The recent ban on conventional incandescent lamps for residential use led Brazilian consumers to choose from three main lighting technologies: incandescent halogen, CFL (Compact Fluorescent Lamp), and LED (Light Emitting Diode). Despite the fact that their electrical performances are well known,...

This paper explores the impact of retrofitting single-family residential buildings in historic districts with energy efficiency measures that are compliant with the 2012 version of the International Energy Conservation Code (IECC). This study focuses on Sears's kit homes that were built in the...

Irrigating the front surface of a PV panel is one method for reducing its operating temperature, thus increasing the output power. Several studies have investigated this method. Nevertheless, information on the thermal effects and energy benefits provided by irrigation over several operating...

The rational use of energy and energy-efficient environmental public street lighting is an important topic. In the design of new public lighting installations, national regulations containing energy-efficient guidelines are already used. Nevertheless, either in new installations or in...

Efficient use of energy in agroecosystems will reduce environmental problems, prevent destruction of natural resources and serve to promote sustainable agriculture as an economical production system. The aim of this study was to investigate the energy use efficiency in four double cropping...

This study investigates the effect of the presence of fireplaces at the household level independent of the function of ambiance and indoor air quality. The focus of this study is on the winter heating energy use of homes with and without fireplaces to promote energy conservation. Three years of...

The Brazilian government has been promoting energy efficiency measures for industry since the eighties but with very limited returns, as shown in this paper. The governments of some other countries dedicated much more effort and funds for this area and reached excellent results. The...

This work shows a sensitivity analysis of the economic impact of different energy performances of air-conditioning within the Mexican housing sector. For this purpose, a cooling-load calculator program in function of the indoor temperature is developed. The program also calculates the...

China's iron and steel industry has developed rapidly over the past two decades. The annual crude steel production is nearly half of the global production, and approximately 90% of the steel is produced via BF-BOF route that is energy-intensive. Based on the practice of integrated steelmaking...

Variable refrigerant flow (VRF) systems are known for their high energy performance and thus can improve energy efficiency both in residential and commercial buildings. The energy savings potential of this system has been demonstrated in several studies by comparing the system performance with...
