Project: Ojai, California – Radiant Cooling

Architecture: Patrick W. Nolan
Builder: Otis Bradley Company, Inc.
Interior Design: Rhett Judice

In the words of the late great singer – James Brown – I feel good !  Like I know that I should! Ughhh ! Yeahhhh !

Everybody loves radiant heat ! It feels good.  Done right – you don’t even know you have a heating system – it just feeeeeels good!

Our new custom home in Ojai  – is traditionally designed in a French Provincial style, yet includes high tech equipment.  Not only does it have radiant heating tubes embedded in the concrete slabs under the French limestone floors, but … we also have cooling tubes in the ceiling.

This project – although a traditional, French Provincial style home, still has high tech equipment. The house is super insulated using insulated concrete block, ICF, technology and both heated and cooled using radiant panels in the floor and ceiling.

The problem:

Everyone loves radiant floor heat, but in hot climates everyone wants cooling as well.  Typically this means an entire second – usually a ducted forced air system – is added just for cooling.

The solution:

Use radiant to cool as well as heat.

We did this with the help of special panels and control systems that sense humidity and allow us to cool without creating condensation.

Bottom Line:

It feels GOOD ! In hot or cold weather !Everybody loves radiant heat! You won’t even know there is a heating system in a home if its done right – it just feels comfortable.

California Title 24

Title 24 is an energy law that was first established on June 1, 2001.  This energy law was created to conserve the high consumption and demand of energy in California.  The new compliance standards are applicable to both commercial and residential lighting.  Lighting for commercial buildings and residential homes require high efficacy luminaires or dimming controls in each room.  Here are the 2005 CA Residential Lighting Requirements*:

Changes in Brief:

Title 24 will require high efficacy luminaires, occupancy sensors, and/or dimmers in most spaces:

  • Kitchens: At least 50% of the total wattage of kitchen lighting must be from high efficacy luminaires. Non-high efficacy luminaires must be switched separately from high efficacy            luminaires.
  • Bathrooms, utility rooms, garages and laundry rooms: High efficacy lighting or manual-on occupancy sensors required.
  • Exterior, attached to building: High efficacy luminaires or combined photo sensors/occupancy sensors required.
  • All other interior spaces: High efficacy luminaires, occupancy sensors, OR dimmers required.
  • Recessed lighting: When installed in insulated ceilings, must be both Type IC (insulated covered) and airtight (AT) rated.
  • Electronic ballasts: Electronic ballasts are required for all fluorescent luminaires 13 watts or greater. Continue reading “California Title 24”
