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...

Street lighting has a big impact on the energy consumption of Spanish municipalities. To decrease this consumption, the Spanish government has developed two different regulations to improve energy savings and efficiency, and consequently, reduce greenhouse-effect gas emissions. However, after...

The rapid growth of transport requirements in China will incur increasing transport energy demands and associated environmental pressures. In this paper, we employ a generalized data envelopment analysis (DEA) to evaluate the relative energy efficiency of rail, road, aviation and water transport...

This paper discusses the history, status quo, and future prospects of Zero Emission Buildings (ZEBs) in the Republic of Korea. The advantages of, and requirements for ZEBs are described, concerning the factors of energy, water, nutrients, and biomass. ZEBs are characterized by net zero energy...

This paper extends prior research on energy inefficiency in China by utilizing a unique shadow price framework allocation in 30 Chinese provinces. We estimate the shadow price for energy input using the framework of production, and use the ratio of the shadow price to the market price to...

This study explores the impact of oil depletion on the energetic efficiency of oil extraction and refining in California. These changes are measured using energy return ratios (such as the energy return on investment, or EROI). I construct a time-varying first-order process model of energy...

Traditionally, the Finnish legislation have focused on energy use and especially on energy used for heating space in buildings. However, in many cases this does not lead to the optimal concept in respect to minimizing green house gases. This paper studies how CO₂ emission levels are affected by...

This paper captures the breadth of complexity in the debate about ‘green jobs’ as the world seeks to transition to a ‘low carbon economy’ and to reduce greenhouse gas emissions through the reduction of reliance for energy on the burning of fossil fuels. A consideration is provided within...

The promotion of sustainable development is the European affirmation in the international arena and is European policy for the Union. However, the current situation—where the Sustainability is more intention than a practice—risks such European affirmation. In our analysis, we have assumed...

We study the energy-efficient power allocation techniques for OFDM-based cognitive radio (CR) networks, where a CR transmitter is communicating with CR receivers on a channel borrowed from licensed primary users (PUs). Due to non-orthogonality of the transmitted signals in the adjacent bands,...
