Within landscaping and architecture, reusing wood helps decrease environmental impacts while providing financial and educational benefits. However, several factors influence the potential for reprocessing leftover wood. Contamination from dirt and other materials makes wood difficult to reuse for high-quality products. The costs of sorting, cleaning, and transporting leftover wood also often outweigh the financial benefits. Alternative wood sources may be cheaper and easier to obtain and process than scattered and contaminated leftover wood. Overcoming these technical and economic challenges would allow leftover wood to play a greater role in producing new wood-based materials and products.

A Theoretical Study on Green Concrete Constructionijtsrd
Concrete which are taken from the demolished structures or from concrete waste which are considered to be eco friendly and using it for the purpose of another building construction is called as green concrete construction. This helps to make the future construction eco friendly and also reduce the emission of CO2. Now a days global warming is the major drawback of whole world which is directly or indirectly caused by the civil engineering field. The world consumes concrete more next to water. So it is the duty of every civil engineer to go along the disadvantages of green house gas emission and to reduce their effects in environment. This can be sought by using the eco friendly materials and also the eco friendly waste concrete available in earth. This journal paper would provide the ideas of green construction and also helps to induce the engineers choice of construction.

Green Buildings Overview and Analysis of Energy Efficient Buildingpaperpublications3
Abstract: The challenges our planet faces, particularly climate change and sustainable economic development, are global in nature and so require global solutions. The building sector, which consumes as much as 40% of world’s energy, 12% of its water and contributes 40% of its waste sent to landfill, is the major part of this global problem. Reducing energy use in buildings saves resources and money while reducing pollution and CO2 in the atmosphere. It also leverages even greater savings at power plants. For the average 33-percent-efficient coal-fired power plant, saving a unit of electricity in a building saves three units of fuel at the power plant. So to reduce green house gas emission, government promotes new buildings construction and to retrofit existing buildings while satisfying low energy criteria. This means improving energy efficiency of buildings and energy systems, developing sustainable building concepts and promoting renewable energy sources. “Green” or “sustainable” buildings use key resources like energy, water, materials, and land more efficiently than buildings that are just built to code. With more natural light and better air quality, green buildings typically contribute to improved employee and student health, comfort, and productivity. A green building depletes the natural resources to the minimum during its construction and operation. In this paper an over view of green building is discussed.

Living Green Shell: Urban Micro-Vertical FarmCSCJournals
In order to reduce the urban heat island effect and increase cooling insulation, certain innovative cities rely on the benefits of vertical greening system. However, finding the space in a highly- developed city such as Hong Kong and Taiwan is a significant challenge. Facing the same challenge, cities like New York, Tokyo and Singapore, develop vertical greening system such as green walls, green roof, or urban agriculture to maximize the greening capacity. However, the green-roof development in Taiwan faces the challenge of the unique culture of architectural additions, known as sheet metal housing. The roof-top sheet metal housing is commonly used in most of the Taiwanese communities and occupies the roof space. Moreover, this sheet metal not only limits the scale of greening development, it also increases the indoor temperature and energy consumption with its heat-transfer nature. According to the research, the Living Green Shell functions as shelter, cooling insulation, air purifier and helps improve cooling efficiency in conjunction with the concept of vertical farm. Through the BIM simulation evaluations, the research focuses on how the cooling insulation of the Living Green Shell (LGS) over the sheet metal buildings could give a better energy-saving efficiency. The micro-vertical farm system is evolving from LGS 1.0 to the final version, LGS 3.0 to improve related functions. The LGS also provides edible vegetables and produces solar energy via the mini-solar bites. With the sheet metal housing's easily fabricated nature, the housing could be integrated with the LGS devices and led to a broad implementation in Taiwan with proper promoting.

