HVAC CONTRACTOR NOTE: THIS DESIGN WAS CREATED FOR HEAT LOAD AND ENERGY CODE CALCULATION PURPOSES ONLY. INSTALLING HVAC CONTRACTOR MAY USE OR MODIFY THiS DESIGN AS NEEDED TO SATISFY THE PERMIT JURISDICTION - OF THE BUILDING CODES WILL VARY BY JURISDICTION AND PLANS EXAMINER DESPITE THE BUILDING CODES BEING "UNIFIED". ALL PERMIT COMMENTS MUST BE ADDRESSED BY THE INSTALLING HVAC CONTRACTOR. INSTALLING REQUIRED TO SON THE CALCULATIONS FOR PERMITTING. INSTALLING HVAC CONTRACTOR HAS THE OPTION OF PROVIDING ALTERNATE HVAC DRAWINGS AND CALCULATIONS. HVAC NOTES - FLORIDA BUILDING CODE 6TH EDITION - EFFECTIVE 12/31/2017 THIS DESIGN COMPLIES WITH 6TH EDITION FLORIDA BUILDING, RESIDENTIAL, EXISTING RESIDENTIAL, MECHANICAL, AND ENERGY CODES. RESIDENTIAL BASIS OF DESIGN / CONTRACTOR NOTES: These HVAC drawings, h eat load calculations and energy calculations ns are based on the architectural drawings provided for permit application. This HVAC design and specifications are In accordance J manual with 8 -o t u 8th edition room by room heat load calculation proc edure. This design incorporates DOE "Right Size HVAC Design Guide'view online hops://www.nrel.gov/docslfyl2osti/53352.pdf. For duct design: h s: /(ener ov/ i gn ttp gy g s tes/prod/files{2013/12ff5/cq5_duct_splitter_box_beach.pdf. Right size hvac systems are designed to operate continuously during. climatic design conditions - outdoor climatic design conditions are listed in manual J table I (cooling season outdoor temperature examples: Tampa=91, Sarasota=92, St. Petersburg=93) and the indoor temperatures are fixed by the energy code section FEC302 at 72 degrees for winter / 75 degrees for summer. Single stage cooling equipment will have no reserve equipment capacity included for record breaking outdoor temperatures, unusually low indoor temperatures, entertaining large amount of occupants, or any other item not listed on the "Total Building Summary Loads" page - shown on these hvac drawings. Forequipment seleC ! ton designed to neutralize outdoor ea c t weather auditions that can include h g , t t the highest site recorded outdoor temperature, a lower than 75 degree indoor temperature, and occupancy quantities larger than code allowances, see section FEC403.7.1.3 for selection of staged cooling equipment. The lowest operating capacity of staged cooling equipment can be no greater than 15% of the heat load calculations performed at the climatic design conditions (or the closest equipment capacity match available that neutralizes both the sensible and latent heat toads). The highest capacity of staged cooling equipment has no sizing limitations. HVAC installing contractor must use Manual D duct design procedure for designing the larger duct system associated with the staged capacity oversized equipment - or contact the original designer for an updated HVAC system design. Using the architectural construction drawings, ACCA HVAC design procedures were performed: (1) room by room heat load calculations are performed to determine the buildings thermal zones and room b room demands in accordance with m y th antral J 8th edition heat load calculation procedure (2) the heat load calculations were used to select the HVAC equipment capacities in compliance with manual S equipment selection procedure (3) the room by room demand calculations were used to design the duct system in accordance with manual D duct design (4) room air device type, size, and location were based on the rooms required cfm demand, the duct type, and room geometry, in accordance with manual T room air distribution selection procedure (5) Florida energy calculations were performed based On the ACCA hvac design procedures shown above. Note: if a duct zoning control system is shown with multiple thermostats that are served from a single hvac system, Manual ZR was used for the thermal zone grouping and bypass duct design. All calculations performed are data linked to the 3D CAD energy modeling software program that is specific only to this building. For detailed building envelope information (component layers, insulation R values, NFRC glass values, component types and colors, quantity, etc.) see "Total Building Summary Loads" page shown on these hvac drawings. HVAC installer g must field inspect the building envelope component types and sizes prior to any HVAC installation - be sure the building constructed matches the "Tote! Building Summary Loads" page, the room by room floor plan layout, and the energy code forms. Building envelope construction practice "semi tight" was used in the building infiltration calculations, field verify the building envelope (air barrier in contact with the thermal barrier) fully encapsulates the conditioned space. HVAC Installer must field verify sealed draft stops exist that are isolating the wall cavities from the exterior and/or hot vented attic spaces. Buildings with hot vented attic spaces require the air and thermal barriers to be located at the ceiling plane. Buildings with unvented attics / or single assembly roofs (solid