Abstract: Methods and systems for reducing combustion emissions generated in, or released from, a combustion chamber are provided. Systems and methods provided herein may be used to modify, for example, an existing fireplace such that combustion emissions resulting from burning a fuel combustion source are reduced. The method involves providing an emission reduction system which includes a casing assembly with at least one panel of a catalyst-coated media and a support structure supporting the casing assembly. The casing assembly is positioned between a fuel combustion source and a flue by associating the support structure with an interior surface of the firebox. The fuel combustion source is burned to create a fire, such that the catalyst-coated media reduces emissions associated with fuel combustion when contacted with combustion exhaust.

Abstract: A control circuit accesses information regarding at least (1) listing events for real estate offerings other than a given real estate offering (for which the control circuit is assessing a corresponding listing price) and (2) offering particulars for real estate offerings other than the given real estate offering. The control circuit compares that information with listing events and offering particulars of the given real estate offering to generate a plurality of corresponding relative evaluation metrics for the given real estate offering and then aggregates that plurality of corresponding relative evaluation metrics to generate a corresponding characterization of the listing price for the given real estate offering.
