Sized from the field outward: air-to-water heat pumps, RTU electric, RTU dual-fuel. Performance curves at low ambient, refrigerant transitions (R-454B), and TCO modeling.
For a 100-ton commercial rooftop replacement in ASHRAE Climate Zone 5B, when does dual-fuel (heat-pump + gas backup) win on 20-year total cost of ownership versus all-electric heat-pump? The math depends on utility rates, refrigerant choices, and BPS exposure. Here's the model and where the breakpoints actually fall.
By Eleen Korir In the global effort to combat climate change, reducing carbon dioxide (CO₂) emissions is a top priority. For organizations and building owners, one of the most effective ways to cut emissions and reduce energy costs is through energy audits. Energy consumption and CO₂ emissions are…
By Mary Korir In recent years, the conversation around energy use in Kenyan facilities has evolved from simply monitoring consumption to actively managing it. Real-time energy data are powering this transformation and it’s changing the game for organizations seeking efficiency, cost savings, and…
Choosing an energy monitoring system can be overwhelming, but making the right choice can lead to significant savings, increased efficiency, and a reduced environmental footprint. This guide breaks down the essential steps for picking a solution that works, whether you're managing a home, a…
In today’s fast-changing business environment, energy efficiency isn’t just a buzzword, it’s a game-changer. As more organizations look to cut costs and operate sustainably, adopting energy-smart practices has become a powerful strategy to boost performance, reduce expenses, and shrink…
By Mary Korir In today’s rapidly evolving world, the demand for energy is higher than ever before. As countries globally push toward sustainability, energy efficiency has become a critical focus—especially in developing regions like East Africa. Traditional methods of energy management no longer…
By Karen Thuranira In today’s fast-paced industrial and commercial environments, energy management has evolved beyond simple cost cutting measures and into a strategic imperative for growth and sustainability. Rising energy prices, growing environmental regulations, and increasing corporate social…
By Ruth Carol Atieno If you've been looking for an energy-efficient way to keep your home warm in the winter and cool in the summer, you may have come across the term heat pump. But what exactly is a heat pump—and how does it work? In this blog, we'll break it down in simple terms, [...]
By Kelvin Musyoki In the pursuit of sustainability and cost reduction, energy audits emerge as indispensable tools for organizations seeking to optimize energy consumption and bolster operational efficiency. Conducting an effective energy audit entails a meticulous blend of technical expertise,…
By Ruth Carol Solar photovoltaic (PV) systems have emerged as a promising and sustainable solution to our ever-growing energy needs. They harness the power of the sun to generate clean electricity, reducing our reliance on fossil fuels and mitigating the impact of climate change. However, to make…
By Kelvin Musyoki My journey to the energy space might have started when I stumbled upon a proposed final year project on renewable energy. I was an undergraduate Mechanical Engineering student almost bolting out of campus with a desire to practice Mechanical Engineering. I was prepared to crown…
By Cherrily Shikweya The Paris Agreement, adopted at COP 21, requires its member countries to commit to reducing their greenhouse gas emissions, hence limit global warming to a temperature increase below 2ºC, and preferably 1.5ºC. One way countries can cut down on global emissions is by adopting…
By Ruth Carol Atieno The AcuRev Power and Energy Meter is used for real time metering. It measures the energy consumption of a facility, multi-tariff time of use and also monitors power quality. The recommended option for facility managers who monitor trends, produce analysis and create reports…
By Ruth Carol Atieno Planning early will allow you that mind and body relaxing vacation that you have been dreaming about. How about for a change, you target an energy efficient vacation? Saving your body's energy and also in the long run saving electricity. First things first, how about I show…
By Ruth Carol Atieno The best thing about Fluke Infrared (IR) Thermometers is that you do not have to be in close range with the point of measurement. You won't get burns from a furnace or have cold air from a cold room blowing all over you. with an IR you can get the measurement [...]
By Ruth Carol Atieno COOLNOMIX In recent years, with the planet becoming either hotter or cooler than expected, Air Conditioners (AC) have become a basic necessity in our homes and offices. Those not in a position to afford the ACs resort to other cheaper traditional solutions. Refrigeration has…
By Chris Mbori President Uhuru Kenyatta recently (March 12, 2019) signed the Energy Bill 2017 ushering a new era in the energy space in Kenya. Being in the energy efficiency market, I have looked through the new Energy Act 2019 and found three interesting highlights to share. 1. The Energy Saving…
After 1 year in energy management By Warren Ondanje I joined Eenovators back in March 2018 as an intern, after an adrenaline-pumped interview I thought I’d asked a little too many questions. Coming from a Chemical Engineering background, half the interview questions had me turning pale – you know…
By Warren Ondanje. It is highly likely that your weekly errands involve visiting a store housed a mall. In Nairobi especially, standalone shopping stores are becoming fewer as investors are betting on adding to the already-present 30 malls. From the convenience of having many shops in a single…
By Ombajo Vincent Gedion Is Solar Thermal Kenya's next ready frontier for Energy Efficiency? For something to grow and be acceptable in large scale, a lot of work and time go into it. In the world of clean energy, a combination of factors that range from ideology, opportunities, needs and…
By Kelvin Odhiambo Securing access to modern and sustainable energy services for developing economies is a significant challenge for development. Access to sustainable energy services can power opportunities for environmental, social and economic development. Energy costs for most facility owners…
