Make Your Existing or Future Home a Greener Place to Live

THE RIGHT SITE

• A site with smart landscaping is important to help make your home comfortable, affordable and attractive.
• Water-efficient bermuda or buffalo grass is planted in sunny areas.
• Plants, shrubs and trees that grow successfully in Northern California.
• Gutters and downspouts direct water away from house.
• An irrigation system conserves water by using devices such as manual flow-control valves, a rain shut-off, and a timer with multiple start times.

THE RIGHT DESIGN

• Comfort and economy is possible when a house is designed for its site and climate.
• Minimal Solar Heat Gain:
• Longest walls face north and south.
• Most windows face north and south.
• Most windows are shaded on the outside by overhangs, covered porches, awnings, trees, trellises, or pergolas.
• Garage and least-used rooms are positioned on west side as buffers from the west sun.
• Maximum Ventilation:
• Most windows are operable and positioned for cross breezes.
• Most rooms have windows on two walls.
• High, centrally-located, operable windows enable hot air to move up and vent to the outside.

THE RIGHT EXTERIOR

Cool Shell and Attic:

• Light colored paint, siding, and roofing are used.
• A continuous vent strip runs underneath the roof overhang to let air into the attic.
• Roof ridge has a continuous strip of venting or several passive vents close to the ridge.
• Attic insulation does not block air flow path between roof overhang vents and ridge vents.
• Attic has a radiant barrier below the roof decking or between the rafters (looks like aluminum foil). Radiant barrier is especially effective when ductwork is in the attic.

Minimum Maintenance:

• Exterior wall material is low maintenance (brick, stone, stucco, cement board).
• Roof has forty-year life (metal or tile).
• Decks are made of materials that have at least a 10-year life (not solid wood).

Maximum Insulation:

• Insulation is at least 10 inches deep and evenly distributed
• Wall insulation is a type that fills every nook and cranny, such as wet-blown cellulose.

Optimal Windows:

• Unshaded windows have solar screens or low-e glass (except on the north side).
• Window frames are wood, vinyl or fiberglass.

THE RIGHT INTERIOR

Using the right materials can improve indoor air quality and increase comfort. Choosing energy efficient appliances will save you money.

Healthy Materials:

• Flooring is mostly a hard surface, such as concrete, tile or wood.
• Other flooring materials are natural wool, jute, sea grass, cork or true linoleum.
• No vinyl wallpaper is used in the home.
• Bath has exhaust fan vented to outside.
• Cook top has exhaust fan vented to outside.
• Laundry/utility room has exhaust fan vented to outside.

Efficient Appliances and Lights:

• Water heating has a 10-year warranty.

You can live in a home that is healthier, more comfortable, less expensive and lasts longer—basically, a happier home!  It’s a choice and a smart way to make a positive difference in the world. “Greening” your home  is also a strong selling attribute of homes in Marin.

So, want to do something simple, cheap and incredibly important for our environment?   This bright idea is just hanging around your home–cut your electricity consumption.  If we decrease our electrical usage by 50%, we’ll basically cut our emissions from coal by 50%.

And, where does most of our electricity usage come from? …right in our homes.  Sixty six percent of electricity generated is used for heating, cooling, and lighting buildings.  It’s sobering to think that 1/3 of the world’s population still has no access to electricity, so cutting the US consumption will make a significant difference in decreasing the world’s greenhouse emissions.

First, let’s see how bright your energy knowledge bulb is…

True or False?

1. Most of your washing machine’s energy is used just to heat the water.

2. Your mom was wrong, opening the refrigerator door uses very little of it’s energy usage.

3. Most of the energy of the electricity used to power home electronics is consumed while the products are off.

4. Standard light bulbs produce more heat than light as they did in the past.

5. Solar is not the best energy source for electricity.

WHAT CAN YOU DO?

