Technological breakthroughs in sustainability and energy efficency

Introduction

In the settings of both the developed and the developing world a wide range of initiatives to foster innovation mainstreaming environment supporting interventions include payment for ecosystem services organizations, sanitary energy funds, green taxes, and emerging renewable energy industry are increasing in practice. Rethink our values. This rethink of sustainability poses a challenge to individualism, by proposing instead a shift to collective benefit. But which benefits? Question arises as we should value most highly the opportunities that sustainability can offer for sharing and energy saving (for example through communal sustainability tools), reducing isolation, and increasing social capital? In response to concerns about food prices, food miles and the environment, is it more important to maximize access to good, healthy and affordable food? Britain is rigidly using the idea as of how land is used in the private sphere.

In America, community spaces mean literally that where they grow their own food and flowers in small spaces of land. Both theorists and practitioners often find discussions of style to lack the depth of more durable design considerations – for example, those that wrestle with construction, environment, and materials – that will outlast overt signatures of a specific style. In the beginning, style linked to historical eras but, during the modern age, style became a matter of choice. The freedom to choose a style of clothing, food, or architecture led research and marketing firms to begin “branding” and diffusing new products and technologies that can be “read,” or interpreted, as corresponding to a certain style. Style is now an indication of taste rather than of historical location.

Sustainability development and design

Efficiency in construction could take delivery of a substantial boost from standardization, modularization and prefabrication. The standardization of components brings many benefits, including a reduction in construction costs, fewer interface and tolerance problems, greater certainty over outcomes, reduced maintenance costs for end-users, and more scope for recycling. Modularization adds to the advantages of standardization, by increasing the possibilities for customization and flexibility, and helping to realize the potential of prefabrication in a factory-like environment. Prefabrication would increase construction efficiency, enable better sequencing in the construction process and reduce weather-related holdups; by such means, it becomes possible to reduce a project’s delivery times and construction costs relative to traditional construction methods, and also to create safer working environments.

Prefabrication can be applied in a wide variety of project types, ranging from residential housing to large-scale industrial plants. The various systems can be distinguished by their degree of prefabrication: at the simpler end are the mostly two-dimensional building components, such as walls, ceilings or truss elements; then at hand are also the modular structures, comprising larger volumetric elements like entire rooms or story’s and finally, there are entirely prefabricated assets. The degree of prefabrication is based not just on these physical dimensions, but on a further factor as well: the integration and complexity of mechanical, electrical and plumbing systems. Few examples have been enlisted below:

  • BASF and Arup have mutually established an app for architects, engineers and project holders to calculate the energy saving achievable from the latent-heat storage system Micronal. Given the multiple-stakeholder nature of construction projects, it is essential to improve collaboration and knowledge transfer among contractors, subcontractors and building material suppliers both strategically and on a project basis. For optimal innovation and better uptake of ABMs, what’s needed is a concerted effort on the part of the industry as a whole, for instance, via industry-wide standards and certifications as well as an active role by governments, in establishing innovation friendly policies and procurement processes.
  • Fluor has built up an internal team of experts on concrete to advise the client at an early planning stage, to develop a foundation of data based on experience and to create a convincing business case for greater use of innovations (such as 50%-faster-curing concrete) in the market.

Energy saving in architecture base

The supply of the resources is as much a function of the global economic market as it is of individual ambitions; therefore, assumptions about future fuel scarcity and increased environmental costs directly impact present-day design decisions. If an architect believes that, in the future, energy will be more expensive, more difficult to obtain, or both, these considerations will feed into her designs if she wants her work to remain viable into the future. However, market prices are not the only factor at play. Buildings are ultimately constructed with an end user in mind. The anticipated energy consumption of the future inhabitants also strongly influences building design, and in addition to considering for whom they are designing, architects and engineers must also consider how these occupants will make use of the building, whether it is for retail, hospitality, or offices.

The perception of smart building is an acquisition of popularity. This is in part due to technological advances, which are driving down the cost of sensors, data storage and computing services. At the same time, potential customers are showing increased interest, attracted by the widening adoption of connected devices, and are demanding greater energy efficiency in buildings and improved safety and convenience. As for the owners or end-users of buildings, they stand to gain several benefits: reduced operating costs, through a likely 20-40% reduction in energy usage; greater comfort, thanks to improved lighting and temperature controls, for instance; and increased operational efficiency, partly by means of remote servicing.

  • For example: Skanska and its partners are pioneering the wireless monitoring of buildings, using sensors to record data (such as temperature and vibration), and wireless equipment to store and transmit this data. Data analytics are applied to determine the implications of any changes in the sensor readings. These smart-equipment technologies have the potential to reduce unexpected failure by 50%, improve building-management productivity by 20-30% thanks to less need for inspections, and improve the building’s energy saving by improving the performance of 10% over its lifetime.