flat, law slope, sealed pitched, open web flat truss) require the air and thermal layer be located at the roof plane. Note: acoustical the ceilings are not air barriers, paper faced insulation is not an air barrier - thermal layers in contact with a grid ceiling are ignored in the heat load and energy code calculations. The room air devices, air cfm values, and branch duct sizes shown per room are based on the peak cooling season design conditions with hvac equipment capacities based on manual S equipment selection procedure for he buildings O O p t !d ngs specific site location. This peak demand makes up approximately 15% of the cooling season, the remaining 85 la of the cooling season (part load conditions) requires dedicated dehumidification equipment if year round control of indoor moisture content is expected. Year round moisture control is not part of this construction drawing and requires the latent heat load calculations are performed at part load design conditions, resulting in latent demands at least 20% higher when compared to the peak design conditions. Dedicated dehumidification equipment is required to control moisture content year round in Florida. Dehumidification equipment (Honeywell DH-90 or Ultra -Air XT150H) will monitor and control moisture content year round using a humidistat or dew point se nsor. Provide ducted dedicated dehumidifier(s) for buildings that contain an unvented "sealed attic" space (example: spray foam insulation at roof deck underside or roof is insulated above the roof deck). Mount the dehumidifiers) in the sealed attic near the roof peak. For buildings with a hot vented attic space, the dehumidification equipment is ducted to the conditioned space and controls the moisture content inside the conditioned space using a humidistat or dew point sensor. For healthier and cleaner indoor air, install a Plasma Air Model 600 ionizer (contact Cyril John 813 888 9000 / Tom Barrow Co.) + a large capacity HEPA filter as shown on the HVAC equipment schedule. These HVAC drawings, heat load calculations, and energy code forms were based on the architectural drawings provided for permit application. Any modifications to the building room layout, occupancy amount, building use or classification, building compass orientation, or building envelope component material type and / or size must be communicated to the original HVAC designer. HVAC Installer should red line sketch on these HVAC drawings any field changes to be made during construction and submit the "as built"red line sketch to the original HVAC designer for review and redesign - prior to any further HVAC installation. Alternate air ducts sizes and air device sizes must be equal to the listed size shown, don't exceed a 3/1 aspect ratio on alternate duct sizes. Don't install a cooling system into a building thatis missing o fu ll building envelope. Installing ng HVAC contractor must provide a copy of the "permit set" HVAC drawings, HVAC calculations (Manua!'s J S D T ZR}, and energy code form s to the building owner for approval. Installing HVAC contractor must perform the "owner survey" as shaven in manual J 8th edition, Appendix 1, to discuss desired indoor temperatures, filtration, indoor air quality, year round moisture control, health issues that require special indoor conditions, interior mounted heat producing equipment (both latent and sensible heat outputs), occupancy amounts above manual J maximums, and any information not shown on the "Total Building Summary Loads" page shown on these HVAG drawings. CODE OFFICIAL + HVAC CONTRACTOR NOTES: Florida Residential Code section abbreviations: FBC = Building, FMC = Mechanical, FEC = Energy These HVAC drawings are not intended to show exact detail of every item required to meet the code requirements, see the isometric details for code section compliance references. The proposed duct routing is general in nature, field co nditions and building structure may dictate the exact mounting configuration of the HVAC system(s). Florida building code sections are listed for each HVAC drawing symbol to be used by the installing HVAC contractor and code official(s). Installer should reference the code sections prior to fabrication or installation of any HVAC system component. These HVAC drawings comply with the Florida Building Codes 6th Edition (2017-2020) sections FBC101.4.2, FBC101.4.6, FBC105.3.1.2, FBC107.3.5 "Mechanical" Plan review criteria. 1) HVAC installation must comply with the 6th edition Florida building codes, energy conservation codes, and mechanical codes effective 12/31/2017. Obtain all required permits and inspections per code sections FBC105, FBC107, and FBC110. 