FOREWORD Although the majority of new buildings are safe comfortable and designed to provide effective protection

against moisture-related problems there are a certain number of buildings built each year that do experiencemoisture or mold problems Whether this number is now increasing and whether the increase is due to the greater emphasis on energy-efficiency measures today is a widely debated topic This standard is not concerned to answer

either of these questions but to provide guidance on how to best design buildings with adequate moisture control

features Given its position as a leader in the proper design of heating ventilating and air conditioning

equipment ASHRAE is uniquely qualified to provide such guidance

During the last two decades a number of computer simulation tools were developed to predict thermal

and moisture conditions in buildings and the building envelope In addition to their use as forensic tools in the

investigation of building failures these computer models are increasingly used to make recommendations for

building design in various climates However results obtained with these models are extremely sensitive to the

assumed moisture boundary conditions For instance during winter in cold climates the moisture conditions in

walls depend greatly on the indoor humidity conditions Thus a consistent approach to moisture design demands a

consistent framework for design assumptions or assumed ldquoloadsrdquo The question whether or not design features such as vapor retarders or ventilation systems are necessary cannot be answered objectively unless there is a

consensus definition of the interior and exterior moisture boundary conditions that the building is expected to be

able to sustain without negative consequences to itself or its inhabitants This standard formulates design

assumptions for moisture design analysis and criteria for acceptable performance

Ideally a design analysis involves the determination of the probability of failure treating all design

parameters and loads as stochastic variables However sufficient data are often not available to make a full

statistical treatment practical Instead a moisture design protocol will have to be based on a combination of

statistical data and professional judgment where only limited data exist Another judgment involves the choice of

an acceptable probability of the occurrence of damage Although it is common to impose very stringent criteria for

structural design because of safety concerns moisture damage usually occurs over a long period of time and

usually has less catastrophic although sometimes costly consequences An international consensus has emerged

that the analysis should be predicated on loads that will not be exceeded 90 of the time This standard hasadopted this approach

In a moisture analysis for building envelope design the choice of indoor environmental conditions is

extremely important especially for buildings in cold climates This standard opts for a design indoor climate

definition that is based on engineering principles is independent of construction and reflects the influence of

ventilation and air-conditioning equipment and controls that may or may not be part of the building design In

buildings where indoor humidity and temperature are explicitly controlled the building envelope performance

should be evaluated with the intended indoor design conditions In residential buildings indoor humidity is rarely

explicitly controlled and default design assumptions are needed for these buildings In general the standard

encourages designers to use their own design parameter values if they are known and part of the design If they

are unknown or not included in the design the standard provides default values for those loads and parameters

The standard does not address design details that deal with rainwater intrusion plumbing leaks ground

water and water damage caused by natural disasters such as floods and hurricanes While proper design for suchevents is extremely important and damage from such events involves a large percentage of moisture damage in

buildings these issues can be more effectively addressed by codes training of the trades and specific design

guidelines (see Commentary) This standard assumes that appropriate measures have been taken to limit bulk

water entry into the building and building envelope The standard does not intend to replace the judgment of the

design professional Rather it provides a framework for the design professional to identify and consider factors

that are important to the durability and serviceability of the building In addition many items in this standard are

based on incomplete information and are therefore partially based on the best professional judgment of the

standard committee at the time of writing this standard The development of this standard has pointed to many

unanswered questions questions that will hopefully be addressed and answered by research in the near future

INFORMATIVE ANNEX B COMMENTARY ON STANDARD 160

B-1Although this standard applies to all parts of all buildings additional information may be needed for the proper

design of foundations and ventilated cavities such as crawl spaces and attics This standard assumes that

appropriate measures have been taken to limit bulk water entry into the building and building envelope For

B-2Guidance on airtight construction can be found in ASTM E 1677 (see Annex C Bibliography) The design and

installation of a continuous airflow retarder systemair barrier should be durable be capable of withstanding design

wind loads and be continuous over the entire building envelope including continuity at

construction control and expansion joints

junctions between different building assemblies

penetrations and projections through the building assembly (eg pipes through a wall precast cladding

anchors brick ties)

the base of interior space projecting through the building assembly (eg projecting bay windows or larger cantilevered space) and

wallfloor and interiorexterior wall intersections

Refer to the source of this information Di Lenardo et al (1995) for more detail (see Annex C Bibliography)

B-3The source for the definition for Moisture Design Reference Years is International Energy Agency Annex 24

1996 (see Annex C Bibliography)





