This seminar discuss the requirements of ASHRAE 90.1 2010 in the areas of building envelope, lighting, power and equipment efficiencies. In addition, topics such as economizer, reheat requirements, fan design limitation calculation and heat recovery requirements are presented.
A chilled water plant design consists of multiple components interconnected by piping to form an efficient way to provide cooling and heating to a large building or facility. This seminar explains a basic water cooled chiller plant design and its components.
A water chiller provides the chilled water pumped to air handling unit coils to ensure occupant comfort, usually by ductwork and air diffusers. Chilled water is much easier and more economical to install when compared to an all-air-system. Each component of a chiller plant design is discussed along with an overall efficient plant control strategy.
Designers often think that determining comfort conditions is as easy as using 75°F and 50% RH. However, if you are doing a LEED analysis the ASHRAE 55 Standard must be used to define comfort conditions. The standard requires looking at six primary factors and the predicted mean vote procedure that determine if comfort conditions will be achieved. In addition it evaluates these conditions at different seasons of the year. This presentation provides guideline on how to comply with the standard and the methods used in a LEED analysis.
This Seminar Series addresses how ASHRAE Standard 189.1 and LEED® will co-exist in the industry. Comparisons are made as to where requirements are the same and where they are different. ASHRAE 189 is anticipated to begin showing up in building codes in the near future and it is imperative that engineers and designers understand how these two important documents interact.
This seminar takes the designer through the pros and cons of single chiller, parallel, series and series counter-flow chiller plant design.
A constant flow system is the simplest chilled water design to operate. Constant speed pumps provide a fixed quantity of water to the system at all times, controlled by 3-way valve control at the air handler coils. At low load building operation, the chilled water flow is by-passed around these coils.
The seminar discusses the benefits and disadvantages of a constant flow design, comparing various chilled water supply temperatures and return chilled water options. The impact of energy use of these options will be demonstrated.
In this seminar we discuss how weather impacts chiller performance and how a system can be designed to optimize plants for cold condenser water operation. We also review how chiller construction can be used to leverage cold condenser water-associated energy savings.
In this seminar we will compare chiller compression and how load and lift is impacted by each. We will review the results of ASHRAE Research Projects 601 and 751, how to evaluate chiller performance and strategies for staging chiller plants to optimize performance.
ASHRAE 90.1 requirements have continued to become more stringent with each revision to the standard. The impact on chiller efficiency has led many to believe that little more can be done to improve efficiency of chillers. This presentation looks at how the selection of the type of chiller and taking advantage of its operating envelope as well as the use of a series counterflow piping arrangement can result in over a 50% improvement over the standard.
Some applications such as hospitals and hospitality have a constant need of heating energy even during the hottest days of the year and these same facilities often need to run chillers during the coldest days. Engineers often question of what chiller technology will most efficiently recover what is otherwise wasted energy. This presentation evaluates how screw and centrifugal chiller technology and best be applied to efficiently recover the rejected energy. The best solution depends on part load performance and chiller piping arrangements.

When properly applied, Waterside Economizer can be a power tool for energy savings in a WSHP system. By utilizing the cold ambient conditions to generate chilled loop temperature, the Waterside Economizer can provide “Free” system cooling. This presentation provides a path to understanding Waterside Economizers for WSHP systems and how to properly apply them for maximum energy savings.
WSHP systems are a widely popular system, due to their flexibility and high efficiency for both cooling and heating. With new advances in technology and design strategies, there are many ways to further enhance WSHP system efficiency. This presentation explores some of those efficiency enhancing concepts, such as waterside economizer, enhanced motor technologies, and utilizing DOAS units.
The piping system used on screw chillers has an impact on their performance. This presentation looks at how the chiller plants hydronic system influences screw chiller operation at part load and why a good turn down ratio is important. Changing condenser water temperatures and varying system load represent a significant opportunity for energy savings but the chiller and the piping system must be designed to take advantage of the saving potential.
In the current economic environment building owners are more than ever faced with optimizing economic value of the building while maintaining occupant comfort and security. New intelligent buildings not only control energy use and maintain comfort but anticipate occupant needs. This presentation looks at the new trends in intelligent buildings. The use of building automation is described in providing customized comfort conditions, energy use dashboards and even elevator systems that optimize use and minimize occupant wait time.
A popular system combination is WSHP units with a centralized DOAS system. This presentation identifies methods to enhance the efficiency of WSHP systems and reviews the various reheat systems available for packaged DOAS units.
