• Police the accuracy and appropriateness of submission • Provide advices to client on green senses. Content of this talk: • Philosophy • physiological responses • IEQ integration • IEQ measurement • BEAM Plus IEQ overview • BEAM Plus credit assessment examples
IEQ Philosophy: Micro view: human physiology on responses to the
four basic IEQ qualifiers – thermal comfort, indoor air quality comfort, visual comfort and aural comfort.
Macro view: integrated responses to the total IEQ comfort and protection against infection of communicable disease.
Comprehensive view: total quality consideration. Harmonization of green components and optimization of system design, installation, operation and maintenance.
The overall sense and perception to the indoor environment.
The sensory system of our human body is very complex…
But, briefly speaking, How many senses?
Aural
Visual
Olfaction: IAQ
4 basic factors:
Visual comfort
Aural comfort
Indoor Air Quality
Thermal comfort
Distinguish between discomfort vs. health hazard
Discomfort (examples) Health Hazard
Thermal Warm / cool sensation Heat stress, Cold stress
IAQ Odour Inhalation of toxic gases
Visual Glare, Eye strains Retina damages due to blue-light hazard: Excessive illumination with blue light or UV radiation
Aural Noise annoyance Hearing damages
Normally, IEQ problem in built environment would not lead to hazardous level, although sick symptoms may be reported.
Thermal receptors are free nerve endings detecting temperature changes
3 types of receptors: 1. Warm receptors 2. Cold receptors 3. Pain receptors (detect temperature extremes) Different number of receptors at different part of the body
Impulse discharge frequency
ASHRAE standard 55 defines Thermal comfort as ◦ That condition of mind that expresses satisfaction
with the thermal environment
Thermal comfort 90 equations and 138 parameters

Nose To: Respiratory Tract Air in
Olfactory system in our brain
The odorant stimulate the olfactory cell.
Signal transmission through olfactory nerve.
Air in which there are no known contaminants at harmful concentrations as determined by cognizant authorities and with which a substantial majority (80% or more) of the people exposed do not express dissatisfaction.
Three Levels of IAQ
Comfortable IAQ Healthy IAQ Safe IAQ
IAQ Guidelines
Comfort criteria : Local – • Guidance Notes for the Management of IAQ in Offices and Public Places (Excellent Glass) – EPD
Perception of comfortable IAQ is detected by the nasal sense as odour
• Comfortable IAQ does not imply a healthy and safe IAQ
• Uncomfortable IAQ does not necessarily imply unhealthy or
unsafe IAQ
• Comfortable IAQ is achievable by adequate ventilation of fresh air to dilute human odour
• Fresh air is defined as air quality at or better than that set out in Hong Kong outdoor air quality objectives
Healthy IAQ refers to air quality in which concentration of all the air constituents are within the safe limits as recommended by cognizant authorities.
Health criteria - Local : ◦ Reference Note on Occupational Exposure Limits
(OEL) for Chemical Substances in the Work Environment – Labour Department ◦ Guidance Notes for the Management of IAQ in
Offices and Public Places (Good Class) – EPD
Recommended IAQ Objectives for Office Buildings and Public Places [GN 2003, Hong Kong]
Parameter Unit 8-hr average
Excellent Good Carbon Dioxide ppm < 800 < 1000
Carbon Monoxide µg/m3 < 2000 < 10000 Respirable Suspended Particulates µg/m3 < 20 < 180
Nitrogen Dioxide µg/m3 < 40 < 150 Ozone µg/m3 < 50 < 120
Formaldehyde µg/m3 < 30 < 100 Total Volatile Organic Compounds µg/m3 < 200 < 600
Radon Bq/m3 < 150 < 200 Airborne Bacteria cfu/m3 < 500 < 1000
Room Temperature oC 20 – 25.5 < 25.5 Relative Humidity % 40 – 70 < 70
Air Movement m/s < 0.2 < 0.3
A safe IAQ is indoor air containing no pathogenic or infective micro-organisms such as fungi, bacteria or viruses.
As reference, a doctor in US in 1893 had used ventilation rate of 28 L/s/person to avoid cross infection of tuberculosis.

