Veterinary Laboratory at Tai Lung Farm

1. Veterinary Laboratory at Tai Lung Farm

2. Veterinary Laboratory at Tai Lung Farm, Sheung Shui 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 Project Scope

3. 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 Site

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

5. Project Data Design Proposal Veterinary Laboratory at Tai Lung Farm, Sheung Shui Commencement date: 16/10/2000 Site area: 2,800 sq.m. Completion date: 31/12/2001 GFA: 1,107m2 Contract Sum: HK $39.33million Overall height: 11.40m No. of storeys: 3 storeys

7. The Design ENVIRONMENTAL DESIGN View to Hong Kong Golf Club View to Tai Lung Farm 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 Minimal Land-take Impact • Building footprint was spread with necessary area for • adequate provisions only • 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. 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. The Design ENVIRONMENTAL DESIGN Natural Ventilation • Openable windows allowed the natural ventilation to reduce the operation • period of A/C System during the mild season

14. The Design 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. The Design 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. The Design 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. The Design 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. The Design 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. The Design 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. The Design 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.
