Shelter-In-Place and Safe Room Design Consulting 
Whether it is an overwhelming storm, a new strain of H1N1 flue, a man made act against a population center, or a home invasion, uncertainty is the new certainty.
Hurricane's Katrina created 1.2 million refugees. Rita shut down most of the Texas highway system. What's next? We can wait for a panic evacuation, or we can address uncertainty with 'shelter-in-place' planning.
The availability of energy is a key to a successful civilization.  It also remains a key to a successful shelter-in-place dwelling design.
Safe Room
A safe room or panic room is a fortified room installed in a residence to provide a safe shelter in the event of a break-in, hurricane, or other threat.   ECO structurally designs residential safe-rooms in closet, pantry, or bathroom spaces using normal construction materials and techniques, plus special accessories like 'Devil-Door' framing plates.
A basic Safe Room will use an exterior-grade solid-core door framed and installed to resist battering. Walls and ceilings are reinforced. Walls and doors may be further reinforced with steel or other materials. Safe rooms can have independent ventilation systems and a separate means of communication.
Safe Room within Shelter-In-Place
ECO can provide a Safe Room within customized Shelter-In-Place consulting with permit ready blue prints for residential and commercial projects.  


Electrical Power for Shelter-In-Place

Ceiling Fan                     120

Table Fan                       150

Freezer (stand-alone)           600

Lights CF                        25

Microwave oven                  925

Window Air conditioner         1000 

(~5000 BTU/1000 Watts (Frigidaire FAA067P7A ,  GE ASM05LK, or equal)


Generator                 2500 to 5000 Watts(Craftsman 30250 - 2500 Watts; or a Briggs & Stratton EM7 - 5000 Watts)


Electrical Power for Shelter-In-Place


A 3000 Watt Solar PhotoVoltaic Array can provide 3,976 kWh/year at a net cost $16,800. But solar PV only works in peak daylight hours, so plan to add a generator such as a Craftsman 30250  (2,500 Watts) or a Briggs&Stratton EM7  (5000 Watts).
For whole home or for small commercial facility standy power a larger natural gas power generator like a Generac QT03624ANAX NG fueled 36 kW (36,000 Watts) may be a good solution. 

Remember that all generators must be located outside and away from windows, vents, basements or crawl space area to avoid fumes or exhaust.


A good facility or small community on-site power choice is a Capstone 65 kW NG fueled microturbine generator which provides clean emissions continuous power for critical service facilities.
