What is a Title-24?

The California Title 24 Energy Standards, also known as Title 24, Part 6, is a set of regulations aimed at improving energy efficiency in buildings, including residential properties. The Title 24 calculation performance method is a key aspect of these standards, focusing on assessing and optimizing the energy performance of structures.

In the context of residential properties, the Title 24 calculation performance method analyzes various factors to ensure compliance with energy efficiency requirements. Some key aspects include:

1. **Building Envelope Efficiency:** The method evaluates the thermal performance of walls, roofs, windows, and doors to minimize heat transfer and maintain a comfortable indoor environment.

2. **Lighting Efficiency:** It addresses lighting systems to promote the use of energy-efficient fixtures, controls, and technologies, reducing electricity consumption.

3. **HVAC (Heating, Ventilation, and Air Conditioning) Systems:** The method assesses the efficiency of HVAC systems to minimize energy use for heating and cooling, promoting the implementation of high-efficiency equipment and controls.

4. **Ventilation and Indoor Air Quality:** Title 24 considers ventilation requirements to ensure proper air circulation while maintaining indoor air quality standards.

5. **Appliance Efficiency:** It includes standards for energy-efficient appliances to reduce electricity consumption in residential buildings.

The Title 24 calculation performance method employs computer simulations and modeling tools to quantify the energy performance of a building. Compliance is typically measured through the use of software like EnergyPro or other approved tools that simulate the energy usage of a building based on its design and specifications.

Architects and structural engineers play a crucial role in meeting Title 24 requirements by incorporating energy-efficient design elements and technologies into residential projects. Adhering to these standards not only ensures regulatory compliance but also contributes to reducing environmental impact and long-term energy costs for homeowners.
