Report on Standby Basket of Products - Indian Store Survey results

Sept 2010 

 Prepared by Sandeep Garg, Energy Economist, BEE, India and Mohit Verma, Consultant, CLASP-BEE, India

"The project “Standby Basket of Product Survey in India” was initiated by the Bureau of Energy Efficiency (BEE), Ministry of Power, Govt. of India, as part of the Asia Pacific Partnership on Clean Development and Climate Change (APP). The purpose of this project was to measure and collect the standby power data from a range of common household appliances found on display in retail stores in India. Furthermore, the project aimed at briefly assessing the collected data, in order to indicate the characteristics of a cross-section of the current appliance market. The project was carried out to contribute to the pooling of standby data in order to track standby power trends over time at the national level. The project covered retail outlets in major cities of India."

Measurement of Power Consumption of Set-top Boxes

May 2007

Prepared by S.A.L.T., a joint venture between Swiss Agency for Energy Efficiency (S.A.F.E.) and HTW Chur (College of Science and Technology)
Eric Bush, Max Schalcher, Peter Kühne, Stefan Kammermann, Stefan Gasser, Jürg Nipkow

 "The aim of this project was to obtain more information about the power consumption of set-top boxes. For this purpose, measurements were carried out on 33 set-top boxes, the results of tests carried out by “Stiftung Warentest” were evaluated and manufacturers were asked to provide technical specifications. In this way, a total of 80 models were evaluated."

Energy Measurement of Single-Phase UPS Devices

November 2007

Prepared by S.A.L.T., a joint venture between Swiss Agency for Energy Efficiency (S.A.F.E.) and HTW Chur (College of Science and Technology)
Eric Bush, Max Schalcher, Peter Kühne, Stefan Kammermann, Thomas Bruggmann

"In this project, 46 single-phase UPS devices in the power range from 350 VA up to 3000 VA could be measured with regard to efficiency and energy consumption.  The classification into VFD, VI and VFI devices and the performance of the measurements were carried out in accordance with IEC 62040-3 with resistive and non-linear loads.  As expected, the VFD devices showed the best efficiency level, followed by VI and VFI devices.  The efficiency rate at 50%, 75% and 100% of the nominal power differs only slightly, and in most cases exceeds 90%. However, at a load of 25% the efficiency decreases considerably (in individual cases to below 80%).  There are large differences in the area of standby losses (switched on, without load) which can only partly be explained by the different technologies of the various types of UPS  devices.  Compared to the Code of Conduct for UPS devices with a power of more than 10 kVA, the devices with lower power compare relatively well, especially because of the small power demands for cooling.
