"Our Common Future"

In 1987, the United Nations released the Brundtland Report, which defines sustainable development as "development which meets the needs of the present without compromising the ability of future generations to meet their own needs".

Seven generation sustainability is an ecological concept that urges the current generation of humans to live sustainably and work for the benefit of the seventh generation into the future. It originated with the Iroquois - Great Law of the Iroquois

KEC Google Maps

Its official.  Google's imaging satellites have flown over recently.  It looks like this was late winter / early spring.  This shot shows the building and the PV array.


KEC Week 60


With 26 work days remaining the focus is on finishes, equipment start-up, commissioning, and punchlist.  The site will remain busy right up to the completion however we are well positioned for a strong completion.

KEC Passive Design




General Guidelines to Consider for Passive Design include:
Site conditions and solar orientation play a major role in siting a location.  Consider the following:
  – Natural vegetation
  – Water run-off
  – Seasonal water tables
  – Solar orientation has a major effect on comfort and energy use
**note the image above was from an Australian website so for US, replace "north" with "south"


Room layout should take into account how and when rooms will be used and how this impacts:
  – Natural daylighting opportunities
  – Natural ventilation opportunities
  – Passive solar heating
  – Sun shading, vegetative shading


Orient the structure so south wall faces within 30 degrees of true south
  - In rooms on S side, windows should equal 8-12% of floor area
  - Shade S windows from summer sun
  - Use casement windows on walls facing prevailing winds to scoop air for natural ventilation
  - Locate rooms to take advantage of natural light and heat based on time of use

Use stormwater management such as peremeter drains, gutters, subsurface drains to address rainfall and groundwater


Glazing
  - Keep in mind more glass equals less lighting
  - South facing windows should have high solar heat gain to allow light in
  - East and West windows should have low-gain to reject summer sun
  - North windows should have lowest U-value


One of the primary goals of the KEC is to be a Net Zero Energy facility.  All the energy used in a year must also be produced onsite.  The energy source for the KEC is its PV array.  Since the up front cost of PV is fairly expensive, the goal in designing the facility is to make it as efficient as possible.  Therefore Passive Design techniques were used to reduce the energy consumption and up front PV costs.

The KEC implemented the following Passive Strategies:
  - Building siting to optimize southern exposure
  - High performance envelop - R44 walls and roof assemblies achieved with spray insulation and SIPS panels
  - Shading with vegetation and sunshade to reject summer sun
  - Natural ventilation with operable vents on the lower window units and on upper clerestories to draw air movement through the space as well as Earth Duct to pre-condition fresh outside air
  - Thermal bridging - all exterior walls are double framed with an air space between framing

KEC Week 57


April saw sheetrock tape sand and prime progress through the building.  The Elevator installation went very smooth.  Flooring and millwork was in full swing.  We started commissioning meetings and put together a start-up testing balancing and commissioning schedule to ensure a smooth completion.  We added a dedicated resource to start the work to complete list for all rooms in the building as part of a pre-punchlist process.  The schedule continues to track very well to the original completion date.

Looking ahead at May we will begin our equipment start-ups and systems balancing.  Commissioning meetings will continue.  Millwork and flooring will continue.  Finish paint will follow.
