The Cave House Philosophy
The Cave House is not a vacation rental. This information is for guests of John and Mary.
The Cave House at Kula Kai is very energy efficient, comfortable,
and easy to maintain home. The sturdy construction is safe for the occupants
and the environment.
The Cave House was designed to provide a comfortable and secure place to live, yet be very energy efficient and environmentally friendly. If you are considering building your own house in Hawaii and want to do a short visit in another energy-efficient home, the Cave House is a good place to see if you like it.
Indoor Temperature Control
The Cave House is properly insulating and designed to be very comfortable without any heating and air conditioning systems. Opening some windows during the day to take advantage of the ocean breeze may be helpful, and closing all windows in the late afternoon will be best for retaining the day time warmth throughout the night. So far, the minimum overnight indoor temperature has been 69 or 70 degrees Fahrenheit. If you are considering building or buying a house in Hawaii and are not convinced that central heating and air-conditioning are not necessary with proper insulation, then a stay at the Cave House will provide a firsthand confirmation of the benefits of good design of energy-consuming heating and cooling. The house is at about 1700 feet elevation above sea level, which makes the seasonal average temperature outside about 70 to 77 degrees. The average day to night outside temperature change is about 15 degrees.
Solar Hot Water Heating With
Electric Backup
The Cave House has two solar hot water systems with electric backup for hot water. Depending upon how much direct sunlight hits the rooftop solar collector, the minimum early evening water temperature is 78 to 85 degrees. On cloudy days when the water temperature may fall below 83 degrees, you can turn on the manual switch which is next to the water heater. Within an hour, the 120-gallon tank will have enough hot water for many showers.
Laundry
The two washing machines provide adequate washing capacity. The dryer is also a large capacity front loading machine. If one is trying to save energy, the clothesline beside the house, helps reduce energy consumption.
Kitchen appliances
A smooth top stove, large refrigerator with bottom freezer, dishwasher, disposal, and microwave are all modern and energy-efficient.
Catchment and Reverse Osmosis
Pure Drinking Water
The Ka’u desert averages about 15 inches of rain a year and has no permanent surface streams. There is no public sewer and water utility in the Ka’u District. All appliances and toilets in the Cave House are water energy efficient. A reverse osmosis water filtration system in the kitchen supplies pure drinking water. The large 20,000-gallon water tank and catchment system has all the design features to keep the water safe and clean. Two 10,000-reserve tanks are on the farm. It is treated with chlorine as needed. We recommend this water for all drinking water. Reverse osmosis is the most effective filtration system available.
Reduced Allergens
The smoking of any substance is prohibited in the Cave House and on the grounds, as is the use or possession of any illegal substances.
Energy
The Cave House has rooftop solar electric connected to the grid.
Steel Houses Save Lives and Property from catastrophic events
Steel houses such as the Cave House are resistant fires, big earthquakes, and extremely high winds, thus reducing the loss life and property damage from catastrophic events, Steel houses do not require poisonous chemical treatments to protect against termites, saving the environment from more harmful chemicals.
Appearance
On the outside, The Cave House looks like a Parker Ranch house, one of the common designs in Hawaii made famous by its use at the Parker Ranch. On the inside, the walls are all drywall, and the only sign of its stronger construction can be seen in a few places along the vaulted ceiling.
House positioning and
location
The southern part of Hawaii has steady winds; this is very good for windmills, but sometimes uncomfortable for people. The 1907 lava flow created a natural wind barrier in the form of an a’a lava ridge to the west of the Cave House, making outdoors a little more comfortable by reducing the force of the wind to a modest breeze.
Kula Kai View Estates
Sub-Division and the Ocean View Community
Kula Kai is a gated community with three-acre residential lots. There is very little traffic on the only main street, Kona Kai Boulevard.
The Cave House is not in the Ocean View sub-division. The Ocean View shopping area serves the five subdivisions of Kula Kai View Estates, Ocean View, Ranchos, Kula Kai Gardens, and Kahuku Country. It has a few restaurants, grocery stores, and two small shopping areas. The restaurants are not fancy. The Ocean View area is an Hawaiian version of small-town America.
