Environmental Impact Of Building Materials: A Study Of Energy Efficient Materials For Building Facade Systems In Mumbai City.
May 2015,
Environmental architecture, Sustainable material. Life cycle assessment. Building Materials, Mumbai
Presently most electrical/electronic equipment (EEE) is not designed for recycling, let alone for circulation. Plastics in these products account for 20% of material use, and through better design, significant environmental and financial savings could be gained.
Technological solutions and circular design opportunities already exist, but they haven’t been implemented yet.
Some challenges, such as ease of disassembly, could be resolved through better communication and by sharing learnings across the value chain.
Instead of WEEE, we should focus on developing CEEE: Circular Electrical and Electronic Equipment.
The case examples of this report show how different stages of the lifecycle can be designed so that plastics circulation becomes possible and makes business sense.
Green buildings have gained popularity in recent years. While they have higher initial costs than traditional buildings, studies have shown that green buildings reduce energy costs by 30% on average and increase productivity. Productivity gains are largely due to improved indoor environmental quality (IEQ) in green buildings, which provide better lighting, airflow, and temperature control. A case study of a building in Pennsylvania found productivity increased by over 60% after improving IEQ standards. Green buildings also use 30% less energy on average due to better insulation and efficiency. While the upfront costs of green buildings are higher, the long term savings on energy and increases in productivity outweigh the initial investment.
This document discusses green buildings and sustainability. It defines green building as optimizing efficiency in using energy, water and other resources throughout a building's lifecycle. The key principles discussed include sustainable site design, water and energy efficiency, indoor environmental quality, material efficiency. Green buildings provide benefits like reduced costs, improved health and productivity. Rating systems like LEED and IGBC are also summarized.

TRANSFORMING TO SUSTAINABLE BUILDING AND COST ANALYSIS OF PARAMETERS FOR GREE...IAEME Publication
In today's era of urbanization, the environment has been disturbed by human beings. Environmental imbalance is produced because of various activities created by us. The construction industry is performing an enormous role in this. While building procedures and after construction because of faulty preparation, pollution is produced in addition to many natural resources being wasted or exploited. A green Building design offers solutions to problems and contributes to keeping the surroundings clean, green, and eco-friendly. The green building momentum began in 1990 with the establishment of 1st green rating system - BREEAM (Building Research Establishment Environment Assessment Method) in the U.K., then after followed by U.S. Green Building Council (USGBC) in 1993 led a rating system' LEED' (Leadership in Energy & Environment Design). The green building and sustainable development moment is an entirely new environmentally friendly lifestyle that is steadily emerging worldwide and in India. In India, the Indian Green Building Council (IGBC) started in 2001 with its rating and certification process. In the current research of current building taking advantage of the unlimited resource, e.g., utilizing sunlight through photo-voltaic tools and led lighting effects, numerous additional methods to transform the structure on the green building and also concentrates on the beneficial results, as well as results after the structure, is changed to green building, Case 1: The study is conducted on Residential complex of G+3 buildings having total flats of 27nos, Situated in dist.- Thane, state - Maharashtra Case 2: The project deals with studying the case study of g+4 storey building eco-friendly ideas, a set case in point of an eco-friendly building that could well be healthy for the people inside in addition to exterior.

Courses teach green engineering techniques, and centers evaluate alternative technologies. Embracing green engineering may reduce health/safety risks, costs, and gain public support while enabling innovation.
The document discusses green technologies and their importance. It defines green technology as technologies that minimize environmental impacts and reduce the use of natural resources. Some key areas of green technology discussed include green building, green nanotechnology, green chemistry, green IT, and green energy. Green technologies are important because they are more sustainable and help address issues like resource depletion, pollution, and climate change. The future of green technology is promising as governments and the private sector increasingly invest in these sustainable technologies.
Sustainable Development of Green Building on Design Efficiencybadrulidham
Green building aims to reduce environmental impact through sustainable design, construction, and operation. The design stage significantly impacts costs and performance by minimizing total environmental impact over the building's lifecycle. Benefits include reduced operating costs, improved occupant health and productivity, and protection of biodiversity. However, implementing green building faces challenges like lack of government incentives, low public awareness, and high initial costs. Suggestions are provided to address issues like poor maintenance, unsuitable locations, and unqualified architects.

Results of Preliminary evaluation
Electricity and LPG usage are the most impact on
production process
LPG usage yields technical possibility
Reduction of loss of raw material yields high technical
and economic possibilities.
Water usage has the high impact on environment

Exquisite evaluation
Mass balance in each steps of process is performed
Step1: Boiling and cleaning pigs
Cause: 1. Loss of water quantity while waiting for various
components of pig
2. In case of high production capacity (~120 pigs), water
pressure in cleaning is not sufficient resulting in no
water used and other steps being stopped.
Method to reduce loss
1. Install injector at the end of hose
2. Install water pump to increase water pressure
3. Control water pressure in water reservoir more than 0.5
bar by adjusting pressure difference of water generating
system to high generate water

Step2: Freezing any components of pig
Cause: Components of pig before delivering to freezing room
have high humidity. Freezing room have to reduce water
temperature which results in excessively used electricity
Method to reduce loss
Drain water away from freezing room
Step3: Cutting any components of pig
Cause: 1. Some components of pig fall on area of slice machine
2. Water tap used for cleaning hand
has oversize resulting in loss of
water
Method to reduce loss
Install panels to prevent falling of
pig’s components
Install water distributors to increase water volume for cleaning
hand

Step5: Cooling Tower
Cause: - Efficiency of cooling tower is decreased due to dregs and
moss generated
Method to reduce loss
- Cleaning cooling pack

Case Study III Green Buildings
School of Renewable Energy
Technology (SERT) has missions to
research and development of renewable
energy including energy conservation
which relates to Green Building.
Naresuan University (NU) has been
assigned SERT to take responsibilities to
set model scheme of Green Building for
all buildings around NU area.

74. 7474School of Renewable Energy Technology, Naresuan University
Defining Green Building
has friendly environmental construction process without
impact on ecosystem
gives energy savings
has suitable air, humidity, and lighting qualities
use low-energy construction or recycled material
apply modern and innovative technologies to building

Previous 3 Case studies of managing buildings to be green
building is set to be model scheme to obtain complete Green
Building between 2013-2016.
For the rest of buildings around NU area, We (SERT) are
ongoing to manage them to be green building soon such as
student dormitories and various Faculties.
We try to use renewable energy technology applying to
Green Building for NU Green Building Project and hope to
collaborate in research between Thai and Indonesia in theme
of “Energy Efficiency” in the near future
