CLIMATE CONSULTANT ANALYSIS

Why is Climate Consultant Important?

As Architects and Designers it is our responsibility to work to design sustainable systems and structures. To do this we need to first understand the local climate. Climate consultant helps us make sense of the data and its effect on built form thorugh easy to understand charts.

TEMPERATURE RANGE

This Temperature Range Chart for Bozeman, Montana shows the Recond High and Low Temperatures and lowest Dry Bulb Temperatures for each month over a full year. In this case, the graph indicates heating/cooling systems are needed at all times of the year to withstain comfort levels. Assigning the proper materiality, glazing systems, and construction methods will be important to ensure climate comfort at the interior of the home.

MONTHLY DINURAL AVERAGES

This chart helps to understand temperature variation. As we can see, humidity fluxuates drastically throughout the year. Humidity, measured through the Wet Bulb mean is highest and furthest from dry bulb in the summer months (June, July, and August). Humidity should be taken in to consideration for moisture control and necesarry heating / cooling systems.

SOLAR SHADING

NORTH / SOUTH FACING

While there isnt any glazing facing directly North or South of the building, thermal comfort and shading is still important. In this diagram, the large hill at 120 feet elevation is shown on the south east side of the property. Incorporating horizontal shading devices at 48 degrees and vertical fins at 23 degrees will efficently block any uncomfortable summer sun.

PSYCHOMETRIC CHART

COMFORT 7.6%

The Psychometric Chart tells us the amount of hours that are comfortable indoors interference is not needed. This location has a 7.6% comfort. This tells us intervention is needed to increase comfort througout the year.

PROPOSED DESIGN (SW)

DESIGN STRATEGY 01: SUN SHADING OF WINDOWS

COMFORT 5.5%

The use of an insulated glazing system will sucessfully deflect excess exterior light and reflect/retain internal heat. This is especially imporant on the South West facade, due to the high amount of glazing

DESIGN STRATEGY 02: HEATING, ADD HUMIDIFICATION IF NEEDED

COMFORT 64.5

Due to the climate, which is below comfort levels for the majority of the year, a strong artifical heating/cooling system in needed to generate a comfortable internal temperature

DESIGN STRATEGY 03:PASSIVE SOLAR DIRECT GAIN LOW MASS

COMFORT 13.1%

Passive sunlight that comes through the windows is especially important and can be maximized per floor plan orientation. This will be helpful on the lower level, where sun can natural heat the interior.
