2 EXPERT EVALUATION

2.1 Site Environs

2.1.1 The Subject Site, Kai Tak Cruise Terminal Building, is located in the south-eastern part of Kowloon Peninsula with a site area of about 7.6 hectares. It is presently an open area situated at the southern tip of the former Kai Tak Airport runway at the Kai Tak Development. The Subject Site is surrounded by the Victoria Harbour and the Kwun Tong Typhoon Shelter on three sides. To the north-east of the Subject Site, across the Kwun Tong Typhoon Shelter, is the Kwun Tong / Kowloon Bay area. The Subject Site is directly aligned with the Lei Yue Mun Channel which is the primary course for cruise ships entering the harbour.

2.1.2 The Subject Site is connected to Kowloon City / San Po Kong area through the proposed Kai Tak Development on the north-western side and will be connected to Kwun Tong / Kowloon Bay area by a bridge on the north-eastern side.

2.1.3 The Subject Site is bounded immediately by the proposed Tourism Node site and the proposed Runway Park site to the north-east and the proposed Heliport site to the south-east. Area on the south-western side of the Subject Site is restricted area of the CTB. Pedestrians are not allowed to enter to that zone. To the northwest of the Subject Site is the proposed Waterfront Promenade.

2.1.4 Figure 2.1 shows the location and the environs of the Subject Site.

Figure 2.1 Location of the Subject Site

2.2 Prevailing Wind Condition

2.2.1 The Subject Site is located in the south-eastern part of Kowloon Peninsula. As shown in the aerial photo (Figure 2.2 refers), the terrain adjacent to the Subject Site comprises sea and a large piece of flat land which will be developed into medium-rise commercial and residential uses. Influence of local topography to the wind flow pattern at the Subject Site should be minimal.

2.2.2 With regards to the local wind conditions of the Subject Site, lower level (at 16m above mean sea level) wind data are available from the Kai Tak (SE) Automatic Weather Station operated by the Hong Kong Observatory. The Kai Tak Automatic Weather Station is set on the roof of the former Kai Tak Airport Fire Station situated at the southern tip of the former Kai Tak Airport runway.

2.2.3 In accordance with the recent five years (2006 to 2010) annual wind roses from the Kai Tak Automatic Weather Station (Figure 2.3 refers), the annual prevailing winds for these years at the lower level of the area are predominantly easterly and south-easterly winds together with some south-westerly winds. The summer prevailing winds are mainly from the southeast and the southwest quadrants.

2.2.4 The Kai Tak Automatic Weather Station is very close to the Subject Site (200m to the north-east from the site boundary). Although the wind flow pattern at the Subject Site would be influenced by the existing and planned development, the wind flow pattern at the Subject Site can be represented by that recorded at the Kai Tak Automatic Weather Station.

2.3 Site Wind Availability

2.3.1 With reference to the “Experimental Site Wind Availability Study for the Proposed Kai Tak Development, Hong Kong – Investigation Report WWTF013-2009”, the Subject Site falls within Study Area A of the above study. A 1:2000 scale topography study was undertaken to determine the effects of the surrounding topography and urban environment on the wind availability data including mean wind direction, mean wind speed and turbulence intensity.

2.3.2 The topography study results were subsequently combined with a statistical model of the Kai Tak non-typhoon wind climate, based on measurements taken at the Kai Tak Automatic Weather Station to determine directional wind characteristics and availability for the study area.

2.3.3 The wind tunnel testing techniques used for the topography study satisfied the quality assurance requirements stipulated in the Australasian Wind Engineering Society Quality Assurance Manual, AWES-QAM-1-2001 (2001) and the American Society of Civil Engineers Manual and Report on Engineering Practice No.67 for Wind Tunnel Studies of Building and Structures (1999). It was also undertaken in accordance with the recommendations of Planning Department’s Feasibility Study for Establishment of Air Ventilation Assessment System – Final Report (2005) and Technical Guide for Air Ventilation Assessment for Developments in Hong Kong (2006).

