The TERI University established and constituted in 1998, dedicates
itself to the study of environment, energy and natural resources for
attaining the far-reaching goal of sustainable development. The
campus is housed in a green building in New Delhi and is spread over
two acres of land, and is one of the first in the country for a university
and itfurther aims to minimize the ecological footprint.

The linear geometry of the site with a narrow frontage and an aspect ratio of almost
1:3 dictated the strong linear axis in the design.
The logical sequence of positioning the three distinct functioning zones in a hierarchy
of public access to restricted entry formed the other key consideration in design
development.

Placing the commercial block at the front was the most logical choice in exploiting
the commercial potential of the frontage of the site.
The functional core also coincides with the geometric central part of the linear site.
The residential zone comes up from the rear forming the last zone in the linear
sequence.
That the design responds to orientation and climatic factors, is but an obvious fact.
The north line is at a slight angle to the linear axis of the site and the design takes
full advantage of this orientation in the composition of the built and open spaces and
in creating wind flows through the complex as also lighting and shading of the spaces.

The Sun, Sky, Air, Water and Earth shape the nature of architecture which emerges on
this site. The process of continuous dialogue between the architect and TERI and the
engagement of TERI in the design process augmented the thrust on climate responsive
design in a large way.
Sun:-
Passive solar design is an important feature in the design of this building. The planning
and orientation of spaces and building blocks ensures glare free daylight in all regularly
occupied spaces. All the linear blocks are oriented in the East-West direction with
shorter facades facing the sun.
Most of the south west facing walls are kept blank
in order to protect the building from the harsh
south west solar radiations. Where the south west
walls have openings, they are protected by means
of pergolas or projecting balconies. The east, west
and south facades of the building have minimum
glazing.

Few of the south
facing walls are
mounted with
aero screen louvers
(Hunter Douglas) fixed
at an angle
of 35deg. This ensures
that the winter sun is let
in where as the summer
sun is blocked. The use
of louvers in front of the
glazed walls also
reduces the heating up
of the glass facade
considerably.
The walls that are exposed to the harsh solar rays have a stone cladding which is fixed to
the wall by channels. The air gap between the wall and the stone cladding in itself acts as
an insulation layer. On the western façade, rock wool insulation is also provided in the wall.
Energy efficiency is further enhanced by Vermiculite insulation in parts of the roof slab.

Maximum use of daylight and use of light
sensors to regulate the use of artificial
lighting in the interiors is another key design
strategy.
In areas where daylight is available, fixtures
have been fitted with continuous dimming
electronic ballasts. These fixtures are
controlled by light sensors which respond to
available light conditions and automatically
regulate the connected fixtures to achieve
the desired level of uniform illumination
required. In areas with non- uniform
illumination, occupancy sensors that can turn
off the lights when the space is unoccupied
have been installed. This kind of a lighting
system has a potential of saving 70% lighting
energy demand.
Use of efficient double glazing window units
help significantly reduce the heat gained
through window glazing in the summers and
the heat lost in the winters without
compromising on the day lighting integration
and the levels of visual comfort.

Air:-
The predominant wind direction is taken into account in designing the open spaces.
The central atrium acts as an air funnel defined by the other buildings. The opening
oriented in the prevailing wind direction catches the outside air and channelizes it
through a narrow stretch of the block before releasing it into the central court
area.
ELEMENTS OF DESIGN
The central atrium is also proposed to be covered with an automatic adjustable louvre
system (Vergola). The angle of the louvres can be adjusted to block the solar radiations
during summer and to allow ample sunlight during winter. The system is further proposed
to be integrated with photo voltaic panels. The louvres if kept closed can effectively
prevent rain water from entering the atrium during the rainy season.

WATER MANAGEMENT
• Building in the campus provided with low-flow fixtures such as dual flush toilets and sensor
taps.
• This would results in 25% savings in water use.
WASTE WATER TREATMENT
• Treatment of waste water generated from the hostel block by biological process using a
combination of micro-organisms and bio media filter.
• Low area requirement for this treatment plant.
• Treated water meets the prescribed standards for landscape irrigation.
• Very low energy consumption for operation of the treatment plant.

RAINWATER HARVESTING
• Average annual rainfall for Delhi is 611mm.
• Rainwater runoff from roof & the site will be used for recharge of aquifer through
CGWB-approved designs.
• Enhance the sustainable yield in areas where over-development has depleted the
aquifer.
• Conservation and storage of excess surface water for future requirements.
• Improve the quality of existing groundwater through dilution.

Earth:-
The campus is equipped with three types of cooling systems (i)Variable Refrigerant
Volume system (VRV), (ii) Earth Air Tunnel (EAT) and (iii) Thermal Mass Storage The VRV
system is proposed for the peripheral commercial block and the administrative block of
the institute. This state-of-the-art air conditioning system, which is similar to a split AC is
highly efficient under partial loading conditions and beneficial to areas with varying
occupancy. It allows customized control of individual zones eliminating the use of chilled
water piping, ducting and plant room.

