Title 24 HVAC

Commercial Title 24 HVAC Calculations

Mandatory T24 HVAC Calculation Services

All new and alteration commercial projects will require Title 24 compliance reports for HVAC system to ensure your project is designed to meet the newest commercial HVAC requirements. These are part of the bare minimum residential calculations required for new construction projects. They may also be accompanied by Title 24 Envelope and Lighting if the project is to be constructed to completion and occupied immediately with no further development. Commercial shell only projects may require these calculations for all projects as bare minimum compliance proof, if the HVAC is to be installed prior to occupant development.

The purpose of these calculations is to ensure that the project designs meets the newest codes for non-residential HVAC design, as listed in the non-residential codes and standards. We make a digital model of your project and can help you specify HVAC equipment, hot water systems, and ventilaltion requirements  to ensure the overall design meets compliance goals for non-residential building design.

We offer certified Title 24 commercial HVAC calculations that are computed for the highest possible compliance levels for your projects. In some instances where the envelope cannot comply, it may be required to perform these calculations in conjunction with envelope or lighting, so that they can take the credits of the other calculations, rather than creating a shell assembly with high direct cost specifications.

If you have a project that will be in need of these services, please call us at (209)538-2879.

 

Single line diagram

 

In power engineering, a one line diagram or single line diagram (SLD) is a simplified notation for representing a three phase power system. The one line diagram has its largest application in power flow studies. Electrical elements such as circuit breakers, transformers, capacitors, bus bars, and conductors are shown by standardized schematic symbols. Instead of representing each of three phases with a separate line or terminal, only one conductor is represented. It is a form of block diagram graphically depicting the paths for power flow between entities of the system. Elements on the diagram do not represent the physical size or location of the electrical equipment, but it is a common convention to organize the diagram with the same left to right, top to bottom sequence as the switch gear or other apparatus represented. A one line diagram can also be used to show a high level view of conduit runs for a PLC control system.

 

Balanced systems

The theory of three phase power systems tells us that as long as the loads on each of the three phases are balanced, we can consider each phase separately. In power engineering, this assumption is often useful, and to consider all three phases requires more effort with very little potential advantage. An important and frequent exception is an asymmetrical fault on only one or two phases of the system.

A one line diagram is usually used along with other notional simplifications, such as the per unit system.

A secondary advantage to using a one line diagram is that the simpler diagram leaves more space for nonelectrical, such as economic, information to be included.

 

Unbalanced systems

When using the method of symmetrical components, separate one line diagrams are made for each of the positive, negative and zero sequence systems. This simplifies the analysis of unbalanced conditions of a poly phase system. Items that have different impedance for the different phase sequences are identified on the diagrams. For example, in general a generator will have different positive and negative sequence impedance, and certain transformer winding connections block zero sequence currents. The unbalanced system can be resolved into three single line diagrams for each sequence, and interconnected to show how the unbalanced components add in each part of the system.

Title 24 Envelope

Commercial Title 24 Envelope Calculations

Mandatory T24 Envelope Calculation Services

All new and alteration commercial projects will require Title 24 compliance reports for lighting to ensure your project is designed to meet the newest shell envelope design requirements. These are the bare minimum residential calculations required for new construction projects. They may also be accompanied by Title 24 HVAC and Lighting if the project is to be constructed to completion and occupied immediately with no further development. Commercial shell only projects will require these calculations for all projects as bare minimum compliance proof.

The purpose of these calculations is to ensure that the project designs meets the newest codes for non-residential building design, as listed in the non-residential codes and standards. We make a digital model of your project and can help you specify insulation, wall assemblies, window elements, and roof and foundation paramters to ensure the overall design meets compliance goals for non-residential building design.

We offer certified Title 24 commercial envelope calculations that are computed for the highest possible compliance levels for your projects. In some instances where the envelope cannot comply, it may be required to perform these calculations in conjunction with HVAC or lighting, so that they can take the credits of the other calculations, rather than creating a shell assembly with high direct cost specifications.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Title 24 Lighting

Commercial Title 24 Lighting Calculations

Mandatory T24 Lighting Calculation Services

All new and alteration commercial projects will require Title 24 compliance reports for lighting to ensure your project is designed to meet the newest Title 24 lighting codes. These are usually done in conjunction with Title 24 HVAC and Envelope if the project is to be constructed to completion and occupied immediately with no further development. Commercial shell only projects may defer this until the tenant develops the project, but the final development efforts must provide T24 lighting compliance as well.

The purpose of these calculations is to ensure that the project designs meets the newest codes for non-residential building design, as listed in the non-residential codes and standards. We make a digital model of your project and can help you specify lighting in day use areas, common areas, food services areas, retail ares, etc, to ensure you do not exceed the watt capacity per sq footage for that rated space for the purposes of lighting.

We offer certified Title 24 commercial lighting calculations that are computed for the highest possible compliance levels for your projects.
