Reducing Energy

Green building conveys undeniably numerous benefits to the environment, social and economic aspects. The most substantial benefit of green building is energy conservation. Green roofs and green walls are amongst the green components that are synonymous with green building. These green components are similar in nature as both are based on the concept of vegetation coverage on buildings. Vegetation is a well-known natural medium that performs the photosynthesis process where it releases molecular oxygen and removes carbon dioxide from the atmosphere. Many studies have proved that these two green components are efficient in reducing energy consumption of a building. Therefore, this study aims to examine and compare the annual energy savings conveyed by green roofs and green walls on residential buildings in Malaysia. The findings indicated that green walls provide greater annual energy savings than green roofs. The result shows that green walls are able to provide higher annual electricity savings for residential buildings at RM166 compared to green roofs, which provide savings of only RM139.

TOD is designed for public transport passengers and pedestrians to provide comfort and safety in creating a healthy lifestyle. Green Building Council Indonesia (GBCI) is needed as a reference and assessment to optimize building design. The purpose of this paper is to determine the extent of the green building concept applied, calculate the met and unmet Greenship criteria, also measure the GBCI Greenship predicate obtained. The data collection method used is project data and data analysis with the index scale method on Greenship New Building version 1.2. The results showed that in Appropriate Land Use categories credit are 11 points of 17 maximum points with percentage 64,71%, the Efficiency and Energy Conservation categories credit is 1 point of 26 maximum points with percentage 3,85%, the Water Conservation categories credit are 9 points of 21 maximum points with percentage 42,86%, the Source and Material Cycle categories credit are 2 points of 2 maximum points with percentage 100%, the Health and Safety Space categories credit are 4 points of 5 maximum points with percentage 80%, and the Building Environmental Management categories credit are 4 points of 6 maximum points with percentage 66,67%. The final results of TOD Pondok Cina Project are 31 points of 77 maximum points with percentage 40,26% which categorized as Building with Bronze predicate.

<p>Many countries around the globe have recently pursued sustainability. The public and governments are demanding sustainability due to worldwide environmental disasters caused by pollution and man-made activities that impact the ecological system. Green buildings represent a significant component of sustainability, as their construction is intended to reduce natural resources consumption through energy and water conservation. Saudi Arabia is one of the world’s richest countries, but its number of certified green buildings is notably low. In addition, all of these buildings are certified by the US Green Building Council LEED rating system and not by a national organization. It seems that numerous barriers exist, slowing the development and diffusion of green buildings in Saudi Arabia. Through a systematic qualitative research approach, this research aims to explore barriers to the diffusion and adoption of green buildings in Saudi Arabia, which will facilitate the development of green buildings in Saudi Arabia. This research concludes the identification of 14 green building barriers, with lack of skilled personal and unsupportive government policies and regulations being the most significant barriers.</p>

Abstract Green concepts are important things to apply on buildings. The application of the green concept on mixed-use buildings must consider several criteria, one of which is the comfort aspect. The density of commercial buildings in Medan City causes a reduction in green open space, and even many buildings do not comply with the minimum green open space requirements on their buildings, which can support the development of this city to reduce environmental temperatures. The aim of this study is to analyze the green concept that can be applied to mixed-use buildings in urban areas. A mixed-use building design with the application of green building principles is the right choice to reduce the effects of climate. The green building concept can help reduce excess heat radiation inside and outside the building. The method used is qualitative with data collection techniques through observation. The analysis was carried out descriptively to obtain a mixed-use building model with the green building concept. The results show that land use efficiency, energy conservation, materials and water conservation can be applied to provide comfortable on buildings.

Purpose Green roofs are acknowledged as a method to substitute greenery washed out by the urbanization. They provide many ecological and sustainable benefits of greenery; reduce the adverse effects of high-rise building constructions. Though this concept is more popular across many countries over the past few decades, still, implementation of this technology in Sri Lanka is new and scant. Hence, the purpose of this paper is to identify and analyze the potential of green roofs in high-rise buildings in Sri Lanka. Design/methodology/approach The data collection was conducted through expert interviews and questionnaire survey. Expert interviews were carried out to validate the prospects and restraints identified through literature review to the Sri Lankan context and analyzed using content analysis. Questionnaire survey identified the most significant prospects and restraints using descriptive statistics and paired sample t-test. Purposive sampling was used to select participants. Findings Reduction of air pollution, aesthetical appearance, thermal benefits and energy savings, reduction of an urban heat island effect, the addition of points in the green rating system are the top most significant prospects that need to be highlighted in promoting green roof systems in Sri Lankan high rises. Less space allocation on rooftops, lack of technical competence and lack of awareness and research are restraints that need most effective elimination strategies to encourage green roof systems. Originality/value The first identified and quantified prospects and restraints for green roof system in Sri Lankan high-rise buildings can be utilized by the government, donors, multi-lateral agencies to promote the sustainable development in Sri Lanka and this knowledge could be used in different scale awareness programs. The value of this paper is such that the paper discusses the links of green roofs with the other facets of sustainability. The new legal reforms and amendments in Sri Lanka could potentially be pending with findings of this study.
