Why a Complete HVAC system? 2 Heating and cooling equipment that is: High efficiency. Properly designed and installed. Combined with a duct system that’s insulated, sealed, and balanced. … maintains comfort with less energy. Ventilation systems that remove low-quality air, provide outdoor air, and filter contaminants to improve indoor air quality. 20
HVAC system Checklists 2 Two checklists; one verified by Rater and one verified by the HVAC designer and contractor. Benefits: – Less heating and cooling energy. – Improved comfort. – Improved indoor air quality. – Process control and quality assurance. 21
Heating & Cooling Systems: Putting the “H” and “AC” in “HVAC” 22
Basic heating & cooling system design The amount of heat transfer can be quantified in British Thermal Units (Btu’s). 1 Btu is approximately equal to the energy in a single match. 23
Basic heating & cooling systems design 105F 73F 72F 24 Adding & removing Btu’s impacts the temp. inside the home.
Three major steps to design an HVAC system 25 1) Calculate the heating & cooling load. 2) Select equipment to meet those loads. 3) Design ducts to get air from equipment to rooms, and then back to equipment, to offset loads.
Step 1: Calculate heating & cooling loads 26 Cooling load is the maximum Btu’s added in one hour.
Step 1: Calculate heating & cooling loads 35°F 72°F 27 Heating load is the maximum Btu’s lost in one hour.
Step 2: Select equipment that meets loads 72°F 73°F 28 Select equipment that removes Btu’s to meet cooling load.
Step 2: Select equipment that meets loads Select equipment which adds Btu’s to meet heating load. 72°F 71°F 29
Step 3: Design the duct system Design ducts to properly distribute air through house. This offsets the loads. 30
Value of heating & cooling systems Two components of a complete system: 31 Proper design Proper installation
Value of heating & cooling systems Diagnostic requirements of proper installation include the following tests: – Static Pressure test at the air handler. – Refrigeration test at the outdoor unit. – Electrical Amperage testing. – Duct blaster test. – Room Balancing Test. 32
Ventilation Systems: Putting the “V” in “HVAC” 33
Value of mechanical ventilation & indoor air quality Consumers place value on indoor air quality. Shouldn’t have to sacrifice for energy efficieny This home has high-quality indoor air! This home has low-quality indoor air! 34
EPA’s Indoor airPLUS program Indoor airPLUS is a complementary label for ENERGY STAR certified homes. It addresses consumer demand for healthier indoor environments and offers comprehensive protection against harmful indoor air pollutants - the ‘Gold Standard’ for indoor air quality in new home construction. Indoor airPLUS specifications include contaminant controls, including radon controls, that when added to Version 3 requirements provide a complete energy and indoor air quality home package. Verification can be completed within the ENERGY STAR inspection process. 35
Radon VOC’s Pests How are the ENERGY STAR & Indoor airPLUS programs related? Both are voluntary labeling programs run by EPA. For more information, visit www.epa.gov/indoorairplus/www.epa.gov/indoorairplus/ HVAC Filtration Moisture HVAC Filtration Moisture IAQ Improvement Complete IAQ Protection 36
1.Build the home tight to improve efficiency & comfort. 2.Remove contaminants using occupant-controlled exhaust fan in kitchens & bathrooms and a filter in HVAC system. 3.Bring in outdoor air in a controlled way to dilute contaminants. 4.Include key durability details relating to water management. ENERGY STAR HVAC approach 37
Why a Complete Water Management System? 3 A water management system that keeps the roof, walls, foundation, site, and building materials from getting wet improves durability and indoor air quality. 39
Water Management System Checklist 3 One page verified by the builder during construction. Benefits: – Increased durability. – Improved indoor air quality. 40
Helps prevent durability problems from moisture. Based on code requirements, plus best practices. Especially important in high performance homes, regardless of whether the home is ENERGY STAR certified. Key Points about the Water Management System Checklist 41
The value of checklists You can only expect what you inspect: – Checklists promote consistency. – Ensure full value from investments. 42
The value of checklists Example: A simple medical inspection checklist was developed to reduce infections from intravenous lines. The checklist included five steps; straightforward advice, no new science, nothing controversial. The checklist was used by intensive care units in MI over 18 months. It nearly eliminated intravenous line infections. It saved ~1,500 lives. 43
