People frequently claim that finding smart solutions to problems requires a creative approach that involves thinking outside the box. This premise has become a widely accepted idea in the field of technology, where numerous historical breakthroughs have emerged from innovative methods. Prominent examples in power generation include the discovery of the photovoltaic effect by Edmund Becquerel in 1839 and the development of the first commercial solar panel by Charles Fritts later that century. These milestones have enabled the integration of solar panels as essential components of clean energy generation within architecture, driving a significant shift toward renewable energy.
This shift is currently manifesting as a tipping point between power generation and the built environment, driven by a transition that promotes creative thinking and encourages new perspectives. Today, sustainable energy production extends beyond merely installing solar panels on roofs; it aims to integrate various building elements into the energy system. ClearVue's Building-Integrated Photovoltaics (BIPV) exemplifies this innovation by harnessing nearly all facade components as sources of power production. This vision opens new possibilities for the design of urban structures, promoting a more sustainable approach that aligns with contemporary needs.

A historic symbol of the industrial age, the sawtooth roof is a lasting legacy of architectural history. Although a functional invention born from necessity nearly 200 years ago, the iconic shape is enjoying a renaissance in many contemporary projects.
Made up of many long, thin roofs with irregular pitches laid alongside each other, a sawtooth roof positions its steeper edges – filled with glass panels – away from the equator. This allows large buildings to control their solar gain by omitting direct sunlight, while still allowing uniform indirect natural light to fill an entire interior area.
The sun’s influence on human life encompasses multiple dimensions, from biological and developmental aspects to religious-mythological connotations in civilizations such as the Egyptians and Romans. Moreover, this influence extends to its use as a natural resource within the realm of science. In scientific pursuits, the continuous search to harness the sun as an energy source has been a constant throughout the years. Within this context, the discovery of the photovoltaic effect and its application have paved the way in the history of solar panels, starting from the first observations of Becquerel to the initial prototypes of Charles Fritts in the 19th century.
Nowadays, the energy obtained from the sun through devices such as solar panels has become one of the most widely used sources in regions like North America and Europe, contributing to the efforts for a complete transition to clean energy. The momentum in this transition has motivated the development of new technologies, such as SolarLab facade systems, that challenge the preconceived idea of what a solar panel looks like and where it can be installed. These systems converge with architecture to integrate them as aesthetic elements, serving as cladding for both retrofit projects and new buildings.

Renovations involve design processes that transform, refurbish and enhance architectural elements. From gentle aesthetic changes to structural additions, building renovation can improve functionality, safety, and energy efficiency. By integrating new technologies, contemporary strategies are giving new life to existing buildings, propelling already-built projects into the future.
Through their energy-efficient, durable, and bespoke solutions, SolarLab leverages architectural heritage by introducing custom energy-producing facades to existing buildings. By seamlessly combining technologies with design freedom, these solar facades adapt to each project’s style while acting as rain screens with a long, maintenance-free service life. Moreover, by producing sustainable electricity, integrating this system into refurbishment projects contributes to the building’s day-to-day operations, effectively reducing its environmental impact.
Diamond Schmitt and MVRDV have unveiled the design for a new building for the Scarborough Academy of Medicine and Integrated Health (SAMIH) at the University of Toronto’s Scarborough Campus. The new addition, featuring laboratory spaces, classrooms, and offices, aims to function as a communal and gathering space for the community. The functions are distributed around a five-story atrium that opens toward the exterior on both sides of the building and establishes a destination point within the pedestrian flows of the campus. Solar panels integrated into the façade help power the building, while the warm finishes of the interior contribute to creating a welcoming atmosphere.
Every year since its establishment in 1970, Earth Day aims to bring into focus not only the increasingly threatening effects of climate change but also highlight the effective measures and adaptation efforts that can improve the quality of our environment. This year’s event comes after a report from the United Nations’ Intergovernmental Panel on Climate Change (IPCC) in March, which presented another warning on the magnitude of changes produced by human-induced global warming and its impact on people and ecosystems. The same report does offer some hopeful prospects as well, showing that adaptation measures can build resilience, but those urgent systemwide transformations are needed to secure a net-zero future. In response to these findings, the 2023 Earth Day is focused on the theme of “Investing in Our Planet,” as an encouragement for governments, institutions, businesses, and civil society to accelerate the change. Read on to discover several citywide initiatives aligned with these objectives of building resilience and a more sustainable future through legislation, civic involvement, and innovative systems.
Sunshine has been an integral part of life ever since the sun and the earth began their merry dance. The feel-good ambiance provided by natural light is a recurring theme in human culture, from popular music, fashion, and photography, to our most luxurious environments.
But our bodies’ craving for sunlight is more than just a feeling. Scientific research has proven it helps our bodies to produce more melatonin which aids sleep and reduces stress, vitamin D which improves immunity and strengthens bones, and serotonin which fights depression. As well as helping us to live healthier and happier lives, research suggests the sun also helps us to live longer, too.
The Het Nieuwe Instituut in Rotterdam, The Netherlands, opens The Energy Show and the Solar Biennale on Friday, September 9, 2022. In collaboration with The Solar Biennale designer and curator Matylda Krzykowski and solar designers Marjan van Aubel and Pauline van Dongen, the exhibition presents a series of projects that explores the sun's meaning and possibilities in society, the environment, and design. With Europe in the midst of an energy crisis, The Energy Show and the Solar Biennale is an opportunity for designers and the general public to examine the transition to solar energy and technology as we move towards a post-carbon future.

