Building Energy Efficiency Fundamentals of Building Energy Dynamics by Bruce D. Hunn, Fundamentals of Building Energy Dynamics assesses how and why buildings use energy, and how energy use and peak demand can be reduced. It provides a basis for integrating energy efficiency and solar approaches in ways that will allow building owners and designers to balance the need to minimize initial costs, operating costs, and life-cycle costs with the need to maintain reliable building operations and enhance environmental quality both inside and outside the building. Chapters trace the development of building energy systems and analyze the demand side of solar applications as a means for determining what portion of a building's energy requirements can potentially be met by solar energy. The approach taken is a commonsensical one, starting with the proposition that the purpose of buildings is to house human activities, so that conservation measures that negatively affect such activities are based on false economies. The goal is to determine rational strategies for designing new buildings and retrofitting existing buildings to bring them up to modern standards of energy use. The energy flows examined are both large scale (heating systems) and small scale (choices among appliances.).
Retrofitting for Energy Conservation by William Clark, Convert residences and light-commercial buildings from energy-wasters to energy-efficiency. New remodelling codes require improvements in energy efficiency. Home and building owners want to reduce their energy costs. And now with Retrofitting for Energy Conservation, construction and design professionals can discover the most up-to-date plans, methods, tools, and materials for improving energy conservation in existing structures. Almost 85% of energy-conserving projects are retrofits, according to the National Association of Homebuilders. Retrofitting for Energy Conservation gives you the tools you need to meet this demand with step-by-step help in retrofitting any residence or light commercial building for energy savings. From assessing the challenge and offering the client options through initial project design and final execution of the building plan, this book gives you solutions that meet and exceed code requirements.
Energy efficiency - In physics and engineering, including mechanical and electrical engineering, energy efficiency is a dimensionless number, with a value between 0 and 1. The energy efficiency of a process is defined as: Seasonal energy efficiency ratio - Seasonal Energy Efficiency Ratio (SEER) is a measurement of efficiency for cooling devices such as heat pumps and air conditioners. A unit's SEER is calculated by dividing the total number of BTUs of heat removed from the air by the total amount of energy required by the unit. Passive solar - Passive solar design is a broad category of solar power techniques and strategies for regulating a building's indoor air and domestic water temperatures, using climate, site features, architectural elements, and landscape materials. The goal is typically to increase the comfort, efficiency and reliability of a building, while reducing its operating costs and dependence on other sources of energy for heating and cooling. EU energy label - According to an EU Directive most white goods and light bulb packaging must have an EU Energy Label clearly displayed when offered for sale or rent. The energy efficiency of the appliance is rated in terms of a set of energy efficiency classes from A to G on the label, A being the most energy efficient, G the least efficient. buildingenergyefficiency |
