Energy Saving Project Implementation Parndorf Designer Outlet

The energy audit report and AMR monitoring facility has proven invaluable in enabling us to implement a wide range of opportunities that have contributed to the significant energy, carbon and cost savings we’ve achieved so far.

Project Overview

McArthur Glen are Europe’s leading Designer Outlet Retail Group. Their commitment to providing the ultimate customer experience is matched by their commitment to minimising the group’s environmental impact through the adoption of forward thinking energy, carbon and water reduction operations and investment in cutting edge technologies.

Briar Associates have supported McArthur Glen for 9 years in minimising energy costs whilst identifying cost effective energy, carbon and cost saving opportunities across their UK and European Outlets. Recent energy audits and Automatic Meter Reading (AMR) strategies carried out across all 20 Outlets have identified potential group cost savings of over €1,000,000 per year through the implementation of practical, often no cost or low cost energy reduction measures.

Description

Keen to minimise the long-term environmental impact of their Outlets, McArthur Glen are constantly looking for opportunities to reduce energy consumption as this helps reduce carbon emissions and operational costs whilst supporting increased profitability.

The energy audits carried out have identified a wide range of practical, cost effective opportunities that will support the group’s wider ambitions. The installation of AMR (or the utilisation of consumption data from existing smart meters where possible), enables the automatic collection energy con-sumption data every half an hour. This can then be used to produce simple graphs to monitor, compare and target excessive energy consumption more effectively.

The installation of AMR on every fiscal meter is a key strategy as this can then be used to improve energy management and demonstrate savings more clearly. The graph below clearly demonstrates the benefits of both implementing energy savings projects and the use of AMR reporting at the Parndorf Designer Outlet where, following their energy audit, the site management team implemented many of the opportunities identified, resulting in a significant reduction in electricity consumption.

Based on the actual savings achieved to date, it is estimated that annual savings of over 550,000kWh, worth over €60,000 per year will be made on their electricity costs alone, representing a 22% reduction in electricity consumption compared to that used prior to the energy audit. Furthermore, savings are likely to be significantly higher due to the high electricity consumption at the Outlet for air conditioning systems during this summer, plus further savings on gas.

Projects Implemented to achieve the savings

The significant savings at Parndorf have largely been achieved through the implementation of no cost and low cost measures, including:

  • Adjustments to existing heating and cooling control systems (time and temperature)
  • Upgrades to existing automatic heating and cooling controls
  • Reduced lighting operation times
  • LED lighting upgrades
  • Automatic lighting control upgrades
  • Hand-dryer upgrades

The savings have then been proven using AMR data obtained directly from the Outlets existing electricity supplier, as smart meters are already installed at the site and the half-hourly data is therefore available via Briars Online system, for just a small annual charge.

It is also important to note that the implementation of the measures have enabled significant savings to be achieved with no adverse impact on the customer experience. In fact the availability of accurate energy consumption data from an AMR system actually enhances the role of the site Facilities Manager, making it simpler to manage energy and identify inefficiencies, whilst problems such as high overnight consumption or excessive plant operation can quickly identified and quickly resolved.
