Types of embodied energy· Initial embodied energy; and· Recurring embodied energy
The initial embodied energy in buildings represents the non-renewable energy consumed in the acquisition of raw materials, their processing, manufacturing, transportation to site, and construction. This initial embodied energy has two components:Direct energy the energy used to transport building products to the site, and then to construct the building; andIndirect energy the energy used to acquire, process, and manufacture the building materials, including any transportation related to these activities.

This modular housing based in Belapur, New Mumbai, is designed by Ar. Charles Correa. This project, which was constructed in the 1980s, stands as a perfect example of affordable and high density housing, which is the need of the hour.
Many building materials are used for construction and different methods are followed. Each of these building materials has a unique embodied energy. Out of these materials, Roofing material constitute one of the major energy consuming components of the building. Effective utilization of available energy and its conservation is global challenge. For a developing country like India, the increasing demand of energy has created a scope for the study embodied energy of alternative roofing technique and their advantages for the sustainable building construction. The total embodied energy of a building can be reduced significantly by using alternate roofing technique such as RCC Filler slab which has lower embodied energy value.
Filler slab technology is a simple and a very innovative technology for a slab construction. The filler slab is based on the principle that for roofs which are simply supported, the upper part of the slab is subjected to compressive forces and the lower part of the slab experience tensile forces. Concrete is very good in withstanding compressive forces and steel bears the load due to tensile forces. Thus the lower tensile region of the slab does not need any concrete except for holding the steel reinforcements together. Hence concrete in the bottom region of solid RCC slab is replaced by an energy efficient and cost effective material. With reduced consumption of building material for roofing, the cost of the building can be reduced predominantly.

Green building is environmentally-conscious construction and operation of a building structure.
A green Building uses less energy, water and other natural resources creates less waste & Green House Gases and is healthy for people during living or working inside as compared to a standard Building. Another meaning of Green Structure is clean environment, water and healthy living.
Materials are the starting point for architectural design.An architect needs to understand the nature of materials and their possibilities and limitations before they can be used to create buildings and spaces.
Sustainable Civil Engineering Solutions through Technological InnovationsIRJTAE

innovations and their applications in achieving sustainability goals in construction, infrastructure development,
and urban planning. Through a comprehensive review of literature and case studies, this paper examines how
advancements in technology are reshaping the field of civil engineering and enabling the design, construction,
and management of infrastructure with a focus on sustainability. Key areas of innovation explored include green
building materials, energy-efficient construction techniques, smart infrastructure systems, and digital modelling
and simulation tools.
HOSPITAL
A hospital is a health care institution providing patient treatment by specialized staff and equipment..
Hospitals are usually funded by the public sector, by health organizations (for profit or nonprofit), health insurance companies, or charities, including direct charitable donations.
Historically, hospitals were often founded and funded by religious orders or charitable individuals and leaders.
Today, hospitals are largely staffed by professional physicians, surgeons, and nurses, whereas in the past, this work was usually performed by the founding religious orders or by volunteers.
Hospitals vary widely in the services they offer and therefore, in the departments (or "wards") they have. They may have acute services such as an emergency department or specialist trauma centre, burn unit, surgery, or urgent care. These may then be backed up by more specialist units such as:
Emergency department
Cardiology
Intensive care unit
Pediatric intensive care unit
Neonatal intensive care unit
Cardiovascular intensive care unit
Neurology
Oncology
Obstetrics and gynecology
Adolescent medicine Allergy/Immunology Anesthesia
Cardiac Surgery
Center for Communication Enhancement Critical Care medicine

Gynecology
Infectious Diseases
Nephrology
Neurology
Neurosurgery
Newborn medicine
Ophthalmology
Otolaryngology and Communication Enhancement Plastic and Oral Surgery Psychiatry
Pulmonary and Respiratory Diseases
Radiology
Rheumatology

Surgery
Urology
Some hospitals will have outpatient departments and some will have chronic treatment units such as behavioral health services, dentistry, dermatology, ward, rehabilitation, and physical therapy.
Common support units include a dispensary or pharmacy, pathology, and radiology, and on the non-medical side, there often are medical records departments, release of information departments, Information Management (IM)(aka IT or IS), Clinical Engineering (aka Biomed), Facilities Management, Plant Ops (aka Maintenance), Dining Services, and Security departments
Housing is a basic human requirement of any civilised society. With the growth of urbanisation, cities have been expanding alarmingly in the last few decades, which has resulted in haphazard growth of urban areas as well as acute housing shortage.

