TImmons Design was commissioned by Green Energy Group to provide Mechanical, Electrical, Plumbing and Sustainable design for the Khalifa Oasis Sustainable Community project. The Community, located in Abu Dhabi, United Arab Emirates, includes the development of 73 three-bedroom townhouses spanning approximately 283 square meters on two-levels, surrounding a community shared central pavilion, swimming pool and Jacuzzis.

The development aims to achieve a goal of LEED Silver for the whole community and LEED Gold for the Community Center building that is located in the center of the development. The design was adapted for the desert climate and made use of the abundant natural resources of the area. Daylighting was modeled and maximized, as well as balanced with the cultural architectural aesthetic. Solar exposure was also modeled to minimize excessive heat gain to the villas. Thermal mass was analyzed in order to shift the cooling load to later in the day, thus reducing energy consumption through harnessing of thermal lag.

Renewable energy generating systems were maximized throughout the development. Wind turbines were sited at the entrance to the project site to generate electricity for nighttime lighting of the landscape and also became an architectural kinetic feature to express project greenness and sustainability of the development. Building Integrated Photovotaics (BIPV) were integrated into the design of all of the villas to provide power for each unit.

Geothermal was used to provide heating and cooling to the community center, maximize energy savings and reduce maintenance costs. The swimming pool, located next to the community center, was used as a heat sink for the geothermal system. The piping loops were located within the walls of the pool, allowing heat to be pulled from the pool in the winter and rejected to the pool in the summer months.
