Energy use of prefabricated halls can be very economical
The calculated outdoor temperature -15°C, the calculated indoor temperature +16°C, the middle temperature of the air outdoors 4,6°C, 246 heating days, the operation of 14 hours daily, the radiant heating, the minimal efficiency of the heating system 85%, the fuel is natural gas with a heating capacity of 35,8 MJ/m3.
The insulation option 1: The thermal insulation ABA between two membranes, without any air gap, the heat transfer coefficient is U = 1,8W/m2K

Cover options
Adjustable siding - complete or partial opening - allows adjustment of heating to seasonal needs.
Cover of insulated halls comes in different types: permanent insulated folded cover, sandwich panel or aluminum/glass opening walls.
Sports hall may be heated only when in use
Infra-red radiant heating and heating by electric or gas heaters (suspended from ceiling) are ideal ways of heating areas that are in use. For more information on annual energy consumption please refer to the table.
Return on investment in 5 years
An insulated 18m x 36m tennis hall, used optimally, can bring return on investement in five to six years. Multi-court facilities have lower investment costs and higher revenue due to better commercial use, tournaments, summer tennis schools and such.
Very economical use of lighting
Non-insulated halls, such as riding halls, do not need lighting for most of the day due to high light transmittance through a double membrane of the roof. This is a significant cost saving.