2.3.4 The data from the experimental site wind availability study is therefore adopted for this AVA study for the Subject Site. The coverage of Study Area A and the relevant wind availability data are extracted from the topography study and shown in Appendix A. Photographs of the 1:2000 scale topographical model of the proposed Kai Tak Development for Study Area A under north, east, south and west directions are shown in Figure 2.4 to Figure 2.7.

2.3.5 Based on the findings from the experimental site wind availability study, the annual prevailing non-typhoon winds at the proposed Kai Tak Development area are mainly from the southeast quadrant. During summer months (June to August), the prevailing non-typhoon winds are mainly from the southeast and southwest quadrants.

2.3.6 The findings also point out that significant reductions in the magnitude of wind speed were measured at elevations below 150mPD for N, NNE, NE, ENE and E wind directions. Those were caused by the Lion Rock to the north and Fei Ngo Shan to the northeast of the proposed Kai Tak Development area. Residential and commercial buildings surrounding the proposed Kai Tak Development area also have some effect on the magnitude of wind speed. Besides, the mountains located on Hong Kong Island reduced wind speed from the south and south-westerly directions. Wind approaching from the southeast was the least affected due to the relatively open water of the Victoria Harbour and Lei Yue Mun Channel. These results are in line with the wind roses recorded at Kai Tak Automatic Weather Station.

2.3.7 The annual and summer wind roses at 150 mPD (level not affected by local topography) based on the results of the experimental site wind availability study are shown in Figure 2.8. The wind roses indicate the dominance of each of the 16 wind directions and distribution of the wind speed at 150 mPD. The percentage of annual and summer season occurrence of a particular wind direction at level 150 mPD is presented in Table 2.1.

2.3.8 As shown in Table 2.1, ESE wind is the most predominant wind at upper level and contributes 19.2% of in a year. Other predominant winds at upper level include E, SE and SSE winds.

3 ASSESSMENT METHODOLOGY

3.1 General

3.1.1 This AVA study was carried out in accordance with the guidelines stipulated in the Technical Guide for AVA for Developments in Hong Kong with regards to Computational Fluid Dynamics (CFD) modelling. Reference was also made to the “Recommendations on the use of CFD in Predicting Pedestrian Wind Environment” issued by a working group of the COST action C14 “Impact of Wind and Storms on City Life and Built Environment” (COST stands for the European Cooperation in the field of Scientific and Technical Research). COST action C14 is developed by European Laboratories/Institutes dealing with wind and/or structural engineering, whose cumulative skills, expertise and facilities have an internationally leading position. Thus, it is considered that the COST action C14 is a valid and good reference for CFD modelling in AVA study.

3.2 Modelling Tool and Model Setup

3.2.1 Assessment was conducted by means of 3-dimensional CFD model. The well-recognised commercial CFD package FLUENT was used in this exercise. FLUENT model had been widely applied for various AVA research and studies worldwide. The accuracy level of the FLUENT model was very much accepted by the industry for AVA application.

3.2.2 Wind Directions: In the CFD model, all 16 wind directions together with their respective % of occurrence determined for the Subject Site were adopted for simulation of air ventilation performance (Table 2.1 refers).

3.2.3 Vertical Wind Profile: Wind environment under different wind directions was defined in the CFD environment. The wind profiles for the 16 wind directions will follow those determined from the experimental site wind availability study as extracted in Appendix A.

3.2.4 Turbulence Model: As recommended in COST action C14, realizable K-epsilon turbulence model was adopted in the CFD model to simulate the real life problem. Common computational fluid dynamics equations were adopted in the analysis.

3.2.5 Variables including fluid velocities and fluid static pressure were calculated throughout the domain. The CFD code captures, simulates and determines the air flow inside the domain under study based on viscous fluid turbulence model. Solutions were obtained by iterations.

