Lighting & Controls

In addition to maximising the amount of natural light reaching a space, there are a range of options for making artificial lighting systems more efficient.

A trend in recent years has been to distinguish between ambient lighting and task lighting. Where once 100 per cent of lighting would have been provided by ceiling-level lights, many buildings are now opting for designs where ceiling-level or ambient lighting only provides 30 per cent of the light needed for a space. The remainder is provided by task lighting (such as desk lamps) which is positioned much closer to workers and can be turned on and off as required.

Energy efficient alternatives now exist for most forms of artificial lighting.

T5 light fluorescent tubes are smaller and more efficient than standard (T8) tubes, and have been used in many commercial buildings. Compact fluorescent bulbs can replace standard incandescent bulbs.

LED is the most efficient lighting technology and is now the product of choice for many clients, energy consumption reductions are generally in excess of 50% and the cost of luminaires are now reaching parity. LEDs are maintenance free and last much longer than traditional light sources; they can maintain light levels for 100,000 hours and longer in most cases.

Control systems also play a major part in lighting energy efficiency. Energy is wasted every time someone forgets to manually turn off a light. Automated systems which connect lights to motion and daylight sensors can negate this problem. The sensors can dim or switch off the lights when there is enough daylight entering the space, or when motion detectors don’t register any people in the space.

LED Lighting

The majority of our LED lighting technologies are plug-and-play solutions which are suitable for the direct replacement of a traditional incandescent, halogen, metal halide and fluorescent luminaries.

The aim is to make the installation as seamless as possible. Ensuring businesses can implement a total LED solution as soon as possible, without the hassle and mess of replacing housings, altering existing fittings and replacing transformers.

LED lighting has advanced significantly over the last 5 years which has seen a major shift in both the way business and facilities consider light, and also the focused on the issue of energy consumption of older, inefficient, lighting technologies.

NuGreen Solutions is one of Australia’s leading LED Lighting solutions providers having audited, designed and installed new LED lighting installations at some of the countries largest facilities and for many top 500 companies. Our ‘Product Agnostic’ approach enables NuGreen to select the right LED lighting solution for your specific project, sourcing the ‘Best of Breed’ technology from the world’s leading manufacturers.

Benefits of LED Lighting:

  • Improved Productivity: Workers report less fatigue when working long hours under LED light because of less eye strain. Studies have shown that workers can be 6-8% more productive under LED light.
  • Healthier Light: LED lighting emits no ultra-violet (UV) or infra-red (IR) light. Because of this, LED lighting will not harm the eyes or skin.
  • Improved Energy Costs: LED lights can save up to 80% in lighting energy costs! This translates directly to lower energy bills, reduced operating costs and improved cash flow.
  • Improved Maintenance Costs: LED Lights can reduce maintenance costs between 70%-90%
  • Carbon Tax Benefits: LED lights can help your business achieve your Carbon reduction commitments
  • More durable: LED lights contain no high-pressure gasses or thin filaments. This makes them highly-resistant to vibration and temperature changes. In addition, their lack of glass makes them safe for use in and around food manufacturing, preparation and storage areas.

  • Long Lifetime: Very long lifetimes are expected from 50,000 – 100,000hrs operation. That’s more than 5 times longer than fluorescents and 30 times longer than halogen bulbs
  • Improved Efficiency: LED lights produce more light per watt than incandescent and halogen bulbs
  • 100% Recyclable: LED Lights contain no harmful elements like mercury and are 100% recyclable. That’s less environmental impact and no special disposal requirements. LED lighting can be an important component in helping your building or facility achieve a high NABERS/Green Star performance rating
  • Instant On: LED lights turn on instantly and are dimmable. LED lights do not require a long warm-up or cool-down period before they can be turned on. They are also dimmable down to 1% without losing their colour temperature.

NuGreen Response

NuGreen Response is a highly flexible lighting management system that can reduce energy consumption by up to 85%*.

It is simple to install, self-configuring and self managing.

Electricity and maintenance make up a large portion of lighting costs associated with the overhead expenses in a commercial office facility. These facilities can often run lights for up to 24hrs a day. By upgrading to an intelligent light solution – combined LED and in-built Sensor Technology this can provide a significant value.

By merging these technologies the end result will create a comfortable and healthy working environment for staff. With numerous funding options available through government grants and with the long term leasing options offered by NuGreen, these improvements are now achievable with minimal to no capital outlay required and extended maintenance free warranty over the period.

Sensors & Controls

Motion sensors detect when a person is moving in a space.

They can be used in buildings to control various systems, such as turning lights or air conditioning off in areas where no movement is detected. This can result in significant energy savings, as the lights or air conditioning get turned off regardless of whether someone remembers to flick the switch or not.

