What is a blower door?

Blower doors consist of a frame and flexible panel that fit in a doorway, a variable-speed fan, a pressure gauge to measure the pressure differences inside and outside the home, and an airflow manometer and hoses for measuring airflow.

As an energy auditor using blower door tests to help determine a home’s air tightness.

These are some reasons for establishing the proper building tightness:

  1. Reducing energy consumption due to air leakage
  2. Avoiding moisture condensation problems
  3. Avoiding uncomfortable drafts caused by cold air leaking in from the outdoors
  4. Determining how much mechanical ventilation might be needed to provide acceptable indoor air quality

How does it work?

A blower door is a powerful fan that mounts into the frame of an exterior door or window. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings. The test determines the air infiltration rate of a building.

What is a duct blaster?

A duct baster is a smaller fan which is used to directly pressure or de-pressure test the duct system for air leaks; the duct blaster fan is first connected to the duct system at the air handler return grill or main return.  After sealing all supply and return grills the duct blaster is turned on to force air through all duct runs.

The next step would be to increase the fan speed until a standard test pressure is achieved in the duct system (-26 pascal).  An exact leakage measurement is then made using an airflow and pressure gauge connected to the duct blaster system.

Calculations of an estimate of the efficiency loss of the duct leakage can be shown from the leakage measurements. Therefore, it is important to know your duct leakage because it is known that as much as 25% of total house energy loss comes from air infiltration. Not to mention that duct leaks can create air quality problems by pulling pollutants and irritants directly into the house.

Home Ready Inspections performs energy analysis and load calculations now.  If you are need help contact us at 832-661-6154.  

Manual J is the name for a specific protocol (often called “Heat Load Calculation” or “Cooling Load Calculation“) used to determine how much heating/cooling a home needs to stay cool and dry in the summer and warm in the winter. This load calculation process was developed by engineers in the heating and air conditioning industry and has been used for decades to accurately size heating and air-conditioning equipment. After completing this load calculation process, one can choose a properly sized piece of machinery to satisfy the load.

Why is a properly sized HVAC system important?

  • Efficiency: You wouldn’t buy an 18-wheeler just to drive around town, right? That vehicle wouldn’t match the task at hand, and would cost you a lot more money to operate. The same goes for heating and cooling equipment. If your system is larger than necessary, it means that you are paying to operate larger fans and larger compressors. The goal is to buy one that is sized “just right.” This can be equated to highway mileage in a vehicle. If it runs steadily, without stopping and starting, it’s more affordable to operate.
  • Comfort: Contrary to popular belief, bigger is NOT always better. Over-sized air conditioners are not able to dehumidify the air inside the home. Most air conditioning units need to run for ~10 minutes before their coils get cool enough to cause condensation (this is what dehumidifies the air in your home). If the system is oversized, the thermostat will be satisfied before the unit is able to remove any significant amount of moisture. This creates cold, clammy conditions. Properly sized air conditioners should produce relative humidity levels of ~50% in the cooling season (indoor design conditions vary with climate). If your relative humidity is larger than this, you may have an oversized system that is not staying on long enough to properly dehumidify.Heating season comfort is also impacted by over-sized machinery; especially with heat pumps. Why you ask? Because heat pumps produce supply air that is roughly 100 degrees, compared to furnaces that produce supply air that is 125-135 degrees. This means that a heat pump has to move more air around the house in order to deliver a fixed amout of heat. If a heat pump is oversized, this means that there will be more air than necessary moving about the house, creating drafts, and causing comfort complaints. Heat pumps should be sized based on the cooling load of the house (to ensure proper dehumidification), with the rest of the heating needs delivered by the “auxillary” heat – typically electric resistance strip heaters or furnaces.
  • Air quality: If your system is over-sized and therefore not properly dehumidifying, you’ll have moisture problems. This may show up as strange smells, mold or mildew growing in areas that don’t receive much air flow, excessive presence of dust mites, etc. In much of the nation, humidity control is the main purpose of air conditioning systems. In order for them to control this humidity, they MUST be sized properly.

