ABSTRACT Varanasi is one of the oldest living cities in the world-famous for its production of silks and brocades with gold and silver threadwork of northern India for several thousand years and is closely associated with the river Ganges.

“Ekaya Banaras – Cultural & Commercial Center, Varanasi” is undertaken to establish the need to set up a cultural and commercial center in Varanasi due to the maximum number of citizens involved in manufacturing, trade, and commerce. Establishing a local center for trade and exhibition of local products would make all kinds of locally made specialties readily available to the buyers. The spatial programs have been subdivided into a museum, auditorium, retail shops, offices, skill development center, exhibition area to house the local demands and amenities focused on providing an integrated platform for the promotion of handloom, handicrafts, and carpet sector of Varanasi.

The center would provide resources to meet the needs of individuals and groups for exploration of new techniques and enhancement of skills in the manufacturing of products. The project objective revolves around promotion and enhancement of rich traditions of the city along with the provision of a platform to showcase the same, linking handloom & handicrafts products’ promotion with domestic & international tourism, trade facilitation, export, and one-stop-shop to domestic enterprise and foreign buyers as well as to create a building which could be a landmark in the city/state to attract tourists and local visitors.

The design objectives have their prime focus on providing different ambiances and spatial environments to maintain the mixed-use objective of the building such as exhibiting, selling, shopping, and recreational activities within a single roof. It also includes creating spaces, indoor and outdoor that would impact by making a memorable experience. Along with these aspects, the design would also formulate spaces that would be connected and yet would be distinct.

Varanasi experiences a humid subtropical climate with large variations between summer and winter temperatures. The temperature ranges between 22 and 46 °C (72 and 115 °F) in the summers.

Figure 12: Climatic Data for Varanasi, Uttar Pradesh

Site opportunities & challenges: •

Proposal by Government of India.

•

The site also contains a good number of trees and vegetation.

•

The site is a bit secluded on its own which leads to the increase in the quality of activities like Meditation, Yoga, Music, etc.

•

The presence of spaces like gardens, playgrounds, temples, etc. leads to the availability of breathing space for the building.

•

In this area, water levels are always high even in the summer season. This is due to the local source of water. The subsoil at the upper level is silty clay (Alluvial soil).

Due to the presence of high-water level in all the season. The subsoil at the upper level is loose.

1.8 SWOT Analysis: STRENGTHS: a.

Integrated marketing platform: ▪ TFC&CM is an iconic structure designed as an integrated marketing platform for handloom, handicraft, and carpet sector players in the region, ▪ It has one of the largest capacity convention centers in the region, and will play a major role in facilitating the Varanasi region for its MICE activities,

b.

Centre of Tourism and Culture: ▪

The region is a major attraction for national and international tourists with 84 Ghats, 3000 shrines, temples, among Sarnath, Kashi Vishwanath temples, Aarti at Ganga, 720 festivities celebrated annually, prominent center for Hindustani Classical Gharana, etc.

▪

Varanasi Cantonment station, Varanasi City Railway Station, and Mughalsarai Railway Station.

WEAKNESSES: The convention activities in Varanasi are at a nascent stage, however, due to the lack of such facilities, the sector is not fully captured yet.

Opportunities: a. Business Development Opportunities ▪ Immense potential for the tapping of nascent markets of conventions, exhibitions, business meets, and conferences, etc.

ARCHITECTURAL VOCABULORY The plaza intends to bring back to life the traditional historical elements through means of modern interpretation, repetition, and symmetry, having played an essential part in the designing and conceptualizing of the structure. A distinctive jaali screen made in Aluminum and brick that wraps the building adapts motifs from traditional Varanasi architecture.

Study of the vernacular in an effort to find ways to treat the riverfront: Ghats were the natural answer since they lend themselves to stabilizing the river-edge while providing an interface for human engagement with the river. Design of the ghats combined the use of several typologies of platform to account for diverse functions smaller ones for daily rituals, and large performance stages for events.

The mixed use precinct will cater to 1500 - 2000 tourits per day as well as visitors coming for recreational and community activities.

Inspired by the cultural activities happening at Ghats of Varanasi and a separate commercial retail shops for the tourists and visitors.

SITE CHALLENGES & OPPORTUNITIES:

EXISTING SCENERIO: Recreational As observed, the existing height in the area does not exceed 30m on the North and North - western sides of the site and 12m on the South and South - western sides This variation is due to the new development taking place i.e. high rise residential apartments.

