The Centennial State enjoys sunny weather virtually all year round. While it does have its cold winters, they are significantly better with sun, and summers are usually marked with low humidity. But of course, different parts of Colorado still have differing climates given its vast size. The variations result primarily from dissimilarities in terms of terrain and elevation.

In fact, the state features 4 out of the 8 climate zones in the country. Colorado is best known for its mountains. Albeit they only cover a minority of the land area, their presence has a significant impact on the climate of the state.

They can shelter lower areas from adverse weather patterns, as well as air movements. The mountainous areas generally have lower temperatures, thanks to their altitude. Interestingly, the valleys are often cooler compared to the peaks at night because the mass of cool air settles along the former.

During summer, daytime sees comfortably warm weather, while nights remain cool. The Colorado Encyclopedia specified that Eastern Colorado has a uniform climate practically all year round, with plenty of sunshine and limited snow. Despite its semiarid condition, the air remains relatively cool thanks to the low precipitation in the air.

Temperatures in summer reach an average peak of 95 degrees F, while the coldest winters register temperatures as low as minus 15 degrees F. Spring usually sees heavy and frequent rainfalls, although storms are more likely to occur during fall and winter months. Strong winds are also plentiful during winter and spring, which during times of drought can cause dust storms.

Grasses, particularly buffalo and grama grass, are abundant in the Eastern Plains of Colorado. Many cattle farmers have set up base in this area to allow their cows to graze. Many of the lands in this area are mesas and plateaus, and generally at elevations below 7, feet, according to the Denver Channel.

The weather patterns in this far western area are dependent on the orientation of the mountain ranges, the amount of sun, and the amount of air circulating in the different regions.

As such, a higher elevation does not automatically translate to cooler weather, but not as cold as the mountains, although winters may become harsher the higher the area.InspectAPedia tolerates no conflicts of interest.

We include rules of thumb for estimating the necessary BTUs per square foot for cooling or heating a building in each climate zone. Department of Energy. Department of Energy DOE. Watch out : this source does not relate cooling requirements to cooling zones in the U. The US DOE link above provides additional building specifications for each heating zone such as recommended insulation levels.

Tons of ice does not, however, explain an important factor in the comfort produced by air conditioning systems, reduction of indoor humidity - that is, removing water from indoor air. Cool air holds less water in the form of water molecules or gaseous form of H2O than warm air. Think of the warmer air as having more space between the gas molecules for the water molecules to remain suspended.

When we cool the air, we in effect are squeezing the water molecules out of the air. When an air conditioner blows warm humid building air across an evaporator coil in the air handler unit, it is not only cooling the air, it is removing water from that air. Both of these effects, cooler air and drier air, increase the comfort for building occupants.

Note that the BTU rating of an air conditioner itself does not tell you how economically those tons of cooling capacity are being produced. S at Inspect A pedia. Try the search box just below, or if you prefer, post a question or comment in the Comments box below and we will respond promptly.

This version provides variations of the prescriptive maximum SHGC based on the size of a projected overhang and the orientation of the vertical fenestration.

Adoption and enforcement of any new code often occurs into its second or third year of publication, depending on the jurisdiction. The total building performance path allows greater design flexibility but requires detailed energy modeling. Regardless of the chosen compliance path, fenestration must not exceed mandatory air leakage limits.

The IECC requires replacement windows to comply with the requirements set for new construction. The requirements apply whether it is a full window replacement or just sash and glazing replacement.

These requirements are adjusted where shading from permanent projections is provided and for certain daylighting designs. The maximum SHGC can be increased if any permanently attached shading device has a projection factor PF greater than 2. The increase in SHGC is dependent on orientation. Glazing oriented to the north is less than that oriented in the other 3 orientations. In some larger spaces with high ceilings, the code requires a minimum skylight area for daylighting.

Mandatory air leakage limits depend on the fenestration type. For windows, sliding doors and most skylights, the maximum air leakage rate is 0.

Error code: Energy Conservation Code of Pennsylvania.Energy conservation requirements have become a more important issue in the past few years.

The regulations, created by the International Energy Conservation Code, or IECC, is designed to keep buildings as energy-efficient as possible when it comes to heating and cooling. Here is a look at the different insulation and window factors they consider, and the requirements across the eight US climate zones. Each county in the US is sorted by these climate zones, which is sub-categorized by moist, dry, and marine.

