Sustainable building design

1. SUBTOPICS

2. FUNCTIONAL ELEMENTS
FIRE PROTECTION
• According to National building code of India- Fire
protection is the study and practice of mitigating the
unwanted effects of fires.
• Basic Fire safe design, various smoke control practices
and fire proofing has been taken into consideration in
further slides

3. FIRE SAFE
DESIGN
•Fire resistive
construction
•Compartmentation
•Provision for fire
fighting

4. SMOKE
CONTROL

5. FIRE PROOFING
• Sprayed-on applications of mineral fiber or
cementitious materials
• Encapsulation of structural steel members with
concrete
• Floor or roof, ceiling and Wall assemblies
• Wood products can be treated or coated to improve
behavior in fire

6. WATER PROOFING/ DAMP PROOFING
• Water Proofing- It is used to prevent water penetration
under hydrostatic pressure to the surfaces of
components, such as structural steel and through
assemblies such as exterior masonry walls, foundation
walls, roofs.
• Damp Proofing- It means protection against the passage
of water in small quantities and not under pressure;
commonly against penetration through capillary
attraction only.

7. WATER PROOFING

8. DAMP PROOFING
• A damp-proof course is a
horizontal barrier in a wall
designed to resist
moisture rising through
the structure by capillary
action - a phenomenon
known as rising damp

9. THERMAL INSULATION
• Insulation is defined as a material or combination of
materials, which retard the flow of heat. The materials
can be adapted to any size, shape or surface. A variety
of finishes are used to protect the insulation from
mechanical and environmental damage, and to enhance
appearance.
• Its helps in energy savings, fire protection, Sound
attenuation, greenhouse gas reduction.

11. Materials

12. Methods

13. SKYLIGHTS
• Skylights add natural lighting to dull, dark rooms by
adding a skylight. Skylights provide the simplest means
of introducing the daylight into a space under a flat or
pitched roof assembly
• FEATURES
1.Allows diffused light to enter.
2. Add to the aesthetic appeal of the viewer
3.Any of the shapes can be fabricated

14. SOLAR DESIGN
• It means the use of solar energy in various forms
to decrease the use of electrical energy and
increase human thermal comfort. It has two
components:-
• Passive solar design
• Active solar design

15. Passive Solar Design Techniques
• Orient the house with the long axis running east/west.
• Select, orient, and size glass to optimize winter heat gain and minimize
summer heat gain for the specific climate. Consider selecting different
glazing for different sides of the house (exposures).
• Size south-facing overhangs to shade windows in summer and allow
solar gain in winter.
• Add thermal mass in walls or floors for heat storage.
• Use natural ventilation to reduce or eliminate cooling needs.
• Use daylight to provide natural lighting.

16. BUILDING ASSEMBLIES
FLOORING AND ROOFING
Flooring-Flooring today
offers a considerably
wider choice in
materials, properties.
and appearance to
meet changing
performance criteria.

17. COMMERCIAL ROOFING
• COMMERCIAL ROOFING is
a building material used
to protect and seal the
top of commercial
structures. It covers
structural framing and
prevents rain and other
precipitation from
entering the
building. Commercial roof
ing generally has a
relatively flat slope.

18. STAIRCASES
• Stairway, staircase, stairwell, flight of stairs, or
simply stairs are names for a construction designed
to bridge a large vertical distance by dividing it into
smaller vertical distances, called steps.
• The following features were studied:-
• Stairway lighting
• Staircase design Considerations

19. Reinforced Concrete Stairs
• Categories depending on span of the stair
slab
– Stair with slab spanning horizontally
• Stair is supported on one side by
side-wall/stringer beam and on the
other side by a stringer beam
• Each step is designed as spanning
horizontally with B.M as WL²/8
• Main reinforcement – 12mm
diameter bars at 150 mm c/c
• Distributed reinforcement - 6mm
diameter bars at 150 mm c/c
• Waist of 8 cm is provided
– Stair with slab spanning longitudinally
• Slab is supported at bottom and
top of the flight
• Main reinforcement is parallel to
flight
• Distribution reinforcement is along
the width of flight

20. EXTERIOR WALL
• Bearing wall: wall that carries the load of floors and
roof above in addition to its own weight
• Curtain Wall: it is an outer covering of a building in
which the outer walls are non-structural, but merely
keep out the weather.
• Non-bearing Wall: non load bearing walls carry only
their own weight.
