Sustainable Building Visit: Marketable 2000 Sq. Ft. Tucson Home is “Super Energy Efficient”

Last week, I had the pleasure of visiting with Tucson builder Michael Ginsburg (pictured below) of La Mirada Homes at his new Super Energy Efficient Design (S.E.E.D.), ENERGY STAR rated home (pictured below) in Tucson, complete with radiant heating AND cooling in the concrete floor slab and 3.4-kW of solar photovoltaics on the roof. Michael’s sustainable building design shows a HERS (Home Energy Rating System) of 20, meaning it uses 80% less energy than a conventional home.

A beautiful, 4 BR, 2 BA ranch style home that fits in perfectly with its central Tucson desert environment. Another plus, no internal load-bearing walls, so you can configure your own version anyway you want it. This sustainable green building is super-insulated, so it’s incredibly comfortable, even on the 103F, high-humidity (monsoon season) day that I visited. All the good green features: solar water heating, rainwater harvesting and a whole-house fan for fresh air ventilation, overhead fans and NO NEED for forced-air A/C (but it’s there if you really need it). Certified ongoing by Davis Energy Group, one of the nation’s oldest and best energy consultancies.

Pyramid of New Water Sources

A conceptual breakthrough for thinking about how to meet our future water needs. Check out the Pyramid of New Water Sources, Jerry Yudelson’s new tool to show future water supply sources, a pyramid with ten steps of increasing cost and complexity.

Download the Pyramid of New Water Sources
(PDF 175KB)

The Pyramid of New Water Sources ranks the following measures:

Changing behavior, with better information and codes
Low-cost/no-cost measures, such as fixing leaks and lower water-using fixtures
Irrigation measures, including native plantings and drip irrigation
Hygiene, such as water-free urinals and low-flush toilets
Appliances, such as water-conserving dishwashers and clothes washers
“Extreme Makeovers” that include composting (no water) toilets, hardscape landscaping and onsite blackwater treatment and reuse.
Water heating, one of the biggest energy users in the water cycle, including hot water recirculation loops and solar water heaters
Onsite reuse, including rainwater collection and graywater for irrigation
Offsite reuse, using reclaimed water from “purple pipe” systems and even “sewer mining”
Desalination and new water sources, such as creating potable water with reverse osmosis treatment of reclaimed sewage

I think this is a great new conceptual tool. I’d like your thoughts.

My Top Ten Green Building Trends for 2011

I say that the green building industry will rebound strongly in 2011 in spite of the continuing economic difficulties in most developed countries, and I think 10 major trends support this prediction.

What we’re seeing is that more people are going green each year, and there is nothing on the horizon that will stop this trend. However, in 2010, the slowdown in commercial real estate construction in many countries put a crimp in the start-up rate for new green building projects. In putting together my Top Ten trends for 2011, I’m taking advantage of conversations I’ve had with green building industry leaders in the U.S., Canada, Europe, Asia, the Middle East and Australia as I’ve given green building keynotes and presentations all over the world during the past year.

Jerry Yudelson’s Top Ten Green Building Trends for 2011 include:
1. The worldwide green building movement will continue to accelerate, as more countries begin to create their own green building incentives and developing their own Green Building Councils. More than 70 countries, on all continents, will show considerable green building growth in 2011.
2. Green building will rebound in 2011, as measured by the new LEED project registrations as a proxy for this growth. The dramatic slowdown in commercial real estate construction in many countries was not offset by other sectors such as government, and so the growth rate of new green building projects fell dramatically in 2010.
3. Green building in the U.S. will continue to benefit from the Obama presidency with a continued focus on greening the executive branch. New announcements of a commitment to a minimum of LEED Gold for all new federal projects and major renovations confirm and highlight this macro-trend.
4. The focus of the green building industry will continue to switch from new buildings to greening existing buildings. The fastest growing LEED rating system in 2010 was the LEED for Existing Buildings program, and I expect this trend to continue in 2011. “My 2009 book, Greening Existing Buildings, documents the strategic components of this trend.”
5. Blue will become the New Green. Awareness of the coming global crisis in fresh water supply will continue to grow, leading building designers and managers to take further steps to reduce water consumption to increase sustainability. This will be done in buildings through the use of more conservation-oriented fixtures, rainwater recovery systems and innovative new water technologies. My latest book, Dry Run: Preventing the Next Urban Water Crisis, shows how to do this in green buildings all over the world.
6. Zero-net-energy designs for new buildings become increasingly commonplace, in both residential and commercial sectors, as LEED and ENERGY STAR ratings become too common to confer competitive advantage.
7. Performance Disclosure will be the fastest emerging trend, highlighted by new requirements in California and other states. Commercial building owners will have to disclose actual building performance to all new tenants and buyers.
8. Certified Green Schools will grow rapidly as part the LEED System. This trend will accelerate as understanding of the health and educational benefits of green schools grows. Already by mid-year 2010, green schools represented nearly 40% of all new LEED projects in the U.S.
9. Local and state governments will step up their mandates for green buildings for both themselves and the private sector. We’ll see at least 20 major new cities with commercial sector green building mandates. The desire to reduce carbon emissions by going green will lead more government agencies to require green buildings.
10. Solar power use in buildings will continue to grow. This trend will be enhanced by the increasing focus of municipal utilities as they need to comply with state-level renewable power standards (RPS) for 2015 and 2020. As before, third-party financing partnerships will continue to grow and provide capital for large rooftop systems such as on warehouses. However, we may very well see a slowing of large solar and wind systems, as federal grant support, in lieu of tax credits, is phased out.

I’ve added two “bonus picks,” strongly emerging trends, to this list: First, there will be a continually growing use of software and the Internet “cloud” in green building design, construction and operations; Second, the revolution in sustainable building materials is gaining momentum each year, one that gives higher performance at ever lower costs.

Let me hear from you. What are your picks for the Top Green Building Trends of 2011?
