Lighting critical to Renovation Wave Success

Paul O’Connor, LAI Chairman

The EU’s Green Deal and Renovation Wave initiatives are excellent programmes and will undoubtedly inform and underpin the policies adopted by Ireland as we seek to reduce both our energy use and carbon emissions. For the most part though they focus primarily on heating, cooling and hot water generation. These are indeed major areas of concern, and ones that offer significant potential for savings.

However, lighting offers as much, if not more potential for energy saving and carbon reduction. Lighting impacts every aspect of modern-day living, be it homes, commercial, retail, hospitality, leisure and public buildings, not to mention outdoor lighting. Also, the pace of development is phenomenal with massive gains being made on a regular basis.

Lighting has a major contribution to make in realising the energy saving and carbon reduction objectives of the Climate Action Plan. It can also help Ireland meet its obligations in respect of Article 7 of the Energy Efficiency Directive.

Moreover, with wellbeing now also high on the agenda, especially in the face of the Covid-19 pandemic and changed work practices, it offers additional benefits. The non-visual effects of proper lighting levels are critical to good health, promoting sleep and even recovery from illness, in addition to increasing concentration and performance levels

We are currently faced with two crises – the decline of the environment and Covid-19. Lighting is unique in that it offers huge benefits in tackling both at the same time.

Tom Ascough, Director, Symphony Energy.

There continues to exist a grey area between the consultant’s design aspirations and the final built product. Most importantly, whatever about the consultant and the contractor, neither the client nor the architect recognise this void and consequently there is no budget allocated to bridge it. Besides, it’s difficult to know if a bridging service has been successfully rendered until the building is operating comfortably and energy efficiently.

Without a budget, an optimally-configured installation remains mostly illusive. Neither the consultant nor the contractor can be expected to invest in this space without compensation. In any case, it’s a highly specialist “grey area”. And even if the gap was bridged, with such a huge budget to be allocated, there is always that risk of fraudulence looming on the consultant’s head. But thanks to the emergence of companies like Fully-Verified, the risks associated with transactions have been mitigated.

It needs to blend the consultant’s concept creativity, practical installation knowledge and building automation programming into a single service offering. Our experience is that clients will only take this seriously if they are assured they will benefit from energy savings. If they can get their heads around the concept of an EPC (Energy Performance Contract), then they know they are guaranteed the savings, or at least a risk-free attempt, at getting them.

Perhaps we’ve asked too much from installation contractors in the past by pressing them to meet us half-way through the “grey area” in order to salvage a modicum of the lost energy performance buried in the finer operational set-up of buildings’ M&E systems. To spare everyone the pain, we widened the remit of our consultancy practice to bridge the gap between concept and competition.

Through EPC Contractor Symphony Energy, we forged a new EPC offering that guarantees a sizeable energy saving release from  existing building M&E systems. This idea has been tested and has proven highly-effective on several projects. Savings of 50% are typical, although a number of projects have the energy dial crossing the 70% and 80% savings thresholds. So, before subjecting owners of existing building stock to high retrofit costs in an effort to play catch-up towards NZEB, first explore what can be done to get a deep retrofit effect without needing a deep retrofit budget.

Consultants working on new projects need not wait until their designs are struggling to deliver the desired energy performance in reality. NZEB ought to be more a concern for clients than their project teams. The pragmatic approach for everyone’s benefit is to ensure the client allocates room in the project budget to better achieve the desired energy performance at, and post, completion. This provides a high level of assurance that NZEB levels are achieved, and perhaps exceeded, for new projects. By having an EPC contractor involved in the project from the early design stages, the crucial link between concept and actual energy performance is, quite literally, guaranteed.

The stakes are high for anyone offering an EPC as the client can only win, but the provider may take a loss, perhaps a heavy loss. To mitigate risk, we had to be confident in our predicted engineering solution outcomes. We also needed to have integral involvement in developing control algorithms that precisely matched the engineering concepts under every conceivable operating scenario. We needed to be proficient in coding so we could at least recognise programming issues and live test the code to iron out any bugs that would stifle the intended outcome.

Ultimately, we found ourselves searching the global market for high-grade PLC/BEMS equipment that is built on open systems architecture so it can act as a systems integration point with all other BMS systems, and with practically all other open protocols associated with M&E equipment.

Such protocols range from BACnet, Modbus, Lonworks to OPC, Dali, KNX, EnOcean and mBus. Using Loytec equipment, we’ve been able to integrate existing BMS and other M&E equipment to provide a single composite operating platform. With code programming in IEC61131-3 and other standard web software, it’s been possible to deliver exactly the engineering solution from concept to completion.

A tailored smartphone app is developed for each building or site. This empowers the facilities and maintenance team with good visibility into the operation of their buildings and the ability to swiftly intervene where necessary. The app also enables manual control over various individual items of equipment, making maintenance procedures more efficient.

Our quest to conquer the energy gap in the “grey zone” has yielded some high-value operational and management benefits over and beyond the deep energy savings. The broader integration of the M&E systems data with a wider array of IIoT data and machine-learning enhances the automated identification of the control system’s dynamic, integrated, optimum performance points.

