  5. 5. Why Super Insulation ?Why Super Insulation ? • No leaky buckets – conserve the energy that is  inside the buildinginside the building. • No need to recreate – Heating and cooling  ievery time. • Recycled –Heating & Cooling. • Use of latent –heat and cold.
  6. 6. Super Insulation.
  7. 7. Why TABS ?Why TABS ? • TABS – designed buildings use Radiant Liquid g g q based –Heating and Cooling. • Water is 3500 times more efficient than “forced  air systems”air systems” • Space Conditioning –Redefined. • No boilers / chillers / VRVs• No boilers / chillers / VRVs • No necessity for “expensive BMS Controls”. • No “ Suspended Ceilings”No   Suspended Ceilings • No real maintenance. • Cheaper CAPEX cost and OPEX cost.p
