Pattern r+d offers integrated energy modeling.​We use a unique parametric process allowing designers to alter their designs with multiple iterations to test for performance associated with each iteration.​Unlike traditional mechanical engineers that come in towards later stages of a design process, Pattern r+d uses a rapid feedback methodology to give designers feedback regarding energy, daylight, glare, comfort and more when it would make the most difference. The upcoming energy codes require a much more integrated approach to architecture and building performance. Previously, code changes have been absorbed by the mechanical engineers. However, soon even code minimum will be difficult without energy modeling.

Typical Services

Early Stage Energy Modeling \ Design Phase – Pre design, Concept Design, Schematic Design


This is an example project that shows the flexibility the designer has towards testing various building massing models and have the changes in massing clearly reflect in the energy use of the building. Interestingly, the North-South facing  building orientation is not the best case, sometimes the most intuitive answers are not correct, which is why we need simulation.

Detailed Energy Modeling \ Design Phase – Schematic Design, Design development, Construction documentation
Capture10 story south tower + 5 story west building with a Glass Area of 24,344 sf total of vertical glazing on West and South elevations in Charleston South Carolina. A detailed simulation was conducted to test configurations of shading devices. The overall analysis used eQUEST, Energy Plus, TRANE, COMFEN, and Radiance.

LEED Compliance EAp2, EAc1\ Design Phase – Design development, Construction documentation
LEEDThis office bulding project required preparation of a full LEED compliance model for USGBC submission for EAp2 and EAc1, based on approved shop drawings and all required documentation. The task involved coordinating all design info and checklists. Preparation of two digital energy models: ASHRAE 90.1 Baseline and Proposed Design,  Prepare all required documentation and go through review process.

Custom Analysis (Example: Finding the optimal glass product for reduced energy, cost but highest interior daylight) \ Design Phase – Schematic Design,  Design development, Construction documentation

Picture2The design team presented 5 possible glass type options for each facade orientation. This generated a total of 25 total options to know that option 2 and 6 lead to a 22.3% energy savings as compared to ASHRAE 90.1 baseline. The decision involved 3 key factors – Energy Use, Cost of Glass and Interior daylight
