Water remains my favorite and most important issue when addressing green building
concerns. It is certainly not the most important topic when looking at the
various certification checklists, like the USGBC LEED rating system. It finally
received a prerequisite in the last update, but is dwarfed in the overall point
scale by considerations for energy and materials.
Energy indeed has gotten a lot of attention in the last few months, especially the
concept of net-zero energy. The net zero concept is very appealing by taking
advantage of the existing infrastructure rather than having to create a full
independent power storage unit. Typically the consumption averages out to zero
over the term of a 12 month period.
The same concept can be used for the consumption of water; essentially creating an onsite
water filter systems. Water will not be able to quite be net zero, due to
evaporation and other environmental factors that are undoubtedly part of the
cleaning process. But a recycled water loop will probably be about 95%
effective. The remaining 5% can easily be made up by rain water or a well,
depending on the geographic location of the project.
The interesting part to me is the energy that is required to move and clean water.
By bringing this aspect of water use directly to the project, much energy can
be saved on the moving of water to and from the project and the reality of net
zero energy and water is much more realistic to attain.
Considering now, that in California for example about one third of the state’s energy is
used to clean and transport water, it does seem a little like putting the stick
before the carrot…
I am grateful to be part of a cutting research project at the University of Miami
that is addressing this very topic: The net zero water dorm. This project will
have move students into a retrofitted hall to be the live users of on-site
cleaned water – all water, from sinks, showers and toilets.
What can you do for your own project? Continue to focus on water reduction in daily
use and install conservation features in your renovation and new construction.
Dual flush toilets or even composting toilets are readily available. Low flow
shower heads and faucets are standard for all manufacturers and a rain
collection system such as simple rain barrel can be installed in any project.
Use the best suited system for water heating, be it on demand, solar or
conventional tank with a PV panel to power it. By using water intelligently,
the use of energy can also be reduced. Why not be the first house to clean your
own water?

It is with great pleasure that I continue to lecture on how to green your home and business, provide workshops on green building certification and continue teaching about contemporary sustainable design at the University of Miami.
Still, I frequently get the same question when noting that my architectural business focuses on sustainable design: What is that… and what does it mean?
We read about greening this and saving the planet in that way, how to recycle your plastic bottle, use your own bags for groceries and change a light bulb to save energy. The publications and articles about “green” are plenty and stretch across a wide variety of sectors; real estate, fashion, construction, food & wine and many more. Still there remain many people out there, that are not sure what this trend all means and why and how it affects them.
Well, it is not a trend and it will most certainly affect you and your children. The words may be trendy and will likely change over
time, but the meaning remains valid. So here I offer a basic introduction to the topic from my perspective.
What is green design and sustainable building? …do I paint my house green to be a green building? …is it all about energy savings? …does it have to be certified?
Sustainability is the basis of green or better sustainable design and construction. Sustainability being defined as “meets the resource needs of current generations, without compromising those of future generations.” It depends on where you look, that might be one or seven generations, but the principal remains the same. The construction industry, when considering material harvesting and manufacturing through design and construction to operations and maintenance is probably the largest consumer of resources; including water, energy, natural resources and generation of waste. In order to be sustainable, the industry must
change to incorporate better practices that are less harmful to the environment and reduce the need of resources. This is the foundation of sustainable design and construction.
To make this work however, something else must be considered. A multitude of factors must be in balance for these changes to be
effective and permanent. In the industry we call this the “Triple Bottom Line”.
Think of it as a three legged stool. All three legs must be stable, in order for someone to sit on it… same with the following principals:
Environmental considerations: Doing the right thing for the environment; creating healthier environments to live and work, reduce the strain on natural areas and resources.
Economical considerations: We have to make a living, so there needs to be a reasonable profit involved under the current market economy that we live in.
Social considerations: The people at large must be able to use it and be comfortable using it. It must serve the welfare of the general public and it must be accepted culturally.
Take energy for example, specifically Photovoltaic’s. The idea is not new. But when first created and installed, the inventors created odd looking structures that were not socially accepted: they had the right idea to save money on energy and reduce their environmental impact; but the social factor prevented them from becoming main stream and make a lasting impact…
Now think that you can do business and make a profit by doing the right thing and create something beautiful and lasting… that is what sustainable designers strive to do!

