Certifying Bodies for Net Zero Energy Buildings
The certifying bodies for Net Zero Energy Buildings in the US A are :
A) Department of Energy, DOE, an equivalent to the Malaysian Ministry of Energy
B) Zero Energy Commercial Building consortium
C) New Building Institute. NBI
A nonprofit organization that provides research and improved energy performance in commercial buildings
D)International Living Future Institute
The Programs surrounding the Net Zero Energy Buildings are :
The top 80% of 10 Architectural firms and 70% of the top 20 Architectural firms use The Challenge 2030.whereby all developments, new buildings and major renovation shall be carbon neutral by 2030 in the US and thereby reducing the temperature by 2 degree below the pre-industrial times.Net Zero Energy Buildings are also refereed too as Zero Energy Buildings.
2)Ashrae Vision 2020
Ashrae is a strong supporter of NZEB, and where Ashrae Vision 2020 was developed to promote energy Efficiency. NZE is defined as uses as much energy as it produces as measured at the site.
The Industry Codes and Regulations surrounding the Net Zero Energy Buildings in the world are:
1)Security Act of 2007
2)Energy Independence and Security Act( Malaysian Renewable Energy Act)
3)California Public Utilities Commission
4)Massachusetts Zero Energy Building Task Force
The parliament passed a directive to achieve NZE by 2019 but focused on residential buildings and not commercial buildings: UK-Zero Carbon Hub to be carbon neutral by 2016, Germany-Passivhaus, Netherlands-energy neutral by 2020, France to be Energy positive by 2020.
The Building Codes surrounding the Net Zero Energy Buildings in the USA are:
1)IgCC– International Green Construction Code
This code is developed in conjunction with AIA,USGBC (MGBC-a Malaysian equivalent body –Malaysian Green Building Council) , 2)ASHRAE,ASTM,IES
3)CalGreen, California Green Building
The Building rating and Energy Labelling Systems surrounding the Net Zero Energy Buildings in the USA are:
1) Energy Star
Is an energy labelling program of EPA( Environmental Protection Agency) and DOE( Department of Energy) It labels energy efficient products, homes, and commercial buildings. It scores on a table of 1 to 100.100 is a top performer. Energy Star does not recognize NZEBs. But the NZEB would score 90 in this program.
2) Leed/Green Building Index
The energy efficiency is the first and primary focus of the certification, one cannot obtain a platinum certification without designing for a high performance building. Incidentally the Net Zero building would easily obtain the Platinum with a marginal additional cost
3) Living Building Challenge by International Living Future Institute
Defines Imperatives for Net Zero Energy:
- Net Zero Energy-if this imperative is not achieved it will not be qualified for the Living Building Challenge. The definition of NZEB are on: renewable energy, photo voltaic, wind turbines, water powered micro turbines, direct geo thermal. Biomass or combustion of any kind is not allowed. Hydrogen cell is allowed if energy is fueled by Hydrogen. Off grid connection is a must.
- Site Imperatives-Site is restricted for gray fields and brownfields
- Equity Imperatives-fresh air, sunlight and natural waterways
- Beauty Imperatives-Beauty, spirit, inspiration and education
