title: Thermal Design and Optimization
author:  Adrian Bejan 
description: An extremely lucid presentation of the thermal energy topics of heat transfer, fluid mechanics and thermodynamics as applied to design systems practices including economics, system simulation and optimization techniques. Draws from the best of contemporary thinking regarding design and its methodology. Includes a case study, used throughout the book, which involves the design of a cogeneration system.

  Abstract: This study presents a multi-objective optimisation of building thermo-modernisation
  for multi-family buildings. The applied model has considered alternative solutions for insulation
  materials, with diﬀerent thicknesses and diﬀerent types of windows. The weighted sum method was
  applied to ﬁnd a
