Energy Metering and Management

Energy costs are rising.

And the initiatives to reduce a building’s overall carbon footprint are as well.

What can we do?

The answer: An Energy Management Program.

There are many aspects involved in an energy management program.

Cooling and heating a campus, commercial building, or other large facility canrepresent over 33% of total energy consumption.

Thermal energy measurements are required to properly assess energyconsumption, as well as control the distribution of chilled and hot water.

Energy Metering and Management

How does thermal energy metering work?

The management of thermal energy (cooling and heating) in a building isaccomplished through sub-metering and main chiller systems metering.

With sub meters on each floor or for each tenant, building owners candetermine where the most energy is being consumed and pass along costsor work to reduce energy costs. Steam, hot water and cool water ispumped into a building via a central heater/chiller or the district energyutility. Flowmeters and temperature sensors can measure the flow andDelta T to calculate BTU’s consumed.

A meter system by floor or by tenanted space will allow developers/managers/engineers to allocate costs, or identify consumption issues.

Energy Metering and Management

There are two steps to determining how much energy is consumed in the heating or cooling of a facility.

Say you have a high rise building that you need to cool. You’ve got chillersgenerating cold water to circulate throughout the building in a closed loop. Wateris pumped into the building at 24 degrees, and returns to the chiller at 52 degrees.

To find out how much energy was consumed, you need to measure the flow andtemperature of the chilled water as it enters the building, as well as thetemperature of the water as it returns (the flow should be constant, since this is aclosed loop).

So, in order to determine the energy consumption, you need to measure flow andDelta T to calculate KW’s consumed.

Energy Metering and Management

You know when you are consuming the most energy, when you are not, and exactly what it is costing you.

With that information, you can determine what you need to change to lower your energy costs.

But, that’s only half the story.

You may have multiple tenants in your building, and want to charge them based on their energy consumption.

Even if the entire building is the same organisation, you want to know where your greatest energy consumption is, so you can manage it.

That’s where main and sub-metering comes in.

Energy Metering and Management

Sub-metering gives you the precision that you need to pinpoint exactly where you are consuming the most energy

– to either pass along the costs, or take steps to lower energy consumption.

So, if you place flowmeters and temperature sensors at each floor, and use the same calculation, you can better determine those areas of energy consumption.

Distribution can then be monitored throughout a building, providing the necessary data for:• optimisation• balancing• billing• development of a strategy to reduce consumption

Energy Metering and Management

Thermal energy calculators are ideal as a stand-alone device.

It takes an input from a flow meter along with the supply and returntemperature of the chilled water (CHW) or hot water (HW) to provide athermal energy output.

The benefit of a stand-alone thermal energy calculator is it allows the enduser to pair it with any flow meter (e.g. Magnetic, Clamp, DP) giving theflexibility to apply the appropriate flow meter technology to various CHWand HW measurements (e.g. new installation, existing, etc.).

Thermal Energy Metering –AUS Standards

There are no Australian standards but EN1434 standard is commonly adopted/referenced

• Accuracy based classification - energy • Class 1 ±1% • Class 2 ± 2% • Class 3 ± 3% • Temperature ±0.5% (can be larger at high differentials)

Thermal Energy Metering –AUS Standards

The National Measurement Institute (NMI), a division within theDepartment of Industry, Innovation and Science is Australia's peakmeasurement body responsible for biological, chemical, legal, physical andtrade measurement.

There are no current NMI Pattern Approval Requirements:

“... at this time NMI has no formal requirements regarding the pattern approval and verification of thermal energy meters (a.k.a. heat meters)”

NABERS

NABERS is a national rating system that measures theenvironmental performance of Australian buildings, tenancies andhomes.

NABERS measures the energy efficiency, water usage, wastemanagement and indoor environment quality of a building ortenancy and its impact on the environment and its performance israted on a 1-6 star scale.

Green Star Green Star is a national, voluntary, holistic environmental rating system thatevaluates the environmental design and construction of buildings andcommunities.

Green Star rating tools help the property industry to reduce theenvironmental impact of buildings, improve occupant health andproductivity and achieve real cost savings, while showcasing innovation insustainable building practices.

• Stainless Steel transducer covers, conduit cable → rugged

• Lemo connector→ water tight

• Paired transducers → precision

(typical zero point error < 0.005m/s)

• Calibration can be traced back to international standard; calibration certificate acc. to ISO 9001

• Transducer data in EPROM→precise measurement→avoids input errors→accelerates start-up→traceable documentation

Flexim’s Permanent Coupling Foil

Transducer

PipeNon-Liquid Coupling Foil – Flexim now employ a dry coupling using a Vitonpad. This means that the transducer can be installed underneath insulationwithout ever needing maintenance – the system is truly maintenance-free!

The transducer must make direct contact with the pipe without thepresence of bubbles. Historically, this was achieved using a silicon gel.Unfortunately, this gel slowly evaporated and needed to be re-applied.
