Architecture and Sustainability

The University of Hong Kong (HKU) Comprehensive Information Database · 05 Campus Module (Supplementary Chapter)

The architectural language of HKU's campus spans an entire century, from the Edwardian Baroque red brick of 1912 to the Modular Integrated Construction (MiC) student residence in Wong Chuk Hang of 2023. At the same time, as a university embedded in a hillside on some of the world's most expensive land, HKU has, over the last two decades, tightly bound its expansion to sustainability. The Centennial Campus (2012) was HKU's first cluster of green buildings to secure Platinum certification under LEED and BEAM, and the Pokfield Campus, currently under construction and set to open in phases from 2027, represents the latest chapter in this trajectory. This article traces four narrative threads: the evolution of architectural styles, the green campus and carbon targets, the history of the Centennial Campus expansion, and Pokfield Campus: the next phase of westward expansion.

# 1. Three Eras of Architectural Style

# 1.1 Edwardian Red Brick (1910s–1930s): Colonial Classicism

HKU's oldest group of buildings belongs to the colonial classical language of the Edwardian era.

• Main Building (1912): According to Wikipedia, the Main Building is "Edwardian Baroque / Post-Renaissance style, using red brick with granite"^※. According to the Antiquities and Monuments Office (AMO), it is a "three-storey red-brick building supported by granite columns of the Ionic order, arranged symmetrically around a central clock tower"^※ (sources: Main Building · Wikipedia, AMO · Main Building). Its architect was Alfred Bryer of Leigh & Orange^※ (source: Main Building · Wikipedia).
• Eliot Hall / May Hall (1914/1915): According to the AMO, the two halls are "three-storey red-brick buildings reflecting 'the Edwardian fascination with classicism'"^※ (source: AMO · HKU Heritage).
• Hung Hing Ying Building (1919): According to the AMO, it is an example of "Neo-Classical style, characterised by red brick, timber trusses, and a central dome"^※ (source: AMO · HKU Heritage).

This group of red-brick buildings shares a common vocabulary of red brick + granite + classical orders + symmetrical layout, forming the core of HKU's "examples of British colonial architecture." According to the HKU Estates Office, they are also among the few surviving British colonial-style buildings in Hong Kong^※ (source: HKU Estates · Our Campuses). Architectural historical research notes that the Main Building extensively uses fair-faced red brick, echoing the tradition of "red-brick universities" in Britain. As a relatively modest building material compared to dressed stone, red brick in a sense also implied the "affordable and open to the public" positioning of these institutions, rather than being purely aristocratic stone structures. For the naming and details of individual buildings, see Iconic Buildings and Landmarks.

# 1.2 An Interlude of Chinese Motifs and Shanghai Plaster (1930s): Tang Chi Ngong Building

The Tang Chi Ngong Building (1931) from the 1930s presents a different language: According to the AMO, it is a "three-storey flat-roofed building finished with Shanghai plaster on its exterior walls, blending classical and Art Deco influences"^※ (source: AMO · HKU Heritage). Built as the dedicated premises for the School of Chinese, it stands in material and temperamental contrast to the Main Building's red brick, representing an "East-meets-West" interlude in HKU's architectural language.

# 1.3 Post-War Concrete and Contemporary Landmarks (1970s–2010s)

After the war, HKU's teaching and research buildings entered the concrete era, a prime example being the Knowles Building (1973). According to HKU Giving, the building has "each floor with a unique plan, using a grid of white brise-soleil sun-shading fins to balance the structural mass, and two levels of basements free of frames and walls to create a 'floating' visual effect"^※ (source: HKU Giving · Knowles Building). This emphasis on expressing the structure and using sun-shading fins aligns with the Modernist/Brutalist lineage popular in the post-war period. During the same era, the Robert Black College (1966), designed by architect Szeto Wai, took a different path—using modern construction techniques to blend a simple residential style inspired by traditional Chinese courtyard houses. For more details, see the Campus Building and Place Directory.