3.2.6 Computational Domain: A 3-dimensional CFD model was constructed to capture all major components such as topographical features and buildings within and in the vicinity of the Project Area that would likely affect the wind flow. The methodology described in the Technical Guide was adopted for this assessment. According to the Technical Guide, the Assessment Area and the Surrounding Area should include the project’s surrounding up to a perpendicular distance of 1H and 2H respectively from the project boundary, H being the height of the tallest building on site. The tallest structure of CTB is the radar tower which is about 52m tall. Therefore, a study area covering not less than 104m from the Subject Site boundary will be included in the formulation of CFD model and will be further extended to include the Kwun Tong Waterfront Area and South Apron Corner of the former Kai Tak Airport.

3.2.7 The inflow face of the computational domain is set as the velocity inlet condition and the outflow face is set as the zero gradient condition. For the two lateral and top faces, symmetric boundary condition is used. Lastly for the ground and building walls, no slip condition is employed.

3.2.8 The size of the domain of the CFD model for this Study is approximately 5092m (L) x 5092m (W) x 600m (H) and contains about 14,000,000 cells. Given the large computational domain adopted in this assessment and the physical limitation on the computational resources of the CFD model, the horizontal and vertical grid size employed in the CFD model in the vicinity of the Project Area was taken as a global minimum size of 2m and was increased for the grid

AECOM Asia Co. Ltd. 11 April 2012

Cruise Terminal Building and Ancillary Facilities For the Kai Tak Cruise Terminal Development Architectural Services Department Air Ventilation Assessment

cells further away from the Project Area at a growth ratio of 1.6. The global maximum size of cells is 64m. Smaller cell size up to 0.5m was used for the CTB in order to depict the special features of the CTB. Besides, four layers of prism cells (each layer of 0.5m thick) were employed above the terrain. In the CFD model, the pedestrian level test points were all located at 2m above ground level at the fourth cell away from the terrain to ensure a better resolution of flow close to the ground as per the recommendation of COST action C14.

3.2.9 The advection terms of the momentum and viscous terms are resolved with the second order numerical schemes. The scaled residuals are converged to an order of magnitude of at least 1 x 10-4 as recommended in COST action C14.

3.2.10 Figure 3.1 shows the boundaries of the Project Area, Assessment Area and Surrounding Area that were examined in this AVA. Figure 3.2 and Figure 3.3 show respectively the extent of the computational domain that was adopted in the CFD model and an example cross-sectional wind velocity ratio vector plot across the computational domain under one wind direction. Images of the general model setup and grid cell setup in the CFD model are shown in Figure 3.4 and Figure 3.5 respectively.

3.2.11 Test Points: Perimeter test points and overall test points were selected within the Assessment Area in order to assess the impact on the immediate surroundings and local areas respectively. Perimeter test points were selected along the boundary of the Project Area with separation distance of about 50m. According to the Technical Guide, perimeter test points are normally not necessary at perimeter where there is no major air ventilation issues e.g. waterfront area with ample sea breeze and inaccessible land such as the cruise terminal restricted area in this case. Therefore, perimeter points were not selected along the harbour front boundary to the southwest of the cruise terminal building. Overall test points were evenly distributed over surrounding open spaces, streets, landscape deck, podium and other parts of the Assessment Area where pedestrian can or will mostly access. All test points are elevated at 2m above ground or podium level.

3.2.12 The selected overall test points were grouped based on the land use / sensitive receivers as shown in Figure 3.6 and summarized in Table 3.1 for ease of discussion. There are 20 perimeter test points (with prefix “P”) and 50 overall test points (with prefix “T”) selected for the purpose of this AVA study. No overall test points were selected in area where pedestrians are difficult to access such as cruise terminal restricted area and the heliport area.

3.3 Wind Velocity Ratio

3.3.1 Wind velocity ratio (VR) indicates how much of the wind availability is experienced by pedestrians on the ground which is a relatively simple indicator to reflect the wind environment of the study site. VR is defined as VR = VP /VINF where VINF is the wind velocity at the top of the wind boundary layer and it would not be affected by the ground roughness and local site features and VP is the wind velocity at the 2m pedestrian level.

3.3.2 VRW is the frequency weighted wind velocity ratio calculated based on the frequency of occurrence of all the 16 wind directions for the purpose of comparison.

