Prehistoric Times- Mesopotamian Architecture Temples were often the most central and important buildings in Mesopotamian city states. They were usually devoted to individual deities and could be quite elaborate if the city was rich. The largest temples were ziggurats.

These towers were one of the first forms of architecture created by the Mesopotamians, and were also home to the priest and high-status officials and usually dedicated to a specific god in Mesopotamian religion. The towers were constructed at such a large elevation, for protection from floods, and to practice religious ceremony on the shrines located at the very top. Each Ziggurat was interconnected with other buildings to form a "complex" like form of building, a court yard usually resided in the centre of these complexes.

Section:2 - Building Materials, Construction & Management 1.Building Materials Stone Sedimentary stone came from organic elements such as glaciers, rivers, wind, oceans, and plants. Tiny sedimentary pieces broke off form these elements and accumulated to form rock beds. They were bonded through millions of years of heat and pressure.

Metamorphic stones originate from a natural form of one type of stone to another type through the mixture of heat, pressure, and minerals. The change may be a development of a crystalline formation, a texture change, or a colour change.

Igneous stones are mainly formed through volcanic material such as magma. Underneath the Earth's surface, liquid magma cooled and solidified. Mineral gases and liquids penetrated into the stone and created new crystalline formations with various colours.

Stone Textures There are many different types of stone available today. When stone is ordered, it is fabricated with a particular type of surface. There are six main type of surfaces that are selected: Honed: Provides a flat to low sheen gloss. Different levels of gloss can be selected. This surface is very smooth, but often very porous. This texture is common in high traffic buildings. Honed floors should always be protected with Penetrating Sealer because it has wide-open pores. Honed stone colours are not as vibrant as polished stone.

Polished: A glossy surfaces that wears away with time due to heavy foot traffic and using improper maintenance procedure. This surface is very smooth and not porous. The reflectively of polished crystals brings out the brilliant colors and grains of natural stone. The shine comes from the natural reflection of the stone's crystals. The shine is due to polishing bricks and polishing powders used during fabrication.

Section:3 - Building & Structures Principle of Strength of Materials Stress (σ) When a material is subjected to an external force, a resisting force is set up within the component. The internal resistance force per unit area acting on material or intensity of the forces distributed over a given section is called the stress at a point. It uses original cross-section area of the specimen and also known as engineering stress or conventional stress.

Tensile stress (σt) If σt > O the stress is tensile. i.e. The fibres of the component tend to elongate due to the external force. A member subjected to an external force tensile P and tensile stress distribution due to the force is shown in the given figure.

Compressive stress (σc) If σc < O the stress is compressive. i.e. The fibres of the component tend to shorten due to the external force. A member subjected to an external compressive force P and compressive stress distribution due to the force is shown in the given figure.

Shear stress When forces are transmitted from one part of a body to another, the stresses developed in a plane parallel to the applied force are the shear stress. Shear stress acts parallel to the plane of interest. Forces P is applied transversely to the member AB as shown. The corresponding internal forces act in the plane of section C and are called shearing

Section:4 - Environmental Planning & Design Environmental Planning Glossary Trophic level: steps in food chain that show feeding and niche relationships among organisms; trophic=nourishment Autotrophs: are those organisms that are able to make energy-containing organic molecules from inorganic raw material by using basic energy sources such as sunlight. Plants are the prime example of autotrophs, using photosynthesis Heterotrophs: All other organisms must make use of food that comes from other organisms in the form of fats, carbohydrates and proteins. These organisms which feed on others are called heterotrophs.

Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their environments.

These molecules can be organic (chemoorganotrophs) or inorganic (chemolithotrophs). The chemotroph designation is in contrast to phototrophs, which utilize solar energy. E. g Nitrifying Bacteria is a chemotroph.

Saprophytes: are more generally plants, fungi, or micro-organisms that live on dead or decomposing matter. Some may more accurately be called myco-heterotrophs.

Xerophytes: These are plants that grow in the desert.

Detrivores: consumers that feed at every trophic level, obtaining their energy and nutrients by eating dead organic matter. Typical detritivorous animals include millipedes, woodlice, dung flies, slugs, many terrestrial worms, sea stars, sea cucumbers, fiddler crabs, etc.

