ENERGY MODELING
Green Technologies provides Building Integrated Energy Modeling addressing Energy Analysis of building energy components and also provides modeling to energy modeling protocols such as LEED, Estidama or ASHRAE.

Green Technologies has been performing energy modeling for over ten years and brings to the project team over 10 years of modeling expertise along with over 30 years MEP design and operations, making this combination a unique asset to the project team.

Green Technologies uses Visual DOE and E-Quest energy modeling software for complex systems, and Carrier’s HAP (Hourly Analysis Program) for basic and simple mechanical HVAC energy and load analysis.

These simulations offer dynamic building modeling that allows System and Plant outputs to directly impact the building’s thermal response.

The software programs calculate the heating and cooling loads, and an integration of all aspects of the simulation (thermal loads, systems, and plants). Thermal calculations and energy consumption analysis incorporates hourly, monthly and annual userdefinable time steps.

Energy Modeling uses Modeling tools which can simulate the interactions of building systems and how they affect overall energy performance. To earn credits for LEED EA Credit 1 - Optimizing Energy Performance, the LEED modeling protocol requires project teams to use such modeling to compare a building’s annual “design energy cost” with the “energy cost budget” for a building of the same use and configuration that complies with ASHRAE 90.1.

ASHRAE Standard 90.1 is the most widely accepted energy standard cited by codes in the U.S. With this as a benchmark, LEED projects are awarded credits on a varying scale, based on the percentage of energy savings predicted to be exceeding the benchmark standard.

Energy simulation tools calculate the major energy uses within a building (such as lighting, space heating, space cooling, fans, pumps, domestic water heating, and plug loads). Generally, the simulations are conducted on an 8,760 hour basis for a one-year period and take into account many significant factors, such as weather conditions and building occupancy schedules that will greatly affect the energy consumption of the building. Energy simulation results identify which aspects of a building will use the most energy, and thus the design elements most in need of improvement. Simulations, when coupled with preliminary costing information, can be the basis for a cost-benefit analysis that identifies the green upgrades that provide cost-effective energy savings and should be included in a building design.

A careful study and analysis of energy simulations can provide information that will allow informed decisions to be made during design, ensuring the project budget is spent wisely and assuming that operating expense of the project when completed is lower than the baseline building.
