When the Tamina Bridge in the Swiss Alps was first proposed, the engineers were uncertain how they would create a bridge that spanned two different heights at each end of the valley, at a height of 220m (772 feet) above ground. Yet despite these challenges, the bridge was completed a year ahead of schedule in just four years – mainly due to the efficiencies that Building Information Modelling (BIM) provided. While the name may inadvertently imply that only buildings can benefit, BIM offers a host of advantages when designing and building bridges as well.

Major infrastructure interventions come with significant uncertainty – this is something explored before before. Provision of high quality infrastructure is a challenge faced by every government around the world, and there are many uncertainties around the planning and funding of these schemes that have to be weighed up and balanced.
The Enabling Better Infrastructure (EBI) programme encapsulated best practice principles from around the world. We have dipped into this best practice toolkit to underpin our review of the UK’s strategic infrastructure planning system led by the National Infrastructure Commission (NIC), the results of which we have published today.

The National Institution for Transforming India (NITI), an Indian government policy commission, has published its SDG India Index and Dashboard 2020-21 report on progress against the UN Sustainable Development Goals at the state level in India, its third annual report.
The main theme of this year’s report is ‘partnerships’, with NITI aiming to highlight the pace that can be achieved by working together in pursuit of the goals, as well as shine a light on the quiet but effective partnerships working away in the background.
As part of this, the report sets out actions that have been taken across the 11 areas of the collaborative advantage framework to drive forward progress on SDG indicators.
In the accompanying index, all Indian states and union territories are scored and ranked on each SDG, alongside progress over the year.

Most buildings, whether residential, commercial, or industrial, consume a significant amount of energy over their lifetime, whether for lighting, heating, ventilation, or plugged-in devices. Buildings consume approximately 40% of global energy, 25% of global water, 40% of global resources, and emit approximately one-third of global greenhouse gases.
The energy required to power these structures has risen precipitously in recent decades, putting an increasing strain on national power grids. This has increased the pressure to generate power by burning fossil fuels, contributing to the current climate change. This lethal cause and effect has compelled many engineers and policymakers to consider how we can reduce energy consumption in the buildings we build.
What is a Zero-Energy Building?
A zero-energy building (ZEB) is one in which the total energy used over the course of a year is equal to the amount of renewable energy produced - in other words, it produces enough energy to meet its own annual requirements. This means it does not require energy from the power grid, lowering greenhouse gas emissions. In addition to mortgage or bank repayments, utility bills are one of the most expensive running costs for these homes, offices, and manufacturing plants. So there are financial as well as environmental reasons for having ZEBs.
The scope and approach of these terms vary, but the fundamental goal of reducing energy usage, improving building energy performance, and lowering greenhouse gas emissions applies to all definitions.
Components of A Zero-Energy Building:
A ZEB has two main components: reducing the building's energy consumption and producing renewable energy for on-site use. The first key element (lowering the total amount of energy used in a building) can be achieved through the use of energy-efficient lighting systems, insulation, better water management, improved ventilation systems, and smart meters. Even changing occupant behavior can have an impact on a building's energy efficiency. The second component (on-site generation of renewable energy) could include installing solar panels, small wind turbines, or micro combined heat and power systems to meet a building's electricity, heating, or cooling needs. Any excess energy generated by the building can be transferred to the national grid, allowing the building's owners to profit from their own thriftiness.
Zero energy cities are an engineered extension of zero energy buildings. As more buildings become energy self-sufficient, communities and cities may become zero energy. This means that the total energy consumed by a city's infrastructure will be equal to the amount of renewable energy generated.
Engineering solutions that create zero-energy buildings, whether residential, commercial, or industrial, are the first steps toward achieving zero energy cities - a transition that will be critical in slowing rampant climate change and that we must now accelerate.
