The purpose of this paper is to identify the most influential buildings elements in term of the cost for timber restoration works.

The research employed the case studies methods with questionnaires surveys. Two case studies were chosen and questionnaire surveys were distributed to contractors and consultation companies. The cost was identified based on the elemental cost analysis of historic timber buildings.

The restoration of historic timber buildings in Malaysia has grown rapidly, especially in the UNESCO world heritage sites, Melaka and Penang. Data obtained on the restorations of timber buildings show that the most influential elements were upper floors, roofs and walls. Termites’ invasions and the lack of building analysis were found to be the major issue in timber restoration works. In addition, the availability of timber material contributed significantly to the increase of cost for restoration works.

The cost for every element was identified and was used as a reference for new restorations projects of historical, timber buildings. This paper also highlighted the causes for the problems and the factors affecting the cost of timber restoration works. These data are useful information, especially for surveyors and contractors who are involved in the restoration of historic timber buildings. Maintaining or replacing these elements with other material can help to minimise the restoration cost of timber buildings in Malaysia.

Timber waste from construction is downcycled into non-structural products, incinerated for energy generation or disposed of in landfills. Existing literature highlights that the use of reprocessed timber for structural purposes is limited. Therefore, this study aims to focus on identifying factors limiting reprocessed structural timber (RST) uptake amongst construction professionals in Australia.

Current literature shows that the use of reprocessed materials (RMs) depends on user-specific personal factors and broader contextual factors. Therefore, data collection and analysis were based on the attitude-behaviour-context (ABC) theory, which affirms this relationship between personal and contextual factors in determining pro-environmental behaviours (PEBs). A qualitative research approach was adopted, considering limitations with industry expertise and the need for developing an in-depth understanding of limiting factors. Twenty semi-structured interviews were conducted amongst construction professionals experienced in using reprocessed materials, while the thematic analysis technique was used to analyse interview findings.

Personal factors that limit the uptake of RST include negative cost and quality perceptions, risk appetite, the tendency to maintain the status-quo, limited decision-making capability and lack of skills and expertise, while contextual factors include higher prices, poor and uncertain quality, limitations with information availability, under-developed supply and drawbacks in the regulatory environment.

The current study is amongst the first to explore the uptake of reprocessed timber for structural uses in Australia. The findings can be utilised to create a stronger demand for RST by directly addressing personal and contextual factors that constrain construction professionals from using RST.

The purpose of this paper is to propose a more carbon efficient alternative design using engineered timber components over reinforced concrete elements to a recently completed non-residential building located in Tallinn, Estonia. Also to promote building materials that have proved to have lower embodied carbon and energy.

The paper is based on data collected from the original project drawings, embodied carbon and embodied energy values of construction materials under comparison which are based on Inventory of Carbon & Energy database and on the research conducted in Finland that focussed on wooden building products. The engineered timber solution is designed in accordance with relevant regulations and laws including requirements for fire safety and sound insulation.

Buildings embodied carbon and embodied energy can be reduced by using proposed engineered timber materials.

The outcome of current research is limited and applies only to the reference building and its proposed alternative, therefore it should be taken into consideration before any use. Still it provides clear information that using more carbon efficient materials can significantly reduce the carbon footprint of a building.

The outcome can be used as a tool promoting materials with a lower embodied carbon and energy in public procurements.

This study comparing buildings enclosure system alternatives as a whole by allowing to choose more environmentally friendly solution is the first in Estonia.

The paper aims to understand Finnish architects' attitudes towards the use of timber as a structural material in multi-storey (over two--storeys high) residential construction.

The study was conducted through a literature survey mainly including international peer-reviewed journals and similar research projects. Furthermore, the literature survey informed the generation of the web-based survey questionnaire design to gather information on architects' perceptions, attitudes and interest in the use of wood in multi-storey (over two-storeys high) residential buildings.

The paper's findings are as follows: (1) respondents perceived the most important advantages of wood as a lightweight, local and ecological material; (2) wood construction (compared to concrete) included perceived concerns about it being more costly and needing more complex engineering and (3) respondents had a favourable overall attitude towards the use of wood particularly in low-rise residential construction, whilst their perception of tall housing, including timber ones, was mostly negative.

