Energy -efficient building design involves minimizing the energy use and optimizing the
performance of individual systems and components of the building . The benefits of energyefficient
design , in the residential sector , are direct and tangible , provided that design strategies
with a substantial combined energy and cost -saving potential are adopted .
Many studies have been performed to evaluate the energy -saving potential and the costeffectiveness
of various design options , and to identify conditions for optimizing the performance
of building systems and components . The results of these studies , published in various resources ,
were analyzed discretely using different techniques , and were reported using different bases for
comparison . Considering the complex interaction of , and energy flows through various building
components , it is difficult to directly compare /combine the results from various studies to
determine the energy -saving potential of combination of strategies , and to select an appropriate
set of strategies for making design decisions .
Therefore , this thesis develops a comprehensive survey and analysis of energy -efficient
design strategies and their energy -saving potential , in isolation as well as in combination , using a
DOE -2 simulation model of a prototype house in the hot and humid climate of Houston , Texas .
Optimized strategies that included building configuration , materials / assembly for building
envelop components , and efficient mechanical and electrical systems , equipment and appliances ,
were applied in combination that could minimize the annual energy use . Application of these strategies is expected to allow downsizing systems and equipment and to confirm their operation
at their rated performance , resulting in additional installation and operation cost savings .
The study is concluded by outlining the procedures for selecting optimized set of
strategies , and by developing guidelines for achieving maximum energy -efficiency in singlefamily
detached houses in hot and humid climates . Thus , this study will facilitate the selection of
energy -saving measures for their individual or combined application for developing energyefficient
residences in hot and humid climates . |
