Energy savings through reporting E


nergy reports from the Desigo Building Energy Management System (BEMS) from the Siemens Building


Technologies division can enable organisations to better manage their energy usage.


Energy use in premises can be one of the most expensive outgoings of a business, with buildings accounting for more than 40% of the world’s energy consumption, so it is important to understand where and how energy is being used. To help organisations manage and monitor their energy consumption, Siemens offers Desigo Insight, a user- friendly management system through which Desigo Energy Reports can be run. Desigo Insight can be accessed via the Internet from remote locations, meaning that a user can remotely access reports and statistics from a number of sites via a PC in their office. Using data from field devices and collected by the BEMS, Desigo can display the readings in an easy to understand format, allowing users to analyse energy usage and plan energy


improvement measures.


The system provides report templates to efficiently generate the following energy-related reports: • Energy consumption • Energy costs • Weighted consumption • Adjusted heating degree days • Energy efficiency •CO2


emissions


Reports can also be automatically generated to contain the most up-to-date information, for example for monthly evaluations or even for reporting as part of the Carbon Reduction Commitment Energy Efficiency Scheme.


As well as analysing energy usage and highlighting areas for improvement, Desigo Energy Reports are useful in measuring the success of new energy- saving technology. For example, if an organisation invests in a new energy- efficient piece of equipment, or installs renewable energy technologies, then the reports can track the savings made. Reports can also highlight discrepancies in energy use, by


highlighting unusual peaks in activity which can indicate faulty equipment or that controls have been adjusted. For example, if the heating has been left on full overnight in an unoccupied building, this will be easy to identify. It also allows users with multiple sites to benchmark buildings across their estate.


Reporting in this way also motivates energy saving activities and behaviours, with staff able to see how their actions have resulted in reduced usage. Bringing building users on side ensures that Siemens Desigo Energy Reports are used to maximum effect and to generate most benefit for companies. www.siemens.co.uk/ buildingtechnologies


25% SAVINGS ON ENERGY BILLS F


acilities managers are saving up to 25% on electricity bills by reducing their energy consumption with iVolt – the only voltage optimisation equipment on the market that features a device capable of tracking and proving savings, in real time.


Based near Heathrow, iVolt produces


variable VO software that lowers and stabilises a site’s incoming voltage to reduce power consumption, electricity bills and carbon emissions, as well as prolonging the life of equipment. Already supermarket chains, hotels, factories, railways, schools and charities are using iVolt to address rising energy prices. One of those that’s benefitted is Surrey hotel Foxhills (pictured), which has seen annual savings in excess of £15,000 a year. Part of the global Sollatek group,


iVolt’s rapidly growing client list is down to its patented IRT Energy Monitor which, unlike other VO equipment, can demonstrate savings in real time. The data it generates can be accessed remotely, using a cloud-based GPRS, and is a crucial tool for anyone wishing to monitor savings precisely.


Company founder and electrical engineer, Manhal Allos, said: “Most VO

equipment doesn’t make the grade as potential savings can only be guessed at and in the current climate that isn’t enough to warrant the initial cap-ex. However, iVolt’s patented IRT Energy Monitor can demonstrate actual savings, which is a key tool for our customers.”


It is thought 400,000 UK sites would benefit from VO. Some 90% of these would save more energy with iVolt than with any of the leading fixed reduction systems on the market. For more information, visit www.ivoltsystems.co.uk
