3. WHAT IS GREEN BUILDING CONCEPT???

•Green building (also known as green construction or
sustainable building) expands and complements the
building design concerns of economy, utility, durability,
and comfort.
• A Green Building is one which uses less water, optimizes
energy efficiency, conserves natural resources,
generates less waste and provides healthier space for
occupants as compared to conventional buildings.
•Green building is the practice of creating structures and
processes that are environment friendly and
resource-efficient throughout the lifespan of a building
right from site selection to design, construction,
operation, maintenance, renovation and
deconstruction.
•Green Buildings are designed to reduce the overall
impact on human health and the natural environment
by the following ways:
-Using energy, water and other resources efficiently.
-By reducing waste, pollution, and environmental
. degradation.

5. FUNDAMENTAL
PRINCIPLES

•STRUCTURE DESIGN
EFFICIENCY
•ENERGY EFFICIENCY
•WATER EFFICIENCY
•MATERIALS EFFICIENCY
•WASTE AND TOXIC
REDUCTION

8. •The foundation of any construction project is
rooted in the concept and design stages.
•The concept stage, in fact, is one of the
major steps in a project life cycle, as it has
the largest impact on cost and performance.
•In designing environmentally optimal
buildings, the objective is to minimize the
total environmental impact associated with
all life-cycle stages of the building project.
• However, building as a process is not as
streamlined as an industrial process, and
varies from one building to the other, never
repeating itself identically.
•In addition, buildings are much more
complex products, composed of a multitude
of materials and components each
constituting various design variables to be
decided at the design stage.
•A variation of every design variable may
affect the environment during all the
building's relevant life-cycle stages.

STRUCTURE DESIGN EFFICIENCY

9. ENERGY EFFICIENCY
●To reduce operating energy use,
high-efficiency windows and insulation in
walls, ceilings, and floors increase the
efficiency of the building envelope, (the
barrier between conditioned and
unconditioned space).
●Another strategy, passive solar building
design, is often implemented in
low-energy homes.
●Designers' orient windows and walls ,
porches, and trees to shade windows
and roofs during the summer while
maximizing solar gain in the winter.
●In addition, effective window placement
(day lighting) can provide more natural
light and lessen the need for electric
lighting during the day. Solar water
heating further reduces energy costs.
●Onsite generation of renewable
energy through solar power, wind
power, hydro power, or biomass can
significantly reduce the environmental
impact of the building. Power generation
is generally the most expensive feature to
add to a building.

10. WATER EFFICIENCY
•Reducing water consumption and protecting water
quality are key objectives in sustainable building.
•One critical issue of water consumption is that in many
areas, the demands on the supplying aquifer exceed its
ability to replenish itself.
•To the maximum extent feasible, facilities should increase
their dependence on water that is collected, used,
purified, and reused on-site.
•The protection and conservation of water throughout the
life of a building may be accomplished by designing for
dual plumbing that recycles water in toilet flushing.
Waste-water may be minimized by utilizing water
conserving fixtures such as ultra-low flush toilets and
low-flow shower heads.
• Bidets help eliminate the use of toilet paper, reducing
sewer traffic and increasing possibilities of re-using water
on-site. Point of use water treatment and heating improves
both water quality and energy efficiency while reducing
the amount of water in circulation.
•The use of non-sewage and greywater for on-site use such
as site-irrigation will minimize demands on the local aquifer.

11. •Green architecture also seeks to reduce waste of energy,
water and materials used during construction. For example,
in California nearly 60% of the state's waste comes from
commercial buildings .
•During the construction phase, one goal should be to
reduce the amount of material going to landfills.
Well-designed buildings also help reduce the amount of
waste generated by the occupants as well, by providing
on-site solutions such as compost bins to reduce matter
going to landfills.
•To reduce the impact on wells or water treatment plants,
several options exist. "Greywater", wastewater from
sources such as dishwashing or washing machines, can be
used for subsurface irrigation, or if treated, for non-potable
purposes, e.g., to flush toilets and wash cars.
•Rainwater collectors are used for similar
purposes.Centralized wastewater treatment systems can be
costly and use a lot of energy.
• An alternative to this process is converting waste and
wastewater into fertilizer, which avoids these costs and
shows other benefits.

