Electrical design


The HVAC system is the backbone of any building, delivering needed comfort for occupants. However, HVAC systems can be a huge drain on your overhead, especially if they’re not designed for maximum efficiency.

Our licensed engineers won’t just create HVAC designs that maximize efficiency, we’ll also ensure they meet building codes for hassle-free city approval. From floor plans to equipment specifications, we cover every step of the process. Our comprehensive HVAC services come complete with mechanical drafting and design, 3D REVIT modeling, schematic heating, cooling system design, and more.

Electrical Design

Electrical design is the beating heart of any modern building. A haphazard electrical design can lead to wasted energy and high maintenance costs. Reliable systems is about more than just installing equipment, it’s about planning and strategic optimization. We’ll work collectively to customize electrical schematics, power plans, site plans, panel schedules, distribution panels, and more.

Green Construction

Plumbing Design

Plumbing design is an essential part of any infrastructure, responsible for both delivering water and removing waste. But designing an efficient system is about more than just getting water where it needs to go- it’s about optimizing every aspect to save energy, water, and money.

We design systems that provide just the right amount of flow and pressure, while minimizing pumping costs and maintenance. Our engineers develop plumbing designs that adhere to California design codes while optimized for maximum efficiency.

Title 24 Compliance

In 2013, California initiated Title 24, a building energy efficiency standard that regulates how new and existing buildings maintain environmental and sustainable quality. Every building is constructed to optimize for more comfort, lower energy costs, and less carbon emissions.

S3DA Design meets these goals using cutting-edge technology and up-to-date practices. Some of our Title 24 services include calculation, remodeling lighting, Title 24 envelope and mechanical

Solar Design

Solar power is the future of energy, and for good reason-it reduces energy costs and carbon footprint. As of 2020, solar power is mandatory for new construction homes and multi-family dwellings up to three stories. But installing a solar power system can be daunting. We’re at the forefront of the ever-changing solar industry, delivering quality solutions in the renewable energy field. We’ll draft a cost-effective plan designed to meet your construction goals.

Fire Protection

Integrating fire protection is given for any infrastructure. We help map out a crucial schematic diagrams like smoke detection, sprinkler placement, fire alarms, and gas suppression systems.

Moreover, we determine accurate requirements, calculations, and appropriate testing routines. Through maximum efficiency and lower costs, we incorporate measures to prevent, circumvent, and minimize fire damage.

Chief Consultant, Development & Planning at BeGreenLegal Cannabis Consulting

“S3DA contacted me through LinkedIn and while I am usually skeptical of cold messages, I was in need of an MEP engineer so I thought I would give them a shot. After more than a year of working on several projects with their team, I have found them to be responsive, reasonable with timelines and budgets, and willing to stand behind their work. While there are many good engineers out there, S3DA’s customer service stands out as a valuable resource.”