No studies have evaluated the use of wood in tall residential buildings and architects' perceptions in Finland.

Traditional industry was initially built with kinship, cultural value, and unique characters representing a particular system of production. However, current industry challenges pressurized traditional industry bond of primordial system with the need of adaptations to survive. Some traditional industry may resist the twenty-first-century challenges and pressures, but many of them are transforming their cultural and production characters to adapt modern business competitions. Indonesian traditional furniture industry Jepara has their familial system of productions which constitute “flexible specialization” where particular kinship and work contract created from a very specialized household small-scale furniture producer. However, this production system in fact struggles and is contrasted with the community needs to survive in the industry. The likely occurring progress of traditional industry are then remaining on the senior members of the industry to preserve knowledge which has empowered over many generations, while the younger generations consider transforming their ability for survivability and better financial rewards.

This chapter is the further elaboration of how Indonesian rural traditional furniture industry in Jepara presents its survivability and whether it is sustainable. This chapter exemplifies participants’ quotes and statements which create anxiety toward their future, cultural value, bond of industry kinship, and doubting their ability to withhold global and local pressures.

The purpose of this study is to describe life cycle cost (LCC) and life cycle assessment (LCA) evaluation for single story building house in Malaysia. Two objective functions, namely, LCA and LCC, were evaluated for each design and a total of 20 alternatives were analyzed. Two wall schemes that have been adopted from two different recent studies toward mitigation of climate change require clarification in both life cycle objectives.

For this strategic life cycle assessment, Simapro 8.3 tool has been chosen over a 50-year life span. LCC analysis was also used to determine not only the most energy-efficient strategy, but also the most economically feasible one. A present value (PV)-based economic analysis takes LCC into account.

The results will appear in present value and LC carbon footprint saving, both individually and in combination with each other. Result of life cycle management shows that timber wall−wooden post and beam covered by steel stud (W5) and wood truss with concrete roof tiles (R1) released less carbon emission to atmosphere and have lower life cycle cost over their life span. W5R1 releases 35 per cent less CO₂ emission than the second best choice and costs 25 per cent less.

The indicator assessed was global warming, and as the focus was on GHG emissions, the focus of this study was mainly in the context of Malaysian construction, although the principles apply universally. The result would support the adoption of sustainable building for building sector.

It is a well-known fact that global warming is the extraordinary threat facing the world. The main reasons of these are human activities. Human beings have been contributing to the global warming in different ways for many years. Right material and product selection are some of the most important factors in the process of eliminating the negative effects of constructions on the natural environment and users. The life cycle of building materials involves the processes in which the products are extracted from the source. These processes are the stages of production, transportation, construction, use, demolition and destruction. Making wrong decisions in the selection and use of building materials may cause negative effects in the environment. The major purpose of this study is to to examine the embodied energy of of the traditional and comtemporary building materials according to the characteristics of the local climate. It will answer the question of; “What the embodied energy of a house was in the past and now” in Northern Cyprus. It will help to find out building materials with low embodied energy. There is no published database prepared for or in Northern Cyprus. In order to measure and evaluate the embodied energy of buildings and construction products in the world, there are no integrated systems in the Northern Cyprus at this point, while different countries have unique systems depending on the environmental, economic and social conditions of those countries. Measuring and controlling the environmental performance of environmental development is essential for the sustainable development of the Northern Cyprus.

By using the The Inventory of Carbon & Energy (ICE) program the embodied carbon statuses, embodied energy and transport energy and manufacture energy were discussed for each building material. As a result of this research it was found that locally produced or locally existing materials do not always give the best result in terms of embodied energy all the time. The energy consumption of building materials used in buildings and their associated carbon emissions will assist in the selection of environmentally friendly materials.

The purpose of this paper is to study the possibility of promoting certified timber coming from sustainable managed forests, in order to support Greek enterprises and the institutions of the Greek timber sector involved to apply effective green marketing methods and policies.

