Energy Survey Packages

An energy survey is a study of how energy is purchased and consumed in buildings/at industrial premises, with a view to identifying energy-saving opportunities. In many cases our surveys not only reduce energy use, but simultaneously address occupant comfort issues – a key factor in securing staff buy-in to energy saving actions.The depth of the survey depends upon client requirements and budgetary constraints. Energy surveys are a core activity for PowerTherm and we offer three alternative packages for you to choose from:

 
  Electrical Performance Analysed  
Electrical Performance Analysed
 
 

€1000 Scoping Survey
Concise Energy Survey
Comprehensive Energy Survey

 

€1000 Scoping Survey

If you have an individual site with an annual energy spend of less than €100,000, then this is the survey for you. This low cost survey has been developed to identify straightforward, cost-effective energy savings for small and medium enterprises. The survey involves an assessment of historical energy use, an onsite survey and preparation of a report. It evaluates electricity and gas tariff, the building envelope, office equipment, IT/comms rooms, lighting installation and control, heating system, cooling systems, ventilation plant, hot water system, catering and refrigeration. We avoid vague or general recommendations, and draw on our experience to quickly identify site-specific opportunities.

For sites spending over €100,000 per annum on energy, this survey is available at 1% of annual energy spend.

PowerTherm recently completed a scoping survey of RMG Chart, an office and distribution facility in west Dublin.

Concise Energy Survey

The Concise Energy Survey is a mid-range survey that provides a greater insight into energy use and energy saving opportunities than the Scoping survey. It is better suited to more complex sites where annual energy spend exceeds €100,000. It involves a benchmarking audit; one or more visits to site to gather data, take basic measurements and develop an understanding of the facility; analysis of major energy users; and preparation of a report. The Survey typically takes 3-4 days.

The Concise Survey is ideal for newer buildings where the objective is to identify savings from optimising the operation of the facility. The survey focuses on identifying low cost measures associated with improved housekeeping practices and equipment controls. It will also identify opportunities to achieve savings through more significant investments. In many cases we will quantify energy savings and give an indication of implementation costs.

Comprehensive Energy Survey

If you have a large and/or complex facility we recommend the Comprehensive Survey to gain a thorough understanding of energy use and a full analysis of the cost-benefit associated with energy saving measures.

Based on CIBSE guidelines, PowerTherm will undertake a survey of site energy consumption with a view to identifying all areas of potential cost savings. Where possible, savings will be quantified in energy (kWh), financial (€) and emissions (CO2) terms. The survey will typically focus on three main areas: energy supply, energy consumption and energy management.

Regarding energy supply, we will evaluate electricity tariffs/costs with a view to identify more economical structures and patterns of use. Particular care will be taken to evaluate Maximum Demand electricity tariffs.

Regarding energy consumption, the survey will focus on quickly identifying the primary uses of energy and where savings exist. The survey will involve extensive onsite measurement, data logging and a review of records, drawings, etc. the client may have available. Major savings are often to be realised simply by changes in operating practices and equipment control, and we take particular care to identify savings during periods of low occupancy, including a night survey of the facility. Savings may also involve an investment in modern energy plant, in which case an estimate of potential annual energy savings, along with implementation costs and payback period, will be provided.

Regarding energy management, PowerTherm will also identify how your methods of energy management could be developed to achieve, maintain and recognise further potential savings.

A complete analysis of all major energy uses at your site, along with benchmarks of energy performance for similar buildings, is also provided. Our clients often find that a Comprehensive Energy Survey is not only cost-effective in terms of identifying energy savings, but it provides them with a better understanding of how energy is consumed and how the facility should be operated to optimise energy use.
