Blane Judd, Chair of the IET (The Institution of Engineering and Technology) Standards TC2.4 DC Power Systems talks through the relationship the IET has established with CEDIA.

Low and extra low voltage direct current (d.c.) power distribution offers an enabling infrastructure to manage the increasing numbers of direct current power devices in buildings – such as consumer electronics, building services, IT equipment, as well as solar photovoltaic and battery systems. It allows end users to avoid unnecessary power conversion steps, with potential benefits including carbon savings, energy efficiency improvements and optimisation of space utilisation in buildings.

Despite the strong growth of d.c. powered electronic devices essential to connected systems in buildings, d.c. power distribution has not had the same treatment as a.c. power either in the market or in standards world. Following industry consultation, IET Standards recognised the opportunity to work with key stakeholders to develop a Code of Practice in this area, and provide confidence to end users in the possibilities and appropriate application routes for (LV and ELV) d.c. in buildings.

CEDIA was noted as a leading group in the application of electronic systems in buildings, and was happy to nominate Guy Singleton of Imagine This Ltd as the CEDIA representative for the technical committee (TC2.4 DC Power Systems, of which I am Chair) overseeing development of the new standard. Guy has also provided his expertise in the editing group, working with the lead author and other technical experts from research and industry to feed in real world experience and to help ensure that the final document is written at the right level for practitioners to understand and use. Guy also stepped forward as a CEDIA representative to present at the KTN and IET Forum: Direct Current Energy Systems on Integrating DC Energy Systems into the Home Using Domestic AV Cabling.

Guy has served as a volunteer and representative with distinction to date, and I very much look forward to his continued support and involvement in moving the standard through the forthcoming Draft for Public Comment stage and into publication.

Guy Singleton comments: “As a volunteer for the CEDIA Standards committee, I am keen to work with institutions such as the IET. We are working towards positively influencing codes and standards relevant to, and for the benefit of the whole industry. My involvement in creating the IET Code of Practice for Low Voltage Direct Current Power Distribution in Buildings has been extremely interesting and I expect that the industry as a whole will benefit from it.”

The Draft for Public Comment stage for the IET Code of Practice for Low and Extra Low Voltage Direct Current Power Distribution in Buildings is expected to commence in November 2014. Further information will become available on the IET Standards website.