EARTH AIR TUNNEL SYSTEM
It is used for free cooling / heating of the building for a major part of the year.
This technology uses the heat sink property of earth to maintain comfortable
temperatures inside the building. Supplementary systems have been used for
extreme conditions (monsoon). In such a system energy savings of nearly 50%
compared to conventional system can be achieved. At the campus, this system is
used for providing comfort for the rooms in hostel block.
VARIABLE REFRIGERANT VOLUME SYSTEMS
The VRV system is a modern air-conditioning system, similar to an efficient
version of a split air conditioner. The VRV system is highly efficient under partial
load conditions and therefore, has been used in areas with varying occupancies
such as the office block, laboratories, administrative block and recreation &
dining areas of the hostel block. It features customized control of individual
zones. Depending on the cooling demands of the building, variable refrigerant
volumes circulate through the chillers. The VRV system also eliminates the
requirement of a plant room; piping & ducting for chilled water; and contributes
to 15% energy savings as compared to a conventional air conditioning system.

THERMAL MASS STORAGE
Thermal mass storage is used in the classrooms. It involves storing energy
when available and using it when required. In the proposed arrangement,
cooling of the thermal mass is done during night (when ambient temperatures
are lower). During daytime when ambient temperature is high, the thermal
storage is used as sink for the fresh air requirement. Estimated energy savings
of up to 40% can be achieved with this system.

The use of Earth Air Tunnel gives an energy saving of nearly 50% as compared to the
conventional system
Thermal mass storage used for cooling the classrooms and labs involves storing energy
when available and using it when required. Here, cooling of thermal mass is done during
night. This cool thermal mass is used to cool air in day time. This system gives an energy
saving of up to 40%.

Earth:- EARTH AIR TUNNEL
The Earth Air Tunnel (EAT) is used in the hostel blocks. This is a dual heating-cooling
system using the heat sink property of the earth to maintain comfortable temperatures
inside the building. Air which passes through the buried pipes gets cooled in summer and
heated up in winter.
ELEMENTS OF DESIGN
A lot of research went in to the design of this
system. Airtron, the Air-conditioning
consultants for the project in collaboration
with faculty of Indian Institute of Science,
Bangalore simulated the system and refined
it to perfection. On continuous
uninterrupted use in extreme heat conditions
as in Delhi, this system faces the problem of
the earth around the tunnel getting heat
saturated and reducing the effectiveness of
cooling
A recovery time is required for the earth to dissipate the heat from the immediate
surroundings. After rigorous experiments and simulations a second loop of tubes was
created and the two loops used alternately to provide sufficient recovery time to
the earth around and maintain the performance effectiveness of the system.

Solar rooftop system at TERI University
• TERI University added yet another 'green' feature to its repertoire when a 48 kWp solar
rooftop system .
• The solar rooftop system has a separate 5 kWp R&D plant meant specifically for the hands-
on training of the students. This state-of-the-art grid-connected system comprises
polycrystalline PV modules and SMA invertors.
• It is expected to generate about 1.5 million units of electricity over 25 years, offsetting
15% of the grid electricity. It would also result in mitigating around 1400 MT of CO2
emissions.
• As per the power purchase agreement signed with the Renewable Energy Supply Company
(RESCO), the solar-tariff is, and will remain, substantially lower than the grid-tariff.
• The RESCO would also take care of the operation and maintenance of the system.
• However, the main motive for the University to opt for the solar rooftop system was to
bolster its philosophy of practising what it preaches, besides having something that
physically manifests the theory that is taught, thereby providing students an actual feel.

Architectural Expression
The form and massing of the campus
responds entirely to climate and the
site.
The south-west walls with few
fenestrations and stone cladding,
responding to the climatic conditions,
forms an impenetrable wall, providing,
as it were, a visual cue to the inherent
resistance of the structure to
inclement weather. Pergolas,
overhangs and balconies form visual
links as well as create drama in light
and shade.
The northern walls, in contrast, are
lightweight with their glazing and large
fenestrations, once again in response
to the site and climate. The louvers on
the glazing create interesting visuals
on the facade.

A Statement...
The TERI University Campus, with its
responsive design and use of passive and
active energy saving technology sets a
benchmark in sustainable campus design.
Building specifications adhering to Energy
Conservation Building Code (ECBC) are also
one of the key features of the design.
Many of the technologies implemented have
higher initial costs and longer recovery
periods, but the client being TERI, the focus
remained undiluted in applying sustainable
technologies with long term energy efficiency
targets.
A last word on the project echoing the
thoughts of Architect Sanjay Mohe: "The
campus being constructed for TERI, had to be
a truly climate responsive one and it attempts
to make a statement in sustainable campus
design."
