ABSTRACT
There are worldwide environmental concerns in the present state. There have been
establishments of various movements or campaigns to enhance environmental awareness to the
members of the public. The cases of Hongkong have never been treated as being special or
exception in such cases. In this particular study there is evaluation of the effectiveness of the
implementation of the aspects of green building towards cost reduction in the context of
Hongkong. The focus on the attitude of the occupants was considered due to the fact that they are
familiar with the structures which they occupy. According to this study, there is revelation of the
environmental awareness which is confirmed to be very strong despite the fact that the processes
of evolution are in the embryonic stages. From the perspectives of the occupants of Yeu Shing
building, the features of the green building are relatively beneficial.

INTRODUCTION
The greenhouse gases emitted to the atmosphere as claimed by the Intergovernmental Panel on
Climate Change (IPCC) are enough to create a change in the climatic condition of the ecosystem.
The IPCC has set standards to ensure reduction of environmental pollution, and therefore,
attempts have been made by countries to lower their levels of emitting carbon gases to comply
with the set standards as they carry out their processing and manufacturing activities. Records
state that large volumes result from the construction industries compared to other industries. The
set standards and designs for the green building to enhance energy operation of the building
alongside the represented energy efficacies, and reduce the amounts of wastes and used
energy(Steinemann Wargocki and Rismanchi 2017).
Adopting green building as a construction technique may make it possible to easily attain a
sustainable construction within industries. And for this sustainability, construction industries
within the past few years have made attempts to adopt the practice of green building. It is all
concerned with efficiency of the resources, performance of the structure, as well as the impacts
of its stages. Smart structures with the systems of integrated building technology as the core are
mainly of concern to efficient operation and construction as well as improved management and
activities of the residents. “Green” building or Sustainable construction and systems of integrated
building technology greatly differ from one another in terms of commodities (Chegut, Eichholtz
and Kok 2014).

There is rapid development in green buildings facilitated by factors like the advancing problems
within the environment, a relentless increase in the demand for quality environment, initiation
and progress of the different techniques of green building, continuous usage of supplementing
“evaluation mechanism of green building” alongside supportive rules and policies. It is of
common knowledge that green building is the basic idea and the actual motives for the
development of green building, a bearable concept of development, and mainly highlights the
acclimation to the environmental states, issues and times (Dwaikat and Ali 2016).
It is however sorry to say that the concept of green building implementation in the sector of
agriculture including storage of forage, livestock barns and greenhouse still remain low. Similar
techniques used by green building were implemented by different studies which however did not
attain the core of the concept or either full address of this concept as well. The main aim of this
paper therefore is to introduce to the agricultural sector the concept of green building alongside
the associated features together with the distinct aspects of economy, engineering and
environment. The paper summarizes by a discussion on the likelihood of merging the two
concepts, i.e., agriculture and green building.
RESEARCH OBJECTIVES
In order for this research work to become a success, the following research objectives were laid:
i. To have a comprehensive introduction of the “green building” concept
ii. To objectively review “green building” situation in Hongkong
iii. To analyze the expected results from the structures considered as “green buildings”
iv. To properly evaluate green building performance in the context of Hongkong
v. To gather as well as evaluate the attitudes of occupants towards green building.

vi. To provide further recommendations on the areas of improvements as per the green
building technology in Hongkong.
LITERATURE REVIEW
The Exact meaning of green building
Currently, different terminologies like ecological design, sustainable architecture, and green
building, have been used together with various versions of the same to refer to friendly designing
ways of the environment, building as well as performance implemented to help generate a lasting
healthy environment. There terminologies are however indefinite and their implementation
results into great uncertainties.
The definition which was given by a scholar concerning green building is “the construction
process which aims at reducing the amount of resources used, lower the level of pollution to the
environment to generate a sustainable or bearable surrounding to the residents.” As a concept, it
unveils the high performance level at the engineering, economically and environmentally. These
comprise of better quality of indoor air, efficiency and conservation of energy, productivity and
health of the individual, and efficiency of materials as well as resources.
Other scholars observed green building as design output which mainly aims at improving
efficient energy consumption, materials as well as water usage – and at the same time minimize
the effects resulting from the construction process on the environment as well as the health of
individuals during the phase of construction, by provision of proper design, construction,
location, maintenance and performance. This definition was supported by a number of scholars
which stated that the concept of green building is a philosophical design result mainly aiming at
improving the efficiency in the use of resources. Other scholars recorded that the concept usually