Recently I was asked a simple question, at least a simple question for a practicing architect and designer: What is your favorite building in Miami?
Immediately a number of structures came to mind, none of which I actually really liked. Worse, I could not think of a single building that either embodies something spectacular from a design perspective or truly outstanding from its integration into use and site. How would I choose the one building that I would be proud to put my seal of approval on?
Next, I thought about a possible witty or funny response, but most of the structures that I have been involved with as principal of Sebastian Eilert Architecture were custom-made or purpose-driven and thus really must be considered very subjectively and would likely fail as Miami’s best building in any other persons view.
Now there are many examples of recent buildings, as well as a pool of historic structures, that have many features that are appropriate for our climate, passed the test of time and embody a spirit of good design. So was I to focus on choice of materials such as residual Dade County Pine, Coral Rock features and other environmentally preferred materials? What about good site placement and integration into the city’s fabric? After all, no building alone should overpower its content and neighboring environment. Or should I look into the historic integration of solar technologies, natural ventilation and landscaping choices for water savings? Then there is the workmanship of the contractor. After all, we architects are generally noted for “only” imagining things, when it is the contractor that will bring our ideas to life…a good contractor equals a good project.
Regardless, there are too many variables at play to truly make a singular statement and case for Miami’s best building and my list of good examples slowly grew. Still, the other side of the ledger far outweighs the good buildings, but there are numerous to be had.
I also recalled that I was part of the AIA Miami’s effort to compose a book of Miami’s architecture and remembered that the list composed and typology was indeed vast. There are so many great examples ranging from residences, to city halls (Hialeah, for example) to airport hangers. Renowned architects from Alfred Browning Parker to Hilario Candela have contributed high quality design for decades and a number of younger spirited individuals are making their mark today, such as Chad Oppenheim, Maricarmen Martinez of Upstairs Studio, Max Strang and, yours truly, Sebastian Eilert of Sebastian Eilert Architecture.
In the end I try to minimize my design perspective and focus on sustainable issues, and like to offer the following list, in no particular order or any claim for it to be complete:
- Village of Pinecrest, Pinecrest Garden Lower bathroom: Yes, one of my buildings, but noted here because I have had numerous positive feedback about how the new structure blends into the site and appears to have been there from the start of the park. Integration into the environment at its best. Thank you!
- Marine Stadium: This iconic Miami structure is currently fighting to be preserved and keep its place as part of Miami’s history as well as earn a future spot! Join www.MarineStadium.org to help ensure its survival.
- Old Miami High: Miami’s first high school now preserved for many generations to enjoy.
- M+M Residence: the home of Maricarmen Martinez, owner of Upstairs Studio is a fantastic example of contemporary residential design based in mid century principals and incorporating many sustainable features, materials and systems, such as PV to offset 60%+ of the FPL bill. It was a pleasure to assist in obtaining the well deserved LEED certification.
- The Biltmore Hotel: This wonderful Coral Gables icon is a simple masterpiece of its time and anyone who has stayed, dined or simply visited knows why…
- Coral Gables City Hall: Understanding the original designed master plan of downtown Coral Gables, provides an alternative perspective on its orientation and part of the grid that has been lost in recent development. Regardless, the building maintains its charm and importance for the City Beautiful.
- The Bacardi Building: Love the stairs!, and who can pass by the elevation without noting and appreciating the deep blue mural.
- Vizcaya: The original party house by the bay. Waterfront, pristine and well maintained garden and still in use today. I strongly recommend to attend one of their signature events (4th of July, Halloween and New Years Eve): there is no other party in Miami that can evoke the original spirit of its early residents.

SEA is proud to have completed another great kitchen upgrade. The home of Mr. Bill Murphy along historic South Miami avenue built in the 1950’s was the target and provided the grounds for the latest completion.
View of kitchen - before
The original kitchen was nestled in the front of the house separated by a saloon style door. Adjacent to the kitchen was a partial laundry and storage area that also held the water heater and lead out to the utility patio and daytime home for Mr. Murphy’s pups!
Murphy living/dining room - before
The home features an amazing showcase of solid wood products that have been partially installed with the original design of the house and were also added on by previous owners. The amazing warmth of this material were the inspiration for the renovation and color scheme for the renovation.
The design included the removal of the common wall between the kitchen and living room to open up the feel of the compact home. Extending the counter to double serve as a breakfast area, and replace a small cramped table inside the kitchen, as well as to tie the kitchen into the open space for entertaining also brings natural light to the rest of the living dining area. The project also removed a large A/C duct chase that then exposed the amazing clerestory windows and further illuminates the room naturally.
Murphy kitchen - after
The new kitchen pushed out the laundry across the utility courtyard and replaced the clunky water heater with a on demand heater, perfect for the use of the household.
The kitchen then received a new terrazzo floor to keep it easy to clean. Colors form the existing wood and new cabinets were used in the terrazzo.
The new cabinets by Armando Garcia Custom Cabinets Inc. are a delight and have been installed to the highest satisfaction of Mr. Murphy. Appliances are Thermador and Bosch and the counter is Ceasarstone with a glass tile backsplash. Of course non VOC paints and sealants have been used in the project throughout.

