The overall objective of the proposed research is to develop mathematical models to conduct high resolution simulation of novel environmental-friendly advanced building integrated energy systems and their optimal configurations and control strategies that can be used with state-of-the-art building energy simulation software for the design, analysis, and development of super energy efficient buildings towards the net-zero energy building status. The research is divided into five subprojects: 1) Identification and Optimization of Housing Characteristics of Super Energy Efficient Solar House, 2) Development of Least Cost Energy Retrofit Upgrades Towards Net-zero Energy Status, 3) Modeling of Integrated Wind, Solar PV and Thermal, and Heat Pump Hybrid Energy Systems, 4) Development of Optimal Predictive Control of Combined In-floor and Radiant Conditioning System with Hybrid HVAC Systems in Solar Houses, 5) Dynamic Whole House Modeling and Simulation of Net-Zero Energy House. The research will focus on new and innovative renewable energy technologies such as solar hybrid PV/thermal collectors, solar assisted air- and ground-source heat pumps, combined infloor/radiant panel/forced air spacing conditioning system, strategic applications of thermal mass and phase change materials as integral part(s) of the building, and hybrid combinations of different systems, as well as their overall optimal control strategies considering the building and its HVAC system dynamics and short term weather forecast information for maximum utilization of on-site renewable energy potentials while maintaining optimal thermal comfort. Proper configuration, integration, and control of the advanced hybrid building integrated energy systems are the major key drivers in advancing next level of energy efficiency in building towards net-zero energy status. The results from the proposed research will provide realistic and accurate modeling tools for designing, assessing, and component sizing of building integrated renewable energy systems and their optimal control strategies in advanced hybrid HVAC systems to foster faster adoption of these environmental-friendly, clean energy systems in the building sector.
