Why not make your dishwasher green


As we all know, running your dishwasher consumes energy, water, and perhaps most importantly chemicals in order to perform its intended function. As a result why not consider the myriad ways to make your dishwashing experience a greener one. By adhering to the below mentioned ten tips, your dishwasher can and will be more environmentally friendly than hand washing.

1. Go for the full load
Before running the dishwasher, wait until you have a full load (same rule of thumb for the clothes washer). This will help make the most of the energy, water, and detergent the machine uses.

2. Choose your washer wisely
Choose a dishwasher that is rated for energy and water efficiency. In the U.S., you can start by looking for Energy Star rated appliances, which use 25% less energy than the mandated minimum. Also, know how to read the yellow EnergyGuide sticker you’ll find on all new dishwashers--as well as other appliances.

3. Join the clean plate club
Go for dishwashing liquid and powder that is natural, biodegradable, and free of petroleum and phosphates. Also look for products sold in bulk to save on packaging. Powdered detergents are lighter and so require less energy to ship. If you are running into spotting problems using phosphate-free detergents, try using a natural residue eliminator like Wave Jet.

4. Skip the pre-rinse
Most dishwashers today are powerful enough to get the all the gunk off, so a lot of pre-rinsing by hand is often just a waste of water and time. Plus, if you rinse all of the dirt off, your dog will have nothing to lick while you’re throwing those plates in.

5. Turn down the heat
Most modern dishwashers have booster heaters to heat the water that comes from your home’s water tank. Seems pretty redundant, right? Turning the water tank’s thermostat down to 120 degrees results in additional energy savings without compromising on cleanliness.

6. Air dry
Instead of letting your washer use electric heat or a fan to dry the dishes, just open the door at the end of the washing cycle and let them air dry. Leave the dishes to dry overnight and they’ll be ready for you when you wake up.

7. Pick the right size
Choose the size model that fits your needs. A compact model is more efficient than a large one unless you have to run it several times a day. For a single person, this might be just right.

8. One glass fewer
Using fewer dishes and utensils over the course of the day means doing fewer loads in the dishwasher, saving energy, water, and detergent.

9. Keep those large appliances away from each other
Putting your dishwasher next to your refrigerator will make the fridge have to work harder due to the heat coming off the washer.

10. Wash off-peak
Delay the start of your dishwasher for off-peak utility hours (some units have timers that will start the cycle at a programmed time). Some utilities even offer reduced rates for energy used during this period, and this is likely to become more and more common in the U.S.

Scientists promote "Global Cooling" with white roofs and cool pavements


California scientists today announced a formula to calculate how much carbon dioxide (CO2) can be offset by increasing the reflectivity of urban surfaces like rooftops. The news was announced at the California Energy Commission's Fifth Annual Climate Change Research Conference.

"White roofs can cut a building's energy use by 20 percent and save consumers money," says California Energy Commissioner Art Rosenfeld. "The potential energy savings in the U.S. is in excess of $1 billion annually. Additionally, by conserving electricity we are emitting less CO2 from power plants," Rosenfeld added. In a study to be published in the scientific journal Climatic Change, it is estimated that replacing non-reflective, dark roofing materials with white ones on an average house with 1,000 square feet of roof would result in an equivalent CO2 offset of 10 metric tons annually.

Scientists have known for centuries that putting white roofs on homes and buildings is a simple and effective way to reflect the sun's powerful rays. Similarly, cool-colored pavements aid in the reduction of "urban heat islands." When rooftops and pavements are more reflective, global warming can be reduced.

Since 2005, commercial buildings with flat roofs in California have been required to have white roofs. Residential sloped roofs are also becoming more efficient. Beginning in 2009, new residential roofs and retrofit constructions in California will be required to have "cool-colored" roofs which reflect a higher fraction of the sun's rays than current roofing materials of the same color.

Because white roofs act as a geo-engineering technique to cool the earth on a global scale, Akbari, Menon, and Rosenfeld propose an international campaign to organize 100 of the world's largest cities in tropical and temperate zones to develop programs to require white roofs and "cool pavements" when roofs are initially constructed and pavements installed.

"This idea of a 'cool cities' campaign could lead to significant energy savings, improved air quality, reduce the heat island effect in summer, and more importantly, cool the globe," says Hashem Akbari. "This simple and effective idea can organize the world into taking measured steps to mitigate global warming. Our findings will help city leaders and urban planners quantify the amount of CO2 they can offset using white roofs and cool pavements."

