Advantages of the Roof Garden
- Reduces urban heat island effects
- Storm water run-off management
- Adds valuable/useable space providing economic benefits
- Energy efficiency year-round
- Air and water purification
Centuries old, the roof garden concept is both functional and aesthetically-appealing. The green roof -- or roof garden technology improves the structure's energy efficiency while adding plant life in populated areas to support health and well being of people and wildlife while also helping clean the air.
The focus on
improving the quality of life in higher density urban environments has made
issues such as cooling the city and air quality more pertinent than ever. Roof Gardens meet the objectives of
many of the mandates to improve the air quality of cities by mitigating
the effects of heat islands caused by ever increasing development.

You've probably noticed the side-loading clothes washers and wondered if they really save energy and water!
Yes, and YES!
Horizontal axis clothes washers cut power by 30% or washing and reduces water use by requiring less in the tub for each load.
You can also reduce dryer energy by 10 to 20% by using the new appliances designed for energy efficiency. Look for the ENERGY STAR label to ensure that you're getting models with the best energy efficiency.
If you have Solar PV cells or a Solar Thermal system...run your wash in the afternoons with solar hot water and solar power!
You can also save energy by hanging your clothes to dry. Indoors. Outdoors....take your choice...they are both zero energy options!
Energy Star Dishwashers
If you're the kind of cook who absolutely refuses to wash your dishes in the sink -- which is far more energy and water efficient than an appliance -- be sure to select the highest efficiency model using Energy Star rating. Look for the Energy Guide label.
Where you place your dishwasher and clothes washer can also save you money. By keeping the (Insulated pipes, of course!) plumbing lines to the waer heater SHORT, you save temperature cooling. And consider designing your water heater close to both kitchen and bathrooms for greatest building and energy economy!
Designing your energy and water infrastructure for efficiency is step one in energy savings. Nothing can make up for large houses, long distance plumbing, or inefficient applieances. And you can end up paying many times the initial cost of the construction in your rising energy bills! Think ahead to save for years to come.

Sunshine is hot...water needs to be heated....whalah...combine them!
Solar Water Heating System
Solar water heating can use an Integrated Collector Storage system to preheat water. And solar water heaters are now eligible for some nice incentives in some states such as California.
Integrated Collection Storage systems (ICS) are best where there is no freeze danger.
You will get better performance from open look, active systems with a 40 square foot cllector and DC solar powered pump (for simple operation)
You can use a tankless gas backup for 77% efficiency.
What to watch for...beware of hot water recirculation systems without occupancy control. On demand systems can increase energy use by 3X. Ask your local utility company for their input on the best system configurations.

True smart water management technology is the most effective way to
achieve LEED certification (by USGBC) for outdoor water conservation.
Although a wide range of irrigation technologies are marketed as being smart, genuine smart water management systems are differentiated by:
According to WeatherTRAK, landscape irrigation systems based on this technology are 30 percent more efficient than traditional low-tech watering systems, speeding payback and eliminating infrastructure investments.
In California, AB 2717 and AB 1881 mandate that new construction include a weather based smart controller by 2012 and that cities/municipalities adopt smart irrigation by 2010. Other Southeastern states heavily impacted by recent droughts and water shortages are following California's legislative approach.
Although a wide range of irrigation technologies are marketed as being smart, genuine smart water management systems are differentiated by:
- No people involvement, because all irrigation activity is determined and executed by the system
- Low maintenance costs, unlike systems based on sensors and temperature gauges
- Ideal for both new construction and retrofitting, since they don't require the implantation of sensors, gauges or other in-ground equipment.
- Water savings for cost reduction
- Water savings for environmental impact
- Reduced risk by not damaging or creating slippery surfaces on hardscapes.
- Healthier landscape plants with scientifically scheduled watering to protect living assets

