**Problem:** Salt-laden ocean air corrodes HVAC coils, electrical panels, and metal plumbing components within 3-7 years if not properly protected. Standard inland equipment specifications fail prematurely in Manhattan Beach's marine environment, causing $15,000-$30,000 replacement costs and disruption to occupied homes.

**Manhattan Beach Example:** An oceanfront home on The Strand experienced complete HVAC system failure after only 6 years when contractor-specified standard equipment corroded beyond repair. The homeowner faced emergency replacement during peak summer months, with temporary portable cooling units costing $4,000 monthly while new marine-grade equipment was sourced and installed—total loss exceeded $45,000.

Corrosion-resistant specifications add 8-12% to equipment costs but extend service life from 6-8 years to 18-22 years, saving $30,000-$50,000 in replacement costs over typical homeownership periods. Learn more about sustainable engineering design incorporating long-life materials.

**Problem:** Manhattan Beach architecture emphasizes ocean views through floor-to-ceiling glass, often 30-50% of exterior wall area. Large south and west-facing windows create massive heat gain (15,000-25,000 BTU/hr for typical great room), making Title 24 energy compliance challenging without compromising architectural vision or installing expensive triple-pane glass.

**South Bay Example:** A Hermosa Beach homeowner received plan check corrections requiring either reducing window area by 40% or upgrading to $85,000 worth of high-performance glass to meet prescriptive Title 24 requirements. Neither option was acceptable—reduced windows eliminated ocean views, while glass costs exceeded budget.

Our Title 24 expertise saved the Hermosa Beach client $65,000 by designing a performance-compliant solution with $20,000 in HVAC and insulation upgrades plus 6kW solar system—maintaining full ocean views while achieving better-than-code energy performance.

**Problem:** Modern luxury homes feature sophisticated automation controlling HVAC, lighting, shades, audio/video, security, and pool systems. Lack of coordination between MEP engineers and automation contractors results in incompatible equipment, inadequate control wiring, or systems unable to communicate—requiring expensive retrofits or compromised functionality.

**Manhattan Beach Example:** A newly completed custom home's $75,000 Control4 automation system couldn't control the HVAC equipment because the MEP engineer specified an incompatible thermostat system. Retrofit required replacing all zone thermostats and installing interface modules, costing $8,500 and delaying occupancy by 3 weeks.

Early coordination adds minimal design time but prevents the $5,000-$15,000 retrofits and delayed occupancies common when MEP and automation systems aren't engineered together.
