Base House Info

This section will show you information on your as designed house. Reviewing this section carefully before selecting upgrades will help reduce sorting results on the Reports Page when looking at results to help reach your performance target.

House Title

• Once your file has loaded you can mouse over the House Info and Simulation Info and see additional info

House Info

• A list of Base House assemblies and details is listed here.
• This can be referenced from any page on the HEET app and is especially useful when selecting upgrades.

Simulation Info

• A list of all previous upgrades explored on the file are listed here.

Step Info

• This section displays which Performance Step the Base House currently complies with.
• Your Step is a combination of 3 factors: TEDI/%TEDI, MEUI/%MEUI, and ACH/NLA/NLR and is dictated by the worst of these 3 elements.
• GHGI is a metric being proposed at a provincial level and may be adopted by some municipalities.
• HEET will automatically select the option that is best for your house. The metric selected will be the one closest to the next Step.
• The metric to the left of the green line is the metric being used to determine compliance.
• If you are looking to improve the performance of your house, staring with the metric with the lowest score is a good strategy.

Where Your Home is Losing Heat

• This chart breaks down where your home is losing heat into 7 categories.
• HEET will give you additional details regarding the elements have the greatest effect on the category.
• Mousing over each of the the elements in the large bars will display the energy conservation measure and how much it is affecting the category.
• Categories with the largest heat loss are a good place to start to improve your TEDI.
• The smaller, lighter bars represent the Reference House.
• If you are using the Reference Metrics for compliance, you can compare the 2 bar graphs to identify which categories should be focused on to reduce the Base House heat loss to be lower than the Reference House heat loss.
• The number inside the pie chart shows the total annual heat loss.

Where Your Home is Using Energy

• This chart breaks down where your home is using energy into 6 categories.
• HEET will give you additional details regarding the elements have the greatest effect on the category.
• Mousing over each of the the elements in the large bars will display the energy conservation measure and how much it is affecting the category.
• Categories with the largest energy use are a good place to start to improve your MEUI.
• Additional Baseloads and Lighting and Appliances are currently set by Hot2000 and cannot be changed in HEET.
• The smaller, lighter bars represent the Reference House.
• If you are using the Reference Metrics for compliance, you can compare the 2 bar graphs to identify which categories should be focused on to reduce the Base House heat loss to be lower than the Reference House heat loss.
• The number inside the pie chart shows the total annual energy consumption.

Air Leakage Comparison

• Air leakage is the only metric that EAs can input into Hot2000.
• This graph compares NLA, NRL, and ACH and converts them to ACH.
• The black dotted line represents the Base House.
• Mousing over the bar graphs will display the ACH equivalent for each air tightness metric for the corresponding Step.

GHG Emissions

• This chart shows your house's GHG emissions relative to all of the houses in HEET.
• Mousing over each bar will display additional info regarding the specifics of houses that comply with that GHG level.
• The median performance metrics for the houses in the highlighted GHG range are indicated.
• Within each GHG range HVA types are listed.
• The percentage displayed represents the relative number of homes for each HVAC type in the associated range.

Window Display

• The Window Distribution graph shows the total window orientation distribution for the house.
• Mousing over each piece of the pie will give addition information on the windows including area and % of overall glazing.
• Window orientation has significant impact on TEDI.
• South facing glazing typically improves your TEDI but runs the risk of overheating and increasing the cooling load if there is improper overhang design, improper SHGC, or improper ventilation in the rooms with lots of glazing.
• North facing glazing typically negatively impacts TEDI.
• The Window Heatgain and Window Heatloss graphs display the distribution of heat transfer through the windows of the house.
• Houses with lots of North facing glazing may need a combination of thermal upgrades to improve TEDI.
• Increasing the SHGC can reduce the heating load but will increase the need for cooling.

Where Your Home is Losing Heat

• This graph displays the modeled thermal loads of the house over a period of 1 year.
• Improving envelope performance typically includes increasing solar gains, increasing internal gains, decreasing thermal losses, or a combination of all 3.
