Energy modeling is a desk-based process that simulates the energy consumption of a building using available energy data, such as utility bills and smart meter data. It uses what we already know about a building’s systems — including existing lighting, HVAC operations, etc. — and layers in virtual computerized model assumptions about what you could change and how these changes would affect the cost of running your building.
The ultimate goal of energy modeling is to inform energy improvement investments based on sound costs and benefits analysis. As always, Building Energy Performance will start with conservation options first, moving on to energy efficiency and energy management solutions before considering the role of on-site renewable energy.
Load design deals with what your building needs and how its energy systems should be managed to be functional and fit for purpose. There are choices to be made within a load design, but some upfront decisions are necessary when conducting the analysis to produce an energy model. Ideally, the model shows a building’s energy consumption and the cost of that energy use. The choices made within the load design can then be reconsidered and a new energy model produced. Models range in complexity from a simple spreadsheet analysis of an energy measure to a full-blown, custom building model that reflects the construction and operation of your actual facility. Regardless of the complexity, energy modeling can enable building owners to make a sensible decision based on costs and benefits.
We use eQuest, as well as TRACE 700, depending on the requirement. However, some projects require deep expertise, and when it comes to energy modeling, the real nerds of the energy efficiency and renewable energy world are muGrid Analytics. We would certainly turn to muGrid when deep analytical and innovative thinking is required, and you can contact them directly at http://mugrid.com.
