Indoor environmental quality (IEQ) refers to the quality of a building's environment in relation to the health and well-being of those who occupy space within it. IEQ is affected by factors like air quality, temperature, lighting, acoustics, and HVAC systems. The document discusses surveys conducted at various office and healthcare facilities to understand how physical factors of the indoor workspace affect occupants. Issues identified include weak ventilation, noise levels, and lighting concerns. Recommended solutions involve improving ventilation, adding acoustic treatments, using low-VOC paints, and zoning work areas. Maintaining good IEQ can enhance occupant health, comfort, and productivity.

- 1. INDOOR ENVIRONMENTAL QUALITY IN OFFICE & HEALTHCARE Wilson Liew Yong Sheng Kevin Lee Kim Thiam Muhammad Hasif bin Alias Enoch Wong Geng Seng Kevin Lee Hee Xian Deepesh Ferag
- 2. What is INDOOR ENVIRONMENTAL QUALITY ( IEQ ) ?
- 4. HVAC
- 5. Heating, Ventilating, and Air Conditioning (HVAC) + Main functions of a building comfort system + Provide thermal comfort and acceptable indoor air quality + Improved (IEQ) + High performance HVAC system can result in considerable energy and cost saving
- 6. 1) Heating + heating the air within a space or by heating the occupants directly by radiation (wall, floor) + Normally for 4 season country . + sources: Hydronic - Electricity
- 7. 2) Ventilating + Process of "changing" or replacing air in any space + Ventilating maintains an adequate mixture of gases + Control temperature + Remove air contains to provide “Clean” air
- 8. 3) Air Conditioning + Refers to the sensible and latent cooling of air, i) Sensible cooling -- control of temperature. ii) Latent cooling -- control of air humidity. + Transferring heat between spaces + Provides cooling and humidity control
- 9. • Compressor- pump the gas up to a high temperature and pressure. • Condensing coil- where it loses energy (heat) and condenses into liquid phase. • Capillary tube- refrigerant liquid to flow at the proper rate. • evaporating coil- As the liquid refrigerant evaporates it absorbs energy (heat) from the inside air.
- 10. ACOUSTI C
- 11. What is acoustics? Acoustics is the study of all mechanical waves in gases, liquids and solids including topics such as: Vibrations Sound Ultrasound Infrasound The acoustics of steel, concrete and timber framed building absorbs sound differently because of the materials used in the exterior. Structure-wise, the thickness of each floor would contribute to how sound could transfer to upper or lower floor.
- 13. How it help IEQ? Greatly influence the design of the interior architecture. Absorb sound and reduce echoes (minimizing reflection)
- 14. LIGHTING
- 15. BASIC LIGHTING - Ambient lighting also known as general lighting gives a comfortable level of brightness without glare. - Task lighting helps you perform specific task in an area. - Accent lighting works as a part of an interior design scheme.
- 16. BASIC BULB Compact fluorescent lamps(CFL) Light-emitting diodes(LED) + provides visual comfort and efficiency. + energy saving and long lifetime. + designed to fit in a wide range of ceiling type.
- 17. In a workplace, workers tend to complain about the lighting. Too dim Too bright
- 18. Importance of IEQ ?
- 19. A GUIDELINE TO CONTROL Environmental Tobacco Smoke (ETS) Temperature Humidity Index (THI) Concentration Indoor Air Pollutants (VOC,PM) Indoor Noise Levels Daylight Glare Control
- 20. Prevention of 1) Sick Building Syndrome ( SBS ) 2) Building Related Illness ( BRI ) 3) Wastage of Resources SBS BRI Associated with acute discomfort. Simply sick. Causes are not known. Clinically defined illness and causes. Temporary, relief after leave building. Prolonged recovery times after leave bulding.
- 21. ACHIEVING COMFORT & HEALTHY ENVIRONMENT HELPS + Enhance the lives of building occupants. + Increase the resale value of the building. + Reduce liability for building owners.
- 22. What is OUR PROJECT ?
- 23. OFFICE CLINIC Taylor’s Admin. Centre Taylor’s Block C5 Office Sunway Hospital Taylor's HealthCare
- 24. Surveying Understand the relationship interior design and those who works within it Understand how physical factor of IEQ affects the worker
- 25. *reminder This entire survey is not exactly accurate and is entirely subjective due to the lack of equipment and devices for the research. Using the senses and opinions of the occupants which are entirely subjective to their opinions.
- 26. What is the METHODOLOGY ?
- 27. QUANTITATIVE METHOD To understand in what way the does the workspace affect the workers. QUALITATIVE METHODS To understand using levels (in words instead of numbers) to understand how the worker feel about the workspace.
- 28. Survey Form Divided into three sections 1. Demography of worker. 2. Understanding the worker. 3. Understanding workspace.
- 29. Aim : To understand the relationship between the interior design in both form and services and the occupants who works within it. Independent Variable : Gender and the condition of workspace. Dependent Variable : Preference and feelings towards the workspace Extraneous Variable : Amount of volunteer Materials : 50 Set of 5 paged survey forms & writing stationery. Volunteers : Taylor's Clinic and Health Service Centre 9 Sunway Hospital 10 Taylor's Administration Office 11 Taylor's Block C5 Office 15 Total = 45
- 30. What is the RESULT OR FINDING ?
- 31. Clinic • Ventilation is rather weak. • However, the exchange rate of air is functioning. • One of the problem the clinic faced is the noisiness of the setting. • The workspace also have sufficient natural light overall.
- 32. Hospital • Space is pressurized ventilated • Hospital is well ventilated. • • The overall temperature and smell are well-controlled including the brightness for work. • suffering from annoyance of chit chats and laughter.
- 33. Admin Office • Have a well ventilated area • The sufficient light the worker have.
- 34. C5 Office • Not ventilated as well as the Administration office. • • However, the odour and stench are still removed. • The acoustics of the office isn’t well managed but not severe. • The lighting of the room is bright enough to work and are glad that it’s not brighter than afternoon daylight.
- 35. What is the SOLUTION ?
- 36. OFFICE 1. Using Natural Ventilation 2. Increase Air Ventilation Rate 3. Avoid Use of Air Fresheners 4. Zoning of work areas.
- 37. HEALTHCARE 1. Add more Acoustics (Colourful) 2. Use of Nippon Anti-Bacterial paint + It prevents fungi and bacteria from breeding + Emits no odour during and after painting + Ultra Low VOC property + Reducing the risk of discomfort such as headaches and irratation.
