Measure it to manage it with smart meters

Measure it to manage it. This saying applies perfectly to energy management. Effectively managing energy use is virtually impossible with unreliable measurement devices in place or worse still, no measurements at all. Smart meters are a smart way to measure energy and water usage giving you more control over the amount of energy or water usage.

Smart energy meters:
Smart meters are indeed a smart way to get insight into your energy use which brings more security and a better environment. They can also enable you to get Smart Energy Reports that are a personalised guide to energy efficiency.

Other benefits of smart meters:

? You are able to generate simple graphs and charts showing you where you use your energy and money

? Consumption of gas and electricity is broken down. This implies that one can be able to view their spending at a glance

? Smart meters track consumption on a monthly basis enabling you to compare your own consumption against other similar households

? By tracking energy consumption and spending over time, one can be able to view the history and assess the impact of their energy efficiency measures over a particular period

Smart water meters:
Smart meters are not only used for measuring energy use, they are also used to measure water usage efficiency. Water efficiency is essential for management of sustainable water resources.

Water resources have been diminishing over time posing a challenge for water users and water suppliers to seriously look for ways to manage water efficiency. The need for accurate, adequate and reliable measurement and monitoring practices of water consumption in organisations can therefore not be overlooked.

Timely collection and analysis of water use data, and relaying this data in a timely manner to the water user, can result in significant changes in water use behaviour. Other benefits include instant detection of areas where water wastage is occurring e.g. leakages hence action is taken to save water. Similar to energy data, water data collected by smart metering systems is also vital in designing water efficiency and recycling systems as well as the improvement of demand management policies and programs.

The use of smart meters to monitor water consumption enables users to analyse, and interpret the data collected. This feedback enables users to change their behaviours.

Energy Audit – clearly clear?

An energy audit is an examination of an energy system to ensure that energy is being used efficiently. It is the inspection, survey and analysis of energy flows for energy conservation in a building. Energy audits can be conducted by building managers who examine the energy account of an energy system, checks the way energy is used in its various components, checks for areas of inefficiency or where less energy can be used, and identifies the means for improvement.

An energy audit is often used to identify cost effective ways to improve the comfort and efficiency of buildings. In addition, homes/ enterprises may qualify for energy efficiency grants from central government. Energy audits seek to prioritise the energy uses from the greatest to least cost effective opportunities for energy savings.

An energy audit is an effective energy management tool. By identifying and implementing improvements as identified, savings can be achieved not only on energy bills, but also equipment will be able to attain a longer life under efficient operation. All these mean actual dollar savings.

An energy audit has to be conducted by a competent person with adequate technical knowledge on building services installations, after which he/she comes up with a report recommending plans on the Energy Management Opportunities (EMO) for energy saving.

An energy audit culminates to a written report. This could show energy use for a given time period (for example a year) and the impact of any suggested improvements per year. Energy audit reports are then used to identify cost effective ways to improve the comfort and efficiency of buildings. The energy audit report therefore gives management an understanding of the energy consumption scenario and energy saving plans formulation.
Energy audit reports should always translate into action. No matter how well articulated, the energy management objectives are afterall, an energy audit (EMOs), all the effort will be futile if no action is taken. The link between the audit and action is the audit report. It is therefore important for the audit reports to be understandable for all the target audiences/ readers, all of whom may have diverse needs, hence the reason why they should be clear, concise and comprehensible.

What are the do?s and don’ts when writing energy audit reports?

Avoid technical jargon as much as possible; present information graphically; use different graphics such as pie charts, data tables. Schematics of equipment layouts and digital photos tend to make EMO reports less dry. Some of the energy audit software?s come in handy in the generation of such graphs and charts.
The climax of it all is the recommendations, which should be made very fascinating.

ESOS Facts on a Page

The UK?s ESOS energy saving program stands for ?Energy Savings Opportunity Scheme?. Its purpose is to reduce demand – and hence fossil-based pollution at both ends of the supply chain. It currently applies to large UK companies only. However its guidelines are also valuable input to smaller firms voluntarily going greener.

The program threshold is 250 employees and / or turnover or at least ?UK50 million. This affects approximately 9,000 UK firms, with others below the threshold wondering whether the government plans to lower it. In essence, ESOS requires that qualifying businesses complete comprehensive audits of energy use and opportunities at least every fourth year.

The plan is carrot and stick. Compliant companies will probably uncover significant savings when they stop and measure. They may even unearth carbon credits they can sometime exchange for cash. Reactionary firms who try to duck the issue will feel Her Majesty?s wrath through stiff penalties. In time, they may find it harder to attract investors. If ESOS affects your company, then the wise thing could be complying by the first deadline of 5 December 2015.

To do so, you must conduct an energy audit and report it to the UK Environment Agency. This comprises

  1. Measuring total energy use across processes, transport and facilities
  2. Pie charting 90% of this to identify areas that are energy intensive
  3. Singling out cost-effective energy-saving projects in high use areas
  4. Submitting your report to the Environment Agency ahead of the deadline

ecoVaro recommends affected companies do not leave this to the last minute. While having ISO 50001 may exempt some from ESOS, the regulations are far from straightforward and it will take months to reach complete clarification. We would like to suggest a more balanced approach.

ESOS is a wonderful incentive to save energy costs while contributing to a better future for the kids. The Energy Savings Opportunity Scheme is precisely that. The cost of energy has crept up on us to the extent that we have to do something, government or no government.

Measuring energy consumption is as simple as installing meters at critical points in the flow, and you probably have many of them anyway. Once you have your data you no longer have to crunch the numbers. ecoVaro can do this for you and return the result in the form of handy graphs and spreadsheets.

Denizon’s Business Continuity Services

Disruptions to business operations can be as catastrophic as a Hurricane Katrina or a 9/11 or as relatively trivial as a minor power outage or a planned shutdown. What ever the gravity, scope and duration the disruption has, your company should be able to handle each situation so that you can declare “business as usual” and really mean it. (more…)