R-Values are used to determine the minimum insulative value of different parts of the homes. Insulated ceilings keep heat from escaping out of the top of a building and can prevent damage from ice dams. This is less important in the warmer zones, which have an R-value of 30 in zones and a value of 38 in zones 4 and 5. Zones 6, 7 and 8 have a value requirement of For wood frame walls, the minimum R-Value is 13 in zones Zones 5 and 6 have a requirement of 20, and 7 and 8 are at This is a wall that is made of something other than timber with insulation and drywall.

Brick, stone and concrete are common mass walls, and the width of the material can increase insulative value rather than relying solely on added insulation.

R-values for these walls are lower than hollow timber frame walls, as the wall materials have natural insulative values. Zones 1 and 2 have required values of 3 and 4, Zones 3 and 4 have a required value of 5. Zones 4 marine and 5 have a required value of Zone 6 requires an R-value of 15, and zones 7 and 8 require a value of Floors have a required R-value of 13 in zonesand 19 in zone 4.

From zone 4-marine through 8, the requirements have a condition of at least filling the space if you cannot meet the R-value with the space provided. Requirements for the remaining zones are 30 for 4-marine through 6, and 38 for 7 and 8. Earth serves as a very insulative material, so less insulation is required in many cases in areas that are underground.

All three structures have similar R-values within a region. No insulation is required for zones 1 and 2. Zone 3 requires an R-value of 5 in basements and crawl spaces, but nothing for slabs. Zones 4 and 5 require an R-value of 10 for all three structures. Zones 6, 7 and 8 also have a 10 R-value for slabs and crawl spaces, and of 15 for basements. Windows go the opposite direction when it comes to protection by zone. The U-factor of windows is higher in zones 1 1. Skylights are a bit lower in zones 1 and 2, at 0.

Search for:.Just as we need to wear different outfits in different climates, homes need to be properly designed to meet the temperatures, humidity levels and extreme weather events of their specific climates as well.

Using information gathered from 4, US weather sites, in the early s, the U. It was then divided into three moisture categories designated A, B, and C. As a personal example, I recall a neighbor of mine having to remove 3 large evergreen trees very close to his home that were keeping his home in complete shade.

His home was old and poorly-insulated, so it was heavily subject to weather conditions. His home was often musty and humid he told me, and once the trees came down and the sun was able to reach his home, he was pleasantly surprised to find it less humid and the smell gradually went away.

That is an example of a micro-climate, but also an example of why there are limitations to how accurate the climate zone map can be. And to say a climate zone is based on the temperature and humidity is not the full story; it goes beyond just how hot, cold or humid it is.

You will see that the lines on some climate zone maps are different than on others, and they can also indicate fairly abrupt changes from one climate to the other. The climate regions are described belowwith definitions based on average annual temperatures, heating degree days, and typical levels of annual precipitation. Defined as: any region that receives more than 20 inches 50 cm of precipitation annually and where either or both of the following occur:.

The only subarctic regions in the United States are in found Alaska, which is not shown in Figure 1. In this zone, the month with the most precipitation in the cold season will have three times as much precipitation or more as the month with the least precipitation for the rest of the year. Building America. Zone 8. Very Cold. Zone 7. Zone 5 and 6. Zone 4B. Zone 3B. Homes must be built to meet the challenges of the climate where they standfor reasons of durability as well as energy-efficiency, health and safety.

Homes also need sufficient insulation of the best type and be correctly proportioned for energy-efficiencywhether they are in heating or cooling climates. And homes in any climate should be built to be airtight for reasons of durability to prevent moist air from passing through wallsto reduce energy loss and to safeguard indoor air quality. As for how to build the best walls for high performance homesthat will vary as much as choosing the best winter outfit will vary between Florida and Alaska.

Homes in cold, humid climates require a vapor barrier on the warm side of the insulation to prevent moisture from rotting walls, whereas with air-conditioned homes in Florida, the vapor barrier goes on the outside of walls. If you assemble your wall in the wrong sequence in either climate, it will likely rot in fairly short order.

Then you need to consider the actual building lot where the new home is going. Is it south or north facing, is it surrounded by trees, and if so, are they deciduous or evergreen - as this will effect the insolation of the home - which means how much sun it will get and therefore how much passive solar gain a home can hope for.