Commercial Solar

System Design & Install

Our Commercial Solar Division covers power systems installed on rooftops and constructing new car park and ground mount installations for organisations across Australia. Anyone who wants to offset electricity from the Grid can benefit from a Solar PV installation.

The benefits of producing some or all of your organisation’s power requirements from a Solar PV installation system are obvious. A Solar PV installation will reduce your electricity bill, and with electricity prices forecast to rise exponentially over the next 5 years – by as much as 40% depending on where you are located – Solar PV installation systems make a lot of sense.

Plus a Solar PV installation reduces your carbon emissions – The bigger the Solar PV installation system you install, the more carbon you are abating and you will increase the value of your building by improving your NABERs/Green Star rating. A well-designed system can generate more than enough energy for the business with any excess either sold back to the grid or to other tenants, if applicable, under an embedded energy network.

The other aspect of the investment is that some installations reach payback in as little as three years. Of course there are many variables in play, but even if it took seven years to break even, there is still the income stream for the balance of the projected 25 year life.

NuGreen Solutions specialist Commercial Solar team are highly experienced in designing, supplying and installing PV Solar systems from 30kW to over 1MW systems. Our in-house design team can quickly assess the suitability of your facility and area, for the provision of a Solar PV installation.

Photovoltaic Solar & Power Purchase Agreements (PPA’s)

Solar energy use in commercial buildings falls into two main categories – electricity generation and water heating.

Photovoltaic cells generate electricity when exposed to sunlight and panels of them can be placed on the external surfaces of a building to supply power. Generating energy on site means the building won’t need to use as much mains power, reducing both energy bills and greenhouse emissions.

Solar hot water systems work in a similar manner – collectors are placed on the exterior of the building and use the sun’s energy to heat water which can then be used inside the building.

The most common issue encountered in the past with solar energy systems is cost. They tended to be expensive to install, and in some cases the savings made over the system’s lifetime won’t be enough to recoup the initial investment. This has now changed and systems payback periods have been significantly reduced.

As with other options, solar energy systems require careful life cycle and cost-benefit analysis but have also reduced in price.

Power Storage Systems

Generate, store, and then use your own free power. The power storage solution is a unique battery back-up system that lets you take control of your power usage.

  • Minimise your electricity usage from the Grid
  • Instantly activate battery power when it’s needed
  • Never be exposed to short term blackouts

An exciting innovation now allows SME’s to lower their Grid Electricity usage like never before – and succeed in becoming more self sufficient.

The power storage system cleverly combines quality; roof mounted Solar Power Panels with special Australian designed Battery Back-Up. Giving you the capacity to generate, store and use free electricity at every opportunity and eliminate ever being affected by Grid blackouts. The power storage system will give your business many hours of free electricity based on the size and capacity of the battery back-up you have. And unlike a standard solar system that shuts down once the grid stops, the power storage system will utilise the power the solar panels are generating to power your business during daylight hours. The system is available as Free Standing or Wall Mounted units.

Solar Car Parks

A Solar Car Park generates electricity and shades the cars parked underneath. This increases the appeal of the establishment and its foot traffic. It is common industry knowledge that a covered car park increases foot traffic by (5) five percent through the centre or venue. Our innovative approach to funding the Solar Car Park is to use the generated electricity to pay for the entire project. When compared to Sail Shades a Solar Car Park can be $5,000 cash flow positive, over a 10 year period, per bay.

Solar Generation & Maintenance Agreement (Solar – GMA)

Conventional product delivery for a Solar PV installation is under a Capex or Financed arrangement where the installation company is paid upfront for the work and the system is signed over to the owner once it reaches practical completion. The owner then is in a position to inform the installation company when the system isn’t performing up to specification, however most owners do not have the in house capability to know when their system is performing up to specification. Hence systems tend to underperform drastically due to unrealised equipment breakdowns.

NuGreen Solutions began delivering Solar PV installations under an arrangement to address the situation where the owner and beneficiary of a Solar PV installation needs to monitor and analyse the output of the Solar PV installation. NuGreen began installing Solar PV under an arrangement where the specialists, NuGreen, are monitoring the system.

NuGreen Solutions are alerted to any equipment breakdown and are able to act with-in 48 hours. Solar PV installations with this service generate 13% more, on average, than a PV installation with regular maintenance and reporting. NuGreen Solutions Solar PV installations dramatically outperform “set and forget” installations due to the lack of equipment monitoring by experts.

Systems with the intelligence to reduce the rate you pay

Our belief is that excess power should be stored and used when it is of the most benefit to you. The price of power changes depending on the time of day you use it. The peak price times are generally when you use the most power in your business. It’s no coincidence that these price peaks clash with your businesses busy schedule.

Small Scale Wind

Some buildings incorporate wind turbines into their design to reduce the demand for mains electricity. The suitability and cost effectiveness of wind turbines will depend largely on the building’s location and typical local weather conditions.

