Приводится анализ энергетической эффективности семейного дома. Сравниваются пять вариантов дома – стандартные, низкоэнергетический и пассивный – с точки...

Scientists from all over the world recognize that energy saving in households is currently very relevant topic. Energy resources are very important factor for each country's economic vitality. Not only the country's replenishment in energy resources is important, but also the reduction of energy...

Increasing energy efficiency and exploiting energy saving potential are two important practices that can help to ensure future energy security in China. This paper proposes a new total factor energy efficiency indicator, based on the directional meta-frontier data envelopment analysis (DEA)...

We present Turkey’s manufacturing-sector innovation data and, for the first time, analyze likely relationships among GDP growth, sectoral innovation intensities, energy consumptions, and energy-saving potentials. We detect a power-law-like relationship between the projected energy-saving...

A set of models are employed to estimate the potential of total energy saved of productions and segmented energy saving for telecom operators in China. During the estimation, the total energy saving is divided into that by technology and management, which are derived from technical reform and...

Effective and efficient ventilation is essential when improving energy performance and Indoor Air Quality (IAQ) of buildings. Reducing air permeability can considerably improve the energy performance of buildings; however, making the buildings more airtight may result in lower rates of natural...

Numerous studies have been conducted to explore the potential usage of natural ventilation in buildings. However, this issue has not yet been effectively resolved due to the inconsistency of air flow patterns and the extent of the parameters involved in the studies. This paper aims to identify...

A 2D unsteady computational fluid dynamics (CFD) model is employed to simulate buoyancy-driven turbulent ventilation in attics with different pitch values and ceiling insulation levels under summer conditions. The impacts of roof pitch and ceiling insulation on the cooling load of gable-roof...
