Touchless Faucets for the Home?

FaucetSeemingly relegated to airport and stadium bathrooms, touchless faucets are starting to make their way into homes, with plumbing manufacturers moving to offer more design options.  It’s an idea that may seem strange at first, but touchless faucets are actually quite practical, especially for a children’s bathroom.  They are clearly beneficial in that they limit the spread of bacteria, but they also save water.  Consider how much water is wasted while brushing teeth.  A touchless faucet ensures that water isn’t running the entire time someone is brushing.  Combined with a water-saving aerator, touchless faucets can save a substantial amount of water.  And, since the water is set at a specific temperature, having a touchless faucet removes the risk of a child scalding him or herself accidentally. 

Touchless faucets are also available for kitchens, though consumers will need to do some research to make sure they are getting something that fits their habits.  Kitchen touchless faucets clearly carry the same health and water conservation benefits but most are set at one temperature, which might be inconvenient.  Also, if the faucet does not have an override switch, the homeowner will have to hold his or her hand over the sensor while filling a pot or doing dishes, though perhaps running water while doing dishes is a habit we should reconsider.

Low Impact Living: Green Your Kitchen

Editor’s note: Thinking about a kitchen remodel? This week, Low Impact Living takes a look at every element of kitchen use, and how you can both make the space more efficient, more livable, and more earth-friendly. This post was originally published on September 7, 2007.

You may not know it, but your kitchen is one of the biggest resource hogs in your house. You use electricity and natural gas for your appliances. You use water in your sink and dish washer. Your fridge is stocked with foods grown and transported from all over the world that require chemicals, water and fuel to be produced and transported. And then there’s the non-recyclable packaging that goes straight to a landfill.

Here is a list of things you can do in your kitchen to lower your environmental impact, and also to live in a healthier home. We have recommendations for appliances, products and new behaviors.

Any chance you are planning a kitchen remodel? We also have great recommendations for you– wonderful new materials for countertops,cabinets and floors, leads on top-rated green architects and interior designers, and more. Just scroll down if you’re focused on a remodel.

Get Green in the Kitchen

1. Use energy-saving appliances. You can greatly reduce your power and water usage and your greenhouse gas production by using Energy Star appliances. Energy Star appliances can save as much as 50% of your energy and water use, and can cut your carbon footprint by 1000+ pounds, compared to standard appliances. Click here to see Energy Star models.

2. Use compact fluorescent lighting. Compact fluorescent lights use 1/4 the energy and last up to 10 times as long as standard bulbs. And they come in versions that are dimmable, recessed-ready, and daylight spectrum–any version of light type you can think of. Each high-use bulb you replace will save up to $10 and 100 pounds of carbon dioxide per year, and they last for many years. Click here to see our wide range of CF lighting options.

3. Recycle and Re-use. Can you rinse that ziplock and use it again? Can you reuse the containers you got from take-out? And don’t get plastic bags every time you go to the store for groceries– take durable reusable sacks with you. Click here for reusable grocery bags..

Heating Your Home: Heat 101

FlamesAuthor’s note: The following article on home heating is the second in an eight-part series.

What is Heat Exactly?
If we’re going to talk about better ways to heat a home, we’d better have some idea of what heat is. What you experience as heat is just the energization of the molecules in your body. Heat is the energy that gives those molecules kinetic (vibratory) energy.

Obviously, your body produces its own heat through the metabolic process (burning calories); the important thing is that your environment neither inundates you with excess energy (when it’s too warm), or draws too much energy away from you (when it’s too cold). This begs the question, how does your environment give or take energy from you? Read the rest of this entry »

Heating Your Home: Radiant Heat, Wood Heat

Tempcast Large Stone HeaterAuthor’s note: the following article on home heating is the first in an eight-part series. The series specifically targets climate found in the San Francisco Bay Area, but has applicability elsewhere.

According to the U.S. Department of Energy, heating and cooling amounts to 46% of all energy consumed by our homes. Water heating uses another 14%. In coastal California, where extreme heat is rare and winters are mild, a properly sited, well designed passive solar home can generate its own heat and hot water, and do without air conditioning.

Historically, few homes are so well sited or built. Since our area has more heating days than cooling days, most homeowners need a heating system. What few know is that many indoor air quality problems can be by-products of forced air heating, ventilation and air-conditioning (HVAC) systems installed in their homes.

First LEED Certified MedSpa

Relaxation!
Fashion!
Celebrity!
Botox!
Booze!
Interiors!
Green!

