INDOOR ENVIRONMENTAL QUALITY (IEQ) IN OFFICE/HEALTHCARE

• Indoor Environmental Quality refers to:

The state of the air and environment that contribute to the health and comfort of occupants inside the buildings.

SICK BUILDING SYNDROME

• Sick building syndrome (SBS) is the name used to describe a situation whereby the occupants of a building experience acute health or comfort related effects that seems to be linked directly to the time spent in the building.

The symptoms of SBS may include:• Headache• Nausea • Aches and pains• Fatigue

SICK BUILDING SYNDROME

• Poor concentration• Shortness of breath• Eye and throat irritation• Irritated, blocked or runny nose• Skin irritation

INTEGRATIVE DESIGN PROCESS

A combined IEQ team can

involve these profession with an aim which is to maximize the

comfort and health for occupants.

IEQ MANAGEMENT PLAN

An IEQ management plan should:- • Include strategies to maintain air quality during

construction or renovation projects.• Integrate a green cleaning and integrated pest

management programme.• Incorporates occupant feedback for continuous

evaluation.

BASIC INSTALLATION PROCEDURES

1. Dismantle and haul away existing air conditioner materials, and clear all related debris before starting the new install.

2. Acquire proper permits and schedule required inspections from the city where we live.

3. Install new ductwork (if indicated in proposal), or prepare existing ductwork for use with the new system. 

4. Properly position and place outdoor air conditioning unit.

BASIC INSTALLATION PROCEDURES

5. Make proper and safe connections and determine the correct sizing for the electrical and refrigeration lines and piping.

6. Install a new thermostat or reuse the existing thermostat. 

7. Charge and start the new system according to manufacturer specifications.

8. Conduct a post-installation check or inspection before final inspection.

CHOOSING THE RIGHT AIR CONDITIONING SYSTEM

• Split Systems

Commonly used ventilation system

A split framework is an air-conditioning or warmth pump framework that utilizations refrigerant as the warmth trade liquid and has an evaporator, compressor, and condenser as independent parts.

• Packaged Units

A package unit is the all-in-one heating and cooling system for homes that don't have a lot of room indoors for either a furnace and coil, or an air handler. 

Package units will contain all of their parts in one outdoor unit that sits on either the roof or to the side of a building.

CHOOSING THE RIGHT AIR CONDITIONING SYSTEM

ADVANTAGES OF IEQ

• Increase comfort• Decrease absence rates• Increase work performance• Pollutant inside building can be diminished• Maintain optimum temperature for workers• Improve overall thermal comfort• Decrease sick building syndrome

DISADVANTAGES OF IEQ

• Cost of construction will be high• Maintenance cost is high• Hard to satisfy everyone’s desired temperature• Once the building is built, changing the existing

construction is very hard

INDOOR ENVIRONMENT QUALITY (IEQ) ENHANCEMENT SYSTEM

• Air ConditionerThe main function of an air conditioning system is mainly to produce cool ventilation inside the building in which the heat is taken out from a certain location to give a chilled air effect.

INDOOR ENVIRONMENT QUALITY (IEQ) ENHANCEMENT SYSTEM

• Daylight System

- A daylighting system consists of not only daylight apertures, such as skylights and windows but also comes with daylight responsive lighting control system.

- Working long term in electric lighting is believed to be deleterious to health, and working by daylight is believed to less stress and discomfort.

METHODOLOGY

A specific space is chosen from each of the building:Block C Level 5 (Taylor’s)Old Wing, level 4, Mariam Ward (Assunta)

Survey forms were distributed out to 30 male and female at each space

Aim: To study about the existence of Sick Building Syndrome.

EXAMPLES OF SURVEY QUESTIONS

Question 1

The symptom that you face:

headache, drowsiness,

dizziness and irritation, cause by the working environment?

NOYES

Question 5

Blocked vents due to dust,

files, and etc.?

NOYES

EXAMPLES OF SURVEY QUESTIONS

Question 13

Is outdoor air actually

getting into the building?

NOYES

OVERALL RESULTS
