Once the Building Model has been completed the results for heat gains and losses to the space can be considered as well as the Summertime temperatures based on engineering assumptions made by the engineer. For example, the engineer can analyse the effect of pre-cooling the air to the space and the effect this has on any potential plant requirement. The engineer can also experiment with different glazing types and configurations to offer the optimum solution whether it be via natural infiltration, pre-cooled air or full air conditioning.
Heat gain calcs
Summertime temperatures in the spaces can be determined under various conditions.
The building model is a wholly dynamic model where room temperature profiles and room positions interact to give gains and losses across partitions if necessary, as well as the effects of cross flow ventilation on gains and losses to internal spaces and zones.
Using imported profiles from the building program, these casual gains such as lighting, occupancy and equipment are considered as part of the core calculation used in the energy results.
Heat loss calculations can also be performed on a building or zonal basis, the zoning of the rooms being undertaken by simply marking the room profile with the appropriate zone. These can be presented as either a tabular format or each room can be displayed individually taking into consideration internal gains, losses etc.
Individual space details
Part L checks on the efficiency of the building can be carried out to analyse whether the building considered will pass the Part L2B check calculation as well as looking at the CPR rating of offices etc. Any departures from Part L will be listed enabling the engineer to advise the client or rectify as necessary.
The program also incorporates the solar overheating calculation whether in accordance with CIBSE guide H or the Part L calculation. You can decide which methodology to use.
The Cymap program also enables engineers involved in domestic and residential energy efficiency to undertake SAP2009 analysis based on the pre-determined building model.
The program also has an accredited interface with the Governments latest SBEM program which entails transferring building geometric and constructional data information into the freely downloadable industry standard iSBEM interface. This enables production of EPCs to the various standards and jurisdictions involved as set by the various legislative bodies in the UK.
Energy consumption of buildings can also be undertaken to calculate the cooling, heating, lighting and equipment costs based on plant efficiencies, building and plant operating times as well as diversity of occupation.
