affordable cost are in great demand GFRG panels are of much relevance in India where there is tremendous need for cost effective mass scale and rapid housing. They are not only eco-friendly, but also resistant to termites, heat, rot, corrosion, water and fire. Concrete infill with vertical reinforcement rods enhances its vertical and lateral load capabilities. Comparative studies of GFRG and conventional buildings have been carried out in the present investigation. Rapid wall panel provides speedier construction and leads to environmental protection. Subsequently, it is a perfect option building material to replace bricks or concrete blocks. GFRG wall is a green product which can erect a building fast in prefabricated method. This paper highlights the positive aspects of GFRG panels with respect to Time, cost of construction Strength, affordability, energy efficiency over the conventional construction materials and its suitability in the Indian Housing Scenario. This research aims in providing adequate shelter for all individuals that is one among the recent challenges long faced by the developing countries. Economical plan and development of structures, utilizing green material is an option in contrast to exhaustion of totals and increment in cost of concrete. Glass fiber reinforced gypsum panel (GFRG) is a green material, which is a rapid wall construction method and a cost effective construction process. With the end goal to enhance the productivity, and decrease of waste, the lean the development has been presented as another administration rule for better execution. In India, the usage of lean administration in the development industry is a noteworthy errand. Because of the absence of consideration and uneducated towards the lean administration guideline the proprietor, contractual worker, engineers and so on are as yet creating a stage to actualize this standard in their task. This venture primarily centers on to recognize the potential outcomes of execution of lean administration in the development industry. This paper shows the probabilities of compelling usage of lean administration guideline in the development industry, which can definitely diminish the use of time, increment the nature of work, and benefit rate by wiping out the wastage of materials. It finally, points in giving lodging to all classes of people, in this way enhancing the economy of India. Going through this study, it will explore & analyze some projects and case studies from many points of views, Geometrically, Architecturally, structurally, financially, and of course environmentally. The deployment of containers as building modules has grown in popularity over the past years due to their inherent strength, modular construction, and relatively low cost. Finally, conclusions are going to be drawn on the important worth of lean construction against the traditional practice with consideration for the future benefits within collaborative technological models.

Cost Of Construction

Embodied energy and cost of construction of any building depends upon the consumption of resources, more specifically construction materials. In housing clusters, the spaces provided for horizontal and vertical circulation of occupants such as corridors and contribute in the built-up area of individual unit without any increase in the usable/carpet area. Thus, an efficient architectural planning of common circulation spaces plays a major role in lowering the built-up-to-carpet area ratio of individual housing unit in clusters. This may, thus, result in lesser embodied energy and maximum area availability for occupant usage. In the present study, 30 clusters of Indian affordable housing units (IAHUs) of similar typology and different architectural designs are analyzed. The built-up and carpet area of each IAHU are estimated, and the ratio of the built-up to carpet area is calculated. Detailed estimates of construction materials for each IAHU is prepared, and cost of construction and embodied energy is calculated. The calculations of embodied energy and construction cost are done for major construction materials, viz., cement, steel, bricks, sand, and coarse aggregate and compared with different built-up-to-carpet area ratio. The study of IAHUs concludes that a variation of 1.30 to 1.62 in the built-up area-to-carpet area ratio results in variation in construction cost (INR 13,425.00 to 20,138.00 per m2 carpet area) and embodied energy (4–6.5 GJ per m2 carpet area). Analysis suggests that the IAHU with a lower built-up-to-carpet area ratio exhibits reduction in the cost of construction and embodied energy simultaneously. Thus, an efficient architectural design plays a major role in improving the sustainability of IAHUs and built-up-to-carpet area ratio is an important indicator of sustainability.