Annotations on 7 Xeriscaping Principles for South Florida
(created by Ronald E. Mossman, Ph.D., edited and revised by Sebastian Eilert, AIA)
- DESIGN: Select low maintenance plants. Use few flower beds and only near entrances – not a ring of flowering plants around each tree. Evaluate the site for daily and seasonal wind and sun exposure. Buffer NW winter winds and lightly shade SE areas. Shade the AC compressor and west-facing wall. Determine major Residential uses: public, private, service and shade accordingly.
- PLANT SELECTION: Group plants by water needs. Native and regionally appropriate plant community and other plants with specific water tolerances (water, soil, light, salt and wind). Plan for different species to be in bloom each season. Select for wildlife food sources as well as human food sources. Select plants for their mature size, avoid instant landscape. Give the plants room to grow properly.
- IMPROVE SOIL: Compost flower beds, vegetable gardens and trimmings. Mulching gradually adds nutrients from decayed organic matter already in your environment.
- USE TURF WISELY: Xeriscaping principles suggest that 10% or less of the property should be lawn. Turf uses 50-60% of residential landscape water. Irrigate in the early morning. Water is only needed when a footprint can be seen in the lawn after you walk across. Cut at the highest mover setting and use a mulching mower. Use St. Augustine “Floratam” sod
- IRRIGATE EFFICIENTLY: Limit irrigation to first year after planting for non-turf areas such as bedding and patios. Use drip or micro irrigation systems and include recycled water from the roof and redirected water from paved areas.
- MULCH: Mulch assists in holding water in the soil by restricting evaporation. Mulch reduces soil temperature by up to 10 degrees compared to bare soil. 18% of all US waste is yard waste! Get mulch from local sources and keep timings from your own yard.
- MAINTANCE: do not rake and collect grass trimmings. Spread grass trimmings that are left to rot return nutrients to your lawn. It has been shown that 40% more nitrogen fertilizer must be added to return what has been lost in removal – a waste of money and energy. Keep fertilizers and pesticides to a minimum and use integrated pest management (IPM). Allow natural predators such as lizards, snakes, ladybugs and use clandosan. Read fertilizer labels and use appropriate fertilizer for correct plants. Practice selective pruning and raise canopy to channel wind from the Southeast to reduce temperature around your house and yard. Regularly check your irrigation system for leaks and damage as well as proper coverage.

After going over so many possible options to improve the energy efficiency for your home I find it time to put together an official weatherization package.
There are plenty of rebates currently available and even more are coming in the next few weeks and months. This is indeed a great time to look at energy improvements for your home and small business. Not just will you be able to significantly improve your operating cost, but the Government will help you pay for it. The upcoming incentives are certainly a positive aspect of the recovery act that has found its way to the end consumer.
In other posts we already looked at LED’s, appliances and general saving, specifically relating to South Florida. Please look at the “Greening your South Florida Home, Part I, Part II and Part III.
A concise Weatherization package should include at a minimum the analysis of the windows and doors, insulating in the walls and especially in the roof and attic. These simple primary starting points can lead to substantial savings in a very short time by controlling your building envelope. Energy savings do not end with the way you use your shell; it is only the beginning.
Consider additional energy and water savings with other improvements such as HVAC update and roof replacement. There are also rebates to update your water heater, dishwasher and refrigerator.
The homestar retrofit rebate package is the governments’ incentive under the Recovery act to provide partial funding for improvements for homeowner for reducing their energy bills. Regardless of this package, there are many sensible options to improve the use of energy in your home.
More information about the Homestar pacakage can also be found here.

Here is the next installment in the “quick and dirty” rundown of simple quick tips to improve your home and make it a more green building; for your health, for your wallet and for your overall well being…
Part I will focus on small to no budget items (please see previous post of Part I)
Part II will look at medium expenses or items to look at if they break and need (NEED!) replacement
Part III will look at the big changes that will have a lasting impact on your life 9from a green building perspective, but who knows, maybe more…)
Part II. What really works:
Lighting. If you started with the light bulbs but want to do more or have limited opportunity for changing light bulbs, evaluate your entire lighting system. Install dimmers, replace old fixtures, preferable with LED’s. This is particularly effective for recessed lighting fixtures (such as the ones replaced in the Alcaraz-Arango kitchen). A pleasant side effect is that the heat effect from the lights will also be reduced, thus reducing the need to cool down the house/space i.e., use less Air Conditioning.
Air Conditioning. The general rule is to look at a unit when it is 10 years or older. Typically systems have advanced in efficiency and the payback to upgrade can be realized in 4-6 years. Look for the SEER value. This is the indicator of how efficient the unit is. Current code required a 13 SEER unit; a 16 or 17 SEER unit is considered high efficiency and 18+ SEER is very high efficiency. The later are a choice investment and should be evaluated for Life Cycle Cost and Return of Investment. (THIS OPTION WILL REQUIRE A PERMIT)
Remember to upkeep the correct filters and also clean the ducts, if you do not replace them.
Windows and Doors. After you have gone through your home and weatherized (sealed) the doors and windows they might still be too old and too leaky to properly seal the house. At this time consider upgrading your windows. Start with the single awning type glass windows and old school sliding doors. Also consider upgrading to impact glass and earn a possible deductible on your insurance policy. To go for top shelf, include low-E glazing and make your windows energy start type. The consumer label will lead you to the most energy efficient windows and doors and will maximize your bottom line savings.
Make sure you work with the right professionals and get quality installation to ensure excellent weatherization on your brand new items. (THIS OPTION WILL REQUIRE A PERMIT)
Landscaping and Irrigation. Look for some of the other posts for this topic. Under the mid level renovation, consider spending some money on a rain water collection system: Gutters and rain barrels. This will also help with erosion control around the edge of your roof line.