Water Efficiency


Water efficiency can be defined as the accomplishment of a function, task, process, or result with the minimal amount of water feasible. It should be noted that there is a difference between water conservation and water efficiency. Water efficiency differs from water conservation in that it focuses on reducing waste. A proposition is that the key for efficiency is reducing waste, not restricting use. It also emphasizes the influence consumers can have in water efficiency by making small behavioral changes to reduce water wastage and by choosing more water efficient products.

According to Waterwise (http://www.waterwise.com), here are some simple ways to be more water efficient at home:

• Turning off the tap while brushing teeth- a running tap can waste over six liters per minute.
• Putting a "hippo" or other displacement device into the toilet cistern.
• Fixing dripping taps - a dripping tap wastes thousands of litres of water a year.
• Using a full load in the dishwasher and washing machine. A person should be sure to buy an Energy Star, water efficient model when thinking of buying a new machine.
• Having a short shower instead of a bath.
• Washing fruits and vegetables in a bowl rather than under a running tap. Using the leftover water to feed houseplants.
• Using a watering can or a hosepipe with a trigger nozzle instead of a sprinkler.
• Using a bucket and sponge when washing the car rather than a running hosepipe.

Energy Efficiency


In its most basic form, energy efficiency is using less energy to provide the same level of energy service. Efficient energy use is achieved primarily by means of a more efficient technology or process rather than by changes in individual behavior. That being said, the following strategies contribute to the goal of becoming more energy efficient:

• Passive design strategies can dramatically affect building energy performance. These measures include building shape and orientation, passive solar design, and the use of natural lighting.
• Develop strategies to provide natural lighting. Studies have shown that it has a positive impact on productivity and well being.
• Install high-efficiency lighting systems with advanced lighting controls. Include motion sensors tied to dimmable lighting controls. Task lighting reduces general overhead light levels.
• Use a properly sized and energy-efficient heat/cooling system in conjunction with a thermally efficient building shell. Maximize light colors for roofing and wall finish materials; install high R-value wall and ceiling insulation; and use minimal glass on east and west exposures.
• Minimize the electric loads from lighting, equipment, and appliances.
• Consider alternative energy sources such as photovoltaics and fuel cells that are now available in new products and applications. Renewable energy sources provide a great symbol of emerging technologies for the future.
• Computer modeling is an extremely useful tool in optimizing design of electrical and mechanical systems and the building shell.

Resource Efficiency


The concept of sustainable building incorporates and integrates a variety of strategies during the design, construction and operation of building projects. And while all aspects of sustainable building are important, perhaps none is more important than resource efficiency which can be accomplished by utilizing materials that meet the following criteria:

Recycled Content: Products with identifiable recycled content, including postindustrial content with a preference for post-consumer content.
Natural, plentiful or renewable: Materials harvested from sustainably managed sources and preferably have an independent certification (e.g., certified wood) and are certified by an independent third party.
Resource efficient manufacturing process: Products manufactured with resource-efficient processes including reducing energy consumption, minimizing waste (recycled, recyclable and or source reduced product packaging), and reducing greenhouse gases.
Locally available: Building materials, components, and systems found locally or regionally saving energy and resources in transportation to the project site.
Salvaged, refurbished, or remanufactured: Includes saving a material from disposal and renovating, repairing, restoring, or generally improving the appearance, performance, quality, functionality, or value of a product.
Reusable or recyclable: Select materials that can be easily dismantled and reused or recycled at the end of their useful life.
Recycled or recyclable product packaging: Products enclosed in recycled content or recyclable packaging.
Durable: Materials that are longer lasting or are comparable to conventional products with long life expectancies.

Certifiably green


As an environmentally conscious homeowner, you know how important it is to buy green. That being said, do you ever wonder just how green the companies and products they represent are? Fortunately, a number of different programs are available that have certified products to give them the all-important, official green stamp of approval. Below are four that should be beneficial to you.

Green Seal
Founded in 1989, Green Seal provides science-based environmental certification standards that are credible, transparent, and essential in an increasingly educated and competitive marketplace. Their industry knowledge and standards help manufacturers, purchasers, and end users alike make responsible choices that positively impact business behavior and improve quality of life. (http://greenseal.org)

Cradle to Cradle
Cradle to Cradle Certification provides a company with a means to tangibly, credibly measure achievement in environmentally-intelligent design and helps customers purchase and specify products that are pursuing a broader definition of quality.
This means using environmentally safe and healthy materials; design for material reutilization, such as recycling or composting; the use of renewable energy and energy efficiency; efficient use of water, and maximum water quality associated with production; and instituting strategies for social responsibility.

