Build It Green 20/20 Presentation

"Pecha Kucha" is a presentation style that was born in 2003 in Japan by design students looking to share their work in a new and fun way. Each presentation consists of 20 slides that are each explained for 20 seconds. The presenter therefore has 6 minutes and 40 seconds to talk about their subject. Strict adherence to the rules makes the presentations challenging and condenses the subject to its essence.

Build It Green, a non-profit based in Berkeley that promotes green building and education, thought this presentation style (renamed "20/20") would be a fun way to share information between members. Build It Green sponsors "guilds" of building industry professionals in each major area of the bay, hosting monthly discussions regarding green building related topics. Chris Donatelli values his membership to Build It Green and has enjoyed attending the South Bay guild. On Tuesday May 3rd, Chris took the opportunity to do his own 20/20 slideshow. He focused on a specific project that our company completed in the Spring of 2009.

The all new home featured a structure made of SIPs (structural insulated panels). These consist of 2 sheets of plywood with 5 inches of foam btween. This creates a very strong and efficient home. The heat is provided by radiant floor heating and a super efficient water heater with solar input. Interior finishes that are low VOC (volatile organic compounds like formaldehyde) and heat recovering fans that exchange interior air with fresh outside air. These are just a few of the features that helped us achieve a Green Rated score of 140. All in all it is a very comfortable and efficient home that the owners are very proud of and happy with.

Chris was glad to share what he learned in the process of building this home and what it was like to have clients that were so excited about green building and driven to make a very green home a reality.

"One Job for America"

Chris Donatelli Builders participated in a national project that was started right here in the bay area. Carla Emil, a advertising executive working with art and education related non-profits, came up with an idea meant to inspire growth and hope for our slumping economy. One Job for America asks companies across America, regardless of size, to pledge that they will add one person to their ranks. One new hire in a company (especially a larger one) may not seem like much, but by multiplying this around the country the plan is to create a significant impact to the economy. Ms. Emil does not claim to be an economist, a politician or a academic. The inspiration was to use a "grassroots" campaign to succeed where big government and various advisers had failed.

Chris Donatelli was interested in this approach and hopeful in signs that the residential building industry in the bay area was starting to pick up again. He decided to pledge one job and take part in support for this idea. Shortly thereafter, a sales/estimating associate was added to the office staff of Chris Donatelli Builders. Chris' participation, along with a other local companies, was picked up on by a writer for the San Francisco Chronicle in the article One Job for America: 1 Marinite's Idea for the Economy

Showerheads and Faucets Go with the Flow

Showers and faucets combined, use about 1/3 of household water. A large portion of this is heated using either electricity of gas. Therefore, new technologies are not only saving you water, but are also helping out with the rest of the utility bill.

Federal Standard for a showerhead flow is set at 2.5 gallons per minute (GPM). The WaterSense program goes better with a 2.o GPM requirement, while also requiring testing protocols for reliable pressure and even spray. In order to keep good spray pattern and coverage, manufacturers are using new technology to provide the same shower experience.

Showerheads come in two types: aerating and non-aerating. Aerated means that air is injected into the water as it goes through the showerhead. This creates larger drops, but can cause water to cool faster (since air cools more quickly than water). Your lower legs and feet might notice the difference. Non-aerated showerheads use a pressure-balancing flow restrictor. The shower can be stronger, but the force of the water may be too sharp. It basically comes down to personal preference.

Federal Standards for faucet flow is 2.2 GPM, while WaterSense is at 1.5 GPM. New low-flow faucets are seen as more a part of a remodel, rather than a stand alone upgrade. They can help qualify for points when appealing for green building certification as well. Flow can be easily adjusted during use on any faucet. Low-flow aerators are an easy modification if you want to keep your existing fixture. "On-demand" controls can help to save water and energy by making it easier to turn the water on and off. Electronic faucets use infrared beams, foot controls can operate while you hands are full and simple aerator bars put control right where the water is.

Water fixture technology now provides performance with efficiency. Styles and finish choices are numerous and options for control layout are available. Click here to search for products with the WaterSense label. Your design requirements and water needs can be met in a variety of efficient ways!

