Form R405-2023 Florida Energy Efficiency Code for Building Construction

We provide services that guarantee compliance with the Florida Energy Efficiency Code through Form R405-2023. By reviewing and certifying building plans, we help enhance energy performance while meeting state energy efficiency standards,
supporting clients in sustainable building practices.

Florida Building Code: Energy Conservation – Mandatory Requirements

Rual Design LLC ensures all projects align with the mandatory energy conservation standards under the Florida Building Code (FBC). These requirements help clients meet FBC standards, ensuring their buildings are energy-efficient and code-compliant.

● Insulation Requirements: Minimum R-values, such as R-19 for ceilings, to support efficient temperature regulation.
● Air and Duct Leakage Testing: Verify that air leakage rates stay below acceptable thresholds and ensure minimal duct leakage for efficient HVAC performance.
● Building Envelope Compliance: Ensuring that commercial buildings meet standards for thermal emittance, solar reflectance, and air leakage.
● Energy-Efficient Equipment: Recommending and certifying the use of high-efficiency equipment for state buildings.
● Solar Energy Device Integration: Where cost-effective, we offer assessments for solar heating and cooling solutions.

2020 Energy Performance Level (EPL) Display Card

The EPL Display Card provides precise data on the energy performance and efficiency levels of building components, ensuring that clients meet transparency and compliance standards while promoting energy-conscious construction practices.

2020 Air Barrier and Insulation Inspection Checklist

Air Barrier and Insulation Inspection is critical in minimizing energy loss. We conduct detailed assessments of insulation placement and air barriers, ensuring the building’s energy efficiency aligns with regulatory expectations.

Manual J (Load) Project Summary

We do Manual J Residential Load Calculations, an essential step for designing an HVAC system that matches a building’s specific heating and cooling needs. Our experts use Manual J calculations to:

● Provide a tailored analysis of a building’s heating and cooling needs, a step above general rule-of-thumb methods.
● Accurately assess heat loss, factoring in internal gains from occupants and equipment for reliable comfort levels.

Manual S (Equipment Sizing) Compliance Report

The Manual S Compliance Report guarantees that HVAC equipment is accurately sized and capable of meeting the comfort conditions calculated by Manual J. This service validates that the HVAC system has adequate blower power for consistent
airflow across the ductwork.

Manual D Duct System Summary

Our Manual D Duct System Summary offers precise duct sizing and layout services. Utilizing Rhvac’s duct-sizing tools, we optimize HVAC distribution for efficient air circulation and temperature regulation, aligned with Manual D standards.

COMcheck Report

We provide COMcheck Reporting , to ensure that new commercial constructions meet IECC (International Energy Conservation Code) or ASHRAE Standard 90.1 requirements. COMcheck Reports are essential for commercial energy compliance and project approval, supporting energy-efficient building practices.

REScheck Report

REScheck Report calculates residential energy compliance using DOE-developed software. REScheck provides a cost-effective way to achieve IECC Energy Code compliance through calculated trade-offs across building components, a vital resource for residential project approvals.

Why Head Load and Energy Calculation Matters?

Head Load and Energy Calculations are essential for designing and operating energy-efficient buildings. These calculations determine HVAC system loads and ensure correct equipment sizing, ductwork layout, and energy compliance. Meeting these standards reduces energy costs, prevents regulatory issues, and enhances comfort for occupants by maintaining indoor temperatures consistently.

Head Load and Energy Calculation FAQs

Why should I choose Rual Design LLC for Head Load and Energy Calculation?

At Rual Design LLC, we utilize the latest methodologies and compliance tools to provide accurate head load calculations that improve building efficiency and meet all regulatory requirements.

What is included in the Florida Energy Efficiency Code compliance for my project?

Our service includes an in-depth review and adherence to the Florida Energy Efficiency Code, including Form R405-2023, insulation checks, air leakage tests, and energy-efficient equipment recommendations.

Does Rual Design LLC provide compliance reports for both residential and commercial buildings?

Yes, we provide COMcheck for commercial buildings and REScheck for residential properties, ensuring full compliance with state and federal energy codes.

How do you calculate HVAC loads for different seasons?

Using ACCA’s Manual J, we conduct seasonal HVAC load calculations based on heat gain and loss, along with internal factors such as occupancy, ensuring year-round comfort and efficiency.

What is the difference between Manual D and Manual J?

Manual D serves as the industry standard for accurately sizing HVAC supply and return ducts. Building upon the calculations from Manual J, Manual D ensures ductwork is properly sized to deliver optimal heating and cooling distribution to each room.

Is Manual J for Commercial Buildings?

The industry gold standard for conducting commercial HVAC load calculations is the method outlined in the ACCA’s (Air Conditioning Contractors of America) Manual J.After completing the load calculation, you will have a precise BTU figure to help select the ideal HVAC equipment for the space.

What is Manual S for HVAC?

ACCA (Air Conditioning Contractors of America) Manual S outlines precise procedures for selecting HVAC equipment based on calculated loads and design conditions from Manual J. It uses OEM (Original Equipment Manufacturer) data to define the acceptable range for HVAC equipment capacity relative to the Manual J load calculations.

One of the easiest contractors I've worked with in a long time. Understood everything with minimal questions. Communication and understanding of the project was great.

Tom Lapham, Business Owner

Amal is quick, precise and skilled. He doesn’t need a lot of directions and can use his engineering judgment. He’s professional and respectful. Would definitely work with him again.

Hady M, Professional Engineer, MI

Amal continues to amaze me with each project I have him on. He's a solid engineer and is a great communicator. Those two traits are getting rare in our industry. I wish him the best of luck and highly recommend him.

Kelvin Chang, Kelvin Consulting, FL

HIGHLY recommended!! Thank you Team Rual for your excellent work as always. Simply put: they are absolutely one of the best Mechanical Plumbing and Electrical engineers I know. He not only prepares comprehensive, accurate and finely drawn plans for mechanical, plumbing and electrical drawings (for both commercial and residential), he also prepares plans on time and on budget! I'll be sending him a new project in just a few minutes.

Karen Wilkins, Wilkins Studio, CA.