3.3.3 For Site Air Ventilation Assessment, the Site Spatial Average Wind Velocity Ratio (SVRW) and individual VRW of all perimeter test points are reported. SVRW is the average of VRW of all perimeter test points.

3.3.4 For Local Air Ventilation Assessment, the Local Spatial Average Wind Velocity Ratio (LVRW) of all overall test points and perimeter test points, and individual VRW of the overall test points are reported. LVRW is the average of all overall test points and perimeter test points.

3.3.5 The SVRW and LVRW are worked out so as to understand the overall impact of air ventilation on the immediate and further surroundings of the Project Area due to the proposed development.

3.4 Development Schemes Assessed in this Study

3.4.1 This AVA Study assessed and compared the air ventilation performance of two development schemes design options namely

y Basic Scheme – a scheme that contains important features of the CTB which were designed in the early stage, it is based on the current General Building Plan and the total gross floor area (GFA) is within the allowable GFA and the building height of main roof comply with the height limit requirement as stated in the draft Kai Tak OZP No. S/K22/3. y Current Scheme – a scheme that has incorporated further air ventilation mitigation and improvement measures into the Basic Scheme.

3.4.2 The Subject Site will be developed into the Kai Tak Cruise Terminal Building. The development includes two alongside berths, support facilities such as customs, immigration, quarantine counters, baggage handling etc., and a commercial area with offices and retail facilities. It has a rectangular, elongated plan and comprises four floors as follows:

y Ground Floor – primarily facilitates vehicle access to the terminal. y First Floor – a partially enclosed level containing the boarding gates. y Second Floor – contains retail space and a large open viewing deck y Roof Deck – a landscaped recreational area

3.4.3 During the design of the Basic Scheme, the design team had incorporated the following design merits from air ventilation perspective:

y Natural air ventilation is allowed vertically through the atriums; y Natural air ventilation is allowed horizontally below the glass canopy and above the atriums; y Natural air ventilation is allowed through the trellis at the two middle canopies facing the sea; y The public colonnade is naturally ventilated; y G/F and 1/F pickup/drop off area is naturally ventilated. 3.4.4 The Current Scheme further incorporated a number of air ventilation mitigation and improvement measures. The differences between two development schemes are summarized as follow:

y The height of barriers on the park side at Ground Floor were reduced from 8.5m to 2.5m; y The vehicular exit in the ancillary building was shifted about 70m to the south; y The enclosed structures up to the roof level at the two ends of the Second Floor were transformed into a large open viewing deck; y The height of the ancillary building was reduced partially from 2-storey high to 1-storey high; y The extent of canopies, facing the park, was reduced

3.4.5 The 3D models of the Basic Scheme and the Current Scheme are shown in Figure 3.7 to Figure 3.9 while improvement measures incorporated into the Current scheme are highlighted in Figure 3.10 and Figure 3.11.

4 KEY FINDINGS OF AVA STUDY

4.1 Local Situation

4.1.1 The local situation including the site environs, site wind environment, and site wind availability of the Subject Site are described in Section 2 above.

4.2 Air Ventilation Issues

4.2.1 As discussed in Section 2 above, the Subject Site is located at the southern tip of the former Kai Tak Airport runway. It has a rectangular, elongated plan and comprises four floors with maximum height of 52m (height of the radar tower). The height of the main building of CTB is only about 30m tall. It is a relatively short building comparing with other surrounding hotels / commercial buildings.

4.2.2 In accordance with the wind availability data, the Kai Tak area relies heavily on easterly and south-easterly winds for ventilation during most time in a year. Therefore, any blockage to these prevailing winds should be avoided as far as possible.

4.2.3 Although the site foot print of the CTB is large, the long side of the CTB aligns with the southeast prevailing wind. This enhances the air ventilation performance to the commercial area at the northwest and reduces blockage to wind flow to a minimal level.

4.2.4 For wind blowing from the southwest quadrant, the impacts of wind blockage is not significant because of the short height and streamlined structural profile of CTB and that the south-westerly wind will only occur for a small percentage of time in a year.

