Optimization of thermal comfort in building through envelope design  [PDF]
Milorad Bojic,Alexandre Patou Parvedy,Harry Boyer
Computer Science , 2013,
Abstract: Due to the current environmental situation, energy saving has become the leading drive in modern research. Although the residential houses in tropical climate do not use air conditioning to maintain thermal comfort in order to avoid use of electricity. As the thermal comfort is maintained by adequate envelope composition and natural ventilation, this paper shows that it is possible to determine the thickness of envelope layers for which the best thermal comfort is obtained. The building is modeled in EnergyPlus software and HookeJeves optimization methodology. The investigated house is a typical residential house one-storey high with five thermal zones located at Reunion Island, France. Three optimizations are performed such as the optimization of the thickness of the concrete block layer, of the wood layer, and that of the thermal insulation layer. The results show optimal thickness of thermal envelope layers that yield the maximum TC according to Fanger predicted mean vote.

Abstract: Improving the thermal performance of building envelope is an important way to save building energy consumption. The phase change energy storage building envelope is helpful to effective use of renewable energy, reducing building operational energy consumption, increasing building thermal comfort, and reducing environment pollution and greenhouse gas emission. This paper presents the concept of ideal energy-saving building envelope, which is used to guide the building envelope material selection and thermal performance design. This paper reviews some available researches on phase change building material and phase change energy storage building envelope. At last, this paper presents some current problems needed further research.

Thermal Load Reduction with Green Building Envelope  [PDF]
Dilawar Husain, Sarvesh Shukla, Vivek Kumar Umrao, Ravi Prakash
Open Journal of Energy Efficiency (OJEE) , 2017, DOI: 10.4236/ojee.2017.63009
Abstract: Various studies have confirmed that high thermal resistance in roof & wall can reduce the heat transfer load of the buildings. In this study, experimental investigation of the effects of some sustainable features (such as green roof, reflective coated roof & Fly ash brick (FAB) etc.) on the building has been conducted in the Indian context. For the purpose, two scaled building models i.e. Model I (conventional design) & Model II (green design) have been examined with different design configurations. The sensible heat transfer (SHT) load of the building is reduced by 21% - 29% through the use of FAB with cavity wall in place of Fired clay brick (FCB) wall. The load reduction increases to 26% - 44% by using FAB cavity wall with reflective coating on the roof. This reduction further increases to 64% - 68% with FAB cavity wall along with green roof. In this final scenario, the monthly electrical energy saving for air-conditioning is approximately 5.1 kWhe/m2 per unit envelope area, with associated reduction in GHG emissions up to 6.36 kg CO2eq/m2 per unit envelope area, assuming continuous operation of HVAC systems.

Magazine of Civil Engineering , 2012,
Abstract: The research presents the calculations for the heat losses through the envelope of the apartment building. The calculations are provided for different levels of insulation of enclosing structures (i.e. wall, windows, roof etc) according to three normative documents: Set of rules 50.13330.2012 (rus), Construction Norms and Regulations 23-02-2003 (rus) and National Building Code of Finland, Part D3 (fin). The impact of level of thermal protection of external enclosure structures on the values of heat losses, the operating costs and the costs of fuel and energy resources during the heating period (for 10, 30 and 50 years of upkeep of buildings) on the example of the one habitable apartment building is analyzed. Calculation of payback periods of the energy saving actions directed on increase of level of thermal protection of external enclosure structures of buildings is given. Economic efficiency of investments in energy saving measures is analyzed.

Abstract: We analyzed the relationships between the human body exergy balance and behavioral adaptations induced by undesirable cold storage by a building envelope under an unsteady-state thermal environment in winter. The complex interaction of the warm exergy production by shivering, lifting of the shell ratio, and reduction of the blood flow rate was considered to constitute the physiological adaptation necessary for maintaining the constant core temperature, which was an important aspect in living organisms. In the case of intermittent use room, it was suggested that better thermal comfort and desirable behavioral adaptations, which decreased the consumption of fossil fuels, could be achieved if interior wooden cladding was used in constructions with building envelopes that had a comparatively large heat capacity, or in cases of wooden constructions in which the building envelope heat capacity was comparatively small.

Abstract: A thermocamera can be used for the assessment of building envelopes. Thermal bridges and their seriousness can be detected by a thermocamera. We used these measurements for the detection of thermal bridges and then for the assessment of improving steps on the building envelope. We used these measurements to compare envelopes of two objects of the same panel system which have been revitalized in different ways.

Abstract: Building envelope is a fence that controls heat exchange between interior and exterior and plays an essential role in providing thermal comfort conditions of residents. In recent years, due to the necessity of conserving energy and also preventing increased environmental pollution, the importance of sustainable construction has been doubled. Checking the problems of thermal behavior of the building envelope materials, and what influences in the heating and cooling loads exerted and energy consumption of buildings, are the questions that this research seeks to answer. In this regard, building information modelling analysis (BIM) has worthy contribution in the completion process of sustainable design; thus using software Design Builder, it is paid attention to simulation of the thermal behavior of two types of defined materials for the building envelope that was designed as a Research Institute of Renewable Energy of Yazd University. For Type 1 materials, two layers of brick have been selected, and for Type 2 a thermal insulation layer also added it. Results of the analysis showed that the use of materials Type 2 in the cooling load %4.8 and in the thermal load %62.5 reduction can be achieved which means reducing the load on active system and thus reducing the initial cost of building. Also reduction in annual energy consumption by almost %2.4 for cooling and %62.9 for heating buildings have been achieved, which makes saving non-renewable energy consumption, and consequently reducing environmental pollution as well as reducing current costs will be established.

Abstract: Buildings are responsible for about 30 % of the total energy consumption of Latvia. Specific heat consumption is 200-225 kWh/m2 per annum, for its part the average consumption of one household is about 1000-1200 kWh per annum. Due to increasing needs for comfort, an increase in the total area of buildings covered by glass, as well as intensified interest in establishing a good microclimate in buildings, there is also increasingly more attention paid on to the cooling load of buildings and the related heat transfer and exchange processes. Thermal inertia and the thermal mass of building envelope are main factors, which substantially influence the amplitude of changes in temperature and the period during which the internal temperature is dependant on the external temperature.
