Download or read book Actual Energy Consumption in Dwellings written by Olivia Guerra Santin and published by IOS Press. This book was released on 2010 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residential buildings have continuously improved in energy efficiency, partly as a consequence of the introduction of energy regulations in many countries. Although better thermal properties and systems efficiency have lowered energy consumption for space heating in recent decades, substantial differences in energy consumption in similar dwellings are still being observed. These differences in consumption are thought to be caused by differences in occupancy patterns, by quality of construction and by rebound effects.This research addresses the effect of energy performance regulations and occupant behaviour on energy consumption for space and water heating in dwellings built after the introduction of the energy performance regulations in the Netherlands. The results of this research show that improving the energy efficiency of buildings alone is not enough to decrease that energy consumption.

Download or read book Energy and Thermal Time Constant in Buildings written by Joseph Nowarski and published by Joseph Nowarski. This book was released on 2016-05-02 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design of building's exterior walls has important influence on energy consumption, building cost and thermal comfort. It influences also heating and cooling devices size. Optimization of energy consumption of the building requires consideration of the building materials, their thickness and mass, type and thickness of insulation, and location of the insulation layer. The correct way to optimize all the above parameters is calculation of temperatures and energy consumption in dynamic process, which means considering changes every few seconds. This may be done only with computer program. It is not easy to gain expertise on such programs. In addition, submission of input values to the program is time consuming and frustrating process, which in many times ends with errors. This work analyses if the Thermal Time Constant method may be applied to determine energy quality of the building as an alternative to the dynamic simulation program. The Thermal Time Constant method is much easier, simpler and faster than computer dynamic simulation program. Few examples of exterior wall design were selected to calculate the energy consumption and room temperatures. Two locations were selected for the calculations, one with moderate summer and the second with moderate winter. The dedicated dynamic simulation computer program was applied to gain data regarding the energy consumption, maximum and average room temperatures for south facing room and for north facing room at each location. Thermal Time Constant reflects the thermal inertia and thermal mass of the building. Higher Thermal Time Constant (TTC) moderates the difference between day and night in the room, flattening the room temperatures extremes caused by ambient temperature and solar energy. Higher TTC is not necessary more expensive. To take advantage of high TTC is not so the question of additional investment, but the question of understanding the TTC concept. In some cases consideration of TTC caused changes to the building's design and construction technique, bringing benefits to the contractor, to the tenants and to the national economy. Disregarding TTC leads to wrong decisions, wrong design, waste of money for building's construction and increased energy consumption.

Download or read book Real Prospects for Energy Efficiency in the United States written by National Research Council and published by National Academies Press. This book was released on 2010-06-10 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: America's economy and lifestyles have been shaped by the low prices and availability of energy. In the last decade, however, the prices of oil, natural gas, and coal have increased dramatically, leaving consumers and the industrial and service sectors looking for ways to reduce energy use. To achieve greater energy efficiency, we need technology, more informed consumers and producers, and investments in more energy-efficient industrial processes, businesses, residences, and transportation. As part of the America's Energy Future project, Real Prospects for Energy Efficiency in the United States examines the potential for reducing energy demand through improving efficiency by using existing technologies, technologies developed but not yet utilized widely, and prospective technologies. The book evaluates technologies based on their estimated times to initial commercial deployment, and provides an analysis of costs, barriers, and research needs. This quantitative characterization of technologies will guide policy makers toward planning the future of energy use in America. This book will also have much to offer to industry leaders, investors, environmentalists, and others looking for a practical diagnosis of energy efficiency possibilities.

Download or read book Cost Optimal and Nearly Zero Energy Buildings nZEB written by Jarek Kurnitski and published by Springer Science & Business Media. This book was released on 2013-11-20 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cost optimal and nearly zero energy performance levels are principles initiated by the European Union’s (EU) Energy Performance of Buildings Directive which was recast in 2010. These will be major drivers in the construction sector in the next few years, because all new buildings in the EU from 2021 onwards are expected to be nearly zero energy buildings (nZEB). This book introduces the technical definitions, system boundaries, energy calculation methodology and input data needed to set primary energy based minimum/cost optimal and nZEB requirements in national energy frames. Worked examples are provided to illustrate the calculation of delivered, exported and primary energy, and renewable energy contribution. Five case studies of high performance nZEB office buildings across Europe are reported to show alternative technical solutions and to draw some general design rules based on completed nZEB buildings. Specific features of the nZEB design process, especially in the early stages, and architectural competitions are included. These describe important design issues in the scoping and conceptual design phase, allowing design streams to be controlled so that specified targets can be met. This book is intended for readers who need to be aware of or are working with the energy performance of buildings – for decision makers in public and private sectors, architects, engineers, construction clients, consultants, contractors, manufacturers and students. The editor of this book, Professor Jarek Kurnitski has made major contributions to the preparation of the European REHVA nZEB technical definition and has developed energy calculation frames for current Estonian and Finnish energy performance regulations. He is the leader of nZEB research at Tallinn University of Technology in Estonia and Aalto University in Finland, and he has over 300 publications.
