Sustainable building

Finding a site to construct a sustainable building is not an easy task and persuading a developer to commission one that utilises all the latest RE technologies and design techniques can be even harder. This is where businesses, research institutes and anyone else who is involved in the renewable energy sector can be very helpful. After all, if even those who are involved in the green economy will not support the concept of sustainable building then who else will? In this issue of Sustainable Building we focus on one such example where a R&D Centre in Germany the Fraunhofer Institute for Solar Energy Systems (ISE) has commissioned and opened a new sustainable headquarters in Freiburg, Germany.     

Developments of Green Building Standards in China

There are 17 green building standards (including those under development) at country level and another 50 or more at provincial level in China. Based on background and status overview of green building standards, problems are analyzed. It is followed by a systemic scheme for green building standard system, which includes 3 layers of basic, general and specialized standards, and its development planning as well. Some suggestions are proposed for green building standards development in this paper.     

Impact of voluntary green certification on building energy performance

Credible estimates of energy savings from green buildings are critical for policy makers to examine the cost and benefit of various incentives intended to encourage commercial buildings to go green (e.g. expedited construction permits, government grants, and property tax incentives). Yet, data limitations have hindered reliable estimations. Filling this gap, this study uses a large panel dataset on energy consumption for commercial buildings in Phoenix metropolitan area, Arizona. By tracking building occupants' monthly energy consumption before and after the building's certification as an Energy Star building, we provide new estimates of the environmental gains from private investment in green real estate. Results show that for occupants that occupy space in a certified building in both the pre-certification and post-certification periods, occupants in Energy Star buildings consume 8% less energy. This empirically robust estimate of potential benefit from green-certification provides a quantifiable benchmark against which green-promoting policies can be measured. We also document evidence of heterogeneous treatment effects. Energy savings differ by the building's initial certification points and the building's baseline energy consumption. These results are useful for policy makers to identify targets for green certification.     

Design optimization for the hybrid power system of a green building

This paper proposes an optimal design procedure for a green building equipped with renewable energy, energy storages, and proton exchange membrane fuel cells (PEMFCs). First, we introduce the hybrid power system of the green building and construct a simulation model using Matlab/SimPowerSystem?. The model parameters are tuned so that the system responses can be estimated without extensive experiments in the optimization processes. Second, we define the cost and reliability indexes to optimize the system design using three steps: component selection, component sizing, and power management (PM) adjustment. We further define the safety index to evaluate the system's sustainability under extreme conditions when no renewable energy is available. Last, we apply the proposed procedures to the green building and demonstrate the benefits of the optimal design. The proposed method can be directly applied to develop customized hybrid power systems in the future.     

我国房地产企业开发绿色建筑的现状和启示

Analysis of photovoltaic-green roofs in OSTIM industrial zone

In the current century, climate change, air pollution, and the depletion of energy resources are big threats to our society, especially in urban areas. It is an inevitable fact that we need to develop the green building concept and produce innovative solutions in our quest to design structures that are compatible with nature, sustainable, environmentally friendly, aesthetic and use natural resources efficiently. Roofs are the most efficient and promising building surfaces for the combination of photovoltaic panel applications and green roofs considering their locations and inclination angles. This research focuses on how carbon emission can be reduced via both green roofs and solar energy while producing electricity in OSTIM, one of Turkey's most prominent industrial zones located in the capital. The long-term detailed analysis of photovoltaic-green roof application in terms of economics and carbon emission is discussed. Although the rooftop option of a combination of solar panels and a green roof design costs higher than a standard photovoltaic system, it opens up new prospects for urban lighting in smart cities with exciting aesthetic effects. This combination of two sustainable features can become a model of green technology and opens up a wide range of research applications.     

Experience on integration of solar thermal technologies with green buildings

The green buildings of Shanghai Research Institute of Building Science include an office building for the demonstration of public building and two residential buildings, which are for the demonstration of flat and villa, respectively. Here, a solar-powered integrated energy system including heating, air-conditioning, natural ventilation and hot water supply was designed and constructed for the office building. However, only solar hot-water systems were installed for the flat and villa. All the three solar thermal systems have continuously run for 2 years. Two different integrated approaches have been put into practice in the two green residential buildings. It is shown that, for new buildings, solar collectors can be mounted on balconies and awnings besides roofs, on condition that solar systems become part of the general building design. The solar-powered integrated energy system has the advantage of high utilization ratio with different functions according to different seasons. It is testified to be capable of taking on about 70% of the yearly building load regarding the involved space under the weather condition of Shanghai.

Green building development in China-based on heat pump demonstration projects

China has been one of the biggest energy consumers in the world, while buildings in China take up over 30% of the total energy consumptions. As conventional energies like coal, oil and gas are drying up, building energy conservation and emission reduction appear to be increasingly crucial for the sustainable development of China. Chinese government has been extensively promoting the development of green building since 2004. Many researches have been carried out in this field but the overall review is insufficient. This paper aims to give a detailed review of green building development in China, and find out the defects and risks. Data of the demonstration projects of renewable energy application in building is collected and analyzed. Related policies and researches are reviewed. It can be concluded that the major defects lie in the policy shortage, technology deficiency, and market immaturity.
