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.
We at Multi Shelter Solutions are proud to be associated with the Canadian Organic Growing Community. Through events such as the Guelph Organic Conference, which Norm speaks and MSS exhibits, the ACORN Conference on the East Coast, and our new membership in the Eco Farmers Association joining their show, we are able to stay connected with up to date information, as well as having that face to face connection with the members of the Organic Community. We have been fortunate to partner with Jean-Martin Fortier, Bethany Acres and Abundant Acres to be part of educational workshops as well. We are pleased to be working on continued improvements in our product offerings to help match the growing interest and demand of today’s culture and trends.
We hope you are able to get involved with one of the many Organic Week 2015 events happening near you. There’s still 4 more days to enjoy the many samples, farm tours, workshops and information seminars in your community. Canada’s National Organic Week is the largest annual celebration of organic food, farming and products across the country. See the link for more events and information!