Page 20 of 24

B-4The choice of EMC80 for initial moisture conditions is based on the criteria for mold growth from IEA (1991)

(see Annex C Bibliography) which states (pp 6-7) ldquoTake for new designs as threshold steady-state water activity

or RH()100 for mold germination bdquoaw‟ = 08 use this value on a monthly mean basisrdquo

B-5During the heating season the indoor design temperature is assumed to be 211degC (70degF) and for the cooling

season 239degC (75degF) if air-conditioning equipment is included in the design Heating or cooling is assumed to

take place based on a 24-hour running average of hourly outdoor temperature Heating is assumed when therunning average falls below 183degC (65degF) and cooling when the running average rises above 211degC (70degF) if

air-conditioning equipment is included in the design When the 24-h running average outdoor temperature falls

between 183degC (65degF) and 211degC (70degF) the indoor temperature is assumed to ldquofloatrdquo at 28degC (5degF) above the

24-h running average outdoor temperature If no air-conditioning equipment is included in the design the indoor

temperature is assumed to ldquofloatrdquo at 28degC (5degF) above the 24-h running average outdoor temperature when the 24-

h running average temperature is above 183degC (65degF)

B-6The simplified method for indoor design humidity is based on data from buildings without air-conditioning

While the standard allows use of this method for air-conditioned buildings it should be understood that humidity

conditions in air-conditioned buildings tend to be lower The intermediate method provides more realistic

conditions for air-conditioned buildings except when the building is cooled by radiant heat or swamp coolers The

simplified method may also produce high values for buildings without air-conditioning in dry climates even withair-conditioning Again the intermediate of or full-parameter analysis would be preferable

B-7Indoor humidity conditions are the result of a water vapor mass balance between water vapor production and

water vapor removal For reasons of simplification Equation 41 accounts for the effect of water vapor stored inhygroscopic materials by using a 24-hour running average Water vapor transfer by vapor diffusion through the

exterior envelope is ignored It also ignores the effect of initial moisture conditions (ie ldquoconstruction moisturerdquo)

on indoor humidity We recommend that Equation 41 also be used when the building is exclusively cooled by

radiant cooling

B-8The numbers in Table 432 are based on published values for residential moisture production rates The

rationale is described by TenWolde and Walker (2001) (see Annex C Bibliography) The values represent the

approximate 70 percentile (ie 70 of homes should have moisture generation rates less than the rates in Table41) Moisture production for jetted tubs is based on Angell and Olson (1988) (see Annex C Bibliography)

B-9The default design ventilation rate for buildings (standard construction) without aThe non-designed ventilation

rate system for standard construction is based on data by Sherman and Dickerhoff (1998) (see Annex C

Bibliography) and represents the 70 percentile of normalized air leakage for new construction (1995) ie 70 of

new homes have an average ventilation rate greater than 02 air changes per hour The default ventilation rate for

airtight construction is set at half that level

B-10The mean coincident design outdoor humidity conditions needed for Equation 44 are reported in the 2005

ASHRAE Handbook of Fundamentals (CD ROM version only see Annex C Bibliography) chapter 28 table 1

columns 9c and 9d They are reported in terms of drybulb and mean coincident wetbulb temperatures Conversion

to humidity ratio can be accomplished using readily available psychrometric tables charts or tools available on theinternet Values for the corresponding design humidity ratio w0 at standard atmospheric pressure can be found in

Annex B or an approximation can be obtained with the following equation

w0 (dbwb) = wwetbulb at saturation ndash 024 (Tdrybulb-Twetbulb)

where wwetbulb at saturation is the humidity ratio of saturated air at the wetbulb temperature (temperatures in degF)

In SI units the formula is


with temperatures in degC





Page 21 of 24

To obtain an approximate adjustment for different altitudes and ambient air pressures multiply the result from

Annex B or the equations above with the ratio of the standard atmospheric pressure (101300 Pa 1569 psi) to the

actual atmospheric pressure

B-11It is recommended that controlled air pressure differences included in the building design be verified by

measurement at the time of building commissioning

B-12This standard does not account for large mechanically-induced air pressures

B-13Equation 45 for buildings over three stories high assumes that the reference pressure (neutral pressure plane) is

at half the building height The pressure difference at the top of the wall of the top floor shall be calculated because

a) it is greater at that location and b) it is in the most detrimental direction (ie from inside to outside in winter

and outside to inside in summer) This assumes that wall design does not vary with building height

B-14 Air Default air leakage rates are based on the minimum leakage rates for an air barrier and rigid sheathing at 5

