tion facilities and retail outlets.” While Powerstar HV MAX can be used to replace older transformers on existing sites, or on sites where physi- cal space restrictions previously made voltage optimisation installations dif- ficult to implement, it is also well suited to new build developments. Mardapittas also emphasised that when it comes to energy management systems, and voltage optimisation solutions in particular, there is no ‘one size fits all solution’. “While there are a number of options out there, installing a tailored, engineered system is essential to ensure that elec- trical equipment is running efficiently, and that real energy savings are achieved,” Mardapittas said.
MAX benefits
Dr Alex Mardapittas, managing director of EMSc (UK), explains how key sustainability is in all new build developments, and how making the right choices at the planning stage can lead to substantial savings over a building’s lifetime
A
key benefit of new buildings is that every necessary measure can be taken at the outset to ensure they are as energy effi- cient as possible. Everything from insulation, double glazing, solar energy and efficient lighting can be utilised. However, one area that is often overlooked is the amount of energy consumed by the electronic equipment used in new buildings. Voltage optimisation is a technique that has been widely used across the globe as a means to provide an opti- mum supply voltage for a site’s equip- ment, and a way to reduce energy consumption and carbon emissions. The technology is inexpensive and simple to integrate at the planning stage, which should make it an attrac- tive proposition for new builds. However, with so many sustainability measures already in place when plan- ning new build projects, voltage opti- misation systems appears to offer fewer savings benefits.
New developments
As a result, voltage optimisation man- ufacturer, EMSc, which already offers its Powerstar and Powerstar MAX volt- age optimisation systems, has devel- oped its Powerstar HV MAX, a super low loss HV transformer with an amor- phous metal core which has been designed to meet the specific needs of new build developments.

new technology of the Powerstar HV MAX. “Older transformers have high levels of standing losses and the majority of modern transformers used on commercial sites use Cold Rolled Grain Oriented steel (CRGO) within their core, which still provide signifi- cant losses for buildings in compari- son to amorphous steel transformers. “Utilising the Powerstar MAX elec- tronic dynamic intelligent technology, Powerstar HV MAX is designed to ensure that voltage is supplied to a site at a constant, stable level regardless of the input voltage instability - a vital feature for sites with critical loads, secure data and important operations that require high levels of reliability and security such as supermarkets, data centres, hospitals, hotels, educa-

New build projects can utilise the Powerstar HV MAX to help achieve sus- tainability marks and high energy effi- ciency ratings through accreditations such as LEED. It also offers additional benefits, including reduced carbon emissions, guaranteed savings, simple installation, and a payback period of less than five years. In addition, the system is fully designed and manufac- tured in the UK to be 98% recyclable - another LEED measurement.
A new build project presents an opportunity to design-in energy sav- ings, and by opting for a voltage opti- misation system your energy consumption and carbon footprint will be reduced, your equipment will operate as efficiently as possible at all times, the lifetime of your equip- ment will be maximised, and your maintenance costs will be signifi- cantly reduced.
