Energy Efficient Tactical Shelters
Agency / Branch:
DOD / USAF
ABSTRACT: During Phase I, SES modeled the fuel consumption of a baseline shelter and then modeled the interactive effects of using fuel efficient technologies (lighting, climate control, etc.) instead of the baseline technologies. This work demonstrated the feasibility of improving the fuel efficiency of shelters by more than 50%, by combining several innovative commercial off the shelf (COTS) technologies. To validate this result, comparative testing of shelters is required, with and without relevant technologies, in a laboratory environment. The Phase I model shows that climate control accounts for up to 75% of fuel used in the baseline shelter. Building envelope (insulation, etc.) technologies can reduce this use of energy. In Phase II, SES will develop and demonstrate a shelter laboratory, and will use it to develop, optimize and demonstrate a prototype deployable shelter envelope kit. The kit will include multiple building envelope systems, packaged to make the installation and use of this optimized combination of envelope technologies easy for shelter users. The lab will be used to show that the kit can save 15 30% of shelter fuel, and to demonstrate, on a proof of concept basis, that additional technologies can be added to achieve the original 50% fuel reduction target. BENEFIT: If successful, this Phase II R & D will result in the availability, for the first time, of a demonstrated, optimized, shelter envelope system that combines existing technologies in an innovative way so as to enable shelter users to reduce their fuel use by 15 30%, without loss of any relevant functionality, including no loss of interior space. Military users will have an immediate interest in using this system, to reduce fuel costs and the risks associated with the delivery of fuel in deployed situations. Commercial markets are also expected to exist. The size of mobile buildings, whether purpose-built or made from retrofitted shipping containers, is fixed by the standardized size of roads and transportation equipment. Therefore, similar mobile buildings used by other government and private sector entities also have restricted interior space, and, therefore, the envisioned kit would be suitable for use with most mobile buildings. Some users of mobile buildings, such as mineral exploration companies, scientific research organizations, remote telecommunications infrastructure maintenance, and so forth, deploy the buildings to very remote locations. By their nature, such locations do not have established energy delivery infrastructure. Therefore, although not often as high as military fuel costs, the cost of fuel delivered to such remote locations is also very high. All of these organizations, therefore, have a stronger interest in fuel efficiency than average mobile building users. They would, therefore, also have an interest in retrofitting the mobile buildings they have purchased or leased for use in remote locations by using envisioned optimized mobile building envelope kit. As the kits are put into large-scale production and costs come down, further markets can be expected to exist in less and less remote locations; it is possible that the kit may also find buyers in markets with established infrastructure that have high energy costs, such as towns in Alaska.
