SBEM, or SBEM calculations are normally used to try and demonstrate the energy performance of extended non-dwellings. In other words, it is anything other than your residential scheme.
We are highly experienced when it comes to SBEM calculation and we are very experienced when it comes to dynamic modelling as well so you know you can always count on us to get the job done. When you hire us for the job, we will do everything we can to meet the Part L2 requirements and our calculations are always performed in-house by our energy assessors.
They are fully available to give you as much advice as you want, when you need it.
SBEM explained is the Simplified Building Energy Model. It is government approved and it can be used to calculate the energy that is needed to heat, light and ventilate the building over a year long period.
If you are still wondering “what is SBEM for a commercial property” then in a commercial building, the compliance can be carried out with a dynamic model. This is otherwise known as DSM and it can give you a much more detailed and much more accurate assessment. This can let the assessor create a 3D model of the building and it can also help to simulate the effects of daylight and even sunlight as well. Various factors can come into this and it can include walls, floors, roofs and even the windows. The ventilation system, heating system and even the hot water system are also managed and monitored as well.
It is important to understand that in most cases, there are two stages to the initial assessment and this is the design required and the as built. These are both required if you want to get an EPC.
We always make sure that we use state of the art software and tools when it comes to checking the lighting, comfort, carbon and other types of performance. Our building simulation allows us to compare the function and even the performance while effectively delivering results over time.
The end result is either a pass or a fail and our assessors have all the experience you need to ensure a pass without compromising or changing your design. If you wanted, we could even take care of your extensions, your conversions and any change of use projects that you have as well. A SBEM calculation would be required here as well, and that is just one of the many things that we can help you with.
DSM is a very accurate and very powerful tool that is used to measure how a building performs. It can be used to measure any number of factors and this includes the energy compliance it has to offer and the amount of Co2 emissions as well. This can lead to help managing overheating and any lighting issues that might be present.
DSM is far more commonly used for anything that is non-domestic. This can include very large developments such as hotels and even office blocks. A lot of clients that come to our company are M & E engineers and consultants. They have the ability to carry out a detailed analysis and they can also assist you with the early stages of your design as well. All in all, DSM allows you to get a much more efficient analysis when it is paired with Part L assessment tools such as SAP and SBEM. This is mostly due to the emphasis that has been put on external factors such as solar gain and even the effect of glazing.
The DSM process all starts with geometry. The assessor will start by creating a 3D model of the building. Software tools are then used to try and create an analysis of:
- Thermal Performance/Construction
- Renewables and Technologies
- Energy usage
- CO2 Emissions
- Daylight/Sunlight Assessment
- Occupant Comfort
- BREEAM / LEED Performance