Ecosystem ecology: studies â&#x20AC;&#x2DC;the flow of energy and materials through organisms and the physical environmentâ&#x20AC;?. The study of ecosystems can cover 10 orders of magnitude, from the surface layers of rocks to the surface of the planet.

Ecological pyramid: a model that shows the loss of energy from one trophic level to another often called an ecological pyramid Ecotone: A region of transition between two biological communities.

Keystone species: species (eg, salmon) that can greatly affect population numbers and the health of an ecosystem.

Epharmony: the immediate acquirement by an organism of a morphological or physiological alteration that enables it to exist in an altered environment.

Nutrient cycle: the way nutrients are cycled in the biosphere, the continuous flows (exchanges) of nutrients in and out of stores.

Section:5 - Urban Design Hippodamus (5thcentury BC) of Miletus was a Greek architect who introduced order and regularity into the planning of cities, which were intricate and confusing. For Pericles, he planned the arrangement of the harbor-town Peiraeus at Athens. When the Athenians founded Thurii in Italy, he accompanied the colony as architect. Later, in 408 B.C., he superintended the building of the new city of Rhodes. His schemes consisted of series of broad, straight streets, intersecting one another at right angles.

Haussmann (1809-1891) was a French civic planner who is associated with the rebuilding of Paris. He was born in that city of a Protestant family of German descent. Commissioned by Napoleon III to instigate a program of planning reforms in Paris, Haussmann laid out the Bois de Boulogne, and made extensive improvements in the smaller parks. The gardens of the Luxembourg Palace were cut down to allow of the formation of new streets, and the Boulevard de Sebastopol, the southern half of which is now the Boulevard St. Michel, was built through a populous district. Additional, sweeping changes made wide “boulevards” of previously narrow streets. A new water supply, a gigantic system of sewers, new bridges, the opera and other public buildings, and the inclusion of outlying districts were among the new Haussmann’s achievements. His bold handling of the public funds called forth Jules Ferry’s indictment, in 1867.

Ebenezer Howard (1850-1928) came to America from England at the age of 21. He settled in Nebraska, and soon discovered that he was not meant to be a farmer. He moved to Chicago and worked as a reporter for the courts and newspapers. By 1876, he was back in England, where he found a job with a firm producing the official Parliamentary reports, and he spent the rest of his life in this occupation.

Howard read widely and thought deeply about social issues, and one result was his book To‐Morrow: A Peaceful Path to Real Reform (1898), reprinted in 1902 as Garden Cities of To‐Morrow. This book called for the creation of new suburban towns of limited size, planned in advance, and surrounded by a permanent belt of agricultural land. Many suburbs were modeled after Howard’s “Garden Cities.” He believed they were the perfect blend of city and nature.

His ideas attracted enough attention and financial backing to begin Letchworth, a garden city in suburban London. A second garden city, Welwyn, was started after World War I. Their success led the British government to develop New Towns after World War II. This movement produced more than 30 communities, most significantly perhaps Milton Keynes. Howard’s ideas inspired other planners such as Frederick Law Olmsted II and Clarence Perry.

Le Corbusier(1887-1965) was without doubt the most influential, most admired, and most maligned architect of the twentieth century. Through his writing and his buildings, he is the main player in the Modernist story, his visions of homes and cities as innovative as they are influential. Many of his ideas on urban living became the blueprint for post-war reconstruction, and the many failures of his would-be imitators led to Le Corbusier being blamed for the problems of western cities in the 1960s and 1970s.

In the 1920s and 1930s, Le Corbusier’s most significant work was in urban planning. In such published plans as La Ville Contemporaine (1922), the Plan Voisin de Paris (1925), and the several Villes Radieuses (1930-36). He advanced ideas dramatically different from the comfortable, low-rise communities proposed by earlier garden city planners. During this 20-year span, he also built many villas and several small apartment complexes and office buildings.

Lewis Mumford‘s (1895-1988) long life was marked by work in urban planning, history, and political and social commentary. He viewed architectural congestion as a dehumanizing influence and was instrumental in founding the Regional Planning Association of America in 1923.

Different Types of Sampling Simple random sampling -In simple random sampling, the members of the sample are selected randomly and purely by chance. As every member has an equal chance of being selected in the sample, random selection of members does not affect the quality of the sample.

