Some of our key projects are JSW Steel, Ernst & Young, Page Industries, Indus International School and Yokogawa.


To what extent is application of solutions as offered by firms such as yours dictated by price? What is the level of awareness and comfort in India for concepts like energy saving?

Note that there are 3 levels of engagement from a customer. The first one is on the customers own initiative to save energy and reduce his bills. The second stems from his urge or desire for sustainable habitat and corporate sustainability. The third is driven by government policies like mandatory energy audits. The price therefore varies and depends on the customer's budget. The level of awareness had improved to a great extent and customers are looking at innovative solutions and there is a huge market for such solutions.



Tell us of the various challenges in marketing green products and solutions in a country like India? Could you name some of the firms which are very receptive to employment of green solutions?

Most of the customers expect energy savings and immediate returns. Awareness of how an energy service works is slowly growing. However, the value proposition - varies from customer to customer.

Several big names in the Industry are conscious about their energy footprint. Few like Infosys, ITC, Godrej etc are already way ahead in the game of energy efficiency.



The Indian government has outlined plans to construct 100 smart cities. What is the role firms like yours can expect to play in the Smart City space?

Smart cities are all about being sustainable and it is our aim to ensure that every customer of ours achieves it from his built environment. Some of the services that are essential for a smart city are energy,
water and waste management, green buildings and factories, energy analytics, building energy efficiency, automation, renewable energy etc.

CASE STUDY: StyleMark are the world’s largest sunglasses manufacturer. In 2006 they shipped a phenomenal 35 million units and currently 1 out of every 3 pairs of sunglasses sold in the United States are made by StyleMark. As with many other large manufacturers, energy is becoming an increasingly significant component of their operating budget. In an effort to bring their spiraling energy costs under control they turned to Eniscope. A trial was set up on a key distribution panel in their main factory. Eniscope immediately picked up on a HVAC problem that had previously gone unnoticed. A simple strategy was recommended in response to the information revealed by Eniscope and within two weeks the energy consumption on that panel was reduced by over 50 per cent. This equated to a saving of over $10,000.




The Chilled Unit Energy Saver is a non-toxic wax food simulant contained in a protective enclosure that mimics food temperature. Once in place, the Chilled Unit Energy Saver transforms the fundamental operation of the refrigerator because it will now use food temperature as the signal to control its refrigeration cycle rather than changeable air temperature. The effect is a more efficient refrigeration cycle, where the individual cycle lasts longer but the frequency is reduced by up to 80 per cent. This can result in energy savings of up to 33 per cent without any compromise to food safety and quality.


CASE STUDY: Chilled Unit Energy Savers Safeway are one of the largest grocery retailers in North America with over 1775 stores. They have a strong commitment to environmental protection, which includes adopting proactive measures to minimise waste. In harmony with this policy, a prominent division of Safeway agreed to trial Chilled Unit Energy Saver on one of their frozen warehouses. This resulted in a stunning payback of 3 months.





LED halogen replacements can offer a solution that improves efficiency whilst saving costs. Simply fitted into existing sockets, the LED technology consumes 80 per cent less energy than a conventional halogen bulb, whilst lasting 25 times longer. In addition to this, with the LED replacements working at an improved 85 per cent efficiency they give off very little heat, reducing the risk of injury or fire. Considering these factors and looking at the savings in monthly energy costs, additional bulb purchases and maintenance, it is clear that this is a more financially viable option over standard halogen bulbs.

CASE STUDY: A luxury hotel in South-West England decided to replace the 35W halogen downlights in the corridors, bedrooms and lobby areas with our replacement GU10 lamps which consume only 3.7W each, in an effort to reduce their carbon footprint and reduce their high electricity bills. A six-week trial was initially carried out, replacing approximately 200 lamps with our LED replacements and an immediate reduction of over 70 per cent in total energy consumption was noticed in that part of the hotel. Taking account of the other energy-consuming appliances in these areas it was estimated that their power usage on downlighting in this area had been reduced by over 85 per cent.
