Important Facts

Under the Kyoto Protocol overall reductionfor CO2 emissions needs to fall by 20% by2020.

Up to 50% of CO2 emissions related to

residential and commercial buildings is fromelectricity consumption.

If newly constructed buildings performexactly as existing buildings the result by2020 will be an increase in electricityconsumption of 22%.

Important Facts

In order to reach a fall in consumption of20% by 2020 the following has to happen:

1- All new buildings constructed toconsume 50% less energy

2- 1 in 10 existing buildings to reduceconsumption by 30% each year

The ability to meet targets by simply

persuading people to act differently ordeploy new energy saving or energy efficienttechnology is unlikely to succeed.

Important Concepts

Power is nothing without control. If you cant measure it, you cant monitor it.

If you cant monitor it , you cant control it.

If you cant control it, you cant manage it. Management & Control is the KEY to energy

Efficiency

It will cost a lot less to save energy for the

future rather than investing in renewableenergy

BMS Role in DeliveringEnergy Efficiency

Energy represents the single largestcontrollable operating expense for officebuildings, typically contributing as much as a

third of a buildings variable expenses.

Only 10% of commercial buildings have aBMS installed

Less than 10% of commercial buildings haveautomated lighting control

BMS can save energy through a variety ofmethods, including:

1- Reduction of Equipment Runtime2- Efficient Unloading of Equipment

3- Automated Fault Detection

4- Monitoring & Targeting

5- Load Shedding

BMS Role in DeliveringWater Efficiency


8/6/2019 01 Bas & Green Gt2

15/46


BMS can deliver building water efficiency intwo main areas:-

1- Landscape Irrigation.2- Water Leak Detection

8/6/2019 01 Bas & Green Gt2

16/46


BMS can control Landscape Irrigation in thefollowing ways:-

1- Open/Close valves for a set duration for aset number of periods per week anddepending on the time of the day and theweather conditions

2- Adding Moisture Sensors

8/6/2019 01 Bas & Green Gt2

17/46


BMS can monitor if there are water leaks inthe building in the following ways:-

1- Installing Water Leak Detectors

2- Monitoring the Water pressure in closedloop hydronic systems

3- Monitoring Water Tanks levels so that

overflow does not occur4- Monitoring the characteristics of

Wastewater treatment plants

BMS Role in DeliveringIEQ

BMS Role in Delivering IEQ(Indoor Environment Quality)

8/6/2019 01 Bas & Green Gt2

19/46


Factors regulated by BMS that impact IEQinclude operative temperature, relativehumidity, outdoor air flow rates and light

levels. They can be categorized as follows:-

1- Thermal Comfort

2- Air Quality and Ventilation

2- Lighting Levels

8/6/2019 01 Bas & Green Gt2

20/46


1- Thermal ComfortThermal comfort for a person is the

combination of proper temperature andproper relative humidity levels

BMS Plays a major role in maintaining thethermal comfort conditions at acceptablelevels

Typically 22-24 C and 40-60% RHo

8/6/2019 01 Bas & Green Gt2

21/46


2- Air Quality and VentilationBMS plays an important role in ensuring

that minimum outdoor airflow rates areachieved in three areas:-

1- VAV System Control

2- Mixed-Mode Ventilation Systems

3- Dynamic Reset of Outdoor Air IntakeFlows

8/6/2019 01 Bas & Green Gt2

22/46


3- Lighting LevelsBMS can maintain desired light levels by

either adjusting electric light output orcontrolling the amount of daylight enteringthe building by the following:-

23/46


3- Lighting Levels - continued

a- Measuring Light levels inside the space bythe use of Photocells

b- Brighten or Dim the lights

c- Switch between multiple light levels

d- Raise or Lower window Blinds or adjust

louvers to keep daylighting at comfortablelevels and eliminate glare

BMS CommissioningProcess

BMS Commissioning Process

8/6/2019 01 Bas & Green Gt2

25/46


BMS commissioning process is defined as:

A quality focused process for enhancing the

delivery of a project. The process focusesupon verifying and documenting that thefacility and all of its systems andassemblies are planned, designed,

installed, tested, operated and maintainedto meet the owners project requirements

8/6/2019 01 Bas & Green Gt2

26/46


The design engineer should focus on thefollowing points to facilitate a successfulcommissioning program

1- Include the Commissioning provider in thedesign stage

2- Provide detailed control descriptions

3- Provide detailed control sequences