Herein lies the next generation of energy savings that are key to nailing NZEB targets and beyond. Now, all of this diverse data is gathered together with a suite of powerful analytical tools on a cloud platform. Apart from providing wider market access to these now-proven extraordinary energy savings capabilities, this empowers a major advancement for energy, facilities and maintenance management proficiency.

The cloud platform also makes it easier to identify and assess a near endless pipeline of future energy-saving measures, thereby serving to deliver upon the continuous improvement requirements of ISO50001 more effortlessly.

Informed decision-making requires accurate information

Enda Ruxton

Energy costs are typically among the top three operational expenses incurred by businesses. Consequently, large savings can be made by achieving small increases in efficiency. However, the greatest challenge lies in identifying precisely where best to make those savings.

Enter Enda Ruxton of Energy Supervisor … he has the experience and tools to reveal energy inefficiencies within a business, and the ability to devise customised solutions to tackle and eliminate them. An added bonus is that these monitoring measures can be installed on a temporary basis to begin with, thus ensuring that the solution proposed on foot of the information captured is guaranteed to deliver energy savings.

Energy Supervisor Ltd offers a variety of energy monitoring solutions capable of measuring electrical loads, oil and gas consumption, thermal energy utilisation and water usage. All tools and protocols are all based on existing standards, requiring no proprietary hardware or software for installation or data access. The hardware is specifically designed to be non-invasive, requiring minimal downtime on installation and reducing the up-front cost of implementation.

What cannot be measured cannot be improved                                                                        All of the data gathered by the sensor technology is reported through the Cloud to Energy Supervisor’s secure servers where it can be retrieved and analysed with the convenient click of a mouse. Precise activity-based, cost analysis can be performed on that data to reveal “hidden” energy wastage that can be proactively tackled and eliminated.

This analysis and targeted solution-solving is ideal when looking at different aspects of an operation. Take for instance the following examples:

Refrigeration                                                                                                                                                                               Older refrigeration and aircon systems can be inefficient in comparison to new products on the market, but providing clients with an estimated analysis based on product data sheets is very often not enough to convince them that investment in the new kit is worthwhile. Measuring the actual performance of existing systems and attributing costs based on activity provides real tangible costs for customers to instill them with the confidence to invest.

Energy monitoring systems can assist in maximizing the performance of expensive capital assets. For example, chiller systems require flow rate measurement to ensure that they are operating within manufacturers’ recommended tolerances during commissioning and during their operating life.

Heating                                                                                                                                                                                              Energy measurement of oil or gas consumption of a boiler, and heat output from the boiler, provides the boilers’ operating efficiency showing when maintenance is due. Finding out where heat use and heat loss is within the distribution network can be achieved using heat meters. These can also be used for individual billing.

Lighting                                                                                                                                                                                           The continuous debate between the merits of T5 lamps and LED products to substitute T8 flourescent lighting causes many people to invest without measuring the “before and after “effect of their investment. Hence they never know if their decision was the correct one. Various lighting products have different lumen/watt performances, coupled with different life expectancy and lifetime performance.

Additional benefits                                                                                                                                                                    Apart from the obvious direct energy related savings, there are numerous other benefits to consider. These include:

– The ability to forecast energy expenditure on a month-to-month business contributes to the cash flow management of any business;

– Measurement of individual machines and devices can be used to predict maintenance requirements, e.g., if a motor normally operates at 1.5Kw and the load increases to 2kw, this is an indicator that the mechanical device it drives needs maintenance, the motor is overheating etc;

– Bench-marking of multiple machines, production lines, individual sites;

– Use of the software as a decision support system for investment decisions;

– Use for implementation and measurement of ISO standards such as 50001;

– Automatic meter reading to allocate costs to particular cost centres.

What’s new with pumps? … Class A efficiency is the new benchmark

The change from standard efficiency to high efficiency pumps is driven by legislation via the ErP Directive that demands all circulating pumps move to a high efficiency model in new systems from 1 January 2013.

With the ErP Directive 2009/125/EC, the European Union is promoting climate protection further. This legal regulation for energy-related products – ErP for short – limits electricity consumption considerably, even for heating circulation pumps. In effect, this Directive signals the end of inefficient pumps.

Uncontrolled pumps are responsible for 20% of the world’s electricity consumption. This means that all pump manufacturers will have to cease production of standard-efficiency pumps from the end of this year.

Very often the imposition of new legislation or directives presents difficulties and challenges for the industry sector affected. This is not the case with the new ErP Directive. If anything, it will provide a business stimulus.

The running cost savings delivered by the reduced power consumption of ErP-compliant pumps is great news for the entire industry. Specifiers, and especially installers, are now armed with the ammunition to undertake a major pump upgrade/replacement campaign.

Calling all contractors – this is an excellent opportunity for you to increase your business while, at the same time, delivering value for money services – in addition to genuine costs savings – to your customers.
