Analysis and Optimization of CO2-networks

Student Projects

Abstract

This project has been motivated by the desire to provide a sustainable thermal energy network combining low environmental impact, high energy efficiency and high profitability. It suggests alternative optimal scenarios to satisfy the heating and cooling demand for buildings located in a district of Switzerland in full expansion and modernization. In the perspective of the future Solar Decathlon integration in this zone, its possible im- plementation within the best network scenario has been investigated to identify the future possible combination of this two sustainable systems represented by the CO2 network and the Solar decathlon pavilion.

Zero-energy building

A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows and insulation, and solar panels. The goal is that these buildings contribute less overall greenhouse gas to the atmosphere during operations than similar non-ZNE buildings.

Efficient energy use

Efficient energy use, sometimes simply called energy efficiency, is the process of reducing the amount of energy required to provide products and services. For example, insulating a building allows it to use less heating and cooling energy to achieve and maintain a thermal comfort. Installing light-emitting diode bulbs, fluorescent lighting, or natural skylight windows reduces the amount of energy required to attain the same level of illumination compared to using traditional incandescent light bulbs.

Cooling tower

A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream, to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of dry cooling towers, rely solely on air to cool the working fluid to near the dry-bulb air temperature using radiators.