•ECOLOGICAL CONCRETE.
(ADMIXTURE, DICALCIUM SILICATE
INSTEAD OF CEMENT).
•PAPER INSULATION PANELS.
MATERIALS USED FOR GREEN BUILDING
WOOL BRICK :
•Obtained by adding wool and a
natural polymer found in seaweed to
the clay of the brick.
•37% more strength than burnt bricks.
•Resistant for cold and wet climate .
•They are dry hard and don’t need to
be fired like other bricks.

TRIPLE-GLAZED WINDOWS :
•Super-efficient windows
•Stops heat to enter the
building from direct sunlight

14. •Concrete is a friend of
environment on all of its life stages:
From raw material production to
demolition.
•Crushed glass, wooden chips or
slag can be added to make it
sustainable concrete.
•reduces CO2 emission of the
building.
SUSTAINABLE CONCRETE
•They spend a large portion of the day absorbing
energy from the sun.
•Not fixed on the top of the existing roofing like other
solar units.
•Instead they are fully integrated into the building.
•Protects from weather
•As well as generates energy for the inhabitants.
SOLAR TILES
•Made from recycled newspapers and
cardboard
•Superior alternative to chemical foams
•Insect resistant and fire-retardant because of
borax, boric acid and calcium carbonate( all
natural materials )
•Can be blown into cavity walls thus filling every
cracks and creating an almost draft-free space.
PAPER INSULATION

15. ●Amount of energy used is equal to amount of
renewable energy created on the site .
●Reduce carbon emissions & reduce
dependence on fossil fuels.
●Buildings that produce a surplus of energy over
the year are called “Energy Surplus Buildings”
During the last 20 years more than 200
reputable projects claiming net zero energy
balance have been realized all over the world.
●NZEB buildings consequently contribute less
overall greenhouse gas to the atmosphere than
similar non-ZNE buildings.
Net Zero Energy Building
●They do at times consume non- renewable
energy and produce greenhouse gases, but
at other times reduce energy consumption
and greenhouse gas production elsewhere
by the same amount.
●Traditional buildings consume 40% of the total
fossil fuel energy in all over the world and are
significant contributors of greenhouse gases.

16. NZEB CONCEPTS
●Net Zero Site Energy :
A building that generates as much energy as
it uses on site. This is the most common use of
the “net zero” term.
●Net Zero Source Energy :
A building that produces( at least ) as much
energy as it consumes when compared to the
energy used to both generate and deliver the
energy to the site from a remote point of
generation( such as a power plant),plus the
energy consumption on the site.
●Net Zero Energy Costs :
A building that sells more power to the utility
than the purchase, utilities generally charge
more than they pay for the power.
●Net Zero Energy Emissions:
A building that generates (at least) as much
renewable energy as it consumes from
non-renewable sources.This energy can be
produced on-site or purchase. Buying
renewable energy credits to offset
non-renewable energy consumption counts.

17. WHY NZEB??
●Reduces Energy Consumption
●Reduces Greenhouse Gases (Carbon Emissions)
& Global Warming
●Reduces Dependence on Fossil Fuels
●Reduces Ozone Depletion
●Reduces Climate Change
●Protects Our Environment for Future
Generations

●All three stages -Passive design, Active design, and Renewable Design, which helped in achieving
the net-zero energy consumption of buildings.
●PASSIVE DESIGN - orientation : The building is north-south oriented, which is favorable for effective
ventilation. Two separate blocks connected through corridors for optimum integration with nature
and a huge central courtyard provided which again helps in better air circulation and provides
skylight also.
landscape: Greater than 50% area outside the building is covered with plantation especially native
plants that have been planted to reduce water consumption. Circulation roads and pathways are
softly paved to enable groundwater recharge. Ventilation:
Courtyard in the center of the building helps in air movement as natural ventilation happens due
to the stack effect. Windows and jaalis add to cross ventilation. Daylighting: The
courtyard provided with skylight which provides indoor natural sunlight. 75% of building floor space
is provided with adequate daylight, consequently reducing dependence on artificial sources for
lighting. Building Envelope and
Fenestration: Building Envelope Optimized, rock wool insulation used. The window uses
high-efficiency low heat transmittance index double glazed glass of U-Value 0.049 W/m2K, VLT

