• Air-conditioning and ventilating systems
circulating air to more than one floor or fire
area shall be provided with dampers
designed to close automatically in case of
fire and thereby preventing spread of fire or
smoke.
• Separate air handling units for each floor
shall be provided to avoid the hazards
arising from spread of fire and smoke
through air conditioning ducts.
BASEMENT SMOKE VENTILATION
• Fire in a basement is very different to that above ground
for two fundamental reasons.
• Firstly, true basements are enclosed, with no windows or
means of ventilation, this condition allows for rapid heat
build up with nowhere for the heat to dissipate to, other
than internal openings within the basement.
• Within a basement, the most common internal vertical
opening into which smoke will want to dissipate is the
stairs, which are likely to be required and possibly used
for means of escape.
• On the basis that increased heat build up is the primary
concern with basement fires, it should be no surprise
that the critical fire safety requirement placed on a
basement is ventilation, i.e. a means of allowing the
smoke and heat to pass from the basement area to
external, thus reducing the risk associated with the
conditions described above.
• There are two common methods of reducing the smoke /
heat build up within basements, namely natural and
mechanical ventilation, although it is noted there are
variations thereof.
BASEMENTS REQUIRING VENTILATION
The current Building Regulations in England and Wales
require that a smoke control system to be provided for
any basement storey that has:

• A floor area of more than 200m2 and;

• A floor more than 3m below the adjacent ground level.

• All basement car parks, regardless of the size.

NATURAL VENTILATION:
• Naturally ventilated car parks require a minimum 1/40th (2.5%)
of the net floor area of the basement car park in openings linked
directly to the atmosphere, with at least 50% of the opening
being split between two opposing walls.
• This allows a good flow across the vents and ensures that the
system is not undermined by wind pressure acting on one side of
the building, as a positive pressure to one face, should assume a
negative pressure to the opposing

MECHANICAL VENTILATION:
• The minimum rate for a mechanically ventilated car park is 10 air
changes per hour under fire conditions.
• The system should be independent of any other ventilating
system (other than any system providing normal ventilation to
the car park). Other design considerations include:
• The system should be designed to run in two parts, each part
capable of extracting 50% of the rates set out in above and
designed so that each part may operate singly or simultaneously.

• Exhaust Fan With Shutter Provide Quiet Air Ventilation and
Circulation For Applications Including Residential, Commercial,
Industrial, and more.
• Adjustable shutters regulate ventilation flow, prevent external air
entry and deter intrusion.
• Shutters are an accessory item used to seal off backdrafts when the
fan is not operating. Air flows to a fan from inside the building and
exits the fan in a spinning pattern.
• The most common type of shutter used with agricultural exhaust
fans is a vertical vane in either aluminum or plastic
 LANDSCAPING AND GREENERY:
• A minimum 2 m wide green planting strip in the
periphery on all sides within the setbacks are
required to be developed and maintained.
• An organized open space of at least 10 % of total
site area shall be maintained and utilized as
greenery over and above the mandatory around
setbacks. This could be part of the interior open
space or be in one or more pockets.
• Trees shall be planted within the periphery of the
site at the rate of 1 tree per 100 sq m of site area.

EXIT FACILITIES

2000MM
exits as remote from each other as practicable.
• Exits shall be provided for waiting spaces on the basis of
one person for each 0.3 M2 of waiting space area. At
least half the required means of exits shall lead directly
outdoors or through exit ways completely separated
from exits serving other parts of the building.
SEATING
• Clear aisles not less than 1.2min width shall be formed

