I-REN is hosting a learning session in partnership with ProspectSV to share more about what is driving adoption of natural refrigerant heat pumps for HVAC and DHW uses, outline how current codes apply to this technology, and how to navigate that landscape as it develops. The HVAC industry is in the midst of a technology transition. Electrification and the phasedown of synthetic (HFC) refrigerants are driving natural refrigerant heat pumps, using refrigerants such as CO\u2082 and R-290 (propane), further into use for commercial HVAC and domestic hot water (DHW) applications, and California’s climate goals are accelerating that shift. As this technology becomes more common, Authorities Having Jurisdiction (AHJs) \u2013 building officials, fire marshals, and other local permitting authorities responsible for code compliance \u2013 will need a clear framework for evaluating these systems.<\/p>\n
The session will cover the following:
\n\u25cf Current landscape for natural refrigerants in HVAC
\n\u25cf Benefits and limitations of natural refrigerant systems
\n\u25cf Relevant codes and code application
\n\u25cf Safety considerations
\n\u25cf What to ask for at permit review
\n\u25cf Resources and where to go for support<\/p>","excerpt":"","slug":"i-ren-cs-training-prepare-for-permitting-natural-refrigerant-heat-pumps","image":false,"all_day":false,"start_date":"2026-10-27 09:00:00","start_date_details":{"year":"2026","month":"10","day":"27","hour":"09","minutes":"00","seconds":"00"},"end_date":"2026-10-27 10:30:00","end_date_details":{"year":"2026","month":"10","day":"27","hour":"10","minutes":"30","seconds":"00"},"utc_start_date":"2026-10-27 16:00:00","utc_start_date_details":{"year":"2026","month":"10","day":"27","hour":"16","minutes":"00","seconds":"00"},"utc_end_date":"2026-10-27 17:30:00","utc_end_date_details":{"year":"2026","month":"10","day":"27","hour":"17","minutes":"30","seconds":"00"},"timezone":"America\/Los_Angeles","timezone_abbr":"PDT","cost":"Gratuito","cost_details":{"currency_symbol":"$","currency_code":"USD","currency_position":"prefix","values":["0"]},"website":"https:\/\/docs.google.com\/forms\/d\/e\/1FAIpQLSfqSrr7NKHXjiCWbngLFib_43o-PQ6-M7-I26dfDZQg7BsNEw\/viewform","show_map":true,"show_map_link":true,"hide_from_listings":false,"sticky":false,"featured":false,"categories":[],"tags":[{"name":"contractor event","slug":"contractor-event","term_group":0,"term_taxonomy_id":913,"taxonomy":"post_tag","description":"","parent":0,"count":56,"filter":"raw","term_order":"0","id":913,"urls":{"self":"https:\/\/mcecleanenergy.org\/es\/wp-json\/tribe\/events\/v1\/tags\/913","collection":"https:\/\/mcecleanenergy.org\/es\/wp-json\/tribe\/events\/v1\/tags"}},{"name":"contractor training","slug":"contractor-training","term_group":0,"term_taxonomy_id":930,"taxonomy":"post_tag","description":"","parent":0,"count":38,"filter":"raw","term_order":"0","id":930,"urls":{"self":"https:\/\/mcecleanenergy.org\/es\/wp-json\/tribe\/events\/v1\/tags\/930","collection":"https:\/\/mcecleanenergy.org\/es\/wp-json\/tribe\/events\/v1\/tags"}}],"venue":{"id":13521,"author":"3","status":"publish","date":"2024-03-05 07:06:04","date_utc":"2024-03-05 15:06:04","modified":"2024-03-13 06:46:31","modified_utc":"2024-03-13 13:46:31","url":"https:\/\/mcecleanenergy.org\/es\/lugar\/virtual-event\/","venue":"Virtual Event","slug":"virtual-event","json_ld":{"@type":"Place","name":"Virtual Event","description":"","url":"https:\/\/mcecleanenergy.org\/es\/lugar\/virtual-event\/","address":{"@type":"PostalAddress"},"telephone":"","sameAs":""},"show_map":true,"show_map_link":true,"global_id":"mcecleanenergy.org\/es?id=13521","global_id_lineage":["mcecleanenergy.org\/es?id=13521"]},"organizer":[{"id":90819,"status":"publish","date":"2026-10-05 12:03:34","date_utc":"2026-10-05 19:03:34","modified":"2026-10-05 16:55:26","modified_utc":"2026-10-05 23:55:26","url":"https:\/\/mcecleanenergy.org\/es\/organizador\/i-ren\/","organizer":"I-REN","slug":"i-ren","website":"https:\/\/iren.gov\/","json_ld":{"@type":"Person","name":"I-REN","description":"","url":"https:\/\/iren.gov\/","telephone":"","email":"","sameAs":"https:\/\/iren.gov\/"},"global_id":"mcecleanenergy.org\/es?id=90819","global_id_lineage":["mcecleanenergy.org\/es?id=90819"]}],"custom_fields":[],"json_ld":{"@context":"http:\/\/schema.org","@type":"Event","name":"I-REN C&S Training: Prepare for Permitting: Natural Refrigerant Heat Pumps","description":"<p>I-REN is hosting a learning session in partnership with ProspectSV to share more about what is driving adoption of natural refrigerant heat pumps for HVAC and DHW uses, outline how […]<\/p>\\n","url":"https:\/\/mcecleanenergy.org\/es\/event\/i-ren-cs-training-prepare-for-permitting-natural-refrigerant-heat-pumps\/","eventAttendanceMode":"https:\/\/schema.org\/OfflineEventAttendanceMode","eventStatus":"https:\/\/schema.org\/EventScheduled","startDate":"2026-10-27T09:00:00-07:00","endDate":"2026-10-27T10:30:00-07:00","location":{"@type":"Place","name":"Virtual Event","description":"","url":"https:\/\/mcecleanenergy.org\/es\/lugar\/virtual-event\/","address":{"@type":"PostalAddress"},"telephone":"","sameAs":""},"organizer":{"@type":"Person","name":"I-REN","description":"","url":"https:\/\/iren.gov\/","telephone":"","email":"","sameAs":"https:\/\/iren.gov\/"},"offers":{"@type":"Offer","price":"0","priceCurrency":"USD","url":"https:\/\/mcecleanenergy.org\/es\/event\/i-ren-cs-training-prepare-for-permitting-natural-refrigerant-heat-pumps\/","category":"primary","availability":"inStock","validFrom":"1970-01-01T00:00:00+00:00"},"performer":"Organization"},"is_virtual":false,"virtual_url":null,"virtual_video_source":""}
