Automatic Daylighting Control Acceptance (NRCA-LTI-03-A)
Daylighting control is a method for controlling lighting automatically by regulating the quantity of electric illumination within a building to maintain a set level.
It works best in areas with constant access to natural light, such as lighting adjacent to windows or lighting near skylights.
Title 24 acceptance also supports the daylight controls with its Automatic Daylighting Control Acceptance (NRCA-LTI-03-A) test. This test determines whether or not automatic daylighting systems fulfill the criteria.
Here, we shed light on this vital acceptance test and daylight control benefits. So, learn about its purpose and requirements.
Automatic Daylighting Control Acceptance (NRCA-LTI-03-A)
Benefits of Daylighting Control
The correct functioning of daylighting controls saves energy. Controls over daylighting result in a more accurate estimation of the money saved on electricity.
Controls that are successful in the evaluation decrease the quantity of light output in reaction to the presence of natural light. As a result, a sizeable amount of lighting energy is saved.
These settings also supply ample illumination in any situation during the day. The visual quality will decrease if the control causes the room to get too dark, and the control will eventually be overridden, which will cancel out any savings in terms of energy consumption.
Purpose of NRCA-LTI-03-A
The purpose of Automatic Daylighting Control Acceptance is to confirm that the areas required to have automatic daylighting control have the relevant components installed and are functioning correctly in compliance with the energy standards.
Requirements of NRCA-LTI-03-A
In new construction, daylighting must be installed if the wattage of the primary daylight zones is more than 120W.
In tenant renovations, daylighting must be installed if the wattage of the primary daylight zones is higher than 85 percent of the allowable W/sqft.
It is necessary to install and adequately calibrate a system that, when daylight is present, causes an automatic reduction in the quantity of electric illumination used.
When it comes to any lighting controlled by automated daylighting controls and occupancy sensing controls, the lighting output must be maintained at a level lower than the minimum amount of electricity that either of the two controls will permit.
Controls for automatic daylighting must be constructed in such a way that the power output of the lights does not exceed the bare minimum permitted by each control.
NRCA-LTI-03-A necessitates that if there are additional controls, the light level can either rapidly dim to the level decided by those controls or switch on to full power. It can also be set to the level of light previously set, then gradually dim to the level decided by those controls. Both options are possible depending on whether or not other controls are present.
Summary
Automatic Daylighting Control Acceptance is a process that validates all required components for automatic daylighting control have been installed and are running appropriately in line with energy requirements.

Shut-off Lighting Control Acceptance (NRCA-LTI-02-A)
Introduction
Energy-saving standards contain requirements for lighting controls that are progressively difficult. With each additional layer of complexity, formalizing the lighting control system commissioning procedure delivers great benefits.
These benefits include:
• Improved indoor environmental quality
• Maintenance of suitable illumination levels
• Lighting controls per building design
• Superior energy performance
Depending on the nature of the operation, the Energy Conservation Code mandates various commissioning procedures with varying levels of precision.
In this article, we explore Shut-off Lighting Control Acceptance (NRCA-LTI-02-A). We also present the tips for passing this test.
Shut-off Lighting Control Acceptance
The Title 24 acceptance test is performed most frequently. It puts the auto shutoff feature of a lighting control system to the test.
To demonstrate that you can meet the requirements of this test, all of the significant area lighting, except for emergency lights, must turn off automatically when the room is unoccupied.
To regulate the lights in every location within a room, it is necessary to install an occupancy sensor device.
Here are the crucial tips for you to get the required Shut-Off Lighting Control Acceptance.
• Be familiar with the requirements
In preparation for the Shut-Off Lighting Control Acceptance test, ensure that your project complies with Title 24 criteria throughout the process.
• Utilize lighting controls and fixtures that conform to Title 24 specifications
Ensure that your project’s designs feature lighting systems that comply with Title 24 throughout the process.
You will save a substantial amount of money if you take the time to verify that the lighting fixtures have multilevel dimming, that occupancy sensors are installed, and that everything is programmed correctly in the final phases of the process.
• Ensure the correct programming of all devices
Ensure that you have done a walkthrough and that all components of your advanced lighting control system are functioning correctly (occupancy sensors, daylight sensors, dimmable fixtures, etc.). It is a crucial step to getting NRCA-LTI-02-A.
• Ensure the presence of your electrician
We are well aware that not every endeavor will be successful. Having an electrician present during testing will speed the process if a minor change is required to ensure compliance.
If you keep these five tips in mind, your performance on the test will be outstanding.
Summary
NRCA-LTI-02-A is the most fundamental test, which comprises ensuring that an automatic shutoff mechanism is present in a lighting system.
To pass this test, you need to ensure that all of the principal area lightings, except for emergency lighting, must switch off automatically when the room is generally unoccupied.
The Title 24 standards for commissioning and testing are pretty precise and contain a great deal of detail. However, you do not need to worry about the complexity of the Shut-Off Lighting Control Acceptance (NRCA-LTI-02-A) test, as title24lightinginspection.com is here for you.

Demand Responsive Lighting Control Acceptance (NRCA-LTI-04-A)
Introduction
There are two primary elements for determining the building’s energy usage cost. These are the amount of energy used and the demand for that energy.
Demand response programs help solve problems with the electrical grid’s capacity. The solution lies in controlling how much power customers use.
Demand Responsive Lighting Control Acceptance (NRCA-LTI-04-A) of Title 24 instructs the manufacturer to certify that demand-responsive lighting controls can respond to signals.
Let us discuss this acceptance test with its purpose, benefits and requirements.
Demand Responsive Lighting Control Acceptance
Purpose
Demand Responsive Lighting Control Acceptance (NRCA-LTI-04-A) determines whether or not the demand-responsive control can restrict the lighting system’s power consumption. This consumption should not be more than 85% of its full capability.
During a demand response event, the test verifies that the lighting system maintained a specified level of illumination consistently as expected.
Benefits of Demand-Responsive Control
When power costs are high or the grid is unstable, the owner or manager of a building with a fully functional demand-responsive lighting system can save money.
It is done by reducing the amount of energy that is used for lighting. It involves cutting back on the amount of energy that lightings use. The control not only results in cost savings but also improves the electrical grid’s reliability for each client.
It is important to note that to pass the Demand Responsive Lighting Control Acceptance (NRCA-LTI-04-A), a demand response signal is not compulsory. Instead, the tester ensures that the system can receive and react appropriately to signals.
The demand response system brings the entire electricity the building uses to less than 85%. This total output also maintains the same level of illumination throughout the building.
Requirements
Lighting projects that are larger than 10,000 square feet are required to have the capability to reduce the amount of lighting power automatically. Demand Response Signal accomplishes this goal by using controls. These controls meet the requirements of Title 24 for NRCA-LTI-04-A.
This requirement exempts the areas with a lighting power density (LPD) of less than 0.5 watts per square foot.
Dimming the general illumination is necessary to fulfill the requirements for consistent lighting. I
It is also necessary to have the capacity to reduce the total amount of light by at least 15% for Demand Responsive Lighting Control Acceptance. There is one notable exception.
Areas in which lights cannot be dimmed are exempt from the need to have demand-responsive controls. This exemption is according to the rules or regulations that health and life safety governing bodies set. These are not included in the control systems of the 10,000 square foot limit calculation.
Summary
The Demand Responsive Lighting Control Acceptance (NRCA-LTI-04-A) determines if the control can limit the lighting system’s power consumption.
