TDE provided sustainable engineering design services for two private residences located near Spoleto, Italy. The first is a 3,500 square foot renovation of a historical stone building located in the town of Bazzano overlooking an olive grove. State of the art technologies integrated into the house will make it an example of energy efficient design and reduce energy costs, which are exceedingly high in Italy. MEP and sustainable systems will focus on utilizing the inherent thermal mass, natural daylight, and natural ventilation on site. These will be assisted by passive systems such as radiant floors and solar hot water. Also renewable energy generation with photovoltaics will take advantage of the large south facing roof area and sunshine to provide site electricity.

The second residence is a 4,300 square foot renovation of an existing stone watchtower in the town of Lenano. A geothermal heat pump will provide all heating and cooling needs, while the residence will be ventilated and conditioned by a combination of both passive and active systems. Natural ventilation will complement radiant floors as the primary ventilation and air conditioning systems. Doors and windows on opposing walls will help create a natural cross breeze. Elevated perimeter windows would also help exhaust rising warmer air while cooler air enters through the main level windows and doors. Due to the relatively high winds on site, wind turbines will assist in electricity generation.
