Pre-design modeling and analysis of energy-related and water-related systems are required to inform an optimized design.
Energy-related analysis involves preliminary modeling of at least two out of seven options; one of which is to assess insulation values and other attributes of the basic envelope. The project then reports how the analyses impacted design including elimination or downsizing of building systems, such as HVAC, exterior materials and finishes.
The thermal mass and heat capacity of concrete masonry has been shown to benefit energy design, and in most cases significantly contribute to reduction in HVAC requirements. The 2016 California Energy Code (CEC) recognizes and accounts for concrete masonry as a heavy mass wall.
In most Southern California climate zones, insulation is NOT required for concrete masonry walls 8-inches and greater in width. See Optimize Energy Performance
Concrete masonry is also multi-functioning, where the structural wall also serves as a contributor to energy design and as a finish material, potentially eliminating multiple materials. See Efficiently Green: Multi-Function Products & Systems.
Water-related analysis includes strategies in the site design for rainwater quantity and quality management systems. Permeable interlocking concrete pavements (PICP) create systems that capture, control, and clean potential site runoff.
