Energy Issue

Purpose – This study aims at capturing the perspectives of construction professionals into a classified taxonomy of the various characteristics of smart buildings and at developing an index able to define their level of smartness. Design/methodology/approach – A questionnaire survey has been administrated to construction professionals in the service of designers, constructors and owners. Results have been analyzed with the Kruskal–Wallis test and they have been used to develop a smartness index. Findings – Designers and owners are more focused on the energy issue than constructors. The energy captures the attention of practitioners with less years of experience, confirming that the awareness of the energy topic is rather recent. Originality/value – The main characteristics of smart buildings have been structured in domains and subdomains. Their importance has been rated by construction professional and a smartness index for smart building has been developed to provide with a convenient tool for evaluation and benchmarking.

Second Order Phase Transition

We present the analytic Lifshitz solutions for a scalar field model minimally coupled with the abelian gauge field in N-dimensions. We also consider the presence of cosmological constant Λ. The Lifshitz parameter z appearing in the solution plays the role of the Lorentz breaking parameter of the model. We investigate the thermodynamical properties of the solutions and discuss the energy issue. Furthermore, we study the hairy black hole solutions in which the abelian gauge field breaks the symmetry near to the horizon. In the holographic picture, it is equivalent to a second-order phase transition. Explicitly we show that there exists a critical temperature which is a function of the Lifshitz parameter z. The system below the critical temperature becomes superconductor, but the critical exponent of the model remains the same of the usual holographic superconductors without the higher-order gravitational corrections, in agreement with Ginzburg–Landau theories.

Construction industry is one of the sectors that would highly benefit from Nanomaterials with new functionalities and enhanced performances. The use of Nanomaterials in this industry should be considered not only for enhancing material properties and functions but also in the context of energy saving. This paper, aims to keep special attention on low energy buildings which utilizes the key resources of energy or construction materials in a more efficient way than the conventional buildings. Using Nanomaterials in these cases include harvest solar or other forms of renewable energy and energy conservation. The paper presents also applications of more efficient and cheaper solar energy collectors with high flexibility, heat absorbing windows, energy coatings and Nanoinsulations. The flexible insulation allowed the panels to be thin enough to fit within the existing window casements without need to modify window and roof fixtures. The NanoHouse represents a successful method of explaining what Nanomaterials are and how they work.

Total Oil

The transportation sector is the second largest final energy consumer after the industry sector. The main energy issue in the transportation sector in Indonesia is the dominant use of oil fuels. Moreover, almost 60% of total oil fuels are being subsidized. On the contrary, the development and application of New and Renwable Energy (NRE) in the transportation sector has not been very successful. This paper applies the Analytical Hirarchy Process (AHP) in conjuction with optimization of the energy system using MARKAL model to select the best strategy for increasing the role of New and Renewable Energy (NRE) in the transportation sector. Three case studies are applied to evaluate the intervention by policy as an effort to increase the role of NRE in the transportation sector.
