Dream-Home-wizards-tower

The overall idea of the house, is that it was built by a typical fantasy wizard several millenia ago, and then lost after he passed away. I found it and renovated it while keeping the original character of the house (quirky and natural)

Want to use natural materials as much as possible (wood and stone) while still keeping high energy efficiency.

Repository Notes

rezip.py is from costerwi/rezip and is used to uncompress the freecad files so they work with git better. It is copied into the repo itself for ease of use. The post processing is done using .gitattributes

TODO

• redo third and potentially second floor to get rid of all around walkway and move bathroom towards atrium.
• Reimplement tracked elevator blocking walls in Revit
• work on lighting design more
• rethink layer heights and levels, especially in terms of ceilings and floors.
• rethink basement, maybe shrink down, but keep in mind space for mechanical systems.
• add lighting pipes at ceiling level on all floors around perimeter of cutout
• add in ceiling, 6" dropped ceiling with dark wood panels at least on ground floor.
• think about combining floor 3 and 4 into library/lounge and adding windows or shrinking overall footprint to allow for greater height.
• Add demand column and total column for electrical calcs amperage
• Sink living room area into floor.
• Standardize subtotals row and implement if statement for total amps cell
• How to integrate plants/planters into ground floor. Want feeling of being in jungle.
• Add custom wooden suspended ceilings over certain areas on ground floor, dining and living room, have them on tracks so they can be moved around. Use light source mini can LED lights in suspended ceiling. want to not have "grid" look, potentially have uplights/indirect light either shining through boards, or bouncing off ceiling
• add more windows, especially to bathrooms
• North is oriented towards elevator
• move entrance to south west side
• add patio along east side of house
• add more windows into east wall of house
• put workshop area by elevator and combine half of -1 and -2 to give more ceiling height.
• change wall doors to tracked style
• On floors 1 and 2, have hallway on outside with interior windows in bedrooms
• flow meters on io of water loops for leak detection

Floor space planning

Area of circle 𝜋R²

• Ground floor is 18' radius ==> 1,017.87 ft²
• First floor is 17'3" radius w/ 6' radius hole ==> 821.7 ft²
• Second floor is 16'6" radius w/ 6' radius hole ==> 742.2 ft²
• Third floor is 15'3" radius w/ 6' radius hole ==> 617.5 ft²
• Fourth floor is 15' radius w/ 6' radius hole ==> 593.8 ft²

Total floorspace 3793 sq ft

Load planning

loads from roof level:

• Steel 22 Gauge standing seam conical roof
• Maintance catwalk constructed of steel with open grate composite floor with exterior railing designed to support communication antennas and lighting fixtures. Use live and dead load estimates from theatrical catwalks.
• 4 pick points for 2 ton hoists in central atrium area on underside of beams (want at least a 3x safety factor for each pick point)

General Description

Code notes/references

IBC/IRC

Using IRC/IBC 2018 codes, house probably doesn't fall under the IRC due to the use of heavy timber and concrete construction. The IRC has specific construction styles that it covers, and in the 2018 codes, it primarily covers balloon/platform framing.

Based on this, the house would fall under R-3 residential occupancy. Quoting the code: "Section 310.4 Residential Group R-3. Buildings that do not contain more than two dwelling units"

Section 405 doesn't apply due to exception 1 of 405.1, since the building is sprinklered per §903.3.1.3

section 420.2 separation walls may apply

max height (table 504.3) and max stories (table 504.4) for HT construction in R occupancies is 60 ft (R3 stories 4) with sprinklers according to §903.3.1.2 or §903.3.1.3 , and 85 ft with sprinklers according to §903.3.1.1 (R3 stories 5). All new R occupancies must be sprinklered.

Section 505.3 Equipment platforms are not considered a story or part of the story below. they do not contirbute to building area or number of stories.

May need an exception to Section 712.1.2 unless floors 3 and 4 can count as one story or floor 4 can count as a mezzanine.