Varanasi is well connected by railways with broad gauge. • Type : Institutional, Commercial & There are three rail lines entering to the city from Lucknow, (Mixed-use) Bhadoi and Allahabad and is diverted in two lines to • F.A.R. : 2.0 Gorakhpur and Mughal Sarai.

• Frontage : 50M • Setbacks: Front : 15M; Back & Rear-9M • Parking : for 100 SQ.M 2 - E.C.U • Tentative Built-Up Area : 40, 000 SQ.M • Connecting Roads : Hockey Stadium Road – 24M wide • Location : Bada Lalpur, Chandmari, Varanasi, U.P.

The city lies on Delhi-Kolkata rail route of North Eastern Railways, which is the broad gauge. A rail line connects the town with Sarnath, located 13 Km north-east of the city.

Sarnath is from where Gautama Buddha first taught the Dharma and where the Buddhist Sangha came into existence through the enlightenment of Kondanna. The other cities having good connectivity through railways are Patna, Guwahati, Chennai, Mumbai, Gwalior, Meerut, Lucknow, Kanpur and Allahabad.

INTRA CITY MOVEMENT:

The site is situated in the middle of the varying heights. Hence, the proposed project should follow the existing gradual skyline i.e. height should not go above 30m. The proposed Cultural & Commercial Center should be designed having a similar character so that it blends well with it surroundings.

• •

• The movement within the city is a mix of Taxis Autos, cycle rickshaws, private vehicles, and walk (by foot is the only way to see the waterfront and the Ghats) and 25% of the citizens • use personal vehicle to communte around the city.

Also, the building demands to be designed as a landmark.

Hence, the height of the building has been increased as compared to the ones on the South.

This makes it prominently visible from the main arterial road The site is well connected to all prominent regions i.e. the Urban Extension Road through roadways and public transport network but lacks comfortable pedestrian networks.

This Trans-Varuna region of Varanasi is needs to be developed at a good pace as people living in the Heritage Zone of Varanasi are now shifting towards this area.

Site is flanked by residential area/built-up areas of Bada Lalpur and direct connected highway leading towards Lal Bahadur Shahstri Airport.

No Retail outlets and public gathering plazas in the nearby area not available.

Ekaya Banaras - Commercial & Cultural Center Cultural & Commercial Center

2 SITE CONTEXT 2.1 CLIMATE ANALYSIS Varanasi experiences a humid subtropical climate (with large variations between summer and winter temperatures. The dry summer starts in April and lasts until June, followed by the monsoon season from July to October. The temperature ranges between 22 and 46 °C (72 and 115 °F) in the summers. Winters in Varanasi see very large diurnal variations, with warm days and downright cold nights. Cold waves from the Himalayan region cause temperatures to dip across the city in the winter from December to February and temperatures below 5 °C (41 °F) are not uncommon. The average annual rainfall is 1,110 mm (44 in). Fog is common in the winters, while hot dry winds, called loo, blow in the summers. In recent years, the water level of the Ganges has decreased significantly; upstream dams, unregulated water extraction, and dwindling glacial sources due to global warming may be to blame.

Temperature:

The hot season lasts for 2.6 months, from April 4 to June 23, with an average daily high temperature above 99°F. The hottest day of the year is May 23, with an average high of 106°F and a low of 80°F. The cool season lasts for 2.1 months, from December 6 to February 10, with an average daily high temperature below 78°F. The coldest day of the year is January 10, with an average low of 49°F and a high of 72°F.

Humidity: Varanasi experiences extreme seasonal variation in the perceived humidity.

The muggier period of the year lasts for 6.1 months, from May 5 to November 8, during which time the comfort level is muggy, oppressive, or miserable at least 26% of the time. The muggiest day of the year is August 9, with muggy conditions 100% of the time.

The least muggy day of the year is January 11, with muggy conditions 2% of the time.

2.3 INFERENCE AND DESIGN RECOMMENDATIONS Since the weather conditions in Varanasi are very harsh specifically during the summers in April to July, an effective and energy-efficient centralized air conditioning & VRV system is required while keeping in mind the pollution level in the city.

Climate: Varanasi experiences a humid subtropical climate with large variations between summer and winter temperatures. The temperature ranges between 22 and 46 °C (72 and 115 °F) in the summers.

Site opportunities & challenges: Proposal by Government of India.

The site also contains a good number of trees and vegetation.

