More Than Zero

More than zero creates more energy than it consumes. It reduces our carbon footprint, and sequesters carbon from the atmosphere.  It preserves our potable water resources, and cleans our watersheds.  It eliminates waste by making our system discharges inputs for other processes. We want to have a positive impact on the environment, by achieving more than zero.

The path to net zero is a 10 step process:

  1. 1. Define the zero you are seeking (energy, carbon, water, waste or cost).
    As an example, a zero-energy goal would proceed as follows:
  2. Establish the design criteria for system performance (source energy, site, energy, etc.).
  3. Understand the microclimate of the project site.
  4. Design the siting, form, and mass of the building to maximize the use of natural energy flows and reduce external loads to the absolute practical minimum.
  5. Minimize lighting energy use through effective daylighting.
  6. Reduce plug loads as far as possible.
  7. Employ extremely efficient HVAC systems to handle the remaining loads (including natural ventilation and mixed mode where feasible).
  8. Develop accurate predictions of annual building energy consumption.
  9. Provide renewable energy systems to offset resulting energy use.
  10. Commission your systems and ensure proper hand-over to O&M staff.