§705.8.5 vertical separation of openings. Windows have to be seperated vertically not less than 3ft, unless building is sprinklered with regards to §903.3.1.1 or §903.3.1.2

§705.10 ducts and air transfer openings have to be protected if they are in fire resistance rated exterior walls. §717 may also apply.

equipment shafts:

section 713

need 2 hour fire rating (§713.4) on enclosing walls (penetrates 4 or more floors), as well as top if shaft does not extend to roof and bottom if shaft does not extend to bottom of building.

will need fire rated ceiling, since it will not extend past floor 3. Will extend to bottom of building and terminate in electrical room, which needs the same 2hr fire rated construction as the shaft.

Will need at least 1.5 hr fire rated doors in shaft openings (table 716.1(2))

table 721.1(2) has fire resistance ratings for walls and partitions of various materials

§713.6 shaft walls that are also exterior walls should comply with sections of 705 that apply to exterior walls.

this won't affect the house, since the exterior walls will be much thicker than required for a 2 hr fire rating.

§717 ducts that penetrate shaft walls may require fire dampers. May want to put ventilation ducting not inside mechanical shaft (or not have a mechanical shaft at all)

§803.15 will apply to any false/dropped ceilings, and any interior finishes attached to the concrete walls (stone etc) except for paint.

sprinkler systems

§903.2 exception: server rooms, battery rooms and telecom closets don't need sprinklers if they are provided with smoke detection and separted by at least 1 hr fire barriers from other spaces.

§903.2.8.1 R3 occupancies need sprinkler systems but they may comply with 903.3.1.3

903.3.1.1 is NFPA 13 sprinkler systems

903.3.1.2 is NFPA 13R sprinkler systems

903.3.1.3 is NFPA 13D sprinkler system

May have to install standpipe based on §905.3 and AHJ requirements

§907.2.22 need smoke detection in battery rooms

table 1404.2 - natural stone on exterior wall needs to be 2" thick

§ 1505 - type 4 (HT) construction requires minimum class B roof. Slate roof installed on ASTM D226 type 2 asphalt felt #30 felt is class A, as is standing seam metal roof installed on noncombustible deck, or without roof deck on noncombustible framing.

Can't walk on slate roofs

slate roof should have deflection of 1/720, any other roof needs 1/360

Table 1604.5 - This structure is risk category II

Table 1607.1 Live loads - includes info about catwalks.

§1607.14 Crane Loads - Using this for the hoist loads. Live load is the rated capacity.

IECC 2018

Since the house is 4 stories, the commercial provisions of the IECC apply.

Park County is in zone 7

Minimum requirements for opaque thermal envelope insulation components based on Table C402.1.3. Zone 7 Group R numbers as follows:

Insulation entirely above roof deck needs R-35 continuous insulation Mass walls need minimum R15.2 of continuous insulation. Below grade walls need minimum R10 of continuous insulation. Mass floors need minimum R16.7 continuous insulation joist/framing floors need minimum R30 insulation

§C402.2.2 Mass walls specifications

§C402.2.3 Mass floor specifications

§C402.4.1 Maximum fenestration area not greater than 30% of gross above grade wall area

§C402.5.1 continuous air barrier required

Lighting needs to comply with either §R404.1 or §C405.2.4 and §C405.3

Construction notes

Roof

Conical roof.

Standing seam metal roofing with layers as follows. See for more info. From JLC

• metal roof panels

• Underlayment

• Sheathing

• 2x4 spacers oriented vertically (16" on center) This creates an air gap for venting the underside of the sheathing.

• Sheathing

• Mineral Wool board insulation - Comfortboard 110

• Air sealing - spray foam (maybe)

• Sheathing/ceiling support (may be ceiling material as well)

• Ceiling material (Optional)

• Joists

• Ceiling material (Optional)

Insulation and sheathing sandwitch extends out into overhang over joists. There is a nailer/support around the entire perimeter of the roof, which has the trim over it. The trim is the same material as the metal roof panels.

The vent channel has a fascia board protecting it, with a metal drip edge over it. There is an internal mesh screen in the vent opening.

will need point ridge vent on top.

Catwalk installed over roof using standing seam clamps https://s-5.com/products/utility-solutions/walkways/ and non metallic walkway boards.

Heavy timber framing for roof, probably 8 main joists.

