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.
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.
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
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.
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.
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
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.
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.
