1
Performance Evaluation of an Installed Insulated Tension System M.J. Augustyniak, T.D. McCoy, T.M. Connell and S. Gellin
2
Dedmon Center, Radford University, Radford, VA USA Original Construction Built 1987 Air supported fabric with liner Fabric coverage: Gym – 4800 m 2 Pool – 560 m 2
3
Problems High energy consumption (air conditioning, supporting the air supported roof) Poor acoustics in the gym; could not use as a multi-use facility Condensation on the pool liner, causing dirt stains
5
New Build Requirements State code required a level of insulation not met by old system (R = 12) (0.47 W/m 2 -°K) New insulated system will maintain the natural daylight In gym, air supported system replaced by a truss support structure with the insulated fabric system as cladding; flexibility required to protect roof supports
6
Properties of New Insulated System Top layer: PTFE coated fiberglass Bottom layer (liner): PTFE coated fiberglass; special vapor barrier for pool
7
Properties of New Insulated System (continued) Inside: Aerogel blanket - Lightest solid material on earth - Hydrophobic - Lowest thermal conductivity of any solid - Translucent - Stable properties - Made from silica - Re-usable
8
Gym: Thermal Performance
9
Gym: Lighting
10
Gym: Acoustical Performance Conventional Construction vs. Tensotherm Roof (Occupied)
11
Pool: Lighting
12
Conclusions Energy costs significantly reduced Lighting more than adequate Acoustic performance in gym allows for multi-function usage Fabric can now compete with conventional roofing systems in cold weather climates!
