It’s not a decision we take lightly. We have been in constant dialogue with Silverstone and agree that the uncertainty around large gatherings being permitted to take place by Autumn, together with the Chancellor’s announcement that the furlough programme will continue until October jeopardises safe and successful delivery.

We believe it to be in the best interests of visitors, sponsors and exhibitors to postpone the event to 26 & 27 May next year.

The live events provide the opportunity to drive electric vehicles from Jaguar Land Rover, Ford and Volvo around the international circuit and large conference rooms to cater for the excellent array of speakers. While we have been planning to enact social distancing measures and hygiene stations across the venue, the consensus is that postponing will ensure a smoother, safer and more successful event.

Given the high number of delegate registrations and excellent calibre of speakers we have assembled, we will be hosting several digital events over the coming months, beginning with EV week in July in conjunction with the new 2020 EV report.

We will provide details of our digital event calendar shortly, please get in touch if you would like to be involved in these.

The post Why you can’t afford to miss The Energyst Event appeared first on theenergyst.com.

The principle of new technologies improving on or complementing old ones is well established, and is clearly illustrated in the evolution of boiler controls

New technologies solve problems, increase efficiency and often give us greater control over day-to-day processes. And, in the main, each technological advance improves on the last to deliver better performance. This is certainly the case with retrofitted boiler controls, which have advanced considerably during the past 40 years.

1970s

In the 1970s, for example, “time delay” devices were introduced to try to prevent boiler dry cycling, where the boiler fires to replace heat lost through standing losses rather than in response to a genuine requirement for heat in the building or process. Unfortunately, these prevent the boiler from firing on the basis of a fixed time delay, rather than by temperature. Consequently, firing might be delayed even when there was a genuine need for heat in the building, resulting in suppressed temperature. Controls using a time-delay approach are still on the market and suffer from the same limitations.

1980s

In the 1980s, the introduction of microprocessors enabled building management systems (BMS) and building optimisation, with a positive effect on the efficiency and control of heating in buildings. These technologies have continued to evolve and, when properly commissioned and maintained, remain as the vanguard of boiler control in many commercial applications.

1990s

Nevertheless, most BMS are not configured to detect or control the ongoing problem of boiler dry cycling directly, so the 1990s saw the introduction of “load compensation” or “burner management” controls. Many of these result in lowering the boiler’s design operating temperature by 2-5°C, using a single temperature sensor to monitor the boiler’s return temperature. Without monitoring both flow and return water temperatures these devices cannot differentiate between boiler dry cycling and firing to meet a genuine demand for heat. Consequently the boilers cannot respond to a genuine demand and comfort temperatures can be compromised. Some of these devices also use a timer to record how long the burner has or hasn’t been firing – presenting this as actual energy saving – which isn’t the case. They can also cause issues with weather compensation and other control strategies and are not compatible with emerging control strategies.

2000s

These issues led to a new approach to address dry cycling in the early 2000s – Intelligent Boiler Load Optimisation – in the form of Sabien’s patented M2G. M2G is unique in that it does not lower set points or the system’s average temperature. Instead, it uses real time measurement and analysis of both flow and return water temperatures to identify the boiler load specifically and whether the boiler is dry cycling or whether there is a genuine heating demand. Furthermore, it is compatible with all current and future BMS. Indeed, the majority of the 8,000 M2Gs in use across Europe, the US and Asia are installed alongside modern BMSs. Analysis demonstrates average energy savings of 12% with payback approximately 18 months.

The future

There can be no doubt that buildings and their services will be expected to become ever more efficient in the future, in line with tighter energy consumption and emissions targets. Using the latest boiler controls, that also incorporate an element of future-proofing, is clearly the logical way to achieve greater energy efficiency.

In the last issue we looked at the first step of the Plan, Do, Check, Act model and focused on the energy planning process defined in ISO 50001. This article gives an overview of the second step, Do, or as ISO 50001 calls it, implementation and operation of an energy management system (EnMS). It is worth remembering that ISO 50001 is applicable to any type and size of organisations, irrespective of industry, geography or culture. 

Implementation and operation

This section of the standard has seven main requirements that turn the outputs of the energy planning process into action that is structured, communicated and where relevant documented. It is worth noting that documentation should be treated with pragmatism – where the standard requires documentation then it must be followed to achieve compliance, but it is unnecessary to create additional records unless they add value to your EnMS.

Competence, training and awareness

This requirement applies direct employees and subcontractors who impact on significant energy uses, which are identified in the energy plan. Flexibility of training methods is given, but should be appropriate to the role, responsibilities, education, skills and experience of each individual. Whatever method, appropriate records are required by the standard. 

Communication 

Communication is critical to the effectiveness of the EnMS, internal and external communication is required. It is expected that internal communication is a two-way process that considers suggestions for improvement of the EnMS. This is a key engagement activity.

Documentation

ISO 50001 does not intend bureaucracy and provides good flexibility for documenting the EnMS. This could be paper or electronic records, but also signage, diagrams, flow charts and dashboards that communicate the objectives, actions and achievements of the EnMS. 

Operational control

Responding to this requirement will vary significantly from organisation to organisation. The fundamental aim is to ensure that energy policy, targets and action plans are implemented within operational and maintenance activities.

Design

Ideally energy efficiency should be designed into the EnMS to maximise its performance from the point of implementation. This requirement states that the results of design activities are recorded.

Procurement of energy services, products, equipment and energy

Procurement has a significant impact cost, resource and efficiency. It is specifically addressed and procurement processes must be established, documented, evaluated and communicated. Life cycle analysis should be considered in evaluation. 

Summary

This brief overview of implantation and operation should give a flavour for the nature of the requirements of ISO 50001 and demonstrate its flexibility. The key conclusion is that ISO 50001 provides a scalable framework that can be implemented in the most appropriate way to your organisation to provide continual improvement of energy management.

In the next issue of we&e, we’ll look at the Check stage of the process. This essential step ensures that the EnMS is effective and continually improved. If you can’t wait until then you or if you want more information about implementing ISO 50001 visit www.nqa.com/enms or contact info@nqa.com