# 1.4 How to 'Walk Through' the Red Bricks: Heritage Trail and Guided Tours

HKU has transformed the history of these red-brick buildings into several public-facing visiting methods. According to the AMO and HKU, the University "has launched the 'HKU Heritage Sights and Sites' audio guide tour, allowing visitors to scan QR codes or listen online to learn about campus history at their own pace"^※. HKU also runs heritage trail guided tours led by "Scholastic Tour Leaders," offering the public (especially younger generations) a deeper understanding of HKU and Hong Kong's architectural and cultural history. According to HKU, the standard one-hour campus tour is led by "Green Gown Guides," with an itinerary covering the Fung Ping Shan Building, Hung Hing Ying Building, Main Building, the bronze statue of Sun Yat-sen by the lotus pond, and Eliot Hall^※. This route neatly strings together several declared monuments discussed in this article and in Iconic Buildings and Landmarks into a single physical trail.

Entering the contemporary era, HKU's most technically groundbreaking project is the student residence at 4 Police School Road, Wong Chuk Hang (2023), on the southern side of Hong Kong Island. According to the HKU Estates Office, this residence was "constructed using Modular Integrated Construction (MiC), making it one of the pioneering projects in Hong Kong to adopt this method"^※. Comprising two 17-storey modular towers and a three-storey non-residential podium, it provides approximately 1,200 student beds^※ at a cost of roughly HK$1.2 billion. Construction began in 2019 and was completed in September 2023. The 952 modular units used come in only five module sizes, prefabricated and pre-finished in a factory in mainland China before being transported to Wong Chuk Hang for on-site lifting and installation^※, significantly compressing the construction schedule and cost. The residence is also equipped with a mobile app for remotely controlling door locks, air conditioning, and lighting, as well as booking communal facilities and monitoring energy usage. This follows in the footsteps of the Centennial Campus's "interactive energy consumption displays" and is the latest example of HKU integrating "smart" features into its hall designs. The project has already received a Provisional Platinum rating from the Hong Kong Green Building Council's BEAM Plus scheme^※ and has won several awards, including the "MiC Project of the Year" (2022) and multiple Gold Seal awards for promoting MiC application, safety, and environmentally friendly construction (2023).

If the red bricks of the Main Building represent the starting point of HKU's architectural history, the prefabricated towers of the Wong Chuk Hang student residence are its latest punctuation mark. Separated by over a century, they provide the most intuitive point of comparison for 'reading' the generational changes in HKU's architecture: from artisan-laid red-brick monuments to factory-prefabricated, on-site assembled modular high-rises.

# 2. Green Campus and Carbon Targets

# 2.1 Carbon Neutrality Commitment

According to the HKU Sustainability Office, the University is committed to supporting the Hong Kong government's climate targets—achieving carbon neutrality by 2050, with an interim goal of a 50% reduction by 2035 relative to 2005 levels^※ (source: HKU Sustainability · Green Buildings). This target puts campus buildings, energy consumption, and renovations within a decarbonisation framework. According to the latest campus overview from the HKU Estates Office, as of June 2024, HKU's total land holding was approximately 54.8 hectares (Main Campus 17.7 ha, Kadoorie Centre 9.6 ha, Medical Campus 4.2 ha, other Pokfulam sites 23.3 ha), with a total gross floor area of around 729,000 m²^※ (source: HKU Annual Report 2024). This scale of continuous expansion has made "new build means green build" the default standard for HKU's estate projects over the past two decades.

# 2.2 Centennial Campus: A LEED / BEAM Platinum Green Cluster

The flagship of HKU's green buildings is the Centennial Campus. According to the HKU Estates Office, the Centennial Campus has "achieved Platinum certification under both the LEED and BEAM New Buildings rating schemes"^※ (source: HKU Estates · Centennial Campus); an HKU press release also confirms the Centennial Campus was awarded LEED Platinum, marking it as a high-performance green building^※ (source: HKU Press · Centennial Campus LEED Platinum).

According to the HKU Sustainability Office, the green design elements of the Centennial Campus include:

• Rooftop solar panels and building-integrated photovoltaic (BIPV) shading fins on the south-facing façade of the Jockey Club Tower^※ (source: HKU Sustainability · Green Buildings);
• Optimisation of natural daylight, ventilation, and rainwater runoff harvesting, along with the installation of renewable energy installations and high-efficiency building systems^※ (source: HKU Sustainability · Green Buildings);
• An interactive display showing real-time data on the Centennial Campus's energy, water, waste, and recycling^※ (source: HKU Sustainability · Green Buildings).

For the complete engineering narrative of the Centennial Campus, including the slope-cutting and cavern storage solutions, see the dedicated article on the Centennial Campus.