Based on a prototype questionnaire, specifically structured for the aim of the research, 55 responses were collected from Greek timber enterprises in April 2009. The questionnaires were processed and analyzed with the statistical program SPSS of ver17.0, using descriptive statistics and correlation analysis. The main purpose was the investigation of knowledge, use and promotion of certified timber that emanates from forests under sustainable management, thus planning the green marketing.

The Greek enterprises of the timber sector expressed a great interest in the protection of forests all over the world, ranging from illegal loggings to their rational management. At the same time, in their overwhelming majority, they strongly support the certification of the sustainable management of Greek forests. These enterprises believe that the movement of green buildings has also reached Greece, albeit at a slow pace, and forecast that green consumers are prone to offer an additional percentage of about 6 per cent on price, in order to buy certified timber products. Companies trust to a high degree most institutions of higher education (universities and technological institutions) for the promotion of certified timber products and propose their publicity through newspapers and magazines, as well as through internet portals of close contact. Finally, the paper discusses reflections and forecasts on the growth of this new market of timber.

The results offer precious knowledge on the market of certified timber and its future developments in the following five years, which can assist both enterprises and the institutions involved in strategy forming and decision making, in order to gain an important share of the market of green consumers. The paper also proposes effective green marketing applications.

This is the first research on green marketing and the promotion of certified products of timber in the Greek market, while similar work is very limited even at an international level.

Traditional construction materials and methodologies are often perceived to be unproductive, labour-intensive and detrimental to the environment. Mass-engineered timber (MET) is a new structural material that is capable of overcoming numerous issues that otherwise affect the built environment. This study was formulated to assess the current attitude and perception of young Singaporeans towards the concept of Engineered Timber Residential Buildings (ETRBs).

The study employs the mixed-method approach. Questionnaires were used as the primary mode of data gathering. These were disseminated to Singaporeans between the age of 18 and 35 years. A total of 179 valid responses were gathered. Semi-structured interviews were subsequently conducted with six individuals with different demographics in order to gain further insightful opinions and to allow cross validation of responses.

Statistical analysis revealed that 80% of respondents were willing to accept ETRBs, but a lack of awareness and knowledge of MET and the presence of misconceptions, such as an association with deforestation, may present concerns. The study also revealed that individual acceptance of ETRBs is not affected by demographics.

The production of MET involves lower overall carbon emissions than that of conventional materials, and this also allows adoption of the Design for Manufacturing and Assembly (DfMA) concept and offers the benefit of carbon sequestration. Residential buildings are the second most common building type in Singapore; significant benefits can be gained if MET is used as the primary material for residential buildings. In general, young stakeholders in Singapore welcome the concept of ETRBs, despite possessing uncertainties about ETRBs—understandable given that the material lacks a track record of usage. Public authorities are thus advised to explore the feasibility of materialising the concept of ETRBs as an option for public housing.

Local dwellings of Bangladesh have specific environmental characteristics. These dwellings extensively use locally available materials and construction techniques. Therefore, carbon footprint (CF), as a prominent environmental parameter, is greatly affected by construction materials and techniques. Nonetheless, scientific justification is limited to evaluate CF of these dwellings in Bangladesh according to different local construction materials. The main purpose of this study is to evaluate different rural dwellings’ CF for both construction and operational phases toward the development of low carbon society in Bangladesh.

For evaluating CF, literature review and field studies were conducted to specify and categorize cases. An intensive field monitoring and occupant's survey were performed during summer. A widely recognized compliant database and assessment tool “Ecoinvent v3” was used based on International Organization for Standardization (ISO) 14040 and 14044. Quantitative and qualitative data were collected to evaluate constructional and operational stages of carbon emission using hybrid methods formed by process-based and economic input–output life cycle analysis (EIO-LCA) approaches.

The study indicates that different building materials significantly impact on dwelling's amount of carbon emission according to construction techniques. Brick dwelling's construction stage carbon emission was nearly 3.86 times higher than timber, whereas, 6.75 times higher than mud dwelling. In terms of operational stage, local brick dwelling emits higher carbon compared to others relating to occupants’ lifestyle and activities.

This study will contribute to helping professionals and policy-makers to interpret and evaluate architectural design and construction processes for improving low-carbon dwellings in Bangladesh.
