INTRODUCTION (MASTER LAYOUT PLAN- GROUP PROJECT)
LOCATION Mui Wo is a Transition HUB Between Islands and Lantau Island
A master layout plan that utilises the centrality, connectivity and the existing inter-island system of Mui Wo to other nearby islands; Lantau, Peng Chau and Cheung Chau to propose a sub regional art and cultural district, which is believed to foster local-global exchange.

INTRODUCTION- DESIGN DEVELOPMENT (WORKSHOP HUB- INDIVIDUAL PROJECT)
DESIGN INTENTION
ACTION
The workshop hub is aim for shares the traditional handicraft to the public and islanders. and also provide a place to the islanders
The project is to repurpose the unused school.
Create the void area to engage the islander's ups there for daily use. They meeting friends and learning the workshop through walking on the building. Like walking street on the island.
Keep the existing structure

SUPPORTING WORKSHOP EXHIBITION
WORKSHOP: 26 ROOMS
SUPPORTING: 19 ROOMS
The containers for the workshop and supporting area, that can move and replace through time. and can move to different islands for exhibition and use.

NATURAL DAYLIGHT STRATEGIES (BEFORE)
The typical school design is not considered the sun path and daylight strategies. A. The corridor and special classroom cannot have daylight. B. The winter daylight can fulfil the classroom, but cannot extend to the corridor.
11
NATURAL DAYLIGHT STRATEGIES (AFTER)
The design strategy is to break the floor and create a skylight on the existing building. That can makes the daylight fulfil the Workshop(classroom), corridor and supporting area(Special classroom).

VENTILATION STRATEGIES (BEFORE)
The Existing design cannot create ventilation convection, that will keep the heated air on the internal space and corridor.
15
VENTILATION STRATEGIES (AFTER)
The design strategy is to break the floor and create more void areas to create ventilation convection through the whole internal area. The heated air will leave through the roof opening.

STRUCTURAL STRATEGY- MODULAR SYSTEM STRUCTURE FRAME
The Existing building is a concrete structure.
MODULAR SYSTEM
STEP 1 The modular system is placed on the platform and ready to lift up to the planned location.
Create the I-beam and t ra c k to l o a d i n g a n d move the container to inside the frame.
STEP 2 Align the platform to the empty slot precisely.
STEP 3 The docking process begins, The modular system slides into the right position and connected to the building services.
STEP 4 Docking completed. Process to install next module.
STEP 5 The adaptable parts such as stair, railing can be placed in between different modules.

CALCULATIONS- U-VALUES (GROUND FLOOR)
The IP 3/90 formula is: U = 0.05 + 1.65(P/A) – 0.6(P/A) ²
Knowing the additional component thermal resistance that the insulation must provide we can then calculate the required thickness of insulation from the thermal conductivity of the material.
Where:
Floor Rt1 calculation:
U = U-Value of the uninsulated floor (W/m²K). P = Length of the exposed perimeter (m). A = Area of the floor (m²)
U = 1/ Rt1
Exposed floor perimeter: 144.6m
Existing Building area Floor Area: 835 sqm.
U x Rt1 = 1 P = 25+14+1+11+44+10.8+14.2+4.1m = 144.6m A = 835m2
P/A = 144.6m/835m2 P/A = 0.173m/m2 U = 0.05 + 1.65 x (P/A) – 0.6 x (P/A) ² U = 0.05 + 1.65 x (0.173) – 0.6 x (0.173) ² U = 0.05 + 1.65 x (0.173) – 0.6 x (0.173 x 0.173) U = 0.05 + 0.285 – 0.6 x (0.03)
Rt1 = 1/U Rt1 = 1/0.32 Rt1 = 3.125
Rt2 value calculation from Target U-Value: U = 1/ Rt2 U x Rt2 = 1 Rt2 = 1/U Rt2 = 1/0.25 (U-Value target) Rt2 = 4
G/F RECOMMENDED U-VALUES- ENGLAND NON DOMESTIC
U = 0.05 + 0.285 – 0.018 U = 0.317 U = 0.32 (round-up)
U-Values of un-insulated ground floor The formula yields the following values for different perimeter to area ratios.
Required additional thermal resistance to achieve U-Value target: Rt_Insulation = Rt2 - Rt1 Rt_Insulation = 4 - 3.125 Rt_Insulation = 0.875 k = Insulation thermal conductivity of KingSpan
The above formula shows that only floor plans with P/A ratios less than 0.1253 will meet the new building regulations without additional insulation. Using the figures above we can calculate the effective thermal resistance of the uninsulated floor (m²K/W) (this is the reciprocal of the U-Value).
Rt_Insulation = d/k
*In order to meet the new building regulations
Rt_Insulation x k = d
for a U-Value no greater than 0.25 we must therefore increase the thermal resistance to at least 4.0 by the addition of insulation.
d = Rt_Insulation x k d = 0.857 m²K/W x 0.022 W/Mk (K value from Thermafloor TF70) d = 0.018.8854m d = 0.019m Converted to mm d = 19 mm (insulation thickness required to achieve target)
