All You Need to Know to Understand Title 24 Energy Compliance

In 2015, the California Energy Commission chose to push the state toward a goal of being Zero Net Energy (ZNE) for all the upcoming residential construction by 2020 and commercial constructions by 2030. The techniques to achieve the goal of ZNE are mentioned in the energy efficiency codes in section 6 of Title 24 in the California Code of Regulations. 

Title 24 has also guided the program for energy planning in the state since 1978. It has also served as a guidepost for all national as well as global efficiency initiatives. The regulations for Title 24 are updated in every three years to upkeep with the rapid evolving developments in the efficiency technology. 

Let’s have a look at the necessities that are mandatory and then will compare the Prescriptive and Performance paths that would help people to make the best decision for the construction project. 

• Obligatory requirements

The requirements that must be fulfilled are easy to understand,and they should be fulfilled as there are no other paths around them. Although, there are some exceptions for every compulsory requirement and they might or might not apply to the project. 

The exceptions are necessary to save significant costs. Thus it is essential to work with a professional energy modeller and design team for Title 24 in San Diego as well as in other surrounding areas to get valid information on specific project requirements. 

Some very important requirements are shut down the devices on lighting (wall switches) and continuous insulation on the metal-framed infrastructures. In most of the projects, confusion occurs when it comes to choosing the compliance paths. A project can comply through performance or prescriptive path. Let’s discuss more about them. 

• Prescriptive Path

When it comes to prescriptive compliance, it needs a project with detailed requirements for the lighting, envelope, HVAC, domestic hot water as well as other covered processes. This makes the design easy but ultimately increases the overhead costs for the project. Accomplishing the prescriptive necessities indicate the project does not get any credit for a system that outruns the prescriptive level of compliance. 

For instance, LED lighting in some cases exceeds the prescriptive requisites,but no credit is available to install a low performing wall or the windows. 

• Performance Path

The performance path enables you to take the LED credit from the above-mentioned examples and then apply it to lower-performing wall or window. This help in eliminating the costs involved in a project. 

The energy modelling to adhere to the performance tasks require significant amount of time. It is extremely important to educate all the people associated with the project so that they find it easy to pay for higher energy modelling costs later to get a lower total cost.