If a candidate product achieves the necessary criteria, it is certified as a Silver, Gold or Platinum product or as a Technical/Biological Nutrient (available for homogeneous materials or less complex products), and can be branded as Cradle to Cradle. (http://c2ccertified.com)


Scientific Certification Systems
SCS is a leading third-party provider of certification, auditing and testing services, and standards, founded in 1984, whose goal is to recognize the highest levels of performance in food safety and quality, environmental protection and social responsibility in the private and public sectors, and to stimulate continuous improvement in sustainable development.

Wells Fargo offers solar home program in California


Wells Fargo Home Mortgage said today it is one of the first mortgage lenders in California to market a new construction solar home program. Wells Fargo will let home builders pass the state's solar rebate directly to buyers at loan closing to use with their down payment or as a permanent interest-rate buy down to lower monthly payments. In the past, builders would simply reduce the price of a house by the amount of the state rebate offered by the California Energy Commission's New Solar Home Partnership and other utility solar rebate programs.

The solar home program is available on conforming and non-conforming loans for single-family, primary residences, including detached homes and condominiums. The amount of the rebate is tied to the size of the solar energy system built into the new home. As part of its million solar roofs initiative, California announced a target that 50 percent of all new houses built in the state over the next decade will be solar homes. The increasing cost of power and environmental concerns are driving consumer demand for environmentally friendly products. Homeowners in California have been known to save up to 60 percent on their utility bills in a new, energy-efficient solar home.

“Our new solar home offering is part of our larger strategy to support business opportunities that help address climate change, increase energy and resource efficiency and spur a transition toward a sustainable energy economy," said Mary Wenzel, Wells Fargo head of Environmental Affairs. "Through our investments and products, we are proud to support an increasing number of customers who want to take advantage of clean, renewable energy and California's goal to have one million solar roofs in the state by 2018."

"Wells Fargo lives by its corporate pledge to support green development and energy-efficient loan products," said Stuart Tyrie, national program manager for Wells Fargo's National Builder Division. "Our solar home program adds to this environmental commitment. California, which is already the nation's top state for solar homes, has mandated builders offer solar as an option by 2011. Wells Fargo is underscoring its ongoing environmental commitment with a loan program that benefits buyers who purchase new homes with solar units."

Good work practices during remodeling

Regardless of what part of the house your remodeling project takes place in, there are good work practices that you can use to help minimize or prevent indoor air and other indoor environmental problems. These practices include the following:

1. Correct the underlying cause of any problem.
For example, if you are repairing a damaged paint surface, look to see what might have caused the damage, e.g., moisture from the inside (such as condensation), or from the outside (as with roof leaks), rubbing or impact of painted surfaces, or structural damage.

2. Assume Paint in Homes Built Before 1978 Contains Lead.
Unless a lead-based paint inspection shows otherwise, you should treat paint in homes built before 1978 as if contains lead. Exposing anyone to lead dust, especially children, is harmful. See further information on lead if this applies to your home.

3. Do Not Disturb Asbestos
If a project requires disturbing areas that contain asbestos, use an asbestos professional or contact your health department for advice before proceeding. For more information about asbestos, including how to protect those in your home during a remodeling project, read EPA's Asbestos in the Home: A Homeowner's Guide

4. Avoid Exposure to Mold or Bacteria
Potential health effects and symptoms associated with mold exposure include allergic reactions, asthma, and other respiratory complaints. The key to mold control is moisture control. It is important to dry damaged areas and items within 24-48 hours to prevent mold growth. If mold is a problem in your home, clean up the mold and get rid of the excess water or moisture. Fix leaky plumbing or other sources of water. Wash mold off hard surfaces with detergent and water, and dry completely. Absorbent materials (such as ceiling tiles and carpet) that become moldy may have to be replaced. More information is available on EPA's mold page - www.epa.gov/mold

5. Avoid Creating Dust (and Contain Dust That Can't Be Avoided)
Many remodeling activities, from demolition to removing wood casings, have the potential to create dust. Use low-dust work practices (for example, mist surfaces with water before sanding or scraping). Cover the area under work with a durable protective sheeting (e.g., a plastic or poly tarp). Use barriers to keep dust contained to immediate work area. (See also ventilation strategies discussed below.)

6. Provide Ventilation
Exhaust ventilation (e.g., a fan blowing out) from the work area will help remove dust and other pollutants AND, by creating a pressure barrier, will help keep pollutants from spreading to other parts of the house. After applying paints or finishes, installing flooring (such as carpeting), or other activities likely to "off-gas" pollutants, continue to provide maximum ventilation to the space. The typical recommendation is to provide maximum ventilation both during installation and for at least 72 hours after installation is completed.