Climate change remains a foremost concern in global politics, economics, and scientific research, particularly as it pertains to the architecture and construction industries. This heightened culpability for the field of architecture stems from the fact that the construction industry contributes to 40% of global emissions, and the demand in the building sector is only projected to increase by 70% by 2050. Renewable energy is part of a 21st-century sustainability paradigm that responds to climate change and environmental degradation, strengthening the momentum for global energy transformation. Renewable energy production strategies are necessary to mitigate future energy security issues as traditional sources of fuel become increasingly scarce, and an indispensable part of designing for sustainability in architecture.

Solar design in contemporary architecture is rooted in the profession's sustainable turn. The relationship between architecture and energy is tied to both passive strategies and performance via more recent innovations in technology. As one way to begin addressing the global climate crisis and greenhouse gas emissions, solar design is reshaping cities and architecture around the world.
UNStudio has just completed the remodeling works of the Hanwha headquarters building in Seoul, while the building remained fully occupied. The refurbishment operations have created a modern establishment that meets the current sustainability requirements.
Solar tiles operate identically to the photovoltaic panels that are already widely used in construction. The primary difference between them lies in their assembly: whereas photovoltaic panels are attached to an existing roof, solar tiles are part of the roof's construction from the start, taking the place of regular tiling.
The tiles are formed by photovoltaic cells that, when they receive sunlight, create an electric field capable of providing electrical energy for use inside the building. Each tile is connected by cables to the power distribution board.
On November 13th, 2019, a new train station was inaugurated in the city of Matera, Italy. The project, a new building and future park designed by Stefano Boeri Architetti, represents an important link between the city’s old town, post-war and modern districts and a key point of access to the city of Matera in the year that it’s set to become the European Capital of Culture.
The California Building Standards Commission has approved a new rule starting in 2020 that requires all new homes built in the state to include solar panels. As the first of its kind in the United States, the new rule includes an incentive for homeowners to add a high-capacity battery to their electrical system. The move hopes to help meet the state's goal of sharply reducing greenhouse gas emissions while drawing all electricity from renewable energy sources.
When it comes to increasing the energy efficiency of a project, solar panels provide many benefits, but architects often avoid using them for aesthetic reasons.
Today there are alternative solutions for adding solar receptors to the individual elements that make up the roof—the zone of greatest exposure to sunlight—that are less conspicuous and very effective in terms of energy production. One such example is solar thermal panels, which use the power of the sun to heat the building, produce hot water or generate heat for pools.
These new panels are made from natural slate stone, in formats ranging from 32x22 cm to 50x25 cm. The material elements not only ensure thermal inertia and impermeability, but are also able to heat up to 50 liters of water per day per square meter of surface -- all while avoiding the average emission of 90 kg of CO2.

A new challenger has stepped into the ring of home solar batteries, and it’s a name you may recognize: global furniture retailer IKEA.
A competitor to Tesla’s now-available Powerwall home battery and solar roof system, IKEA’s home battery will be first sold in the UK, where owners of solar-powered homes can typically only sell excess energy produced back to the national grid at a loss. The battery pack will instead allow that power to be stored for later use, helping homeowners reduce their electricity bills by as much as 70 percent.
