New building energy-saving concepts and technology applications

writing/ LU Qiu

•  Core idea of a new type of energy-saving

•  Design Idea

It is not superficial at the onset of environmental planning to emphasize the relationship between architecture and environment in terms of aesthetics, topography, vegetation, soil and water, wind, sun and climate.

Single building designs create through the structure comfortable indoor environments that reduce energy consumption and reduce site specific emissions. This can be augmented through initially carrying out an assessment of ecology, which then impacts health, safety, geology, heritage, etc.

Planning and design using, as far as possible, the existing terrain and vegetation, solves many environmental problems, minimizing both construction costs and long-term damage costs. ?Conceived in such a manner, urban development can then be effectively and economically scaled.

Efficient use of water resources, including the control of groundwater extraction, the collection of rain water runoff, emission management and control of the permeable paving area according to minimal impact theory is also economically advantageous to urban design.

Overall layout of buildings can make use of sunshine, wind and water flow, to positively impact and improve the micro-climate and reduce the “heat island” phenomenon.

 

•  Design means passive concept of eco-building structures

Ecologically savvy architecture passively addresses urban design problems through thermodynamics, air quality, sound pollution and light design.

•  Design means passive concept of eco-building structures，

The optimal internal environment is created primarily by controlling the air temperature, indoor surface temperature, relative humidity and rate of air flow. This requires not only the use of modern construction techniques and materials, but also mechanical design to achieve residential thermal insulation in external retaining structures, eliminating cold bridges, as it were. Initial expenses in high-performance windows and doors, especially in glass products, effect positive returns over a medium term horizon as well as overall social returns in terms of cost of energy.

•  adequate fresh air was originally a residential minimum requirements，

Clean air is not just an indicator of comfort level or long term health, but because of the pollution inherent to the urban environment it should be viewed as a design element that creates efficiency, inspires creativity, and directly impacts other environmental concerns. The flow dynamics for interior ventilation require not just mechanical implementation but also engineering considerations to create passive systems for filtering dust, sand and to reduce odors.

 

•  for noise isolation，

A comfortable acoustic environment is not just an indicator of comfort level or long term health, but because of the noise pollution inherent in urban environments, it should be addressed as a design element that creates efficiency and inspires creativity in the population.? Different noise characteristics of materials as well as space design isolates noise and improves insulation.? Noise isolation directly relates to energy efficiencies insofar as airtight and insulted structures also insulate against exterior noise.

 

•  The improvement of light environment

Concerning artificial lighting increasingly prominent are such concerns a comfort, personalization, artistic taste, safety, and energy conservation. The factors that affect the light environment are not only the lighting intensity, but also the proportion of sunlight, light direction, light color, color temperature, glare and other colors. Therefore the climate and latitude are a required consideration in overall lighting design.? Furthermore, changes in interior lighting also affect population efficiency and increase the comfort of a residential light environment (Figure 06-1).

 

•  Indoor comfort of new developments in environmental research

On a global scale, residential energy saving products are experiencing two major and often opposing trends: one is technological structures to mobilize all means to achieve low energy consumption, reduce pollution and sustain development; the other is research into? into ergonomics (the human body’s interaction with the environment (light, sound, heat, air, etc.) to create healthy, comfortable and an efficient living environment.
