1. 1. Energy analysis between traditional hot water circulation system and an innovative pipe-in-pipe system

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Alejandro Abellán Guallarte; [2022]
   Keywords : Hot water circulation; pipe-in-pipe; energy saving; buildings; heat losses; warm water;

   Abstract : We are at a time when energy efficiency and the reduction in the use of non-renewable energy is an important objective in all aspects and will continue to be so, therefore it is necessary to try to reduce energy and heat losses in the systems used in homes and, in particular, in the domestic hot water (DHW) system. This study aims to find out the advantages and disadvantages of an innovative pipe-in-pipe (PIP) system for DHW circulation with respect to the conventional system of two separate pipes. READ MORE

3. 2. Thermal Shape Factor : The impact of the building shape and thermal properties on the heating energy demand in Swedish climates

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Martin Olsson; [2016]
   Keywords : Heat loss coefficient; Building shape; Thermal properties; Calibration;

   Abstract : In the year 2006, the energy performance directive 2002/91/EG was passed by the European Union, according to this directive the Swedish building code was supplemented by a key measure of energy use intensity (EUI). The implemented EUI equals some energy use within a building divided by its floor area and must be calculated in new housing estate and shown when renting or selling housing property. READ MORE