The site is a bit secluded on its own which leads to the increase in the quality of activities like Meditation, Yoga, Music, etc.

The presence of spaces like gardens, playgrounds, temples, etc. leads to the availability of breathing space for the building.

In this area, water levels are always high even in the summer season. This is due to the local source of water. The subsoil at the upper level is silty clay (Alluvial soil). Due to the presence of high-water level in all the season. The subsoil at the upper level is loose.

4.2 INFERENCE 1. All the spaces are centrally connected to the main area that is the concourse space which is approximately 45,000 cubic meters.

2. All spaces have large volumes and heat gain and hence a centralized system will be the most suitable system wherein the Main Building Block in ZONE 1 will have FCUs in all the galleries connected to the AHUs near the services.

3. The concourse space i.e., ZONE 2, 3, and 4 will have a central system where the fresh air will be facilitated through the ceiling and the return air will also be thrown out of the ceiling.

4. The hotel floors i.e., ZONE 5 and 6 will have an FCU system for the hotel rooms.

Hence, a centralized air conditioning system is the most suitable system.

4.3 CALCULATION FOR DUCTS SIZE AND AIR DIFFUSERS The calculation for the number of diffusers Air flow (Q) = (Volume X Air change per hour) / 3600sec = [1800 X 5 X 8 (air change per hour for public spaces)] / 3600 = 20 m3/s 2 AHUs are installed.

So, Q = 10 m3/s per AHU Recommended maximum air velocity for silent operation is 4m/sec. (ASHRAE) Cross Sectional Area = Q (Flow) X V (Velocity) = (10 X 106)/ 4 = 2.5 X 106 m2 Size of diffusers taken as 480mm X 480mm.

No of air diffusers = Cross-sectional Area of duct / Area of diffusers

79

Ekaya Banaras - Commercial & Cultural Center Cultural & Commercial Center

4.4 CALCULATION FOR DUCT SIZE The Aspect Ratio is 2:1 Hence, 2b = a (where a = width of duct, b = depth of duct) Cross-sectional area (known from the above calculation) = a X b 2.5 X 106 = 2b X b = 1118mm a = 2236mm Hence, values of a and b will be derived.

For calculation of duct reduction, the Area of the air diffuser is subtracted from the cross-sectional area of the duct.

Area of d2 = Area of d1 - Area of air diffuser (0.16 X 106) Area of d2 = a x b Area of d2 = 2b x b b = whole root of (Area of d2 / 2) a = 2b Hence, the size of the new duct will be derived.

5.1 INTRODUCTION OF SYSTEM Mechanical services work involves the construction, installation, replacement, repair, alteration, maintenance, testing, or commissioning of a mechanical heating or cooling system in commercial and residential buildings, for example, air conditioning, refrigeration, and air handling systems. Heating, ventilation, and air conditioning (HVAC) are the technology of indoor and vehicular environmental comfort. It involves the process of exchanging or replacing air in any place to provide high-quality indoor air, which involves temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, etc. from the air. Building cooling load components are; direct solar radiation, transmission load, ventilation/infiltration load, and internal load. Calculating all these loads individually and adding them up gives the estimate of the total cooling load. The load, thus calculated, constitutes the total sensible load.

5.2.1 CENTRALISED CHILLED WATER SYSTEM: A central HVAC system serves one or more thermal zones, and its major equipment is located outside of the served zone, whether inside, on top, or adjacent to the building.

The thermal energy transfer system can be air, water, or both. Chilled water systems provide cooling to a building by using chilled water to absorb heat from the building’s spaces. A chilled water system refrigeration cycle works by removing heat from chilled water in the evaporator of the chiller. The compressor is what drives the entire process.

In the condenser of the chiller, the heat is transferred to the condenser water, or directly to the outside air.

CHILLED WATER LOOP: The chilled water loop consists of pipes and pumps that move chilled water around a building. A chilled water pump pushes chilled water through the chiller and the chilled water line around the building. The chilled water supply is pumped through the chiller and to the building’s various air conditioning units such as air handling units (AHUs) and fan coil units (FCUs):

82

Ekaya Banaras - Commercial & Cultural Center Cultural & Commercial Center

1.

In the AHUs and FCUs, the chilled water is passed through a heat exchanging coil to reduce the temperature of the coil.

2.

While the heat exchanging coil is cooled by the chilled water, a fan blows air through the coil to provide cold air to the building’s space.

3.

