Very high CIBSE Solar Gains
I modelled a simple 5mx5m glass box with no heat transfer across the floor or ceiling and I created a custom glass to replicate a Pilkington glass (U-Value of 0.6 and g-factor of 0.55). When I checked the solar gains using CIBSE Gains they were 10.8kW…
RE: CIBSE Gain - Results Breakdown
Matthew, you have probably turned on Temperature Rise in the Design Data tab. When you use Temperature Rise the individual loads are combined in the underlying equations and cannot be accurately split out afterwards.
