Germany's Techem Energy Services Middle East, a specialist in recording and billing the consumption of energy and water, will be making its debut appearance at the Big 5 this week. Techem deals with energy efficiency and water consumption measurement, and offers products and services for consumption management that are designed to record how much cooling and water has been used in residential apartments. "Natural resources are becoming scarce all over the world and ever more precious," said Hans Altmann, regional manager for Middle East &North Africa. "Techem stands for the future-oriented topic: dealing efficiently with energy and water." The company intends to open up the Arab market for measurement and billing. Hans-Lothar Schafer, the company's international director, thinks there is great potential for the company in the UAE: "We have more than 50 years experience in measuring and billing. This makes us the first choice for property owners in the emirates."