2) Ventilation air provided per FBC1203 + FMC401.2 + FEC403.6. This design includes mechanically induced controlled ventilation for buildings that contain a forced air duct system, pressurizing the building interior during air handler operation, provided by a ventilation air duct and motorized damper as shown. In cases when the ventilation rate is satisfied by the building infiltration rate, no ventilation air duct will be shown. The ventilation rate may also be satisfied by use of properly sized windows to the outdoors per FBC1203.5, manually operated by the occupant. For large buildings with few occupants, the building envelope infiltration rate may satisfy the minimum ventilation rate required, see "Total Building Summary Loads" page for infiltration rate. Small buildings with many occupants will usually require a ventilation air duct, motorized damper, and ventilation air duct routed to an approved exterior location, see "Total Building Summary Loads" page for ventilation air cfm amount. A mandatory blower door test, FEC402.4.1.2, must be performed to quantify the building's natural infiltration air cfm rate and determine the design ventilation air cfm amount will successfully pressurize the building's interior. The motorized ventilation air damper is dual controlled by both "run-time" and "manually on" control cycles. Installer may also add an air handler fan cycler to provide automatic air exchange during part load conditions. Interlock the ventilation air damper motor with the air handler fan motor for "run time" cycling. The occupants may also select "fan -on" cycle for continuous ventilation when the outdoor conditions are favorable (low heat and low moisture content). 3) Coordinate location of all equipment, fans, air devices, and building penetrations with the general contractor. Coordinate air device locations with the electrical contractor (smoke detectors), G.C. , and building owner - the proposed hvac air device locations are shown in the ideal location per Manual T room air device selection procedure, design alternate air device locations per Manual T. HVAC installer must field verify clearances and accessibility prior to fabrication or installation of the HVAC components. Protect the building structure per FMC302. Provide accessibility for elevated equipment per FMC306.5. Fabricate and install HVAC system components per FMC304 + FBC1307, and product manufacturers envelope penetration detail, FBC107.3.5 wind data for wall and roof penetrations, HVAC product installation instructions, HVAC equipment manufacturers installation instructions, and AHRI energy + equipment manufacturers expanded capacity ratings must be available on the construction site at time of code official inspections per FBC110. 4) All exterior building penetrations and exterior mounted HVAC equipment, wall vent caps, roof vent caps, intake air vents, and relief air caps, etc. must comply with FBC1609 wind loads. HVAC installing contractor must supply engineered product or equipment ANSI/AMCA 540 test information for attachment to the building envelope component per section FBC1609.1.2. A structural engineer's sealed drawing detail may be required for exterior equipment mounted above ground level per FBC1510.10. This hvac design does not provide structural, equipment, or hood tie down details. See structural engineer's drawings and details for equipment support and tie down info when equipment manufacturers engineered data is not available. 5) All duct sizes shown are clear interior "free area" duct dimensions based on FMC603.2 manual D duct design. Add 3" to listed sizes for R-6 exterior duct dimensions - add 4" to listed sizes for R-8 exterior duct dimensions. Fiberglass duct board shown is equal to Knauf 1.5", R-6, fabricate and install per SMACNA standards. Flexible ducts shown are equal to Atco 36 series R-6 class one air duct, not limited in length perFMC603.6.1.1. For prescriptive energy compliance method using form FEC402-2017, use R-8 supply ducts as required by energy code section R403.3.1. Construct all ducts per manufacturer's installation instructions and SMACNA standards for a maximum 1" w.g. Suspend and support the ducts from the building structure per FMC603. Use 26 gauge sheet metal or rigid foil face fiberglass duct board for rigid duct penetrations of private garages per FMC603.7 and protect ducts per FMC607. Mastic seal all ducts installed outside the building's thermal envelope per UL-181 and FMC603.9. Provide accessible volume control dampers in branch ducts per FMC603.18. General exhaust ducts used for exhaust fan duct, clothes dryer duct, make up air duct, and residential cooking appliance duct up to 14" in diameter (or equal free area in rectangular) are constructed from 28 gauge sheet metal "snap lock pipe", ", use SMACNA standards for required gauge of larger metal ducts, mastic seal ducts per table FMC603.9. Use flexible air ducts or 28 gauge sheet metal "snap lock pipe" for ventilation air ducts. Test ducts > 40 linear feet when using energy code compliance method 402 as required by FEC403.3.3. 6) Provide a condensate drain piping system per FMC307, and a refrigerant piping system per FMCI107. Extend condensate drain discharge 12" minimum from the building exterior wall, discharge to grass or other approved location, a condensate drywell may be required. Provide piping and supports for both condensate and refrigerant piping per FMC305. 