How Your House Works: A visual guide to understanding and maintaining your home, by Charlie Wing
Before my parents allowed me to drive, they suggested I learn how to change a tire and check the oil. And learn to read the dashboard widgets!
The same might apply to a house. The head(s) of every apartment and house might need to know the basics. How the plumbing can be shut off in case of a flooded room. How the thermostat works. How the bathroom stool works.
And in the throes of learning how to take care of these minor emergencies, it just might happen that you learn how to make minor repairs that will save you many "retail" level repair bills, and give you the satisfaction of truly being the king or queen of your domain.
This book is a good start in the right direction. It gives clear visual diagrams to help you see beyond the obvious skins of modern magic.
Dual flush toilets have become standards in Europe and other countries concerned about their water supply. Unfortunately, water conservation is undervalued in the US. But that is changing, especially where drought is forcing water outages and increasing rates. Gerber provides high efficiency toilets, sinks and certified water efficient solutions. Gerber offers vitreous china pedestal and drop-in lavatories designed to complement their toilets, bringing together classic looks and powerful technology. The advanced HP2 and XP3 high-performance flushing systems will virtually eliminate the aggravation and cost of warranty callbacks from second-class toilets that clog or require a “double flush.”
Abigail™ faucets, and Viper™ toilets with Gerber's HP2 flushing system, which delivers performance that’s more than double the industry standard! Gerber provides you with the style and quality you need to give homebuyers who are stepping up from their first home the sense that they’ve truly arrived.
Gerber offers water-saving, sensor-operated electronic faucets designed to prevent waste by automatically shutting off water flow. Deckmount choices include gooseneck or crescent spouts, as well as, models
equipped with an in-deck mixer, which permits user control of water temperature.
Ultra Flush® 1.1 gpf toilet models are available to deliver the ultimate in high-efficiency water conservation.
They can flush 1,000 grams of bulk waste while using 30% less water than standard 1.6 gpf toilets. In addition to Ultra Flush 1.1 gpf units, Ultra Dual- Flush™ models are also available, with a dual-action lever that permits 1.6 gpf or high-efficiency 1.1 gpf operation.
Ultra Dual-Flush™ provides professional performance while conserving natural resources. It flushes up to 1,250 grams of bulk waste per 1.6 gallon flush or 1,000 grams per 1.1 gallon flush. 1.1 gallon flush uses 30% les water over conventional 1.6 gallon toilets. The Pressure-Assist system uses pressure from the incoming supply line to foce 1.6 gallons of work out of 1.1 gallons of water. It installs like standard gravity toilest -- no special connections are required.
Gerber products are sold exclusively to the plumbing professional.
Gerber Plumbing Fixtures corporate offices are located in Woodridge, Illinois. Gerber has manufacturing facilities in Kokomo, IN, Laredo, TX, Montreal, Canada. Shenzhen, China and Weifang, China.

The old fashioned bathroom stool can use up to 3 gallons of water per flush. New toilets use considerably less and the new "dual flush toilet" lets you save the most. The flush button for "light flush" uses lss than a gallon of water, and the heavier flush (for solids) uses about 1.5 gallons. These amounts vary by product and by certification by trusted programs such as EPA's Watersense standard.
Designed in Australia, where water conservation is extremely important, the HET dual flush water-saving toilet uses, at most, 1.6 gallons per flush. “Dual flush” means that this toilet has two different types of flushing. One for liquids (or #1), which is only .8 gallon of water, and one for solids ( like #2, c’mon let’s be grownups about this!), which is only 1.6 gallons of water. At its biggest flush, this water still uses less than the standard new toilets, which use 1.8 gallons of water per flush. That’s up to 50-75% savings!
Remodeling doesn't always mean ripping out walls -- if you think green, you can rip out utility costs!
"Recycled water is a new
energy source," said Grant Davis, assistant general manager of the
Sonoma County Water Agency. "Water and wastewater that you'd normally
have to treat and dispose of will become the source for heating and
cooling."
They estimate savings of 90 percent on natural gas and about 50 percent on electricity for heating and cooling. The environmental benefits are hard to quantify - but the county is working on it. Under the wastewater recycling plan, 55- to 60-degree water would be pumped from the treatment plant to the business park through underground pipes into a pump inside each building. Once in the pump, a refrigeration device transfers heat to or from the wastewater. A compressor converts that heat energy into warm or cold air that can be pushed through about 3 million square feet of office space at the business park, replacing the traditional heating and air conditioning systems.
In this "open" system, the water could also be used to irrigate landscaping, or, with a secondary set of pipes, flush toilets. Otherwise, the chilly or hot water - between about 40 degrees and 150 degrees - would pass through underground pipes to two adjacent reservoirs.
The wastewater recovery system could work particularly well for small or midsize cities or suburbs where the energy needed to pump water to low-slung buildings is much less than for skyscrapers.
Why?
"We all know California will have severe droughts in the next 20 to 40 years and that will affect water supply," said Gary Geernaert, director of the Institute of Geophysics and Planetary Physics at Los Alamos National Lab. "This will help us make educated guesses about what the pressures will be on the public and private infrastructure and help build that into the design."
The project has gained steam in the past few months as Pacific Gas and Electric Co. and some of the biggest names in the wine business have signed on; in March, county supervisors approved $1 million for a feasibility study. The flurry of interest comes as more cities and businesses take a hard look at their contributions to greenhouse gas emissions and climate change, and national labs expand their research to include not just military security, but water, energy and economic security.
Sonoma officials will meet with lawmakers in Washington about allocating money for this project and establishing a fund, similar to the Community Development Block Grant Program, to pay for similar projects all over the United States. In addition to federal money, Sonoma is considering revenue bonds and creating a special assessment district.They estimate savings of 90 percent on natural gas and about 50 percent on electricity for heating and cooling.
