COMcheck Software Version 3.9.1 Mechanical Requirements Description 90.1 (2007) Standard The following list provides more delailed descriplions of lhe requirements in Section 4 of lhe Mechanical Compliance Certificate. Requirements Specific To: HVAC System 1 : U 1. Equipmenl minimum efficiency: � 2. For cooling systems<=240 kBtWh,mazimum hol gas bypass capacity must bo no more than 50%�olal cooling capaciry. Requirements Specific To: HVAC System 2 : � 1. Equipmenl minimum eKciency: U 2. In�egra�ed air economizer is required for individual cooling sys�ems over 65 kBtWh or 135 kB1uRi(dapending on Gimale zone),and allows modulation of outdoor air and retum air dampers�o provide up to 100%of the design supply air quantity as outdoor air for caoling.All air economizers shall be capable of aulomatically redudng outdoor air in�ake lo lhe design minimum ou�door air quanlity when outdoor air intake will no longor reduce coding energy usage.Refer lo code Section 6.5.1.1.3(or details on high-limit shutoff control types and settings. U 3. Air ewnomizer dampers can be sequenced with the cooling equipment and not coMmlled exc�usively by mixed aIr temperature. - Exception:Syslem coMrolled 1rom space lemperature(su:h as single-zone systems). � 4. For coolinc�systems=240 kBW/h,mazimum hot gas bypass capacity must be no more than 50%lotal cooling capacity. Requirements Specific To:Water Heater 1 : � 1. Water heatin�equipment meets ASHRAE 90.1-1999 minimum etfidency requirements: � 2. Service water hea�ing syslem design loads for the puipose of sizin�systems and equipmen[must bo delermined in accordance with manufacturers'published sizing guidelines. � 3. �nsulation must be provided for the first 0 R ol oullet piping(or a constant lemperalure nonrecirculating slorage syslern and f�r Ihe inlet pipta between the storage lank and a heat Irep in a slorago system. U 4. TemperaWre contmis must be provided thal allow for staage temperature adjuslmeN from 120'F or Iower to a maximum�emperature compatiblo with lhe intended use excepl when the manufaclurefs inslallalion insWctions speci(y a higher minimum thermostat setting lo minimize condensation and resulting cortosion. Documentation of the installation instructions must ba pmvided to be ezempted trom lhis requirement. � 5. Hoal lraps must be provided on inlet and outlet vertipl pipe risers sarving slorage water heaters and storage tanks not having integral heat lraps and serving a nonredreulating system. Heal traps musl be installed as Gose as practical to lhe storage tank.Acceptable heat treps are either a) a device specifically desi�ned for�he purpose or b)an arrangement of tubing that fortns a loop of 360'F, or c)piping lhat tmm the point of wnnection lo the water heater(inlel or outlel)indudes a length of piping direded downwards before conneCion to lhe mrtical piping of�he supply water or hot water distribution system. Generic Requirements: Must be met by all systems to which the requirement is applicable: 1. Tho system or zone contml must be a proc�rammable lhertnoslat or other automatic control meeling the following criteria: a)capable of setting back lemperature l0 55°F during hea�ing and setting up to BS°F during cooling, b)capable of automatically setting back or shutting down systems during unoaupied hours using 7 different,iay schedules, c)have an accessib�e 2-hour occupant ovartide, d)have a battery back•up c�pable of maintaining programmed seltings lor at least 10 hours without power. Exception(s): - A setback or shutoH conlml is not required on thermostals that conWl systems servirg areas Ihat opf�rata conlinuously. 2. All pipes:,erving space�conditioning syslems musl be insuWted as follows: Hot waler piping for healing systems: 1 in.tor pipes<=1 tl2-in.nominal ci2meter, 2 in.for pipes>7 112-in.nominal diameter. Chilled water,re(ngerant,and brine F�ipinc�systems: 1 in.insulation for pipes<=7 12-in.nominal diameter, 1 V2 in.insulafion for pipes>1 1Y2-In.nominal diamelar. �� Sleam piping: 1 1l2 in.insulalion for pipes<=7 1l2-in.nominal diame�er, 3 in.insulation for pipes>1 1YL-in.nominal diamaler. 6cception(s): - Factory-installed piping within FIVAC equipment. - Pipinc�thal conveys tluids having a dosign operating lemperature mnge between 60°F and 105°F.
