Geographical Conditions.• Chennai, sometimes referred to as the

"Gateway to South India,“• Located on the south–eastern coast of

India in the north–eastern part of Tamil Nadu on a flat coastal plain known as the Eastern Coastal Plains. Its average elevation is around 6.7 metres (22 ft), and its highest point is 60 m (200 ft).

• Two major rivers flow through Chennai, the Cooum River (or Koovam) through the centre and the Adyar River to the south

Climatic Conditions.• Chennai has a tropical wet and dry

climate• The coolest part of the year is

January.• Temperatures - 19°C –25 °C (66–

77 °F). • Average annual rainfall is about

140 cm (55 in).• The city gets most of its seasonal

rainfall from the north–east monsoon winds, from mid–October to mid–December.

Turbo Energy Limited

‘Energy Conservation Building system’.• BenefitsEnergy consumption less by 40%. Better Indoor Air Quality. Better Day lighting. Less water consumption 20% enhanced health and comfort of occupants. Optimized life cycle economic performance. Passive Architectural Design. Sustainable Energy Efficiency.• SavingsDesigned to save Rs.30 lakhs per annum on total energy cost. Reduction of carbon foot print will be 1000 Tons per annum.

Turbo Energy Limited (TEL).

The Structure.• Wall Double wall with stabilized soil cement

foundry sand bricks & Aerocon Block with 2 inch thick EPS insulation in between. This combination has U- Value of 0.054 Btu / hr.ft2. Which is much lower than required U-value of 0.124 Btu / hr.ft2.

• Roof Albido Paint on the Roof with Reflectivity of 82% and EPS under deck insulation with shading effect by solar reflective collector.

• Glazing Energy Efficient Double Glazing with Low –e Coating. This glazing has U Factor = 0.586 Btu / hr.ft2. SHGC = 0.24, High LTC, Has Day light & vision windows. Hardly uses artificial light during day.

The Structure.• Energy Efficiency measures Energy modeling and

lighting simulation done in the design stage using "‘whole Building approach" of ASHRAE standards. Base Building energy bench marking envelopes for HVAC and lighting systems done. Simulation by rotating building every 90 deg. Design and form of building leading to energy savings of 65%.Length of the building along east west with shaded portion in east & west for avoiding solar heat gain.

• Solar Air Condition System First Time a centralized Solar air – conditioning system of 90TR has been installed in India. Parabolic dish reflectors generate pressurized hot water at a temperature of 140 Deg.C. This is fed into a Pressurized Hot Water Fired Vapor Absorption Chiller generates chilled water used for air conditioning the building.

The Structure.

• Lighting Power Density (LPD) Building has both Celing and Task Lighting Building requires 0.6 Watt / sq.ft in Open office and 0.7 Watt /Sq.ft in rest of area against standards of 1.0 watt / sq.ft Outside lighting minimized to reduce night glow and impact on nocturnal environment.

• Lighting Control This building has on /off type day lighting control in Ground and first floor open office to reduce lighting energy consumption occupancy sensor with on /off light control provided.

The Structure.• BMS Building Management System for Monitoring and Validation of

design parameters on electrical energy, fuel consumption, water consumption, fire safety, building security with surveillance cameras.

• Indoor Air Quality CO2 sensors are installed in Air- conditioned spaces to control indoor air quality and optimize fresh air intake. This is done by reducing CO2 level without increasing heat load,for various occupancy levels: “Demand Controlled Ventilation”

• Wind Mill Transfers well water to tanks for horticultural use, by harnessing wind energy.

• Zero Ozone Depletion Effect Central AC plant does not use CFC or CHFC, but Lithium Bromide and water as refrigerant.

Renewable Energy • PV cells: 1200 W of Photo

voltaic cells to generate electricity from solar energy to for lighting of the office.

• Wind Turbine: 1 Nos., 5 kW mini wind turbine generates electricity. PV cells Wind Turbine Hybrid System for ups,lighting offices on cloudy days.

• Solar Lighting: Solar based street lighting. 150 nos of solar street light in the main roads.

Zero Discharge Site

• Rain water from roof harvested in Two Huge ponds through Hume Pipes. Water is being treated & used for Factory & drinking.

• Low TDS reduces Chemicals & frequency of regeneration. The surface water is allowed to percolate through percolation pits . This & Rain water ponds increases the water table level & the ground water quality improved compared to 2004.

• Treated Grey Water used for Garden Areas.

Solar Air Conditioning.

Solar Air Conditioning.• TEL has successfully installed one

ARUN solar boiler system for fulfilling its hot water requirements for operating a Vapor Absorption Machine (VAM) for air-conditioning/comfort cooling for its administrative block.

• The process of hot water generation for operating the Vapor Absorption Machine for air-conditioning with the help of ARUN solar boiler is as explained in the figure beside:

Sustainable Site• Minimum disturbance to the site• Extensive erosion & sedimentation control measures to prevent

erosion• Rain water harvesting • Open grid / pervious  paver block in pathways & parking areas

enhances water seepage in to the ground • Battery operated chargeable trucks for movement of visitors & for

Fork lifts /trucks in handling of materials inside the campus.

Water Efficiency• Zero water discharge building• The landscaping & irrigation system have been designed to reduce

irrigation water consumption by 58.9% from a calculated base line case

• Water Used is on-site captured rain water and on-site sewage treated waste water in conjunction with efficient irrigation system.

Energy & Atmosphere • 64.4% savings in overall energy consumption than a normal building• 25. 81% of the project energy cost is being offset by renewable site generated energy• The hybrid power ( solar pv cell &one wind mill )has an installed capacity of 25.6 kwh• Selected refrigerant HVAC & amp: R that minimize or eliminate the emission of

compounds that contribute to ozone depletion & global warming• 85% reduction in lighting consumption• Cavity wall with aerated blocks• Refrigerant impact per ton is less than 100• 150 solar street lights used in the campus• Water pumped from three open wells by the solar pv cell connected to pumps for

campus use.• Water is pumped by a wind mill from one of the open well for irrigating the garden

Material & Resources• Fly ash based bricks • Recycled glass, aluminum, ceramic tiles• Recycled wood• 90% of the furniture used is old & refurbished

Indoor Environment Quality• Indoor Air Quality is continuously monitored• Materials selected so as to have no adverse health impact on the

occupant• Adequate amount of fresh air in to the building & control of air

quality through carbon –di –oxide monitoring• Use of low volatile  organic company carpets paints adhesives &

sealants• 80% of the building is day lit• 100 % of the regularly occupied spaces have access to outside

views.
