This book was released on 2004 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy used in residential buildings is a major energy use in Canada (21% of all energy) and presumably in most areas in the Northern hemisphere. A substantial fraction of this energy (24%) is used in multi-residential buildings. However, very little attention has been given to examining the patterns of energy and water consumption, let alone how they can be improved. This report suggests that significant savings and improvements in the efficiency of multi-residential systems are achievable, and this could go a long way toward reducing energy usage and fulfilling Canadian Kyoto obligations. Watershed Technologies Inc. and OZZ Energy Solutions Inc. have been monitoring energy and water usage in multi-residential buildings in the Toronto area since 1996. The present analysis looks at detailed (hourly) gas and electricity loads in 34 buildings and water consumption in 21 buildings over a two-year period from May 2001 to April 2003. An earlier report by OZZ documented the different physical features of these buildings and presented an overall summary and a preliminary analysis of gas, electricity and water consumption data along with daily and seasonal summaries. A more detailed analysis is offered in the present report. A new model is developed which describes the building's energy consumption for cooling and heating more effectively than the traditional degree-day model. The new model quantifies not only the changes in energy load per unit change in temperature but also its effective thermal capacity, the heating system overhead and system response to other weather factors, namely wind, relative humidity and solar access. More than two fold differences in the energy per unit area or water used per apartment unit among the buildings are observed. A study of seasonal and daily variability suggests that at least a part of these differences in the building energy efficiency can be attributed to poor or complete lack of energy management in many of the buildings. The data also suggests that in-suite electric heating is 2.5 times more efficient than central gas heating systems in multi-residential buildings. The same appears true of in-suite air conditioning, when compared to centralized cooling systems.

Housing Technology Group and published by CMHC. This book was released on 2005 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research project was undertaken to review detailed energy and water consumption monitoring data which has been collected for 34 multi-unit residential buildings. The project used the data to determine annual energy and water consumption as well as hourly, weekly and monthly energy and water use patterns. Concurrent natural gas and electricity consumption is also detailed. An analysis was undertaken to determine if there was any correlation between the characteristics of the buildings and energy or water use patterns observed. The research revealed that significant variations exist in the normalized energy and water use from building to building and that patterns in the variations were difficult to predict based on building characteristics and occupancy type.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States is embarking on an ambitious transition to a 100% clean energy economy by 2050, which will require improving the flexibility of electric grids. One way to achieve grid flexibility is to shed or shift demand to align with changing grid needs. To facilitate this, it is critical to understand how and when energy is used. High- quality end-use load profiles (EULPs) provide this information, and can help cities, states, and utilities understand the time-sensitive value of energy efficiency, demand response, and distributed energy resources. Publicly available EULPs have traditionally had limited application because of age and incomplete geographic representation (Frick, Eckman, and Goldman 2017; Frick 2019). To help fill this gap, the U.S. Department of Energy (DOE) funded a three-year project - End-Use Load Profiles for the U.S. Building Stock - that culminated in the release of a publicly available dataset1 of simulated EULPs representing residential and commercial buildings across the contiguous United States. The motivation for this work is further detailed in a November 2019 report: Market Needs, Use Cases, and Data Gaps (Mims Frick et al. 2019). This Methodology and Results report provides detailed descriptions of how the dataset was developed, intended for an audience of dataset and model users interested in the technical details. These details include descriptions of all of the model improvements made for calibration and the final comparisons to empirical data sources. A companion report, End-Use Load Profiles for the U.S. Building Stock: Applications and Opportunities, will be published subsequently and will describe example applications and considerations for using the dataset, intended for an audience of general dataset users.

The project team, made up of researchers from the National Renewable Energy Laboratory (NREL), Lawrence Berkeley National Laboratory (LBNL), and Argonne National Laboratory, ultimately will use calibrated physics-based building energy models to create these EULPs.
Download or read book Energy and Water Efficiency in Multi Unit Residential Buildings written by Canada Mortgage and Housing Corporation. Policy and Research Division and published by Canada Mortgage and Housing Corporation. This book was released on 2002-01-01 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Implementing energy and water efficiency is a crucial consideration for today's property managers and building owners. Energy and water costs in multi-residential buildings can account for anywhere from 25% to 50% of total operating costs. While amendments to building codes and standards over the past 20 years have improved energy and water performance in newer buildings, over 50% of housing was constructed prior to 1980. Few of those have been upgraded to today's standards of energy efficiency. Improving energy and water efficiency can decrease operating costs, reduce maintenance fees, lower tenant turnover rates, increase the asset value of property, and extend the life of the building. CMHC, in partnership with the Ontario Ministry of Municipal Affairs and Housing (OMMAH), has developed a manual that details energy and water efficiency measures for existing multi-unit residential buildings. The document is based on a manual originally developed by the Ontario Ministry of Housing in the early 1980's. The new manual offers proven, current energy efficiency measures for the building envelope, mechanical, electrical, and domestic hot water heating systems. Both the User Guide and Technical Manual are designed to assist property managers in implementing an energy and water conservation program in mid- and high-rise residential buildings. They can be used to help organize activities, develop detailed energy and water conservation plans, and provide an understanding of which energy and water efficiency measures are best. The User Guide provides advice on how to manage activities, from conducting an energy/water preliminary assessment, determining appropriate conservation measures, estimating payback and the development of an energy/water plan. The Technical Manual outlines in detail more than 60 energy and water conservation measures for multi-unit buildings. Each provides basic details on assessing the viability of measures in relation to the specific requirements of buildings, as well as recommendations on integrating measures into ongoing maintenance, repair and/or renovation/retrofit work. Each measure can be used in isolation, in selected groupings, or integrated into any maintenance, repair and/or renovation/retrofit work on the building. Note: Individual energy and water efficiency measures have been placed on the CMHC high-rise website as the energy and water efficiency "Tip of the Week". The manual will form a part of the reference material for a series of energy management seminars being organized by the Ontario Non-Profit Housing Association in the spring of 2004.

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.

Available in PDF, EPUB and Kindle. Book excerpt: To track progress toward aggressive multi-year whole-house energy savings goals of 40-70% and onsite power production of up to 30%, the U.S. Department of Energy (DOE) Residential Buildings Program and the National Renewable Energy Laboratory (NREL) developed the Building America Research Benchmark in 2003. The Benchmark is generally consistent with mid-1990s standard practice, as reflected in the Home Energy Rating System (HERS) Technical Guidelines, with additional definitions that allow the analyst to evaluate all residential end-uses, an extension of the traditional HERS rating approach that focuses on space conditioning and hot water. A series of user profiles, intended to represent the behavior of a''standard'' set of occupants, was created for use in conjunction with the Benchmark. Finally, a set of tools was developed by NREL and other Building America partners to help analysts compare whole-house energy use for a Prototype house to the Benchmark in a fair and consistent manner.
