Energy Modelling for Building Energy Efficiency & Performance Estimates

Driving sustainability goals in the environment today, energy efficiency is a vital measurable factor. Modern building services design consultants require sophisticated and complex types of energy assessments to gauge energy performance in a building accurately and to ensure energy efficiency.?

Energy modelling and performance estimates help building project stakeholders understand the energy consumption of a building before it is built and can help manage a building’s potential energy costs.

What Is Energy Modelling??

Using sophisticated software and complex methods, energy modelling uses sophisticated software and complex methodology to predict actual energy performance. Assessments show how a building retains heat or regulates air quality using various parameters, elaborate calculations – such as a method called SBEM (Simplified Building Energy Model) and simulations. Energy modelling can also show how accurate sustainability design can help fulfil green building requirements.

Energy models are created to:

? Predict energy consumption and costs

? Estimate annual carbon dioxide emissions

? Identify peak demands

? Compare energy efficiency options

? Fulfil building codes and sustainability certification guidelines

?

Benefits of Energy Modelling?

? Providing important data about a building’s use and operating costs

? Assessing energy consumption and energy performance in new buildings and retrofits for zoning compliance and green certification

? Understanding the energy consumption of all building inhabitants and the life cycle costs of energy-related equipment, such as HVAC, lighting, etc.

? Guiding property owners to make informed decisions regarding energy performance

? Calculating energy savings and return of investment of energy conservation measures to improve energy efficiency

Guidelines for Energy Modelling

1. Determine energy requirements — Energy savings depends on the budget, regulatory requirements and utility incentives.
2. Establish base energy usage — Calculate the energy used if building components were manufactured according to the relevant energy code requirements.
3. Collate data — Energy consumption of all building components, mechanical systems and the capacity that equipment will run at and for how many hours must be considered. The local climate, building envelope components, lighting and cooling and heating systems are also considered.
4. Decide energy conservation measures — Determine where energy conservation measures can be used, such as increased daylighting and high-efficiency motors.
5. Implement recommended strategies — Calculate cost savings and ROI to determine effective strategies and implement them.

Performance estimates and energy modelling in building design require the expertise and experience of advanced 3D CAD design services or BIM services from design support partners who are also knowledgeable in heat load calculations, thermal load calculations and CFD simulation services for effective MEP BIM for sustainable construction.