Green architecture defines an understanding of environment-friendly architecture under all classifications, and contains some universal consent, It may have many of these characteristics:
x Ventilation systems designed for efficient heating and cooling
x Energy-efficient lighting and appliances
x Water-saving plumbing fixtures
x Landscapes planned to maximize passive solar energy
x Minimal harm to the natural habitat
x Alternate power sources such as solar power or wind power
x Non-synthetic, non-toxic materials
x Locally-obtained woods and stone
x Responsibly-harvested woods
x Adaptive reuse of older buildings
x Use of recycled architectural salvage
x Efficient use of space1.Interaction
The relationships between construction site and architecture, green space and architecture, and also with people and form are emphasized here.
2.Form
With the new design thinking and process, concern for sustainable needs and computer aided technology, the form of architecture, or the use of building envelops may be redefined in the digital-green environment.
3.Construction:
With the aid of computer technology and 3D modelling techniques

Housing and Urban Planning Department was established to ensure planned development of urban areas and create an enabling environment to provide affordable housing.
India needs about 19 million low-cost homes - roughly defined as costing a million rupees ($16,700) and below - to shelter an urban population expected to nearly double to 600 million by 2030 from 2011.
Samajwadi Awas Yojana is one the most popular and affordable government scheme which is launched for urban areas for full filling the needs of Houses in very affordable price for different categories of Uttar pradesh.
Uttar pradesh government initiated this samajwadi avas yojana by the help of Public private partnership. Chief Minister of uttar pradesh has already given there approval regarding the Samajwadi Avas Vikas Yojana.

amount of energy used is equal to amount of renewable energy created on the site
reduce carbon emissions & reduce dependence on fossil fuels
Buildings that produce a surplus of energy over the year are called “Energy Surplus Buildings”
During the last 20 years more than 200 reputable projects claiming net zero energy balance have been realized all over the world.
NZEB buildings consequently contribute less overall greenhouse gas to the atmosphere than similar non-ZNE buildings. They do at times consume non-renewable energy and produce greenhouse gases, but at other times reduce energy consumption and greenhouse gas production elsewhere by the same amount. Traditional buildings consume 40% of the total fossil fuel energy in all over the world and are significant contributors of greenhouse gases.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Low embodied energy
1. LOW EMBODIED ENERGY SUSTAINABLE
BUILDING MATERIALS AND
TECHNOLOGIES
Presented by
Aiman
Sarah
Nazia
Sufyan
Hamzah
2. What is Embodied energy ?
The embodied energy (carbon) of a building material can be
taken as the total primary energy consumed (carbon
released) over its life cycle.
This would normally include (at least) extraction,
manufacturing and transportation.
3. Types of embodied energy
· Initial embodied energy; and
· Recurring embodied energy
The initial embodied energy in buildings
represents the non-renewable energy
consumed in the acquisition of raw
materials, their processing,
manufacturing, transportation to site, and
construction. This initial embodied energy has
two components:
Direct energy the energy used to transport
building products to the site, and then to
construct the building; and
Indirect energy the energy used to acquire,
process, and manufacture the building materials,
including any transportation related to these
activities.
4. RECURRING EMBODIED ENERGY
The recurring embodied energy in buildings
represents the non-renewable energy consumed to
maintain, repair, restore, refurbish or replace
materials, components or systems during the life
of the building.
5. How is embodied energy measured?
Embodied energy is measured as the quantity of non-
renewable energy per unit of building material, component
or system.
It is expressed in megajoules (MJ) or gigajoules (GJ) per
unit weight (kg or tonne) or area (m2) but the process of
calculating embodied energy is complex and involves
numerous sources of data.
6. UNITS OF MEASUREMENT
Standard Unit for Embodied Energy: MJ/ kg material
Standard Unit for Carbon emissions: Kg CO2/ kg material
Functional units:
MJ/ m3 material
Kg CO2/ m3
material
7. Energy consumption in buildings occurs in five phases.
• The first phase corresponds to the manufacturing of building materials and
components, which is termed as embodied energy.
• The second and third phases correspond to the energy used to transport
materials from production plants to the building site and the energy used in
the actual construction of the building, which is respectively referred to as grey
energy and induced energy.
8. • Fourthly, energy is consumed at the
operational phase, which corresponds
to the running of the building when it is
occupied.
• Finally, energy is consumed in the
demolition process of buildings as
well as in the recycling of their parts,
when this is promoted.
9. CRADLE-TO-GATE
is an assessment of a partial product life cycle from resource extraction (cradle) to the factory gate
- Energy inputs from:
• Extraction of raw materials
• Transportation to factory
• Manufacture of product / components
• Assembly of product / system
• Transportation to site / point of sale
• Installation / construction
• Maintenance
• Replacement
• Disposal / re-purposing / recycling
13. Certified wood is the only product that can carry the added value of chain-of-
custody certification—which confirms that it came from sustainably managed,
third-party certified forests. Similar to tracking packages, chain-of-custody tracks
forest products through all phases of ownership, processing and transportation,
from the forest of origin to the end consumer. The chain-of-custody system is
verified through an independent third-party audit. The result is that buyers know
their building materials are coming from forests managed in accordance with strict
sustainable forest management certification standards—and not from controversial
sources such as illegal logging.
The concrete and steel industries have no third-party sustainability certification or
chain-of-custody certification. However, progress is being made in responsible
procurement. In particular, some steel companies are reportedly encouraging
suppliers to adopt responsible practices and/or management systems certified to
ISO standards. In certain cases, companies dedicate online resources to screening
potential suppliers and to promoting and monitoring the performance of existing
vendors. Steel is often imported from developing countries and the absence of a
third-party certification program makes it impossible to accurately assess the
environmental and social impacts of steel products.