observed as the possibilities resulting from natural ventilation, are the currently major research
concerns and alleviation issues on the change in climatic conditions. The table below presents
the differences between the ancient structures also known as the “non-green buildings” and the
“green buildings.”
Table1: Comparing the differences between non-green buildings and the green buildings
(Steinemann Wargocki and Rismanchi 2017)
Green building also differs from “eco-construction” – a sub concept within the entire concept of
green building. The definition given by a grant on eco-construction based on the development of
network alongside implementing use of natural resources in building the Mediterranean Cluster
on eco-construction and Sustainable Development is, an integrated and holistic tactic focusing on
increasing access to better residing places mostly for the locals, at the same time certain efficient
use of natural resources and to develop a heritage construction on culture and architecture.
Construction eco-innovation results into the sales of products, availing advanced elucidations
and services like bioclimatic architecture, while focusing on the use of available natural
resources and at the same time focusing on the technical know-how of the enterprise as well as
of the individual (Zuo and Zhao 2014.).

Green building and the surrounding
Persistent of the earth calls for the necessity of “Sustainable Development”, while for the life
persistence, a “healthy and comfortable” state is necessary. Also, the current world is under siege
looking into the deficit supply of natural resources and energy, whereby is become very difficult
to eliminate the problem of global changes in the climatic conditions. Various countries have
implemented the concept of green building as a way of creating a sustainable environment and
preserving the little available natural resources. This revolves around reduction in degradation to
the environment resulting from processes of construction and facilitation a shift to a clean and
suitable ecosystem (Wu et al.2016).
The sector of construction is associated with the largest emission of greenhouse gases, for
example, the large amounts of energy used in processes like device operation, heating and
lighting releases more carbon dioxide. In the past decades, a faster growth has been observed in
green building. The construction gages within the environment have the ability to unveil the
benefits as well as the effects of construction to the environment. These pointers also expedite
environmental concerns of management at the phases of decision making. The wide recognition
of the pointers by a number of decision making departments at the distinct stages of construction
is very vital in case the obligations are optional, but rather freely implemented in bottom-up
initiatives.
Present State of Green building concept in Hongkong
In the year 2001, there was implementation of the green building policy by the Hongkong
Government. Part of the policies included exemption from the gross floor area which is
commonly known as GFA in the case of the developments on the green features. There was a
piece of advice by the administration t the council following a meeting which was held on 26
April 2006 to have the effectiveness of various incentives reviewed. This was expected to go

alongside introduction of other measures which can potentially green materials use as well as
provision of green facilities to the structures which are adopting the technology. This was
considered as an effective response to those concerned with the savings of energy, use of the
renewable energy, sorting of wastes as well as roof greening (Liu, and Lin 2016). Hongkong
government has been keenly evaluating as well as monitoring green features provision since the
introduction of the measures outlined above. The department of the building has been getting
support as well as positive feedback from the review which was done initially. The processes of
evaluation actually discovered that the calculation of GFA exemption is actually associated with
other additional problem. Part of the problem include the increase in the density as well as
density of the building hence the surrounding environment is affected greatly.
A combination of passive and active systems of solar as well as electricity of night time has been
relied upon for the supply of cooling and heating demands. The paper therefore seeks to provide
information of the site and climate, basic decisions and options design, strategies of energy
saving and finally data of energy end use.. It therefore allowed for the presentations as well as
evaluation of sufficient data of performance. Added to part of realizing the concept of efficient
solar residential house, some initial design and general results problems have been discussed.
RESEARCH METHODOLOGY
Despite the fact that the term green building g is not new or the concept itself is never new to the
public generally, the realization as well as understanding of the performance has never been easy
for tye common man with no experience of living in the green building. Interestingly, even those
individuals who are privileged to be living in the green buildings, there is no surety that their
needs are completely and fully satisfied. In order to meet the objective of this particular study
this is assessment of the effectiveness of Implementation of Green Buildings in relation to cost
