Pulling the Levers on Existing Buildings: A Simple Method for Calibrating Hourly Energy Models

Comprehensive building retrofits require an investment grade audit in conjunction with a calibrated hourly energy model. Even with the most thorough audit processes, uncertainty still remains when identifying and modeling building parameters. This uncertainty propagates throughout the final calibrated model and affects the quality of the energy saving estimates. This paper, geared towards the typical energy analyst, provides a step-by-step process for achieving more reliable results by calibrating an energy model based on actual utility data.

 

Energy Modeling at Each Design Phase: Strategies to Minimize Design Energy Use

Design teams often use energy modeling as an accounting or code compliance tool to establish that minimum requirements are met. Used in this way, significant opportunities to inform and improve building design are overlooked. Properly used, energy modeling can provide outputs that optimize a building’s energy consumption, reduce life cycle costs, and even reduce first cost. This paper will review how and when design teams typically use energy modeling in each design phase (concept phase, schematic design, design development, and construction documentation) and describe strategies for each phase that can lead to lower energy use buildings.
