2. Issues to be solved in preliminary stage
Phenomenon like lack of drawings, uncertain building quality etc. commonly exists in existing buildings. Before the refurbishment, diagnosis is carried out by using the technologies, including building 3D scan technology, regional aerial technology, site investigation, surveying and mapping and monitoring etc. and simulation analyses regarding regional wind environment, building energy consumption and luminous environment are carried out through establishment of building information model (BIM).
Existing buildings are commonly under the conditions that it is difficult to use the new energy-saving technologies due to the narrow space, old infrastructures together with policy restrictions on refurbishment of existing historical building. The project lays particular emphasis on meeting requirements of energy-saving standards through adoption of passive energy-saving technologies like natural ventilation, variable building envelope and natural lighting etc.
3. Innovation and improvement
Construction model innovation: adopts DOT (Design - operate - transfer) business operation model, with green concept throughout the whole process of planning, design, construction and operation.
Refurbishment technology innovation: adopts greening technical strategies of tailored measures and passive technologies as principal, so that the energy consumption per unit area is reduced by 24.3% comparing to similar buildings in Shanghai city.
1. Resource sharing and green transport
Open space: Green E Park public areas are open to public and the recreation square is designed in combination with landscapes so that the places for activities and communication space for public are increased.
Sponge park: Based on the local conditions, adopts rainwater low impact development technologies. Increases the field rainwater infiltration and natural cyclic utilization through a number of runoff control measures like permeable pavement, grass swale, rainwater garden, low elevation greenbelt and landscape pool etc. And reduces the pressure on urban water supply and drainage through adoption of reclaimed water treatment equipment with capacity of 20 tons/day.
Green transport: Leads green travel with bicycle parking facilities on the ground level and rational allocation of public traffic system and slow-moving traffic. Equips parking lot with solar charging stations and encourage public to use electric new energy automobile so as to reduce carbon emission from transport.
2. Comprehensive utilization of passive energy-saving technology and renewable energy
Renewable energy: Based on local climate and natural resources, comprehensively utilizes a number of passive energy-saving technologies and renewable energy. Utilizes roof frame to install solar photovoltaic power generation system and set up centralism solar energy hot water system. Landscapes are equipped with solar street lamps for lighting at night.
Passive energy saving: saves energy consumption for underground space lighting through rational allocation of optical lighting system. Adopts technologies, including variable building envelope design, three-dimensional afforesting and building self-shading etc., which promote the indoor natural ventilation. With the open able windows area reaches 51% and the total green area reaches 1207.76m2, the natural cold sources are fully used in transition seasons.
3. Intelligent management system
Green E Park has an intelligent management system, which can real-time monitoring building energy consumption, sound environment, thermal environment, pollutant concentration etc.
If you had to do it again?
1. Parking and surrounding transport issues
The project refers to reforming old industrial plant to green innovative industrial park, which is sure to cause significant increase in commuting traffic and parking lot. However, as the project locates at old industrial urban area, it is difficult to satisfy the traffic demand after refurbishment due to the congested road and limited space. Therefore, the project adopts bicycle parking lot and electric periodic-lease vehicles to connect to subway and public transportation resources around so as to reduce the demand of travel with private cars.
2. Municipal water supply and drainage issues
The water logging is serious in the area due to the incomplete surrounding municipal water supply and drainage facilities. The project increases the field rainwater infiltration and utilization of rainwater/reclaimed water and reduces the pressure on urban water supply and drainage through adoption of rainwater low-impact development technologies and reclaimed water treatment equipment based on the local conditions.
3. Historical building protection issues:
Built in 1926, the project comprises historical features protection buildings so that the reforming of building envelope is subject to strict restriction by historical building protection regulations. It is not allowed to apply external thermal insulation and shading facade reforming in large scale. Therefore, the project solves the issues of sun shading and thermal insulation through increasing middle corridor and setting up non-air-conditioned area etc. on the basis of reserving existing industrial building legacy as possible.
