1565-TRP, Development of the ASHRAE Design Guide for Dedicated Outdoor-Air Systems

State of the Art (Background)The use of dedicated outdoor-air systems for ventilation has become increasingly popular throughout theworld. In developing countries and countries which have only recently made mechanical cooling an

assumption, the problems of inadequate ventilation have become more widespread. Also, in many urbanareas, the outdoor air quality is so poor that simply bringing outdoor air into the HVAC system without special care can reduce rather than increase indoor air quality. Finally, the problems of mold in buildings inall climates are often either catalyzed or caused by inadequate dehumidification of incoming ventilation air.

Unfortunately, many of the dedicated outdoor-air systems designed and installed today to avoid theseproblems are ineffective. Often, they are designed to achieve only one or two of the many functions necessary.They may cool the air efficiently, but fail to dry it; they may dry the air, but fail to filter it or heat it during thewinter months; or they may fail to vary the ventilation airflow in response to building occupancy, whichneglects the pot ential to save energy during most of the buildings operating hours. Others use overly -simplified control strategies, neglect or improperly apply exhaust-air-energy recovery, and/or deliver theconditioned outdoor air to the building in a manner that reduces or limits the benefit of decoupling theventilation from space conditioning.

All of these shortcomings and errors increase installed costs as well as energy use. And they often fail toprovide adequate amounts of ventilation air, or they provide excessive amounts of ventilation air, whichwastes energy and increases carbon emissions. Currently, sources of good design guidance are spread acrossvarious publications and presentations, making it difficult for practicing HVAC design engineers to easilyobtain, understand, and put to productive use. And most importantly, much of the expertise and lessonslearned from designing dedicated outdoor-air systems has not yet been written down, but remainsinaccessible except through personal conversations with grizzled veterans over drinks during ASHRAEmeetings.

Justification and Value to ASHRAEThis design guide will help practicing HVAC engineers design dedicated outdoor-air systems that minimizeenergy use, maximize indoor environmental quality, and balance life-cycle cost with environmental impact.

A forum, titled Dedicated Outdoor -Air Systems: What information is required to develop a uniformdesign guide, was held at the 2007 ASHRAE Summer Meetings in Long Beach, CA. The consensus fromthe attendees was that a design guide would be very helpful, and a list of topics to be included in such aguide was generated during the forum.The first recommendation listed in the workshop report for Improving the Applications Volume of theASHRAE Handbook (http://www.ashrae.org/publications/page/1554 ) is to create a separate, newchapter on dedicated outdoor-air systems. In fact, the participants spent time developing a detailedoutline of the suggested chapter. Publication of a separate design guide would allow for 1) more detailedcoverage of the subject and 2) higher quality graphics, than a handbook chapter would allow.

This new design guide will:Define the step-by-step process for sizing the dedicated outdoor-air unit and local (space) HVACequipment

Compare the various dedicated OA system configurationsDescribe the available types of dedicated OA equipment (direct expansion, chilled water, desiccant, orcombinations of these) and related components (air-to-air heat exchangers, evaporative cooling, etc.)Share best practices to advance the state-of-the-art Counsel engineers how to avoid common design mistakes (pitfalls) that result in re-work or poor systemperformance, and how to overcome barriers to the use of dedicated outdoor-air systems

Since it will be the first compilation of its kind, it will be a very useful tool for practicing HVAC designengineers. This design guide would be a special ASHRAE publication and would be sold by ASHRAE. The TC is

requesting RAC to fund the development of this publication, as it has done for many of the current ASHRAEdesign guides. Examples of similar design guides that have been funded by RAC include: Underfloor AirDistribution Design Guide, Designers Guide for Ce iling-Based Air Diffusion, Laboratory Design Guide, DesignGuide for Tall Commercial Buildings, Application Guide: Chiller Heat Recovery, Design Guide for CombustionTurbine Inlet Air Cooling Systems, Practical Guide to Noise and Vibration Control for HVAC Systems, andApplication of Manufacturers Sound Data.

Following completion of this guide, the TC will request funding from the ASHRAE Learning Institute (ALI) tocreate a new short course or online training course based on the content of this guide.

ObjectiveThe job of the successful Principal Investigator (PI) will be to research the hard-won expertise about dedicated outdoor-air systems by reviewing the list of papers, articles, and seminar presentations providedby the PMS (partial list included in this work statement) and interviewing DOAS experts (both inside andoutside of the ASHRAE community) to understand the practical aspects of designing, installing and operatinga DOAS from both technical and economic perspectives. Then the PI will assemble, write, edit, and illustrate afour-color book which communicates this expertise effectively to a working- level HVAC designer who has toget the job done by Friday.

