Comparing the Energy Requirements of Hot Water Circulation System Control Strategies | Gary Klein, Affiliated International Management, LLC
Circulation systems for service water heating are installed in buildings where the distance from the water heater to the plumbing fixtures and appliances is large and there is a desire to reduce the waste of water and time waiting for the hot water to arrive. Most of these systems have a circulation pump to move the water around the loop. Assuming the same floor plan and location of the circulation loop relative to the plumbing fixtures and appliances, once the loop is full of heated water, the waste of water and time will be the same, regardless of the controls for the loop. The energy required to ensure that hot water is in the supply portion of the loop depends on how the controls change the run time of the circulation pump.
The strategies that are being compared include no circulation, continuous circulation, timer controlled, temperature controlled, time and temperature controlled, demand initiated, and controls that are able to learn the hot water use patterns. The loop is being monitored with recording data loggers that monitor the flow rate and temperature drop through the loop. The electrical energy for the pump is also being monitored and will be reported.
Emerging Opportunities for Heat Metering | James Critchfield, Director, Clean Energy Initiatives, U.S. Environmental Protection Agency
The accurate accounting of thermal energy plays an important role in project finance, state compliance and incentive markets and in the cash flows between project developers and off-takers. The United States currently lacks consensus standards on heat metering, which has the potential to limit policy support for heating and cooling technologies. The presentation will provide examples on where lack of standardization is hindering market development and describe a collaborative pathway forward for industry to develop heat-metering
Emerging Residential Scale Prevention Technologies | Pauli Undesser, WQA Director of Regulatory and Technical Affairs
The world of water treatment technologies is ever changing. Some technologies have made huge improvements in a matter of just a few years, while other technologies are being used for new applications. For example, several technologies that have previously been applied in a controlled environment such as commercial or industrial settings are now migrating into the demanding and highly variable water quality of the residential market.
Further driving water treatment innovations are the pressures applied from environmental impacts such as water scarcity and climate change. These environmental factors are leading water quality swings ranging from moderate to drastic across the US and abroad. To add insult to injury, the water quality changes often impact total dissolved solids, salinity, and even hardness, which can directly impact energy consumption through scale buildup. Even though water heating has fallen from second to third for energy consumption in the US in recent years, it still accounts for almost 20% of energy used making it an area of consumption to watch closely. These environmental factors press water treatment technology innovation to help mitigate the issues. In recent years, several scale prevention technologies have entered the residential market. This presentation will provide a description of the most common scale prevention technologies, how they work, and the test protocols that are under development for product validation of these technologies.
Water Quality Issues in Plumbing Systems with Advanced Water Conservation Features | Dr. M Inayathulla, Department of Civil Engineering, UVCE, Bangalore University and Abdul Matheen, Director, Mechanical, IAPMO India
New buildings increasingly incorporate advanced water conservation features and use of grey water and recycled water for non-potable purposes. Recent experiences highlight the negative impact of these sustainable practices on water quality at the tap. Water residence time in building plumbing can increase markedly, causing microbial growth, taste and odor problems, and elevated lead. In our experience, at some locations as much as 40 minutes of continuous flushing were needed before chloramine levels in the water main were observed at building taps.
WaterSense Flushes Out Concerns With High‐Efficiency Commercial Plumbing | Stephanie Tanner, Lead Engineer, U.S. Environmental Protection Agency’s WaterSense and Robert Pickering, Environmental Engineer, Eastern Research Group Inc.
The EPA estimates that if existing flushometer‐valve toilets flushing at 1.6 gallons per flush (gpf) or greater were replaced with high‐efficiency models, 56 billion gallons of water could be saved annually; therefore, WaterSense is planning to develop a specification to label commercial flushometer‐valve toilets that use 1.28 gpf or less.
This presentation will outline the potential criteria and requirements that WaterSense is considering for its specification to ensure sustained water savings and advanced performance of flushometer‐valve toilets. For instance, WaterSense wants to capitalize on improvements to flushometer‐valve toilet technology, which have the potential to reduce water use by at least 20 percent over the current federal standard of 1.6 gpf.
In addition, the presentation will detail the issues that WaterSense still needs to resolve to ensure flushometer valve toilets can withstand the loads of the commercial restroom and sustain their water savings over the long term. Some of these topics include: aftermarket adjustability of flushometer valves; parts interchangeability that may affect flush volume; testing media used in performance testing; and testing protocol for ensuring superior performance.
Lastly, WaterSense will discuss potential areas of additional research such as how combinations of flushometer valves and toilet fixtures will perform under more stringent performance requirements. Participants in this discussion will learn more about key issues involved in developing performance criteria for high‐efficiency flushometer‐valve toilets and help bring WaterSense one step closer to assisting commercial facilities with water‐efficient fixtures that ensure plumbing system performance.
Moving to continuous water supply in urban India: Implications for Last Mile infrastructure | Kyle Konda - UNC Water Institute
Ensuring plumbing safety is an important public function, and usually involves government adoption and enforcement of a plumbing code. As with any such code, the degree to which safety is maintained depends not only on the content of the code but more importantly on enforcement and compliance. In the United States, the responsibility for plumbing regulation falls to state governments, who delegate this responsibility to local governments to various extents. Using data collected from coding of relevant state statutes and codes, a typology of state plumbing regulation types is created. Using data collected from a national sample of local governments, wide variation in the degree to which plumbing codes are actually enforced, the strategies employed by code officials, and perceived compliance levels are found.
