Strengthening Taiwan’s Green Building Certification System from Aspects of Productivity and Energy Costs to Provide a Healthier Workplace

This study estimates the relationship between poor indoor environmental quality (IEQ) and the increasing labor costs in green buildings in Taiwan. Specifically, poor performance of IEQ including HVAC, lighting, and indoor air quality, influences the health and well-being of occupants and leads to worse productivity, ultimately causing increased personnel cost. In Taiwan’s green building certification (GBC) system, the energy-savings category is mandatory while the IEQ category is only optional. It means that certified building cases may not reach the expected level in IEQ. Thus, this study reviews the thermal environment, indoor air quality (IAQ), and illumination performances of IEQ-certified and non-IEQ-certified buildings in 20 green buildings. Building energy and IEQ simulations were conducted to analyze the relationships between indoor comfort, energy cost, and personnel cost in green buildings. The results show that IEQ-certified green buildings averagely perform better than non-IEQ-certified ones in the aspects of IEQ and building costs. Besides, 3 of 13 non-IEQ-certified green buildings undertake extremely high additional expenditure for the poor IEQ. The results correspond to some previous findings that green-certified buildings do not necessarily guarantee good building performance. This study further inspects the pros and cons of Taiwan’s GBC system and proposes recommendations against its insufficient IEQ evaluation category. As the trade-off of energy-saving benefits with health and well-being in green buildings has always been a concern, this study aims to stimulate more quantitative research and promote a more comprehensive green building certification system in Taiwan.

Effect of Fibrillated Cellulose on Lime Pastes and Mortars

The use of nanocellulose in traditional lime-based mortars is a promising solution for green buildings in the frame of limiting the CO2 emissions resulting from Portland Cement production. The influence of the fibrillated cellulose (FC) on lime pastes and lime-based mortars was studied incorporating FC at dosages of 0%, 0.1%, 0.2% and 0.3wt% by weight of binder. The lime pastes were subjected to thermal and nitrogen gas sorption analyses to understand if FC affects the formation of hydraulic compounds and the mesoporosities volume and distribution. The setting and early hydration of the mortars were studied with isothermal calorimetry. The mechanical performances were investigated with compressive and three-point-bending tests. Furthermore, fragments resulting from the mechanical tests were microscopically studied to understand the reinforcement mechanism of the fibres. It was found that 0.3wt% of FC enhances the flexural and compressive strengths respectively by 57% and 44% while the crack propagation after the material failure is not affected.

The Impact of 3D Coordinate Technology Using Nanomaterials on Architecture Engineering Industry

Coordinate technologies play an important role in many industrial applications, especially for eco nanobuildings and spaces. Lately, the global new architecture seems to be more automated as appeared in the parametric architecture, topological, animate, metamorphic, and isomorphic and per formative architecture. They all depend on the visualization, the high precision techniques, and the 4th dimension all within sustainability. But till now, there is no main environmental space code, unit or standards to deal with to insure that the environmental design became in a form of an easier one to be the design of the era as all the global calls aware us to preserve the nature from pollution. Mainly within the call for the nanotechnology, if there is found a least architectural volumetric unit which can fulfill all the environmental sustainable systems within the visionary and the 4th dimensional acts, then we can act with the environment with easier spaces that can be duplicated in a uniform way, to work easily for measure and estimate the budget of his supposed built space. Therefore, the main liable issue concerns the research for the least architectural volumetric unit, and we can call it the nanoarchitectural unit. As nanoarchitecture is a virtual and proposed kind of architecture, which the architects aim to create it or follow it the nanotechnology to insure that the 3D technology is to submit as an application in all branches of science, to achieve a dream of the present-day from sustainability and environment for future generations. Accordingly, recent studies have confirmed that 3D coordinate technology using digital printing has an important subtle impact on industry, especially for green buildings and spaces.

Transferring Biophilic and Universal Design Theory to Practice With Learning From Green Buildings

The study aims to guide the assisted living facility (ALF) design, in which biophilic design, which is observed to have positive physiological, psychological, and sociological effects on humans, is observed, and the principle of universal design is accessible and designed for everyone. Since there is no place called a biophilic ALF, the study is supported by a nature-oriented design method called Green Building Rating Tools. Green building certificate systems are explored in terms of biophilic and universal design, and three of the certifications show credits linked to the theories researched. With these certificates, green building certified ALFs located in the same region are selected. With the methodology applied on the case studies of three ALFs that received these certificates, how and where biophilic and universal design patterns can be transferred from theory to practice has been examined. The study observed the extent of 14 biophilic design patterns in ALFs and tabulated how to find each pattern in these facilities according to the methods and places.

Life cycle energy analysis of a green building in Vietnam

The paper presents the life cycle energy analysis (LCEA) of an office green building in Hanoi, Vietnam to prove the advantages of green buildings regarding energy efficiency and environmental effects. The case study building is a concrete structured one, which consists of 3 basements, 17 floors, and 1 attic with a gross area of 14,112 m2. In the study, the building’s embodied energy is determined based on the contained energy coefficient of the ith material and its quantity needed. Whereas, the operating energy is computed according to the annual energy consumption of the building, which is stimulated by the EnergyPlus simulation software. Relying on the relative share of the demolition energy with the life cycle energy that has been proposed by previous publications, this category will be estimated. Results showed that the initial embodied energy contributed the largest share to the life cycle energy (61.37%), followed by operational energy (27.61%). It also indicated that the percentage share of the operational energy of a green building is much lower than that of other buildings. The primary reason for this is associated with the usage of environmentally friendly materials and energy-saving equipment in the design option of the green building. Therefore, it can be convincing evidence that may help to change the mindset of decision-makers in Vietnam about green buildings.

Analisis Biaya Pemeliharaan Bangunan Gedung Dengan Konsep Green building Dan Bangunan Gedung Dengan Konsep Non Green building

Based on the calculation, the maintenance costs of green building and non-green building still conform the standards of the Minister of Public Works Regulation and the standard of the Minister of Finance Regulation.

Evaluation Algorithm of Ecological Energy-Saving Effect of Green Buildings Based on Gray Correlation Degree

The environmental protection attribute and energy-saving level of green buildings cannot be described by the traditional evaluation model. In order to solve the above problems, a new ecological energy-saving effect evaluation algorithm of green buildings based on gray correlation degree is designed. Based on the framework of building energy-saving index system, the environmental protection evaluation standards are divided and the results are used to screen the energy-saving indexes, so as to complete the establishment of green building ecological energy-saving index system and standards. Then, the evaluation set is established, and the evaluation scale of each layer of indicators is accurately located according to the weight value of each index. On this basis, the membership matrix is constructed. By calculating the index weight and determining the fuzzy synthesis operator, the rating process of the algorithm is improved and the analysis of the evaluation algorithm of environmental protection and energy conservation indicators of green building materials based on gray correlation degree is realized. The experimental results show that the designed algorithm has good stability of the fitting curve, can save energy, and has low cost.
