In this talk, I will present my research in building energy efficiency and present two current research works: methodology for early design stage optimization and development of a system for personal environment control.
In the different stages of building design, the early design phase offers more opportunities for improving energy performance, as there are a large number of variables and few constraints from other design decisions. Use of energy simulation in this phase can help in achieving energy efficiency through design. Although, there are several simulation tools available, the application of these tools is mostly restricted to the design development stage. Due to a large number of variables in the early design stage, it is difficult for design teams to consider all the possible strategies before taking decisions. In this talk, I will present an early design methodology which recommends design strategies after performing parametric simulations. This methodology is intended to help design teams understand and visualize the spectrum of energy-efficient building design solutions and strategies.
Task-ambient control systems provide personalised comfort to individuals while maintaining acceptable environmental conditions in the ambient space. Occupants can adjust their local environment settings while saving energy and reducing loads. I will present the development of Intelligent System for Personal-Ambient Control and Energy Efficiency (iSPACE) which uses a radiantly cooled workstation table, a smart hub and a smart power strip. This strip uses a regression based intrusive load monitoring technique to identify and control the connected loads. During a demand response event, every individual gets a load budget. The hub controls the task services in response to this budgeted load and targeted comfort levels. The occupant can also trade excess/deficit load with other occupants.
