Method and apparatus for building environmental compliance
DCFirst Claim
1. A building environmental compliance apparatus comprising, in combination:
- at least one remote data collection point, said data collection point containing at least two environmental condition sensors, wherein said remote data collection point replaces an existing thermostat;
a data logging point communicating with at least one remote data collection point, said data logging point storing historical environmental data from remote data collection points;
a set of data polling intervals, each member of said set unique to at least one remote data collection point, whereby said data logging point stores data from remote data collection points according to said data polling intervals.

Abstract
A method and apparatus for replacing existing thermostats in buildings with physically small, inexpensive sensor array units that gather local environmental data such as temperature, humidity, carbon dioxide concentration, motion, particulate matter concentration, possibly toxic gas presence, and other parameters. The local arrays report data back over existing building wiring including thermostat wires and building power to a central data logging node. The central data logging node stores and reduces data for reporting over to a computer over a conventional RS-232 link. The data is used to prove compliance with environmental and safety regulations and requirements.
