Design standards are what ought to be built, not what must be built. Before The Architect
INTRODUCTION
The term "schedule" in a designer house plan -
- Generally applies to tables of information herein under (as opposed to "details," which are usually annotated drawings) and
- Also may apply to prescriptive and descriptive text and drawing
- Herewith, nearly two dozen house plan schedules that Before The Architect (BTA) uses selectively in its house design and construction designer house plan drafting
- This is, in part, a unique presentation; no one this designer knows of or has heard about goes this far in residential design
- Note well that this work is reduced from the 78-page "Schedules Design Standards" chapter of House Construction Design Standards 2Q07 Edition
- ENVIRONMENTAL DESIGN SCHEDULE
- Leads all others, indicating over two dozen circumstantial parameters and related guidelines that directly and indirectly affect house design and house construction
- Sets design and construction in existential context
- Addressed summarily on this website at http://searchwarp.com/swa134338.htm in "House Design – Environmental Standards Schedule" and in-depth in House Construction Design Standards
- WINDOW SCHEDULE
- Pretty standard across better-prepared house plans, though formats vary
- By-house window type, dimensions, house frame opening, etc.
- Cross-reference to identify on house elevations and house plan views
- Presentation is majorly benefited by foreknowledge of the clients' choice of maker and model; otherwise, generic metrics prevail until a chosen supplier works its wares as closely to plan specs as stock materials are available [rarely do our clients go custom all around the house]
Comment: House windows are dimensioned in inches, width first and length second, further distinguished as between application to masonry and non-masonry surrounds.
Comment: BTA prefers Marvin Integrity – size options limited but usually sufficient, types good, muntin styles improving, durability very good to superior, price points competitive, especially if you can buy directly from a local distributor. While lacking in transom alternatives in the Marvin Integrity line, there appears to be a workaround via Parrett Manufacturing Company, Inc., 810 Second Avenue East, P. O. Box 440, Dorchester, WI 54425-0440, P=715-654-6444, F=715-654-6555, http://www.parrettwindows.com
- Special notes can ensue, for example
- Tempered glass not only to code, but for kid's nonsleeping area spaces, emergency egress, and so forth
- Mull or mullion
- Depth of inset
- Layout to centerlines
- Leave fills, tints, and such to clients' guidance from window supplier professionals
- Coordinate with house floor plans, house elevations, residential lighting and emergency egress schedules
- HOUSE DOOR SCHEDULE
- Pretty standard across better-prepared house plans, though formats vary
- By-door hang type, surface, style, dimensions, swing or hand, etc.
Comment: Swing or hand can be quarrelsome, especially swing which can be variously defined based on which side of a house door you're standing – best to identify site of lock jamb by compass or closest house face and swing to a specified space.
- Cross-reference to identify on house elevations and house plan views
- Presentation is usually not majorly benefited by foreknowledge of the manufacturer – metrics for house doors are way more standardized than for house windows
Comment: House doors are dimensioned in feet and inches, width first and length second
- Layout to centerlines
- Special notes can ensue, for example
- Swing-away hinges
- Adaptable hang of pocket doors
- Door sidelites
- Door transoms
- Self-closing and –latching
- Boring
- Security features
- Coordinate with house floor plans, house elevations, possibly, residential lighting schedule for natural lighting if glazed
- EMERGENCY EGRESS SCHEDULE
- Identify openable size to code and to site
Comment: Easily takes a well-recognized concern off the table
- May adapt
- To identify possible future sleeping areas
- To include high-use, non-sleeping areas for kids, the mature, the physically challenged, etc.
- Can require careful consideration in -
- Story-and-a-half structures
- High-rising shed roof ridges
- Some hip roof and intersecting gable roof designs, etc.
- Coordinate with house floor plans, house elevations, and house window schedule
- RESIDENTIAL LIGHTING DESIGN NATURAL ILLUMINATION, OR DAYLIGHTING, SCHEDULE
- The basis of the residential lighting Daylighting Schedule is to –
- Assess code compliance as to natural light intrusion to sleeping areas
- Assess natural light intrusion to nonsleeping areas
- By-space percentage of clear glazing surface area to the surface area of the space so illuminated, including commentary
- The basis for the residential lighting Daylighting Schedule is codified –
- The author's launching pad for residential lighting daylighting sufficiency is the International Residential Code 2003, Section R303.1 with a close read of both Exceptions 1 and 2, while respecting the cross-referenced Section R310
- 8% of a sleeping area's surface area must be represented in "aggregate glazing area," which term is not defined as far as AG can tell AG has interpreted it to mean translucent or transparent glaze and not muntins and sash and such
- Better window manufacturers can make the extent of "aggregate glazing area" or its surrogate readily identifiable, e.g., Marvin's "Lite."
