Simulates passive solar houses by calculating heat losses and solar gains in residential buildings, using interlinked worksheets and very extensive help. Based on New Method 5000, 'solacalc' uses UK climate data to easily and quickly calculate thermal balances and financial analysis. A reference calculation concurrently offers a design comparison without solar features. A Net Present Value calculation provides economic analysis.
