ENERGY
achieve the target of 80% reduction in carbon emissions by 2050. It should also be acknowledged that in the process of achieving this target the UK will be building a leading edge industry, which will have access to a global green energy market estimated to be worth £3.3 trillion.
IS BUILDING PERFORMANCE KEY?
Building services account for between 60-80% of energy consumption in commercial buildings. Control systems play a crucial role in this and are potentially the single most important factor in using energy efficiently. However, over complex systems and hard to access data can render a control system at best sub-optimal or worse, a major cause of energy wastage as well as create an unpleasant working environment. Ensuring a building’s control system is performing optimally and tracking where wastage and poor performance are occurring can be difficult. When the system that you are expecting to alert you to this poor performance is actually the cause, it will not think it is necessary to tell you, and left unchecked will continue to waste energy. The installation of an analytics layer on top of the control system can yield huge insight and lead to major energy savings, and improvement of the working environment.
The function of a building management system (BMS) is to monitor and record the countless volumes of data relevant to the operation of mechanical plant and environmental control. This information is the key to operating any building at maximum efficiency but the volume of information is often so vast that it would require a team of engineer’s countless hours to analyse and find opportunities to improve efficiencies, which would impact excess energy usage. However, with the implementation of analytical software the task is achieved in hours and will provide immediate options to remedy energy wastage or poorly maintained equipment.
SO WHAT DOES THE FUTURE HOLD?
The Government has proposed to introduce the “Energy Savings Opportunity Scheme” (ESOS) to implement Article 8 of the EU Energy Efficiency Directive, which requires all large enterprises (those with 250+ employees and an annual turnover exceeding €50 million) to introduce regular mandatory energy audits by the 5th December.
The scheme will require approved assessors to carry out Article 8 compliant ESOS assessments to identify energy saving recommendations. The Government believes that these recommendations will lead to cost effective energy management for large organisations resulting in significant operational cost savings. Traditionally, there is an aversion to change instigated by Directives. However, in this case, there is a sound argument for public and private sector bodies to embrace the opportunity to maximise the energy efficiencies of their assets and thereby reconcile the UK’s future energy demand and supply requirements, achieve the 80% reduction in carbon emissions target and improve the international competiveness of UK exporters.

TOUCH THE SCREEN AND FEEL THE POWER
S
windon based combustion equipment manufacturer, G P Burners, is now offering an optional touch screen interface. The TSI5000 touch screen is available with all of the company’s new PLC controlled burners and may be retrofitted to existing equipment with PLC controls. It has been designed to simplify burner operation and assist engineers in maintenance and service regimes.
The 15” monitor features a clear graphic display for maximum visibility and ease of operation. The interface can monitor up to four boilers or burners. A functional status screen allows the operator to control burner enable, shutdown and set point adjustment. The TSI5000 incorporates embedded ACS450 software, which facilitates password protected access to the controller. User friendly, drop down menus allow engineers to programme and monitor a range of parameters, including fuel/air ratio settings, boiler performance, trending data and fault diagnostics. A new feature of the TSI500 is its ability to interface with a USB combustion analyser, allowing real time combustion parameters to be displayed on screen during burner set up. This allows the engineer to fine tune accurate air and fuel ratios for optimum burner efficiency, without leaving the unit, which significantly reduces set up time. The TSI5000 may be remotely accessed via a PC, tablet or mobile phone. This facility aids remote fault diagnostics, meaning that fewer engineer site visits are required and the correct replacement components may be despatched to site for first time fix. The system also provides for a mobile phone alert of burner lockout. The TSI5000 acts as a document store, providing a single source for engineers to access manuals and service records. The interface is currently available for operation in English, Italian or Russian, with other languages available to order.
