Book excerpt: Excerpt from Performance of Hot-Water Panel Heating Systems in High-Rise Apartments of the Chicago Housing Authority The Chicago Housing Authority constructs and operates a large number of high-rise apartment buildings for low-income families in metropolitan Chicago. Extensive use has been made of hot water panel heating systems in these apartment buildings with the heat being distributed from central heating plants. Records of fuel consumption over a period of three years indicate that some of the lower values of annual fuel consumption per room have occurred in buildings with this type of heating system.

Available in PDF, EPUB and Kindle. Book excerpt: Heating water is typically the second largest use of energy in residential and commercial buildings (after space heating and cooling). Despite its resource intensity, the hot water delivery system is seldom an area of significant focus when constructing a building. As a result, many buildings today are built with poor performing, inefficient hot water delivery systems that take minutes to deliver hot water to the point of use and waste large amounts of energy and water in the process. How quickly and efficiently a hot water system can deliver to the point of use require focus on three areas:• Generation: Heaters shall be sized for meeting both the daily requirements and for the hourly peak loads of the occupants of the building. Hot water can temporarily run out if the design is inadequate and will have higher energy costs if the system is oversized. • Distribution: Once heated, the hot water must be delivered to the intended point of use. The factors influencing the distribution efficiency include length of piping between the water heater and a given fixture, continuous recirculation controls, and materials and insulation effectiveness. • Use: Hot water is used by a variety of fixtures and appliances (faucets, showerheads, clothes washers, and dishwashers). Using efficient products such labeled faucets and showerheads that function at lower flow rates will increase the efficiency of the system.This quick book provides a brief overview of and potential design considerations for hot water plumbing systems for residential and commercial buildings.Learning ObjectiveBy completing this module, the reader will be able to:• Estimate the hot water demands based on theory of probability, fixture types and number of occupants;• Understand the hot water generation techniques, type of fuels and heaters;• Explain three primary factors influencing the heater selection: 1) capacity and frequency of use, 2) heater performance and 3) operating costs;• Determine the appropriate sizing of storage water heaters and compare the use of terms - first heat recovery, storage capacity and recovery rate;• Explain the components of centralized hot water system, direct and indirect heating systems;• Explain the basics of hot water distribution in domestic and commercial installations and its relation to water and energy efficiency;• Understand the application of various types of water supply configurations - an upfeed system, a downfeed system, or some combination thereof;• Understand the difference between the direct and reverse return piping configurations;• Compare and contrast the different control options for designing a continuous recirculation hot distribution system and the impact of such choices on water and energy sustainability;• Size the hot water circulator and the piping diameters on velocity and pressure drop criteria;• Understand the different techniques and options for hot water mixing control;• Learn the facts, formulas and good engineering practices pertaining to energy efficiency and safety.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over recent years, heat pump water heaters (HPWHs) have become more readily available and more widely adopted in the marketplace. For a 6-month period, the Building America team Consortium for Advanced Residential Buildings monitored the performance of a GE Geospring HPWH in Windermere, Florida. The study found that the HPWH performed 144% more efficiently than a traditional electric resistancewater heater, saving approximately 64% on water heating annually. The monitoring showed that the domestic hot water draw was a primary factor affecting the system's operating efficiency.

Available in PDF, EPUB and Kindle. Book excerpt: Apartment temperature data have been collected from the archives of companies that provide energy management systems (EMS) to multifamily buildings in the Northeast U.S. The data have been analyzed from more than 100 apartments in eighteen buildings where EMS systems were already installed to quantify the degree of overheating. This research attempts to answer the question, 'What is the magnitude of apartment overheating in multifamily buildings with central hot water or steam heat?' This report provides valuable information to researchers, utility program managers and building owners interested in controlling heating energy waste and improving resident comfort. Apartment temperature data were analyzed for deviation from a 70 degrees F desired setpoint and for variation by heating system type, apartment floor level and ambient conditions. The data shows that overheating is significant in these multifamily buildings with both hot water and steam heating systems.

Book excerpt: Although heat pump water heaters (HPWHs) have gained significant attention in recent years as a high efficiency electric water heating solution for single family homes, central HPWHs for commercial or multi-family applications are not as well documented in terms of measured performance and cost effectiveness. To evaluate this technology, the Alliance for Residential Building Innovation team monitored the performance of a 10.5 ton central HPWH installed on a student apartment building at the West Village Zero Net Energy Community in Davis, California. Monitoring data collected over a 16-month period were then used to validate a TRNSYS simulation model. The TRNSYS model was then used to project performance in different climates using local electric rates. Results of the study indicate that after some initial commissioning issues, the HPWH operated reliably with an annual average efficiency of 2.12 (Coefficient of Performance). The observed efficiency was lower than the unit's rated efficiency, primarily due to the fact that the system rarely operated under steady-state conditions. Changes in the system configuration, storage tank sizing, and control settings would likely improve the observed field efficiency. Modeling results suggest significant energy savings relative to electric storage water heating systems (typical annual efficiencies around 0.90) providing for typical simple paybacks of six to ten years without any incentives. The economics versus gas water heating are currently much more challenging given the current low natural gas prices in much of the country. Increased market size for this technology would benefit cost effectiveness and spur greater technology innovation.
