A Climate-Responsive Adaptive Control for a Combination Passive Solar Shading and Natural Ventilation

EPA Grant Number: SU835520
Title: A Climate-Responsive Adaptive Control for a Combination Passive Solar Shading and Natural Ventilation
Investigators: Baur, Stuart W.
Institution: University of Missouri - Rolla
EPA Project Officer: Levinson, Barbara
Project Period: August 15, 2013 through August 14, 2014
Project Amount: $15,000
RFA: P3 Awards: A National Student Design Competition for Sustainability Focusing on People, Prosperity and the Planet (2013)
Research Category: P3 Challenge Area - Built Environment , P3 Challenge Area - Energy , Pollution Prevention/Sustainable Development

Description:

Currently, nations around the globe are facing striking concerns regarding energy consumption. In the United States, we face increasing demands that will cause increasing fuel prices thus ultimately higher-energy cost. The future could be eased by reduce energy consumption through energy-efficient technologies. This trend challenges us with finding both cost effective and energy-efficient strategies.

Objective:

The proposed research is to develop a predictive environmental control based on the use of a passive shading system in combination with natural ventilation based on real-time sensing of outdoor climate conditions, as well as indoor thermal environment.

Approach:

In a pilot study, the project investigators carefully evaluated the availability of natural light with the weather data of Rolla, Missouri, and estimated that 20% of the energy required for cooling and heating a home could be realized by adopting fixed solar shading system and natural ventilation as a passive strategy. The proposed strategy will be able to predict the optimal strategies for indoor climate of a specific house on the basis of sensing outdoor weather conditions, and to drive the actuators of operable windows to maintain a thermal condition that creates a comfortable environment, while minimizing use of the mechanical systems installed in the selected house.

Expected Results:

The project outcome includes (1) these strategies can significantly contribute to environmental sustainability by energy savings, and (2) which parametric options for adaptive controls can be used to maximize the savings potential. The proposed strategy will be able to predict the optimal strategies for indoor climate of a specific house on the basis of sensing outdoor weather conditions, and to maintain a thermal condition that creates a comfortable environment, while minimizing use of the mechanical systems installed in the selected house. In return the average home will be able to attain upto 20% of the energy savings required for cooling and heating a home could be realized by adopting fixed solar shading system and natural ventilation as a passive strategy.

Supplemental Keywords:
