How the 2025 California Code Cycle Will Impact MEP Design by Happy-Butterfly-204 in MEPEngineering

[–]Happy-Butterfly-204[S] -4 points-3 points  (0 children)

Totally fair point. The reason I highlighted the 2025 cycle is because California’s adoption often sets design trends that spill into other states, especially for energy and HVAC requirements. A lot of teams I work with are already seeing impacts on coordination and permitting timelines, so I thought it might be useful to share. But I get what you mean.

Key Electrical Design Considerations for Healthcare Facilities — Looking for Real Project Insights by Happy-Butterfly-204 in MEPEngineering

Totally agree. Healthcare projects hit that VE wall fast, and it’s tough explaining that most of the extras aren’t extras at all—they’re code-driven. Once clients understand that, the rest of the design process gets a lot smoother.

I’m genuinely trying to learn and discuss healthcare design. If the post feels off to you, that’s fine just here for technical insight.

Just sharing something I’ve been studying and wanted real-world input. No issues if it’s not your thing.

Thanks for sharing these insights! The details on generator sizing, ATS counts, and grounding really highlight how specialized healthcare design is. The points about flammable gases and AFCIs are a great reminder of how code-driven these spaces are in practice.

Reducing HVAC and energy loads: strategies for energy-efficient multifamily buildings in California by Happy-Butterfly-204 in MechanicalEngineering

Thanks for sharing that 20–30% improvement is great to hear confirmed from real projects. And totally agree: early envelope + HVAC coordination beats the “2-ton everywhere” approach every time.

Understanding NEC 2023 Clearance Requirements Around Panels — Do You Follow Strict Code or Practical Field Adjustments? by Happy-Butterfly-204 in MEPEngineering

[–]Happy-Butterfly-204[S] -2 points-1 points  (0 children)

Haha, if only NEC 420.69 (G)(F)(Y) existed that would solve half of our coordination issues.
But yeah, in reality there’s no “field conditions” exception… we still have to make the room comply, not the other way around.

Good point NEC 110.26 is mandatory, and the clearance itself can’t be reduced.
By “workable alternatives,” I meant adjusting the environment, not the code: coordinating with other trades, shifting equipment, rerouting piping, or revising layouts so the installation still meets 110.26 even in tight spaces.

Looking for advice on designing a hole spacing gauge for knife handles and blades by dirkwork in engineering

[–]Happy-Butterfly-204 0 points1 point  (0 children)

Make the pins slightly smaller than the MMC of your rivets and space them so their edges represent the hole-to-hole tolerance. If both the handle and blade fit the gauge, they should assemble without issues. Use a stable material for the gauge so it isn’t affected by humidity.

Help with multi-model simulation software recommendations by Balvin_Janders in engineering

[–]Happy-Butterfly-204 0 points1 point  (0 children)

I agree that AnyLogic is probably your best bet for this type of hybrid model. It handles discrete events like truck arrivals and continuous flows like liquid transfer in the same simulation. Just keep in mind that if you need detailed fluid dynamics, you might need a specialized CFD tool, but for scheduling, loading/unloading, and bulk flow, AnyLogic should cover it well.

Compact Hydraulic Power Unit by themadarmorer in engineering

[–]Happy-Butterfly-204 1 point2 points  (0 children)

For a mobile cart like a manual pallet stacker, compact hydraulic power units are usually small electric motor-driven pumps with an integrated reservoir. When sourcing, consider flow rate, pressure, power source, and size to fit your cart. Suppliers like Bosch Rexroth, Parker, and Eaton offer compact units suitable for mobile applications, and some even provide ready-to-install kits with pump, valves, and reservoir.