Pa 2001 ASHRAE Handbook--Fundamentals (see Annex C Bibliography) p 2615 and an assumption of a flow

exponent of 10 and a discharge coefficient of 1

B-15

This standard deals with rain penetration in walls only Roof systems are to be designed and built such thatthere is no rainwater penetration For guidance on good roof design see the NRCA Roofing and Waterproofing

Manual (2001) (see Annex C Bibliography)

B-16The formula for driving rain is a linearization of the formula developed by Lacy (1965) r v=0222Vr h088 (see

Annex C Bibliography) Lacy‟s formula assumes an average droplet size and will tend to overestimate driving

rain because it underestimates the contribution of larger drops ASTM Standard C1601-05 Standard Test Method

for Field Determination of Water Penetration of Masonry Wall Surfaces (see Annex C Bibliography) provides a

table for rain angle as a function of wind speed and of rain intensity where rainfall intensity substitutes for

raindrop size However for our purposes the simple approach of equation 46 is accurate enough especially in

light of the uncertainties in exposure factors and deposition factors

B-17

The exposure factor includes the effects of terrain (roughness and height) topography and obstructions Raindeposition on the wall has been simplified from Figures A and B The maximum values for flat roofed (10) and

pitched roofed (05) buildings are used in the standard The figures show side views of buildings with two different

types of roofIn order to determine an exposure it may be useful to refer to the American Society of Civil

Engineers who maintains a standard entitled ldquoASCESEI-07 Minimum Design Loads for Buildings and Other

Structuresrdquo (ASCE 2005) which contains wind load provisions Within the document are what is referred to as

wind exposure categories that that are used in determining the exposure of the subject building in order to

determine the magnitude of wind load on a building These predetermined exposure categories may be useful in

determining the rain deposition on the design building ASCE-07 exposure categories are

ldquoExposure category B [consists of] urban and suburban areas wooded areas or other terrain with

numerous closely spaced obstructions having the size of single-family dwellings or largerrdquo

ldquoExposure category C [consists of] open terrain with scattered obstructions having heights generally less

than 30 feet (92 meters) This category includes flat open country grasslands and all water surfaces inhurricane prone regionsrdquo

ldquoExposure category D [consists of] flat unobstructed areas and water surfaces outside hurricane prone

regions This category includes smooth mud flats slat flats and unbroken icerdquo

A fourth category was recognized up until 2005 this was ldquoExposure categor y A It consisted of heavily built-up

city centers with tall buildings However [it was determined] that in areas in close proximity to all buildings the

variability of the wind [was] too great because of local channeling and wake buffeting effectrdquo [1] As a result the

user may need to take into consideration local wind activities from regional data collection sources for use on

buildings in these types of areas

81041992)

Figure B Recommended values for the deposition factor FD for walls of buildings with sloped roof (based on British

Standard BS 81041992 which is listed in Appendix D Bibliography)

B-18Rain runoff onto walls may occur from roofs or impermeable non-water-absorbing wall surfaces above such as

windows The deposition factors contain a large amount of uncertainty Calculating rain deposition on buildings is

still an evolving science

B-19Full-scale mock-up tests of rain penetration into exterior walls should include the effect of windows doors andother design details Guidance of this type of testing can be found in ASTM Standards D5957-98 Standard Guide

for Flood Testing Horizontal Waterproofing Installations and E2099-00 Standard Practice for the Specification

and Evaluation of Pre-Construction Laboratory Mockups of Exterior Wall Systems (see Annex C Bibliography)

B-20For reasons of simplicity rain penetrating the exterior wall surface is assumed to be distributed uniformly on

the water water-resistive barrier

B-21Usually the criteria for mold and corrosion are the most restrictive An extensive discussion of failure criteria

can be found in Viitanen and Salonvaara (2001) (see Annex C Bibliography)





Page 23 of 24

B-22The source for the criteria for mold growth is IEA (1991) Annex XIV (see Annex C Bibliography) with added

temperature criteria

B-23Corrosion - Harriman et al (2001) (see Annex C Bibliography) describe a ldquocritical relative humidityrdquo at which

the corrosion rate becomes rapid Clean iron does not corrode until the air is practically saturated but if the air

contains a trace of sulfur dioxide (001) the critical relative humidity is 70 The critical relative humidity for copper is 87 but reduces to 80 rh with a trace of sulfur dioxide Nickel has a critical relative humidity of 70

B-24Fiber saturation of solid wood is usually taken to be around 30 MC oven dry weight basis Fiber saturation of

composite wood products such as oriented strandboard is often lower in the range of 20 to 25