34. St. ANDREWS GIRLS HOSTEL
●LOCATION - GURUGRAM ,
HARYANA
●OCCUPANCY TYPE - HOSTEL
●CLIMATE TYPE - HOT & DRY
●PROJECT AREA - 2322 Sqm

35. New Delhi-based architecture firm Zero Energy Design Lab has built girls' hostel in Gurugram, India
that features a distinguished exterior and free-standing façade with hollow pigmented concrete
blocks and brick.
Named St. Andrews Girls Hostel, the hostel block is located at the St. Andrews Institute of
Technology and Management in Gurugram. Completed in 2020, the building explores the
intersection of education and sustainability through the lens of the vernacular.
Covering a total of 25,000 square foot (2,322-square-metre) Girls’ Hostel takes cues from the
adjacent Boys’ Hostel Block and the building is articulated with brick and fair-faced concrete, with
exposed structural members abutting the structure along all sides.

36. "The hostel's design empowers students with freedom of movement within an environment that
prioritizes thermal comfort and functionality to become an exemplar of zero energy design," said Zero
Energy Design Lab.
The hostel accommodates up to 130 students, with dorm rooms spread across four levels in addition to
hosting ancillary spaces like a pantry, recreational areas as well as social spaces.
On the ground floor, there are 12 double-occupancy rooms along with a double-height reception,
pantry, and indoor activity lounge where students can organize gatherings and social events.
"The design faced a series of challenges from conception to execution," said he studio.
"The primary design challenge was to create a secure hub for the girls — a campus within a campus
fitting into the urban master plan that did not restrict the movement while establishing a connection
with the outdoors."
The layout of the building incorporates indoor and outdoor spaces that connect physically and
visually at different levels to enhance interactions and social activities.

37. To bring in a sense of the exterior landscape, the architects designed the entrance foyer and lobby as
outdoor spaces to face the west and are connected to the pantry so that students can enjoy their
evenings outside with a spill-out into the green landscape.
"The lounge creates an intimate environment for studying
or conversation. Further, the adjacent internal landscaped
court features dense plantation to reduce heat gain
through evaporative cooling."
"From the core of the building towards the outdoor, the next transition is the second-floor terrace along
the building’s west façade that attracts students in the mornings and late evenings in summers and
serves as an all-day space to congregate during winters," added the architects.
The studio kept the staircases as hubs for social interaction. There is a subsequent transitional zone at
the heart of the building which is a staircase, aesthetically incorporated into the south facade,
connecting all the floors.

Transitional and circulation spaces such as bridges open into
lounges and pause points to create room for socializing and
group study. Since the bridges create a visual connection, they
enhance interaction and interconnection. They seamlessly
extend into the student lounges on multiple floors creating fluid
spaces.

38. For its façade, with limited space available along the northern façade of the hostel, the studio
created a double-skin façade that has been developed with the intention of creating a
semi-permeable layer that would help in shading and regulating the temperature between the
exterior and interior environments via a controlled airflow.
Designed parametrically, the parametric screen takes cues from the previously developed façade
that spanned the adjacent boys’ hostel within the institute. The Boys’ Hostel Block’s façade was
designed as an envelope in which the rotational angles of the brick were calculated in order to
block diffused and direct radiation.
The interior second skin provides a volume where the user can step out to a shaded environment
such as a balcony or court. For the material of the building, the building’s materialization is based
on concrete and brickwork that binds the different floors together. The columns are round in shape
to enhance visual appearance as well as physicality.
