Detailed Green Building Assessment and Green Mark Certification Report

This report assesses the feasibility of obtaining Green Mark Gold certification for a headquarters building, focusing on energy efficiency. The report begins by identifying the appropriate BCA Green Mark assessment criteria and the certification process, emphasizing the importance of energy efficiency, lighting power, tenant awareness, environmental policies, and management involvement. It includes a detailed assessment of current and targeted Green Mark score points, providing calculations for energy savings, replacement of electricity by renewable energy, and Energy Efficiency Index based on the provided monthly electricity consumption data. The report also provides a breakdown of the targeted scoring to achieve the Green Mark Gold award, explaining the necessary reasons for all categories under the Green Mark framework, and includes calculations such as percentage savings to derive the points scored. Appendix A provides building information, including monthly electricity consumption, cooling load profile, air-conditioning system efficiency, and equipment details, to support the assessment. The report aims to provide a comprehensive guide to sustainable building practices and the Green Mark certification process.

Module: Green Building Assessment Standards
Question 1
You are required to demonstrate your understanding of what was learnt in your GMFM course
by submitting the application with relevant supporting documents for Green Mark certification.
As the project leader, assess and recommend an appropriate version of BCA Green Mark
assessment criteria for the headquarter building.
The assessment criteria that will be used for headquarter building will be energy efficiency,
which will comprise of ensuring that the following areas have the highest scores for it to be
able to win the Green mark gold, the area under consideration will include, monthly electrical
meter monitory through reading it, the performance based on the thermal on the envelope of the
building, thermal parameters, system of air conditioning, density of light, lifts having efficiency
of energy, management of energy, energy efficient renewed and finally artificial lighting.
(5 marks)

Question 2
Prior to assessing the building’s current score, explain and discuss with the management the
certification process with BCA in order to obtain Green Mark Gold for the Green Mark criteria
recommended.
In order to achieve Green Mark Gold then the management should ensure that the following
areas or sections will have to achieve the stipulated points.
i. Under the energy efficiency management should ensure that it is possible for it to
achieve a minimum of four points.
ii. Under lighting power the budget should be able to achieve a minimum of 24%
iii. Creation of awareness on the building tenants regarding the sustainable
environment, the management should ensure this section achieves three points.
iv. Achievement of three points by ensuring that environmental policies and review on
it.
v. Setting up a reminder that is capable of maintaining air conditioning at 240 point.
vi. Achievement of two points on the involvement of management in all the activities.
vii. Achieving two points by providing a green corner in each house unit with enough
house working material.
viii. Appoint in each and every floor an environmental chairman to ensure every sector
that involvement environment in each floor is totally addressed to the management
in time.

Question 3
Please also assess and compute the assessment fee (including GST) in your briefing to the
management. Include a screen shot of the assessment fee guide from BCA website that you
have made reference to.

Size Existing HQ building

Assessment fee for
certification
Medium and above 37,800 = $8,900 for the first 15,
000 m2
= $0.15 *(37800 – 15000)
= $3,420
Total = $8900 + $34200 =
$12,320
GTS = 7% * $12,320
= $862.40
Net cost = $8900 + $34200
+ $862.40 = $13,182.40

Question 4
After you have completed your assessment, you are required to appraise and present to the
management of the company current Green Mark score points of the existing headquarter office
building based on the preliminary findings. (Preliminary findings are provided in Appendix A)
