EPC+

EPC stands for Energy Performance Certificate, which has become a vital rating scheme to summarise the energy efficiency of different buildings. The drawback of EPC is that the ratings and suggestions are based on assumptions instead of fact

Route to Net Zero

Becoming carbon neutral is not only good for the environment, but it can also affect your profitability. 

While tracking and controlling the current and future carbon emissions and becoming Net-Zero is the destination for businesses, it is not easy to find/identify a clear, practical route to achieve this goal.

Our ‘Route to Net-Zero’ service provides clients who wish to adopt a net-zero carbon philosophy for their business with a holistic approach to managing their short-term carbon footprint reduction targets and the long-term transition to net-zero carbon. The service includes measuring the business impact on the planet and establishing carbon-reduction frameworks and strategies to optimise their operations.

We help businesses develop strategies in line with the 1.5°C future to limit the impact of climate change on the planet and will provide support and high-quality independently-verified climate solutions to balance out residual emissions by the business. We can help our client with three types of validation: self-validation, validation from the non-accredited organisation, and independent third-party validation.

Heat Pumps

One of the main sustainability solutions that we offer is heat pumps, which is a low-carbon alternative for heating your home or business space by using electricity to generate heat rather than burning gas, whilst you can save on your energy bills. As the name suggests, air-source heat pumps use the heat in the air, water, or ground. There are multiple types of heat pumps, but the main two are air source and ground source heat pumps.

 

Solar Thermal & Building-Integrated PV Systems

Several solutions, such as “solar thermal,” can be used alongside or instead of solar panels. Solar thermal uses the heat produced by the sun to heat water within the house’s heating system, storing hot water ready for use.Building integrated photovoltaic systems encompass a range of different solutions, among which CASL and its partners specialises in.

Here at CASL, we can assess your house or business using your current usage and Artificial Intelligence (AI) to determine which combination of solar panels, thermal systems, or building-integrated systems is best for your individual needs.

Smart Controllers

Smart home and building products, or innovative systems, are becoming more common and are offering significant energy and water savings compared to manually controlled systems. The essential components of these systems are the controllers, or programmers, like the system’s brain. These can be connected to and synchronised with your boiler, heat pump, radiators, lamps, rainwater harvesting systems, and other energy and water appliances.

Our team offers tailored smart controllers for each customer, using Artificial Intelligence (AI) and the Internet of Things (IoT). For small settings, we often provide smart thermostats and/or TRVs which easily enable the user to control the temperature of each room. These smart-systems can be connected to different types of radiators and can have an interactive LCD/LED display on the body of the radiator.

Grey Water Recycling (GWR)

Greywater refers to any domestic wastewater produced, excluding black water (wastewater produced in the toilet). Black water contains a very high amount of organic matter compared to greywater. The proportion of greywater to the whole household wastewater varies depending on household characteristics and water use habits, but it is generally about 40 to 70% of a household’s wastewater. 

Our team designs smart GWR systems powered by the Internet of Things(IoT) and Artificial Intelligence (AI); the smart GWR will consume much less energy than existing GWR systems in the market. It also helps direct the treated wastewater for reuse in different parts of the building when needed.

 

Smart Rainwater Harvesting

Rainwater harvesting refers to capturing and storing rain that falls on the roof of a building, usually in containers called water butts. In areas of high rainfall, the amount of rain captured is vast, particularly in buildings with large surface areas, as many businesses do. In a simple system, this water can be manually taken to the required places, such as for watering plants in a home. When filtered and connected to a treatment plant, the rainwater can be used for more practical applications such as laundry and toilet flushing.

Train wash and car wash recycling

With the help of innovative technologies, this system allows you to re-use your entire commercial wastewater (from carwash or train wash) and enables you to capture savings while actively helping to preserve the environment. 

Wash water is treated utilising three key stages. Heavy solids are firstly settled using an intensive sludge interceptor. Secondly, the water is passed through a cyclonic filter and activated granular carbon vessels to remove any organic compounds or chemicals.

 

Solar-based and low-energy water treatment systems

Solar-based water treatment systems have a wide range of applications in both the residential and commercial sectors. The scalability of the size of systems means that this could be used in any building, from small residential houses to large hotels. All the systems can run directly off solar panels and do not require a grid system to be in place; there are significant applications for remote areas which operate as a microgrid. This can generate clean drinking water or treatment of wastewater that would otherwise cause a health hazard.

Smart Water Dispensers

Water coolers and dispensers in public/work settings have been removed, taped off, or unused due to the risk of cross-contamination (spread by touching). This issue was significantly deepened during the pandemic and the increased risk of Covid-19 transmission.

CASEL has developed a state-of-the-art patented water dispensing system to drive consumer health and safety. This smart technology can be called “the next generation of water dispensers.”

Smart Solar Panels

High ambient temperatures have several negative impacts on the performance and efficiency of PV cells and panels.

CAESL has developed an innovative thermal absorber heat exchanger that can improve the performance and efficiency of PV panels significantly. This patent-protected innovation can be easily installed into the space behind any standard solar panel and includes a smart controller system with a powerful optimization engine that smartly controls the performance of the heat exchanger.