18. Embodied energy depends on:
• efficiency of the individual manufacturing process
• the fuels used in the manufacture of the materials
• the distances materials are transported
• the amount of recycled product used.
19. When selecting building materials, the
embodied energy should be considered with
respect to:
1. the durability of building materials
2. how easily materials can be separated
3. use of locally sourced materials
4. use of recycled materials
5. specifying standard sizes of materials
6. avoiding waste
7. selecting materials that are manufactured using
renewable energy sources.
20. Buildings account for 30 to
40% of total global energy usage.
(United Nations Environmental
Programme)
The construction sector is
responsible for :
40% of the consumed
resources
40% of CO2 emissions
40% of waste (construction and
demolition) (UNCHS/ Habitat)
ENVIRONMENTAL IMPACT OF THE BUILDING
INDUSTRY
Cities take about 2 % of the land surface but consume 75 % of the world’s natural
resources.

26. Guidelines for reducing embodied energy
1. Design for long life and adaptability, using durable
low maintenance materials.
2. Ensure materials can be easily separated.
3. Modify or refurbish instead of demolishing or adding.
4. Ensure construction wastes and materials from
demolition of existing buildings are reused or
recycled.
5. Use locally sourced materials (including materials salvaged
on site) to reduce transport.
6. Select low embodied energy materials (which may
include materials with a high recycled content),
preferably based on supplier-specific data.
27. 1. Avoid wasteful material use. For example, specify standard
sizes wherever possible (windows, door, panels) to avoid using
additional materials as fillers. Some energy intensive finishes,
such as paints, often have high wastage levels so try to buy only
as much as you need.
2. Ensure offcuts are recycled and use only sufficient
structural materials to ensure stability and meet
construction standards.
3. Select materials that can be reused or recycled easily at the end
of their lives using existing recycling systems.
4. Give preference to materials that have been
manufactured using renewable energy sources.
5. Use efficient building envelope design and fittings to minimise
materials (e.g. an energy efficient building envelope can
downsize or eliminate the need for heaters and coolers, water-
efficient taps can allow downsizing of water pipes).
Guidelines for reducing embodied energy
28. REUSE AND RECYCLING
Reuse of building materials commonly saves about 95% of embodied energy that would
otherwise be wasted. However, some materials such as bricks and roof tiles may be damaged
when reused.