4.3 Wind Velocity Ratio Results

4.3.1 A summary of the predicted wind velocity ratios for the Perimeter Test Points and the Overall Test Points as well as the SVRW and LVRW are presented in Table 4.1 below. Details of the predicted wind velocity ratios are presented in Appendix B.

4.4 Site Ventilation Assessment

4.4.1 The SVRW indicates how the lower portion of the buildings on the project site may affect the wind environment of its immediate vicinity. The predicted SVRW for the Basic Scheme and the Current Scheme are 0.217 and 0.224 respectively.

4.4.2 For the wind directions with highest probability of annual occurrence (ESE, E and SE direction), improvement in SVRW can be observed. A significant improvement of 15% and 11% can be observed for the ESE and SE wind direction respectively. This great improvement is mainly due to the transformation of enclosed structures to opening areas which would minimise the blockage to the wind flow and thus improve the wind environment (see Figure 4.3).

4.4.3 An increase of 3% in the VR can be observed for the E wind direction, this improvement is due to the reduction of height of barriers on the park side at Ground Floor (see Figure 4.4).

4.4.4 With the improvements achieved under these 3 prevailing wind directions, as shown in Figure 4.2 with the frequency weighted VR contour plots, relatively higher frequency weighted VR is observed around the CTB, in particular around the southeastern portion of the CTB, under the Current Scheme. This also demonstrates that the measures incorporated under the Current Scheme have improved the wind environment surrounding the CTB at pedestrian level.

4.5.1 The averaged LVRW for the Basic Scheme and the Current Scheme are 0.261 and 0.285 respectively, in other words, the predicted LVRW of the Current Scheme is better than the Basic Scheme which means the mitigation measures incorporated would merit the wind environment.

4.5.2 For the wind directions with highest probability of annual occurrence (ESE, E and SE direction), improvement in LVRW can be observed. A significant improvement of 12%, 10% and 20% can be observed for the ESE, E, and SE wind direction respectively.

4.5.3 As discussed above, the Subject Site is surrounded by sea on three sides and the long side of CTB align with the SE prevailing wind. Therefore, prevailing wind to the Subject Site would not be blocked significantly. As shown in Table 4.1 and Figure 4.1(c), under both the Basic Scheme and the Current Scheme, the averaged VRW for three out of four test point groups are above 0.3. This indicates that both the Basic Scheme and the Current Scheme are effective in allowing air ventilation of the surrounding areas.

4.5.4 Moreover, as shown in Table 4.1, the averaged VRW for all test point groups under the Current Scheme are better than those under the Basic Scheme. The average VRw of all overall test points for the Basic Scheme and the Current Scheme, as shown in Table 4.1, are 0.279 and 0.310 respectively. A higher VRw of overall test points indicates that the mitigation measures incorporated in the Current Scheme are effective in improving the ventilation performance at the surrounding areas.

4.5.5 Group 4 test points located on the roof level of the CTB. It will be developed into a landscaped recreational area in the future. Good air ventilation performance is important in this area. About 15% increase of average VRw can be found in Group 4 test points (roof level of the CTB). The reduction of the extent of canopies is shown to be effective in improving the air ventilation in the roof level.

5 SUMMARY AND CONCLUSIONS

5.1.1 This AVA Study Report aims at assessing the characteristics of the wind availability of the site, providing a general pattern and a quantitative estimate of wind performance at the pedestrian level under different wind directions and investigating the effectiveness of ventilation improvement measures of the Current Scheme.

5.1.2 To conclude, the proposed Subject Site has incorporated a number of ventilation improvement measures during the scheme design and the modelling results show that it maintains a good wind performance at the pedestrian level of the area around the Subject Site. No ventilation problem is found for the Subject Site. With the value greater than 0.2, the SVRW and LVRW of the Subject Site are found to be relatively higher than other territories of Hong Kong and the air ventilation preferment is satisfactory. The higher VRW of overall test points also proves that the mitigation measures incorporated in the Current Scheme are effective.