ANSI/ASHRAE Standard 62.1 “Ventilation for Acceptable Indoor Air Quality” endeavors to achieve the necessary balance between IAQ and energy consumption by specifying minimum ventilation rates and IAQ that will be acceptable to human occupants. Air Handling Unit design requires that proper selection of air filters is considered to not only to maintain adequate IAQ, but minimize static pressure drop and therefore AHU operations cost. Nationwide, HVAC designers have recently included more outside air to meet IAQ concerns through dilution. Complicating the dilution strategy are ASHRAE 90.1 /189.1 guidelines calling for higher efficiency in building design. Recently, the use of outside air has taken on a more serious element, as designers are asked to protect buildings from potential “extraordinary circumstances” that could come in the form of chemical or biological contaminant released close to a building air intake system. The presentation will focus on the balance that can be achieved between environmental quality, safety and energy efficient design.
Health Care facility air conditioning plays an important role in patient therapy by controlling airborne microorganisms, viruses, and hazardous chemicals that may be present in the indoor environment. The nature of the health care environment requires that special attention at the design stage be considered to limit air movement between departments, dilute or remove air borne contaminants, and recognize that temperature / humidity conditions my vary in areas within the same building.
Health Care HVAC designers must consider the control of airborne infectious disease, room pressure relationships, and Outdoor Air Requirements (ASHRAE Standard 62.1 / 170) to meet Health Care Facility IAQ concerns. Complicating the dilution strategy are ASHRAE Standard 90.1 and 189.1 guidelines calling for higher efficiency in LEED / High Performing Building Design. The presentation will focus on infection sources, control measures, air movement and proper filtration techniques that can be designed into the building’s air handling system. An overview of anti-microbial construction techniques as they apply to dedicated outdoor air systems will also be discussed.
As Dedicated Outdoor Air Systems (DOAS) have gained in popularity, many different supply air control methods have arisen. Every one of these methods has something in common; a reheat system. This presentation explores the various types of DOAS reheat systems available, such as Hot Gas Reheat, Liquid Subcooling, and Sealed Refrigerant Loops; and describes how to apply reheat systems for various supply air control methods, such as neutral supply air, space sensible load offset, and space latent load offset.
This symposium will examine the unique air distribution requirements required in Hospital applications. This will include patient rooms, waiting areas, laboratories and operating rooms. Special design considerations such as minimizing contamination risks, clean room environment and providing proper systems for high ceiling areas will be examined.
In this presentation, we will discuss two different methods of identifying existing building energy savings – Energy Audits and Retro-Commissioning. We will discuss the process for both studies, the similarities and the differences, their applicability to legislation like Local Law 87 and Executive Order 88, and various methods of implementation. We will also identify various incentive programs that are available statewide for the energy study and implementation projects.
In order to meet the increased expectations of building occupants, designers must be aware of the conflicts between first cost economics, occupant productivity and life cycle costs. Buildings that do not meet the needs of the occupants often result in expensive redesign or worse, result in lawsuits against all parties involved. First, we need to understand the rules:
With the goal of saving energy over the 90.1 baseline (Overhead VAV), many architects are challenging the mechanical engineer to come up with alternate systems that will meet this goal. Displacement Ventilation (DV), Underfloor Air Distribution (UFAD) and Chilled Beams all have a potential to save energy, and meet these needs. I will briefly cover pros and cons of all 4 methods of air delivery:
This presentation looks at tools an engineer can use to determine the most cost and energy effective solution to chiller projects. There is no one solution that is the perfect system for all applications. Things like system load, weather conditions and chiller performance make nearly every project unique. In this presentation the steps of evaluating these various influences on energy and economic performance are evaluated by using a step by step evaluation process.
This presentation will focus on the design of Custom DOAS units with respect to providing adequate OA, and considering the IAQ procedure when the reduction of outdoor air pollutants is a concern. A system approach to combining DOAS units with chilled beam technology will be reviewed. Particular focus will be given to this combined strategy’s energy savings potential as it is applied to LEED EA credits
Arriving at the correct ventilation system design for a multiple-zone application using the ASHRAE Standard 62.1-2004 (2007) Ventilation Rate Procedure is not a simple task. There are many variables that must be factored into the process some of which include complex equations. The reader should first have an understanding of all the Ventilation Rate Procedure concepts.
