Veterinary Laboratory at Tai Lung Farm
Veterinary Laboratory at Tai Lung Farm, Sheung Shui
Project ScopeThe 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
Project Scope
Veterinary Laboratory at Tai Lung Farm, Sheung Shui
SITE
Site Location
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 Site
Veterinary Laboratory at Tai Lung Farm, Sheung Shui
SITE
Existing ground was built with an abandoned single storey Mushroom Laboratory and covered by the dense vegetations of shrubs and trees.

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

Prevailing Wind
View to Tai Lung FarmView to Hong Kong Golf Club
• 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
ENVIRONMENTAL DESIGN
Preservation of Existing Site
• Building Shape is developed with respect to the topographical contours
• Soil Balance of the Cut & Fill to minimize the dumping

Preservation of Existing Trees & Landscape
Ecological Impact
The Design
ENVIRONMENTAL DESIGN
-Preserved trees are well-protected during the construction period.
-Building bulks are positioned to achieve minimal cutting of existing well-grown trees.
Harmony to Existing Environment
• Use of native species in compensatory landscaping design
• Maximize the provisions of roof garden and landscaped terrace
Ecological Impact
ENVIRONMENTAL DESIGN
The Design
Orientation• Linear block with least openings is deliberately shielding off all accommodation from the west-sided solar exposure.

ENVIRONMENTAL DESIGN
Natural Lighting
The Design
- 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
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.
ENVIRONMENTAL DESIGN
The Design
Air Conditioning System •DDC control system with plant optimization programme control to maximize operation efficiency
•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
BUILDING SERVICES DESIGN
The 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
The Design
BUILDING SERVICES DESIGN
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 Fans
• Concealed exhaust system for Safety Cabinets and Fume Cupboard equipped with HEPA filters
SUSTAINABLE DESIGN
The 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.

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.
