ASTM [
5]defines a green building as, “a building that provides the
specified building performance requirements while minimizing
disturbance to and improving the functioning of local, regional, and
global ecosystems both during and after its construction and specified
service life”.
Furthermore “a green building optimises efficiencies in resource
management and operational performance and minimises risks to
human health and the environment”.
To this can be added considerations for community, social equity and
economic viability
[6].
In the context of Hong Kong’s sub-tropical climate and dense urban
high-rise development BEAM regards a sustainable building as one that
is safe, healthy, comfortable, functional, and efficient in the use of
resources.
Environmental Aspects
An environmental aspect is defined in ISO 14004 [
7]as an element of
an organisations activity, products or services than can interact with the
environment. ISO defines ‘environment’ as the surroundings in which an
organisation operates, including air, water, land, natural resources, flora,
fauna, humans, and their interrelation.
Surroundings in this context extend from within the organisation to the
global system. An environmental impact is any change to the
environment, whether adverse or beneficial, wholly or partially resulting
from an organisation’s activities, products, or services.
In the context of BEAM, and green building, the requirements herein
challenge Applicants to lower and reduce these impacts, the ultimate
long term goal being elimination of adverse impacts.
Social Aspects
BEAM Plus is equally concerned with the interaction between the
premises, and their neighbours, neighbouring properties, and the
neighbourhood in general. This methodology encourages Applicants to
reduce negative impacts and rewards efforts that are aimed to improve
the quality of the immediate surroundings to the benefit of the
neighbourhood.
Post-SARs, hygiene has become a major issue in both design and
management of buildings, and the premises within. Indoor air quality as
long been a matter of concern, and together with thermal conditions,
lighting quality and noise is also a comfort issue. Maintaining good
indoor environmental quality (IEQ) depends on design, management,
operation and user understanding of the many factors involved.
Poor IEQ impacts productivity in the workplace. The quality of other
services, such as vertical transportation, can also impact on user
satisfaction and workplace efficiency. However, the needs of users and
the efficiency of buildings need to be balanced against the consumption
of non-renewable natural resources and environmental loading to our