- Provides
- De facto statement of compliance
- Cross-check on house window placement and identification in house floor plans and house elevations
- Perspectives on interior nightlighting, heating and cooling, UV and glare intrusion, lines of sight, interior arrangement of furniture and fixtures
- Complicated by
- Limit of uncompromised daylight intrusion maximum at 2.5 times fenestration height (with minor adjustment upwards for lighter interior color and higher reflectivity)
- Fenestration shaded on the exterior, as with a covered porch
- High-rising shed roof ridge
- Intersecting roof ridges
- Story-and-a-half structure
- Interior "open and airy" design objective
- Remediated (usually) by
- Limits to daylighted room depth
- Design modifications, such as
- Selectively taller fenestration
- Supplementary fenestration
- Various forms of roof penetration
- And, as a last resort, continuous service residential lighting
- BATHROOM EXHAUST FAN SCHEDULE
- There are several unusual aspects to the Bathroom Exhaust Fan Schedule
- Bathroom exhaust fans are sited
- An enclosed bathroom fixture gets its own bathroom exhaust fan without regard to site of space
- Some laundry spaces get an exhaust fan, too, for "wet hang" and "hot soak" conditions
- A grill in a covered space gets an exhaust fan - often codified locally
- Exhaust fans are specified by make and model for -
- Air exchange for interior application at not less than 12/hour
- Lowest sones available
- Involve an HVAC pro in designing methods and materials for
- Back-draft prevention and
- Exhaust fan efficiency of design
- CEILING FAN SCHEDULE
- Sized and sited in -
- A table
- An Electrical and Lighting Plan
Comment: Both the Internet and ceiling fan sellers can offer practical advice about fan blade diameter and downrod length
- TRIM GUIDELINES
- Cover each feature group separately
- Distinguish quality level(s), finishes, and sites
- Specify materials and methods where needed and leave latitude where warranted
- Define beyond doubt items such as returns, butts, overlaps, miters, etc.
- A section to-scale and well annotated is always welcome, especially in piecework
- Unless you know the local market, specify generically
- ATTIC VENTILATION
- BTA addresses attic ventilation in four aspects, whether attic ventilation is active or passive
- Code layout on a simplified Roof Plan in house plan view of each attic section to be ventilated and ventilation extent or sites identified
- Net Free Vent Area calculations for each designated area of attic to be ventilated
- Net Free Vent Area notes largely taken from House Construction Design Standards, and adapted as needs be to a particular application
- Specify materials of calculated sufficiency of airflow
- Special care shall be taken to –
- Adequately vent shed roof, portico, cupolas, chases, porch roofs, and the like
- Not undershoot the soffit vent or similar intake airflow targets according to BTA [selected attic surface area/150=net free vent area intake=2x net free vent area exhaust, i.e., hi/2=lo]
- Not diminish airflow dynamics with lower exhausts
- Evenly distribute intakes
- Show your calculations and cross reference to the Roof Plan
- STORMWATER ROOF RUNOFF WATERSHED SCHEDULE
Comment: Note please that BTA's Stormwater Roof Runoff Watershed Schedule is at its core based on and built upon an original publication: "Sizing Gutter Systems: A three-step approach helps you calculate the best size for your house" by Andy Engel, Fine Homebuilding Magazine, #125, p.97.
- This is about sizing and siting stormwater roof runoff gutters and leaders
- By roof plane calculation and analysis of stormwater roof runoff to roof gutters and gutter downspouts, principally to judge roof gutter drain flow direction and gutter downspout layout
- In more complex house plans with more complex roof designs, stormwater roof runoff watershed schedules can give you all sorts of insights as to laying out roof gutters and gutter downspouts to mean the difference to clients between long-term convenience and real misery
- A simplified Roof Plan in house plan view is the template for drawing in roof gutters (lines) and gutter downspouts (circles) and flow directions (arrows) based on the above article's methodology and common sense, working one roof plane at a time
- Marginally increase watershed loads for "fast" roofs – rises over the given table, slate and tile roofing, etc.
