This new remodel project in Berkeley is underway. They are doing a full house remodel and are smart to make sure that the exterior envelope is in good shape. In our climate these zero overhang stucco houses with old fashioned stucco details (stucco all the way to dirt and no weep screed) often have a lot of rot hidden behind the stucco. You can see some of it in the photos below. The next step will be to remove all the old sheathing and check the studs for rot. After repairing any rotten framing, the contractor will add new plywood sheathing and replace all the windows with modern double glazed models.

My friend Carl Milsum just installed this simple and sturdy new aluminum entry roof to protect visitors at his front door.  It might look better without the diamond plate, but I think he got a special deal on this material.

On Tuesday I visited the Water Conservation Showcase at the Pacific Energy Center.   Water-saving products large and small were exhibited.  There were many irrigation products including ET Water’s Quickdraw timers controlled from your cell phone and time release water capsules from Driwater. Niagra Conservation gave away a Stealth Toilet that uses .8 gallons per flush as a door prize. Unfortunately they did not have a demonstration toilet on display.  D’mand Systems was there with their latest models of pumps to recirculate the lukewarm water back to the heater and not down the drain.  CUDO water storage system showed off their stackable cubes for water storage.

Pacific Interlock demonstrated their porous paving stones. It was enlightening to watch them pour a glass of water directly on top of the paver and it soaked right through. I had been under the assumption that porous pavers meant pavers with holes for water to drain and plants to grow through. These look like conventional bricks, just have tiny pores to drain the water.

There were also many representatives of grey water and black water treatment systems.  I think you get pay back pretty quickly on a large building or development if you can recycle some of your water. These systems are still too expensive for the average single family home owner.

In a place like the bay area, where rainfall is concentrated seasonally, storage often does not make sense.  It is more practical to use rain water in wintertime for wash or toilets, and to reuse shower and sink water for toilets and irrigation during summer. Expensive filtration is required by code for any reuse of rainwater or grey water for plumbing purposes. It is now permitted in many jurisdictions to use grey water (only from laundry and bathroom sinks and showers,) for irrigation without filtration.

Dual flush toilets are another great way to conserve water!
