Download or read book The Need for Improved Airtightness in Buildings written by Handegord, G. O. (Gustav O.) and published by National Research Council, Division of Building Research. This book was released on 1979 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infiltration and exfiltration of air through the building envelope has come to be accepted as an intrinsic feature of a building; in residential construction some regard it as necessary for the proper ventilation and operation of the house. In contrast to these attitudes, it is suggested that air leakage wastes heat and is detrimental to the performance of a building. Air leaking into a building cannot be treated or conditioned nor can its rate of supply or distribution to the occupied space be controlled. Attempts to do so by intentional pressurization of the building results in greater waste of energy and promotes increased condensation and thus deterioration of the building fabric. Air leakage through a building envelope, and between building compartments, can also disrupt the intended operation of heating, ventilating and air-conditioning systems and places limitations on the control of noise, fire and smoke.
Download or read book Deep Energy Retrofit written by Alexander Zhivov and published by Springer Nature. This book was released on 2020-07-13 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides detailed information on how to set up Deep Energy Retrofits (DERs) in public buildings, and shares in-depth insights into the current status of the major technologies, strategies and best practice examples of how to cost-effectively combine them. Case studies from the U.S.A. and Europe show that that Deep Energy Retrofit can be achieved with a limited core technologies bundle readily available on the market. Characteristics of some of these core technology measures depend on the technologies available on an individual nation’s market, on the minimum requirements of national standards, and on economics (as determined by a life cycle cost analysis). Also, requirements to building envelope-related technologies (e.g., insulation levels, windows, vapor and water barriers, and requirements for building airtightness) depend on specific climate conditions. This Guide provides best practice examples of how to apply these technologies in different construction situations. High levels of energy use reduction using core technology bundles along with improvements in indoor climate and thermal comfort can be only achieved when a Deep Energy Retrofit adopts a quality assurance process. In addition to design, construction, commissioning, and post-occupancy phases of the quality assurance process, the Guide emphasizes the importance of clearly and concisely formulating and documenting the Owner’s goals, expectations, and requirements for the renovated building during development of the statement of work. Another important component of the quality assurance process is a procurement phase, during which bidders’ qualifications, their understanding of the scope of work and its requirements, and their previous experience are analyzed. The building sector holds the potential for tremendous improvements in terms of energy efficiency and reducing carbon emissions, and energy retrofits to the existing building stock represent a significant opportunity in the transition to a low-carbon future. Moreover, investing in highly efficient building materials and systems can replace long-term energy imports, contribute to cost cutting, and create a wealth of new jobs. Yet, while the technologies needed in order to improve energy efficiency are readily available, significant progress has not yet been made, and “best practices” for implementing building technologies and renewable energy sources are still relegated to small “niche” applications. Offering essential information on Deep Energy Retrofits, the book offers a valuable asset for architects, public authorities, project developers, and engineers alike.

Download or read book Climate Change the Indoor Environment and Health written by Institute of Medicine and published by National Academies Press. This book was released on 2011-10-01 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The indoor environment affects occupants' health and comfort. Poor environmental conditions and indoor contaminants are estimated to cost the U.S. economy tens of billions of dollars a year in exacerbation of illnesses like asthma, allergic symptoms, and subsequent lost productivity. Climate change has the potential to affect the indoor environment because conditions inside buildings are influenced by conditions outside them. Climate Change, the Indoor Environment, and Health addresses the impacts that climate change may have on the indoor environment and the resulting health effects. It finds that steps taken to mitigate climate change may cause or exacerbate harmful indoor environmental conditions. The book discusses the role the Environmental Protection Agency (EPA) should take in informing the public, health professionals, and those in the building industry about potential risks and what can be done to address them. The study also recommends that building codes account for climate change projections; that federal agencies join to develop or refine protocols and testing standards for evaluating emissions from materials, furnishings, and appliances used in buildings; and that building weatherization efforts include consideration of health effects. Climate Change, the Indoor Environment, and Health is written primarily for the EPA and other federal agencies, organizations, and researchers with interests in public health; the environment; building design, construction, and operation; and climate issues.

