The outdoor data included in this report was recorded at: Anchorage, AK 99503 Outdoor Temperature Test Period Avg: 2/10/10 – 2/17/10 Heating Degree Days Cooling Degree Days 30 ºF 35 0 Outdoor Temperature and Dew Point A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dew point during the test period at the test location. More aggressive temperature setbacks during unoccupied periods may provide energy savings with no impact on occupant comfort. Proper ventilation control and use of an economizer for free cooling may also contribute significantly to energy savings.

The outdoor data included in this report was recorded at: Anchorage, AK 99502 Outdoor Temperature Test Period Avg: 4/20/10 – 4/27/10 Heating Degree Days Cooling Degree Days 39 ºF 26 0 Outdoor Temperature and Dew Point A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dew point during the test period at the test location. More aggressive temperature setbacks during unoccupied periods may provide energy savings with no impact on occupant comfort. Proper ventilation control and use of an economizer for free cooling may also contribute significantly to energy savings.

The outdoor data included in this report was recorded at: Anchorage, AK 99504 Outdoor Temperature Test Period Avg: 4/27/10 – 5/4/10 Heating Degree Days Cooling Degree Days 45 ºF 20 0 Outdoor Temperature and Dew Point A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dew point during the test period at the test location.

The outdoor data included in this report was recorded at: Anchorage, AK 99518 Outdoor Temperature Test Period Avg: 5/4/10 – 5/11/10 Heating Degree Days Cooling Degree Days 49 ºF 16 0 Outdoor Temperature and Dewpoint A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dewpoint during the test period at the test location. More aggressive temperature setbacks during unoccupied periods may provide energy savings with no impact on occupant comfort. Proper ventilation control and use of an economizer for free cooling may also contribute significantly to energy savings.

The outdoor data included in this report was recorded at: Anchorage, AK 99501 Outdoor Temperature Test Period Avg: 5/11/10 – 5/18/10 Heating Degree Days Cooling Degree Days 47 ºF 18 0 Outdoor Temperature and Dew Point A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dew point during the test period at the test location. More aggressive temperature setbacks during unoccupied periods may provide energy savings with no impact on occupant comfort. Proper ventilation control and use of an economizer for free cooling may also contribute significantly to energy savings.

The outdoor data included in this report was recorded at: Anchorage, AK 99508 Outdoor Temperature Test Period Avg: 5/18/10 – 5/25/10 Heating Degree Days Cooling Degree Days 51 ºF 14 0 Outdoor Temperature and Dew Point A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dew point during the test period at the test location. More aggressive temperature setbacks during unoccupied periods may provide energy savings with no impact on occupant comfort. Proper ventilation control and use of an economizer for free cooling may also contribute significantly to energy savings.

The outdoor data included in this report was recorded at: Anchorage, AK 99518 Outdoor Temperature Test Period Avg: 5/25/10 – 6/1/10 Heating Degree Days Cooling Degree Days 62 ºF 3 0 Outdoor Temperature and Dew Point A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dew point during the test period at the test location.

The outdoor data included in this report was recorded at: Anchorage, AK 99518 Outdoor Temperature Test Period Avg: 6/1/10 – 6/8/10 Heating Degree Days Cooling Degree Days 57 ºF 8 0 Outdoor Temperature and Dew Point A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dew point during the test period at the test location. More aggressive temperature setbacks during unoccupied periods may provide energy savings with no impact on occupant comfort. Proper ventilation control and use of an economizer for free cooling may also contribute significantly to energy savings.

The outdoor data included in this report was recorded at: Anchorage, AK 99502 Outdoor Temperature Test Period Avg: 6/8/10 – 6/15/10 Heating Degree Days Cooling Degree Days 56 ºF 9 0 Outdoor Temperature and Dewpoint A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dewpoint during the test period at the test location. More aggressive temperature setbacks during unoccupied periods may provide energy savings with no impact on occupant comfort. Proper ventilation control and use of an economizer for free cooling may also contribute significantly to energy savings.

The outdoor data included in this report was recorded at: Anchorage, AK 99501 Outdoor Temperature Test Period Avg: 6/15/10 – 6/22/10 Heating Degree Days Cooling Degree Days 54 ºF 11 0 Outdoor Temperature and Dew Point A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dew point during the test period at the test location. More aggressive temperature setbacks during unoccupied periods may provide energy savings with no impact on occupant comfort. Proper ventilation control and use of an economizer for free cooling may also contribute significantly to energy savings.

The outdoor data included in this report was recorded at: Anchorage, AK 99518 Outdoor Temperature Test Period Avg: 6/22/10 – 6/29/10 Heating Degree Days Cooling Degree Days 58 ºF 7 0 Outdoor Temperature and Dewpoint A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dewpoint during the test period at the test location. More aggressive temperature setbacks during unoccupied periods may provide energy savings with no impact on occupant comfort. Proper ventilation control and use of an economizer for free cooling may also contribute significantly to energy savings.

The outdoor data included in this report was recorded at: Anchorage, AK 99503 Outdoor Temperature Test Period Avg: 6/29/10 – 7/6/10 Heating Degree Days Cooling Degree Days 58 ºF 7 0 Outdoor Temperature and Dewpoint A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dewpoint during the test period at the test location.

The outdoor data included in this report was recorded at: Anchorage, AK 99501 Outdoor Temperature Test Period Avg: 7/6/10 – 7/13/10 Heating Degree Days Cooling Degree Days 59 ºF 6 0 Outdoor Temperature and Dewpoint A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dewpoint during the test period at the test location. More aggressive temperature setbacks during unoccupied periods may provide energy savings with no impact on occupant comfort. Proper ventilation control and use of an economizer for free cooling may also contribute significantly to energy savings.

The outdoor data included in this report was recorded at: Anchorage, AK 99518 Outdoor Temperature Test Period Avg: 7/13/10 – 7/20/10 Heating Degree Days Cooling Degree Days 60 ºF 5 0 Outdoor Temperature and Dew Point A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dew point during the test period at the test location. More aggressive temperature setbacks during unoccupied periods may provide energy savings with no impact on occupant comfort. Proper ventilation control and use of an economizer for free cooling may also contribute significantly to energy savings.

The outdoor data included in this report was recorded at: Outdoor Temperature Test Period Avg: 7/22/10 – 7/29/10 Heating Degree Days Cooling Degree Days 53 ºF 12 0 Outdoor Temperature and Dewpoint A major factor in the total cost of heating and cooling a building is the heat lost (during heating season) or gained (during cooling season) due to the difference between indoor and outdoor temperatures. The amount of energy consumed to compensate for the difference between outdoor temperature and the desired indoor temperature is driven by three primary factors:  Heat lost or gained due to conduction through walls, ceilings, and windows.  Energy required to heat, cool, and dehumidify outside air entering the building, either through infiltration or mechanical ventilation.  Heat gain due to solar load. This chart shows the outdoor temperature and dewpoint during the test period at the test location. More aggressive temperature setbacks during unoccupied periods may provide energy savings with no impact on occupant comfort. Proper ventilation control and use of an economizer for free cooling may also contribute significantly to energy savings.
