Thermal testing of the proposed HUD energy efficiency standard for new manufactured homes

In order to solve problems of high energy consumption and poor indoor thermal comfort in existing rural residential buildings, Tianjin city developed Tianjin energy efficiency standard for rural residential buildings, the building envelope insulation technique in the standard-including determination of heat transfer coefficient, principle of choosing insulation materials for building envelope, energy efficiency standards of walls, windows, and roofs are unscrambled particularly in this paper. It is suggested that natural materials and appropriate techniques are used to achieve the energy-saving goal for rural residential buildings with minimum energy consumption.

Energy Efficiency Standards

The energy efficiency of residential buildings is a central issue in the widely discussed energy transition. This study investigates which factors influence homeowners´ decisions regarding the energy efficiency standard of their houses. Homeowners who built or renovated their houses between 2008 and 2013 participated in a questionnaire survey in two Austrian “energy regions” within the federal states of Styria and Burgenland. In the majority (66%) of cases, homeowners chose the low-energy house standard B (≤ 50kWh/m2a) for their building or renovation projects, followed by the conventional standard C (≤ 100kWh/m2a) (21%). Only 13% realized ultra-low-energy, passive or plus-energy houses with a higher energy efficiency standard (A (≤ 25kWh/m2a), A+ (≤ 15kWh/m2a), or A++ (≤ 10kWh/m2a)). Expert recommendations on energy standards showed the highest correlation with the selected standards, and on average, new building projects realized better energy efficiency standards than did renovations. Further variables that were significantly related to the realized standards included homeowners’ attitudes and knowledge about building energy efficiency standards and the age of the respondents. Although the homeowners who were surveyed were initially satisfied with the selected energy efficiency standard, many now indicate a preference to implement significantly higher energy efficiency standards than those achieved in their project. Further, they would recommend even significantly higher energy efficiency standards to friends than the standards preferred for their own house. These findings suggest that current preferences and communication in social networks promote higher future energy efficiency standards.

New Generation

With the 65% building energy efficiency standards being implemented, the existing external wall insulation technology will face severe challenges. The research and application of the high performance inorganic insulation materials are solicited, because the traditional organic insulation materials representative with polystyrene have some defects, such as poor fire resistance, poor durability, short service and no synchronous with the life of structure, and environmental pollution. After the big fires of the CCTV building in 2009 and the building under construction at Shanghai pudong south road NO.1 in 2010, October 8 in the morning being occurred, the new generation inorganic insulation materials represented by vitrified microsphere, are getting increasing attention. After the thermal simulation of external walls, roof, floor and windows being calculated, it is concluded that its energy-saving rate is far more than energy efficiency 50% standard, and which is close to energy efficiency 65% standard, even if taking only vitrified microsphere as the insulation mortar for outer walls of building.