Systematic sampling -In systematic sampling, a member occurring after a fixed interval is selected. The member occurring after fixed interval is known as Kth element. For EX, if a research wants to select member occurring after every ten members, the Kth element become 10th element. It means for selecting a sample from 100 members will be as follows: Sample (10, 20, 30, 40, 50, 60, 70, 80, 90, 100) In cluster sampling, various segments of a population are treated as clusters and members from each cluster are selected randomly. In stratified sampling, the researcher divides the population into homogeneous subgroups on the basis of similar characteristics e.g. age, sex, profession, religion and so on.

On the other hand, in cluster sampling, the does not divide the population into sub-groups or cluster but randomly select from already existing or naturally occurring sub-groups.

In multi-stage sampling, each cluster of the sample is further divided into smaller clusters and members are selected from each smaller cluster randomly. It is called a multi-stage sampling as it involves many stages.

Purposive Sampling or judgmental sampling-It is a type of sampling where the members for a sample are selected according to the purpose of the study.

For example, if a researcher wants to study the impact of drugs abuse on health. Every member of the society is not the best respondent for this study. Only the drug addicts can be the best respondents for this study.

Stopping sight distance (SSD): SSD Is the sight distance which is necessary for a driver to stop a vehicle from the design speed to the 0 speed without any collision with the obstruction on the road. It is also known as the absolute minimum sight distance so this much sight distance is provided at all the cross section of the road.

Over-Taking Sight Distance (OSD): OSD is the sight distance which is necessary for a vehicle running at the design speed to overtake a slower moving vehicle without collision with the vehicles coming from the opposite direction. Generally, it is not possible to provide the OSD at every crass section of the road so, it is provided after a stretch of the road.

Super- Elevation: The outer edge of the road with respect to the inner edge of the road is raised in case of the horizontal curves, this is called super-elevation. Super- elevation is necessary to counter-act the centrifugal force due to the radius of the curve and speed of the vehicle.

Time mean speed means the speeds of vehicles passing a point is arithmetic mean of speeds of vehicles passing a point.

Space mean speed is the harmonic mean of speeds passing a point during a period of time. It also equals the average speeds over a length of roadway.

Note that the time mean speed is average speed past a point as distinct from space mean speed which is average speed along a length.

Time headway is the difference between the time when the front of a vehicle arrives at a point on the highway and the time the front of the next vehicle arrives at the same point (in seconds) Average Time Headway Space Space headway is the difference in position between the front of a vehicle and the front of the next vehicle.

2.Building Services HVAC System

Air changes per hour-The hourly ventilation rate divided by the volume of a space. For perfectly mixed air or laminar flow spaces, this is equal to the number of times per hour that the volume the space is exchanged by mechanical and natural ventilation. Also called air change rate or air exchange rate.

Abbreviated as ACH or ac/hr.

Air conditioner-An appliance, system, or mechanism designed to dehumidify and extract heat from an area. Usually this term is reserved for smaller self-contained units such as a residential system.

Air handling unit-A central unit consisting of a blower, heating and cooling elements, filter racks or chamber, dampers, humidifier, and other central equipment in direct contact with the airflow. This does not include the ductwork through the building. Abbreviated as AH or AHU. Chiller-A device that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle.

This cooled liquid flows through pipes in a building and passes through coils in air handlers, fan-coil units, or other systems, cooling and usually dehumidifying the air in the building. Chillers are of two types; aircooled or water-cooled. Air-cooled chillers are usually outside and consist of condenser coils cooled by fan-driven air. Water-cooled chillers are usually inside a building, and heat from these chillers is carried by recirculating water to a heat sink such as an outdoor cooling tower.

Condenser-A component in the basic refrigeration cycle that ejects or removes heat from the system. The condenser is the hot side of an air conditioner or heat pump. Condensers are heat exchangers, and can transfer heat to air or to an intermediate fluid (such as water or an aqueous solution of ethylene glycol) to carry heat to a distant sink, such as ground (earth sink), a body of water, or air (as with cooling towers).

Damper-A plate or gate placed in a duct to control air flow by increasing friction in the duct.

Fan Coil Unit-A small terminal unit that is often composed of only a blower and a heating and/or cooling coil, as is often used in hotels, condominiums, or apartments. Abbreviated as FCU. 589 This book is a copyright of Yash Kotgirwar and Zakkaullah Bader and licensed to student for personal GATE preparation.
