Natural ventilation and air movement could-be considered under the heading of 'structural controls’ as it does not rely on any form of energy supply or mechanical installation, but due to its importance for human comfort, it deserves a separate section.
Natural ventilation is the process of supplying and removing air through an indoor space by natural means, meaning without the use of a fan or other mechanical system. It uses outdoor air flow caused by pressure differences between the building and its surrounding to provide ventilation and space cooling.

Zero energy building versus green building
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.
Passive cooling techniques are least expensive means of cooling a home which maximizes the efficiency of the building envelope without mechanical devices.

POULTRY HOUSE VENTILATION and Management.pptxMishkatKhan6
The day-to-day work on a commercial poultry farm varies depending on the type of farm: pullet, breeder, or broiler. Growers should understand the level of poultry care, management, and biosecurity measures required for the birds they are managing. Learn more in this second of a five-part series for new farmers in the commercial broiler industry.
For each type of commercial poultry farm, contract growers work under a management protocol from the integrator. Farmers considering commercial poultry should have a basic understanding of the daily requirements for each farm type to know which might best fit their goals. Growers should contact a local integrator to discuss options and talk to multiple current growers in the area before making a final decision.
The integrator owns the birds, provides the feed, veterinary services, and management supervision. The grower owns the grow-out facilities
and is responsible for day-to-day labor and bird care. All growers are encouraged to stay in contact with their field technicians for guidance and assistance.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.

Building Services - Efficient Energy Ventilation System
1.
2. Process of changing air in an enclosed space
A proportion of air should be withdrawn and replaced by the
fresh air continuously
Maintain the air purity, allow the oxygen to enter and water
vapors, smell to leave
Without proper ventilation, home will be suffer by damages,
most common-rot
3. Using less energy to have same kind of service
Instead of installing air-conditioner, use whole house fan
An efficient ventilation – establish hazard, satisfy user
comfort, be energy efficient, cost effective.
Heating, ventilation & air-conditioning (HVAC) ensure a
pleasant, comfortable & safe work environment
Significant energy and money saving can be made out
through when constructing new buildings, good strategies
presence optimize energy use in existing HVAC systems that
are reducing the demand for the service and ensuring the
good maintenance practices
4.
5. Passive Stack
Ventilation (PSV)
- Connected via near-vertical
ducts to ridge or other roof
terminals.
- Replacement dry air is drawn
into the room via background
ventilators and by air leakage
- Air is drawn up the ducts by a
combination of the stack effect
and wind effect
6. Installation process
Each wet room must have
their individual ducts
Make sure that the ducting
fixed securely to the
terminals
Cut the ducts to length, and
the angles of offsets should
not more than 45`
The ducts must be insulated
7. Possible Problems to
the System
Wastes heat and may cause draughts therefore
additional input grilles are required in living rooms to
prevent draughts
Have tendency to over or under ventilate depending
on weather conditions.
Window trickle vents and wall inlets are required.
Lack of pressure differences affecting airflow might
mean it’s necessary to use an open window or
additional central fan during warmer weather
8. Single Room Heat Recovery Ventilation (SRHRV)
Is also known as mechanical
ventilation heat recovery
recovers heat from the outgoing
air and pre-heats the incoming
air
moderate and balance the
temperature of the house
typically dual speed, providing
low-speed and high-speed
airflow
9. can be mounted on the
places like floor, joists or
plinth.
correctly located, wired
and commission on places
which have the easy
access to the main
electricity
Make sure there is an
adequate gap between the
exhaust vents and
incoming vents
Installation process
10. Possible Problems to
the System
Recirculation possible due to close proximity of supply
and extract grilles.
Too noisy to be installed in bedrooms or other quiet
places.
Fresh outdoor air and extracted air are indirectly in
contact with each other, therefore any pollutant could
be exchanged between the fresh and extracted air.
11. Mechanical Extract Ventilation (MEV)
Extracts air from ‘wet’
rooms continually
Less dependency on
background ventilators
Able to increase the speed
of the fan and extraction
rate as necessary, rather
than raising the extraction
rate for the whole building.
12. Installation process
ducts should be sealed using tape or sealant
can be mounted on the places which have anti-vibration mountings
between the unit and the structure.
13. Possible Problems to
the System
Requires ducting from the wet rooms and also requires
commissioning.
Air infiltration through the building envelope creates
easily draught in winter in cold climate.
The exhaust is usually from kitchens, bathrooms, and
toilets ventilation supply air flow is not evenly distributed
in the bed rooms and living rooms.
14. Positive Input Ventilation (PIV)

so may require extract ventilation ports in wet rooms,
these ports may have to remain constantly open
17. Intermittent Extract Fan &
Background Ventilators
provide rapid extraction of moisture and other pollutants.
operate intermittently under either occupant or automatic
control.
The fans can be either mounted in a window, ceiling or
external wall.
These fans do not run continuously, therefore the
background ventilators should be sized to provide adequate
continuous whole house ventilation.
18. Possible Problems to
the System
May produce lots of noise
Prone to occupant tampering & if
occupant is controlled, it may not be
used
Single façade dwellings require
additional background ventilators fitted
at low level
19. Whole House Mechanical
Ventilation with Heat
Recovery (MVHR)
usually combines supply and extract ventilation in one
system.
Systems considered here incorporate a heat exchanger.
provide the ideal ventilation system, delivering the required
ventilation rate almost independently of the weather
conditions
The system is typically dual speed, providing low-speed
continuous ‘trickle’ ventilation, and high-speed ‘boost’ extract
flow.
20. Possible Problems to
the System
An adequate level of air tightness must be achieved
In order to perform in optimum condition
Can be difficult in existing dwellings
Complexity for installation & commissioning
22. Maintaining the effectiveness of ventilation
regardless of wind direction
Ensuring constant supply of fresh air to maintain
