SUMMARY:Retrofitting Crawlspaces for Health\, Moisture Management\, and Wildfire Safety
DESCRIPTION:Many existing crawlspaces require remediation prior to other energy upgrade work in the house can proceed\, including attic or electrification upgrades. This course examines retrofits of vented and unvented crawlspaces\, the tradeoffs between each crawlspace assembly and the crawlspace assembly’s impact on the home’s overall performance and comfort.  From home durability to occupant safety and comfort\, Dan Perunko of Balance Point Home Performance will address moisture and vapor sources\, rodent control\, as well as strategies to reduce wildfire ember intrusion.

SUMMARY:Air Sealing New and Retrofit Construction
DESCRIPTION:Designing and constructing airtight houses and buildings allows for projects that need less heating and cooling. As a result\, it is less costly to attain zero carbon as proper air sealing saves energy and results in smaller mechanical equipment. Achieving super airtight assemblies is about the correct mind set as well as proper protocol and materials. This class will allow you to acquire the knowledge and skills needed to achieve your project’s air sealing goals. Terry Nordbye will demonstrate step by step procedures and materials to air seal a new construction house\, including Passive House\, to virtually any airtightness and achieve deep reductions in retrofit work. You will be shown all steps from planning to construction and learn why\, where\, and when to air seal.

SUMMARY:Balanced Ventilation for Better Health\, Comfort\, and Energy Efficiency: System Types\, Install Strategies\, Duct Design and Critical Details
DESCRIPTION:More buildings are being constructed with high-performance building envelopes. For these buildings\, a well-designed and installed air quality system is a must. In this class we will look at performance-based design and installation practices that lead to effective ventilation and filtration systems. Examples of completed\, high-efficiency systems are presented to show how they were built and commissioned\, with instructor Dan Perunko of Balance Point Home Performance sharing lessons learned so others can avoid repeating them. \nAgenda: \n\nIntroduction and safety message\nEquipment selection criteria: Energy Recovery Ventilator (ERV) or Heat Recover Ventilator (HRV)\nHeat recovery cores and their efficiencies\nFan motor types\nFan motor power and install issues that increase power consumption\nIntegrated with HVAC vs stand alone systems\nControl strategies\nLocating the system to maximize performance\nProper ducting for ventilation systems\nDuct materials – where to use metal\nHow to size ducts for low static systems\nDuct layout options\nOutside Intake and exhaust grills\nEmber and smoke intrusion\nRoom intake and exhaust grills\nGrill sizing and sound\nFilters\, how many\, how big and where do we need them\nLow energy\, high efficacy\, recirculating air filter\nCommissioning balanced ventilation systems\nMeasuring system energy performance\nMeasuring effective heat recovery
