Building Energy Efficiency

John A Herbert | Director | Kelcroft

How to improve a building’s environmental performance

It’s easy to imagine the perfect energy efficient building, but actually building it can be a lot more difficult. Every single decision has an impact on your wallet, future operating costs, and the world around you. 

Building an energy efficient facility is not natural or accidental, it has to be carefully planned in terms of design, construction, and more particularly operation. Kelcroft's background and knowledge helps stakeholders create high performance buildings in Asia.

Energy Efficiency Hong Kong

Our existing building stock is directly linked with the production of greenhouse gases and our carbon footprint. Presently, Hong Kong buildings alone account for more than sixty percent (60%) of the Hong Kong's carbon footprint!  Our buildings consume eighty nine percent (89%) of all the electricity generated in Hong Kong, and that is not sustainable.

So building improvements are an obvious target for energy efficiency improvements. Air conditioning accounts for more than 30% of the electrical consumption, closely followed by lighting. 

Benefits of Energy Efficient Buildings

The benefit of owning and energy efficient building include:

Environmental benefits:

    * Enhance and protect ecosystems and biodiversity
    * Improve air and water quality
    * Reduce solid waste
    * Conserve natural resources

Economic benefits:

    * Lower fees for tenants
    * Reduce operating costs
    * Enhance asset value and profit
    * Improve employee productivity and satisfaction
    * Optimize life-cycle economic performance

Health and community benefits:

    * Improve air, thermal, and acoustic environments
    * Enhance occupant comfort and health
    * Minimize strain on local infrastructure
    * Contribute to overall quality of life

Kelcroft helps stakeholders to help create healthier, energy efficient and more livable building environments in Asia.

"Even in tough times, and perhaps particularly in tough times customers will demand more in terms of efficiency, quality and productivity. A built environment that is sustainable economically, socially, and environmentally is the only one worth investing in now."

- Mr Paul King, Chief Executive, UK Green Building Council

Kelcroft advises architects, engineers, and building owners helping creating energy efficient buildings before the planet's resources are exhausted.

Annual MOT Roadtest

Our vehicles undergo a compulsory annual road worthiness test, yet government does not require it of our buildings. Buildings are kept operating and over time are de-tuned causing higher energy costs. Kelcroft retunes your building systems to ensure they operate at peak energy performance

Building Tuning

What is building tuning? It's a process to restore lost energy efficiency of a building. If you own a car I am sure you wouldn't consider running it for 50 years without a regular tune up, so why not order a tune up for your building today!

In addition to restoration, it also embraces new technologies, ideas, and strategies that will lower your building operating cost without impacting the service level for your tenants. 

For example, many buildings built in the 1980's use lighting and lift technologies which can now be upgraded to lower your energy operating costs. These types of energy efficient technologies were just not available at the time the building was built.


The general level of awareness in the industry is still somewhat weak, a recent survey of building professional by World Business Council for Sustainable Development. Most of those surveyed believed that buildings didnt contribute much GHG and carbon.

Energy Efficiency China

In China buildings consume twenty percent (20%) of total energy consumption, and the predicted growth will rapidly increase that to more than thirty percent (30%) before the year 2020. The number of new buildings that will be built will overshadow developing economies, and it is critical that the mistakes already made are not repeated.