7. Protect Occupants from Exposure to Odors and Pollutants
Keep occupants, especially children, away from the work area. Clean up the work site before they return. (Workers should wear proper protection, keep clean, and avoid taking dust home with them!) Use barriers (e.g., taped plastic sheeting over doors and other openings) and local exhaust ventilation to prevent pollutants from spreading through the home. When possible, allow materials containing VOCs to off-gas outside before bringing them into the home. Likewise, when possible, apply finishes such as paint and sealers to building materials outside, and bring them into the home after they are dry.

8. Use Appropriate Storage and Disposal Practices for Paints, Solvents, Clean-up Materials, and Asbestos-Containing Materials
Seal containers carefully after use. Keep paint containers in storage areas, preferably equipped with exhaust ventilation, but not near heating, ventilation, or air-conditioning equipment rooms. Use an appropriate waste disposal method to dispose of any paints containing lead or mercury. Follow appropriate regulations for disposal of asbestos-containing materials.

9. Follow Manufacturers' Instructions
As a minimum, follow the manufacturers' recommendations regarding proper use, ventilation requirements, and other health and safety guidelines for all products and materials, including paints, sealants, adhesives, and appliances.

Types of Non-Toxic Paints and Finishes

The term "non-toxic" is used here in its broadest sense. With paints and finishes, it's more a matter of degree. Even Zero-VOC formulations contain some small amounts of toxins. Here are three general categories of non-toxic (or low-toxic) paints: Natural Paints, Zero VOC, and Low VOC

Natural Paints and Finishes - These are paints made from natural raw ingredients such as water, plant oils and resins, plant dyes and essential oils; natural minerals such as clay, chalk and talcum; milk casein, natural latex, bees' wax, earth and mineral dyes. Water-based natural paints give off almost no smell. The oil-based natural paints usually have a pleasant fragrance of citrus or essential oils. Allergies and sensitivities to these paints is uncommon. These paints are the safest for your health and for the environment.

Green Planet Paints - natural clay paints for interiors using unique Mayan clay pigments. (www.greenplanetpaints.com)

Zero VOC - Any paint with VOC's in the range of 5 grams/litre or less can be called "Zero VOC", according to the EPA Reference Test Method 24. Some manufacturers may claim "Zero-VOC's", but these paints may still use colorants, biocides and fungicides with some VOC's. Adding a color tint usually brings the VOC level up to 10 grams/liter, which is still quite low.

Homestead Paints - Zero-VOC, flat and low-sheen interior paints. (homesteadhouse.ca)

Low VOC - Low VOC paints, stains and varnishes use water as a carrier instead of petroleum-based solvents. As such, the levels of harmful emissions are lower than solvent-borne surface coatings. These certified coatings also contain no, or very low levels, of heavy metals and formaldehyde. The amount of VOC's varies among different "low-VOC" products, and is listed on the paint can or MSDS. Paints and stains, to meet EPA standards. must not contain VOCs in excess of 200 grams per litre. Varnishes must not contain VOCs in excess of 300 grams per liter. As a general rule, low VOC paints marketed by reputable paint manufacturers usually meet the 50 g/L VOC threshold. Paints with the Green Seal Standard (GS-11) mark are certified lower than 50 g/L (for flat sheen) or 150 g/L (for non-flat sheen). Low VOC paints will still emit an odor until dry. If you are particularly sensitive, make sure the paint you buy contains fewer than 25 grams/liter of VOC's.

Radiant Heating


Radiant heating systems involve supplying heat directly to the floor or to panels in the wall or ceiling of a house. The systems depend largely on radiant heat transfer: the delivery of heat directly from the hot surface to the people and objects in the room via the radiation of heat, which is also called infrared radiation. Radiant heating is the effect you feel when you can feel the warmth of a hot stovetop element from across the room. When radiant heating is located in the floor, it is often called radiant floor heating or simply floor heating.

Radiant heating has a number of advantages: it is more efficient than baseboard heating and usually more efficient than forced-air heating because no energy is lost through ducts. The lack of moving air can also be advantageous to people with severe allergies. Hydronic (liquid-based) systems use little electricity, a benefit for homes off the power grid or in areas with high electricity prices. The hydronic systems can also be heated with a wide variety of energy sources, including standard gas- or oil-fired boilers, wood-fired boilers, solar water heaters, or some combination of these heat sources.

Despite their name, radiant floor heating systems also depend heavily on convection, the natural circulation of heat within a room, caused by heat rising from the floor. Radiant floor heating systems are significantly different than the radiant panels used in walls and ceilings. For this reason, the following sections discuss radiant floor heat and radiant panels separately.

