United Christian College (Kowloon East) is developing a 5,000sq.m.<br />
extension programme including dormitory, canteen, chapel,<br />
gymnasium, activity rooms, basketball court <strong>and</strong> indoor swimming<br />
pool. Envisioned by the user, this school extension aspires to create “a<br />
different sky for learning” <strong>and</strong> serves to cultivate students to respect<br />
environmental sustainability, among other virtues.<br />
To this end, the building shall serve as a “living educational & r<strong>esearch</strong><br />
tool” in which environmental loadings are minimized both locally<br />
<strong>and</strong> globally throughout the life cycle. Pre-assessments on building<br />
environmental performance, based on CEPAS <strong>and</strong> LEED (for School<br />
2007), are performed <strong>and</strong> adopted as design guidelines. Qualitative <strong>and</strong><br />
quantitative studies using computer simulation technologies are carried<br />
out to achieve specific environmental performances. Several focus areas<br />
are summarized below:<br />
Natural Ventilation<br />
Cross ventilation, stack effect, wind catcher <strong>and</strong> wing wall are r<strong>esearch</strong>ed<br />
<strong>and</strong> then incorporated as applicable. With the help of dynamic thermal<br />
analysis using IES Virtual Environment & CFD, an addition of 1/3 to 2/3<br />
natural ventilation mode in various areas can be achieved.<br />
Daylighting<br />
Vertical Daylight Factor (VDF) is employed to study the daylight<br />
performance of a typical dormitory unit. An average lux level of 300-<br />
400 can be achieved with 21% VDF. Desktop Radiance is also used to<br />
simulate the actual lighting effect.<br />
An approximate 0.45 “Green Plot Ratio” can be achieved through<br />
design.<br />
Resource Conservation<br />
<strong>The</strong> principle of 4Rs (i.e. Reduce, Renew, Reuse <strong>and</strong> Recycle) is adopted<br />
with emphasis on using less materials.<br />
Waste Minimization<br />
Grey water from the swimming pool will be used for irrigation or floor<br />
cleansing while kitchen waste will be composted as fertilizer.<br />
Life Cycle Assessment (LCA)<br />
Computer LCA software is used. Over 80% of total energy consumption<br />
falls in the operation stage of the building while a 10% annual energy<br />
consumption reduction is noted with natural ventilation potential being<br />
maximized.<br />
