Abstract Urban building energy modelling has an essential role in the estimation of demand at urban or neighbourhood scales. However, current methods have limitations reproducing realistic gross usage. Although it is theoretically possible to simulate all components heating system detail, such extensive approach significantly increases computational effort, prohibiting a large scale probabilist...

We present a mixed finite element formulation for flexoelectric nanostructures that is coupled with topology optimization to maximize their intrinsic material performance with regards to their energy conversion potential. Using Barium Titanate (BTO) as the model flexoelectric material, we demonstrate the significant enhancement in energy conversion that can be obtained using topology optimizati...

with the increasing world population and limitations on arable land, increasing the yield per unit is one of alternatives human food supply. greenhouse cultivation as one ways of increase the performance can arrive this purpose. but the energy restriction of another human challenges, so that increase the performance without considering energy consumption almost appears to be meaningless. due to...

The objectives of the research are to examine the energy utilization profile of the wood manufacturing industry with respect to system level production parameters and investigate the viability of specific energy efficiency measures. The Industrial Assessment Center (IAC) has conducted energy assessments in the wood manufacturing industrial sector in the State for several years. The energy utili...

to increase agricultural crops’ quality and to minimize losses in the final product and used energy during the drying process, major drying system parameters should be continuously controlled. precise control of such parameters is attained by using automatic control systems. to optimize the overall dryer efficiency in a forced convective solar dryer, a controller was designed, constructed a...

This study seeks to provide insights on understanding the contemporary problems of energy efficiency in Ukrainian universities by developing a comprehensive energy efficiency management framework that encompasses its participating subjects, objects and key drivers along with suggesting its implementation mechanism and tools. Emphasis should be given that the current situation of inefficient and...

In 2013, the United States used more than 25% of its energy supply for the purpose of moving people and goods from one place to another, i.e., in the transportation sector. 1 Even modest improvements that reduce transportation energy consumption can reduce energy imports and greenhouse gas emissions, two of ARPA-E’s primary goals. To date, technologies directed at transportation have focused pr...

the share of dc-based renewable energy resources (rers) and electricity storage systems are increasing due to developments of smart grid technologies. moreover, the share of dc-based load has rapid growth due to significant developments of power electronic technologies. therefore, a more flexible power system is required for efficient integration of emerging loads and generators. in this paper,...
