Carbon Emissions from Buildings

40%


Up to 50% of energy used in a building is wasted due to inefficient power, lighting and HVAC infrastructure

Wastage!!!!

Improve Project Completion


The American Society of Heating,Refrigeration and Air-Conditioning Engineers(ASHRAE) Guideline 202-2013:

Commissioning Process for Buildings andSystems, defines commissioning as a “Qualityfocused process for achieving, verifying anddocumenting that the performance offacilities, systems and assemblies meetsdefined objectives and criteria”.

Commissioning is multi discipline and can beconsidered a bridge between the design anddelivery of a project. The more complex andinterconnect the systems or building thegreater the need for commissioning.

The Reality of Construction


The Commissioning & Close-Out ScheduleIt’s all about the detail


Commissioning – The Testing Sequence

Generally Contractor Testing Activities, and CxA Verifications proceed from the lower to the higher levels of complexity as follows:

o Static tests (such as duct leakage, Pipework pressure testing)

o Completion of construction check sheetso Start-upo Control point to point checkso Balancingo Completion of start-up check sheetso Systems functional test procedureso Intersystem functional test procedureso Integrated Building Testso Seasonal Performance Testing

TYPICAL AIR HANDLING UNIT COMMISSIONING PROCESS DIAGRAM


The Usual Approach to Scheduling

• Is overly ambitious• Is uncoordinated with Installation

Schedule• Risks destroying previous efforts• Risks offering poor installation quality• Risks project overrun• Is detrimental to building operational

performance


The Usual Approach to Scheduling Building Commissioning


Commissioning – The Devil is in the Detail


The Overall Commissioning Schedule

• Co-ordinated with the overall construction schedule

• Prepared as early as possible

• Used for monitoring & reporting commissioning progress and ultimately progress payment.


Final Thought on Scheduling


Project Handover - The Current Situation


Why Not Go Fully Digital????

Into the 21st Century

Closing Remarks


Construction Needs a Paradigm Shift


Owners are Looking for Change

• Too many claims at the end of the project• Too many change orders• Contract documents not well coordinated• Poor Scheduling• Dissatisfaction with project outcomes

o M & E systems inefficiento Lowest bid vs desired outcomeo Lack of cohesion within team

“the surgery was a success but the patient still died!!!”


Is That ChangeCommissioning Management?

Commissioning Management ensures a planned, programmed, auditable and structured approach to the commissioning process is carried out to the highest standards… It makes sure your systems and building works from Day One.


Commissioning High Performance Buildings

Efficient HVAC Equipment & Controls

• Functional testing• Direct observation(e.g. schedules, thermal overlap of systems, time schedules etc.• Equipment oversizing

Efficient Windows, Insulation & Other Envelope Components

• Verify Materials & Installation matches design intent

• Design & application to ensure avoidance of moisture and thermal comfort problems

Design/Construction/Startup• Develop & adhere to OPR• Submittal Reviews• Equipment Sizing, thermal

distribution, system optimization• Scheduling• Construction Observation• Training

Sensors for Control• Calibration/Accuracy• Correct Placement• Proper alignment with BAS/EMS

Efficient Lighting Equipment & Controls

• Verify installed equipment is as per OPR/BoD

• Controls, sensors, algorithms are functioning correctly

• Light level is appropriate for task

Metering: Energy Management System: Metering System

• Correct and Optimal application of tools

• Test & Verify that systems display and match

• Trending and benchmarking of information

• Use of third party software for analysis and optimization of building operation

Geothermal Systems • Accurate hydronic balancing• Functional testing• May require operation through 4

seasons to optimize output