# 2.3 Existing Building Retrofits

Carbon targets are met not only through new green builds but also by retrofitting older buildings. According to the HKU Sustainability Office, the University is actively replacing thousands of fluorescent light tubes in old buildings with energy-efficient, mercury-free LED lamps, and installing new window films that provide thermal insulation and reduce UV and glare^※ (source: HKU Sustainability · Green Buildings). In an urban campus constrained by limited land and existing structures, "retrofitting the existing stock" is a crucial wing of HKU's decarbonisation strategy.

# 3. A History of Expansion: Incrementally Adding to an Urban Hillside

# 3.1 Successive Additions to the Main Campus

The HKU Main Campus was not built all at once but expanded building by building, in successive stages. The Main Building itself underwent additions: according to an HKU Estates Office photo caption, the Main Building "was extended in 1952 and 1958"^※ (source: HKU Estates · Main Building). Subsequently, post-war concrete teaching and research blocks were added incrementally up the hillside (e.g., the Knowles Building in 1973, Haking Wong Building in 1983, Run Run Shaw Building in 1985, Chong Yuet Ming Building in 1994; see the Campus Building and Place Directory for details). This method of "incremental additions along the hillside" gives the HKU campus a clearly visible stratigraphy of eras.

# 3.2 Centennial Campus: Westward Expansion by Cutting a Slope (2009–2012)

HKU's largest expansion before 2012 was carving out the Centennial Campus on a slope to the west of the Main Campus. According to the HKU Estates Office, the project was "to accommodate a larger student intake under the 3-3-4 education reform," with planning starting in 2005 and its opening in September 2012^※ (source: HKU Estates · Centennial Campus); according to Wikipedia, construction began in late 2009 and was completed in 2012^※ (source: University of Hong Kong · Wikipedia).

The Centennial Campus was built on a steep western slope of the Main Campus, requiring land to be carved out of the hillside and then stitched together at different elevations using elevated platforms and footbridges. This approach perfectly follows from HKU's overall campus form of being "distributed on an urban hillside and knitted together by vertical circulation" (see Campus Geography for geography and Transport and Facilities for vertical transit). According to the HKU Estates Office, the main consultant for the project was Wong & Ouyang (HK) Ltd., and the main contractor was Gammon Construction^※ (source: HKU Estates · Centennial Campus). For the complete narrative behind the project—including the reservoir cavern relocation works, the three academic buildings, and the "University Street"—see the dedicated article on the Centennial Campus.

# 4. Pokfield Campus: The Next Phase of Westward Expansion (Phased Opening from 2027)

If the Centennial Campus was HKU's largest expansion before 2012, then the Pokfield Campus, currently under construction and set to open in phases from 2027, is the latest and largest chapter in this trajectory of growth.

# 4.1 Site and Scale: The Former Flora Ho / Lindsay Ride Sports Centre Site

According to the HKU Estates Office, the Pokfield Campus project is located on a site covering the area around 111–113 Bonham Road and 13–21 Pokfulam Road^※, replacing the decades-old Flora Ho Sports Centre, Lindsay Ride Sports Centre, Stanley Smith Swimming Pool, and Pokfulam Road Staff Quarters (see the Campus Building and Place Directory and Transport and Facilities for more details on the original site). According to the Pokfield Campus website, the entire project spans approximately 130,000 m²^※ in gross floor area, a scale far exceeding that of the Centennial Campus.

# 4.2 Three Phases and Cost

According to the project profile from the HKU Estates Office, the Pokfield Campus is being delivered in three phases:

According to the HKU Estates Office, the estimated total project investment is roughly HK$8 billion^※. P&T Architects & Engineers Ltd. is the lead consultant, with a joint venture of Lanon and Able acting as contractor for Phases 1 & 2, and Build King Construction for Phase 3.

# 4.3 Positioning: A New Home for the Business School and a Hub for Sports, Residences, and Conferences

According to the Pokfield Campus website, the project's vision is to create "a contemporary hub that blends academic excellence, innovation, and sustainability," built upon the three pillars of Education, Innovation, and Outreach. It will become the new home of the HKU Business School. This marks another case, following the Faculty of Law's move into the Cheng Yu Tung Tower on the Centennial Campus in 2012, of an entire faculty receiving a dedicated, integrated campus (see the Campus Building and Place Directory and Centennial Campus). The project is within walking distance of the Centennial Campus, meaning that the Pokfield Campus is, to some degree, a geographical and functional extension of it.