General notes

House is sited so that the elevator shaft is facing north. The elevator shaft is embedded in a hill with the majority of the house with southern exposure.

general style is a combination between medieval and modern. Lots of slate and wood, but open plan layouts and not a lot of walls. Medieval simplicity, with less of hogwarts ornateness on the interior. Old tower - new interior.

HVAC is 4 pipe system with localized ZCUs + zoned radiant heat, as well as a global air recirculation/filtration/humidification system. Also allows for adding local components to HVAC loop such as water cooled computers or mini ZCUs. Windows are also interconnected into the HVAC system so that automatic natural heating/cooling can happen as well.

Lots of greenery and hanging plants/vines on walls. Some used for partitions.

Bathrooms on outside of house have windows

Lighting stuff

Primary illumination on ground floor is provided by WL 72º RGBW LED fixtures (12 per 20A 120V circuit)

Secondary illumination in center of ground floor provided by either RD 72º RGBW LED or WL 72º RGBW LED fixtures (12 per 20A 120V circuit)

Additional RGBW tape under the lip of the stairs/RGBW led spots mounted on the wire of the railings.

For other floors and providing additional illumination on ground floor (or replacing the above depending on cost), are custom built RGBAW led fixtures. These contain an arduino and sensors and use POE for data and power. Sensors include:

• Thermal (wet and dry bulb)
• humidity
• air quality (co2, o2, co, other polutants and gasses, ideally a wide spectrum sensor)
• presence detection (Ultrasonic, infrared, radar)
• light levels

They might also contain additional connections for switches or door/window position sensors.

General Technology

• in wall vacuum system

Radio

• UHF commerical MotoTrbo repeater

• 2M + 70cm + 1.25M amateur repeaters

• HF radio

Network Planning

Datacenter in basement. Dual pfSense routers in failover mode. At least two different fiber lines from different carriers, as well as a satelite link.

Central fiber trunk runs up in mechanical space near kitchen, with at least one POE managed switch on each floor.

Distribution cable is carried in trays that run in the beam interstitial space.

Each light switch and custom light needs a POE network port. Also every universe of DMX needs a network port.

Outlet planning

each "room" needs a lighting outlet which will be manually switched with remote control posibilities. This will be used for an LED floodlight as a backup and to satisfy NEC requirements.

2-3 additional lighting circuits per floor

Ground floor

2 lighting circuits in ceiling for WL lights, at least 2 more circuits in ceiling for other stuff like powered speakers, etc.

Bathroom outlet and lighting circuit

Appliances

Commerical Option

• Hobart LXeR dishwasher
• Hobart HEC5D convection oven

Residential Option

• GE Café French Door Convection Wall Oven

Ground floor

Ground floor is open plan kitchen/living room/dining room. Living room is at the base of the central atrium and is sunken about 1 foot to create a space deliniation. The kitchen has a different flooring material with no seams to allow for easy cleaning. The rest of the flooring is large slate tiles, ideally with irregular joints to look more like a flagstone floor but with the joints sealed against moisture and to allow for easy sweeping.

Living room has a rug, along with couches and a coffee table.

all furniture/appliances are on casters to allow for flexibility, with plug and cord connected appliances and electronics connected to plugs in the ceiling.

Kitchen is industrial and all electric.

Free space can be utilized for workspace if needed

Has powder room.

Floor 1

Master bedroom and office, potentially small powder room depending on convenience of floor 2 bathroom

Floor 2

Living room, a little more medieval/comfortable with chairs and sofas, large bathroom to serve first and third floors, potentially part of library

Floor 3

library, observatory. Has wall mounted bookshelves and reading tables/chairs.

Also has the power and data connections for the truss equipment and any other cord/hose drops in the center of the house.

Floor 4

This has a walkway around the edge in order to get to the second tier of shelving.

potentially have a loft or catwalk in the middle of the room over the beams for the hoist motors.

Floor -1

Has a guest suite as well as a workshop, home theatre and storage.

Floor -2

Has datacenter and electrical distribution gear + storage. Workshop may extend to this floor.

Floor -3

Has HVAC equipment (chillers, boilers, heat pumps etc) for both the house and the datacenter. Also has any potential water/sewage treatment and storage equipment. (gray water, well, septic etc, rain water catchment, etc)
