Environmentally Sustainable Design

Advanced use of eco-design techniques

Energy efficiency is today a major ecological and economical challenge. It’s also becoming a legal requirement in many countries. As an answer to this challenge, Bouygues Construction has made sustainable construction a strategic priority. 46% of the Group’s R&D budget is allocated to this issue.

Environmental constraints and rising energy costs keep BYME aware of the need to design energy-efficient yet cost-effective MEP systems. We propose the most effective solutions in both environmental and economic terms throughout a project’s life cycle, supported by strong local engineering know-how, an ambitious group-wise knowledge sharing mechanism, and the use of advanced engineering tools (energy modelling, CFD, life cycle costing, etc). 

In France, our sister company BYES proposes energy performance contracts, with commitment to energy consumption on a long term basis.

From design to operations, we are fully committed to achieving performance targets agreed upon with our customers and partners. This translates into low energy consumption and environmentally friendly buildings. As a matter of fact, 100% of the buildings we design and build in Hong Kong and Singapore are awarded higher-tier environmental certifications (LEED, Green Mark, HK BEAM). More specifically, we contributed to the very first LEED Gold building in Singapore, as well as in Turkmenistan.

Trade & Industry Tower

The Trade and Industry Tower project in Kai Tak is set to define new standards for energy efficiency and greening in Hong Kong, and will be certified both under the local green building certification programme, BEAM Plus, and the LEED certification scheme. The project aims to achieve Platinum and Gold ratings in these schemes respectively.

To achieve such high standards of eco-construction, many sustainable strategies and energy conservation methods have been drawn up, most of them involving the building’s electrical and mechanical systems.

  • MVAC systems: Improved specific fan power (SFP), free cooling, air-side heat recovery, demand control ventilation;
  • Cooling systems: high efficiency district cooling system plant, and a higher temperature between the flow and return of the chilled water system;
  • Electrical systems: lower lighting power density and high efficiency lighting systems, occupancy, day lighting, photoelectric sensors, solar thermal hot water, building integrated photovoltaic (BIPV), lift regenerative power.
