BEC’s Energy Efficient Retrofit Guide & Calculator Launch Event

Over 80 Volunteers of 11 BEC Member Companies Help Avoid Refuse to Landfills

Hong Kong, 12 Dec 2017 - Business Environment Council Limited 商界環保協會有限公司 (“BEC”) launches its “Guide to Energy Efficient Retrofits of Office and Hotel Buildings: identifying cost effective solutions” and “Retrofit Calculator” today at BEC Auditorium. The Retrofit Guide and the Calculator are the outputs of a project supported by the HKSAR Government, offering buildings owners, managers and tenants information to support their decisions in retrofitting existing buildings and in developing the business case to do so.

BEC is launching these enabling tools because of the importance of managing consumption of energy in Hong Kong’s buildings in order to reduce carbon emissions, and to avoid unnecessary air pollution, as well as for efficiency and thermal comfort reasons.

The enabling tools released are as follows:

  1. The Retrofit Guide: provides a description of those mature energy efficient technologies that will help achieve significant carbon/energy savings and explains the approximate net costs and the payback periods for doing so. It focuses on existing commercial buildings, namely offices and hotels.  Information is provided in a simple visual and easy to use format to support both technical and non-technical personnel in their decision-making.
  2. The Retrofit Calculator: this is an easy-to-use excel tool designed to estimate the costs and energy saving performance of individual technologies and initiatives with user-customized specifications.

Ir Alfred Sit, Director of Electrical and Mechanical Services, Electrical and Mechanical Services Department, HKSAR Government said, “Energy efficiency and conservation is central to the HKSAR Government’s environmental policies, as reflected in the Energy Saving Plan and Climate Action Plan 2030+. Energy saving should no doubt be our common goal, not just for cost concerns but also for our aspiration to thrive in a clean and green environment, as well as to tackle the global problem of climate change. I would like to encourage our stakeholders to actively participate in energy saving efforts. With the launch of this Guide and Calculator by Business Environment Council, they could provide an easy reference for stakeholders on investment in energy efficient technologies.”

Chairman of BEC, Mr Richard Lancaster, said, “Energy is an essential part of daily life. But effective management of energy demand is important in helping reduce carbon emissions, improve our air quality and run our businesses efficiently. Businesses need good, easy to understand information on energy saving initiatives to help them decide where their investments will get the best returns. That is why BEC has developed this Retrofit Guide and Calculator. It offers practical assistance and clear advice to property owners and managers to help them achieve highly energy efficient buildings.”

Mr Tony Small, Chairman of BEC’s Energy Advisory Committee which initiated this project and steered it to this conclusion said, “I am pleased to promote this Guide to Energy Efficient Retrofits of Commercial Buildings to all those looking to understand better the steps they should be taking. It shows the approximate cost savings, energy savings and return on investment from the most important energy saving technologies and initiatives in simple “marginal abatement cost curves”, calculated through robust simulations. The Retrofit Calculator that accompanies the Guide is a simple, easy-to-use tool that is able to provide approximate energy and cost savings data for individual buildings.”

Key Facts & Figures

Climate Action Plan

70% of Hong Kong’s carbon emissions are from electricity

90% of electricity is used in buildings


Energy Saving Plan

Energy Saving Target of 40% by 2025 has been set

36% of carbon emissions relate to energy usage by commercial buildings

5% target from 2014-2020 for Government Buildings


Key Findings

  • The most impactful measures depend on the type of office building.
  • For example for Type 1 office buildings, the most impactful technologies in terms of carbon abatement include: fresh air demand control measures, oil-free water-cooled chillers, variable speed drive water-cooled chillers, solar control window film, high volume low speed fans, and  LED lighting.
  • For hotels: solar control, window film, LED lighting, high performance glazing, smart controls and DC fan coils have the biggest impact.
  • Payback periods for each technology have also been included, following a modelling exercise.