After the book has been completed, approved by the PMS, and is press-ready, the PI will examine the content

from the perspective of the needs of a brief chapter (less than 16 pages) on the same subject, to be included inthe ASHRAE Handbook HVAC Systems and Equipment. The contractor will provide text and graphics whichwill assist the cognizant technical committees in their job of assembling, editing, and illustrating that newchapter. The text and graphics shall be provided by the contractor in the format required for the printedversion of the ASHRAE Handbook, so that neither the technical committees nor ASHRAE staff must allocatetime to re-draw or provide additional supporting illustrations, photos, diagrams, or tables.

To be clear, this project does not require laboratory work or field research in the traditional sense. Instead, it requires a much more complex set of tasks. The successful Principal Investigator must research the current practical and economic aspects of system design, installation, and operation. A successful result will demand acombination of research, writing, design, illustration, and pre-press production skills. Using these skills, the PIwill take the results of research into practical experience and deliver it in a form that allows HVAC designersand owners to apply the information to commonly-built commercial and institutional buildings as opposed

to research prototype buildings or technology demonstration projects.

ScopeThe following work is to be performed by a single contractor, with subcontractors used as required toprovide subject matter expertise and other services. In general, this design guide is to be developed as apractical "how to" manual (not a theoretical treatise) that provides evaluation techniques, designmethodology, and design examples. It should not address technologies that are not practical, proven, or welldocumented. The design guide will summarize information with many examples, photographs, tables, graphs,and high-quality figures and diagrams. Models for the standard of writing and graphic presentation of thisbook are provided in the Other Information to Bidders section of this work statement.

Task 1: Development and Approval of the Detailed Table of Contents, Layout, and Graphics Standards Using the detailed outline and list of existing papers, articles, and seminar presentations included in this work

statement, along with extended research into user needs and interviews with experts, the principalinvestigator (PI) will develop a detailed table of contents for the design guide, addressing all of the topicsraised in the outline, plus any other topics which the PI has learned, through user and expert interviews, willadvance the goal of a practical design guide for everyday HVAC designers.

The draft table of contents (TOC) will be submitted to the Project Monitoring Subcommittee (PMS) for review,modification, and approval within 90 days of the contract award. The PI shall provide a written version of thedraft TOC at least two (2) weeks before a teleconference with the PMS members, in which the PI shall present the proposed TOC and describe the logic behind both its structure and content, based on his/her researchinto user needs.

At the same time or earlier, the PI shall provide and explain the proposed layout and graphic styles which willbe used to create the design guide. Representative master pages for all major sections shall be provided inAdobe inDesign format. These shall include paragraphs and illustrations which show the proposed type faces,line weights, and other graphic styles required to present the content in both draft and final press-ready form.Both the PMS and ASHRAE Special Publications staff shall approve these formats to ensure that the guide will,after approval, proceed smoothly through the print production process.

Note also that this design guide shall be prepared using dual units; e.g., rational inch-pound with equivalent SIunits shown parenthetically. SI usage shall be in accordance with IEEE/ASTM Standard SI-10. Graphicstandards for the layout, text, graphics and tables must accommodate dual units.

Task 2: Development of the Draft GuideUsing the detailed table of contents approved by the PMS, along with the graphic styles approved by the PMSand ASHRAE staff, the Principal Investigator will provide drafts of each chapter of the guide, complete withdraft graphics, tables, and diagrams in-place and in color. The completed drafts will be submitted to the PMSfor review as they are completed, allowing the PMS a minimum of two (2) weeks of review time per chapter.Within that time frame, the PMS will submit suggested changes, additions, or deletions to the PI forincorporation into the draft.

Task 3: Final Approval of the GuideAfter the Principal Investigator incorporates the suggested changes into each chapter, a final draft in near-press-ready format will be submitted to the PMS for final review and approval. Near-press-ready format means that all pages and all graphics, tables, and illustrations shall be in final form, and in compliance withthe full, CMYK graphic standards approved by the PMS and by ASHRAE staff.

Task 4: Publication of the Guide Upon approval by the PMS, the Principal Investigator and chair of the PMS will work with the ASHRAE SpecialPublications staff to publish the design guide. The PI will prepare the final inDesign files for publication. ThePI shall provide all files as a complete, press-ready, preflighted inDesign book file, and shall also provide theoriginal files for any embedded graphics which were not generated within inDesign itself. The PI shall alsoprovide a complete double-sided color laser proof for both the book and cover.