This book was released on 2021-06-18 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal comfort and indoor air quality (IAQ) issues have gained significant interest in the scientific and technical community involved in building performance analysis and other related subjects. In terms of thermal comfort, the achievement and maintenance of a thermally acceptable indoor environment is affected by energy costs, and energy poverty is a widespread problem globally. There is a call for energy-efficient architecture for a developed and sustainable world. However, with the use of renewable energy that increased considerably in recent years, new technical challenges arose for the energy sector. Consumers are key players in this context, as flexibility in demand is crucial to cope with the intermittent nature of most renewable energy sources. Active demand-side participation is particularly important to ensure the efficient use of locally and globally available energy. Sustainability, human comfort, and healthy living environments have become top priorities. Advancements in Sustainable Architecture and Energy Efficiency explores how housing is a key health factor for individuals and looks at factors such as air quality, ventilation, hygrothermal comfort, lighting, physical environment, building efficiency, and other areas as important pieces in healthy architecture. It discusses how the poor application of these parameters can directly affect human health and how sustainable architecture provides a solution. Beyond just labeling the important facets of architecture for healthy living, this book will look at different perspectives of energy consumption and demand to ensure sustainable energy, increased energy efficiency, improved energy policies, and reasonable energy costs for homes. This book is ideal for architects, designers, engineers, energy engineers, environmental scientists, practitioners, researchers, academicians, and students interested in architecture that is both conducive to healthy living and energy efficiency.
Download or read book Detrimental Effects of Air Leakage on Building Enclosure Performance Energy Consumption Occupant Comfort and Moisture Accumulation written by Jason S. Der Ananian and published by . This book was released on 2018 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and construction industry is increasingly interested in the effects of air leakage and how it relates to mechanical system efficiency, thermal comfort issues for building occupants, condensation, moisture accumulation, and concealed deterioration of building materials within wall and roof assemblies. Recent changes to the international building codes and ASHRAE Standard 90.1, Energy Standard for Building Except Low-Rise Residential Buildings , recognize and limit uncontrolled whole-building air leakage rates. This paper includes three case studies that highlight the importance of limiting uncontrolled air leakage through building enclosures by demonstrating the detrimental effects of air leakage as well as the benefits of improving airtightness in the same buildings. The first two case studies, which include a historic school building and a contemporary natatorium, showed that significant reductions in air leakage rates improved occupant comfort and eliminated condensation and moisture accumulation within wall and roof assemblies, respectively. The third case study, an existing 86,400-square-foot office building with an upgraded building enclosure, illustrated the impact of varying building enclosure air leakage rates on energy consumption using a calibrated whole-building energy model simulation. This energy model incorporated measured whole-building air leakage rates and was calibrated using one year of site-specific weather and submetered energy consumption of electric and mechanical systems.
Download or read book Pretty Good House written by Michael Maines and published by Taunton Press. This book was released on 2022-05-24 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pretty Good House provides a framework and set of guidelines for building or renovating a high-performance home that focus on its inhabitants and the environment--but keeps in mind that few people have pockets deep enough to achieve a "perfect" solution. The essential idea is for homeowners to work within their financial and practical constraints both to meet their own needs and do as much for the planet as possible. A Pretty Good House is: * A house that's as small as possible * Simple and durable, but also well designed * Insulated and air-sealed * Above all, it is affordable, healthy, responsible, and resilient.

Download or read book Ventilation and Airflow in Buildings written by Claude-Alain Roulet and published by Routledge. This book was released on 2012-05-16 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy efficiency in buildings requires, among other things, that ventilation be appropriately dimensioned: too much ventilation wastes energy, and insufficient ventilation leads to poor indoor air quality and low comfort. Studies have shown that ventilation systems seldom function according to their commissioned design. They have also shown that airflow measurement results are essential in improving a ventilation system. This key handbook explains why ventilation in buildings should be measured and describes how to measure it, giving applied examples for each measurement method. The book will help building physicists and ventilation engineers to properly commission ventilation systems and appropriately diagnose ventilation problems throughout the life of a building. Drawing on over 20 years of experience and the results of recent international research projects, this is the definitive guide to diagnosing airflow patterns within buildings.

Download or read book Cost C16 Improving the Quality of Existing Urban Building Envelopes written by Ebbe Melgaard and published by IOS Press. This book was released on 2007 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of changes in the composition of the population, society changes continuously with respect to various factors including age-structure, family composition and the availability of energy. Changes lead to situations that are reflected in the commissioning of buildings, which is gradually shifted from new construction to the reuse and renovation of existing buildings. The adaptation of buildings often requires the modification of facades and the construction behind. The scope of this action within the COST Transport and Urban Development Domain is to improve techniques and methods for envelopes of buildings constructed during the last half of the 20th century in the COST countries. In other words it is directed on the building envelopes of the so-called non-traditional buildings. This publication is based on a support by COST, an intergovernmental European framework for international cooperation between nationally funded research activities. COST creates scientific networks and enables scientists to collaborate in a wide spectrum of activities in research and technology.
