WHOLISTIC ENGINEERING
  • 2020 ENGINEERINGs approach for problem solving

3
WHOLISTIC ENGINEERINGDefinition
Wholistic Engineering is a management approach
which includes the comprehensive inclusion of all
issues and possible conditions related to the
primary task or mission
Wholistic relating to a complete and total
system or organization of parts fitting or
working together as one. A system, which may
also exist within a whole system, includes a
group of units or method of procedure so combined
as to form a functioning whole and operating in
unison an organized whole. Engineering a
science by which the resources and properties of
matter and sources of energy are made useful to
humankind in systems, structures, machines, and
products.
4
WHOLISTIC ENGINEERING
  • Its all about relationships

5
WHOLISTIC ENGINEERINGDesign Approach
  • Whole System Design
  • Site Relationships
  • Integrated Design
  • Design Relationships
  • Sustainable Design
  • Materials Resources

6
WHOLISTIC ENGINEERING
  • 3-Point design criteria for evaluating solutions
  • Economical (short-term and long-term costs)
  • Environmentally Friendly (ecologically
    compatible)
  • Simple (easy to build and operate)

7
WHOLISTIC ENGINEERINGleads to
  • Ecological / Ecosystem Based Solutions
  • Mimic Natural Systems
  • Eliminate the Problem/Root Cause
    vs.
  • Treat the Problem/Symptom

8
Sustainable Infrastructure Strategies
  • Changes to site development methods
  • Learning from our past failures and successes

9
Stormwater Detention
  • Standard Conventional Design
  • Create Pond with outlet control
  • (End of the pipe solution)
  • Do they have to be this ugly???

10
Impervious Surfaces
Sustainable Infrastructure Strategies
  • As impervious
  • surface increases...
  • Peak run-off velocities increase, base flows
    decrease, evapotranspiration decreases
  • Erosion happens and streams have no water

Sustainable Design Principles
  • Mimic Natural Systems
  • Net Zero Impervious Surfaces
  • Minimize Earthwork
  • No Curb Gutters or Catch Basins
  • (Do not concentrate stormwater flows!)
  • Roadways and Walkways shall be porous surfaces
  • Use Impervious Surfaces for beneficial uses
  • (i.e., Rainwater Harvesting, Vegetated Roofs)
  • Landscape areas used for Stormwater Management
  • (i.e., Raingardens)

  • Uses plantings in a conditioned planting soil
    bed to treat and manage stormwater runoff

26
Soil Amendments(Compost Amended Soil)
  • Amended Soil Ground Cover
  • Sand/Organic blend placed over disturbed yard
    areas to restore on-site water holding capacity
    and provide healthy plant growing media.
  • Amended soil mixes may include sand,
    topsoil
  • and/or Grade A compost.

27
Rainwater Harvesting
  • LID - Stormwater Management Technique - Options
    for potable and non-potable water uses -
    Non-potable uses include toilet flush, laundry,
    and irrigation

Islandwood Cisterns for irrigation of organic
gardens
28
Rainwater Collection and Reuse
  • Use impervious roof surfaces for beneficial uses
  • Irrigation Only
  • Toilet Flush Water
  • Potable Water

29
Green Roofs
  • Types of Green Roofs
  • Extensive
  • Intensive
  • Underground Parking Garages Earth
    Shelter Buildings

Underground Parking Midrid, Spain
30
Green Roofs
  • Ecological Benefits
  • Cleansing of airborne toxins
  • Re-oxygenates the air (carbon sink)
  • Recycling of nutrients
  • Reduction of the Urban Heat Island effect
  • Technical Benefits...
  • Reduces temperature extremes on the roof
  • Prevents mechanical damage to the roof 
  • Reduces noise transmission into the building
  • Increased energy efficiency
  • Stormwater Management
  • Owner Benefits...
  • Additional Usable Space for tenants
  • Lowers maintenance and replacement cost

31
Green Roofs
  • Extensive Green Roofs
  • Lightweight systems of thin layers of drought
    tolerant self-seeding vegetated roof covers using
    colorful sedums, grasses, mosses and meadow
    flowers requiring little or no irrigation,
    fertilization or maintenance.
  • Can be constructed on roofs with slopes up to
    33, and can be retrofitted onto existing
    structures with little, or most often, no
    additional structural support.

32
Green Roofs
  • Intensive Green Roofs
  • more elaborately designed roof landscapes, such
    as roof gardens, that are intended for human
    interaction and need to be engineered to conform
    to the load requirements. 
  • Typically have flat roof surfaces or slopes of up
    to 3.

shortcomings of conventional water carriage
sanitation
ecosan principles
  • Unsatisfactory purification or uncontrolled
    discharge of more than 90 of wastewater
    worldwide
  • Severe water pollution, unbearable health risks
  • Consumption of precious water for transport of
    waste
  • High investment, energy, operating and
    maintenance costs
  • Frequent subsidization of prosperous areas and
    neglect of poorer settlements
  • Loss of valuable nutrients and trace elements
    contained in excrements due to discharge into
    waters
  • Problems with contaminated sewage sludge in
    combined, central systems
  • Linear end-of-pipe technology

wastewater and excreta are a valuable resource
ecosan principles
  • farmers around the world yearly require 135 Mio
    tons of mineral fertiliser for their crops, while
    at the same time conventional sanitation dumps 50
    Mio tons of fertiliser equivalents from so called
    wastewater flows into our water bodies -
    nutrients with a market value of around 15
    Billion US dollars.
