High Performance Homes

What actually makes a home high performance.

“High performance” gets thrown around a lot in custom home building. Here’s what it means when we build your custom home in San Antonio — and why it matters for your energy bills, comfort, and air quality for decades.

What is a high performance home?

A high performance home is built to measurably outperform a standard code-built home in three key areas: energy efficiency, indoor air quality, and comfort consistency. The difference isn’t cosmetic — it’s in the systems, materials, and building-science decisions made during construction.

Most production builders meet minimum code and move on. UrbanLUX goes further — because at the $1M+ price point, your home should perform as well as it looks. Our clients typically see 40–60% lower utility bills compared to standard new construction, and that compounds over the life of the home.

We’ve built 200+ homes in San Antonio’s Hill Country over 16 years. High performance isn’t a marketing angle for us — it’s the baseline every project starts from.

What’s Included

Every UrbanLUX build, every time.

These aren’t upgrades. They’re standard.

Aeroseal Duct Sealing

We seal every duct in your home from the inside using Aeroseal technology — eliminating the 20–30% energy loss that leaky ducts cause in standard builds.

Spray Foam Insulation

Closed-cell spray foam creates an air-tight thermal envelope, reducing HVAC load and keeping your home comfortable even on 105°F San Antonio summers.

Energy Recovery Ventilation (ERV)

Fresh air without energy waste. Our ERV systems exchange stale indoor air for fresh outdoor air while recovering 70–80% of the thermal energy — no compromise.

High-Efficiency HVAC

We spec high-SEER variable-speed systems sized precisely for your home — not oversized units that short-cycle and leave you with hot and cold spots.

Low-E Windows & Doors

Double- or triple-pane low-E glass blocks solar heat gain without sacrificing natural light — a critical detail in a South Texas climate.

Smart Home Automation

Lighting, climate, security, and entertainment integrated from day one — not retrofitted later. Every UrbanLUX home is automation-ready.

Advanced Air Filtration

MERV 13+ filtration removes allergens, dust, and fine particles before they enter your living space — especially important during Central Texas cedar season.

Whole-Home Performance Testing

Every home we build gets blower door tested and HVAC commissioned before handoff — not hoped for, verified.
