Book excerpt: Several energy-saving design changes in residential space-heating systems were examined to determine their energy-conservation potential and cost effectiveness. Changes in conventional and advanced systems (such as the gas heat pump) were considered. The energy and cost estimates were developed from current literature, conversations with heating and equipment manufacturers and dealers, and discussions with individuals doing research and testing on residential space-heating equipment. Energy savings as large as 26, 20, 57% were estimated for design changes in conventional gas, oil, and electric space-heating systems, respectively. These changes increased capital cost of the three systems by 27, 16, and 26%, respectively. For advanced gas and electric systems, energy savings up to 45 and 67%, respectively, were calculated. The design changes needed to produce these energy savings increased capital costs 80 and 35%. The energy use and cost relationships developed for the space heating systems were used as input to the ORNL residential energy-use simulation model to evaluate the effect of space-heating improvements on national energy use to the year 2000. Results indicated a large reduction in national energy use if improved conventional and advanced systems were made available to consumers and if consumers minimized life-cycle costs when purchasing these systems.

This book was released on 2017-03-04 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: District heating and cooling (DHC) combined with renewable energy sources can help meet rising urban energy needs, improve efficiency, reduce emissions and improve local air quality. Although currently dominated by fossil fuels such as coal and gas, DHC systems can be upgraded, or new networks created, to use solid biofuel, solar and geothermal energy technologies. Depending on local conditions, renewable-based DHC brings a range of benefits, including increased energy security, improved health and reduced climate impact.To date, only a few countries have taken advantage of their renewable resource potential for DHC or created policies to promote further uptake. Sweden and Switzerland have started promoting renewable-based district heating,while Denmark - with ambitious decarbonisation policies -already uses high shares. Many cities and regions envisage a growing role for district in their energy plans; some are also looking increasingly at district cooling.As this REmap sector study from the International Renewable Energy Agency (IRENA) shows, renewables could feasibly supply more than one fifth of the energy needed for DHC worldwide. But to drive the transition, policy makers need to fully understand the costs, bene¿ts and actual potential for renewable-based DHC.

This book was released on 2005 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residential homes throughout the state of Iowa were used in a comprehensive study to evaluate performance, efficiency, and economics of existing vertical and horizontal GCHP systems. The objective of this study was to compare vertically-configured and horizontally-configured ground-coupled heat pumps without radiant floor heating. All homes were constructed between 1997 through 2001 and are of typical construction. The homes studied are distributed throughout the state of Iowa. It was also desired to compare heat pumps to natural gas furnaces for economics. The energy analysis predicted how much energy was required to condition the homes studied, and then estimated the coefficient of performance of each heat pump. Energy audits were performed on each home to determine physical characteristics necessary for the analysis. The utility bills for each home and actual weather data was acquired for analysis of the homes. Through the energy analysis of the heat pumps, the average (heating) coefficient of performance between vertical and horizontal configurations differed by less than 10%. Thus, it was determined that vertically and horizontal configurations of ground-coupled heat pumps operate at approximately the same efficiency. The economic analysis determined the cost to heat a home using a heat pump and a natural gas furnace. Two different electrical rates were used for the heat pumps, and one rate for the natural gas furnace. The economic analysis of winter operating cost showed significant savings of operating a ground-coupled heat pump over a natural gas furnace.

Download or read book Energy and Cost Analysis of Residential Water Heaters written by Robert A. Hoskins and published by . This book was released on 1977 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: A detailed computer model is developed to calculate energy flows for residential electric and gas water heaters. Model equations are derived from applications of the first law of thermodynamics, analysis of manufacturers' literature, and related studies. The model is used to evaluate the energy (and associated initial cost) impacts of alternative designs to reduce water heater fuel use. Model results show that the largest heat loss in an electric water heater is conduction through jacket walls (14% of energy input). An additional 5% is lost through the distribution pipe for a 7.6 m (25 ft) long pipe. The remaining 81% of energy input is used to heat water. In a gas water heater, conduction losses through jacket and distribution pipe are 12% and 3%, respectively; and 33% is lost up the flue (due to main burner and pilot light operation). Only 52% of energy input to a gas water heater is used to heat water. Several energy-saving design changes are examined using the energy model. Changes for both electric and gas water heaters are: increase jacket insulation thickness, reduce jacket insulation thermal conductivity, reduce thermostat setting, and add insulation to the distribution line. Application of all these changes to an electric water heater would reduce electricity use 17% and increase initial cost 27%. Additional changes examined for gas water heaters are: reduce pilot rate, eliminate pilot and add electric ignitor and flue closure, and reduce excess air for combustion by increasing flue baffling. Implementing all these changes to a gas water heater (except addition of electric ignitor) would reduce gas use 27% and increase initial cost 26%. These results show that there are large opportunities for reducing water heater energy use with only small initial cost increases.
