E1 Consumption of Resources and Energy per HK$1,000,000 Gross Value of Construction Works

E1.1 Whole Industry

Category: Whole Industry

Sector: N/A

The consumption of resources and energy per HK$1,000,000 gross value of construction works aims at indicating the environmental impacts of construction works. The consumption of resources and energy in the Whole Industry fluctuated between 2001 and 2012. In 2008, it reached the highest level, followed by a decrease in 2009 and 2010, and rebounded in 2011 and 2012.

Note 1 –

Consumption of resources and energy per HK$1,000,000 gross value of construction works

=	Consumption of materials and supplies, fuels, electricity and water, and maintenance services (whole industry/ respective categories or sectors)
	Gross value of construction works performed (All construction activities/ respective categories or sectors) / 1,000,000 (in nominal term)

Note 2 –

The construction works of all construction activities include construction of buildings, civil engineering, demolition & site preparation, building services installation and maintenance activities and building finishing & other specialised construction activities.

Note 3 –

Consumption of resources and energy and Gross value of construction works performed were obtained from the Key Statistics on Business Performance and Operating Characteristics of the Building, Construction and Real Estate Sectors published by Census and Statistics Department (C&SD).

Note 4 –

As confirmed by C&SD, the values in the report are in nominal term.

Note 5 –

“Civil works” were based on “Civil Engineering” in the publication. “Civil Engineering” includes construction of civil engineering projects and miscellaneous civil engineering works.

Note 6 –

“New Building works” were based on “Construction of Buildings” in the publication. “Construction of Buildings” includes construction of buildings includes erection of architectural superstructures, structural steel framework erection, other new building construction, structural alteration & addition works, erection of minor architectural superstructures, erection of temporary structures and combined & other miscellaneous new building construction works.

Note 7 –

The data for 2013 is not available.

Note 8 –

In the publication of 2009, C&SD adopted the revised Hong Kong Standard Industrial Classification (HSIC), i.e. HSIC Version 2.0, to reflect significant changes in the structure of the Hong Kong economy and the emergence of new economic activities. Due to the change in classification, data of New Building Works and Civil Works for 2001 to 2006 are not available.

E1.3 – New Building Works

Category: New Building Works

Sector: N/A

The consumption of resources and energy in the New Building Works gradually increased since 2007. In 2012, it increased by 5.9% compared to a year before.

E2Building Energy Use

E2.1 Residential Building

Category: N/A

Sector: N/A

The building energy use in the Residential Buildings showed a mild increasing trend since 2002 and kept at a high level in the recent years.

E2.2 Commercial Building

Category: N/A

Sector: N/A

The building energy use in the Commercial Buildings had been increasing gradually since 2002. The energy use in 2012 increased by 1.9% compared to a year before.

E2.3 Industrial Building

Category: N/A

Sector: N/A

The energy use in the Industrial Buildings showed a decreasing trend since 2002 and remained steady in 2011 and 2012.

Note 1 –	The “building energy use” was based on “energy end-use data” which includes “Electricity”, “Town Gas and Liquefied Petroleum Gas”, “Oil and Coal Products”. The energy end-use data from year 2010 also includes renewable energy data.
Note 2 –	The energy end-use data was based on the Hong Kong Energy End-use Data published by Electrical & Mechanical Services Department.
Note 3 –	The data for 2001 and 2013 are not available.

E3 Construction Waste (tonnes) to Landfill per day per HK$1,000,000,000 Gross Value of Construction Works

E3 Whole Industry

Category: Whole Industry

Sector: Whole Industry

The construction waste to landfill is aimed to show the construction and demolition waste generated from construction works. The disposal of construction waste to landfills has reached a low level since 2006. In 2012, it decreased by 11.6% compared to a year before.

Note 1 –

Construction waste (tones) to landfill per day per HK$1,000,000,000 gross value of construction works

=	Overall construction waste (Average daily quantity)
	Gross value of construction works (Whole Industry / Respective categories or sectors) at constant (2000) market prices)/ 1,000,000,000

Note 2 –

Overall construction waste was obtained from Monitoring of Solid Waste in Hong Kong published by Environmental Protection Department.

Note 3 –

Overall construction waste is a mixture of waste or surplus materials arising from construction activities such as site clearance, excavation, refurbishment, renovation, demolition and road works. It also includes waste concrete that is generated from concrete batching plants and cement plaster/ mortar manufacturing plants not set up inside construction sites. Overall construction waste may comprise a fraction of inert materials such as debris, rubble, earth and concrete, which, after proper sorting, can be recycled for use in site formation, land reclamation and construction.
