Buildings account for a significant part of energy consumption, while emitting large amounts of greenhouse gases. Building-related carbon reduction measures are among the most cost-effective, which include insulation, lighting, air-conditioning and hot water supply. Increasing the energy efficiency of buildings will greatly reduce the amount of energy used by mankind. Green buildings can be environmentally-friendly, energy-saving, practical and comfortable, as well as part of its surrounding biodiversity. For this reason, we not only promise that all future Delta buildings will be green buildings.
When planning new buildings, Delta focuses on a safe and pleasant working environment and on minimizing waste, emissions and energy and water use. Most of our new production plants are certified green buildings according to various national standards. Energy efficiency has been sought from the very beginning of building design all the way to daily operation. Important factors include architectural decisions, advanced air conditioning systems, optimization of ventilation, and utilization of solar power and high-efficiency lighting solutions.
Rudrapur- Delta India’s Rudrapur plant uses sustainable energy-saving practices and a waste management system and is registered with the Indian Green Building Council. The plant achieved the Green Building Standards required for the levels of certification under the USA Leadership in Energy & Environmental Design (LEED) India Green Building Council (IGBC) and received “Gold-Rated” Green Building accreditation .
Some of the energy-saving practices and waste management systems in Rudrapur plant include:
Lighting Upgrades Installation of sky lights, turbo ventilators, sun reflecting films usually save thousands of KWH energy and thousands of CO2(reduction in GHG emission)
APFC PANEL ( electricity recovery ) – By using this technique we have saved around 350342 KWH of energy and around 293.6 tons of CO2 from Jan’09 to April’11.
Photovoltaic cell installed at admin area (electricity recovery ) – By using this technique we have generated 20253 KWH of energy, thereby reducing GHG emissions by saving 16.2 tonnes of CO2 from Jan’09 to Apr’11
Burn in chamber (electricity recovery ) – Delta saved an estimated 595770 KWH of electricity in period Jan’09 to April ‘11 by recovering over 70% of the electricity using ERS system expended in the product burn-in process. Therefore by this process 4944 tonnes CO2.
Water conservation measures – Delta saved about 10106 KL of water through water conservation and recovery measures such as STP and rain water harvesting from Jan’09 to April’11.
Natural light harvesting, linear panel Polynum insulation, Power factor controller and Turbo ventilation helped in further saving electricity..
Gurgaon-Our new corporate office in Gurgaon is built adhering to the Delta’s Green Building policy. The new building is designed using energy efficient architecture, eco-friendly building materials, and building management systems that provide a vibrant clean, healthy and safe workplace for employees. Delta India has applied for a platinum rating for this new corporate office in accordance with the guidelines of the Indian Green Building Council’s LEED standards.
Major Green features incorporated in the new building include:
35% energy savings compared to a conventional building: a rooftop solar energy solution with a capacity of around 55 kWh of energy, use of LED streetlights, T5 and LED lighting, natural light harvesting, screw compressor based water chillers with COP (coefficient of performance) of 6, and primary variable pumping coupled with heat recovery wheel;
40% reduction in water compared to a conventional building: installation of an anaerobic sewage treatment plant, use of recycled water for non-consumption applications such as flushing and gardening purposes, rainwater harvesting pits, Grass-Crete for surface water recharge, and local low water consuming plantation;
Eco-friendly materials: use of autoclaved aerated blocks, fly ash in the concrete aggregate mix, gypsum and Bagasse wood, recycled aluminum, double laminated glass with insulation using Low-E glass in the structural glazing and fenestrations, and zero VOC (volatile organic compounds) paints and adhesives;
Healthy environment: VAVs (variable air volumes) using non-ozone depleting R 410-A as the refrigerant gas, and eco-friendly housekeeping practices
