Everything in our environment is connected. No action goes without consequence; every action is felt by any number of links in the
environmental chain. While the initial effects of our development and advancement felt by our civilization are minimal, the impact on
other species and habitats can be immediate and life threatening. We are living in an age where the impact of the combined negligence
of our and previous generations is alarmingly evident; we can no longer deny we are dangerously approaching a tipping point in the
future of our natural environment.
Where are our priorities?
Should we continue to
ignore the cost to the
environment in favor of
saving money in the short
term, or work solely for
the environment with
no regard for profit? Is
there a solution that
is both profitable and

The United States has become too reliant on foreign nations for natural gas due to our ever increasing consumption of energy. This structure
was predicated on the availability of cheap energy, which is no longer the reality. The United States must become more stable in its energy
needs in order to maintain its position as a world power.

solar radiation and Thermal Storage Capacity
The ground has an immense capacity
to equalize temperature and retain heat.
The map above (and overlaid upon the
map to the left) marks the temperature
sustained just a few feet beneath the
top of the soil.
Imagine a system that could utilize
this temperature as a starting point
to reaching the desired comfort zone
instead of beginning from the fluctuating
The map above marks how much solar radiation is attained daily by different regions across th US, ranging from 1.25 kWh/m2/day in parts of
Alaska, to over 8 kWh/m2/day in Southern California.
The ISOMAX system requires 250 kWh/m2 of solar radiation to run annually. That equals 0.69 2
kWh/m /day. This is distinct from
the total energy consumption of the system; this number represents the the solar radiation that the system relys on.
The map above shows that the conditions with the least sunlight in Pennsylvania still get 2.81 kWh/m2/day, four times the energy
needed to power the system. Even the northernmost parts of Alaska recieve almost twice as much as they would need, recieving energy
directly from the sun at a rate of 1.20 kWh/m2/day.

Insulated Concrete Forms
ICF construction begins with stay-in-place Styrofoam. Rebar is placed within each unit and concrete is poured inside to make a
permanent structure. The end result is a high-performance, structurally sound wall that is already insulated, has a vapor barrier, and
can receive final finishes to the interior and exterior portion of it.
Advantages of ICF:
Increases energy efficiency
Reduced noise transmission
Reduces CO2 emissions
Reduces waste for land fills
Reduces construction time
Replaces insulation material
No structural deterioration
Building with ICF improves the envelope and
the thermodynamics of every structure. Energy
savings of between 30%-70% are realized
in the US, whether it is in Alaska or Florida,
Arizona or New York.

Statistics pulled from the Energy Information Administration Annual Report, 2005 and extrapolated to find the average square footage
per US residence and energy consumption data.
Calculations prove the overall energy savings to the customer to be 51% - 55% for the entire US and 60%
- 64% for the North East. These numbers reflect the actual utility bill including the cost of appliances, lighting, and refrigerator
- none of which are provided for by this system. The actual savings from heating, air-conditioning, and the heating of water can be
seen to be between 84% - 92% as the US average and 90% - 95% in the North East.
Projected Global Impact
60% of energy expenditures in the US come from heating, cooling, and ventilation of our buildings. Imagine the
difference it would make if all buildings implemented this system and we could eliminate this cost to our economy
and to our environment. We would be leaders on a global scale, pioneering change for future generations, and
without any compromise in our standard of living.

Energy Reconsidered is going to pull profits from a range of areas in the industry: sublicensing, distribution,
consultation, and construction supervision. The ISOMAX building system presented here is potentially just the
beginning of product lines offered by Energy Reconsidered through continued research and development inside of
our direct engagement with Edmond Krecké.
This building system yields results to varied typologies within the building industry including new construction as
well as retrofitting existing projects. We have identified several potential projects to go forward with in the next
year, including typologies such as single family homes, dorm style, multi-unit condos, low-income multi-unit,
assisted living, co-housing development, as well as office towers. Our current prospective client list includes
Habitat for Humanity, the Philadelphia School District, and Temple University.
