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

Site Location
Veterinary Laboratory at Tai Lung Farm, Sheung
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.

The Design
ENVIRONMENTAL DESIGN
View to Tai Lung Farm
View to Hong Kong Golf Club
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.

8
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
10
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
The Design
11
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
12
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

18
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.