Abstract In the U.S., population aging is coinciding with a growing affordable housing crisis. Evidence suggests that housing security contributes to health, but less is known about how affordable housing affects aging in place. We use a nationally representative sample (n=5,117) of older community-dwelling Medicare beneficiaries from the 2015 National Health and Aging Trends Study to test the association between housing cost burden (HCB) and moving to a nursing home, death, or remaining in the community by 2017. Among 2017 community-stayers (n=4,836), we also test the association between HCB and unmet care need, defined as experiencing a consequence related to 12 mobility (e.g., stayed in bed), self-care (e.g., skipped meals) and household (e.g., no clean laundry) activities. HCB is the proportion of income spent on rent or mortgage: low (<30%), moderate (30-50%), severe (≥50%), or home paid off (referent). Among nursing home movers, 26% had moderate or severe HCB in 2015 compared to 16% of community-stayers. Informed by the person-environment fit perspective, weighted stepwise regression models (multinomial and logistic) adjust for race, age, sex (Model 1), self-rated health, probable dementia (Model 2), living with others and high income (Model 3). Severe HCB is significantly associated with nursing home entry (RRR=2.66, SE=0.89) and this association is only partially mediated by health factors (RRR=2.16, SE=0.72) and resources (RRR=1.95, SE=0.64). Among community-stayers, severe HCB is significantly associated with unmet care need across all models. This study suggests that affordable housing is an important protective factor for older adults to age well in the community.

In the year 2017, about 89% of the total energy consumed in the US was produced using non-renewable energy sources, and about 43% of tenant households were cost burdened. Local governments are in a unique position to facilitate green affordable housing, that could reduce cost burdens, environmental degradation, and environmental injustice. Nonetheless, limited studies have made progress on the costs and benefits of green affordable housing, to guide decision-making, particularly in small communities. This study investigates density bonus options for green affordable housing by analyzing construction costs, transaction prices, and spillover effects of green certifications and affordable housing units. The authors employ pooled cross-sectional construction cost and price data from 422 Low-Income Housing Tax Credit (LIHTC) projects and 11,016 Multiple Listing Service (MLS) transactions in Virginia. Using hedonic regression analyses controlling for mediating factors, the study finds that the new construction of market-rate green certified houses is associated with small upfront costs, but large and statistically significant price premiums. In addition, the construction of market-rate green certified houses has large and statistically significant spillover effects on existing non-certified houses. Existing non-certified affordable housing units show small and often insignificant negative price impacts on the transaction prices of surrounding properties. The study concludes that the magnitude of social benefits associated with green building justifies the local provision of voluntary programs for green affordable housing, where housing is expensive relative to its basic cost of production.

ABSTRACTFour decades of advanced research about Non-Conventional Materials and Technologies (NOCMAT) such as bamboo and composites reinforced with natural fibers have shown that it is now possible to produce and use high performance NOCMAT. Bamboo and composites reinforced with vegetable fibers are capable, meeting most engineering demand in terms of strength, stiffness, toughness and energy absorption capability. The greatest challenge of the 21st century is the need for cost-effective, durable and eco-friendly construction materials that will meet the global needs of infrastructure regeneration and rehabilitation which alone can enhance the quality of life for all the people of the world. This paper summarizes some results of judicious combination of different matrix reinforced with vegetable fibers, especially bamboo. These sustainable ecological materials are strong, ductile and capable of absorbing large amounts of energy. They could find extensive applications in the engineering particularly in developing countries. Specifically, the development of durable composites reinforced with vegetable fibers and bamboo poses an important challenge to the science and skills of engineering. This challenge could create the most useful, eco-friendly construction materials backed by an endless supply of renewable natural resources. In addition the paper presents results of some ongoing research concerning bamboo and how vegetable fibers such as hemp plant, before the invention of Nylon was the most used materials in all aspects of human life around the globe and why it was banned.

Construction materials used in the nuclear industry used to be mainly heavy materials, including lead plates, radiation-resistant heavy concrete, etc. However, these materials are either toxic after a long time of use (lead) or difficult to construct (radiation-resistant heavy concrete) and their cost is rather high. Therefore, there is a need for the manufacturing of a new kind of material with good radiation resistance, which is light, easy to use, and costs less. Barium is less toxic and more cost-effective than lead. Due to the importance of barium compounds in radiation shielding, the study of gamma radiation interactions within these compounds becomes essential, so the most important part of such a study is the experimental one, which shows the effect of the barite powder in the radiation resistance of the mortar. The research results show that the higher the thickness and percentage of barite powder, the higher is the radiation resistance.