- Apply not less than 6" metal roof gutters, and, in some instances by extrapolation, 8" metal gutters
- Leave details of materials and methods to local, professional installers
- Highlight pinch-points or otherwise worrisome aspects of your work or indications
- Show your calculations and cross-reference to the layout
- ROOF SLOPE SCHEDULE
- By plane-slope, this designer thinks that complex roof designed to look a certain way need scheduling
- Complicating factors
- Otherwise lacking a concise reference
- Roof planes slopes derived from other slopes given
- Second citation of key aspects [nothing of importance in a plan set should be presented just once]
- FIXTURE UNIT SCHEDULE
- By-fixture or number of fixtures with fixture units – usually both IRC and UPC metrics
- Of course, the AG leaves final fixture unit toting-up to plumbing contractors; however,
- This schedule comes in handy to collect a large number of varied fixtures (and their units) in one cite, as a cross-reference, especially if interior house elevations of baths, kitchen(s), and such aren't needed, concealed baths are contemplated, and, therewith, possibly leaving the only other reference to fixtures in the house floor plans
- SURFACE AREA SCHEDULE
- Plenty of ways to present surface areas
- Basis distinctions by-level
- Finer distinctions
- Finished
- Unfinished
- Occupiable
- Covered
- Enclosed
- Open
- Screened
- BTA presents these data
- In summary on the Cover Page
- Specific to each level in Floor Plans
- Take care not to count stairwells twice
- FOUNDATION DRAINAGE SCHEDULE
- Drawn onto the Foundation Plan – drainpipe (lines), flow direction (arrows), connections (annotated)
- Usually not needed
- Complicating factors
- Too much water in too little drainpipe
- Unvented crawlspace drainage
- Connecting unvented crawlspace drainage to perimeter drainage
- Below-L0 or -crawlspace traverse
- Site walls
- Courtyards
- Slabs-on-grade abutting perimeters
- METAL CONNECTOR SCHEDULE
- The author does not often get a request to specify metal connectors or otherwise have a need to do so
- In conditions of high wind-resistance and seismic and circumstances of truss applications, engineers rule, not this old designer
- More often than not, would that metal connectors developed as an important aspect of a design, they'd be identified in -
- Details
- Major Section, as in a Full Wall Section ridge-to-footing section
- Floor Plan
- Roof Plan
- Foundation Plan
- When scheduled
- They're specified by a building authority having jurisdiction (not a frequent occurrence) and
- They'd be Simpson Strong-Tie, virtually always
- Whether or not scheduled, there'd be cautionary annotation wherever applied to preservative-treated members that the metal connectors explicitly can withstand that preservative
- HVAC SCHEDULE
- The subject is a career of itself and BTA does not specify most materials and methods; however,
- Basics can be scheduled in regard to -
- Conduit
- Connections
- Sealing, especially
- WINDOW HEADER AND DOOR HEADER SCHEDULE
- There's a lot more to prescribe for window headers and door headers than their dimensions, among them and more importantly to BTA
- Low moisture content of material from drop ship to application and closing-in, in order to minimize shrinkage and, therewith, minimize diminution of performance metrics and finishing failures
- Wall stiffener in -
- Narrow return conditions
- "Window and door wall" designs
by
- Taking them into nearby corners
- Tying to ceiling and roof structure
- Steel strapping from top plates across the window header or door header and down onto jacks
- The author used to define window header and door header constructs one at a time
- Took a while
- Got kind of repetitive
- The author switched to texted schedule, salient points of which are -
- Definably higher quality materials
- Flitch plate(s)
- Span table adjustments upwards
- Member stability sourced in several ways
- BUILDING PERMIT SCHEDULE
- Now and then a building authority having jurisdiction (AHJ) in the area of our building site will publish a building permit checklist for new residential construction and residential remodel
- BTA can and does complete such building permit checklists when plan sets get involved, which they usually do, because AHJ's are not accustomed to BTA's level of detail and cross-reference, the learning curve for which could slow down the permit process in order to sort things out
- Entries include
- Cross-reference to drawn Sheet and Detail and Schedule
- Open subjects
- Noting by whom to be subsequently determined, for example, engineering calculations in order to spec various beams
- Alerting the AHJ of compliance work from others
- "Not applicable" when it is
- Questioning or cautionary comments, for example, preferred siting of certain fire-blocking attic partitions and to-be-concealed bathroom plumbing, respectively
- Respond directly to every item in the building permit checklist – no blanks – be unambiguous
- RESIDENTIAL LIGHTING DESIGN INTERIOR LIGHTING, OR NIGHTLIGHTING, SCHEDULE
Comment: This is about a residential lighting design guidance system for residential lighting on interiors for clients' aging eyes the aim of which is to tailor lighting design to a house in a practical manner so as to be not only sensitive to its occupants' well-being, but also easily specified and readily recognized in retail settings and by lighting professionals. BTA's residential lighting design meaning and metrics summaries reside elsewhere on this website at "Interior Residential Lighting Design for Aging Eyes, The Basics and The Math – Parts 1 & 2," respectively, in http://searchwarp.com/swa124510.htm and http://searchwarp.com/swa124664.htm, respectively
Comment: Note well that BTA's approach to interior residential lighting design is unique in methodology, aggressive in application, and dependent on current and developing fluorescent lighting technology overall and switching the likes of Lutron's.