REFRIGERATOR–GET A NEW ONE

Consider buying a new refrigerator.   In most places in the US, the fridge is the 2nd largest user of electricity, right after air conditioning.  So here in Marin, where air conditioning is often provided free, it’s the first.   With most appliances you save energy by using them less, but you can’t do that very well with your fridge. The main way to save money with this appliance is to use an efficient model. New refrigerators aren’t just a little more efficient, they’re incredibly more efficient. A 1986-era fridge uses 1400 kWh a year, while a post-2001 fridge uses only 500 kWh — a 64% savings.

WASHER–USE COLD WATER, FRONT LOADING

Washing your clothes in hot water instead of cold water for a year, wastes more electricity than leaving the refrigerator door open 24 hours a day for a year! Front-loading washers use 40-75% less water and 30-85% less energy than typical top-loaders.

ENERGY STAR

So, here’s a cool story about California.  Back in 1976 California set a maximum amount of energy (1400 kilowatt hours per year) use for 18 -cubic foot fridges,  over the protests of appliance manufacturers.   After they finished protesting, appliance producers met the standard easily, and on time. Because California represented such a large share of the market, and the necessary improvements were so minimal, the appliance manufacturers applied that standard to their entire lines. California kept demanding more efficiency.  Now, the criteria is 500 kWh….wow!  So, not only are we doing our part by living in a cool state,  we can do even more by picking Energy Star, government rated low kWh usage appliances.

LIGHT BULBS

Compact fluorescent bulbs, or CFLS, use 75 % less energy, last six times longer, generate less heat and reduce energy costs associated with cooling as compared to incandescent bulbs.  Each bulb will save $30 or more in energy cost over its lifetime compared to standard bulbs.

BELIEVE

Let your light shine.  Environmentalist Alex Steffen said, “Optimism is a political act. Those who benefit in the status quo are perfectly happy for us to think nothing is going to get any better.  In fact, these days, cynicism is obedience.”  So, believe each step you take, each bit of electricity you don’t use, will make a difference.  Talking about believing, check out this cool link:

Answers to quiz:   All TRUE….

1. 90% of a washer’s electrical consumption is to heat water.

2. Opening your refrigerator door may be irritating, but it only uses about 2% of it’s normal energy usage.

3. According to the Department of Energy, 75% of the electricity used to power home electronics are consumed while the products are turned off. It’s called a “Phantom Load”. Using power strips and sleep mode elevates this.

4. Incandescent light bulbs still produce more heat than light.

5. The best energy is the one you never use.

The California Real Estate Inspection Association (CREIA) advises homeowners and home sellers to consider a “physical home check up” to ensure that they are fully informed on the current conditions and components of their home. A home that has not been recently inspected may have undiscovered, minor or major maintenance items that could lead to a significant financial expense to correct or even replace if not discovered.

“Seller shall make the property available for all buyer investigations. Seller shall have water, gas, electricity and all operable pilot lights on for Buyer’s investigations and through the date possession is made available to Buyer.” (Excerpt from: Paragraph 9B of the California Association of Realtors® California Residential Purchase Agreement)

Having everything ready for the inspection can prevent unnecessary delays. For liability reasons home inspectors do not move personal belongings. Most home inspectors will charge an additional fee if they must return to the property to inspect item which were not accessible.

The seller should verify that:

• All utilities are on
• Pilot lights are lit (The gas provider will usually light pilots at no cost to the owner)
• Attic access is clear of clothing or stored items
• Crawl space entrances are not blocked or nailed in place
• Water heaters are accessible
• Furnaces are accessible
• Sinks, showers and bathtubs are clear of dishes or personal items
• Built-in appliances are free of stored items and can be operated
• Electrical panels are accessible and not locked (Electrical sub-panels inside the home are often painted and removing the cover will mar the finish. The seller’s agent should ask the seller to grant permission to the inspector to remove the panel cover to look for life/safety issues)
• Areas or items to be inspected are freely accessible
• Pets are secured (Unsecured animals should be removed from the property or secured in an area that will not need to be inspected if the seller (or occupant) will not be present)                                                                                                                                                                                                    Click here for the printable version of Preparing for a Home Inspection Checklist.
