In a typical home, 43% of the utility bill goes toward heating and cooling. 


Homeowners  want ready access to a variety of building methods that can make their homes more weather resistant and energy efficient.

Energy, Weatherization and Technology can incorporate energy efficiency into rebuilding technology options by educating contractors and homeowners on how best to repair or rebuild damaged homes in a more flood and wind-resistant manner.

These aren't usually cosmetic solutions.

The U.S. Department of Energy's Technical Assistance Project includes information and technical specifications that include renewable and energy-efficient technology suggestions for reconstruction.

The Oak Ridge National Laboratory has tested many high-performance building materials and provides municipalities and states with training materials and information on incorporating energy efficiency and renewable energy technologies into the rebuilding or repairing of flood- and wind-damaged homes.

Many local governments incorporates the energy efficiency and renewable energy technology materials into workshops and training materials for contractors and homeowners.

Some of the high performance technologies that are being tested and developed are found on the Department of Energy's division websites such as:


ORNL - Oak Ridge National Laboratory

DOE EERE  Energy Efficiency & Renewable Energy

Seasonal Energy Savings for Consumers  

Lawrence Livermore National Laboratory

Much of Livermore's research is at the molecular level and reaches into the depths of space, but some research is also directed to the natural spaces around us.  For instance,


Through research funded by the California Energy Commission, scientists from the Laboratory, the University of California at Merced, and the National Center for Atmospheric Research found that temperatures in California from 1915 to 2000 have increased by 1.16°C (2.1°F) statewide.

The research, which appeared in the March 2008, Supplement 1 edition of Climatic Change--dedicated to California's climate--also suggests that the warming may be related to human activities.

The team used data from nine sets of observational records and from a suite of climate model simulations of natural internal climate variability to analyze trends in California-average temperatures during the periods 1950-1999 and 1915-2000.

The researchers found large increases in mean and maximum daily temperatures in late winter and early spring, as well as increases in minimum daily temperatures from January to September. These trends are inconsistent with model-based estimates of natural internal climate variability, and thus require one or more external forcing agents to be explained. The researchers suggest that the warming of Californian winters over the twentieth century is associated with human-induced changes in large-scale atmospheric circulation.

Recent climate models have not been effective in explaining California's summertime trend, where warming mainly occurs at night.

Based on their previous research, the team suggests that lack of a detectable increase in summertime maximum temperature arises from a cooling associated with large-scale irrigation, which may have counteracted warming from mounting greenhouse gases and urbanization.

If this hypothesis is verified, the acceleration of carbon dioxide emissions combined with a leveling of irrigation may result in a rapid summertime warming in the Central Valley in the future.

SO... more energy-efficient and weather-resistant homes could be a good strategy in California's Central Valley!
It's interesting how we take for granted the functionality of a building.  It keeps us warm and dry, right?  Well, when you look closer, you discover that buildings are much more functional than weather shields.  Here is a list of "general satisfaction" factors for an office building survey that are worth considering when you evaluate a building's "value".
 
  • General satisfaction as a workspace
  • Office layout
  • Office furnishings
  • Thermal comfort
  • Air quality
  • Lighting
  • Views
  • Acoustic quality
  • Cleanliness and maintenance
  • Attention and concentration
  • Awareness and communication
  • Interactive behaviors
  • Functionality
  • Acoustic functionality
  • Community
  • Morale and well being
Buildings are functional spaces in which we function.  We work, play, enjoy, relate, learn, listen, build memories, and manage our moods.  With so much riding on a building's functionality not just as a temperate zone of comfort, it stands to reason that we need to look at the toxicity of materials, the amount of seating that encourages conversation, sunshine and views of nature and good ventilation that re-energizes our muscles and lungs.

That's a "system" that embodies green building, sustainable landscape, and social justice all rolled up into one community development strategy.
Building technologies can be more sustainable... or more complicated!  But expertise in design and construction can properly select and install building technologies that reduce energy and other natural resources over the entire life of the building.  The major categories of building technologies that can be incorporated in green buildings include: 

Building Technologies
HVAC&R
Fire & Life Safety
Building Automation and Controls
BAS Technologies
Building Services