20. Residential Lighting Design Schedule
- Apply BTA's lighting design metrics
- By space, including each closet and each major pathway
- By areas with a space, e.g., ambient for overall, task at work areas
- Note to depreciate published (initial) lumen rating of bulbs by 20%, being this designer's conservative shot at so-called "maintenance lumens" after accumulated dust and dirt and time take their toll on a bulb's illuminance (to be managed at purchase or factored into lumen targets, with reference as to which course of action the designer's taken)
- Schedule lumen targets by space, number, and functional type
- Notes can be extensive
- Basis of the Residential Lighting Design Schedule
- The Schedule arises from the Electrical and Lighting Plan layout(s)
- Summarize the Lighting Design Schedule space-by-space in small text blocks on the Electrical and Lighting Plan sheet(s)
- Luminaires by number, type, and site
- If you need to be specific about number, type, and site of luminaires as, say, in a vanity space or sizing and siting a dining table pendant, then do so;
- Otherwise, leave it to lighting professionals to work through nearly unimaginable opportunities to get the designed lumens where and how you've designated
21. RESIDENTIAL LIGHTING DESIGN LIGHT FLUTTER (AVOIDANCE) SCHEDULE
- BTA now presents its residential lighting design guidance to avoiding light flutter in two places –
- The Electrical and Lighting Plan, as annotated boundaries to-scale around a ceiling fan, scaled diameter symbol
- A table defining minimum offsets from fan centerpoints for fan blade diameters, downrod lengths, and beam spreads applicable and reasonably imagined
- Thoroughly disclose the methodology underlying the design calculations
- For further on this subject, please reference http://searchwarp.com/swa123990.htm on this website
22. FINISHING
- The purposes of the Finishing Schedule include -
- To allow time for forethought on myriad considerations
- Provide a cross-check on Specifications, Details, other Schedules, house Floor Plans, house Elevations, and other drawn sheets
- Present a sense of both finishing style and the inherent level of materials and methods to construction bidders
- The Finishing Schedule is among the last of a plan set's entries to be fully authored
- By-space, by-surface area (each interior wall by compass or house-side direction), inside and out
- Detail text on materials and methods is grouped and keyed for schedule inserts to house Floor Plans, house Elevations, etc.
- BTA forms this schedule and fills it in as far as possible, then forwards it to the clients for their review, repair, and return
- This schedule can be the most tedious of all for its comprehensive enterprise and mind-boggling specificity
- This schedule can grow to the largest table in the plan set
- BTA tries, particularly on the exterior, to get as much of this schedule's focus satisfactorily settled, in order to deal with the more numerous considerations of interior finish
23. OVERHANG SCHEDULE
Comment: This schedule is based on "Designing Overhangs With The Sun in Mind" by Jerry Germer, Journal of Light Construction, May, 2001, 2 pages. Read for yourself.
- Design and prove design by presenting calculations of optimal overhang depth to window glaze height based on jobsite latitude
- Takes the guesswork out of –
-
Best daylighting to radiant heat gain and loss on South-facing façade, through the Seasons
-
Being green
-
Window height to soffit depth options