7) Provide a balanced return air system per FMC601.6. All enclosable rooms require a 1" undercut on the interior door, allowing about 30 cfm of air relief per 30" wide door. Habitable spaces require door undercut plus a means for air transfer or a ducted return air. Pressure differentials across the restricted room can't exceed .01 inch w.g. Enclosable rooms located on the building exterior envelope should be balanced slightly positive. Size ducted transfer air ducts free area 1.5 times larger than the supply air delivered to the enclosed room(s). Size direct through wall Or door grilles at 50 square inches of grille free area to 100 cfm. 8) Attic mounted equipment must contain a shut off device to alert the home owner if the primary condensate drain line is not working properly. Using 16 point bold text, Post a "home owner notice" on the electrical service panel alerting the home owner that the HVAC air handler is located in the attic space, see FEC403.3.6 for full compliance description and "notice to home owner" language required. Provide a sealed attic access panel for hot vented attics, a safe workers access deck, an attic light fixture with switch, and an electrical plug outlet. 9) This design complies with climate zone 2A of the Florida energy conservation code design conditions FEC302, 72 degree heating set point and 75 degree cooling set point. Compliance demonstration is provided by energy conservation code form R402 prescriptive or R405 performance depending on construction type. The building envelope details are shown on the HVAC drawings basis of design (see "Total Building Summary Loads") as required by FEC303.1. HVAC heat load calculations and HVAC equipment capacity selection per section FEC403.7.1.1 and FEC403.7.1.2. Air distribution thermal insulation layer as required by FEC403.3.1 and FEC405.5.2. Duct sealing as required by FEC403.3.2. Refrigerant piping insulation per FEC403.4. And HVAC equipment controls per FEC403.1. 10) Upon completion of the HVAC system installation, per manual D chapter 16, test equipment operating capacities for both cooling and heating to verify the equipment is functioning to the listed capacity. Verify the air handler total air flow cfm matches the HVAC equipment schedule or heat load calculation minimum system airflow rate. No duct system is self -balancing, adjust each room's branch duct volume damper to achieve the listed air flow values shown or to meet the building owner's needs. Use the air device volume damper for the last 10% of air balance to avoid noise at the air device face. Room air flow balance for buildings with concealed ducts can be accomplished during the "rough in" stage of construction, prior to concealment of ducts. With the building air barrier fully intact, install and operate the air handler until proper air flow is adjusted per room, a balanced return air path must also be present. Use a self -compensating air flow hood for airflow measurements, perform air balance procedure in accordance with manual B or NEBB standards. When required by code, provide the air balance report to the building owner and code officials. A blower door test must be performed to verify that the building envelope natural leakage rate does not exceed the infiltration or ventilation cfm rate shown on the "Total Building Summary Loads" page, shown on these drawings. 11) HVAC sequence of proper operation: The thermostat is set to "auto" mode and will monitor the conditioned space temperature and provide heating, cooling, and ventilation when required. Upon a call for heating, the air handler fan interlock will open the ventilation air damper -and operate the indoor fan and heat t ucondenser and/or electric heat strip until the space conditions are satisfied - use a 72 degree thermostat setting during the heating season. Upon a call for cooling, the air handler fan interlock will open the ventilation air damper and operate the indoor fan and heat pump condenser until the space conditions are satisfied - use a 75 degree thermostat setting during the cooling season. During favorable outdoor conditions, when the temperature and humidity is low - the thermostat may be set to "fan on" for continuous air circulation and introduction of ventilation air. For newly constructed homes to be energy code compliant (FEC403.1), the HVAC installer must set the programmable thermostat to provide heating up to 70 degrees and cooling down to 78 degrees. Be sure not to overcool the conditioned space - overcooling a building is defined as a temperature lower than the dew point temperature for the interior conditioned space - most buildings can easily be driven to dew point temperatures during part load conditions. Overcooling a building successfully requires specialized HVAC equipment and controls. The heat removal (sensible heat) and moisture removal (latent heat) must be de -coupled and independently controlled for buildings to achieve temperature's lower than the "dew point safe" energy code set point of 78 degrees.
