A green building is designed and constructed with a focus on minimizing its environmental impact throughout its entire life cycle. To design a postive impact green building following attributes can be useful: ~ Renewable Energy Capacity installation and exploring selling excess green to other entities using renewable wheeling route. ~ Energy-Efficient Design, geometry and appliances with real time monitoring and control using SCADA. ~ Green Roof and Walls to improve insulation, reduce energy consumption, and maintaining ambience. ~ Waste heat Recovery Systems like heat exchangers to capture and reuse energy in for e.g canteens that would otherwise be wasted. ~ Ground water recharge by rainwater harvesting structures.

A proper site assessment will lend itself to detailed evaluation of materials, passive energy, and future improvements required to achieve a net positive energy load. The elevation, average climate, shading or lack thereof, and on site conditions may dictate which building materials will last longer and be more efficient, given the conditions. E.g., ICF blocks vs standard framing with blown insulation. Natural cooling and passive heating have a great deal to do with building orientation, window placement, venting, and roof line design. All of these are impacted by the location on the earth for the site. Future improvements in appliances, smart sensors and panels, RE (e.g., solar), will all be impacted by the design of the building.

The site analysis determines the optimal combination of passive and active systems. Passive systems, such as shading and control of solar access, are designed to minimize the energy demands of a building on site. Operating systems that are active such as HVAC, lighting and energy management systems are designed to enhance the energy performance of the building. Site analysis ensures that the building's design is compatible with site requirements and optimizes energy production while identifying any potential limitations. This analysis ensures the selection of the most effective renewable energy systems for the site. The renewable energy systems, such as solar PV or wind turbines, are then integrated into the design of the building.

The choice of building materials can significantly affect the sustainability of a building. Sustainable building materials can improve the energy efficiency of a building, reduce its carbon footprint, enhance indoor air quality, and minimize waste during the construction process. Additionally, by selecting materials that can last for a long time, the building's life can be extended.By using sustainable materials, the energy efficiency of a building can be improved. Sustainable materials like insulation, energy-efficient windows, and high-performance roofing can help keep buildings comfortable while reducing energy consumption. This decreases the carbon footprint caused by the energy production for the building.

Choosing efficient materials is a critical aspect of building design for energy efficiency. In particular, materials with insulated properties to control heat loss or radiation into the building plays a big role and minimizing the energy energy needs of the building for occupant comfort. Lighting is typically another large user of electrical energy at typical building. Using the most efficient lighting methods is critical. Finally, the ability to efficiently use the sun as a source of heat is another opportunity to enhance energy efficiency.

Yes, and by considering the options for the building, either with retrofit or for new build, this is entirely possible. Consider who will use the space and what they will need. Design accordingly to support the energy services that are needed and then consider climate and climate resilience. Then look at the roof space first of all, how much PV can you fit? Monitor and manage and ensure batteries are part of the mix. Either with an EV or a battery unit in the building.

Crafting a green building that surpasses energy consumption involves a holistic approach. Integrate renewable sources, like solar and wind, prioritize energy-efficient design, and employ advanced technologies for real-time monitoring. Smartly utilize green roofs and walls, implement water conservation for indirect energy savings, and assess materials for sustainability. Explore community energy sharing and adhere to recognized certifications. Such an integrated strategy not only minimizes environmental impact but positions the building as a sustainable energy contributor.

Transforming a building into self-sufficient energy requires optimizing the fa?ade, windows, and insulation to minimize heat loss and gain. Invest in energy-efficient appliances and embrace automation for smarter energy use. Use the power of nature! Harness the sun with rooftop solar panels, capture the wind with strategically placed turbines, or tap into the Earth's core with geothermal systems. Even flowing water can become a building's mini hydroelectric power plant. Think of storing excess energy in batteries for later use, or become a good neighbor by contributing to a community microgrid. This holistic approach empowers the building to not only meet its own needs but potentially even contribute to a cleaner, more sustainable future.

The best decision my parents made was to design the house from east to west. This helps to get the maximum amount of sunlight throughout the day. This means that from sunrise to an hour before sunset, we do not require switching on a single light inside the house. Another feature is using large sliding windows that allow maximum light to enter the house during daytime. The 3rd feature is having both the 40W LED tubelights and 9W LED bulbs which helps us to choose between the amount of light we need during night time. By my own estimation, this has helped us reduce our electricity consumption anywhere between 40 to 60% compared to a house with conventional design and lighting.

A passive design will not only make the building energy efficient , but also comfortable for the occupants. It starts with understanding the building orientation and the location's weather patterns and taking a data driven informed decision of the right passive design feature.

The best reduction in carbon emissions is achieved through the emissions you never emit. Historical architecture is filled to the brim with examples of nature guided structural elements that maximize the use of naturally available resources to achieve comfort inside a built structure. E.g the use of a strategically placed water body and Venturi effect to cool the air entering the building located in a desert climate as seen in the "Hawa Mahal" in Jaipur, India.

For many years the importance of water has been neglected, and for a long time, conditions have not been created to manage it accurately. Today, water management issues can rely on technological solutions that make it possible and accessible. However, it is necessary to change the approach and consider that, unlike in the past when it was thought that buildings could only consume water, now it must be considered that every building is also capable of "producing" at least part of the water it needs. And the first and most important method to follow is to avoid any form of waste.

Here's the most important steps of all, "user engagement." Employees must be motivated and taught about various sustainability initiatives taken by the organisation to build the structure. - promote energy-conscious behaviors through education, monitoring systems, and interactive displays, fostering a sustainable mindset. - User involvement enhances overall sustainability by encouraging responsible resource use and reducing environmental impact.

You can design and build the ‘snazziest’ best in class buildings but its unlikely to realise its full potential/deliver all it can without engaging with the end user and thinking about behaviour change along the way. I always think about my old super efficient office with its very sophisticated heating and ventilation system - when staff realised they could open the windows on their floor they did…negating the whole design. Engage with and educate the end users from the start if possible and I think it pays back.

Engaging and motivating people is the most important factor of change in the energy management of a building; the available innovative technologies are a fundamental enabling factor, but change occurs when people are actually in the condition to use technologies in the best and most responsible way to manage energy as a primary resource.

Use of solar wind power, algae and microgreens can be solution, saving power mindset also should be there. Plat trees like terrace garden, kitchen garden, backyard garden, day lighting, solar cooker, switching to EV for transport.

While the building itself may have green design, the impact of contractors and their supply chain can still affect the overall sustainability of the project. If they do not adhere to eco-friendly practices, it can undermine the green credentials of the building. A truly green building considers not only the design and operation but also the entire lifecycle of the building, including construction. Therefore, it's essential to ensure that contractors and their supply chain uphold environmentally responsible practices throughout the construction process and following standards such as LEED or BREEAM. Only then, a green design building can truly be considered a green building.

While the preceding 6 points are all important, ultimately whether a green building is able to generate more energy than it uses is an equation between the building's energy generation and its energy consumption. From a decarbonisation viewpoint, the most sustainable form of energy is the energy that we do not use, hence demand reduction and energy efficiency stands at the top of the hierarchy of measures here. Depending on the energy demand use cases specific to the building, there are more that can be done. Take the use of heat pumps instead of gas-based heaters for example. If the building houses data centres, then enhancing the PUE would grant energy reduction benefits. Consider also the rightsizing of HVAC and other infrastructures.
