Massachusetts Gov. Charlie Baker (R) on March 26 signed sweeping legislation that puts the state on the hook to slash carbon emissions to 50%—below 1990 levels—by 2030 on its way to “net zero” emissions by 2050. While praising the intent of the landmarkclimate change bill, groups representing state construction and development sectors had raised concerns about some bill provisions related to local energy and building codes, with changes made.

根据新通过的法律，州环境官员将与目前的书籍制定更严格的建筑物和能源代码系列的计划。

Once the new rules are complete, cities, towns and suburbs across the state will have the option of replacing their current energy codes, a subset of the overall building code, with the new, and tougher state-designed “stretch” energy code.

That new and improved code, in turn, is likely to raise the cost of building new labs, offices, homes and apartments, requiring more money to be spent on everything from insulation to the latest and most efficient HVAC systems.

马萨诸塞州NAIOP政策和公共事务副总裁Anastasia Nicolaou表示，最终法案将该州制定新的伸展能源法规的截止日期延长了18个月。

That was a significant concession, with the previous bill calling for the new code to be in place in a year, an insufficient amount of time for such a complex issue, Nicolaou contends.

新法律本身是复杂的，长达数月的立法讨价还价的主题，其中包括贝克早期版本的否决权。

“We are really grateful the Legislature took steps to address some of the concerns of the business community,” NAIOP’s Nicolaou said.

The bill also calls for at least five public hearings on the new stretch energy code, in which industry groups like NAIOP and the Greater Boston Plumbing Contractors Association say they plan to take part and provide feedback to state regulators.

尼古拉说，此外，波士顿通过组建技术咨询小组来制定自己的零碳建筑法规制定自己的净碳建筑法规的努力也可以为州监管机构提供模型。

州立法领导人还对最终的气候变化法案进行了其他调整，这有助于缓解行业团体的关注。

The plumbing contractors’ association was relieved to see that a requirement that the tougher new net zero energy stretch codes called for under the new climate change law will not become mandatory for all communities by 2028, as was the case in earlier drafts of the legislation, said Andrew DeAngelo director of public affairs for the Greater Boston Plumbing Contractors Association.

Deangelo指出，州建筑法规和标准委员会将批准当前的全州建筑法规，将批准新标准，这是管道承包商集团推动的事情。

承包商团体一直担心州能源部将完全监督，这可能会导致新的代码“与现实脱节”，甚至可能允许社区禁止天然气连接。

Deangelo说：“我们没有得到我们想要的一切改变，但现在我们将在开发此代码的餐桌上席位，以确保它具有实用性和经济意义。”

Overall, the adoption of new and tougher stretch energy codes is expected to add cost to construction.

大波士顿房地产委员会总裁兼首席执行官格雷格·瓦西尔（Greg Vasil）指出，该项目以前本以前的价格为每平方英尺400至500美元，可能每平方英尺525美元。

即便如此，行业领导人说，他们了解减少碳排放的必要性。

瓦西尔（Vasil）指出，他的组织支持该众议院在2019年通过的气候变化法案。“每个人都同意我们绝对需要在气候变化上做些事情，”他说。
