Green Initiatives
The entire world is concerned about the carbon footprint and each of us collectively or individually is responsible. Our Organisation’s environment friendly approach dates back to early 80s when we began harnessing solar energy, wind energy and also harvested Rain Water in various locations of our Group Companies. In addition, the Turbocharger itself is a product which helps in reducing emissions that harm the environment.
We have been certified under ‘PLATINUM’ category by LEED USGBC (United States Green Building Council)
About TEL Green Building.
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.
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.
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.
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.
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
Wood
Hardwood is not used. 90% of the furniture used is old. Private Limited Parquet floor area with rapidly renewable bamboo floor used.
Soil
Minimised disruption during construction
Benefits
Energy 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 Architechtural Design. Sustainable Energy Efficiency
Savings
Designed to save Rs.30 lakhs per annum on total energy cost. Reduction of carbon foot print will be 1000 Tons per annum.
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, aluminium, 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.
Celebration of World Environmental Day.
WORLD ENVIRONMENTAL DAY is a day that stimulates awareness of the environmental & enhances political attention & public action, which falls on 5th June of every year.
Theme of WORLD ENVIRONMENTAL DAY was “Green Ethics” and the slogan was “Plan for the Planet”.
ENVIRONMENTAL DAY was celebrated on 5th June 09 at Paiyanoor plant by planting tree samplings. During that day, each and every employee has planted tree & watered the Plants.
