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.
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.
- 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
As with all the other considerations, please do not hesitate to contact us with your specific set of circumstances and challenges
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.