As with solar energy systems, wind turbines can have the benefit of reducing the building’s reliance on mains electricity if implemented correctly.

On-site Generation

Cogeneration (Co-Gen)

Cogeneration plants supply both power and thermal energy using a single fuel. They run on a single fuel source, such as natural gas or diesel.

For every unit of power generated, the plant also generates two units of heat. This heat is usually wasted as exhaust in a standard electricity generation plant. But in a cogeneration plant, the heat can be used to heat the building or to provide hot water.

Cogeneration systems can be set up to serve one building or multiple buildings. They also use less water to generate power than conventional electricity generation plants.

Trigeneration (Tri-Gen)

Trigeneration systems are very similar to cogeneration systems. They can supply power and heating just like a cogeneration system, and they can also provide cooling.

In a trigeneration system, some of the generated heat is used in conjunction with an absorption chiller to supply building air conditioning systems.

Like cogeneration systems, trigeneration systems can be set up to serve one building or multiple buildings. They also use less water to generate power than conventional electricity generation plants.

Embedded Energy Networks

Embedded networks can be established where electricity infrastructure is privately owned and managed.

They have proved highly effective in shopping centres, high-rise and broad-acre residential developments and commercial/industrial parks.

Embedded networks are established to physically aggregate the energy consumed within a complex to a single metered point. Sub-meters measure tenants’ and common area consumption using the latest in smart interval metering technology.

This type of high-quality, certified sub-meter is used by local network service providers (LNSP) all around Australia, and meet the stringent metrology code imposed on all providers operating in the national electricity market (NEM).

Embedded networks commonly involve the following key participants:

    • Tenants – these consumers have selected to purchase electricity from either the embedded network or from the national market via a registered energy retailer.
    • Common Area – these meters record the energy consumed for public light and power and any mechanical services.
    • Gate Meter – one or sometimes multiple meters record the total energy consumed within the embedded network.
    • Embedded networks facilitate the energy on-selling process whereby energy is purchased at a discount at the gate meter and sold to the tenants within the network, again at a discounted rate.

 

    Technology

    Big Data

    Big data is the term for a collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications. The challenges include capture, curation, storage, search, sharing, transfer, analysis and visualization.

    The trend to larger data sets is due to the additional information derivable from analysis of a single large set of related data, as compared to separate smaller sets with the same total amount of data, allowing correlations to be found to “spot business trends, determine quality of research, assess energy consumption patterns, and identify errors and faults.

    In the energy efficiency sector being able to capture and analyse data can assist in improving an asset or property portfolio performance. Monitoring and reporting is they way in which NuGreen can take big data and make it work for our clients.

    Monitoring & Reporting

    NuGreen can provide sub-metering and energy metering systems that have the ability to continuously monitor the energy consumption associated with a site. The technology platform comprises of micro current transformers installed on circuits and sub meters which are used to monitor energy consumption, using newly developed din rail mounted energy monitoring units.

    Ease of Installation and Integration:

    These units are wholly Australian made and able to be installed at the sub-circuit level using micro current transformers which avoids the need to perform any distribution board modifications. The energy monitoring units connect to an internet access portal unit which allows direct internet access to the energy consumption data.

    Energy monitoring units will be installed into small enclosures which will be mounted adjacent to each distribution board.

    Monitor Real Time:

    The distinct advantage that this monitoring system can offer is the ability to install the system without any changes to the existing distribution boards. This is a significant advantage in any retrofit project as it enables the accurate reading of energy consumption without the additional cost that incurred by distribution board changes.

    Clients are able to monitor energy consumption associated with the change to energy for the buildings via the internet – on a web based interface on a real time basis. This will then allow the identification of trends and areas of the buildings that are consuming the most energy. The system has parameters that can be set to facilitate email notifications at variable intervals along with the graphical dashboard display, which allows records and all the data to be downloaded from the web page.

    Functionality:

    This system has been developed specifically for retrofit projects such as proposed lighting upgrades. NuGreen can install a trial unit immediately upon engagement to demonstrate the system functionality.

    Automation

    Intelligent Building Platforms helps owners; operators and occupants of buildings understand and control operational costs. Property owners and operators are struggling to get an individual asset or portfolio view of operational data from multiple buildings and a variety of systems.

    HVAC & Controls

    Building Management Systems (BMS)

    Building management systems are central computerised systems used to manage a building’s operation.

    Systems that may be connected to a building management system include heating, ventilation, air conditioning, lighting, security, fire services, plumbing and building access. A building management system can contribute to reductions in energy usage by automatically adjusting a building’s systems, turning them off when they are not required or optimising their running cycles.

    Chillers & Boilers

    HVAC systems are the greatest energy consumers in most commercial buildings, and most of these air conditioning systems vary according to the application, but they all have similar attributes.

