Building Management Systems provides its energy conservation solution in the most economical and timely mannerpossible, with minimal interruption to the on-going business and the occupants of the Facility.

The Work consists of three Phases as follows:

Phase 1 - System status review:

For existing buildings:Building Management Systems will perform a Technical Energy Audit and Project Development Plan:Building Management Systems will at this stage review the current system status based on:· As-built documentation provided by Client· Consumption details for several months (DEWA bills) provided by Client· Site inspections

Building Management Systems will analyze the system energy efficiency and provide a list of recommended measuresto improve it. If the estimated system energy efficiency proves to allow for considerable energy savings, BMS will thenforward a proposal for its energy saving programme

For new buildings:Building Management Systems will study the project and propose energy efficient control solutions in coordination withthe Engineering Consultant and MEP Contractor.

Phase 2 - Design and implementation

For existing buildings:Building Management Systems will manage, design, construct, and commission the project defined in Phase 1, ProjectDevelopment Plan approved by the Owner, and will provide training to Facility Maintenance and operations staff regardingproper use and maintenance of the designed system.

Building Management Systems will prepare a detailed contract that will specify programme implementation details, its costand duration, scope of work, responsibilities and obligations for both parties, reference values for energy saving calculationand the actual savings calculation method, guaranteed savings, payment schedule etc.

Upon signing the contract, BMS will undertake the implementation of the programme. This includes full design of the energyconservation system, supply and installation of all necessary equipment, system testing, commissioning and start-up,verifying energy savings upon system start-up in consequent months

For new buildings:Building Management Systems will manage, design, construct, and commission the project in coordination with theConsultant and MEP Contractor, and will provide training to Facility Maintenance and operations staff regarding properuse and maintenance of the designed system.

Building Management Systems will provide full design of the energy conservation system, supply and installation of allnecessary equipment, system testing, commissioning and start-up.

Phase 3 - Warranty and maintenance

Building Management Systems will perform all functions necessary to measure, verify, and achieve the Guaranteed EnergySavings. Building Management Systems will perform system fine-tuning for optimum performance and will monitor thesystem operation (remotely and by visits) during the contract period

Building Management Systems can also provide remote operation and maintenance contract upon expiry of the originalcontract.

Chiller Plant Optimization involves theimprovement of the operational eficiency of thetotal plant consisting of chillers, cooling tower,condenser water pumps and chilled water pumps.Its specialized control algoritms provide:

Energy saving.Increase of the system flexibility.Extended chiller plant life, due to reducedoperating hoursProvides spare capacity for future expansionof the facility.Lower maintenance cost due to reducedoperationg hours.

Expected energy saving: 20-30%, withoutcompromising the environmental comfort.

Improves facility operation due to full automationof the plant.Improves the facility maintenance due to earlyindication/warning of any faults or failures. Thefaults can be rectified even before it becomesproblematic.

The Universal Chiller Plant Control Solution (CPCS) from Matrix Controls is an application specific LonWorks DDC basedsystem for capacity and lead/lag control of a group of chillers and necessary peripheral equipment. The system is piecedtogether using specific interactive modules, one for each type of equipment that makes up a chiller plant, and together withduty coordinating modules and a capacity commander module, is able to sequence all related equipment for the properfunctioning of the chiller.

FEATURES

CPCS automatically calculates cooling demand from supply/return temperature and the flow rate of chilled water to decidethe number of chillers to switch on or off.

determines next available chiller, pump and cooling tower to turn on or off in sequence to maintain equal running hoursand even wear & tear of each piece of equipment.

modulates bypass valve to maintain differential pressure across supply and return headers. System also works with de-coupling systems without bypass valves.

eliminates single point failures by having distributed intelligence- each piece of equipment is assigned one DDC- ensuringreliable chiller plant control.

automatically avoids activating faulty equipment, relying on serviceable equipment to meet calculated cooling demand.

suitable for all chiller plants piped in common header pipe configuration, even when of quantity of chillers, cooling towersand water pumps are not equal in number (e.g.: in plants with extra standby pumps and or cooling towers)

1 - conserving energy on production level

Incoming and outgoing airflows pass through differentsides of the cube-shaped transfer unit, (though airflowsare not mixed). This system contains fans for both freshair and exhaust air.

Efficiency: 70-80%

Advantages:Low maintenance costs.No cross contamination.Reasonable level of investment.Low-pressure drop.

The loop connects with a finned-tube coil in the exhaust plenum,and with a finned-tube coil in the AHU.

Efficiency: 45-60%

Advantages:Easy installation (exhaust and fresh ducts shouldnít beclose to each other).System can cover more than two ductsLow investment.Low energy consumption (pump).Low maintenance costs.No cross-link contamination.No mechanical initializing parts (except the circulationpump).Low-pressure drop.

Advantages:No additional energy required.No maintenance (just cleaning).No cross-link contamination.Low-pressure drop.Operation without additional device.Low investment.

Heat Pipes

Run Around Coils

Heat/Energy Recovery Ventilators

Variable static pressure regulator Optimises air distribution in Variable Air Volume (VAV) AHUsystems thus greatly reducing energy usage. This is achievedby continually adjusting static air pressure set-points of anAHU as opposed to conventional VAV AHU systems whichrely on a fixed static air pressure set-point.

Expected energy saving: 50%, without compromising theenvironmental comfort.

Key Advantages

AHU fan runs at lower average speeds resulting in moreenergy savings

Individual VAV boxes (up to 25 VAV boxes under one controller)receive just enough cooling air flow resulting in more effectivecooling in individual roomsCooling demand is met more quickly and efficientlyRequires no modification of existing hardware beyondinstallation of the Variable Pressure RegulatorSmall dimensions - easy panel mount installation.Huge energy savings at low installation cost

2 - conserving energy on distribution level

Self-recycling loop coils with easy evaporated liquid.

Efficiency: 60-70%

Using a whole bundle of partial functions, room automation automatically reduces heating, cooling or electrical powerrequirements as a function of the room utilization and the free energy sources available, such as sunlight or cool night air,to a minimum. In this way energy and cost savings of up to 50% can be made.

In contrast to conventional DDC control system, that typically controls production and distribution of energy,room automation is concerned with optimizing the energy consumption on the emmission side in individualrooms - at the end user location. It is possible to see that the biggest savings can be made if one first avoidsuncalled-for energy consumption in the rooms themselves. Only room automation is able to decide whethera light should still be left on after sunrise or whether a radiator should be turned off, because a window hasbeen opened to air the room. In this way, room automation is the most important tool in improving energyperformance!

Room automation provides:

40% of heating and cooling energy and60% of lighting energy

can be saved by:

optimum use of daylighttime program-controlled switching of mode change-overblocking the energy supply when opening windowscooling through windows during the nightoccupancy sensors

Room automation, therefore, reduces primary energy consumptionby up to 50 per cent, thus halving your energy costs. Therefore,efficiency-improving room automation is not just beneficial to theenvironment but is also a high-return investment.
