Mago, Rogelio Luck, Heejin Cho. Thermal mass is ideally placed within a building where it is shielded from direct solar gain but exposed to the building occupants.
It is therefore most commonly associated with solid concrete floor slabs in naturally ventilated or low-energy mechanically ventilated buildings where the concrete soffit is left exposed to the occupied space. Mapping Thermal Mass Benefit September 2 1 INTRODUCTION Residential and commercial buildings consume 41% of the total energy used by all sectors of the economy .
As climate change becomes an increasingly important concern, identifying strategies to ensure energy efficiency in buildings has become a key focus of the building industry.

The studies have demonstrated significant savings potential for use of building thermal mass in commercial buildings. However, the savings are sensitive to many factors, including utility rates, type of equipment, occupancy schedule, building construction, climate conditions, and control hamptonsbeachouse.com by: Night ventilation is a low energy strategy for cooling a building.
It works by using natural or mechanical ventilation to cool the thermal mass of exposed internal building surfaces at night so that they can absorb heat during the day, thus requiring less energy for conditioning the air.
The aim of this paper is focused on the energy performance of buildings containing massive wall alternatives. The analysis comprised the comparison of the heating and cooling loads of seven characteristic wall configurations of one sample building with different dynamic internal heat capacity (ISO ) in spite of the equal thermal hamptonsbeachouse.com by: 3.

For overall project economy, however, the industry suggests a parametric analysis to determine reasonable insulation levels for the building envelope elements.
The effectiveness of thermal mass varies with factors such as climate, building design and insulation position. The effects of insulation position are discussed in the following sections. This paper introduces the concept of Thermal Autonomy as both a metric and a design pro- parametric building thermal simulation and analysis.
During these periods shaded thermal mass that is purged of heat at night can provide comfort. Using the developed integrated radiant floor and ceiling model, a series of parametric analyses is carried out to examine the transient thermal performance of radiant floor heating and radiant ceiling cooling system for various insulation configurations, building thermal mass, building zoning configurations, and climatic hamptonsbeachouse.com by: 1.
including the level of thermal mass and insulation, as well as the control of solar gains and the space heating strategy. A frequently-cited technique for design is parametric or sensitivity analysis (Hayter et al. A major limitation to this method is that parameter interactions are overlooked.
For instance, the parametric analysis might be. Sefaira’s industry-leading Real Time Analysis and powerful parametric analysis capa-bilities make it easy to do the types of comparisons and optimizations described above.

In addition to the above-mentioned building sizes and thermal mass levels, we consider climate zones and different DR control strategies. There are a total of simulation runs, 81 runs for the concrete building and 81 runs for the steel frame building.
Thermal Mass in Summer. Thermal mass can significantly reduce cooling loads on a building, in both dwellings and larger buildings. During summer months, any heat gain during the day is absorbed by the thermal mass in the walls, floors and ceilings, preventing an excessive temperature rise.May 09, · 1.
Understand your building’s energy profile. In order to do this effectively, we must first understand what’s going on in our Part L baseline building. Running analysis on the shaded building in Sefaira’s web app confirms that it is cooling dominated design, as suggested by our earlier results in the Sefaira for Sketchup Plug In.Thermal mass in a building can store the sun's energy as well as reduce the temperature swings throughout the day.
The ability for materials to hold heat is determined by their specific heat—the amount of heat per unit of mass required to raise temperature by one degree.