    Outside of a good control automation system, the chiller, boiler and motors have the greatest potential to capitalize on energy efficiency and offer the best return on investment.

    Generally, chillers are the primary consumer of energy in most building systems. So, even small changes in operating efficiency can affect energy costs. Chillers are typically meant to carry the largest cooling load during an ordinary year in the facility, even though that load may only happen for a few hours. For the remainder of the time, the chiller system works at a lesser load, occasionally an even greatly reduced load.

    Unfortunately, chillers run at their highest efficiency when they run at or near full-load settings. So, as the load on the chiller declines, the efficiency of the chiller also declines.

    Combustion efficiency for air and fuel mixtures is vital to proper boiler operation. Too much oxygen reduces the operating efficiency of the boiler and causes undesirable pollutants.

    Likewise, too little oxygen will result in fuel not completely combusting and will create a build-up of soot, clogging surfaces and reducing boiler efficiency. Therefore, some excess oxygen is necessary to ensure complete combustion and prevent damage from soot build-up.

    Fine-tuning the boiler’s combustion controls will limit the excess air introduced into the boiler and, consequently, increase its periodic operating efficiency.

    AHU

    An air handler, or air handling unit (often abbreviated to AHU), is a device used to condition and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. Usually, an air handler is a large metal box containing a blower, heating and/or cooling elements filter racks or chambers, sound attenuators, and dampers. Air handlers usually connect to ductwork that distributes the conditioned air through the building, and returns it to the AHU. Sometimes AHUs discharge (supply) and admit (return) air directly to and from the space served, without ductwork.

    As part of the HVAC system, AHU’s and Air Extraction units are also consumers of energy and part of the NuGreen audit process we assess the load they use in undertaking their function.

    Variable Speed Drives (VSD)

    Traditionally, air conditioning system components such as fans and pumps have used constant speed drives (motors) – they operate at a fixed speed and can only be switched on or off.

    Variable speed drives allow these components to modify the speed they operate at to better match the load that is being put on them. This can allow for significant energy savings, depending on the system. Variable speed drives also tend to require less maintenance as their ‘soft start’ capability reduces start up wear compared to fixed speed drives.

    Variable speed drives aren’t necessarily a direct replacement for fixed speed drives though. System changes will probably be required to allow variable speed drives to be used and realise their full potential, as changing one or more drives from fixed to variable speed will have an effect on other system components and efficiencies.

    Controls

    Direct Digital Controls – Central controllers and most terminal unit controllers are programmable, meaning the direct digital control program code may be customized for the intended use. The program features include time schedules, setpoints, controllers, logic, timers, trend logs, and alarms.

    The unit controllers typically have analog and digital inputs that allow measurement of the variable (temperature, humidity, or pressure) and analog and digital outputs for control of the transport medium (hot/cold water and/or steam). Digital inputs are typically (dry) contacts from a control device, and analog inputs are typically a voltage or current measurement from a variable (temperature, humidity, velocity, or pressure) sensing device. Digital outputs are typically relay contacts used to start and stop equipment, and analog outputs are typically voltage or current signals to control the movement of the medium (air/water/steam) control devices such as valves, dampers, and motors.

    Groups of DDC controllers, networked or not, form a layer of system themselves. This “subsystem” is vital to the performance and basic operation of the overall HVAC system. The DDC system is the “brain” of the HVAC system. It dictates the position of every damper and valve in a system. It determines which fans, pumps, and chiller run and at what speed or capacity. With this configurable intelligence in this “brain”, we are moving to the concept of building automation.

    More complex HVAC systems can interface to Building Automation System (BAS) to allow the building owners to have more control over the heating or cooling units. The building owner can monitor the system and respond to alarms generated by the system from local or remote locations. The system can be scheduled for occupancy or the configuration can be changed from the BAS. Sometimes the BAS is directly controlling the HVAC components. Depending on the BAS different interfaces can be used.

    NuGreen Solutions provide a number of services which can improve the energy efficiency of a building by better managing and optimising the controls and BMS of a facility.

    Tuning & Commissioning

    Optimisation of energy saving features and ensuring safe operation of a new facility requires a combination of good design, quality installation, thorough commissioning and ongoing tuning of operating systems. Often commissioning quality is adversely aff¬ected by construction program pressures and shortfalls in understanding the integrated function of systems.

    Recommissioning occurs when a building that has already been commissioned undergoes another commissioning process using the same tests used in the original commissioning process.

    Recommissioning of existing buildings is undertaken with the aim to improve the performance of building services and energy efficiency.

    Recommissioning is made easier if existing commissioning data and operations and maintenance manuals are made available to commissioning staff¬. This information provides an overview of the systems, relative performance benchmarks, how they have performed in the past and what systems have been modified.

    NuGreen has in-house commissioning and building tuning teams that undertake full tuning and commissioning as part of the implementation phase of a project.
