Roof has been provided with a white TPO (thermoplastic polyolefin) roof which is the most reflective roofing type available. This highly reflective roofing type helps to keep the house cool. Furthermore, compared to asphalt based built-up-roofing, this single membrane TPO roof does not leach out harmful chemicals which are detrimental to the environment and people's health.
Insulation at 6339 Contra Costa has a higher R value in just about every location. This combined with a third-party inspection of the insulation installation will result in a more thermally efficient structure thus reducing heating and cooling demands.
Doors and Windows at 6339 Contra Costa are high performance with very low U and SHGC values. The size and placement of the windows allows for copious amounts of daylight and natural ventilation thus reducing the demand for artificial light and artificial heating and cooling and saving a substantial amount of energy.
Light emitting diodes (LED) lighting has been used to provide lighting throughout the home in both the indoor and outdoor lighting fixtures. LEDs offer the same lighting values of a 60 watt incandescent at only 6-8 watts offering huge energy savings and extended life times. On average, every LED bulb will save 1,530 kWh and $151 dollars in electricity and replacement costs over its lifetime (50,000 hours). Not only do LEDs save you money, but they also come in a variety of light qualities allowing for perfect lighting for every room.
The landscaping uses drip irrigation provided by the cisterns, using rainwater conserved during the rainy season. The plants were selected both for their beauty and their ability to withstand drought, ensuring you can enjoy your beautiful yard even during dry years.
6339 Contra Costa has two cisterns which capture and recirculate rainwater. They can hold over 3,000 gallons of water. Assuming average rainfalls, the cistern will be filled, used, refilled and used again in one-year winter/summer cycle. These 6,000 gallons of rain water can be used for irrigation, the waterfall and the fountain. A plant will require about three gallons of water per week to survive, and a tree about ten gallons of water. Plants will need to be watered about 24 weeks of the year to survive. So the cistern should be able to serve 83 plants per year, or 25 trees without drawing on domestic water supply. The waterfall and reflecting pool will also use the captured and recirculated rain water.
6339 Contra Costa has one of the most efficient types of heating system which is radiant floor heating, with a radiant barrier between the ground and the foundation slab to minimize loss downward toward the soil. Hydronic (liquid) systems are the most popular and cost-effective radiant heating systems. Hydronic radiant floor systems pump heated water from a boiler through tubing laid in a pattern under the floor.
6339 Contra Costa has been stubbed out for solar power of the owner's choice. Energy Savings would depend on the type of solar panel system the owner chooses. For Solar Electric (PV) System: 6.03 kW DC (5.909 kW AC) producing 8,822 kWh/ below is the quote and electricity saving analysis received from a solar Vendor.
Anticipate savings of approximately $2,663 in electric bills (90%) at current utility rates in the first year. These savings will grow as electric utility rates rise. The purchase of electric energy (kWh) from your utility is expected to be reduced by 88%. Your electric rate has Time-of-Use attributes, and this project will reduce average utility electric cost from $0.30 to $0.26 per kWh. Over 25 years, annual utility savings should average $4,597, for a total utility savings of $114,937. After tax effects are applied, savings average $2,759 annually or $68,963 over the system life.
The home is equipped with smart light switches and the Nest thermostat, allowing you to control your home energy use intelligently and efficiently.

The garage has been pre-wired for Type II electric vehicle charging stations. Type II chargers are those used by the current generation of electric vehicles including Tesla, Toyota, and Chevrolet. Pre-wiring of 240 volt wires and conduit allows owners to cost effectively install the charger required for their electric vehicle of choice. Full electric vehicles produce less than half of the greenhouse gas emissions over their lifetime compared to a traditional combustion vehicle.