SEATING UNITS
BANQUET HALLS
• A Banquet hall is an area in a hotel or a building where most
of the events like wedding, reception or parties take place.
• These banquet halls are designed in a way which makes the
place luxurious and attracts customers and the attention of
the guests.
• This is very important that AMBIENCE will have the
prominent role as that will change the complete outlook of the
even and hence is very important.
• People need to look at the banquet hall designs layout, as
that will help you to get better feel for your event.
• It is very important the promoters take the help of
professional for deciding the banquet hall design concept.
• This should be done in the right way and keeping in mind the
banquet hall design requirements.
• And lighting also had a important role, while designing the
banquet halls.
• The lighting should not be bright and powerful, should be
smooth which gives the banquet hall good ambience.
REQUIREMENTS
• There are different types of banquet halls with different
shapes.
• So there is no perfect size to it as these halls are used
for different events.
• But the size of the hall should be definitely above 1500
sq.ft.( 139 sqmts).
• Normally a guest requires around 10-12 sq.ft.( 0.9 –
1.11sqmts) to accommodate table and chair. The seating
arrangement should be according to the area of the hall.
• If the hall is smaller in size then fewer seats should be
accommodated, to avoid congestion in the banquet hall.
• There must be ample space between the stage or the
dance floor and make sure that to take care of the
banquet hall exterior design,
• Where it is more important, and will decide the place
looks and feels like.
TYPES OF BANQUET HALLS
•Banquet Round Table Setup.
•Crescent Round Table Setup.
•Round Table Classroom Style Setup.
•Conference / Boardroom Style Setup.
•Auditorium Style / Theatre Style Setup.
•Open-Ended / U-Shaped Table Setup.
•Herringbone / Fishbone Banquet Setup.
•Star or Starfish Style Setup.
BANQUET ROUND TABLE SETUP
• In the banquet round table setup plan, only round tables are
used with various sizes. This style is best suited for meal
functions where the guests are required to sit and dine unlike
in the standing buffet. Hotels use round tables of different
sizes to accommodate the guests.
• The smaller the round table used, the more the space
required, as every addition of a table calls for more area for
gangways. To avoid losing many areas in the gangway, it is
better to go for round tables of larger dimensions.

These are the dimensions of round tables and their seating

capacities that are commonly used:

•1.52m dia accommodates 6 to 8 guests

•1.67m dia accommodates 8 to 10 guests
•1.8m dia accommodates 10 to 12 guests
•Most banquet halls use tables of 1.8m
CRESCENT ROUND TABLE SETUP
• In this type of table setup plan, the guests are
seated at one side of the round table to
observe the preparation.
• The guests will be occupying half of the
circumstance of the table which obviously
means that this type of plan will be requiring
double the area of round table arrangement.
• The benchmark is 2.4sqmts(26 sq. ft.) per
person.
• To accommodate 200 people, the minimum
area required is 480 sqmts.
• Ideal for meal-centered meetings and
banquets encouraging business and
socialization for any size group
• No back is facing the speaker
• Less elbow room than a cluster
ROUND TABLE CLASSROOM STYLE SETUP
• The seating arrangement in this style is similar to
the classroom with tables to write and chairs.
• This type of plan is recommended for the
workshop, seminars, lectures, etc. in which the
participants are required to take hints or study the
handouts.
• A table of 1.8m or 2.4m long and 0.4m or 0.7m
wide is generally used.
• The chairs used maybe with armrest or without
armrest.
• The benchmark calculation for this style of
arrangement is 1.3 to 1.4 sqmts per person if
0.45m wide tables are used and 1.4 to 1.6 sqmts
0.7m wide tables are used.
CONFERENCE / BOARDROOM STYLE SETUP
• It is the plan with a rectangle table and chairs
around.
• It is an effective banquet table setup style for small
groups for discussion and presentation.
• In this plan, guests sit around a rectangular table
and observe the presentation and interact.
• The ideal plan for the board of directors meet,
managers meet, etc. where top management is
involved.
• It suffers from some drawbacks.
• If the group is larger, this style of table plan may
keep the participants too far apart for effective
interaction or communication.
• The front would have to turn their chairs to see the
screen or watch the speaker.
• The area allowance per person is 1.9 to 2.3 sqmts.
AUDITORIUM STYLE / THEATRE STYLE SETUP
• Only chairs are used in this style of banquet setup.
• Chairs are arranged in rows, such as in theatre
leaving adequate legroom between the rows of
chairs.
• Most people can be accommodated in this plan. It
is allowance per person is 0.7 to 0.83 sqmts.
•Seats are in rows facing the stage area, no tables.
•Benefits:
• Perfect for shorter presentations, seminars,
lectures and Q&A’s
• Best suited for presentations that require
more elaborate A/V technology
•Best Meeting Uses:
• Teaching/Training
• Lecture/Presentation
• Team Building
• Executive Presentation
• Seminar
• Workshop
OPEN-ENDED / U-SHAPED TABLE SETUP
• This banquet table setting plan is made
by joining the tables to make
a ‘U’ shape and the chairs are placed
along the outer side of the table.
• It is suitable for intense meetings that
require interaction.
• The presentation source is at the front
of the U-shape or opened end.
• The limitation in this style is that the
participants can be spread too far for
effective interaction in a large U-shaped
plan.
• The area allowance for the ‘U’ shaped
plan per person is 2.7 to 2.9 sqmts.
HERRINGBONE / FISHBONE BANQUET SETUP
• This banquet-style setup is similar to a
classroom-style set up with the tables and
chairs arranged at a slight angle.
• The chairs may be placed on either one
side or both sides of the tables.
• This type of table arrangement is ideal for
making better use of space in small rooms.
• The area allowance per person in this type
of plan is difficult to ascertain because the
angles of the setups vary.
• The area allowance, however, is less than
the straight setups.
MEETING ROOMS
• Meeting rooms are typically used for
interactive processes, be it quick
conversations or intensive brainstorms.
• It is suitable for both formal and informal
interactions.
• A meeting room is a space usually set
aside for people to get together, often
informally to hold meetings, for issues to be
discussed, priorities set and decisions
made.

