I came to know regarding this competition from rediff.com
The idea of Energy Efficient design is
to modulate the conditions such that they
are always within or as close as possible to
comfort zone.Modulations introduced by the
landscape,built form,envelope,materials and
other control measures bring the conditions
within the range throughout twenty four hours
cycle.
This is goal of Energy Efficient Architecture
Buildings, as they are designed and used today, contribute to serious environmental and economical problems because of excessive consumption of energy and other natural resources. The close connection between energy use in buildings and environmental damage arises because energy-intensive and monetarily expensive solutions sought to construct a building and meet its demands for heating, cooling, ventilation, and lighting cause severe depletion of invaluable environmental resources
Energy resource efficiency in new constructions
can be effected by adopting an
Integrated Approach To Building Design.
GREEN BUILDINGS
Uses less energy, water, natural resources

The goal of this discussion is to demystify building performance modeling. Computer-simulations give you a more complete picture of how various context and design factors can affect the performance of your space. Modeling information can help you analyze the impacts of your design decisions and determine how to most effectively meet project goals.
Energy modeling is also valuable tool used for code compliance and LEED points. Not to mention the fancy graphics that models produce to show your clientele your commitment to performance-based design.
This discussion will present various opportunities that can arise from building performance simulations with analysis at the early design, whole building, and building component levels. We will examine the following types of analysis:
• Climate
• Daylighting
• Massing and orientation
• Whole building energy usage forecast
• Fenestration design
• Façade development
• Zone level energy performance
• Baseline and design case models
• System selection and optimization

A one day symposium on zero/low carbon sustainable homes took place at The University of Nottingham on the 24th October, 2012. The event offered professionals within the construction industry a unique opportunity to gain added and significant insight into the innovations, policies and legislation which are driving the construction of zero/low carbon energy efficient homes both here in the UK and elsewhere in Europe. It explored solutions to sustainability issues “beyond” the zero carbon agenda. BZCH followed on from the successful ‘Towards Zero Carbon Housing’ symposium the University hosted in 2007. This event is part of the Europe Wide Ten Act10n project which is supported by the European Commission Intelligent Energy Europe.
What Energy Sources are available & how do they work?
Civilizations are based on the fuels they use to power themselves. The fuel determines the technologies used, and the technologies determine the lifestyles, economies, and eventually the entire culture. So the transition to sustainable fuels is critical if we wish to design sustainable cultures.
This class explores which fuels can be considered 'renewable' & under which circumstances.
Also we look into the various transformer technologies which are needed to make this energy available to us, how they are most effectively used and we explore what a truly 'solar-powered civilization' might look like.
This presentation is a basic introduction to the concepts underlying carbon neutral design. It looks at a LEED Platinum building that is also a carbon neutral building for some ideas as to how to achieve this goal.

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.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
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.

A Strategic Approach: GenAI in EducationPeter 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.

