Our range of energy services is based on practical experience gained over 10 years working with organisations of all sizes to measure, plan and reduce energy and waste.

So, whether you are a home owner, running a commercial business or a manager in industry OES can help.

Energy Audits/ Surveys

Whether you are a home owner, running a commercial business or a manager in industry OES can help.

Energy audits and surveys are all about saving you money. We identify where you can reduce energy usage in your premises and we help you come up with the best solution for your premises.

Residential and Domestic

The cost of energy has become a big part of the household budget at an average cost of over €1800 per annum. OES can carry out a survey in your home and help you come up with a plan for lighting, insulation, draught proofing, and controls to save your money. There is no need to worry about a major investment cost, up to 20% of your energy costs can be saved with little or no cost to you.

Industrial and Commercial

To stay ahead of the competitors, particularly in the current downturn, you need to keep a close eye on your margins. The cost of energy should be a major worry for all businesses. 30% of energy consumed by users is wasted, costing business millions. We want to work with you to identify how you can achieve efficiency, save money and keep ahead of the competition. All Integrated Pollution Control Licensed activities are required to carry out an annual energy audit. OES have provided this service for many industrial clients such as Glanbia Ingredients, ESB, Lee Strand Co-op and Killarney Waste Disposal.

Monitoring & Measurement

Once you have undertaken an energy survey OES recommend monitoring and targeting as the essential next step.

The purpose of monitoring and targeting (M&T) is to relate your energy consumption data to the weather, production figures or other measures in such a way that you get a better understanding of how energy is being used. In particular, it will identify if there are signs of avoidable waste or other opportunities to reduce consumption. Data collection may be manual, automated, or a mixture of the two. Once an M&T scheme has been set up, its routine operation should be neither time-consuming nor complex.

An M&T scheme will provide essential underpinning for your energy management activities, allowing you to:

  • Detect avoidable energy waste that might otherwise remain hidden.
  • Quantify the savings achieved by any and all of your energy projects in a manner that accounts fully for variations in weather, levels of production activity and other external factors.
  • Identify fruitful lines of investigation for energy surveys.
  • Provide feedback for staff awareness, improve budget setting and undertake benchmarking. Monitoring and targeting is an essential element of the process of continuous improvement.

Energy Management Systems

For many industrial and commercial clients OES have implemented energy management systems. The objective of the Energy Management System is to establish a systematic approach for improving energy performance and efficiency continuously. OES work with the client to ensure that energy management is a day to day part of business management and is a key performance indicator.

The Energy Management System is structured in a similar manner to the Environmental Management System, ISO14001. OES can assist on the implementation of an energy management system which is stand alone or can be integrated into existing systems on site. This approach ensures that a company benefits from the continued value-add of the management system, in the form of reduced energy costs.

The main benefits of the system are:

  • An organisation and its senior management demonstrate a strong commitment to energy efficiency.
  • Good energy management is embedded in normal operations
  • Action is based on key energy usage.
  • The emphasis is laid on getting it right the first time and on a process of continuous improvement.
  • Because of the need for participation by all staff, energy management does not depend on one person.

Processes are standardised so that improvements are sustained over time. OES Auditors are trained as Technical Assessors and Lead Auditors and have experience in the design and implementation of Energy Management Systems to the Irish Standard IS393.

Energy Efficient Design

OES have been involved in a number of projects involving the assessment of the design from an energy efficient perspective.

The key to effective energy efficient design is to get in at the start – as early as possible in the project life. This is not always possible and can be seen as a time delay and an unnecessary cost in a project where budget and time is tight. However, a small investment at the start can have immense savings over the project lifespan. OES can assist you in the following ways:

  • Mapping and analysing energy use and needs.
  • Identifying priorities. • Analysing available technologies.
  • Optimisation of process equipment.
  • Hand over to design engineers.
  • Input to tendering and contracts.

BER Assessments

OES have been involved in a number of projects involving the assessment of the design from an energy efficient perspective.

A BER is an objective scale of comparison for the energy performance of a building ranging from A1 to G. It is rather like the A to G rating for a household electrical appliances like your fridge. A-rated homes are the most energy efficient and G the least efficient.

Since last year for new dwellings and January of this year for all existing properties placed on the market or let, it is necessary to obtain a BER certificate. OES are specially trained BER assessors, registered by Sustainable Energy Ireland (SEI). In addition to carrying out the BER assessment OES will provide you with an assessment as to how the rating on your home can be improved. These would range from low cost measures such as increased attic insulation to more expensive options such as solar water heating.

Many home owners have difficulty in sifting through the wide array of companies offering alternative energy solutions such as ground source heat pumps, wood pellet boilers and solar water heaters. We can help you in deciding which, if any technology is suitable and most effective for your home.