Yes, most of this list refers to the Brit series Ab Fab but if Eddy and Patsy turned in their smokes and cocktails for organic and sustainable munchies then they too would be excited for the opening of the Epi Center MedSpa, the first LEED certified MedSpa in the country. (Another LEED spa exists in D.C. but it isn’t a MedSpa). So, because fictional characters from a long ago Brit TV series couldn’t check out this just opened San Fran based spa, I decided that I had to do it. Read the rest of this entry »

It’s Time to Rethink Tub Sizes

BathtubAs I mentioned in my KBIS Report, I was struck by the sizes of bathtubs on display at this year’s kitchen and bath trade show. Though green was king thoughout most of the convention, companies that pitch themselves as catering to a luxury market seem to be sending the message that if you have enough money to waste water in giant bathtubs, then they’d be happy to sell you some, as if money absolves you of any kind of environmental responsibility.

It’s a hard statistic to nail down, but a person uses between fifty and seventy gallons of water each time he or she takes a bath. This number includes water wasted waiting for the desired temperature as well as hot water used to return the cooling water to the desired temperature. Compare that number to a five minute shower, which uses around twenty five gallons of water, possibly half that if the shower uses a flow restrictor. Clearly, if water conservation is the main goal, a quick shower is the answer, but let’s not throw out the bathtub with the bathwater just yet. Read the rest of this entry »

Low Impact Living: The Low Down on Tankless Hot Water Heaters

tanklesshotwaterheater.jpgEditor’s note: As part of our new content partnership with Low Impact Living, we’ll be bringing you tips and tricks from their massive and growing archive of products and projects that can help you save energy, water and money around the house. Today, LIL blogger Jason Pelletier takes a look at tankless hot water heaters. This post was originally published on Monday, April 28, 2008.

Tankless hot water heaters are becoming a must-have appliance in homes these days. They purport to offer many benefits - instant and endless hot water, less wasted space, and a smaller carbon footprint as well. They can even be used to power radiant underfloor heating that is a luxury found in many green homes.

But are they truly the best option? What can you expect from one, and what do you have to worry about with installation? Finally, are there other options available that offer the same benefits without some of the challenges? We’ll try to cover most of that in this piece.

Elements of Building: Materials

wood constructionAt the heart of all building projects are the materials, the stuff, the bricks and sticks, the elements that are assembled to build a building. Different materials have different impacts on the Earth. Some require extensive resources for their manufacture. Steel and other metals need to be refined from ore and processed into their final forms, often several operations, all taking great amounts of energy. The choices that go into selecting building materials have long range ramifications in a number of ways.

The materials we use in our buildings have an enormous impact on the Earth. Choosing materials with a lower impact can be an important criterion, but the matter needs to be looked at with proper long-term perspective. Careful use of materials with a long useful life (rather than materials which merely stick around for a long time after they have reached the end of their useful life, like vinyl siding) can result in a building that serves generations. Densities of use found in modern cities are only realistically possible when using higher impact materials such as steel. However, the offsetting benefits coming from the use of those materials helps to make this a more reasonable choice.

Elements of Building: Water

tapwater3.jpgIn the United States, 340 billion gallons of fresh water — or 1/4 of the nation’s total supply — are pulled from rivers and reservoirs every day. (See greenerbuildings.com)

Our taps, plumbing fixtures, and irrigation systems all draw from the same sources of clean, potable water. After being used, most of the water ends up in the sewer system — all of it, at that point, contaminated. Then it is treated and returned to a body of water. This creates a cycle in which unnecessarily large volumes of water circulate through the built environment and municipal treatment facilities. However, in the last decade or so, major strides have been made in reducing the amount of water that must go through such a cycle. Read the rest of this entry »

Lettuce Eat Green

mixt-greens3.jpgRestaurants here in San Francisco open, and close, almost as often as the fog rolls in so we don’t usually pay an extreme amount of our precious attention to another restaurant du jour. Mixt Greens recently opened but they don’t qualify for new kid on the block status nonetheless they do deserve green props. Thus I direct my attention to their third installment of the Mixt Greens empire.

This third location, located in SoMa, just opened and used zero-VOC paints to improve the air quality, and I could definitely smell the food and not the fumes. They even used recycled paint to cover their ceiling. I didn’t find any bamboo or cork for the flooring but something better as they used an unfinished concrete floor with 50% flyash content. That high flyash content along with the fact that the floor will last a long time (plus it’s easy to clean) makes that choice a no-brainer. Read the rest of this entry »
