HVAC Refrigerant Leakage Report
An estimated 50% of the powerful greenhouse gases used as refrigerants in HVAC systems leak into the atmosphere. This report details methods to estimate CO2 equivalent emissions from refrigerant leaks and highlights the need to transition to eco-friendly, low-GWP alternatives during HVAC maintenance and replacement.
Peoples Gas and North Shore Gas Custom and New Construction Rebate Program Application
Custom rebates are only made available to help influence and implement projects that otherwise would not be completed, or to complete projects sooner than currently or previously scheduled.
Peoples Gas and North Shore Gas Engineering Study Program Application
The Engineering Study provides customers up to $20,000 to offset the costs of on-site engineering support to perform an implementation study, investment-grade audit or process evaluation required for large custom, capital-intensive energy saving projects
Gas Heat Pump Fact Sheet
Gas heat pumps are an innovative technology that can replace your boiler or furnace.
Commercial Gas Heat Pumps
Commercial gas heat pump (GHP) technologies are highly energy-efficient alternatives to traditional space heating and water heating equipment.
Commercial Gas Heat Pump Installation Considerations
Commercial gas heat pumps (GHPs) are highly energy-efficient technolgy that can be used for space heating, cooling and/or water heating.
Residential Gas Heat Pump Installation Considerations
Residential gas heat pumps (GHP) are a highly energy-efficient technology that can be used for space heating or space and water heating in "combi" applications.
Micro Combined Heat and Power Fact Sheet
Micro combined heat and power (mCHP) systems in the 5–100 kilowatt (kW) range are ideal for building owners seeking cost-effective solutions to save natural gas and electric energy.
Micro Combined Heat and Power Case Study
The Peoples Gas and North Shore Gas Energy Efficiency Programs can work with you to save money on natural gas and electric bills with micro combined heat and power (mCHP).
DOE Packaged CHP eCatalog
The CHP eCatalog is a national searchable web-based catalog that provides engineers with DOE recognized CHP suppliers and technical data for drop-in/packaged CHP systems.
Accelerating Decarbonization with Gas Heat Pumps
Gas heat pumps are an innovative technology that supports equitable decarbonization and grid reliability. They offer superior energy efficiency (over 100%), leading to lower energy bills and significant greenhouse gas reductions. Gas heat pumps also perform well in cold climates and are compatible with existing building infrastructure.
Optimizing Efficiency in Residential Heating Applications
Cold climate performance evaluation of residential heating systems including electric and gas heat pumps. Findings indicate that energy savings, costs, and greenhouse gas reductions can be at odds. In Illinois, gas heat pumps are the most efficient, lowest operating cost, and lowest emission option.