Retina: The light receiver
Adaptation of various illumination level: Step 1: Constriction or dilation of iris. Step 2: Neural adaption at retina Step 3: Photochemical adaption at retina
Image formation
Signal transmission from photoreceptor to optic nerve
Factors relating to quantity include:
Illuminance: the amount of light reaching a surface (i.e. the light level)
Distribution of light: luminaire type, spacing and layout. Background lighting and task lighting
Factors relating to quality include:
Colour: Colour of light and the colour rendering (i.e. how colours appear in that light.
Contrast: to allow task detail to be clearly and comfortably seen
CSP index Predicted from glare index, illuminance and colour rendering.
Visual Comfort Probability
Developed to address discomfort glare.
In this model, the Discomfort Glare Rating is converted to the probability that a population of viewers will consider the sensation is acceptable.
Example: a luminaire with a VCP of 70 will produce acceptable
glare sensations in 70% of the population. A luminaire with VCP of 70 is
considered as acceptable.
Markers of visual discomfort: Manifestation of sick symptoms such as:
Red / sore/ itchy or watering eyes Headaches Difficult to concentrate
(There can be many other causes of these symptoms, such as
exposure to irritants or indoor air pollutant at the eye)
1. Pinna & Ear canal help to amplify sound by as much as 20 dB over a broad range of frequency centered around 4 kHz
2. Airborne sound waves in ear canal strike the tympanic membrane and set it into motion.
3. The ossicles transmit the motion (at tympanic membrane) to inner ear
4. Sound wave reaches the inner ear sets the Basilar membrane & organ of Corti into motion.
4. Sound wave reaches the inner ear sets the Basilar membrane & organ of Corti into motion.
5. The amplitude of vibration along the Basilar membrane is a function of the frequency of sound.
6. Inner hair cells at the organ of Corti carry the bulk information from inner ear to the brain through the afferent axons to the auditory (Cochlear) nerve.
7. Outer hair cells at the organ of Corti receive axonal terminals from neurons lie in the brain.
Noise Assessment
Room Reverberation
Speech Interference
Speech Transmission
Speech Intelligibility
Noise Criterion (NC) curves developed by Beranek.
When a number of NC (e.g. NC40) is chosen, it defines the maximum allowable sound level at all octave bands centered at 63 Hz to 8000 Hz.
Reverberation time (T60) is controlled in interior building spaces to enhance speech intelligibility or enhance music quality. It is the time it takes for sound to decay by 60dBA.

IEQ P1 MINIMUM VENTILATION PERFORMANCE
5.9.2 Exfiltration. For a building, the ventilation system(s) shall be designed to ensure that the minimum outdoor air intake exceeds the maximum exhaust airflow whenever the mechanical air-conditioning systems are dehumidifying.
Exception: Where excess exhaust is required by process considerations and approved by the authority having jurisdiction, such as in certain industrial facilities.
Note: Although individual zones within a building may be neutral or negative with respect to outdoors or to other zones, net positive mechanical intake airflow for the building as a whole reduces infiltration of untreated outdoor air.
ASHRAE 62.1 - 2010
63
IEQ P1 MINIMUM VENTILATION PERFORMANCE ASHRAE 62.1 - 2010
6.2.1 Outdoor Air Treatment. If outdoor air is judged to be unacceptable in accordance with Section 4.1, each ventilation system that provides outdoor air through a supply fan shall comply with the following sections.
Exception: Systems supplying air for enclosed parking garages, warehouses, storage rooms, janitor’s closets, trash rooms, recycling areas, shipping/receiving/distribution areas.
Note: Occupied spaces ventilated with outdoor air that is judged to be unacceptable are subject to reduced air quality when outdoor air is not cleaned prior to introduction to the occupied spaces. Local statutes relevant to Hong Kong concerning outdoor air quality shall be followed.
64
5.9.1 Relative Humidity. Occupied space relative humidity shall be limited to 65% or less when system performance is analyzed with outdoor air at the dehumidification design condition (that is, design dew point and mean coincident drybulb temperatures) and with the space interior loads (both sensible and latent) at cooling design values and space solar loads at zero.
Note: System configuration and/or climatic conditions may adequately limit space relative humidity at these conditions without additional humidity-control devices. The specified conditions challenge the system dehumidification performance with high outdoor latent load and low space sensible heat ratio.
Exception: Spaces where process or occupancy requirements dictate higher humidity conditions, such as kitchens, hot tub rooms that contain heated standing water, refrigerated or frozen storage rooms and ice rinks, and/ or spaces designed and constructed to manage moisture, such as shower rooms, pools, and spas.
