Project Scope

• The Project involves the demolition of a vacant
  single storey structure and a construction of a
  two-storey laboratory within the Tai Lung
  Experimental Farm to provide the following
  accommodations
• 10 (nos.) laboratories for conducting a wide
  range of veterinary experiments
• office accommodations
• supporting facilities for staff and technicians

Shui
SITE
The hilltop located at the southern corner
entrance of the Tai Lung Farm, Shueng Shui was
identified as the proposed site for the
construction of the New Veterinary Laboratory. It
is so close to well serve for the sampling of
imported poultries at the northern borders
adjoining the Mainland.

Tai Lung Farm
Prevailing Wind
Topographical Resources

• Building Forms are laid in accordance to the
  site profile and orientation
• to allow access of solar exposure in terms of
  the sunpath and prevailing
• wind.

• Layering of building blocks allows unobstructed
  views opened to the
• greenery of the Tai Lung Farm and Hong Kong
  Golf Club.

ENVIRONMENTAL DESIGN

• Building footprint was spread with necessary
  area for
• adequate provisions only

Minimal Land-take Impact

• Profile of original terrain was best maintained
  with minimal disturbance

The Design
9
ENVIRONMENTAL DESIGN

• Building Shape is developed with respect to the
  topographical contours

Preservation of Existing Site

• Soil Balance of the Cut Fill to minimize the
  dumping

The Design

Ecological Impact
ENVIRONMENTAL DESIGN

• Preserved trees are well-protected during the
  construction period.
• Building bulks are positioned to achieve minimal
  cutting of existing well-grown trees.

Preservation of Existing Trees Landscape

Ecological Impact
ENVIRONMENTAL DESIGN
Harmony to Existing Environment

• Use of native species in
• compensatory landscaping design

• Maximize the provisions of roof
• garden and landscaped terrace

The Design

ENVIRONMENTAL DESIGN
Linear Block
Orientation

• Linear block with least openings is deliberately
  shielding off all accommodation
• from the west-sided solar exposure.

13
ENVIRONMENTAL DESIGN
Natural Ventilation

• Openable windows allowed the natural ventilation
  to reduce the operation
• period of A/C System during the mild season

14
ENVIRONMENTAL DESIGN
Natural Lighting
- Balcony approach allows natural lighting for
major circulations to minimize the general
lightings
- Linear shape with depth of maximum 9m for all
accommodation to enhance daylight penetration
15
ENVIRONMENTAL DESIGN
Building Envelope Design

• Application of Low-E laminated glass and
  incorporation of Sunshades
• Canopy for glazing to minimize the solar
  exposure

• OTTV Calculation (with selected insulation and
  low-E glazing) 20.90 W/sq.m.

16
BUILDING SERVICES DESIGN

• DDC control system with plant optimization
• programme control to maximize operation
  efficiency

Air Conditioning System

• VAV design in air handling system to cope
• with fluctuating thermal load.

• Pre-fabricated CFCfree equipment to be used

• R134a refrigerant with ODP and GWP

17
BUILDING SERVICES DESIGN
Lighting System

• Separate control of lighting
• circuit between perimeter
• and interior zones

• Energy saving fluorescent tubes
• with electronic ballast and
• compact tubes to be used

• Capacitor bank installed to
• improve electrical system power
• over 0.85

SUSTAINABLE DESIGN
Concealed Exhaust Fans
Compatibility with Surrounding

• External wall finishes in rustic texture to
  match with natural surrounding

• Major building height in single storey to
  minimize visual impact to environment

• Concealed exhaust system for Safety Cabinets and
  Fume Cupboard equipped
• with HEPA filters

19
SUSTAINABLE DESIGN
Minimization of Material Resources

• Fairface concrete was constructed as the major
  portion of external walls and
• internal ceiling as the architectural features
  to minimize the finishes application.

• Concrete carriageway was stained with
  Lithochrome Chemstain
• as final finishes to waive the floor finishing
  works.

20
SUSTAINABLE DESIGN
Environmental Friendly Materials

• Foamglas made of recycled glass to be one of the
  lowest embodied energy
• insulation material for roofing was installed.

• Linoleum is a chemical-free and biodegradable
  flooring made from natural
• materials were widely applied as the laboratory
  floor finishes.
