Download or read book Measured Home Performance written by Lew Harriman and published by . This book was released on 2011-11-01 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report to the California Energy Commission's Public Interest Energy Research Program (PIER) helps Home Performance Contractors train their crews to achieve superior results in home energy retrofits. The book was updated and expanded in December of 2012 to include the impressive measured results from 15 home energy retrofits in Redding, California that were accomplished using the principles and practices outlined in this report. Homeowners may also find this information useful, when they want to understand the techniques that regularly achieve utility bill savings of 40 to 70% on an annual basis. This approach-called Measured Home Performance-is different from other means of saving energy. Most importantly, all of the home's energy features are redesigned and improved at the same time, so the synergies take effect immediately. Next, measurements are taken all the way through the process, to ensure that both the redesign and the installation are excellent. Improved comfort and energy savings are assured by high-tech field measurements, taken by the craftspeople themselves rather than by 3rd-party auditors. This process provides real-time feedback to the real decision makers-the technicians who do the work. Measurements of critical parameters like duct air leakage, while-house air leakage, supply air flow at each grill, CO concentration & draft pressure of combustion appliances and superheat and subcooling of the AC equipment make the installation quality-good or poor-are instantly clear to the crews. They can fix any shortcomings on the spot, rather than waiting days or weeks for 3rd-party testing results. Craftspeople measuring key parameters as they work transforms the workplace. Measured quality not only ensures successful results for the homeowners, it self-trains crew members in the field, where they learn more quickly than in the classroom. At the end of every day, workers know when they have achieved excellent results-a powerful motivator that works to everybody's benefit.

Download or read book Energy Efficiency in Domestic Appliances and Lighting written by Paolo Bertoldi and published by Springer. This book was released on 2023-05-20 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains peer-reviewed papers presented at the 10th International Conference on Energy Efficiency in Domestic Appliances and Lighting (EEDAL'19), held in Jinan, China from 6-8 November 2019. Energy efficiency helps to mitigate CO2 emissions and at the same time increases the security of energy supply. Energy efficiency is recognized as the cleanest, quickest and cheapest energy source. Not only this, but energy efficiency brings several additional benefits for society and end-users, such as lower energy costs, reduced local pollution, better outdoor and indoor air quality, etc. However, in some sectors, such as the residential sector, barriers to investments in energy efficiency remain. Legislation adopted in several jurisdictions (EU, Japan, USA, China, India, Australia, Brazil, etc.) helps in removing barriers and fosters investments in energy efficiency. These initiatives complement innovative financing schemes for energy efficiency, the provision of energy services by energy service companies and different types of information programs. At the same time, progress in appliance technologies and in solid state lighting offer high levels of efficiency. LED lighting is an example. As with previous conferences in this series, EEDAL’19 provided a unique forum to discuss and debate the latest developments in energy and environmental impact of households, including appliances, lighting, heating and cooling equipment, electronics, smart meters, consumer behavior, and policies and programs. EEDAL addressed non-technical issues such as consumer behavior, energy access in developing countries, and demand response.

Download or read book Management of Legionella in Water Systems written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2020-02-20 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.

Download or read book NREL Tests Integrated Heat Pump Water Heater Performance in Different Climates Fact Sheet written by and published by . This book was released on 2012 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical highlight describes NREL tests to capture information about heat pump performance across a wide range of ambient conditions for five heat pump water heaters (HPWH). These water heaters have the potential to significantly reduce water heater energy use relative to traditional electric resistance water heaters. These tests have provided detailed performance data for these appliances, which have been used to evaluate the cost of saved energy as a function of climate. The performance of HPWHs is dependent on ambient air temperature and humidity and the logic controlling the heat pump and the backup resistance heaters. The laboratory tests were designed to measure each unit's performance across a range of air conditions and determine the specific logic controlling the two heat sources, which has a large effect on the comfort of the users and the energy efficiency of the system. Unlike other types of water heaters, HPWHs are both influenced by and have an effect on their surroundings. Since these effects are complex and different for virtually every house and climate region, creating an accurate HPWH model from the data gathered during the laboratory tests was a main goal of the project. Using the results from NREL's laboratory tests, such as the Coefficient of Performance (COP) curves for different air conditions as shown in Figure 1, an existing HPWH model is being modified to produce more accurate whole-house simulations. This will allow the interactions between the HPWH and the home's heating and cooling system to be evaluated in detail, for any climate region. Once these modeling capabilities are in place, a realistic cost-benefit analysis can be performed for a HPWH installation anywhere in the country. An accurate HPWH model will help to quantify the savings associated with installing a HPWH in the place of a standard electric water heater. In most locations, HPWHs are not yet a cost-effective alternative to natural gas water heaters. The detailed system performance maps that were developed by this testing program will be used to: (1) Target regions of the country that would benefit most from this technology; (2) Identify improvements in current systems to maximize homeowner cost savings; and (3) Explore opportunities for development of advanced hot water heating systems.
Download or read book Building America Case Study Simple Retrofit High Efficiency Natural Gas Water Heater Field Test Minneapolis Minnesota written by and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: High performance water heaters are typically more time consuming and costly to install in retrofit applications, making high performance water heaters difficult to justify economically. However, recent advancements in high performance water heaters have targeted the retrofit market, simplifying installations and reducing costs. Four high efficiency natural gas water heaters designed specifically for retrofit applications were installed in single-family homes along with detailed monitoring systems to characterize their savings potential, their installed efficiencies, and their ability to meet household demands. The water heaters tested for this project were designed to improve the cost-effectiveness and increase market penetration of high efficiency water heaters in the residential retrofit market. The retrofit high efficiency water heaters achieved their goal of reducing costs, maintaining savings potential and installed efficiency of other high efficiency water heaters, and meeting the necessary capacity in order to improve cost-effectiveness. However, the improvements were not sufficient to achieve simple paybacks of less than ten years for the incremental cost compared to a minimum efficiency heater. Significant changes would be necessary to reduce the simple payback to six years or less. Annual energy savings in the range of $200 would also reduce paybacks to less than six years. These energy savings would require either significantly higher fuel costs (greater than $1.50 per therm) or very high usage (around 120 gallons per day). For current incremental costs, the water heater efficiency would need to be similar to that of a heat pump water heater to deliver a six year payback.