2. “The world will not evolve past its current state of crisis
by using the same thinking that created the
situation.”
– Albert Einstein
…the world of DESIGN needs some Radical thinking!
4. Radical CONFLICT!??
#1 – GLOBAL WARMING – too much CO2
#2 – RUNNING OUT OF OIL (oil causes CO2 )
5. • If we ran out of OIL right away…
• We would solve part of the Global Warming
problem….
• PROBLEM: there is still LOTS of COAL, and
COAL is even dirtier….
6. POLLUTION IS AN ACT OF DESIGN
Remember, EVERYTHING that is called 'disposable' was DESIGNED from
day one to be garbage--as its PRIMARY and overriding design
consideration.”
8. Radical PHILOSOPHY!??
WASTE = FOOD
(the human race is the only species to DESIGN things
with the INTENTION that they become GARBAGE!)
9. MIMIC NATURAL CYCLES
Design for a closed loop where WASTE becomes
FOOD and FEEDS back into a healthy cycle….
compostable end product
10. Radical PROPOSITION!??
DESIGN FOR DISASSEMBLY
So that we can take things (even buildings!)
apart and easily repair or reuse them
REUSE MEANS LESS ENERGY THAN RECYCLE
11. MIMIC OTHER INDUSTRIES
DESIGN BUILDINGS TO COME APART SO THAT THEY
CAN BE REPAIRED, REUSED AND RECYCLED – EASILY!
14. Radical GREEN THINKING
• Radical problems need Radical solutions
• Radical solutions are seldom thought about
until there are…
• Radical CATALYSTS!
Do you remember August 14, 2003?
15. Radical Wake Up Call
The Northeast Blackout of 2003 was a massive
widespread power outage that occurred
throughout parts of the Northeastern and
Midwestern United States, and Ontario, Canada
on Thursday, August 14, 2003, at approximately
4:15 pm EDT (20:15 UTC). At the time, it was the
most widespread electrical blackout in history.
The blackout affected an estimated 10 million
people in the Canadian province of Ontario and
45 million people in eight U.S. states.
17. Radical PROBLEM!
• No power…
• Hot August weather… or
• Cold January temperatures…
• Hooked on electricity, heat and A/C
• What buildings/environment/systems
“worked”?
• What buildings/environment/systems
“didn’t” work?
19. Radical AWAKENING!
• Grid and energy dependent

• OPERABLE WINDOWS WORKED!
• NATURAL VENTILATION WORKED!
• SHADE WORKED!
• SUNLIGHT WORKED!
• DAYLIT SPACES WORKED!
• WALKABLE NEIGHBOURHOODS WORKED!
• BICYCLES WORKED!
20. Radical THOUGHT!??
MAYBE WE SHOULD BEGIN TO DESIGN OUR
BUILDINGS/ENVIRONMENTS IN REVERSE!
Start with a basic UNPLUGGED building
21. Four Key Steps:
Radical Steps!
#1 - start by UNPLUGGING the building
Then…
#2 – heat only with the sun
#3 – cool only with the wind and shade
#4 – light only with daylight
USE the ARCHITECTURE first, and mechanical systems only to
supplement what you cannot otherwise provide.
#5 – USE RENEWABLE CLEAN ENERGY BEFORE HOOKING
UP TO NATURAL GAS, OIL OR THE REGULAR ELECTRICAL
GRID (with all of its nastiness – including CO2)
22. Radical IS Passive…
PASSIVE DESIGN is where the building uses
the SUN, WIND and LIGHT to heat, cool and
light

24. Smaller–is better.is Better!
Radical Thought Smaller
- Simple!…less building results in less embodied
carbon; i.e. less carbon from materials used in the
project, less requirements for heating, cooling and
electricity….
- Re-examine the building program to see what is
really required
- How is the space to be used?
- Can the program benefit from more inventive
double uses of spaces?
- Can you take advantage of outdoor or more Calculating your
seasonally used spaces? “ecological footprint”
- How much building do you really need? … can naturally extend to
an understanding of your

52. Bio-climatic Design: HOT-HUMID
Where warm to hot stable conditions
predominate with high humidity throughout
the year.
RULES:
- SOLAR AVOIDANCE : large roofs with
overhangs that shade walls and to allow
windows open at all times
- PROMOTE VENTILATION
- USE LIGHTWEIGHT MATERIALS that do not
hold heat House in Seaside, Florida
- use STACK EFFECT to ventilate through high
spaces
- use of COURTYARDS and semi-enclosed
outside spaces

53. Bio-climatic Design: TEMPERATE
The summers are hot and humid, and the
winters are cold. In much of the region the
topography is generally flat, allowing cold
winter winds to come in form the
northwest and cool summer breezes to
flow in from the southwest. The four
seasons are almost equally long.
RULES:
- BALANCE strategies between COLD and
HOT-HUMID
- maximize flexibility in order to be able to IslandWood Residence, Seattle
modify the envelope
- understand the natural benefits of SOLAR
ANGLES that shade during the warm
months and allow for heating during the
cool months
