Energy Modeling

Energy Modeling, or Building Energy Simulations, is a tool to solve key green building design issues in order to maximize energy conservation and reduce carbon emissions by parametrically optimizing building energy performance.  Energy modeling in the early design phase of a project will help to determine the best way to lower energy costs while maximizing LEED credits (LEED™ EA Credit 1 Optimize Energy Performance, 1-19 Points) for certification. We are experts in energy modeling and have team members that have performed analyses on over 50 million square feet of facilities, including many flagship projects.

 

Renewable Energy Analysis

Once the building is optimally designed and its energy consumption reduced using the results from the building energy simulation model, energy consumption can be further reduced by installing onsite renewable energy systems such as photovoltaics, solar hot water, etc. Green Living can perform an energy analysis for onsite renewable energy systems and evaluate potential LEED points for On-site Renewable Energy (EAc2). Incorporating on-site renewable energy into a project also helps to increase the points for EA Credit 1: Optimize Energy Performance. It is important to use energy simulation results to determine how much renewable energy is required in order to maximize LEED points without exceeding the construction budget.

 

Energy Audits

Energy audits are holistic analysis of an existing facility, performed to understand how energy is currently used and to identify areas of potential savings. Energy audits are used to evaluate energy performance under LEED for Existing Buildings: Operation & Maintenance (LEED™ EBOM) prerequisite (EAp2: Minimum Energy Efficiency Performance).

An energy audit consists of three main components:

  • Analysis and understanding of energy uses
  • Identifying potential energy savings, carbon footprint, and operating costs
  • Reporting cost-benefit recommendations and evaluating return on investment

Typically an energy audit is conducted to seek opportunities to reduce the amount of energy input into the system without negatively affecting the output(s). When the object of study is an occupied building then reducing energy consumption while maintaining or improving human comfort, health, and safety are of primary concern. Beyond simply identifying the sources of energy use, an energy audit seeks to prioritize the energy uses from the greatest to least cost-effective opportunities for energy savings.

Green Living will assess the comprehensive energy usage of your facility to analyze the potential for improvement in various areas. We can customize the audit to your particular needs. It may be a simple walk-through to identify major problems and make basic recommendations, or we can perform a more detailed audit. An in-depth, exhaustive audit may include monitoring specific equipment over time, interviewing facility personnel, and reviewing the annual energy billing profile. We can frame energy-related measures within a business context, factoring in initial investments and rates of payback, utility demand-rate structures, and possible productivity gains to make both financial and environmental sense.

 

Daylighting Analysis

LEED™ NC and LEED™ CS Credit IEQ 8.1 Daylighting & Views (1 point)

“LEED NC and LEED CS Credit IEQ 8.1 may be met by simulating the dynamics of daylighting, or by conducting actual daylight measurements after construction.”

Good daylighting cannot easily be retrofitted into an existing building. Unless daylighting is given attention from the early design stages, the building will not develop its full potential for optimal daylighting performance. Green Living can perform a computer simulation in the design phase to determine if the required brightness of 25 foot-candles is achieved in 75% of all occupied spaces. The model will also be used to determine light pollution if attempting SSc8: Light Pollution Reduction.
