After the energy consumption of the project has been reduced using the results from a whole building energy simulation model, the remaining energy consumption can be further reduced by installing onsite renewable energy systems such as Photovoltaics and Solar Hot Water. Increasing the building’s efficiency reduces the energy needed from renewable systems to meet the targeted portion of the load, or allows the same size system to meet a larger portion of the load.
LEED awards points for Onsite Renewable Energy (EAc2). It’s important to use the results from the energy simulation to determine how much renewable energy is required in order to maximize LEED points without exceeding the construction budget.
There are several factors that influence the amount of annual electricity produced by a PV system and payback time of the PV system. The location of the project, panel orientation, mounting and tilt, and shading are all important factors to consider before a PV system is designed.
The Brummitt team provides a project-specific, detailed analysis that will determine the optimum configuration and size that should be used to meet your energy-efficiency targets and increase incentives. The team’s custom detailed analysis will identify the most cost-effective solution for each project.
Solar Hot Water
Hot water heated by the sun is used in many ways. While perhaps best known in a residential setting to provide domestic hot water, solar hot water also has industrial applications like to generate electricity. Designs suitable for hot climates can be much simpler and cheaper and can be considered an appropriate technology for these places.
For buildings with a large domestic hot water load– residential, hospitality, hospital–solar hot water systems tend to be relatively economical and have a shorter payback than PV systems.
