ARCHITECTURE AND HIGH PERFORMANCE BUILDING AT GEORGIA TECH:TEACHING DESIGN+TECHNOL OGY IN THE ENVIRONMENTAL CONTEXT

Integrative approaches to architectural design+environmental technology pedagogy are essential in educating future generations to respond to impending building energy use challenges.This paper will describe new approaches to incorporating building physics and building technology in the design studio via a diverse cohort of students and faculty,with strong emphasis placed on the development of innovative architectural strategies operating at the intersection of urban demographics,house and housing design,building performance,and sustainability.The United States Department of Energy reports that our buildings account for forty percent of all energy consumed nationally.Our focus on high performance buildings at the Georgia Tech College of Architecture aims to reduce that percentage and meet the rising demand for design and building performance professionals to evaluate the environmental impact of design decisions.Continuing a twenty-five-year trajectory of research leadership,Tech students and faculty are leading the way in digital design,building simulation,engineering,and construction integration.Over the past four years,students from various schools across campus have been working together in a seminar and design studio setting to expand 21st century housing options.Changing urban demographics,sustainability targets,and alternative energy requirements are investigated through smartly researched and elegantly designed housing and public space propositions.The move from an ecologically aware architecture towards an architecture immersed in the emerging debates about carbon footprint and energy consumption is in part driven by increasing international concern over resource availability and delivery.Through reduced costs of alternative energy capture,higher efficiencies,rapid evolution of upstream technologies and applications and more robust software platforms along with growing social,political and economic debate,the definition of sustainability is evolving - moving to transform integral parts of archi-tectural practice and education from a primarily aesthetic and assembly oriented tra-jectory to a more comprehensive understanding of the relationship between design thinking and building performance.

OPTIMAL ENERGY DESIGN AND RETROFIT RECOMMENDATIONS FOR THE TURKISH BUILDING SECTOR

This paper introduces methodologies and optimal strategies to reduce the energy consumption of the building sector with the aim to reduce global energy usage of a given region or country.Many efforts are underway to develop investment strategies for large-scale energy retrofits and stricter energy design standards for existing and future buildings.This paper presents a study that informs these strategies in a novel way.It introduces support for the cost-optimized retrofits of existing,and design improvements of new buildings in Turkey with the aim to offer recommendations to individual building owners as well as guidance to the market.Three building types,apartment,single-family house and office are analyzed with a novel optimiza-tion approach.The energy performance of each type is simulated in five different climate regions of Turkey and four different vintages.For each vintage,the building is modelled corresponding to local Turkish regulations that applied at the time of construction.Optimum results are produced for different goals in terms of energy saving targets.The optimization results reveal that a 50%energy saving target is attainable for the retrofit and a 40%energy saving target is attainable for new design improvements for each building type in all climate regions.
