Air Source Heat Pump Non-residential Component

class aaem.components.ashp_non_res.component.ASHPNonResidential(community_data, forecast, diag=None, prerequisites={})

Bases: aaem.components.ashp_base.component.ASHPBase

Non-Residential ASHP component of the Alaska Affordable Energy Model: This model estimates the potential reduction in heating fuel use from installation of Air Source Heat Pumps in Non-residential buildings. Reduction in fuel used is based on coefficient of power in hypothetical ASHP system and heat energy produced per year. Savings result from differential heating fuel costs and ASHP operation costs. The cost of the ASHP infrastructure projects are based on the number of non-residential buildings in the community and the cost of AHSP systems themselves.

Parameters:

community_data : CommunityData

CommunityData Object for a community

forecast : Forecast

forecast for a community

diagnostics : diagnostics, optional

diagnostics for tracking error/warning messages

prerequisites : dictionary of components, optional

‘Non-residential Energy Efficiency’ component is a required prerequisite for this component
