Promoting a Green Working Culture

GRI 102-44

In light of the pressing climate and environmental changes, ArchSD does not only leverage our expertise in architecture to build for the city's sustainability and climate-resilience, but also shoulder our indispensable responsibilities as a government department to create a green workplace. We developed a departmental Quality, Environmental, Health and Safety Policy with commitments to achieving pollution prevention, as well as and energy and natural resources consumption reduction. We also focus on fostering employee environmental awareness through programmes and daily engagement to optimise our sustainability efforts.

Alongside with the policy, our Integrated Management System (IMS) has been serving as the foundation of our exhaustive environmental and energy management (ISO 14001 and ISO 50001), occupational health and safety (ISO 45001) and quality management (ISO 9001). By doing so, we benchmark and attach ourselves to international standards. The systematic approach also allows us to formulate guidelines, procedures and strategies for the monitoring and improvement of energy, waste, water and indoor air quality performance.

The concerted efforts from our management and staff has earned ArchSD once again the Hong Kong Green Organisation Certificate (HKGOC). The consecutive recognition from the Environmental Campaign Committee serves as a testimony and future motivation to our conscientious contributions to the environmental protection in workplace.

Energy Use and Carbon Emission Management

ArchSD clearly understands the need to contributing and acting in response towards the government's long-term plan to combat climate change. Acknowledging energy consumption, principally electricity consumption, is the primary source of our carbon footprint, we manage our consumption practices across our operating premises to ensure efficient energy utilisation.We continue to monitor our electricity use and explore different energy efficiency measures, such as lighting retrofitting works at our offices, to minimise the related greenhouse gas (GHG) emissions.

In addition to the HKGOC regarding overall environmental performance, ArchSD is pleased to maintain its 'Class of Excellence' Energywi$e Certificate under the same scheme in the reporting year. We are proud that our energy saving efforts have continued to gain wide recognition from the industry and general public.

ArchSD formulates proactive measures to incorporate the elements set out in the Hong Kong Climate Action Plan 2030+ published by Environment Bureau, including a set of city-wide carbon emission reduction targets and actionable items. In order to understand our performance in direct and indirect GHG emissions and move towards the common goal, we regularly conduct carbon audits to quantify our carbon footprint. The audits are carried out in accordance to the international standards Greenhouse Gas Protocol and making reference to guidelines published by the Environmental Protection Department (EPD) and the Electrical and Mechanical Services Department (EMSD). Three major GHGs, namely CO2, CH4 and N2O, induced from our electricity and fuel consumption are tracked closely and taken into considerations in the audits. Other operational data are also incorporated into the calculation to truly reflect our performance on a consistent and measurable basis.

Carbon Emissions Produced by our office located at the Queensway Government Offices

The carbon emissions produced by our office located at the Queensway Government offices (QGO) have remained stable over the last past five years.






FY2018-19 [3]

Direct Emissions (Tonnes of CO2e)






Energy Indirect Emissions (Tonnes of CO2e) [1]






Other Indirect Emissions (Tonnes of CO2e) [2]






Total (Tonnes of CO2e)






[1] - A territory-wide default emissions factor was used to calculate these emissions.

[2] - The figures were calculated by measuring the actual usage of fuel in mobile sources and paper consumption (A3 and A4) and waste paper collected for recycling at QGO.

[3] - The slight increment in total carbon emission recorded in FY2018-19 was due to the increase in fuel usage of mobile sources combustion for transportation needs to remote project sites; the increase in overall electricity consumption of commonly used facilities in QGO; and the decrease in paper recycling, which ArchSD has been persuading electronic digitisation and actively promoting CO-i in our office operation.



Carbon Emissions Produced by our office located at APB Centre

Upgrades made to the building's air conditioning system, regular maintenance and the application of various energy efficiency features at the APB centre resulted in a gradual drop in carbon emissions of about 13% in 2019 compared to 2015

[4] - A territory-wide default emissions factor was used to calculate these emissions.



Waste Management

In support of the government's advocacy on waste management, ArchSD encourages waste reduction at source and promotes active recycling across our branches and offices. Green housekeeping guidelines are issued to disseminate information about appropriate practices in waste reduction, recycling and handling. For example, the guidelines set out principles for paper consumption and reduction to avoid unnecessary wastage. At the APB centre and QGO, collection facilities are set up for the collection of various recyclables, including but not limited to wastepaper, plastic bottles, used toner cartridges, aluminium cans and used CDs.

Additionally, we formulate annual targets to drive improvement progress, together with close monitoring on the implementation of different waste management programmes.

Our efforts in responsible waste management has also earned us a 'Class of Excellence' Wastewi$e Certificate for consecutive years under the HKGOC Scheme.

Water Management

ArchSD is committed to conserving water resources by efficient water usage and deploying different water saving devices. The installation of sensor taps and dual flush cisterns have helped avoid excessive water consumption in workplace. Our potable water and flushing water consumption is closely tracked while maintenance work is regularly arranged to ensure proper functioning of the water system.

In addition, our general circular entitled 'Measures of Green Housekeeping' which outlines good practices is circulated to raise our staff’s awareness of water conservation.

Indoor Air Quality Management

Regarding indoor air quality (IAQ) as one of the material conditions of a pleasant and healthy working environment, we adhere to good management practices suggested in the guidelines published by the EPD. To play a key role in promoting green and comfortable workplace, we have supported the EPD's voluntary IAQ Certificate Scheme to pursue a good performance in IAQ. The IAQ performance is assessed by accredited bodies regularly. During the reporting year, both APB Centre and QGO were again awarded 'Basic Level' IAQwi$e Certificates.

The APB Centre and QGO both received the 'Basic Level' IAQwi$e Certificates

Cultivating Environmental Awareness

ArchSD does not limit our efforts in resource efficiency improvement and pollution prevention, but also nurtures environmental awareness across our workplace and invites our staff to join the department's long-term environmental sustainability journey. We wish to infuse a green culture into our staff's working style and thereby to shape their roles and responsibilities. To this end, we constantly disseminate environmental messages and reminders of good practices via the intranet, emails and other communication channels to them.

We organise activities and training sessions in relation with different environmental initiatives, global issues and trends for our staff and encourage their proactive participation in events held by external organisations. During the year, our staff took part in over 43 events. In addition, a designated team of 71 Green Wardens has been established to facilitate the spread of green messages and provide assistance in implementing ArchSD's green programmes and activities. We also support out staff to gain professional qualifications in diverse environmental domains, for instance, a group of our staff members maintain the BEAM Pro green building related qualifications. With the considerable amount of resources and time we devoted, we can expect a raising environmental awareness and knowledge at all levels within ArchSD.
