By 2026, the global market for net-zero energy buildings (NZEBs) is expected to reach $47.4 billion.

Buildings’ energy intensity, defined as the amount of energy used by buildings, would need to improve by 30% globally by 2030 in order to meet the Paris Climate Agreement’s aims, the key goal of which is to keep global average temperature rise to 1.5°C. While the construction sector’s energy intensity continues to improve at a 1.5 percent annual rate, the roughly 2.3 percent increase in worldwide floor area has countered some of these gains. If no scaled action is done, building-related carbon emissions are expected to increase by 2050. Read more

Scotland commits to invest to achieve a net-zero built environment.

Scottish Government is planning to mobilize £1.8 bn to cut carbon emissions from the built environment to a tune of 68% by 2030, helping the nation to realize its net zero goal by 2045. According to the Strategy, by 2030, over a million houses and the equivalent of 50,000 non-domestic structures will have to adapt to zero emissions heat. This could result in further advantages, such as the creation of 16,400 employment by 2030. According to the Strategy, between 2021 and 2026, roughly 124,000 low-carbon boiler and system alternatives would be required, with the installation rate peaking at over 200,000 new systems per year.

These strategies will help the country meet existing legislative goals, such as reducing national emissions by 75 percent by 2030, 90 percent by 2040, and ensuring that no more than 5% of households are fuel poor by 2040, no more than 1% are in extreme fuel poverty, and the fuel poverty gap is no more than £250.

Solar Decathlon India 2021-22 Challenge

The Solar Decathlon India 2021-22 Challenge enables student teams to explore affordable building solutions that are innovative and forward looking. Student teams design resilient, net-zero-energy-water buildings for real building projects by partnering with the industry. These designs have to be innovative, affordable, practical, and market-ready.

In the 2021-2022  Challenge, participants are evaluated on the following Ten Contests: Energy Performance; Water Performance; Resilience; Affordability; Innovation; Scalability and Market Potential; Health; Architectural Design; Engineering and Operations; and Presentation. The designs proposed by participants are evaluated for all Ten Contests. 

Team registration began in July 12 2021 and ends on August 19 2021. Read more

Advancing Net Zero Status Report 2021

The Advancing Net Zero (ANZ) Status Report 2021 states the achievements and endeavours of GBCs and the building and construction sector towards reducing carbon footprints. The report highlights actions from across the Green Building Council (GBC) network participating in WorldGBC’s global Advancing Net Zero project and trends & innovation on legislative and technological levels on Net zero.

One of the actions in the report included the launch of Indian GBC net zero water rating which aims to reduce water consumption and promote usage of alternate water to meet the water demand. Another highlight of achievement of IGBC was that a total of 277 organizations took pledge to work towards achieving IGBC net zero vision by 2050.  Read more

Satellite Vu raises $5m for high-resolution thermal satellite insights to support the green industrial revolution

Satellite Vu has raised a $5m seed round led by Seraphim Capital to launch the world’s first satellite constellation of miniature satellites capable of imaging the thermal footprint of any building on the planet every 1-2 hours. The constellation is enabled with high resolution IR cameras to record heat signatures of a natural and built environment located anywhere in the world. The data of the heat signatures will help to identify and implement energy efficient reforms in an energy wasting building. The constellation of satellites is due to be launched in 2022. Read more

CII IGBC launches ‘Mission on Net Zero’ on World Earth Day

ASHRAE released draft on Standard method for evaluating building performance on Net Zero – Energy & Carbon

The first public review draft on “Standard method for evaluating zero net energy and zero net carbon building performance” is released by ASHRAE on April 2021. This BSR/ASHRAE Standard 228P shall be used to identify if a site has achieved zero net energy and zero net carbon status by accounting the energy/carbon flow into a site boundary, which is to be less than /equal to the outwards energy/carbon flow during building/site operation for net zero. This standard will cover existing buildings, new buildings, groups of buildings, or portions of buildings. Evaluation with the help of this standard can identify if a site is meeting the requirements of zero net energy or zero net carbon. Read more

Net-zero emissions in India’s energy systems by 2050 highly challenging: Report

According to a recent report by TERI and Shell titled ‘India: Transforming to a net-zero emissions energy system’, India needs a suitable policy and innovation driven context to deploy clean energy technologies on a massive scale to reach a net-zero emissions energy system by 2050. It added that this would require more and faster deployment of large-scale solar, wind and hydropower to enable greater electrification across the country. The report said that adoption of economic mechanisms such as carbon trading and pricing to facilitate reallocation of capital and resources to support commercialization of new fuels and technologies and resorting to carbon sequestration to achieve net-zero emissions by 2050 would be necessary steps.