Comparative Analysis of Coconut shell Concrete to Traditional ConcreteCompara...IJRTEMJOURNAL
It is found that so many wastes which can be used in traditional concrete like e-wastes, rubber
tyre waste, glass waste etc. The coconut shell is also a main waste which can be used in traditional concrete.
Generally, coconut shells are used in traditional concrete in the form of viz., coconut shell aggregate and
coconut shell fiber. This paper describes coconut shells are used as replacement of coarse aggregates. The
compressive and flexural strength test where taken on 10%, 20% and 30% replacement of coarse aggregate to
coconut shells. It is observed that the compressive strength of concrete is reduced in some extent and the
flexural strength also reduced as replacement of coconut shell is increased, but the 10% replacement is possible
to use in construction work and 20% and 30% replacement are possible to use for less important construction
work under some conditions.
It is found that, workability of concrete is increased than traditional concrete as percentage replacement is
increased. Total cost of concrete is get reduced by replacement of coarse aggregate to coconut shells. The
volume of concrete is also increased as replacement is increased, hence, the total quantity of concrete required
is getting reduced and the cost is again getting reduced. This paper supports the “SWACHHA BHARAT
ABHIYAN” carried by our Hon. Prime Minister Narendra Modi.
Finally, this paper concluded that, the Coconut Shell is possible to use for construction work as coarse
aggregate under some conditions economically. It is majorly used for construction of small huts, watchman
cabin, farm house in forest areas and small houses etc.
The document provides an agenda for a green building training. The agenda includes field trips, quizzes, and presentations on topics like green materials, life cycle analysis, green certifications, green specifications, and LEED rating systems. It also discusses concepts like greenwashing, defines what makes a material green, and summarizes standards for green building product certification.
Green building aims to reduce environmental impacts through efficient resource use, protection of occupant health, and reduction of waste and pollution. It focuses on siting, design, construction, operation, maintenance, and demolition to lessen impacts on human health and the environment. Globally, buildings are responsible for large shares of energy, water, and materials consumption as well as greenhouse gas emissions. Green building practices and technologies aim to cut these impacts by optimizing principles like energy efficiency, water efficiency, and materials selection.

Facing the same challenge, cities like New York, Tokyo and Singapore, develop vertical greening system such as green walls, green roof, or urban agriculture to maximize the greening capacity. However, the green-roof development in Taiwan faces the challenge of the unique culture of architectural additions, known as sheet metal housing. The roof-top sheet metal housing is commonly used in most of the Taiwanese communities and occupies the roof space. Moreover, this sheet metal not only limits the scale of greening development, it also increases the indoor temperature and energy consumption with its heat-transfer nature. According to the research, the Living Green Shell functions as shelter, cooling insulation, air purifier and helps improve cooling efficiency in conjunction with the concept of vertical farm. Through the BIM simulation evaluations, the research focuses on how the cooling insulation of the Living Green Shell (LGS) over the sheet metal buildings could give a better energy-saving efficiency. The micro-vertical farm system is evolving from LGS 1.0 to the final version, LGS 3.0 to improve related functions. The LGS also provides edible vegetables and produces solar energy via the mini-solar bites. With the sheet metal housing's easily fabricated nature, the housing could be integrated with the LGS devices and led to a broad implementation in Taiwan with proper promoting.

Comparative Analysis of Coconut shell Concrete to Traditional ConcreteCompara...IJRTEMJOURNAL
It is found that so many wastes which can be used in traditional concrete like e-wastes, rubber
tyre waste, glass waste etc. The coconut shell is also a main waste which can be used in traditional concrete.
Generally, coconut shells are used in traditional concrete in the form of viz., coconut shell aggregate and
coconut shell fiber. This paper describes coconut shells are used as replacement of coarse aggregates. The
compressive and flexural strength test where taken on 10%, 20% and 30% replacement of coarse aggregate to
coconut shells. It is observed that the compressive strength of concrete is reduced in some extent and the
flexural strength also reduced as replacement of coconut shell is increased, but the 10% replacement is possible
to use in construction work and 20% and 30% replacement are possible to use for less important construction
work under some conditions.
It is found that, workability of concrete is increased than traditional concrete as percentage replacement is
increased. Total cost of concrete is get reduced by replacement of coarse aggregate to coconut shells. The
volume of concrete is also increased as replacement is increased, hence, the total quantity of concrete required
is getting reduced and the cost is again getting reduced. This paper supports the “SWACHHA BHARAT
ABHIYAN” carried by our Hon. Prime Minister Narendra Modi.
Finally, this paper concluded that, the Coconut Shell is possible to use for construction work as coarse
aggregate under some conditions economically. It is majorly used for construction of small huts, watchman