The key players in the construction industry around the globe are very enthusiastic in producing better construction materials that are cost-effective, durable, excellent thermal insulation, lightweight and long lasting without jeopardizing the environment. One of the best ways in producing such building materials are by incorporating industrial waste materials such as Empty Fruit Bunch (EFB) fiber in foamed concrete (FC). In recent years, the spotlight has been given towards the use of natural fiber reinforced concrete-based materials especially in Malaysia in a quest of economic and environmental upkeep particularly in the construction sector itself. Hence, this study intended to recognize the influence of Empty Fruit Bunch (EFB) fiber of four different contents (0.15%, 0.30%, 0.45% and 0.60 %) by mix volume on thermal properties of FC. There were three densities of 800kg/m3 , 1100kg/m3 and 1400kg/m3 we cast and tested. The mix design of FC (sand: cement: water) is fixed at the ratio of 1:1.5:0.45. The investigation focuses on three parameters which were thermal conductivity, thermal diffusivity and specific heat capacity. Results showed that the addition of EFB in FC plays an important role to improve the thermal performance holistically. The results demonstrated a great potential possesses by the EFB fiber to be utilized in cement-based materials such as the FC mix which is beneficial in reducing the thermal property or the transfer of heat in a produced concrete.

<p>In post-disaster reconstruction in underdeveloped countries, architects all too often create design solutions with little appreciation of the environment in which their solutions are expected to work. The disaster context for reconstruction is complex and irregular. Issues vary from lack of available resources; difficulty in transporting resources, inflation of costs for construction materials, corruption in the allocation of aid money and resources, language barriers, and the complexity of architects needing to meet the local socio-economic and cultural norms of each particular community. These are but a few of the complexities that need to be addressed when working in post-disaster reconstruction.  This paper draws on grounded theory field research and analysis of reconstruction efforts in Samoa after the tsunami in 2009 and category 2 Tropical Cyclone Evan (TC Evan) in 2012,; and category 5 Tropical Cyclone Winston (TC Winston) that devastated Fiji in 2016. This paper measures this research and analysis against literature and research and analysis of other post-disaster reconstruction case studies to come up with design iterations that are viable for the post-disaster context of Nanokonoko village, Viti Levu, Fiji.  This thesis investigates the ways that the architectural process of design can be used so that post-disaster communities have access to adequate, self-sustainable, and affordable housing. It does so by identifying the gaps and potential barriers that are created along the rebuilding work flow, then analyses and recommends an improved process for post-disaster reconstruction in underdeveloped countries for the architect and architecture to follow. By adopting the recommended process of reconstruction, the living situation of communities will significantly improve immediately following the disaster and in the long-term.  This thesis also explores the many other value adding roles that the architectural framework can benefit reconstruction through. By ensuring designs are culturally and socio-economically viable to the rural village of Nanokonoko and engages with the affected community in the early stages of recovery.</p>

Polymeric construction materials based on epoxy resin, carbon fillers, such as graphene nanoplates (GNP), carbon nanotubes (CNT) and fillers of inorganic nature – perlite, vermiculite, sand with improved electrophysical characteristics have been developed. The electrophysical propertieгs of composites obtained in various ways which differ according to the principle of injecting components have been investigated. GNP were obtained in two ways. Size distribution of GNP obtained by electrochemical method is 50 to 150 nm. The average particle size is up to 100 nm. It occurs that these particles tend to aggregate as it is shown by the method of dynamic light scattering. The GNP obtained by dispersing thermally expanded graphite in water in a rotary homogenizer have a particle size distribution of 400 to 800 nm if very small particles and large aggregates are absent. The second method of obtaining GNP is less energy consuming and requires fewer manufacturing cycles, so it is more cost-effective. Obtaining composites using aqueous suspensions of GNP is environmentally friendly. Due to the hydrophobic properties of its surface the electrical conductivity of the system which uses vermiculite is higher than one of that which uses perlite for composites with CNT and GNP. It has been found that the difference of electrophysical characteristics between two systems which contain the same amount of carbon filler is caused by the nature of the surface of dielectric components – sand. By changing the content of dielectric ingredients can expand the functionality of composites if use them for shielding from electromagnetic fields.
