Value of a Complete

HVAC System

why a complete hvac system
Why a Complete HVAC system?
  • 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.

hvac system checklists
HVAC system Checklists
  • 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.

basic heating cooling system design
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.

three major steps to design an hvac system
Three major steps to design an HVAC system

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.

25

step 1 calculate heating cooling loads
Step 1:Calculate heating & cooling loads
  • Cooling load is the maximum Btu’s added in one hour.

26

step 3 design the duct system
Step 3:Design the duct system
  • Design ducts to properly distribute air through house. This offsets the loads.

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.

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 low-quality indoor air!

This home has high-quality indoor air!

epa s indoor airplus program
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.

ENERGY STAR HVAC approach
  • Build the home tight to improve efficiency & comfort.
  • Remove contaminants using occupant-controlled exhaust fan in kitchens & bathrooms and a filter in HVAC system.
  • Bring in outdoor air in a controlled way to dilute contaminants.
  • Include key durability details relating to water management.

Key Points about the Water Management System Checklist
  • 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.

the value of checklists
The value of checklists
  • You can only expect what you inspect:
    • Checklists promote consistency.
    • Ensure full value from investments.

the value of checklists1
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.
