The course is aimed at acquiring a thorough knowledge of the technologies for energy savings, considering their environmental impact where possible the exploitation of renewable energy sources. The most common technologies will be analysed, with reference to their functional characteristics, their integration into the urban context, the criteria for choosing between the technical and economic alternatives, their location aspects and economic incentives. Constitute topics of the course: - Action Plans for Energy and Environmental Protocols that combine the achievement of energy savings with minimal impact on the environment, land and human health - Technologies for the production of energy from renewable sources and their availability on a regional scale - Assessment of energy requirements for buildings on an urban scale - Energy saving technologies in the residential sector - Tools for the control of energy saving and of noise and light pollution.

Ability to: - Analyze the characteristics of the built territory by assessing the main impacts in terms of climate, energy resources and finally air, noise and light pollution - Assess the needs and criteria of territorial distribution of energy consumptions and energy sources. EN: could be interesting to follow the courses: Technology for renewable energy sources, Energy savings and comfort in buildings and Models and scenarios for energy planning (Ingegneria Energetica e Nucleare).

Knowledge of the fundamentals of: energy efficiency of residential systems, renewable technologies, thermodynamics, light, acoustics; and know how to use GIS software.

The course is structured around the following themes: - Assessment of energy needs for space heating and domestic hot water production of the residential building stock in Turin; considerations on the age and on the compactness of the buildings (through the surface to volume ratio S/V). - Feasibility of using solar energy at the regional, municipal and district scale; - Feasibility of the technologies that use forest biomass at local scale and considerations on supply energy; - Improvement the energy efficiency solutions and the effectiveness of the different retrofit interventions - Evaluation on energy policies that could be implemented on the territory.

The hours of teaching can be divided into hours of theoretical lectures and practical lessons. Practical lessons consist in the development of the analysis of the site relative to one or more areas on the territory, in particular analyzing energy consumptions and the available renewable energy sources. It is required the development of numerical exercises using GIS software.
