Properly Venting a Building

Properly venting a building is a critical consideration when planning your building.

Getting rid of the initial ground moisture, quickly, when you have erected your new shelter is something many people do not think of. Quality air changes for plants or animals is something that automatically comes to mind. Getting rid of moisture is equally as important for storing your valuables.

Vent4Since warm air holds moisture and warm air rises, it is important to have venting capacity as high as is possible.

Venting through the roof, with individual turbines or a continuous roof vent, is the most effective but also the most costly.

This is only really necessary when you are in a very protected spot and there is a real need to keep the temperature down in a long building.

vent3Most medium length buildings that have the ends facing into the prevailing winds, can be adequately vented with gable end peak vents.

  • Make sure that these openings are as big as possible and as high as possible.
  • It is also important to make sure your “windows” can withstand the winds in your area.

Our centre pivoting gable vent has filled this requirement very effectively.

  • With part of the window going in and part of it going out, the wind can never get hold of it.
  • With the top and bottom rope through a double pully on the ridge, it is easy to maintain precise control over the opening area

Livestock Shelter Benefits

Animals thrive in a greenhouse type environment benefiting from being dry, and being out of the wind and in the light, without being in the direct sun. The cushion of air created by the inflator fan will reduce the condensation. Roll up sides are added for easy natural ventilation. Usually customers attach a snow fence or netting to the inside of the arch if the structure is mounted to the ground, so the animals do not come in contact with the cover or run away when the sides are rolled up. A short wall is also an option to keep the animals away from the plastic while also increasing the sidewall height. A white tarp covering may be used instead of the double white poly, especially in situations where the animals are going in and out on their own accord when they require shelter.

Greenhouses 101: Orientation and Location

The location and orientation of a structure are two different things that need to be given careful thought to since the consequences are so long lasting. The cost of making changes after the fact are significant and often make it impossible. You should never put a structure somewhere simply because the area is not good for anything else. Location is more about what you need and orientation has to do with what the structure needs to perform well.

Location has to do with accessibility to power, water and handling the product that the structure shelters. If bringing in water, electricity or a driveway is too costly for the budget at present, you will have to start weighing cost versus benefit. This can only be accurately done if you understand the requirements, choices and consequences. Drainage, ventilation and light requirements are also important considerations which change from location to location.

Orientation has to do with a structure being north/south, east/west, or somewhere in between. This will have an impact on ventilation, light, snow shedding and lay of the land. For all of these things you need to have a good handle on what the structure needs to perform well. A structure must be level from side to side to shed snow well but can have some slope from end to end. Ventilation is easier when a structure is inline with the prevailing winds but you do get more sunshine in the building if it is north/south.

Greenhouses 101: Knowing the Basics Before you Buy

Knowing the basics when you are starting the process of purchasing a shelter includes having a firm handle on what you are trying to accomplish and what you are dealing with. This applies for both greenhouses or storage structures. By efficiently choosing from all of our structure choices in combination with your goals and the restrictions or challenges in the best possible way, you will be creating a structure package that is going to serve you well for years to come.

Structure choices include not only size and profile but many choices of coverings. Anchoring choices will be determined by soil conditions and the possibility of relocating the building. Ventilation requirements will impact which structure package you choose. Size, spacing and shape of the hoops will allow you to effectively deal with the weather in your location.

Your goals will need to be specifically spelled out and will likely be modified once the realities of some of the obstacles have been determined. Goals should always include both short and long term plans since some structures and layouts are easier to expand then others.

Restrictions or challenges are not just limited to wind, snow load and other climatic issues. Accessibility of water, power, roadways and market opportunities will impact where and what you can or should build. As each of these parts are researched and developed, they will be impacted by the reality of your budget. By knowing your options, you will be able to get best value for your investment

Roll Up Side Wall Considerations

Ventilation can either be done passively through openings or mechanically with fans. Roll up sides are an economical way of getting lots of air movement since no electricity is required. Roll up sides become even more effective when used on longer buildings. Roll up sidewalls are often used in combination with a small exhaust fan for early and late season ventilation when opening the sides is not practical.

If a structure is very exposed, it is best not to open more then 3’ in height due to potential of wind damage. If a structure is extremely sheltered, it is best to go even up to 6’ to create maximum opening. Roll up sidewalls are most effective when used in combination with peak end wall vents to create a “chimney effect” to draw warm air out of the building, especially when it is very calm. These vents are effective for air movement when outside temperature does not allow opening of the sides.

When a structure has a low profile, you will need to be careful during rainy periods due to moisture getting into the structure area. High profile structures (with straighter walls) usually work better with roll up sidewalls. When preventing a floor draft is an issue, the roll up mechanism can be raised and then the structure is lined with a skirt for the bottom 2’-3’. When using this method of ventilation, it should always be done on both sides. An effective use of this method includes opening the “downwind side totally and the opposite side on marginally.