Task 5: Propose Draft Text and Graphic for a New Handbook Chapter Using the approved final text and graphics for the design guide, the Principal Investigator will draft proposedparagraphs for a new c hapter in the ASHRAE Handbook titled Dedicated Outdoor -Air Systems forVentilation. The PI shall create these candidate paragraphs and supporting tables and graphics, in the format required for the current printed edition of the ASHRAE Handbook, and submit them to the PMS for approval.Upon approval by the PMS, the PI shall provide the PMS with the text and graphic files, and allow the PMS toforward these to the cognizant technical committees which have been assigned the task of creating this newchapter.

Deliverables:Progress, Financial and Final Reports, Research or Technical Paper(s), and Data shall constitute the deliverables(Deliverables) under this Agreement and shall be provided as follows:

a.

Progress and Financial ReportsProgress and Financial Reports, in a form approved by the Society, shall be made to the Society through itsManager of Research and Technical Services at quarterly intervals; specifically on or before each January1, April 1, June 10, and October 1 of the contract period.

Other Information to Bidders :

1) Proposed Detailed Outline: The detailed outline included in this work statement is based on input fromthe Project Monitoring Subcommittee and participants of the ASHRAE Handbook Improvement Workshop. The input comes from practicing design, contracting and building operations professionals,and also from manufacturers of DOAS systems and their applications engineers and service technicians.The PMS believes this is a good start on a comprehensive table of contents for this book, but it is not set in stone. The PMS believes that, after the Principal Investigator has performed his/her own independent user research, there may be subjects which must be added to this outline, and perhaps somerestructuring may help to make the information mor e accessible and useful. Note, however, that if the PIsproposal does not address the issues described in the attached outline, it shall be deemed non-responsive.

2) User Review: The goal of this project is to publish a design guide which is engaging and easy-to-read, inaddition to being comprehensive and technically accurate Accordingly, the PMS suggests that if the PIwants to demonstrate that the guide is likely to succeed on this high level, he/she might considerrecruiting a small group of readers from the target audiences for the design guide, who would read andprovide comments to improve the readability, clarity, and utility of the content of each chapter. If such agroup included readers from outside the usual ASHRAE membership, it could help limit the current problem of ASHRAE publications being perceived as out of touch with the needs of anybody other thanacademics, researchers, and designers of tall buildings.

7/28/2019 1565-TRP

3) Style and Content Dos and Donts: ASHRAE publications are designed for many audiences and manypurposes. This publication is aimed at everyday user needs, as opposed to the needs of the internationalresearch record, or the narrow and deep technical precision of journal articles. For example, thispublication should not read like an ASHRAE standard, which must use legally-accurate code language.Nor should it read like a paper written for ASHRAEs Journal of HVAC&R Research. Still less should it look like or read like the background information in Chapter 8, Thermal Comfort, of the ASHRAE Handbook Fundamentals. That chapter provides extensive, clearly-written, and potentially very useful

background information on thermal comfort but it does not describe how a designer should go about actually achieving thermal comfort.

This design guide will be a step-by-step guide which emphasizes design guidance over interestingbackground, and one which emphasizes the economic and annual energy use associated with usingdedicated outdoor-air systems for ventilation. It must also look broadly, just as the designer must do: it must show how DOAS has been integrated into the overall building and HVAC design for maximumconstruction economy and minimum annual energy use.

4) Model Books: A list of publications which exemplify the design and writing styles preferred for this book is included below. All of these publications are written in an engaging style. Several also have an invitingand easy-to-read layout, typography and rich graphics, which are what the PMS is seeking, to assist thecontinuous improvement of ASHRAE books.

Books which exemplify either the writing or the graphic style (or both) which are required for thisproject:

and papers listed in the References section of this work statement, both currently serve on the PMS forthis project. Accordingly, neither Lew, Stan, nor Lews consulting firm will be a bidder or a subcontractorfor this contract.

5) Team Experience: This is fundamentally a book-writing project. Accordingly, the prospectivecontractors proposal should demonstrate a clear understanding of the skill requirements by includingthe names and experience of the specific team members who will be providing the writing, layout, and

graphics for the design guide, along with those individuals who will provide the project management andbasic research into user needs. Further, the proposal should include both PDFs of sample pages as wellcommercially-printed, physical examples of similar four-color books or other publications which havebeen written, designed, or illustrated by these specific team members.
