1. Project Introduction and Methodology

This is a research integration report of light and acoustic elements within the proposed

community building in studio 5. The building is a community library which serve its function to

provide a local gathering space for knowledge sharing, artwork creation and communication. The

total built up functional space for the library is 2000 meter square.

The research project is divided into two categories: Light and Acoustics Integration Design.

For light integration design, three spaces are selected for the study, as tabulated below.

light available outside. (%)

DF – ratio of internal light level to external light level

DF = 𝑬𝒊

3. Proposal Reflected Ceiling Plan

Taking N = 13

By formula, (SHR) spacing to mounting height ratio is 3:2

The mounting height = 1.5m

3: 2 = Spacing: 1.5m

1.5 X 1.5 = 2.25metres

The number of rows of lamps is calculated by dividing the width of the room (3.9m)

3.9 m / 2.25 m = 1.73 (2 rows)

Note: Half the spacing (1.125m) is used for the ends of rows

Hence, 1 row = N/2 = 4/2 = 2

Longitudinal spacing between lamps can be calculated by dividing the length of the building by the no of

lamps per row,

Length of the building:

5.4m / 2 = 2.7

Half the spacing at both ends = 2.7 / 2

= 1.35m

Building Code of Australia Requires

The Building Code of Australia (BCA) requires a wall separating sole occupancy units, or between a sole occupancy

unit and a public corridor, plant room, lift shaft, stairway, hallway or the like, to have a Weighted Sound Reduction

Index (Rw) not less than 45.

Where a habitable room such as a living room, dining room, family room, bedroom, study and the like, but not

including the kitchen, in one sole occupancy unit is situated next to a bathroom, sanitary compartment, kitchen or

laundry in an adjoining unit, the wall separating the units must have an Rw not less than 50. In addition, the dividing

wall construction must provide a “satisfactory” level of impact sound isolation.

Soil and waste pipes which serve or pass through more than one sole occupancy unit must be separated by a

construction which provides a minimum of Rw 45 if adjacent to a habitable room (other than a kitchen), or Rw 30 if

the adjacent room is a kitchen, bathroom, laundry or the like.

Note: Rating of sound insulation in buildings and of building elements now refer to a “Weighted Sound Reduction

Index (Rw )” to replace “ Sound Transmission Class (STC)”. This was changed in amendment No. 6 to BCA 96.

The International Building Code (ref. 4)

contains requirements to regulate sound transmission through interior partitions separating adjacent

dwelling units and separating dwelling units from adjacent public areas, such as hallways, corridors,

stairs or service areas. Partitions serving the above purposes must have a sound transmission class of at

least 50 dB for airborne noise when tested in accordance with ASTM E90. If field tested, an STC of 45

must be achieved. In addition, penetrations and openings in these partitions must be sealed, lined or

otherwise treated to maintain the STC. Guidance on achieving this for masonry walls is contained below

in Design and Construction. The International Residential Code (ref. 5) contains similar requirements,

but with a minimum STC rating of 45 dB when tested in accordance with ASTM E90 for walls and

floor/ceiling assemblies separating dwelling units.

Pacific Sound Absorption Panels

Pacific Sound Absorption Panels consist of particle board sheet, one face of which is factory-

machined with a proprietary slot pattern. The panel is categorized as a Helmholtz absorber.

A range of factory or site applied finishes are available for the panels, including timber veneer,

fabrics, paint or lacquer.

Decorative slot patterns are possible which can be customized to clients’ requirements for special

architectural or corporate image effects.

Standard Height (mm) Standard Width (mm) Panel weight (kg/m2) Panel Thickness (mm) NRC Rating

Notes:

1. Other larger panel sizes up to 3660 x 1820mm may be possible provided appropriate handling, transport and storage

are allowed for.

APPLICATIONS

Sound Absorption Panels are used to control acoustics in spaces such as theatres, concert

chambers, lecture theatres, music studios, gymnasia, conference rooms, boardrooms, executive

offices, school halls, churches, computer rooms and industrial noise isolation rooms.

Panels are used for wall or ceiling applications.

BENEFITS

Range of surface finishes including timber veneer.

High impact resistance.

Customised decorative slot patterns available.

High wall STC.

No imported materials.

Special surface coatings are available for improving Early Fire Hazard indices if required.

CONDITIONS OF USE

Pacific Sound Absorption Panels are intended for conditions of dry internal use where there is

adequate ventilation consistent with the recommended environments for Superflake Particle

Board (Fletcher Wood Panels Ltd).

Panels should be stored flat with at least 3 full-width packers per sheet underneath.

Site applied paint coatings should be to the outer surface of the panel only. Light overspray is

permitted inside surface grooving.

Fabric claddings must be discussed with Pacific Doors prior to final specification.

If panels are cleaned then aqueous cleaning solutions should be applied to the outer panel

surfaces only, or non-aqueous cleaning products could be used.

SEALS

The perimeter frame seals are self-adhesive seals mounted in the frame rebate, so are hidden when the door is

closed.

The bottom seal (Type L) is an automatic door seal that lifts clear of the floor when the door is opened. The seal is

fully mortised in a groove in the bottom edge of the door.

The bottom seal must close onto a smooth, flat and level surface in order to seal as intended.

HARDWARE

The AD300 requires suitable latching in order for the frame seals to fully seal the gap between door leaf and frame.

Practically any standard door hardware can be used on the AD300, however the proposed hardware must be advised

to Pacific Door Systems Ltd to assess the suitability, before manufacture.
