The Lighting Project Evaluator provides actionable "how to" guidance on ways to improve your building interior lighting efficiency and reduce your energy consumption, without compromising quality design criteria. Strategies include the use of high performance commercially available products, daylighting, and lighting controls, all within the context of integrated designs supported by performance specifications.
The UAC Cost Estimator provides an alternative to complicated building simulation models, while offering more detail than simplified estimating tools that are commonly available. The estimator accounts for local climate and partial-load, as well as full-load efficiencies. It also helps building owners and operators as they purchase or replace packaged rooftop air conditioning equipment by estimating a product's lifetime energy cost savings at various efficiency levels.
The Building Controls Virtual Test Bed (BCVTB) is a software environment that allows expert users to couple different simulation programs for co-simulation, and to couple simulation programs with actual hardware. For example, the BCVTB allows to simulate a building in EnergyPlus and the HVAC and control system in Modelica, while exchanging data between the software as they simulate. The BCVTB allows expert users of simulation to expand the capabilities of individual programs by linking them to other programs. Due to the different programs that may be involved in distributed simulation, familiarity with configuring programs is essential.
The Rooftop Unit Comparison Calculator (RTUCC) compares high-efficiency rooftop air conditioners to standard equipment in terms of life cycle cost. This web application provides an alternative to complicated building simulation models, while offering more detail than simplified estimating tools that are commonly available. While simplified tools are typically based on full-load efficiencies and full-load equivalent operating hours, the RTUCC accounts for local climate and partial-load, as well as full-load efficiencies.