Water-Saving Toilets & Washers

Staying on the subject of water use, I want to now draw attention to the two highest water consuming fixtures in the home. Toilets and washers account for almost HALF of water use in a residential home. By focusing on new rating systems and available technology, we can drastically reduce water consumption. As I stated before, California is very drought prone and has the unfortunate condition where peak consumption occurs at odds to peak rainfall. The state also has a projected populaton of 60 million people by 2050! Making water-saving fixtures standard in homes can have a huge impact, now and in the future.

Toilets are a feature in the home that is definitely taken for granted. If it is not working, it can be a real problem. Conversely, we use the toilet multiple times per day, maybe not realizing how much water use it is creating. Older model toilets can use as much as 3 gallons or more, each time it is flushed. Have a larger family? If a family of four each use the toilet 3-4 times a day, that can add up to 330 gallons PER WEEK! A federal mandate established in 1992 now states that new toilets can only use 1.6 gallons per flush (GPF). The EPA WaterSense programs goes further with a 1.28 GPF requirement. Also under the 1.28 GPF program can be a "dual-flush" toilet, which can offer 1.6 GPF for solids and 1.1 GPF for liquids.

Traditional "gravity" flush toilets can work fine using 1.28 GPF. "Pressure-assist" toilets use air and water from a pressurized tank within the porcelain tank of the toilet. Clogging is not often an issue. These are popular for commercial applications, yet do cause a lot of noise for a residential home. One of the newest products is a "vacuum-assist" toilet. This type uses a special tube that diverts air from the filling tank to the actual trap of the toilet. This air pocket will create less water to fill the bowl, while also creating a gap in the line. This pocket will then cause a vacuum when flushed, drawing waste down the line with operation similar to traditional "gravity" units. All these types can be found in models that price for around $300.

If you don't want an entire new toilet, retrofit kits are also available. These will replace your existing flushing mechanisms with a dual-flush operation. These kits will usually run at about $30. Look for the GPF ratings so that you can be sure to meet WaterSense requirements.

Clothes washers are a bit more tricky to quantify water use. Since washers can come in different sizes and have different cycles, a standard rating had to be created. The Energy Star program therefore created the "water factor" (or WF) rating. This calculated the numbers of gallons used per cycle PER cubic foot of washer capacity. The lower the number, the more efficient the washer is. The federal standard WF is 9.5, while the WaterSense requirement is a WF of 6. Technology can help to play a role here, with specific cycle options and "load sensing" (much like a dishwasher) that can determine how dirty clothes are and how much water is needed to clean them. Highly efficient units from Frigidaire, Samsung and LG all have a WF of around 3!

As you can see, the products you need to use less water in your home ARE available. The good news is that they are also affordable, becoming a new standard as we move towards greater efficiency and performance for your home.

Water Efficiency Standards & Practices

Water usage is becoming more of a concern for developed areas. Populations are steadily increasing while water resources are staying the same (or in shortage depending on the weather of any given year).

Water efficiency can have some small paybacks in utility bills, but there is more of a "big picture" perspective to take. The distribution, purification and heating of water uses large amounts of energy. Also, the more water we use, the more our waste systems are stressed. By cutting water shortage on a large scale, the payoff will come in the form of fewer water shortage periods, higher energy availability, less pollution and more efficient waste processing.

Federal mandates for water efficiency have been established by the department of energy. These are seen as the most basic level of water consumption for fixtures such as toilets, showers, faucets, dishwashers and clothes washers. The Environmental Protection Agency (EPA) has also established the Water Sense program, which takes efficiency even further and undercuts federal standards significantly. However, the technology available in modern fixtures and appliances can still achieve these numbers and are price competitive. Look for the official "water sense" label:

or search for approved products here.

The bonus when shopping for water efficient appliances, such as clothes laundry and dishwashers, is that they are often EnergyStar rated as well!

When examining your home for water efficiency, even before you switch out appliances and fixtures, you may want to start with looking for LEAKS.

