Viridescent Building
Net Positive Passive House
General Energy Use, Strategies and Systems
Energy Use:
--Passive solar design principles (southern glazing, shading devices, high performance triple pane windows, thermal mass)
--Ductless mini-split heat pumps with hyper heat
--Air Pohoda iERV (90% efficient with air-flow variability within the core with an ERV filter and an HRV filter available). It also comes with its own web portal that reports fan speed, incoming air temperature, exhausting temperature, and humidity for both in coming and exhaust air.
--very compact plumbing core
--Combustion free, zero emissions building.
--19.4 KW PV solar array
--EV charging station available to the public.
--All LED lighting
Energy Strategies:
The basic energy strategies for this building common tried and true practices for passive houses and Net zero buildings everywhere:
--Reduce energy demand by employing passive solar principles witha simple volume (and with high performing windows)
--Reduce demand by designing a robust, high-performance building envelope (very tightly sealed and very well insulated)
--Reduce the size of the mechanical system, and use a highly efficient mechanical system to provide heating and cooling.
--Provide a balanced ventilation system.
--Provide renewable energy to provide for the remaining building energy needs.

Datasets and utility bills sources and reliability: This building will begin tracking its energy usage circuit by circuit at the beginning of 2016 with an energy monitoring system. It will be highly reliable and accurate. We plan to make this information available to NESEA and it will be updated monthly within the first year, quarterly within the second year, and annually thereafter.
