The world today is faced with climate change issues and due to the activities man has been involved in over the years. Worldleaders have become very concerned with this and lot of measures are been laid down to mitigate this. The built environmentis a major contributor since its construction process, materials used and even the daily operation uses a lot energy which is amajor concern. Architects are therefore challenged with creating a balance between their traditional aesthetics of buildingsand energy efficiency. This research therefore seeks to find out how this balance can be achieved in the tropics through theuse of different window pane properties. The study therefore sought to identify developments of windows with regards to theirpane properties to see how both aesthetics and energy efficiency can be achieved. Literature was reviewed to find out thecurrent situation and then a case study building analysed for results. The case study buildings were then modified to see theeffect of each modification. Comparative analysis was done with the original buildings and the modified buildings and it wasfound that reflection was a key to achieve both aesthetics and energy efficiency. Other factors had impact and influence onthe aesthetics and energy efficiency but reflection stood out of the lot.

Climate change is a financial factor that carries with it risks and opportunities for companies. To support boards of directors of companies belonging to all jurisdictions, the World Economic Forum issued in January 2019 eight Principlescontaining both theoretical and practical provisions on: climate accountability, competence, governance, management, disclosure and dialogue. The paper analyses each Principle to understand scope and managerial consequences for boards and to evaluate whether the legal distinctions, among the various jurisdictions, may undermine the application of the Principles or, by contrast, despite the differences the Principles may be a useful and effective guidance to drive boards' of directors' conduct around the world in handling climate change challenges. Five jurisdictions are taken into consideration for this comparative analysis: Europe (and UK), US, Australia, South Africa and Canada. The conclusion is that the WEF Principles, as soft law, is the best possible instrument to address boards of directors of worldwide companies, harmonise their conduct and effectively help facing such global emergency.

This paper examines counterfactual display in the valuation of carbon offsetting projects. Considered a legitimate way to encourage climate change mitigation, such projects rely on the establishment of procedures for the prospective assessment of their capacity to become carbon sinks. This requires imagining possible worlds and assessing their plausibility. The world inhabited by the project is articulated through conditional formulation and subjected to what we call “counterfactual display”: the production and circulation of documents that demonstrate and con!gure the counterfactual valuation. We present a case study on one carbon offsetting reforestation project in the Democratic Republic of Congo. We analyse the construction of the scene that allows the “What would have happened” question to make sense and become actionable. We highlight the operations of calculative framing that this requires, the reality constraints it relies upon, and the entrepreneurial conduct it stimulates.

A number of horrific failures of both public and privately owned dams in recent decades has triggered serious concern over the safety of dams throughout the world. However, in Australia, although much Government attention is being devoted to the medium- to large-scale dams, minimal attention is being paid to the serious potential cumulative, catchment-wide problems associated with smaller private dams. The paper determines how to consider addressing hazardous private dam safety issues generally through a comparative analysis of international dam safety policy/law systems. The analysis has identified elements of best and minimum practice that can and do exist successfully to provide deserved assurance to the community of the proper safety management of hazardous private dams at both the individual and cumulative, catchment-wide levels. These elements provide benchmarks that enable ‘appropriate’ legislative arrangements to be determined for different jurisdictional circumstances as illustrated with an Australian policy-deficient case study.

Over many decades, buildings have been recognised as a significant area contributing to the negative impacts on the environment over their lifecycle, accelerating climate change. In return, climate change also impacts on buildings with extreme heatwaves occurring more frequently and raising the earth’s temperature. The operation phase is the most extended period over a building’s lifespan. In this period, office buildings consume most energy and emit the highest amount of greenhouse gas pollution into the environment. Building upgrading to improve energy efficiency seems to be the best way to cut pollution as the existing building stock is massive. The paper presents an economic analysis of energy efficiency upgrade of buildings with a focus of office buildings. The paper identifies upgrading activities that are commonly undertaken to upgrade energy efficiency of office buildings and a case study of three office buildings in Sydney, Australia has been used to analyse the results. The upgrading activities can improve the energy performance of the case study buildings from 3 stars to 5 stars NABERS energy rating in compliance with the mandatory requirement in the Australian government’s energy policy. With the potential increase in energy price, energy efficiency upgrading will become more affordable, but currently, most of them, except solar panels and motion sensors show a negative return and would not be undertaken if they did not also contribute to higher rental income and an increased life span of the building. The upgrading discussed in the paper represent a potentially attractive alternative to demolition and building anew.

Climate change is increasing the occurrence of disastrous events in the world, but several disparities in population vulnerability are being registered. One of the causes of these variances is different public risk perception also due to the degree of education and knowledge of the population. In this study, some of the results obtained in a risk perception survey are presented. The survey was carried out in an area of Calabria (Southern Italy) hit by geo-hydrological events that have occurred in recent years with damage to roads, tourism facilities and private houses. A statistical interpretation of the results highlights the importance of education and knowledge to risk perception on the part of the population investigated.

Ornamentation is one of the elements in mosque which is almost considered as a compulsory element by the common people. Most of these ornaments are using the precedent from Middle East, such as geometry, floral and arabesque (Utaberta, 2014). Many architects are using revivalism approach of past architectural building such as the Putra Mosque, glorious son of Malaysia. The Putra mosque adopts distinct Islamic architecture that calls on a foreign eclectic revivalism (historicism design approach) of the Persian (Iranian) vocabulary found during the glorification of Safavid period (Utaberta 2012). Ornamentation in Islamic building has recorded in many books. describe that one of the first ornamentation in Islamic Building found in Persia which is using revivalism approach in designing ornament in its column. Ornamentation is the key element that is used in most mosques all over the world. The aim of this writing is to provide the Charles Jencks’s approaches to evaluating ornamentation system in mosque especially in Malaysia.

Maritime transportation has been a cost-effective option among other transport modes. Meanwhile, this demand has been increasing day by day because of the expanding global economy. The ships are one of the most important transport and trade vehicles in the world; 90% of the world trade is carried out by maritime transport, and this sector plays a crucial role in climate change and global warming because it is one of the key sectors leading to emissions of carbon dioxide, the main greenhouse gas (GHG). In other sectors that lead to CO2 emissions, i.e., energy production, manufacturing industry, and heating in residences, energy efficiency has been improved and emissions have been reduced significantly. However, there has been no net reduction in the transport sector; total CO2 emissions have also increased because of the continuous increase in freight and passenger traffic, although efficiency has increased. Increasing the energy efficiency of a ship allows for fuel consumption reduction and GHG emissions. In this study, the energy system of a chemical tanker ship was analyzed and then modeled by using the long-range energy alternatives planning system, a widely used platform for energy policy analysis and climate change mitigation assessment, including a comprehensive energy flow diagram, namely, reference energy system. A base scenario was developed, and the ship’s energy system was convenient to be analyzed and evaluated in terms of technical, economic, and environmental aspects, including low-emission development strategies, to comply with marine engine regulations of the International Maritime Organization.
