commissioned according to ASHRAE Guideline 0-

2005 to verify that the HVAC systems achieve the

owner’s project requirements. The Commissioning

Process will be used to achieve, verify, and

document the performance of facilities, systems,

and assemblies to ensure that they meet definedobjectives and criteria

An independent GBI recognized commissioning

specialist will be appointed at the onset of the

design process to verify that comprehensive pre-

EQ2 – Environmental Tobacco Smoke (ETS) Control

•Prohibit smoking in the building, provide no smoking signage in the building•Locate exterior designated smoking areas at least 10 m away from entries,outdoor air intake or operable windows




Q

EQ3 – Carbon Dioxide Monitoring and Control

• To ensure good indoor air quality, Code of Practice on “Indoor Air Quality 2005” will be adopted

• The amount of CO2 will not exceed C1000 ppm for an eight-hours time-weighted average

• Demand Control Ventilation system will be installed to reduceenergy consumption when there is low level occupancy

• CO2 sensors will be installed at all main return points on each

floor for continuous monitoring

Damper Actuator

DDC

CO2 Sensor




EQ4 – Indoor Air Pollutants

•Provision to use low VOC paint and coating, carpet or flooring

throughout the building and encourage to use low VOC adhesive and

sealant•Use product with no added urea formaldehyde.




EQ5 – Mould Prevention

Architectural Component

• To prevent rainwater leakage through r c. roof

– Ensure proper roof detailing and construction– Specifies appropriate waterproofing membrane

– Ensure waterproofing is applied by specialist with warranty

– Recommend waterproofing admixture to be added to theconcrete flat roof as additional measure

– Ensure the surface to receive waterproofing membrane is

properly prepared (i.e. no depression to avoid ponding and allcracks are sealed and rectified before application of waterproofing membrane. Ponding test to be carried out to testthe integrity of the roof before and after application of waterproofing

– constant inspection to be carried out at the roof soffit to detectany sign of leakage during occupancy

• To prevent water leakage through walls– Ensure proper construction of the walls to prevent water

seepage by minimizing cracks and porosity of wall such as:

• To ensure the walls are constructed with quality bricksthat comply with minimum compressive strength




EQ5 – Mould Prevention

• To prevent water leakage through walls (cont)

• Ensure the brick walls are properly dubbed and filled

with cement mortar before plastering• Ensure adequate bonding ties are provided for

brickwork construction

• To ensure the plaster composition and thickness arecorrect

• To wet the walls before plastering to minimize

shrinkage cracks• Ensure junction of windows/openings and walls are

properly sealed

• To prevent leakage through floors especially at toilet areasand areas exposed to weather

– To provide waterproofing to all the wet areas

– To ensure waterproofing is applied correctly by thespecialist




EQ6 – Thermal Comfort

• Two design parameters to be considered are;

– Relevant design temperatures as per AHSRAE 55/MS1525

– Air velocity in the region of 0.15 m/s to 5.5 m/s




EQ6 – Thermal Comfort

• Comfort controls for occupants considered;

– Zoning of perimeter due to higher radiant heat through

windows

– Apply VAV system according to different zoning

– Limit of VAV airflow to meet design noise level

– Room thermostat to be located at strategic locations within each zone to achieve comfort conditions

VAV Box




EQ8 – Daylighting

•Provide 30% of the NLA has a daylight factor of 1.0% - 3.5%




EQ9 – Daylight Glare Control

• Eliminate glare from: Direct SUNLIGHT and maintain workspace LUX less than 2,000

• Diffuse SUNLIGHT for occupant-workspace at viewing angles of 15° to 60° from thehorizontal at eye level

• Manual roller blinds will be adopted




EQ10 – Electric Lighting Levels

• Design lighting level comply with MS 1525

• Lighting lux level simulated

with appropriate software




EQ11 – High Frequency Ballasts

• High frequency ballasts will be used for all fluorescentlamps

• The primary advantage of high-frequency fluorescentlighting is the improvement of efficacy relative tolighting systems with 60Hz magnetic ballast

• High-frequency operation also reduces the possibilityof perceptible lamp flicker that is sometimes

associated with low-frequency ballast, as the lampphosphors are refreshed more often




EQ12 – External Views

• Allows more than 60% of the NLA has external views through windows

• Open Plan Concept will be adopted• Meeting rooms , store and archive rooms will be located away from

windows

• Low cubicle partition vision glass panels will be used

• Purpose is to create a pleasant working environment thus higher work productivity




EQ13 – Internal Noise Levels

• Establish noise

criteria dependingon space usage

• Minimize noise from building services

• Also consider noise

breakout from othersources

EQ15 – Post Occupancy Survey : Verification

• A post-occupancy comfort survey of building occupants will be conducted within 12 months after occupancy/building

completion. The survey will be collected by a neutral thirdparty and respondents are to be remained anonymous.

• Measured data will be compared to ASHRAE STD 62.1-2007, STD 55-2004, MS 1525-2007 and Code of Practice onIndoor Air Quality 2005

• The survey will cover the following:

– Lighting comfort

– Temperature comfort

A. Conservation

On previously developed or graded site, restore or protect a minimum

of 50% of the site area (excluding the building footprint) with native or

adaptive vegetation. Native or adaptive plants are plants indigenous

to a locality or cultivars of native plants that are adapted to the local

climate and are not considered invasive species or noxious weeds.

Applicable to landscaping on rooftops and roof gardens so long as the

plans meet the definition of native or adaptive vegetation. Total Site Area = 12,046 m2

Building Footprint = 3,334 m2

Balance area = 8,712m2

50% of balance area = 8,712/ 2 = 4,356m2

During Construction, disruption to the natural hydrology will occur and they can

be mitigated by due diligence site planning and storm water design and with theprovision of :

● Implement an Erosion & Sediment Control (ESC) Plan

● Proper site management of surface water run-off treatment.

● Increasing or improving ground surface infiltration.

● Elimination of contamination sources.● Proper handling of contaminants and disposal.

● Removing pollutants from storm water run-off.

● Provision of silt-traps prior to final discharge to exist drains and waterways.

STRATEGYTo recover condensate water into a/c make up tank

Condensate water recovery (accounting for at least 50% of total

AHUs/FCUs for use as cooling tower make up water etc

Estimation of Condensate water generation.

Latent heat = mass of water x heat of vaporisation

H = m x L

Base on 1445kW(411RT) cooling load, 20% goes to latent heat.

The heat of vaporisation is 2438kJ/kg, to condense vapor into

water.

Hence, the generated condensate water is estimated to be

Q (l/s) = 1445kW x 0.20 / 2438kJ/kg x 1 L/kg = 0.12 L/s

Daily condensate water generation = 0.12 L/s x 3600 s/hrs x 10

hrs/day x 0.8DF = 3456 Liter/day (3.5m3/day)