Radiant Floor Heat
There are three types of radiant floor heat: radiant air floors (air is the heat-carrying medium); electric radiant floors; and hot water (hydronic) radiant floors. All three types can be further subdivided by the type of installation: those that make use of the large thermal mass of a concrete slab floor or lightweight concrete over a wooden subfloor (these are called "wet installations"); and those in which the installer "sandwiches" the radiant floor tubing between two layers of plywood or attaches the tubing under the finished floor or subfloor ("dry installations").

Types of Radiant Floor Heat

Air-Heated Radiant Floors
Because air cannot hold large amounts of heat, radiant air floors are not cost-effective in residential applications, and are seldom installed. Although they can be combined with solar air heating systems, those systems suffer from the obvious drawback of only being available in the daytime, when heating loads are generally lower. Because of the inefficiency of trying to heat a home with a conventional furnace by pumping air through the floors, the benefits of using solar heat during the day are outweighed by the disadvantages of using the conventional system at night. Although some early solar air heating systems used rocks as a heat-storage medium, this approach is not recommended. For further information, see the section on solar air heating systems.

Electric Radiant Floors
Electric radiant floors typically consist of electric cables built into the floor. Systems that feature mats of electrically conductive plastic are also available, and are mounted onto the subfloor below a floor covering such as tile. Because of the relatively high cost of electricity, electric radiant floors are usually only cost-effective if they include a significant thermal mass, such as a thick concrete floor, and your electric utility company offers time-of-use rates. Time-of-use rates allow you to "charge" the concrete floor with heat during off-peak hours (approximately 9 p.m. to 6 a.m.). If the floor's thermal mass is large enough, the heat stored in it will keep the house comfortable for eight to ten hours, without any further electrical input (particularly when daytime temperatures are significantly warmer than nighttime temperatures). This saves a considerable number of energy dollars compared to heating at peak electric rates during the day.

Electric radiant floors may also make sense for additions onto homes for which it would be impractical to extend the heating system into the addition. However, homeowners should examine other options, such as mini-split heat pumps, which operate more efficiently and have the advantage of also providing cooling.

Hydronic Radiant Floors
Hydronic (liquid) systems are the most popular and cost-effective radiant heating systems for heating-dominated climates. Hydronic radiant floor systems pump heated water from a boiler through tubing laid in a pattern underneath the floor. In some systems, the temperature in each room is controlled by regulating the flow of hot water through each tubing loop. This is done by a system of zoning valves or pumps and thermostats. The cost of installing a hydronic radiant floor varies by location and also depends on the size of the home, the type of installation, the floor covering, remoteness of the site, and the cost of labor.

Remodeling “Green” can earn you more green when time to sell


It goes without saying that the housing market is in one of the tougher periods experienced in decades, a period not seen since the Great Depression (according to those that draw such comparisons). In fact, experts have predicted that 2008 sales could be down more than 40% from their peak of a few years ago.

The question remains though . . . what if you really need to sell your home right now? What if the need to relocate requires you to sell, or perhaps the desire to buy a bigger home due to an ever-increasing family size? Quite simply, what if you can't afford to wait until the market improves?

The good news is you have the ability to do work on your home that puts you head and shoulders above the other houses for sale in your price range by making smart and quick eco-renovations, i.e. remodeling/renovating/upgrading “green”. In a market such as this one where buyers are looking for added value in their every purchase, making smart green remodeling tweaks invariably makes your home more competitive, not to mention reducing your energy bills, reducing your water waste, improving your indoor air quality, and bettering the fate of the planet.

Here for you now are a handful of ways to make your “green” house stand out from the rest:

Do it yourself projects

• Save Energy—Plant trees to provide necessary shade
• Seal all exterior holes leading in with better caulk
• Repaint using Low-VOC or No-VOC paints
• Replace older, single pane windows with double pane windows
• Add more insulation to walls, ceilings, attic
• Install a water heater timer
• Install a programmable thermostat
• Install a ceiling fan to improve efficiency
• Install energy efficient lighting

Projects requiring a contractor
• Install new green flooring; be it natural fiber carpet, cork, bamboo, sustainable or reclaimed wood
• Install energy recovery ventilators
• Install a tankless water heaters
• Retrofit radiant heat
• Have an energy audit and thermographic inspection
• Install a whole house fan

Obviously there are assorted other green remodeling tips one could take on with the simple concept in mind that any of the above will invariably increase your home’s value and make those living in your home healthier and happier.
