13、 102 Committee (SP-102) representing the variousparticipating organizations that worked collaboratively to produce this document. Whilethe document was produced under the organizational mantle of ASHRAE, much of theheavy lifting was done by representatives of the ASHRAE technical and standardsprojec
14、t committee members, the American Institute of Architects (AIA), the Illuminat-ing Engineering Society of North America (IESNA), the New Buildings Institute (NBI),and the United States Department of Energy (DOE). Within ASHRAE special thanks goto members of Standing Standards Project Committee 90.1
15、(SSPC 90.1), the TechnicalCommittee on Building Environmental Impact and Sustainability (TC 2.8), and theTechnical Committee on Systems Energy Utilization (TC 7.6) for the participation oftheir representatives on the SP-102 committee.No document of this type and scope, with a very limited timeline a
16、nd with a diversegroup of collaborating partners, would have been possible without the firm guidanceprovided by the members of the Cognizant Committee. Without the vision for this docu-ment provided by 2002-2003 ASHRAE President Don Colliver as part of his presiden-tial theme speech, as well as his
17、steady hand as chair of the Cognizant Committee, thisdocument would likely not have been produced. The well-focused scope and purposefor the Advanced Energy Design Guide developed by the Cognizant Committee pro-vided a clear roadmap for the SP-102 committee to follow in producing the document ina ti
18、mely manner.During the eight-month development cycle of this document, the SP-102 committeeconducted three review periods designed to gain input at the concept stage, the technicalrefinement stage, and the final stage of the document. Many comments were receivedfrom members of the partner organizati
19、ons, as well as from others in the HVACthus the goals and strategies relating to cooling and lighting should receive the highestpriority. Conversely, in Duluth the goals and strategies relating to heating and lightingshould receive the highest priority. Table 2-1 (page 11) presents four goals, along
20、 with specific strategies for achievingenergy savings in new construction. Reducing loads (Goal 1) both internal and externalis the most basic. Matching the capacity of energy-using systems to the reduced loads(Goal 2) is also important. Oversized systems cost more and do not operate at their opti-m
21、um efficiency. Higher efficiency equipment (Goal 3) will use less energy to meet anygiven load. Thus, high-efficiency equipment, in systems whose capacity matches peakloads, serving a building designed and constructed to the lowest practical loads, willresult in the lowest energy use and cost. And f
22、inally, Goal 4 addresses the integration ofbuilding systems to increase energy savings potential. Figure 2-1. Stages of design.CHAPTER 2INTEGRATED PROCESS FOR ACHIEVING ENERGY SAVINGS 5Figure 2-2.

The OPR is a written document that details the functional requirements of a project and the expectations of how thefacility will be used and operated. This includes
31、strategies and recommendation selected from this Guide (see Table 2-1 and Chapter 3) that will beincorporated into the project, anticipated hours of operation provided by the owner, and basis of design assumptions made. The OPR forms the foun-dation of what the team is tasked with accomplishing by d
32、efining project and design goals, measurable performance criteria, Owner directives, bud-get, schedules, and supporting information. Quality assurance process depends on a clear, concise, and comprehensive Owners Project Requirementsdocument (see Chapter 4, “Quality Assurance,” QA3 for more informat
33、ion).CHAPTER 2INTEGRATED PROCESS FOR ACHIEVING ENERGY SAVINGS 7QUALITY ASSURANCE: I N -HOUSE OR THIRD PARTY?Users of this Guide may debate whether to use outside third parties or in-house staff for the quality assurance (QA) tasks in the design, construction,and acceptance phases of the project. A c
34、ase can be made for eitherapproach depending on project budget, design complexity, capabilities of thedesign and construction team, and availability of local commissioning exper-tise. While both approaches can be effective, building owners should insistthat the QA tasks be done by a party who is ind
35、ependent from the designand construction team. Independent review ensures that “fresh eyes” areapplied to energy performance QA.Where the in-house approach is deemed to be in the best interests of thebuilding owner, the QA tasks are best accomplished by personnel with nodirect interest in the projec
36、t. For example, qualified staff working on otherprojects could be assigned as disinterested parties to check and verify thework of their colleagues. However, building owners can expect to get themost independent QA review from outside third parties. Indeed, most of theliterature on building commissi
37、oning and energy performance QA recom-mends or requires independent outside reviews.In either case, building owners should expect to bear the cost of 8-24 pro-fessional staff hours to carry out the recommended QA work scope in chap-ter 4 depending on project specifics.Quality Assurance: During the d
38、esign process the design team docu-ments its design assumptions (basis of design) and includes them in theOPR. A party other than the installing contractor, architect, or engineer ofrecord should review the contract document and verify that it incorporatesthe OPR and the associated strategies contai
39、ned in this Guide before thestart of construction. The owners agent, if qualified, can provide the requiredreview. This review along with subsequent inspection, testing, and reportingis referred to as “commissioning.” The reviewer provides the owner anddesigners with written comments outlining where
40、 items do not comply withenergy efficiency goals. Comments should be resolved and any changesrequired completed before start of construction. The owner may choose touse an outside third-party to perform this review. Once the Design Phase is completed, the party that is independent of thedesign and c
41、onstruction team fulfils the quality assurance role to ensure thatthe goals, strategies, and recommendations are actually installed andachieved. This Guide provides recommendations to ensure that the goals,strategies, and actions selected are properly executed during the laterstages of the building
42、life-cycle in chapter 4 under “Quality Assurance.”8 ADVANCED ENERGY DESIGN GUIDE FOR SMALL OFFICE BUILDINGS2. DESIGN PHASEIn this critical Design Phase, the team develops the energy strategies into buildingplans, sections, details, and specifications. The sequence of many design decisions,such as bu
43、ilding and glazing orientation, as well as other identified strategies in thischapter, have a major impact on energy efficiency. They must, therefore, be made muchsooner in the process than is typically done. The following steps, presented in sequence,identify the appropriate time in the process to
44、apply specific recommendations from thisGuide. Energy in the Context of Design Phase ProcessActivities Responsibilities Where to Find Information1.
