Consensus is defined by the American National StandardsInstitute (ANSI), of which ASHRAE is a member and which has approved this standard as an ANS, as “substantial agreement reachedby directly and materially affected interest categories. This signifies the concurrence of more than a simp

It has not been pro-cessed according to the ANSI requirements for a stan-dard and may contain material that has not bee

27、n subjectto public review or a consensus process. Unresolvedobjectors on informative material are not offered theright to appeal at ASHRAE or ANSI.)FOREWORDThe original Standard 90.2 was published in 1993, andrevised editions were published in 2001 and 2004. TheASHRAE Board of Directors voted in 199

28、9 to place ASHRAEstandards on continuous maintenance, permitting the standardto be updated several times each year through the publicationof approved addenda to the standard. Starting with the 2001edition, the standard is now published in its entirety everythird year. This schedule was intended to a

29、llow the standard tobe submitted and proposed by the deadline for inclusion orreference in model building and energy codes. All approvedaddenda and errata will be included in the new edition everythree years. This procedure allows users to have some cer-tainty about when new editions will be publish

30、ed.This 2007 edition of the standard has several new fea-tures, which can be viewed in brief in Appendix C of this docu-ment or online at www.ashrae.org. The committee welcomessuggestions for improving the standard. Users of the standardare encouraged and invited to use the continuous maintenancepro

31、cedure to suggest changes. A form, Submittal of ProposedChange, is included at the back of this standard. The commit-tee will take formal action on every proposal received.The Standing Standards Project Committee is continu-ally considering changes and proposing addenda for publicreview. When addend

PURPOSE The purpose of this st

33、andard is to provide minimumrequirements for the energy-efficient design of residentialbuildings.2. SCOPE 2.1 This standard provides minimum energy-efficiencyrequirements for the design and construction ofa. new residential dwelling units and their systems and b. where explicitly specified,1. new po

34、rtions of residential dwelling units and theirsystems and2. new systems and equipment in existing dwelling units.Note: There are no requirements in this standard thatapply to new portions of residential dwelling units and theirsystems, nor to new systems and equipment in existing dwell-ing units.For

35、 the purposes of this standard, “residential dwellingunits” include single-family houses, multi-family structures(of three stories or fewer above grade), and modular houses.This standard does not include “transient” housing, such ashotels, motels, nursing homes, jails, and barracks, or manu-factured

36、 housing. 2.2 This standard applies to the building envelope, heatingequipment and systems, air-conditioning equipment andsystems, domestic water-heating equipment and systems,and provisions for overall building design alternatives andtrade-offs. 2.3 This standard does not apply to a. specific proce

37、dures for the operation, maintenance, anduse of residential buildings; b. portable products such as appliances and heaters; andc. residential electric service or lighting requirements. 2.4 This standard shall not be used to abridge any safety,health, or environmental requirements. 3. DEFINITIONS, AB

38、BREVIATIONS,ACRONYMS, AND SYMBOLS 3.1 Purpose. The purpose of this section is to define allterms, abbreviations, acronyms, and symbols unique to thisstandard. 3.2 Scope. These terms, abbreviations, acronyms, and sym-bols are applicable to all sections of this standard. Definitionsas contained in ASH

39、RAE Terminology of Heating, Ventilation,Air Conditioning, fenestration assemblies,including all glazed surfaces and sash and framingelements; and door assemblies. Areas of vents, grilles, andpipes are excluded. area of all fenestration assemblies: interior surface area ofsuch assemblies including al

40、l glazed surfaces (such aswindows, skylights, and sliding glass doors), sashes, curbing,or framing elements that enclose conditioned space. For doorswhere the daylight opening area is less than 50% of the doorarea, the fenestration area is the daylight opening area. For allother doors, the fenestrat

41、ion area is the door area. area of all floor assemblies: interior surface area of suchassemblies that enclose conditioned space. area of all opaque wall assemblies: gross area of exteriorwalls measured on the exterior consisting of all opaque wallareas (including foundation walls, between-floor span

42、drels,peripheral edges of floors, etc.) that enclose conditioned space(including interstitial areas). assembly: portion of an envelope component represented byan arrangement and connection of building constructionmaterials with a specific thermal transmittance or thermalconductance. conditioned spac

43、e: an enclosed space within a building that isprovided with mechanical heating and/or cooling energy.envelope component: major section of the entire envelope,such as the opaque walls above grade, ceilings, slabs, floors,glazings, doors, or walls below grade. fenestration: all light-transmitting asse

44、mblies in a buildingenvelope, including the glazing material, sash, frame, andpermanently affixed external or internal shading devices,where such component assemblies enclose conditioned space.heat trap: a device or arrangement of the piping entering andleaving a water heater, constructed to counter

45、act the convec-tive forces of the heated water (thermosyphoning) duringstandby periods.heated slab: concrete slab-on-grade floor containing wires,cables, pipes, or ducts that transfers heat to the conditionedspace. living unit: one or more rooms designed or used as living quar-ters providing complet

46、e, independent living facilities for oneor more persons, including permanent provisions for living,sleeping, eating, cooking, and sanitation. 4 ANSI/ASHRAE Standard 90.2-2007multi-family structure: building of three stories or fewerabove grade containing three or more living units other thantownhous

47、es, including a manufactured building (modular). prescriptive design: design of a living unit or building of thesame size and occupancy type as the proposed design thatcomplies with the prescriptive requirements of this standard.The prescriptive design includes specified assumptionsconcerning shape,

48、 orientation, HVAC, and other systemdesign features. The prescriptive design is used to generate thecompliance requirement for the annual energy cost method. proposed design: design of the living unit or building to beconstructed. The design takes into account all qualities,details, and characteristics of the building that significantlyaffect the use of energy, such as construction, geometry, orien-tation, exposure, materials, equipment, and renewable energysources. sash crack: sum of all perimeters of all ventilators, sashes,