After exiting the heat exchanging coil, the chilled water return (CHWR) returns to the chiller, where it is cooled again, and the process repeat

WATER-COOLED CHILLER SYSTEM: Water-cooled chillers are almost always located inside of a building.

They work almost the same way as aircooled chillers. The difference is that they remove heat from chilled water by exhausting the heat to a second, isolated water line called the condenser water line.

The condenser water flows through the chiller and picks up heat. The condenser water then returns to the cooling tower. The cooling tower is almost always located outside of the building and removes heat from the condenser water by evaporating some of the condenser water into the atmosphere. As some of the condenser water evaporates, heat is removed from the condenser water, and the cool condenser water flows back to the chiller. This process is then repeated all over again.



For fresh air used centralized treated fresh air unit for each zone.



The VRV system designed is cooling and heating type to cater to summer and winter load efficiently.

5.3 SYSTEM REQUIREMENTS 

5.4 CRITERIA OF SELECTION  Auditoriums, exhibitions, and convention halls are characterized by high people density value and high activity level. They have high occupant cooling loads and requirements of outside air.  The halls also require cooling for only a few hours and there are diverse requirements of cooling. Variety of loads depending upon the activity. 

Water-cooled chiller systems are very energy efficient. Due to their complexity and many different parts, they are often more expensive to install and maintain. For this

84

Ekaya Banaras - Commercial & Cultural Center Cultural & Commercial Center

reason, they are usually only found in large buildings. This is because the energy savings outweigh the cost of installing and maintaining the system.

The total load of the center is > 200 tons so a water-cooled chilled water system is an efficient choice.

Glossary

GLOSSARY: Atrium - An atrium is a large open space located within a building. It is often used to light a central circulation or public area by daylight admitted through a glass roof or wall. Atria provide some daylight to adjacent working areas, but the amount is often small and does not penetrate very far. The main function of an atrium is to provide a visual experience and a degree of contact with the outside for people in the working areas.

Average Daylight Factor (ADF) - is the “ratio of total daylight flux incident on a reference area to the total area of the reference area, expressed as a percentage of outdoor illuminance on a horizontal plane due to an unobstructed hemisphere of the sky of assumed or known luminance e-distribution” [1]. ADF can be calculated using the following equation [2]: ADF=TAwθ M/{A(1–R²)} T: the glass transmittance; Aw: the effective window area (excluding the frames); θ: the visible sky angle; R: the average reflectance of the room, M: the maintenance factor; A: the total surface area of the room in m² (floor + ceiling +walls including the windows).

Comfort range - A range with a minimum and maximum value within which comfort is assumed.

Daylight autonomy (DA) - The DA is defined as the percentage of time – over a year – for which daylight can provide a specific intensity of light (e.g. 500 lux) in interiors.

Daylight factor (DF) - The DF expresses – as a percentage – the amount of daylight available indoors compared to the amount of unobstructed daylight available outdoors under standard CIE sky conditions.

Glare - Glare is a sensation caused by an uncomfortably bright light source or reflection in the field of view that can cause annoyance, discomfort, or loss in performance and visibility.

Illuminance - Illuminance is the measure of the amount of light received on a surface.

It is typically expressed in lux.

Light Tubes - Another type of device used is the light tube, also called a tubular daylighting device (TDD), which is placed into a roof and admits light to a focused area of the interior. These somewhat resemble recessed ceiling light fixtures. They do not allow as much heat transfer as skylights because they have less surface area.

Luminance - Luminance is the measure of the amount of light reflected or emitted from a surface. It is typically expressed in cd/m².

Lux (lx) - Unit of illuminance. One lux is one lumen per square meter (lm/m²).

Sawtooth roof - Sawtooth roofs have vertical roof glass facing away from the equal or side of the building to capture diffused light (not harsh direct equator-side solar gain). The angled portion of the glass support structure is opaque and well insulated with a cool roof and radiant barrier.

Seasonal Affective Disorder (SAD) - Also called winter depression. A mood disorder caused by low light levels in winter.

Sick Building Syndrome (SBS) - Term sometimes used to describe situations in which building occupants experience acute health and/or comfort effects that appear to be linked to time spent in a particular building, but where no specific illness or cause can be identified.

Visible transmittance (τv) - The amount of daylight coming through a window is referred to as the visible transmittance (τv) and is dependent on the composition of the window pane.

Window system - A window system is a window and its accessories as a combined unit. Accessories are shading devices or other devices that change the parameters of the window as a whole.
