when electricity and highway networks are out for several days at a time. At building and at community scale, design resilience can maintain safe occupancy conditions when electricity is not available, either from the grid or out-of-diesel on-site generator.
When designs follow best efficiency practices, boilers, chillers, can be smaller, reducing capital cost. Advanced lighting and motors reduce electrical demand. As alternative sources, s
Photosynthetically renewable, the woody biomass is a fuel for heat and cooling (HVAC), service hot water and industrial thermal process systems.
Biomass as a modern
Real estate developers and managers avoided using woody biomass systems; their HVAC engineers and architects could not offer the necessary assurances.
Conditions have changed
for the better.
Equipment has been further improved. Business practices now let building developers and owners get beyond the high capital cost, performance and reliability concerns and uncertainty about fuel supply. Wood chip and pellet boiler performance is reliable and clean, yet the installations use advanced equipment and control systems which are operationally complex.

Economic success is a near-certainty when projects are "qualified."
Qualification is simply confirming that the installation will create a profit as planned and built. The HSC needs to make that decision and guarantee the result under conditions that can be accepted by the facility developer, owner or manager.