Bio-aerosols in Building Drainage and Plumbing Systems: Cross Contamination, Monitoring and Prevention | Dr. Michael Gormley, Institute for Building and Urban Design, The School of the Built Environment, Heriot-Watt University, Scotland
The building drainage system is not only a means of conveying waste away from a building as safely and as efficiently as possible, it is one of the main ways in which we maintain good public health. Fixture trap seals provide much of this protection, however they are vulnerable to phenomena such as evaporation and air pressure fluctuations, and can be compromised to the extent where no seal exists. The consequences can be severe, as evidenced by the link between infection spread and defective trap seals during the 2002/2003 SARS outbreak in South East Asia.
While defective water traps provide potential routes for infection spread, innovative sonar-like techniques allow the seal of an entire system to be monitored in seconds. This technique, developed at Heriot-Watt University, was validated in a number of ‘live’ buildings, including a complex hospital building. This technique is now well understood – the potential for cross contamination due to pathogen-laden bio-aerosols is less so. Current research using drainage flows from water dosed with Escherichia coli and Pseudomonas spp. - tracks the transmission of pathogens on naturally occurring and mechanically induced air currents, under defective water seal conditions. Previous relevant research investigated Norovirus in hospital building drainage using DNA techniques (RT-PCR) and is reported here also. Taken together, this research represents the cutting-edge of public health engineering, combining innovative engineering solutions with microbiology and fluid mechanics to more fully understand potential hazards to human health in our built environment.
Solid Transport in Near Horizontal Drain Lines: Mechanisms and Modeling Under Low Water Usage Criteria | Dr. Michael Gormley, Institute for Building and Urban Design, The School of the Built Environment, Heriot-Watt
The goals of water conservation and the reduction in carbon emissions due to water and wastewater processing are commendable ones. In unfavorable economic conditions the costs associated with providing potable water are not insignificant and requires minimization for domestic and commercial consumers alike. The provision of good clean water and effective sanitation systems is central to the societal need for good public health.
While these goals are noble, the drive towards reducing the water volume used by one of the largest water consuming fixtures, the WC, provides particular challenges which, should at least be evaluated in a methodical engineering and scientific manner. The move towards ultra-low flush volumes raises concerns that drains may become clogged due to insufficient water availability to maintain self-cleansing velocities.
The modeling of discrete solids in near horizontal drains provides a method by which these challenges can be evaluated in a holistic way. A numerical model has the capability of simulating flows in pipes of different diameter set to different gradients and can also simulate a range of solid types and variables.
This paper compares numerical techniques to physical models over many years of research and shows the significance of flush volume and solid specific gravity in determining the maximum travel distance possible. An evaluation of solid transport hydrodynamics also reveals that as the gradient reduces a change in mechanism occurs, which, counter-intuitively, may assist in extending the maximum travel distance and counteract the more negative effects of reducing water flows as a whole.
Innovative Technologies in Commercial Foodservice | Don Fisher, President/CEO of Fisher-Nickel, Inc.
Green is the buzz in foodservice. And if energy efficiency had a color, it would be green—it saves the environment and it saves cash! Not surprisingly, the motivating force for sustainability in the restaurant business is the potential energy and water savings. A restaurant is a utility hog—per square foot, foodservice consumes more energy and water than any other commercial operation. Fortunately, energy efficiency translates to increased performance—the less energy wasted the more energy available for cooking food product.
Don Fisher will present a medley of innovative technologies that are emerging within the restaurant and commercial foodservice sector. Featured technologies will include optimized kitchen exhaust hoods and demand controlled ventilation, high performance cooking equipment and burner design, and waste heat recovery strategies. Innovative equipment that reduce both water and energy use in the commercial kitchen such as a new generation of ultra-low-flow pre-rinse spay valves and Energy Star dish machines will be highlighted. In conclusion, the responsiveness of codes and standards will be key to transforming this building sector.
Indian Green Building Council (IGBC) and the Challenges in India with Water Conservation | Dr Prem C Jain, Chairman, IGBC & Chairman AECOM India
Indian Green Building Council (IGBC) and the Challenges in India with Water Conservation Indian Green Building Council (IGBC) of the Confederation of Indian Industry (CII) is spearheading the Green Building Movement in India. The Council, as part of its initiatives has launched 8 indigenously developed green building rating systems to suit various types of buildings in India. All the rating systems of IGBC have become national by choice and global in performance. IGBC Rating Systems pro-actively encourage measures that optimize water conservation and bring down excessive dependence on potable water consumption. On an average, IGBC certified green building conserves water to the tune of 30-40 % of normal consumption. The intent of Water Efficiency module in IGBC Green Building Rating System includes:
*Reduce, Recycle, Reuse of water *Limit or eliminate the use of potable water for landscape irrigation
*Limit or eliminate the use of potable water for air-conditioning make-up
*Maximize water efficiency within buildings to reduce the burden on municipal water supply and on capacity of wastewater treatment system
*Use of low flow flush and low flow plumbing fixtures at building level as certified by IAPMO.
*On-site Sewage Treatment Plant for treating the grey & black water and reusing for flushing demand & for landscape use *Capturing free rainwater by storing or recharging the local aquifer within the site.
*Additional Credit points for Green Building certification by IGBC for the above mentioned water conservation measures. Some of the challenges in India for Water Conservation include:
*Very low tariff for municipal water supply
*India depends heavily on bore wells and water tankers, these are the root cause for constantly dropping water table; every drop of raw water needs to be captured & stored.
*Availability of affordable STP’s for residential sector
*Awareness amongst public about the low flow plumbing fixtures & other water related products and technologies
*Need for more technology providers
*Monitoring & management of sewage and water treatment plants
*Capacity building of workforce to create awareness for urgent need of water conservation. IGBC with the support of all stakeholders is making concerted efforts in addressing and overcoming these challenges.