According to the HKU Estates Office, the project will rebuild sports facilities and staff housing that have "served for decades." The new sports complex will feature an indoor heated swimming pool with an adjustable depth floor and various multi-purpose activity rooms (see Transport and Facilities for an account of the Flora Ho Sports Centre's closure in 2023).

# 4.4 Sustainability and Awards: A Green Building Upgrade from 'Compliance' to 'Wellness'

According to the Pokfield Campus website and an HKU Business School news release, the project is positioned as a "Sustainable, Healthy & Smart Campus." Upon completion, it will provide over 9,000 m² of greenery^※, balancing liveability with energy efficiency. The project has also become HKU's first campus project to achieve WELL v2™ Precertification, reflecting the University's new attempt to meet building wellness standards, which go beyond traditional green benchmarks that solely focus on energy consumption and carbon emissions.

According to the Pokfield Campus design page, the project's "healthy building" design references nine foundational metrics under the World Health Organization (WHO) framework—ventilation, water quality, thermal comfort, safety and security, noise control, moisture management, lighting and views, dust and pest control, and air quality. The landscaping design adopts a "sponge city" concept for rainwater harvesting and reuse, featuring multi-level landscaped podiums, vertical greenery, green roofs, and terraces, allowing greenery to visibly connect even on the façades of high-rise blocks. The project is simultaneously pursuing dual certifications under BEAM Plus and the WELL International Standard. The former covers design and construction management, health and wellbeing, site sustainability, and material and waste management; the latter measures a building's multiple impacts on the human body (air, water, nourishment, light, fitness, thermal comfort, acoustics, materials, mental wellness, and community connectivity). In terms of construction methods, the project uses prefabricated building components to reduce construction time and emissions, non-percussive foundation methods, and employs Building Information Modelling (BIM) throughout design visualisation and full lifecycle management^※. This, along with the Modular Integrated Construction method used for the Wong Chuk Hang student residence (see §1 above), is part of HKU's broader push in recent years for "prefabricated and digital construction."

According to the HKU Business School's press release, the Pokfield Campus won Gold in the "Best New Development" category at the MIPIM Asia Awards 2025^※. Founded in 2007, the MIPIM Asia Awards are one of the more significant accolades in the Asian real estate industry. From the Centennial Campus's LEED/BEAM Platinum, to the Wong Chuk Hang student residence's BEAM Plus Provisional Platinum, and now to the Pokfield Campus's WELL Precertification, the ambitions behind HKU's green building ratings are tracing a clear upward trajectory: from "code compliance" to "wellness." The focus is no longer solely on quantitative energy and carbon metrics but is increasingly placing the physical and mental health of occupants at the very core of building design.

# 4.5 Quality Concerns During Construction (2023)

Large-scale projects occasionally attract quality-related controversy during the construction phase, and the Pokfield Campus (then referred to as the Pokfulam Road Campus West Wing Redevelopment) was no exception. In June 2023, according to media reports, a head of an engineering monitoring group publicly raised concerns on social media about the concrete of some structural beams and columns in the three-level basement and the second floor. These surfaces were said to appear "honeycombed" with air pockets and exposed steel reinforcement, leading the individual to question whether "hollow columns" or other structural defects existed, and criticising the standard of workmanship as unsatisfactory. HKU responded by stating it had always attached great importance to the quality of campus works and had seriously followed up on the defects with the contractor. This entry is based on a contemporaneous report from a single news source, and no formal official investigation conclusions have been subsequently published by HKU or an independent engineering body. This article records the existence of the controversy as a matter of record, without drawing a conclusion. Credibility: single source.

# 4-i. Juxtaposing Four Eras: A Complete Evolutionary History of Building Methods

Looking back at the content unfolded across the four sections of this article, the history of architecture on HKU's campus can actually be read as a history of the evolution of building methods, rather than just a history of style:

From "hand-laid brickwork" to "cast-in-place concrete" and on to "factory prefabrication and on-site assembly," HKU's building methods are themselves a microcosm of Hong Kong's construction industry history. The rating standards, too, have moved from a colonial period where none existed, through a "code compliance" era of LEED/BEAM, to today's pursuit of occupant physical and mental well-being under WELL. This line of evolution perhaps explains more about the changes HKU's campus has undergone over the past century than any description of a single building's style.
