• Calculations - Occupancy and heat gains

    What takes precedence for people gains - is it the Standard room input data, or the definition of activity types? VS. The activity types are referenced below are from this thread: https://communities.bentley.com/products/building/performance/w/building_performance__wiki…

  • CIBSE Gain Queries

    I have turned off infiltration, ventilation, occupants and casual gains from my model to test the solar load portion only. However I still see loads attributed with "Convective" and "Latent" (albeit small). Should these loads exist in my calculation…

  • CIBSE Gain - Temperature rise

    I understand that you get different heat gains in the following scenarios: Within CIBSE gain tool allow temperature to rise by 1degC Within room data increase summer design temp by 1degC There is a calculation procedure for the first scenario…

  • RE: Discrepancies between result table and graph

    Hi Gary - With regards your query, this document should provide you with an answer. Best regards,

  • 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.