be permitted but In no case greater than 1 in 8.
TOILET STANDARDS

For a capacity of 200 members

For males – 2 water closets, 7 urinal, one ablution tap, one wash basin
For females – 2 water closets, one ablution tap, one wash basins
SEWAGE DISPOSAL
SOIL DISPOSAL SHALL BE DONE THROUGH SEPTIC TANKS OF DIFFERENT SIZES OR BY
STABILIZATION PONDS OR BY
ANY OTHER TREATMENT METHODS SUCH AS:
• EXTENDED AERATION ACTIVATED PROCESS
• SEQUENTIAL BATCH PROCESS
• FLUIDIZED BIO-REACTORS
• MEMBRANE BIO-REACTOR
• SUBMERGED AEROBIC FIXED FILM
• ROTATING BIOLOGICAL CONTACTOR
• ELECTROLYTE PROCESS

EXTENDED AERATION ACTIVATED

PROCESS:
Works by providing ideal conditions for aerobic bacteria
and other micro-organisms; these micro-organisms then
decompose the biological contaminants in the raw
sewage.

This process operates under the following theory: Waste

in domestic wastewater is generally organic, and aerobic
microorganisms in the presence of oxygen can use the
organic material as their food source.
ELECTROLYTE PROCESS:
• Electrolysis is a technique involving the passage of electricity
through the effluent.
• The electrical current destabilizes dissolved colloidal particles
and alters the charge on suspended particles permitting
purification of water.
• Does not generate greenhouse gases.
• Emits low carbon.
• Conserves more water due to better quality treatment.
• Generates less sludge with better dewatering.
• Less maintenance and High performance to cost ratio.

RAINWATER HARVESTING:
Two major systems that are ideal for urban and semi-urban developed areas are:
a) Artificial ground water recharge.
b) Roof top rainwater harvesting.
ARTIFICIAL GROUND WATER
RECHARGE:
The main objectives achieved may be:
• Enhancement of sustainable yield in areas
where over development and depletion of the
aquifers.
• Conservation and storage of excess surface
water in the aquifers.
• Improve the quality of the existing groundwater
through dilution.
• Remove bacteriological and suspended
impurities during the surface water transition
within the subsoil.
• Maintain the natural balance of the ground
water and its usage.
In planning and designing the ground water
recharge structures, following should be taken into
consideration:
• Annual rainfall.
• Peak intensity and duration of each storm.
• Type of soil and subsoil conditions and their
permeability factor.
• Ground slopes and run off which cannot be
caught.
• Location of recharge structures and its overflow
outfall.
• Rainwater measuring devices for finding the
flow of water in the system.
ROOF TOP RAINWATER HARVESTING:
In a well-planned building complex, a system should be laid out so that
the runoff is collected in underground or above ground water storage
tank, pretreated, stored, and used for non-potable purposes.
CARE TO BE TAKEN IN RAINWATER
HARVESTING:
• No sewage or wastewater should be admitted into the system.
• No wastewater from areas likely to have oil, grease or other
pollutants should be connected to the system.
• Each structure/well shall have an inlet
chamber with a silt trap to prevent any silt
from finding its way into the subsoil water.
• The wells should be terminated at least
5 m above the natural static subsoil
water to prevent contamination
hazards.
• No recharge structure or a well shall be
used for drawing water for any purpose.
SIPHONIC DRAINAGE SYSTEM:
It is an installation generally used for special situations such
as roofs with large spans for structures like hangars, airport
terminals, stadia and industrial sheds, where the number
of down pipes has to be limited.
These are designed for full flow of pipes and the roof
outlets are different from conventional ones.

OTHER METHODS OF RAINWATER

HARVESTING:
• Creation of artificial reservoirs.
• Water balancing methods- optimum utilization of water
from various sources of water.
