“…Therefore, investments in new energy infrastructures and grid improvements must be achieved [3,5] and governments are increasingly interested in creating laws to improve this management [6]. Photovoltaics (PV), as well as other renewable energies, provide safe and clean electricity and, can play an important role in the solution of the aforementioned problems.…”

“…The rapid increase of the electricity demand is a general constant around the world. This growth responds to various reasons, among which stand out the increasing awareness of global warming caused by greenhouse emissions, the inevitable exhaustion of traditional energy sources in the following decades (fossil fuels) and the need for countries to assure energy self-dependence [1][2][3].…”

Solar Decathlon Europe (SDE) is an international multidisciplinary competition in which 20 university teams build and operate energy-efficient solar-powered houses. The aim of SDE is not only scientific but also educational and divulgative, making visitors to understand the problems presented by real engineering applications and architecture. From a research perspective, the energy data gathered during the competition constitutes a very promising information for the analysis and understanding of the photovoltaic systems, grid structures, energy balances and energy efficiency of the set of houses. This article focuses on the electrical energy components of SDE competition, the energy performance of the houses and the strategies and behaviors followed by the teams. The rules evaluate the houses' electrical energy self-sufficiency by looking at the electricity autonomy in terms of aggregated electrical energy balance; the temporary generation-consumption profile pattern correlation; and the use of electricity per measurable area. Although the houses are evaluated under the same climatological and consumption conditions, production results are very different due to the specific engineering solutions (different electrical topologies, presence or absence of batteries, diverse photovoltaic module solutions, etc.).

“…The amount of energy consumed in a building might vary depending on the building envelopes and the building fabric ( Piette et al , 1995 ;Kamal, 1997 ). But, most importantly, it depends on how the HVAC equipment and lighting systems are operated and controlled ( Levine et al , 1995 ).…”

This research investigates and analyses the use of energy-effi cient lighting design in an exclusive spa project in the southwest of England. The originality of this work is the area of investigation, which is in an exclusive spa. Before this study, hardly any investigation has been done in this kind of building, as many previous studies focused on energy-effi cient lighting in offi ce buildings. The main area of this investigation includes the study and analysis of the good practice of energy-effi cient lighting. The method used in this case study is to some extent similar to ethnographic research because the researcher was heavily involved in the energy-effi ciency lighting design as a lead building services design engineer from stage B to stage K of the Royal Institute of British Architects (RIBA) plan of work. The major fi ndings in this case study are that the energy-effi cient lighting design could still be achieved without sacrifi cing the visual comfort and aesthetic requirement of the building, which are a critical feature of an exclusive spa. Energy-effi cient lighting could be implemented if it is considered right from the early design stage.

Zigzag pore based molecular simulation on the separation of CO₂/CH₄ mixture by carbon membrane

et al. 2018

A zigzag-type pore structure was proposed for the separation of a CO 2 /CH 4 binary mixture by carbon molecular sieve membrane (CMSM). A defect-free pore and three kinds of defect pores, i.e., random, uniform, and partial defect, were considered to improve the separation performance. Adsorption and diffusion behaviours of pure gases and a gas mixture were simulated by the grand canonical Monte Carlo (GCMC) method and non-equilibrium molecular dynamics (NEMD) method, respectively. The pressure ranged from 10-100 kPa and the temperature was between 273-348 K during simulation. The calculated isotherms of CO 2 and CH 4 showed an acceptable agreement with the experimental data for the defect-free pores of 0.67 nm in size at 298 K. Examination on the effect of pore sizes showed that 0.67 nm was the appropriate option for separation. The total selectivity was 20.1 at 298 K and 100 kPa with the pore size of 0.67 nm, which is consistent with the experimental value. The adsorption was determined as the dominant separation mechanism between adsorption and diffusion. Compared with the defect-free pores, the introduction to the random and uniform defect pores can improve the total selectivities and the random defect provided superior separation performance. An appropriately low temperature and small pore size were beneficial to the separation.