What does a Manual-J Load Calculation report actually provide?
A Manual-J load calculation report provides three main pieces of information regarding heating and cooling load:

  1. Heating Load: This is how much heat your house will require on the almost-coldest day of the year, in the middle of the night (when there’s no help from the sun). This is the number, or load, used to select a piece of heating equipment.
  2. Sensible Cooling Load: This is the amount of sensible heat (the type you measure with a thermometer) that your system should be able to remove on the almost-warmest day of the year, during the daytime (when the sun is heating up the building). This is used, IN COMBINATION WITH the next load-type, to select the cooling equipment.
  3. Latent Cooling Load: This load describes how much moisture your system should be able to remove under “worst-case” conditions. Worst-case for latent loads is typically when it’s hot and wet outside (daytime in the summer).

These three loads are used to select a piece of machinery that fits the loads (heat losses or gains) of your home. When selecting air conditioners or heat pumps, the two cooling loads should be used. And, the selected piece of machinery should be able to supply the proper amount of BOTH latent and sensible cooling, and be less that 15% over-sized, based on the Manual-J load calculation.This will ensure your system is capable of proper dehumidification (assuming the distribution system is performing properly).

Block load calculations versus room-by-room load calculations:
This is an important concept to understand, because it can make all the difference in the performance of your system. Fortunately, it’s an easy concept to describe and understand. It goes something like this:

  • Block Loads: If you imagined your house as one big room, with no walls between rooms and no floors between conditioned levels, this would be your “block.” The block load is telling you what the total heating and cooling loads are for the entire building. As a result, you may be able to select a piece of machinery, but you won’t know how much of that machinery’s capacity is needed in the living room, versus the dining room, versus the bedroom (which is critical information used to properly size the ductwork)
  • Room-by-room Loads: This is a more detailed calculation that tells you the individual loads for each room of the house. This is useful in determining the need for zoning (having multiple thermostats that independently control different areas of the house). However, the most useful aspect of the room-by-room calculation is that it tells you how much air you need in each room. This information can be (and should be) used to determine the size of the ductwork that delivers air throughout the house. This information is also used to “balance,” or fine-tune the airflow to each room after the system is installed. This way, you are ensured that you aren’t getting more or less air than necessary in any given room of the house.

A duct baster is a smaller fan which is used to directly pressure or de-pressure test the duct system for air leaks; the duct blaster fan is first connected to the duct system at the air handler return grill or main return.  After sealing all supply and return grills the duct blaster is turned on to force air through all duct runs.

The next step would be to increase the fan speed until a standard test pressure is achieved in the duct system (-26 pascal).  An exact leakage measurement is then made using an airflow and pressure gauge connected to the duct blaster system.

Calculations of an estimate of the efficiency loss of the duct leakage can be shown from the leakage measurements. Therefore, it is important to know your duct leakage because it is known that as much as 25% of total house energy loss comes from air infiltration. Not to mention that duct leaks can create air quality problems by pulling pollutants and irritants directly into the house.

What is a blower door?

Blower doors consist of a frame and flexible panel that fit in a doorway, a variable-speed fan, a pressure gauge to measure the pressure differences inside and outside the home, and an airflow manometer and hoses for measuring airflow.

As an energy auditor using blower door tests to help determine a home’s air tightness.

These are some reasons for establishing the proper building tightness:

  1. Reducing energy consumption due to air leakage
  2. Avoiding moisture condensation problems
  3. Avoiding uncomfortable drafts caused by cold air leaking in from the outdoors
  4. Determining how much mechanical ventilation might be needed to provide acceptable indoor air quality

How does it work?

A blower door is a powerful fan that mounts into the frame of an exterior door or window. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings. The test determines the air infiltration rate of a building.
