Water Quality, new requirements for water testing have were introducted with the WSD Circular Letter No. 9/2017, here is the LINK

The new criteria is worthy of note because it requires testing of stagnant water to idendify metals leaching from the water piping or fittings into the potable water supply.

However, it's only applicable to new buildings and in Hong Kong buildings can be vacant for years after completion.

beam neighbourhood rating tool, BEAM ND
The BEAM Neighbourhood rating tool, or BEAM ND, is the latest member of the suite of BEAM Hong Kong Green Building rating tools. This rating tool covers community-wide developments, and is designed for assessing and rating the master plan stage.

If you're familar with BEAM rating tools, the format and content of BEAM ND is easily recognized, using the same system for scoring points, in each of the categories.

A power outage at Delta Airlines USA caused their datacenter and then the IT system to fail, creating worldwide problems. "This is not the first major incident, and surely it will not be the last, the approach to risk is simply ignore it." Herbert said.

The costs, well the cost is unknown at this stage, the backlog of flights and passengers is on-going, but it will run into many USD millions. There are media reports indicating that a switch failed, which seems odd since an obvious single point of failure should have planned redundancy.

11 July 2016 Building Air Balance. Considering the importance of good ventilation, the ratio of exhaust air flow and replacement make-up air is often overlooked, with dire consquences for your health. Contamination can be drawn into your breathing space from drainage pipes, with bacteria. In 2003 SARS was circulated by air from poor drainage systems.

Chilled Water Piping Losses

Polystrene thermal insulation, banned due to fire and smoke risk, were replaced by glass fibre, the only and therefore preferred choice at that time. But glass fibre was never intended for chilled water applications, it was developed and used to insulate walls.

Chilled water piping cladding covered with condensation
indicating a serious problem, wasting energy

In the event that the vapour barrier installation is not 100% perfect, moist air condenses on chilled water piping, destroying the thermal resistance of the insulaton.

Capillary action and gravity causes the water damage to widen, but it is difficult to notice the losses, the concealed chilled water gets warmer and warmer.

Modern piping thermal insulation is less likley to be damaged by condensation.

The sports hall roof collaspe at City University on 20 May 2016 has caused alarm bells about green roofing in Hong Kong. Energy expert John A. Herbert speaking on RTHK radio news explained "A reflective white roof is a better alternative for existing buildings it can lower the cooling load and reduce the cost for air conditioning space below" Herbert said.

A white roof works by reflecting the energy from the sun, it avoids absorbing energy, more effectively than a regular lawn used in Hong Kong, it will cost less to maintain, and does not add wieght which is an important factor for an existing structure.

Whilst it does mitigate the urban heat island effect, just like a green roof, he agreed that a white roof does not tick the biodiversity box "a lawn is not meadow of wild flowers providing habitat for countless species, its just a lawn" Herbert said.

reflective white roof, hong kong

27 May 2016 - A reflective white roof is better than a lawn, a white roof is not expensive solution, it protects the waterproofing membrane, increasing roof longvity, and reduces the solar gain from the by more than 50% for air conditioned areas beneath

31 December 2015
Besides the hottest year on record in terms of temperature, Hong Kong also achieved another record, the highest number of Legionairres' Disease cases, 66 cases were reported in 2015, significantly more than 28 cases in 2013 and 41 cases in 2014. the majority 79% are believed to be local (legionella case breakdown). And as we know Legionella is generally under-reported. Many of the patients were treated as Pneumonia cases before the Legionella diagnosis was made, again not a surprize given that it generally presents as a pneumonia.

Furthermore, Legionella cases both worldwide and locally occurred in the colder months, hopefully dispelling the myth that Legionella is only a summer time risk.

Although EMSD has been monitoring cooling towers in Hong Kong, still high and very high Legionella counts persist. EMSD reported in 2015 that eight (8) cooling towers exceeded 1,000 cfu/ml

2015 was also notable because ASHRAE published ASHRAE Standard 188-2015 Legionellosis: Risk Management for Building Water Systems

Lightning Protection Installation

Indeed you may have read that lightning recently struck a Google data centre, but is your data safe? Has you operation been checked? All too often, the investigation starts after the incident has already occurred.

John A. herbert
Perhaps Kelcroft's attention to detail does count

The cable connection is damaged, just another another item added to the defects list, details that others overlook, Kelcroft uncovers, making data centre safer.

Backup systems are critical for data centre operations, they normally operate under emergency circumstances, so it is vital that all batteries are installed and commissioned correctly?

John A. herbert
Battery backup system continuity failed

Kelcroft's independent checking, with our detail approach, uncovered this failed backup system BEFORE data centre operations commenced.

A new building with poorly designed air conditioning, is it really 2015? An engineer should know that locating an air grille near the wall is just asking for trouble, the beauty of infra-red imaging, it allows us to easily demonstrate defects to non-engineers.

Do you want your buildings designed to a particular standard or actual performance? Stakeholders in Hong Kong have always demanded performance over promises.

Furthermore, he explained that BEAM has changed the industry, engineers are now forced to account for Hong Kong's skyscrapers, and now design water efficient systems to gain BEAM certification. .....learn more