Studies show that leaks account for about 14% of indoor water use. That is almost as much water as either bathroom faucets or showers! It can be amazing what a few drips can add up to over time! Not only is the water wasted, but it can be causing damage to the home. Look for dripping faucets or toilets that keep running. Check out the connections under your sinks. Look for water stains at the bottom of walls or on a ceiling. Many homes in the Bay Area are older and may contain water piping that can now be corroded and weak, with leaks at joints and fixtures.

Whatever the size of your home and family, using water efficient products and practices can create significant savings of this precious and irreplaceable resource. Additionally, if communities, cities and regions can band together to commit to water efficiency, the results will be of a larger scale and the rewards may span into generations to come.

Trade Contractor Interview: Dallas Carlock of Carlock Plumbing

We sat down with Dallas Carlock to talk plumbing. He has been a trade contractor for Chris Donatelli Builders and has owned and operated his own plumbing company since 1980. We wanted to tap into his experience and perspective in regards to how plumbing affects a job and what homeowners can look out for.




What is the story with tankless water heaters?

• They only fire-up when hot water is needed, saving energy over the long term.
• A large family with continuous use will create HIGHER energy bill (due to larger burner in the tankless unit)
• New technologies in TANK water heaters and boilers are now more efficient, giving a family a choice to use what fits their lifestyle.
• Proper installation, such as gas line size, is essential.

What is a hot water circulation system?

• "Circ pumps" are installed on a hot water line that does a loop through the home.
• When hot water is needed at a fixture, the homeowner presses a button to activate pump.
• The pipe will circulate the water through the lines while it is heating up, saving water from going down the drain.
• A point of use pump can also be installed, bypassing the creation of a loop in the plumbing.
• These systems can be used with a tank OR tankless water heater.
• Again, proper installation is key. If not done properly, the system can corrode pipes, wear out equipment and cause energy loss.
  

How is water efficiency is increasing?

• Toilets have new designs to flush better using less water.
• Shower heads have new water saving designs that still provide comfortable experience.
• Filltration units now waste less water and provide better taste.
• Essential minerals are no longer wasted and salt is not introduced into sewer system.
  

H0w does fixture choice influence a project?

• Best to make decisions as early as possible.
• Changing a fixture in the midst of the project can lead to re-working waste or water lines, leading to more labor charges to the client.
• Having specifications on fixtures will aid in communication between client and contractors

What is going on with solar thermal systems?

• They combine solar input to water heating systems and lead to less utility usage.
• Work along with water heater and even space heating.
• Proper design and equipment choice is key due to complexity of systems.
• Tax refunds are available to homeowners.
• Solar thermal systems can be MUCH more affordable than solar power systems.

Lead Safe Work Practices Now Required

As of April 22nd, all contractors involved in remodeling work of pre-1978 residential homes or child-occupied facilities must be certified by the EPA for using "best practices" in reference to lead paint.

Lead was added to paint in the first half of the 20th century as an agent for durability. Lead helped to protect the paint from weathering and mold/ mildew. Unfortunately, it has been found that lead can have adverse affects on the human body. Lead can affect the circulatory system, the kidneys, the gastrointestinal system and most notably the nervous system. Children and pregnant women are much more at risk, due to the state that their bodies are in. Children exposed to lead can have developmental and behavioral problems, lowering IQ or even leading to personality issues or aggression. Any neurologic damage that takes place is permanent. Children and pregnant women have been shown to absorb up to 50% of lead that they are exposed to, compared to 10-15% for an average adult!

The main avenue of transmission is by breathing in dust that contains lead particles. Peeling paint provides chips that are then worn down to dust. Lead can also be ingested directly as paint chips or from hands covered by lead dust.

New gudelines from the EPA require contractors to be certified in "safe practices" for lead paint. This translates to providing proper information to clients (in the form of a EPA pamphlet) , sealing off work area from rest of home and cleaning job properly with dust containment as the prime focus.

Chris Donatelli Builders now has staff with this EPA certification. We are ready to assist you with any remodeling work no matter what the age of your home!
