LPD exempt

The Hong Kong Building Energy Code version 2012 rev1 and 2015 Lighting Power Density (LPD) requirement does NOT apply where the room lighting load does not exceed 100 watt (2012 rev1 page 13) and 70 watt  (2015 page 14) respectively.

2015-lpd 2012-lpd

by implication the target is the TOTAL power (lighting and control gear).  So what does that mean? for BEC 2015, it means a store room with total power is less than 70w you are not required to comply with the 9w/sqm LPD or the lighting control requirement.

E-Bus for Hong Kong? Not soon Enough

Hong Kong may have a new electric bus, sooner than you think. The new vehicle was spotted around town last week, outside HKPC in Kowloon Tong, and at the Eco Asia Expo 2015 exhibition.

Considering Hong Kong’s small area, this E-Bus must be killer app for Hong Kong’s urban pollution problems. I understand that many argue against EV’s because the rational is that EV’s merely move the pollution problem from our lungs to the distant electricity generating stations, and they claim that is a problem?

Repeated studies have shown the pollution at street level is often intolerable with excess PM2.5 PM10 and NOX. (nitrogen oxides). However, these power generating stations already have pollution control measures in place, and are discharged far from the lungs of busy pedestrians presently dodging the fumes in Central.

Burning diesel at street level should be a crime nowadays! Now we know, the diesel combustion (petroleum diesel not bio diesel) process the combustion is incomplete, and creates tiny microscopic soot particles, they are so small they are easily inhaled, hence the grave concern over particulates in the PM2.5-10 range. Hong Kong’s EPD in fact publish the monitoring data:

And the source of those PM2.5 and PM10 particulates? the overwhelming majority are created by diesel engine discharged at lung (street) level. Furthermore, I understand that the E-Bus creators (designed in Hong Kong!) have useful applications in mind for the ‘used’ batteries, to avoid creating another waste problem dealing with spent batteries. I had a tour, inside it looks like every other Hong Kong bus, in fact you would find it hard to distinguish between the diesel  version, except for the tailpipe.

Another sustainability perspective to consider, beside being conceived and designed in Hong Kong, it is manufactured close to home, avoiding the related emissions caused from importing buses from Europe which I understand is the usual practice.

Let us hope it is on the road, here in Hong Kong, sooner rather than later. One of Hong Kong’s key selling points must be the fantastic low cost, public transport system, but can it be improved? Of course, there is always room for improvement, as Paul Zimmerman points out, there are water taxi’s and ferries that would improve connectivity across the harbour, however the Hong Kong public transport system is one that many cities envy.

Consensus

Built on local consensus, indeed a lot has changed since the first BI draft, thanks to the contributions of the local community. The draft BI was examined and scrutinised  by 100+ Hong Kong building Professionals from the local institutions, through two workshops, and then followed with a three month long PUBLIC consultation period (April 2013-July 2013). Indeed the process is really one of built-in continuous refinement, the BI manual has a page designed to submit your comments.

Conditions

For projects upto 999 sqm (internal floor area) Applicants should fulfil the following three conditions which are simultaneously met:

(a) the building owner is a charitable organisation/Non-government organisations/Non-profit organisations; (b) the building owner does not receive other sources of fund to cover the expense of that assessment fee; and (c) the building is not built for generating commercial income;

Meanwhile, applicants should demonstrate the following criteria:

  1. Help deliver and project a symbolic image and word of mouth of BI.

  2. Demonstrate their strong commitment in pursuing green.

  3. Have good and established reputation in the market.

  4. Go in line with BSL’s mission and vision.

  5. Wish to pursue green but suffering and limited to a stringent budget.

Airing your clean laundry

by John A. Herbert
no-drying_800w

It was beautiful weather today, it was hot, so hot in fact that the Hong Kong Observatory promulgated the Very Hot Weather warning, a glorious day indeed for drying your laundry in the sunshine, alas not in Hong Kong. Building and estate managers, for reasons unknown, actively prohibit carbon free laundry drying, stainless prohibition signs litter the site, proclaiming no drying. Perhaps they deem it to be ugly? but enterprising hongkongers hang their duvets, sheets, and bedding just outside the estate officers influence and control. This walkway (photo below) is a good example, just beyond the estate boundary, it doubles as a carbon free clothes drying area, beating the often lousy provisions provided at home and without burning fossil fuel. Is it time for a change of policy?

