Energy saving in a high insulated house in Iran

High (super) insulation is a comparatively cheap method of design and construction that reduces the amount of energy needed to keep interior of a building at a comfortable temperature. In fact, thermal insulating involves three boundaries. Insulating in respect to: 1- Human comfort that determines sanitary boundary. 2- The heat loss of Building components that determines physical boundary. 3- Insulation costs and its amortization at a suitable time that specifies the last boundary and also due to energy rate floating, economical boundary will float too. In this article we consider one story house with two units, total area of 300 m(2) in Tehran, built by local building materials as a case study in three cases: 1- Without thermal insulation 2- Within thermal insulation 3- With high insulation The result shows 53.4% of third case toward second case and 78% compared with first case on energy conservation in building.
