5. Osquare Teck GREEN BUILDING
Our concept is to develop an estate build with Green solutions/materials
(Timber, SIP), with solar panels on the roof to generate power.
Also, we intend to eliminates AC circuit from all appliances to be used in
the estate e.g Television will be directly powered with DC and all other
appliances.
The estate will have state-of-art technology for monitoring the energy and
environment (majorly Fire hazard). The tenants will be able to know their
bill and know the appliance that is consuming high energy.
Future Product:
We intend to have green cars to be introduce to our clients/tenants in
the estate to make our clients not to depend on petrol/gas or Diesel.

8. Architectural design & Site planning

9. Bioclimatic architectural principles
• Orientation
• Thermal mass
• Surface to volume ratio
• Positioning of windows, shading
• Selection of materials for wall, roof, windows, including insulation
• Landscaping
Buildings in hot climate…
• Orientation to cut off sun protected insulated windows external wall
insulation
• Lower surface to volume, lighter finishes, water as landscape element
Buildings in cold climate…
• Large windows to capture sun
• Thermal mass to store heat
• Minimum Shading
• Insulated walls and windows
• Darker finishes

10. Effect of efficient materials
• Roof and wall insulation reduced cooling load by 23%
• Insulated windows reduced cooling load by 9% (window to wall ratio
7%)
Use onsite sources
• Day lighting
• Natural Ventilation(night cooling)

11. Lighting Design

12. The passive solar practice of placing windows, or other transparent media,
and reflective surfaces so that, during the day, natural
sunlight provides effective internal illumination.
• Use of effective solar control strategies (overhangs) and high
performance glazings limit associated solar gains.
• Achieving this daylight credit will likely increase energy savings in the
Energy and Atmosphere credits. This is largely due to savings in the
electric lighting that results from well day-lit spaces.
• Minimize site lighting where possible
• Full cut off-luminaries
• Low-reflectance surfaces
• Low-angle spotlights

14. Water System design

15. Reduce potable water consumption for landscape by 50% over
a theoretical baseline design for the specific region.
Successful Strategies:
• Drought tolerant plants
• Drip irrigation, moisture-sensing irrigation technologies
• Recycled rainwater system
• Municipally-provided non-potable water source use
Water Use Reduction, 20% and 30% Reduction
Successful Strategies:
• Dual flush water closets
• Ultra low-flow water closets and urinals
• Waterless Urinals
• Sensor-operated, Low-flow lavatories
• Rainwater collection reuse systems
• Gray water reuse systems
Landscaping & Water use reduction

17. Energy management system

18. • Photovoltaic (Solar electric) is a device
which produce free electrons when
exposed to light resulting in power
generation.
• Photovoltaic does not release any of the
green house gases when in use.
• Photovoltaic uses a non-conventional,
renewable source of energy which has no
adverse effects on the environment.
• solar photovoltaic system
• DC-DC distribution System
100% energy savings over base building
Photovoltaic

19. • Plant trees in vegetation strips around parking lots or sidewalks.
• Filtration basins (filters)
• Detention Ponds / Retention Ponds
• Vegetated filter strips
• Pervious paving
• Vegetated/Garden Roofs
• Energy Star rated roofing systems
• High reflectivity coatings
Sustainability at Site

20. Heat, Ventilation & Air conditioning

21. The main purpose of commercial HVAC (Heat, Ventilation &
Air conditioning) systems is to provide the people working
inside the building with “conditioned “ air .
"Conditioned" air means that air is clean and odour-free, and
the temperature, humidity, and movement of the air are
within certain comfort ranges
• Systems may be clustered at a central location and serve an
entire campus of buildings
• Locate system away from acoustically sensitive areas of the
building
• Selecting efficient air conditioning based on your climate.
• Selecting the proper type of and efficient heating system for your
climate
• Designing and sealing air distribution systems properly.

22. • Replace CFC-based refrigerant.
• Consider non-refrigerant based cooling such as evaporative
cooling in dryer climates.
• Consider photovoltaic, solar thermal, geothermal, wind, biomass,
and bio-gas energy technologies
• Sophisticated Electrical Management Systems, Building
Automation Systems or Direct Digital Control systems inherently
include most of the required monitoring points.
• Combine carbon dioxide monitors with demand based ventilation.
• Consider adjustable under floor air diffusers, or thermostat
controlled VAV boxes.

24. Composite Commercial Building
• Solid state lighting
integrated into hybrid
solar day lighting systems
• Smart windows
• Photovoltaic roof shingles,
walls, and awnings
• Solar heating and super
insulation
• DC-DC distribution
• Intelligent building
systems

26. Green features and
sustainable technologies
Energy Efficiency
State-of-the- art Building Management Systems (BMS) were installed for real time
monitoring of energy consumption. The use of aerated
concrete blocks for facades reduces the load on air-conditioning by
15-20%. Double-glazed units with argon gas filling between the
glass panes enhance the thermal properties.
Zero Water Discharge Building
All of the wastewater, including grey and black water, generated in
the building is treated biologically through a process called the Root
Zone Treatment System. The outlet-treated water meets the
Central Pollution Control Board (CPCB) norms. The treated water
is used for landscaping

28. Minimum Disturbance to the Site
The building design was conceived to have minimum disturbance to the
surrounding ecological environment. The disturbance to the site was limited within
40 feet from the building footprint during the construction phase. This has preserved
the majority of the existing flora and fauna and natural microbiological
organism around the building. Extensive erosion and sedimentation control measures
to prevent topsoil erosion have als been taken at the site during construction.
Materials and Resources
80% of the materials used in the building are sourced within 500 miles from
the project site. Most of the construction material also uses post-consumer and
industrial waste as a raw material during the manufacturing process. Fly-ash
based bricks, glass, aluminum, and ceramic tiles, which contain consumer
and industrial waste, are used in constructing the building to encourage the usage
of recycled content. Office furniture is made of bagasse based composite wood.
More than 50%of the construction waste is recycled within the building or sent to
other sites and diverted from landfills.

29. Renewable Energy
20% of the building energy requirements are catered to by
solar photovoltaics. The solar PV has an installed capacity of 23.5 kW.
Indoor Air Quality
Indoor air quality is continuously monitored and a minimum fresh air
is pumped into the conditioned spaces at all times Fresh air is also
drawn into the building through wind towers. The use of low
volatile organic compound (VOC) paints and coatings,
adhesives, sealants, and carpets also helps to improve indoor air quality.

30. Other Notable Green Features
• Fenestration maximized on the north orientation
• Rain water harvesting
• Water-less urinals in men’s restroom
• Water-efficient fixtures: ultra low and low-flow flush fixtures
• Water-cooled scroll chiller
• HFC-based refrigerant in chillers
• Energy-efficient lighting systems through compact fluorescent light bulbs(CFLs)
• Roof garden covering 60% of building area
• Large vegetative open spaces
• Swales for storm water collection
• Maximum day lighting
• Operable windows and lighting controls for better day lighting and views

31. Cost and Benefits
This was the first green building in the country. Hence, the incremental cost was
18% higher. However, green buildings coming up now are being delivered at
an incremental cost of 6-8%. The initial incremental cost gets paid back in 3 to 4 years.
Benefits achieved so far:
• Over 120,000 kWh of energy savings per year as compared to an ASHRAE 90.1
base case
• Potable water savings to tune of 20-30% vis-à-vis conventional building
• Excellent indoor air quality
• 100% day lighting (Artificial lights are switched on just before dusk)
• Higher productivity of occupants