drying_800w

It is said, you’ll never find an architect visiting their finished project, but sustainable living, demands more time and energy devoted for more thoughtful design not less. Carbon free clothes drying isnt going to spark the revolution, but its a small step in the right direction.

diesel powered irrigation II

by John A. Herbert
Hong Kong, a diesel truck coasts along the fast lane of the highway (near MegaBox) to water the plants. It was a hot day, so spraying (misting) water into the air helps it evaporate easily wasting water.

At the same time the opportunity to use rainwater from the highway directly above is loss because it is piped and needlessly dumped into the common sewer system (Hong Kong has a single sewer and storm water sewerage system), there is a better way!

Design vs Performance

Building regulations, Energy codes, and like tend to specify a performance parameters for the design stage, not actual building performance. The building code requires a certain OTTV  (Overall Thermal Transmittance Value) defined by w/sqm, for the building envelope. However, the delivered performance is never measured.

The energy code also requires air conditioning chillers to meet certain catalogue performance targets, however the nominal capacity is tested at steady state standard ARI conditions, unlike real life which suffers hourly variations.

zcb_45_600w

Hong Kong’s Nett Zero Energy building, known locally as the Zero Carbon Building or ZCB has a display which clearly shows (recorded 17 October 2013)  the energy consumption (277,597 kwh) exceeds the energy generated (183,470 kwh). therefore the ZCB has only provided 66% of the total energy demand, and we must assume that no energy exported to the grid.

zcb_46_600w

ABOVE: Watering the lawn at Hong Kong’s ZCB is a low technology affair (17 Oct. 2013)

Setting design performance goal is admirable, but that is only one aspect of building performance, and don’t expect design parameters alone to create high performance, low carbon buildings.

Actual data, for example the BEEO Cap 610 demands that every commercial building post EMSD form EE5, that provides facts, and for the first time allows comparison between performance of similar building types.

BEAM for Offices Training

BEAM for offices training

There is about 40 Million sqm of office space in Hong Kong, with renovation and fitting out projects representing the bulk of active projects each and every day. Because of their number and repetitive nature these projects have a significant impact on the environment and our quality of life. Responding to market demand and recognising those who choose to do this work in an environmentally friendly fashion and offer users a healthier workspace, a new green building rating tool was created locally by BEAM Society Limited: BEAM Plus BEAM for green officesInteriors. The new addition to the suite of BEAM green rating tools covers fitting out works for commercial premises, offices, hotels, and retail spaces. This two (2) hour training course is specially designed solely for BEAM Professionals. It will introduce the new framework, grading, credits and features of the new rating tool. Undertaking this training course is a prerequisite for all BEAM Professionals to submit Interiors projects for assessment and certification using the BEAM Plus Interiors rating tool.

Hong Kong Office Rating Tool – BEAM Interiors

Hong Kong BEAM Interiors for Offices, retail and fitouts

Well here it is, after countless pro-bono hours, and a few sleepless nights, BEAM PLUS Interiors (BI) is published!  To the existing BEAM users, the new rating tool will be reassuringly familiar, yes its part of the BEAM suite, and yet its a little different.

Whilst still broadly on based on the existing tool, BEAM Interiors 2008 tool, BEAM NB and EB, this marks a renewed focus on science based sustainability, BEAM has introduced some updated concepts for it’s framework, extra categories  and new credit criteria format.

Ok, I admit it, I did chair the BI steering committee, so I am hoping you’ll find the the new manual exciting, the new credit criteria refreshingly clear, with fewer opportunities for confusion.  But if you find a glitch, do drop a line to BSL and let us know your thoughts, it designed for continuous development. I am sure critics will already be comparing it to LEED, but this tool is a local, Hong Kong rating tool, designed in Hong Kong, for Hong Kong projects, only time will tell if the other tools can catch up! The Official launch, and project registration will commence around September 2013, so that gives you time to familiarise yourself with the new tool and the latest credit requirements.
