With that U-factor known, model a wood-framed assembly with a similar or slightly higher U-factor. Thus your form remains easily parsable by a screen reader or reading assistant, and yet displays nicely. What are valid values for the id attribute in HTML? Modifications to the HVAC system that involve replacing the system or components require that the project be registered with a HERS provided.  The simplified Addition and Alteration methods allow for no registration, and as such cannot be used in this case.  Your options would be to use the Performance Approach (which will still required registration) or indicate the HVAC is not being altered, and then submit a separate document via a HERS provider (see www.cheers2016.org) for the HVAC alterations in addition to the envelope documents prepared in EnergyPro. You have input a project with the Number of Dwelling Units input as greater than 2 and the building is designated as having more than 3 Stories. How do I get an Energy Cost estimate report for my project? When modeling Built-up VAV systems that include Fan Powered Zone Terminal Boxes, it is a requirement of the DOE-2 engine that you must have at least two zones. Now verify that you have a valid Energy Factor input for the water heater. Note that a Zone Type of Res Garage is also considered a Lowrise Residential occupancy.  You can now click the Calculate button on the menu bar to rerun your calculations. If you have selected many DOE-2 Reports to be run your file might crash.  Deselect all of the DOE-2 reports then select only the reports you need. How do I get an All Electric Single Family Home to Comply? How can you span columns with this solution? Note that interior surfaces do not need to be input twice. A score of zero or less represents the energy performance of a building that combines high levels of energy efficiency and/or renewable generation to “zero out” its TDV energy use. Also, any entries made on the JA4 tab of the editor (rigid insulation, etc) will not be seen in the Nonresidential performance simulation, so If you need to add rigid insulation you will have to add a layer into the Layers tab. At the Zone level of the tree, Mechanical tab you have specified that the ventilation will come from the HVAC system under the input for Ventilation Type.  The code does not permit the use of the HVAC system as a source of ventilation, you must provide a dedicated ventilation system to ventilate a Hirise Residential Occupancy. In ALL cases, an ADU will require an IAQ fan, verified in the field by a HERS rater. The solution is to create a unique entry for each case, for example create a wall named (e) CONC. Large label's text overrides the input. When modeling conditioned spaces under Title 24, all spaces are required to be ventilated per the code.  At the Zone level of the tree, in the Mechanical tab, you have set the Ventilation to None.  This is not a valid choice, so either choose that it comes from the HVAC system, from an Exhaust Fan, or it is Naturally Ventilated.  Note that the Natural Ventilation choice is only valid for Residential spaces and cannot be used for Commercial spaces. if you wanna do it the tables way its up to you. Go into EnergyPro and open the software activation window by going to Help / software activation, it will look like: Click on the ‘Import’ button and in the ‘Look in’ section, go to where ever you have saved the AUTHENTICATED license.lic file that energysoft sent back to you.  It should look like: If you see ‘license installed’ then you have successfully installed the license.  Go ahead and use the software. When inputting the efficiency of the HVAC system, ensure the value entered is consistent with the type of system being modeled. Select a heated slab-on-grade from the library at the Slab element. In the Report Wizard, Select the report labeled “ECON-1”, and proceed to finish. When describing an HVAC system that uses a water heater to provide the hot ware for the space heat (Combined Hydronic), the software will perform calculations for the boiler that account for both the Domestic Hot Water usage as well as space heating usage. How do I model Quality Insulation Installation? Manufacturers publish both sets of data in their literature, and this same data is also listed in the AHRI listing and sometimes in the CEC equipment directories. In the list that appears above, select the DHW/Boiler library. The EDR is similar to the energy rating index in the 2015 IECC. You will not need to enter every available input in each tab. Dynamically showing/hiding form lines is easy (you just search for the input and hide its parent -> the label), you can assign classes to the whole label making it show error input much clearer (not only around the input field). Credits for re-registrations can be obtained by emailing support@regt24.com. A heated slab floor is a slab-on-grade assembly that has either electric or hydronic heating embedded in the slab. The product is designated as having a Hydronic Heating system but no boiler has been specified. To remove a license key from a computer, go to Help > Software Activation and click on Uninstall License. Your proposed design is likely a Constant Volume system, and thus is going to have significantly higher fan power usage than the Standard building. Select the DHW/Boiler Library in the list that appears above. At the System level of the building tree, in the HERS tab, edit the airflow setting and set this number to a valid rate. It's also expanding my "submit" button to the width of the container. These types of terminal boxes cannot be selected when the system type is a Packaged VAV system. This type of error shows up when opening an older file from a prior code cycle in which the prior occupancy is no longer a valid occupancy in the new code cycle and requires you to reselect a valid occupancy under the new code. The residential Prescriptive compliance rules for alterations limits the window area to 20% of the floor area when your alteration includes an increase of more than 75 sqft of window.  You can either decrease your new window area (altered windows do not count) or use the performance approach for the alteration calculation.