Arriving at the optimized ventilation system design for a multiple-zone application requires further analysis. This may include the ability to utilize load calculation software to evaluate multiple scenarios in order to arrive at the most cost effective quantity of ventilation air while maintaining good indoor air quality for the specific application
Environmental issues have driven changes in the refrigerants used in air conditioning and refrigeration equipment. This presentation will provide a brief historical perspective of refrigerants that have been used in the past, look at refrigerants that were introduced to deal with ozone depletion and finally take a look at refrigerants that are being considered down the road to reduce greenhouse gas emissions. We will also review changes being made to ASHRAE Standards 34 and 15 as well as the codes to deal with the new refrigerants.
This presentation starts with the often forgotten fundamentals of the fan laws and reading fan curves and demonstrates how the best selection might not be the larger size. Forward curve fans have been the popular choice for years but in recent years the use of plenum fans has become more common. This presentation explores where the use of plenum fans best fit and how to apply them to achieve a cost effective and energy efficient solution.

This session looked at the changes to the LEED V4.0 for New Construction Standard as they impact HVAC design. Some strategies which can be used to optimize points between indoor air quality and energy were demonstrated using different building types. The concepts demonstrated can be used to evaluate meeting both IEQ and EA credits for various building types that reflect the impact of local climate.
Energy modeling has grown dramatically in the last ten years and this workshop was designed to enrich the understanding of the Performance Rating Method so one can successfully and efficiently apply energy modeling methods for LEED 2009 Energy ad Atmosphere Credit 1 project.
In January 2010 a new standard for sustainability was released by ASHRAE, Standard 189.1. Like ASHRAE Standard 90.1, this standard will likely be adopted into building codes around the country since it is written in code enforceable language. Since this standard is very similar to the LEED ratings, the question becomes how does this impact LEED®? Will LEED® ratings change or disappear? How are the LEED® requirements and ASHRAE Standard 189 requirements similar and how are they different? This seminar will address how ASHRAE Standard 189.1 and LEED® are likely to be used in the marketplace and where requirements are the same and how they are different. It is anticipated that this standard will begin showing up in building codes in the near future and it is imperative that engineers and designers understand how these two important documents interact. Topics in this workshop include site selection, building envelope construction, water efficiency, energy efficiency, materials impact, and indoor air quality. A basic understanding of the LEED® rating system and ASHRAE 90.1 are assumed for this presentation.
With a decline in new construction and increase in government initiatives to reduce existing building energy use, opportunities in the existing building market have never been better. The LEED EB O&M rating system was presented as a tool specifically for the existing building market. This presentation described the fundamental tools necessary to apply LEED EB O&M as a guide in tracking and measuring sustainability performance.
Chiller application topics such as variable flow primary piping systems, variable speed operation; 15F vs. 10F condenser water rise, and the impacts on chiller selection. Additionally the use of NPLV as a tool for chiller evaluation; and a discussion on the merits of industrial versus commercial grade machine design are covered. Finally a brief discussion on chiller plant size and number and type of chillers that make sense.
Everyone says people are their most important asset and LEED stresses the importance of maintaining the indoor environment, but all too often facility managers focus on energy and ignore comfort. Why? One reason is that they’re not measuring comfort. This presentation describes the importance of comfort in terms of productivity and LEED points and introduces a simple metric for measuring comfort.
Entropy is the natural enemy of efficiency. Even the finest LEED® certified systems will degrade over time, and sometimes we accelerate that degradation by "twiddling" with the controls. This presentation will show how to use simple BAS tools like trending and alarming to spot problems without overwhelming your maintenance team with nuisance alarms.
The federal government has mandated that all states bring their state energy codes up to at least the level of ASHRAE 90.1- 2010 by 2013. The 2010 version is a significant improvement (30%) over the 2004 version which used as the benchmark and incorporated over 109 addenda. One of the largest energy uses in a commercial building is the HVAC system so many of these changes have a direct impact on HVAC designers. This workshop will give the HVAC designer a practical evaluation of the 2010 changes and the way they will influence HVAC design. Several practical examples are used and climate specific impacts are highlighted allowing designers to evaluate the impacts of the changes on their designs.
This workshop will explain the advantages of VRF systems for different applications. It will describe the differences in 2 pipe and 3 pipe systems and explain how ASHRAE 15 requirements can be met with VRF systems. In addition, how oil return is accomplished and the various methods of assuring oil return will be explored.
This seminar explores the application of Induction Beams in a building and how they compare with Chilled Beams. Control methods relating to space temperature and humidity control are examined.
